Controls: left and right arrows to change the sorting column, r to invert the sorting order, o to toggle the --only option, p to toggle the --processes option, a to toggle the --accumulated option, i to change I/O priority, q to quit, any other key to force a refresh.c s� yt jt jd� W n t jk r0 td� Y nX tjtdt d�} | j ddddd d d � | j d d dddd� | j ddddddd� | j ddddd d d d � | j d d!dd"d#d$d%d&� | j d'd(d)d*d#d+d,d&� | j d-d.dd/d d0d � | j d1d2dd3d d4d � | j d5d6dd7d d8d � | j d9d:dd;d<d� | j d=d>d?d@dAdBd � | j dCddDd tj d � | j � \�}|�rt| j dEdFj |� � t�� �j�p�g �_�j�p��j�p��j�_�fdGdH�� �j�ṙ fdIdJ�}t|� n� � d S )KNr z8unable to set locale, falling back to the default localeziotop )Zusage�versionz-oz--only� store_truer� Fz1only show processes or threads actually doing I/O)r� �destr �helpz-bz--batchrT znon-interactive mode)r� r� r� z-nz--iterr rd ZNUMz-number of iterations before ending [infinite])�typer� �metavarr� z-dz--delayr rg z#delay between iterations [1 second]ZSECr )r� r� r� r� r z-pz--pid�pids�appendz"processes/threads to monitor [all]r� )r� r� r� r� r� z-uz--userr� Zuserszusers to monitor [all]ZUSERz-Pz --processesr� z$only show processes, not all threadsz-az --accumulatedr* z)show accumulated I/O instead of bandwidthz-kz --kilobytesr! z.use kilobytes instead of a human friendly unitz-tz--timer, z.add a timestamp on each line (implies --batch)z-qz--quiet�countr� r z/suppress some lines of header (implies --batch)z --profile�profilezUnexpected arguments: rw c s t � �S )N)r� r )r" r r r) � s zmain.<locals>.<lambda>c s y � � W n Y nX d S )Nr r )� main_loopr r �safe_main_loop� s z main.<locals>.safe_main_loop)�locale� setlocale�LC_ALL�Errorr> �optparseZ OptionParser�USAGEr Z add_optionZ SUPPRESS_HELP� parse_argsrY r� r r� rT r, r� r� r� )�parserrh r� r )r� r" r �main\ s\ r ).Z __future__r rW ri r r r r� r^ r� ra r, Z iotop.datar r r r r r Z iotop.versionr Ziotopr Z iotop.ioprior r r r$ r& r7 r@ r� r= rA rE rF rG rH �objectrI r� r� r� �argvr r r r r r �<module> sH $$ site-packages/iotop/__pycache__/ioprio.cpython-36.pyc 0000644 00000010102 15152656744 0016566 0 ustar 00 3 B��Qw � @ s� d dl Z d dlZd dlZd dlZdBdCdDdEdFdGdHdIdJdKdLg ZdMdNdOdPdQdRdSdTdUdVdWg Zd"d#� ZG d$d%� d%e�Zee�Z ee�Z ye j dd&d'�Z W n e k � r� e j d�Z Y nX e jZdd(d)d*gZd+Zd,Zd+e> d+ Zd-d.� Zd/d0� Zd1d2� Ze jZed3�\ZZZZZ Z e j Z d Z d4d5� Z d6d7� Z!d8d9� Z"d:d;� Z#d<d=� Z$e%d>k�r�d dl&Z&e'e&j(�d?k�rle)e&j(d+ �Z*nej+� Z*e,d@e*� e,dAe!e*�� dS )X� N�alpha�*� �arm*�; �i*86�" �ia64*� �parisc*� �powerpc*� �s390*� �sparc*�� �sh*�! �x86_64*�32bit�64bit� � �: � � � � �� � � c C sL t j� d }tj� d }x.| D ]&\}}}tj||�r tj||�r |S q W d S )N� r )�os�uname�platformZ architecture�fnmatch)Z syscall_listZarch�bitsZcandidate_archZcandidate_bitsZ syscall_nr� r( � /usr/lib/python3.6/ioprio.py�find_ioprio_syscall_number9 s r* c @ s e Zd Zdd� ZdS )�IoprioSetErrorc C s0 yt j|�| _W n tk r* || _Y nX d S )N)r# �strerror�err� TypeError)�selfr- r( r( r) �__init__C s zIoprioSetError.__init__N)�__name__� __module__� __qualname__r0 r( r( r( r) r+ B s r+ T)� use_errnoZrtZbe�idle� � c C s: yt j| �} W n tk r, t jd �} Y nX | t> |B S )N)�PRIORITY_CLASSES�index� ValueError�IOPRIO_CLASS_SHIFT)� ioprio_class� ioprio_datar( r( r) � ioprio_valueY s r> c C s t | t?

Some notable features include the fact that its implemented entirely in Python and it uses LALR(1) parsing which is efficient and well suited for larger grammars. PLY provides most of the standard lex/yacc features including support for empty productions, precedence rules, error recovery, and support for ambiguous grammars. PLY is extremely easy to use and provides very extensive error checking. It is compatible with both Python 2 and Python 3.

It supports almost all record types. It can be used for queries, zone transfers, and dynamic updates. It supports TSIG authenticated messages and EDNS0. dnspython provides both high and low level access to DNS. The high level classes perform queries for data of a given name, type, and class, and return an answer set. The low level classes allow direct manipulation of DNS zones, messages, names, and records.

To retrieve devices, simply iterate over an instance of this class. This operation yields :class:`Device` objects representing the available devices. Before iteration the device list can be filtered by subsystem or by property values using :meth:`match_subsystem` and :meth:`match_property`. Multiple subsystem (property) filters are combined using a logical OR, filters of different types are combined using a logical AND. The following filter for instance:: devices.match_subsystem('block').match_property( 'ID_TYPE', 'disk').match_property('DEVTYPE', 'disk') means the following:: subsystem == 'block' and (ID_TYPE == 'disk' or DEVTYPE == 'disk') Once added, a filter cannot be removed anymore.

A :class:`Monitor` objects connects to the udev daemon and listens for changes to the device list. A monitor is created by connecting to the kernel daemon through netlink (see :meth:`from_netlink`): >>> from pyudev import Context, Monitor >>> context = Context() >>> monitor = Monitor.from_netlink(context) Once the monitor is created, you can add a filter using :meth:`filter_by()` or :meth:`filter_by_tag()` to drop incoming events in subsystems, which are not of interest to the application: >>> monitor.filter_by('input') When the monitor is eventually set up, you can either poll for events synchronously: >>> device = monitor.poll(timeout=3) >>> if device: ... print('{0.action}: {0}'.format(device)) ... Or you can monitor events asynchronously with :class:`MonitorObserver`. To integrate into various event processing frameworks, the monitor provides a :func:`selectable <select.select>` file description by :meth:`fileno()`. However, do *not* read or write directly on this file descriptor. Instances of this class can directly be given as ``udev_monitor *`` to functions wrapped through :mod:`ctypes`. .. versionchanged:: 0.16 Remove :meth:`from_socket()` which is deprecated, and even removed in recent udev versions. c C s || _ || _|j| _d| _d S )NF)�contextZ_as_parameter_�_libudev�_started)�selfr Z monitor_p� r � /usr/lib/python3.6/monitor.py�__init__V s zMonitor.__init__c C s | j j| � d S )N)r Zudev_monitor_unref)r r r r �__del__\ s zMonitor.__del__�udevc C s> |dkrt dj|���|jj|t|��}|s4td��| ||�S )a� Create a monitor by connecting to the kernel daemon through netlink. ``context`` is the :class:`Context` to use. ``source`` is a string, describing the event source.

Multiple subsystem (property) filters are combined using a logical OR, filters of different types are combined using a logical AND. The following filter for instance:: devices.match_subsystem('block').match_property( 'ID_TYPE', 'disk').match_property('DEVTYPE', 'disk') means the following:: subsystem == 'block' and (ID_TYPE == 'disk' or DEVTYPE == 'disk') Once added, a filter cannot be removed anymore.

Run an interruptible system call in a loop and retry if it raises EINTR. The signal calls that may raise EINTR prior to Python 3.5 are listed in PEP 0475. Any calls to these functions must be wrapped in eintr_retry_call in order to handle EINTR returns in older versions of Python. This function is safe to use under Python 3.5 and newer since the wrapped function will simply return without raising EINTR.

Consequently, the version number returned by this function is a single integer, and not a tuple (like for instance the interpreter version in :data:`sys.version_info`). As libudev itself does not provide a function to query the version number, this function calls the ``udevadm`` utility, so be prepared to catch :exc:`~exceptions.EnvironmentError` and :exc:`~subprocess.CalledProcessError` if you call this function. Return the version number as single integer. Raise :exc:`~exceptions.ValueError`, if the version number retrieved from udev could not be converted to an integer. Raise :exc:`~exceptions.EnvironmentError`, if ``udevadm`` was not found, or could not be executed. Raise :exc:`subprocess.CalledProcessError`, if ``udevadm`` returned a non-zero exit code.

This class subclasses the ``Mapping`` ABC, providing a read-only dictionary mapping property names to the corresponding values. Therefore all well-known dicitionary methods and operators (e.g. ``.keys()``, ``.items()``, ``in``) are available to access device properties. Aside of the properties, a device also has a set of udev-specific attributes like the path inside ``sysfs``. :class:`Device` objects compare equal and unequal to other devices and to strings (based on :attr:`device_path`). However, there is no ordering on :class:`Device` objects, and the corresponding operators ``>``, ``<``, ``<=`` and ``>=`` raise :exc:`~exceptions.TypeError`. .. warning:: **Never** use object identity (``is`` operator) to compare :class:`Device` objects. :mod:`pyudev` may create multiple :class:`Device` objects for the same device. Instead compare devices by value using ``==`` or ``!=``. :class:`Device` objects are hashable and can therefore be used as keys in dictionaries and sets.

This class subclasses the ``Mapping`` ABC, providing a read-only dictionary mapping property names to the corresponding values. Therefore all well-known dicitionary methods and operators (e.g. ``.keys()``, ``.items()``, ``in``) are available to access device properties. Aside of the properties, a device also has a set of udev-specific attributes like the path inside ``sysfs``. :class:`Device` objects compare equal and unequal to other devices and to strings (based on :attr:`device_path`). However, there is no ordering on :class:`Device` objects, and the corresponding operators ``>``, ``<``, ``<=`` and ``>=`` raise :exc:`~exceptions.TypeError`. .. warning:: **Never** use object identity (``is`` operator) to compare :class:`Device` objects. :mod:`pyudev` may create multiple :class:`Device` objects for the same device. Instead compare devices by value using ``==`` or ``!=``. :class:`Device` objects are hashable and can therefore be used as keys in dictionaries and sets.

Home-page: http://python-requests.org Author: Kenneth Reitz Author-email: me@kennethreitz.org License: Apache 2.0 Description: Requests: HTTP for Humans™ ========================== [](https://pypi.org/project/requests/) [](https://pypi.org/project/requests/) [](https://pypi.org/project/requests/) [](https://codecov.io/github/requests/requests) [](https://github.com/requests/requests/graphs/contributors) [](https://saythanks.io/to/kennethreitz) **If you're interested in financially supporting Kenneth Reitz open source, consider [visiting this link](https://cash.me/$KennethReitz). Your support helps tremendously with sustainability of motivation, as Open Source is no longer part of my day job.** Requests is the only *Non-GMO* HTTP library for Python, safe for human consumption.  Behold, the power of Requests: ``` {.sourceCode .python} >>> r = requests.get('https://api.github.com/user', auth=('user', 'pass')) >>> r.status_code 200 >>> r.headers['content-type'] 'application/json; charset=utf8' >>> r.encoding 'utf-8' >>> r.text u'{"type":"User"...' >>> r.json() {u'disk_usage': 368627, u'private_gists': 484, ...} ``` See [the similar code, sans Requests](https://gist.github.com/973705). [](http://docs.python-requests.org/) Requests allows you to send *organic, grass-fed* HTTP/1.1 requests, without the need for manual labor. There's no need to manually add query strings to your URLs, or to form-encode your POST data. Keep-alive and HTTP connection pooling are 100% automatic, thanks to [urllib3](https://github.com/shazow/urllib3). Besides, all the cool kids are doing it. Requests is one of the most downloaded Python packages of all time, pulling in over 11,000,000 downloads every month. You don't want to be left out! Feature Support --------------- Requests is ready for today's web. - International Domains and URLs - Keep-Alive & Connection Pooling - Sessions with Cookie Persistence - Browser-style SSL Verification - Basic/Digest Authentication - Elegant Key/Value Cookies - Automatic Decompression - Automatic Content Decoding - Unicode Response Bodies - Multipart File Uploads - HTTP(S) Proxy Support - Connection Timeouts - Streaming Downloads - `.netrc` Support - Chunked Requests Requests officially supports Python 2.7 & 3.4–3.7, and runs great on PyPy. Installation ------------ To install Requests, simply use [pipenv](http://pipenv.org/) (or pip, of course): ``` {.sourceCode .bash} $ pipenv install requests ✨🍰✨ ``` Satisfaction guaranteed. Documentation ------------- Fantastic documentation is available at <http://docs.python-requests.org/>, for a limited time only. How to Contribute ----------------- 1. Check for open issues or open a fresh issue to start a discussion around a feature idea or a bug. There is a [Contributor Friendly](https://github.com/requests/requests/issues?direction=desc&labels=Contributor+Friendly&page=1&sort=updated&state=open) tag for issues that should be ideal for people who are not very familiar with the codebase yet. 2. Fork [the repository](https://github.com/requests/requests) on GitHub to start making your changes to the **master** branch (or branch off of it). 3. Write a test which shows that the bug was fixed or that the feature works as expected. 4. Send a pull request and bug the maintainer until it gets merged and published. :) Make sure to add yourself to [AUTHORS](https://github.com/requests/requests/blob/master/AUTHORS.rst).

This makes platform-native TLS available to urllib3 users on macOS without the use of a compiler. This is an important feature because the Python Package Index is moving to become a TLSv1.2-or-higher server, and the default OpenSSL that ships with macOS is not capable of doing TLSv1.2. The only way to resolve this is to give macOS users an alternative solution to the problem, and that solution is to use SecureTransport. We use ctypes here because this solution must not require a compiler. That's because pip is not allowed to require a compiler either. This is not intended to be a seriously long-term solution to this problem. The hope is that PEP 543 will eventually solve this issue for us, at which point we can retire this contrib module. But in the short term, we need to solve the impending tire fire that is Python on Mac without this kind of contrib module. So...here we are.

This makes platform-native TLS available to urllib3 users on macOS without the use of a compiler. This is an important feature because the Python Package Index is moving to become a TLSv1.2-or-higher server, and the default OpenSSL that ships with macOS is not capable of doing TLSv1.2. The only way to resolve this is to give macOS users an alternative solution to the problem, and that solution is to use SecureTransport. We use ctypes here because this solution must not require a compiler. That's because pip is not allowed to require a compiler either. This is not intended to be a seriously long-term solution to this problem. The hope is that PEP 543 will eventually solve this issue for us, at which point we can retire this contrib module. But in the short term, we need to solve the impending tire fire that is Python on Mac without this kind of contrib module. So...here we are.

Example usage:: from urllib3 import PoolManager from urllib3.contrib.appengine import AppEngineManager, is_appengine_sandbox if is_appengine_sandbox(): # AppEngineManager uses AppEngine's URLFetch API behind the scenes http = AppEngineManager() else: # PoolManager uses a socket-level API behind the scenes http = PoolManager() r = http.request('GET', 'https://google.com/') There are `limitations <https://cloud.google.com/appengine/docs/python/urlfetch/#Python_Quotas_and_limits>`_ to the URLFetch service and it may not be the best choice for your application. There are three options for using urllib3 on Google App Engine: 1. You can use :class:`AppEngineManager` with URLFetch. URLFetch is cost-effective in many circumstances as long as your usage is within the limitations. 2. You can use a normal :class:`~urllib3.PoolManager` by enabling sockets. Sockets also have `limitations and restrictions <https://cloud.google.com/appengine/docs/python/sockets/ #limitations-and-restrictions>`_ and have a lower free quota than URLFetch. To use sockets, be sure to specify the following in your ``app.yaml``:: env_variables: GAE_USE_SOCKETS_HTTPLIB : 'true' 3. If you are using `App Engine Flexible <https://cloud.google.com/appengine/docs/flexible/>`_, you can use the standard :class:`PoolManager` without any configuration or special environment variables. � )�absolute_importN� )�urljoin)� HTTPError� HTTPWarning� MaxRetryError� ProtocolError� TimeoutError�SSLError)�RequestMethods)� HTTPResponse)�Timeout)�Retry� )�_appengine_environ)�urlfetchc @ s e Zd ZdS )�AppEnginePlatformWarningN)�__name__� __module__� __qualname__� r r � /usr/lib/python3.6/appengine.pyr G s r c @ s e Zd ZdS )�AppEnginePlatformErrorN)r r r r r r r r K s r c @ sX e Zd ZdZddd�Zdd� Zdd � Zddddejfd d �Z d d � Z dd� Z dd� Z dS )�AppEngineManagera Connection manager for Google App Engine sandbox applications. This manager uses the URLFetch service directly instead of using the emulated httplib, and is subject to URLFetch limitations as described in the App Engine documentation `here <https://cloud.google.com/appengine/docs/python/urlfetch>`_. Notably it will raise an :class:`AppEnginePlatformError` if: * URLFetch is not available. * If you attempt to use this on App Engine Flexible, as full socket support is available. * If a request size is more than 10 megabytes. * If a response size is more than 32 megabtyes. * If you use an unsupported request method such as OPTIONS.

Follow these instructions if you would like to verify SSL certificates in Python 2. Note, the default libraries do *not* do certificate checking; you need to do additional work to validate certificates yourself. This needs the following packages installed: * pyOpenSSL (tested with 16.0.0) * cryptography (minimum 1.3.4, from pyopenssl) * idna (minimum 2.0, from cryptography) However, pyopenssl depends on cryptography, which depends on idna, so while we use all three directly here we end up having relatively few packages required. You can install them with the following command: pip install pyopenssl cryptography idna To activate certificate checking, call :func:`~urllib3.contrib.pyopenssl.inject_into_urllib3` from your Python code before you begin making HTTP requests. This can be done in a ``sitecustomize`` module, or at any other time before your application begins using ``urllib3``, like this:: try: import urllib3.contrib.pyopenssl urllib3.contrib.pyopenssl.inject_into_urllib3() except ImportError: pass Now you can use :mod:`urllib3` as you normally would, and it will support SNI when the required modules are installed. Activating this module also has the positive side effect of disabling SSL/TLS compression in Python 2 (see `CRIME attack`_). If you want to configure the default list of supported cipher suites, you can set the ``urllib3.contrib.pyopenssl.DEFAULT_SSL_CIPHER_LIST`` variable. .. _sni: https://en.wikipedia.org/wiki/Server_Name_Indication .. _crime attack: https://en.wikipedia.org/wiki/CRIME_(security_exploit) � )�absolute_importN)�x509)�backend)� _Certificate)�UnsupportedExtensionc @ s e Zd ZdS )r N)�__name__� __module__� __qualname__� r r � /usr/lib/python3.6/pyopenssl.pyr 6 s r )�timeout�error)�BytesIO)� _fileobject� )�backport_makefile)�six)�util�inject_into_urllib3�extract_from_urllib3T�PROTOCOL_TLSv1_1�TLSv1_1_METHOD�PROTOCOL_TLSv1_2�TLSv1_2_METHODc c s | ]\}}||fV qd S )Nr )�.0�k�vr r r � <genexpr>f s r i @ c C s. t � ttj_tt_ttj_dt_dtj_dS )z7Monkey-patch urllib3 with PyOpenSSL-backed SSL-support.TN)�_validate_dependencies_met�PyOpenSSLContextr �ssl_� SSLContext�HAS_SNI� IS_PYOPENSSLr r r r r s s c C s( t tj_tt_ttj_dt_dtj_dS )z4Undo monkey-patching by :func:`inject_into_urllib3`.FN)�orig_util_SSLContextr r r! �orig_util_HAS_SNIr" r# r r r r r s c C sR ddl m} t| dd�dkr$td��ddlm} |� }t|dd�dkrNtd��dS ) z{ Verifies that PyOpenSSL's package-level dependencies have been met.

Cryptography produces a dNSName as a unicode string that was idna-decoded from ASCII bytes. We need to idna-encode that string to get it back, and then on Python 3 we also need to convert to unicode via UTF-8 (the stdlib uses PyUnicode_FromStringAndSize on it, which decodes via UTF-8).

Follow these instructions if you would like to verify SSL certificates in Python 2. Note, the default libraries do *not* do certificate checking; you need to do additional work to validate certificates yourself. This needs the following packages installed: * pyOpenSSL (tested with 16.0.0) * cryptography (minimum 1.3.4, from pyopenssl) * idna (minimum 2.0, from cryptography) However, pyopenssl depends on cryptography, which depends on idna, so while we use all three directly here we end up having relatively few packages required. You can install them with the following command: pip install pyopenssl cryptography idna To activate certificate checking, call :func:`~urllib3.contrib.pyopenssl.inject_into_urllib3` from your Python code before you begin making HTTP requests. This can be done in a ``sitecustomize`` module, or at any other time before your application begins using ``urllib3``, like this:: try: import urllib3.contrib.pyopenssl urllib3.contrib.pyopenssl.inject_into_urllib3() except ImportError: pass Now you can use :mod:`urllib3` as you normally would, and it will support SNI when the required modules are installed. Activating this module also has the positive side effect of disabling SSL/TLS compression in Python 2 (see `CRIME attack`_). If you want to configure the default list of supported cipher suites, you can set the ``urllib3.contrib.pyopenssl.DEFAULT_SSL_CIPHER_LIST`` variable. .. _sni: https://en.wikipedia.org/wiki/Server_Name_Indication .. _crime attack: https://en.wikipedia.org/wiki/CRIME_(security_exploit) � )�absolute_importN)�x509)�backend)� _Certificate)�UnsupportedExtensionc @ s e Zd ZdS )r N)�__name__� __module__� __qualname__� r r � /usr/lib/python3.6/pyopenssl.pyr 6 s r )�timeout�error)�BytesIO)� _fileobject� )�backport_makefile)�six)�util�inject_into_urllib3�extract_from_urllib3T�PROTOCOL_TLSv1_1�TLSv1_1_METHOD�PROTOCOL_TLSv1_2�TLSv1_2_METHODc c s | ]\}}||fV qd S )Nr )�.0�k�vr r r � <genexpr>f s r i @ c C s. t � ttj_tt_ttj_dt_dtj_dS )z7Monkey-patch urllib3 with PyOpenSSL-backed SSL-support.TN)�_validate_dependencies_met�PyOpenSSLContextr �ssl_� SSLContext�HAS_SNI� IS_PYOPENSSLr r r r r s s c C s( t tj_tt_ttj_dt_dtj_dS )z4Undo monkey-patching by :func:`inject_into_urllib3`.FN)�orig_util_SSLContextr r r! �orig_util_HAS_SNIr" r# r r r r r s c C sR ddl m} t| dd�dkr$td��ddlm} |� }t|dd�dkrNtd��dS ) z{ Verifies that PyOpenSSL's package-level dependencies have been met.

Cryptography produces a dNSName as a unicode string that was idna-decoded from ASCII bytes. We need to idna-encode that string to get it back, and then on Python 3 we also need to convert to unicode via UTF-8 (the stdlib uses PyUnicode_FromStringAndSize on it, which decodes via UTF-8).

This makes platform-native TLS available to urllib3 users on macOS without the use of a compiler. This is an important feature because the Python Package Index is moving to become a TLSv1.2-or-higher server, and the default OpenSSL that ships with macOS is not capable of doing TLSv1.2. The only way to resolve this is to give macOS users an alternative solution to the problem, and that solution is to use SecureTransport. We use ctypes here because this solution must not require a compiler. That's because pip is not allowed to require a compiler either. This is not intended to be a seriously long-term solution to this problem. The hope is that PEP 543 will eventually solve this issue for us, at which point we can retire this contrib module. But in the short term, we need to solve the impending tire fire that is Python on Mac without this kind of contrib module. So...here we are.

Example usage:: from urllib3 import PoolManager from urllib3.contrib.appengine import AppEngineManager, is_appengine_sandbox if is_appengine_sandbox(): # AppEngineManager uses AppEngine's URLFetch API behind the scenes http = AppEngineManager() else: # PoolManager uses a socket-level API behind the scenes http = PoolManager() r = http.request('GET', 'https://google.com/') There are `limitations <https://cloud.google.com/appengine/docs/python/urlfetch/#Python_Quotas_and_limits>`_ to the URLFetch service and it may not be the best choice for your application. There are three options for using urllib3 on Google App Engine: 1. You can use :class:`AppEngineManager` with URLFetch. URLFetch is cost-effective in many circumstances as long as your usage is within the limitations. 2. You can use a normal :class:`~urllib3.PoolManager` by enabling sockets. Sockets also have `limitations and restrictions <https://cloud.google.com/appengine/docs/python/sockets/ #limitations-and-restrictions>`_ and have a lower free quota than URLFetch. To use sockets, be sure to specify the following in your ``app.yaml``:: env_variables: GAE_USE_SOCKETS_HTTPLIB : 'true' 3. If you are using `App Engine Flexible <https://cloud.google.com/appengine/docs/flexible/>`_, you can use the standard :class:`PoolManager` without any configuration or special environment variables. � )�absolute_importN� )�urljoin)� HTTPError� HTTPWarning� MaxRetryError� ProtocolError� TimeoutError�SSLError)�RequestMethods)� HTTPResponse)�Timeout)�Retry� )�_appengine_environ)�urlfetchc @ s e Zd ZdS )�AppEnginePlatformWarningN)�__name__� __module__� __qualname__� r r � /usr/lib/python3.6/appengine.pyr G s r c @ s e Zd ZdS )�AppEnginePlatformErrorN)r r r r r r r r K s r c @ sX e Zd ZdZddd�Zdd� Zdd � Zddddejfd d �Z d d � Z dd� Z dd� Z dS )�AppEngineManagera Connection manager for Google App Engine sandbox applications. This manager uses the URLFetch service directly instead of using the emulated httplib, and is subject to URLFetch limitations as described in the App Engine documentation `here <https://cloud.google.com/appengine/docs/python/urlfetch>`_. Notably it will raise an :class:`AppEnginePlatformError` if: * URLFetch is not available. * If you attempt to use this on App Engine Flexible, as full socket support is available. * If a request size is more than 10 megabytes. * If a response size is more than 32 megabtyes. * If you use an unsupported request method such as OPTIONS.

Follow these instructions if you would like to verify SSL certificates in Python 2. Note, the default libraries do *not* do certificate checking; you need to do additional work to validate certificates yourself. This needs the following packages installed: * pyOpenSSL (tested with 16.0.0) * cryptography (minimum 1.3.4, from pyopenssl) * idna (minimum 2.0, from cryptography) However, pyopenssl depends on cryptography, which depends on idna, so while we use all three directly here we end up having relatively few packages required. You can install them with the following command: pip install pyopenssl cryptography idna To activate certificate checking, call :func:`~urllib3.contrib.pyopenssl.inject_into_urllib3` from your Python code before you begin making HTTP requests. This can be done in a ``sitecustomize`` module, or at any other time before your application begins using ``urllib3``, like this:: try: import urllib3.contrib.pyopenssl urllib3.contrib.pyopenssl.inject_into_urllib3() except ImportError: pass Now you can use :mod:`urllib3` as you normally would, and it will support SNI when the required modules are installed. Activating this module also has the positive side effect of disabling SSL/TLS compression in Python 2 (see `CRIME attack`_). If you want to configure the default list of supported cipher suites, you can set the ``urllib3.contrib.pyopenssl.DEFAULT_SSL_CIPHER_LIST`` variable. .. _sni: https://en.wikipedia.org/wiki/Server_Name_Indication .. _crime attack: https://en.wikipedia.org/wiki/CRIME_(security_exploit) """ from __future__ import absolute_import import OpenSSL.SSL from cryptography import x509 from cryptography.hazmat.backends.openssl import backend as openssl_backend from cryptography.hazmat.backends.openssl.x509 import _Certificate try: from cryptography.x509 import UnsupportedExtension except ImportError: # UnsupportedExtension is gone in cryptography >= 2.1.0 class UnsupportedExtension(Exception): pass from socket import timeout, error as SocketError from io import BytesIO try: # Platform-specific: Python 2 from socket import _fileobject except ImportError: # Platform-specific: Python 3 _fileobject = None from ..packages.backports.makefile import backport_makefile import logging import ssl from ..packages import six import sys from .. import util __all__ = ['inject_into_urllib3', 'extract_from_urllib3'] # SNI always works.

Backwards-compatible to httplib's HTTPResponse but the response ``body`` is loaded and decoded on-demand when the ``data`` property is accessed. This class is also compatible with the Python standard library's :mod:`io` module, and can hence be treated as a readable object in the context of that framework. Extra parameters for behaviour not present in httplib.HTTPResponse: :param preload_content: If True, the response's body will be preloaded during construction. :param decode_content: If True, will attempt to decode the body based on the 'content-encoding' header. :param original_response: When this HTTPResponse wrapper is generated from an httplib.HTTPResponse object, it's convenient to include the original for debug purposes. It's otherwise unused. :param retries: The retries contains the last :class:`~urllib3.util.retry.Retry` that was used during the request. :param enforce_content_length: Enforce content length checking. Body returned by server must match value of Content-Length header, if present. Otherwise, raise error. rT Zdeflatei- i. i/ i3 i4 � Nr TFc C s t |t�r|| _n t|�| _|| _|| _|| _|| _|| _d| _| | _ || _ d | _ d | _ d | _ | | _d| _| | _|| _|r�t |ttf�r�|| _ | | _| | _t|d�r�|| _ d| _d | _| jjdd�j� }dd� |jd�D �}d |kr�d | _| j |�| _ t � | _ |�r | j �r | j |d �| _ d S ) NFr �readztransfer-encodingrk c s s | ]}|j � V qd S )N)rC )rD �encr r r! rQ h s z(HTTPResponse.__init__.<locals>.<genexpr>rG �chunkedT)�decode_content)!r` r �headers�status�version�reason�strictro �_has_decoded_content�retries�enforce_content_length�_decoder�_body�_fp�_original_response�_fp_bytes_read�msg� _request_url� basestringr< �_pool� _connection�hasattrrn � chunk_leftri �lowerrJ � _init_length�length_remainingrV �_decoded_bufferrl )r �bodyrp rq rr rs rt Zpreload_contentro �original_responseZpool� connectionr} rv rw �request_methodZ request_urlZtr_encrM r r r! r" ? sD zHTTPResponse.__init__c C s | j | jkr| jjd�S dS )a Should we redirect and where to? :returns: Truthy redirect location string if we got a redirect status code and valid location. ``None`` if redirect status and no location. ``False`` if not a redirect status code. �locationF)rq �REDIRECT_STATUSESrp ri )r r r r! �get_redirect_locationv s z"HTTPResponse.get_redirect_locationc C s, | j s| j rd S | j j| j� d | _d S )N)r� r� Z _put_conn)r r r r! � release_conn� s zHTTPResponse.release_connc C s" | j r | j S | jr | jdd�S d S )NT)� cache_content)ry rz rl )r r r r! r* � s zHTTPResponse.datac C s | j S )N)r� )r r r r! r� � s zHTTPResponse.connectionc C s t | j�S )N)r rz )r r r r! �isclosed� s zHTTPResponse.isclosedc C s | j S )z� Obtain the number of bytes pulled over the wire so far.

If ``block`` is set to False, more connections will be created but they will not be saved once they've been used. :param block: If set to True, no more than ``maxsize`` connections will be used at a time. When no free connections are available, the call will block until a connection has been released. This is a useful side effect for particular multithreaded situations where one does not want to use more than maxsize connections per host to prevent flooding. :param headers: Headers to include with all requests, unless other headers are given explicitly. :param retries: Retry configuration to use by default with requests in this pool. :param _proxy: Parsed proxy URL, should not be used directly, instead, see :class:`urllib3.connectionpool.ProxyManager`" :param _proxy_headers: A dictionary with proxy headers, should not be used directly, instead, see :class:`urllib3.connectionpool.ProxyManager`" :param \**conn_kw: Additional parameters are used to create fresh :class:`urllib3.connection.HTTPConnection`, :class:`urllib3.connection.HTTPSConnection` instances. �httpNFr c K s� t j| ||� tj| |� || _t|t�s4tj|�}|d krBtj}|| _ || _ | j |�| _ || _ | | _| pli | _x t|�D ]} | j jd � qzW d| _d| _| | _| jr�| jjdg � d S )Nr Zsocket_options)r) r3 r �strict� isinstancer$ � from_floatr# ZDEFAULTr �retriesr> �pool�block�proxy� proxy_headers�xrange�put�num_connections� num_requests�conn_kw� setdefault) r0 r, r/ rA r �maxsizerF �headersrD �_proxy�_proxy_headersrM �_r1 r1 r2 r3 � s( zHTTPConnectionPool.__init__c C sR | j d7 _ tjd| j | j| jp$d� | jf | j| j| jj| jd�| j ��}|S )z9 Return a fresh :class:`HTTPConnection`. r z(Starting new HTTP connection (%d): %s:%sZ80)r, r/ r rA ) rK �log�debugr, r/ � ConnectionClsr �connect_timeoutrA rM )r0 �connr1 r1 r2 � _new_conn� s z HTTPConnectionPool._new_connc C s� d}y| j j| j|d�}W nB tk r8 t| d��Y n& tjk r\ | jrXt| d��Y nX |r�t|�r�t j d| j � |j � t |dd�dkr�d}|p�| j� S ) a� Get a connection.

This is the lowest level call for making a request, so you'll need to specify all the raw details. .. note:: More commonly, it's appropriate to use a convenience method provided by :class:`.RequestMethods`, such as :meth:`request`. .. note:: `release_conn` will only behave as expected if `preload_content=False` because we want to make `preload_content=False` the default behaviour someday soon without breaking backwards compatibility. :param method: HTTP request method (such as GET, POST, PUT, etc.) :param body: Data to send in the request body (useful for creating POST requests, see HTTPConnectionPool.post_url for more convenience). :param headers: Dictionary of custom headers to send, such as User-Agent, If-None-Match, etc. If None, pool headers are used. If provided, these headers completely replace any pool-specific headers. :param retries: Configure the number of retries to allow before raising a :class:`~urllib3.exceptions.MaxRetryError` exception. Pass ``None`` to retry until you receive a response. Pass a :class:`~urllib3.util.retry.Retry` object for fine-grained control over different types of retries. Pass an integer number to retry connection errors that many times, but no other types of errors. Pass zero to never retry. If ``False``, then retries are disabled and any exception is raised immediately. Also, instead of raising a MaxRetryError on redirects, the redirect response will be returned. :type retries: :class:`~urllib3.util.retry.Retry`, False, or an int. :param redirect: If True, automatically handle redirects (status codes 301, 302, 303, 307, 308). Each redirect counts as a retry. Disabling retries will disable redirect, too. :param assert_same_host: If ``True``, will make sure that the host of the pool requests is consistent else will raise HostChangedError. When False, you can use the pool on an HTTP proxy and request foreign hosts. :param timeout: If specified, overrides the default timeout for this one request. It may be a float (in seconds) or an instance of :class:`urllib3.util.Timeout`. :param pool_timeout: If set and the pool is set to block=True, then this method will block for ``pool_timeout`` seconds and raise EmptyPoolError if no connection is available within the time period. :param release_conn: If False, then the urlopen call will not release the connection back into the pool once a response is received (but will release if you read the entire contents of the response such as when `preload_content=True`). This is useful if you're not preloading the response's content immediately. You will need to call ``r.release_conn()`` on the response ``r`` to return the connection back into the pool. If None, it takes the value of ``response_kw.get('preload_content', True)``. :param chunked: If True, urllib3 will send the body using chunked transfer encoding. Otherwise, urllib3 will send the body using the standard content-length form. Defaults to False. :param int body_pos: Position to seek to in file-like body in the event of a retry or redirect. Typically this won't need to be set because urllib3 will auto-populate the value when needed. :param \**response_kw: Additional parameters are passed to :meth:`urllib3.response.HTTPResponse.from_httplib` N)�redirect�defaultZpreload_contentTr@ F)r rn )r �bodyrP r| Zrequest_method)rE � connectionrD z"No pool connections are available.zCannot connect to proxy.zConnection aborted.� )r �_poolZ _stacktracez1Retrying (%r) after connection broken by '%r': %s)r � pool_timeout� release_conn�body_posc S sF y| j | jd� W n. ttttttfk r@ } zW Y d d }~X nX d S )N)Zdecode_content)�readZ_has_decoded_contentr r rw r r r )�responser~ r1 r1 r2 �drain_and_release_conn� s z:HTTPConnectionPool.urlopen.<locals>.drain_and_release_conni/ ZGET)r� r� zRedirecting %s -> %s)rD r� �assert_same_hostr r� r� r� z Retry-Afterz Retry: %s)8rP rB r# Zfrom_intrD rZ r� r r+ �copy�updaterH r! rd r^ rW r rG r] rb r� � ResponseClsZ from_httplibr r\ r r r rw r r r r r r Z increment�sysrp Zsleepr8 r` rT r_ �urlopenZget_redirect_locationrx r Z_prepare_for_method_changer Zraise_on_redirectZsleep_for_retryrU �boolZ getheaderZis_retryZraise_on_status)r0 r{ rk r� rP rD r� r� r r� r� r| r� Z response_kwrX Zrelease_this_connrj Z clean_exitr} Zis_new_proxy_connr Z response_connr� r~ r� Zredirect_locationZhas_retry_afterr1 r1 r2 r� � s� ^ zHTTPConnectionPool.urlopen)N)r5 r; r< r= r+ r rV r r� r$ rs r3 rY r^ r` ra rb rd rm rc r� rz r8 r� r� r1 r1 r1 r2 r? ` s. :% & Ur? c sn e Zd ZdZdZeZddejddddddddddddddfdd�Z dd � Z d d � Z d d � Z � fdd�Z � ZS )�HTTPSConnectionPoola� Same as :class:`.HTTPConnectionPool`, but HTTPS. When Python is compiled with the :mod:`ssl` module, then :class:`.VerifiedHTTPSConnection` is used, which *can* verify certificates, instead of :class:`.HTTPSConnection`. :class:`.VerifiedHTTPSConnection` uses one of ``assert_fingerprint``, ``assert_hostname`` and ``host`` in this order to verify connections. If ``assert_hostname`` is False, no verification is done. The ``key_file``, ``cert_file``, ``cert_reqs``, ``ca_certs``, ``ca_cert_dir``, and ``ssl_version`` are only used if :mod:`ssl` is available and are fed into :meth:`urllib3.util.ssl_wrap_socket` to upgrade the connection socket into an SSL socket. �httpsNFr c K sf t j| ||||||||| | f |� |r2| d kr2d} | | _| | _| | _|| _|| _|| _|| _|| _ d S )NZ CERT_REQUIRED) r? r3 �key_file� cert_file� cert_reqs�ca_certs� ca_cert_dir� ssl_version�assert_hostname�assert_fingerprint)r0 r, r/ rA r rO rF rP rD rQ rR r� r� r� r� r� r� r� r� rM r1 r1 r2 r3 � s z HTTPSConnectionPool.__init__c C s< t |t�r8|j| j| j| j| j| j| j| j d� | j |_ |S )z� Prepare the ``connection`` for :meth:`urllib3.util.ssl_wrap_socket` and establish the tunnel if proxy is used. )r� r� r� r� r� r� r� ) rB r Zset_certr� r� r� r� r� r� r� r� )r0 rX r1 r1 r2 � _prepare_conn s z!HTTPSConnectionPool._prepare_connc C s |j | j| j| j� |j� dS )z� Establish tunnel connection early, because otherwise httplib would improperly set Host: header to proxy's IP:port.

Provides behavior for making common types of HTTP request methods and decides which type of request field encoding to use. Specifically, :meth:`.request_encode_url` is for sending requests whose fields are encoded in the URL (such as GET, HEAD, DELETE). :meth:`.request_encode_body` is for sending requests whose fields are encoded in the *body* of the request using multipart or www-form-urlencoded (such as for POST, PUT, PATCH). :meth:`.request` is for making any kind of request, it will look up the appropriate encoding format and use one of the above two methods to make the request. Initializer parameters: :param headers: Headers to include with all requests, unless other headers are given explicitly.

This is a convenience method that requires the least amount of manual effort.

This is useful for request methods like POST, PUT, PATCH, etc. When ``encode_multipart=True`` (default), then :meth:`urllib3.filepost.encode_multipart_formdata` is used to encode the payload with the appropriate content type. Otherwise :meth:`urllib.urlencode` is used with the 'application/x-www-form-urlencoded' content type. Multipart encoding must be used when posting files, and it's reasonably safe to use it in other times too. However, it may break request signing, such as with OAuth. Supports an optional ``fields`` parameter of key/value strings AND key/filetuple. A filetuple is a (filename, data, MIME type) tuple where the MIME type is optional. For example:: fields = { 'foo': 'bar', 'fakefile': ('foofile.txt', 'contents of foofile'), 'realfile': ('barfile.txt', open('realfile').read()), 'typedfile': ('bazfile.bin', open('bazfile').read(), 'image/jpeg'), 'nonamefile': 'contents of nonamefile field', } When uploading a file, providing a filename (the first parameter of the tuple) is optional but recommended to best mimic behavior of browsers. Note that if ``headers`` are supplied, the 'Content-Type' header will be overwritten because it depends on the dynamic random boundary string which is used to compose the body of the request. The random boundary string can be explicitly set with the ``multipart_boundary`` parameter. Nr r zFrequest got values for both 'fields' and 'body', can only specify one.)�boundaryz!application/x-www-form-urlencodedz Content-Type)r � TypeErrorr r r r ) r r r r r r r r r r Z content_typer r r r [ s & z"RequestMethods.request_encode_body)N)NNTN)NN)NN)NNTN) �__name__� __module__� __qualname__�__doc__r r r r r r r r r r r s N) Z __future__r Zfilepostr Z packages.six.moves.urllib.parser �__all__�objectr r r r r �<module> s site-packages/urllib3/__pycache__/_collections.cpython-36.pyc 0000644 00000025561 15152656750 0020200 0 ustar 00 3 ��yi+, � @ s� d dl mZ yd dlmZmZ W n$ ek rD d dlmZmZ Y nX yd dlmZ W n" ek rx G dd� d�ZY nX d dlm Z ddl m Z dd l m Z mZmZ d d gZe� ZG d d � d e�ZG d d � d e�ZdS )� )�absolute_import)�Mapping�MutableMapping)�RLockc @ s e Zd Zdd� Zdd� ZdS )r c C s d S )N� )�selfr r �"/usr/lib/python3.6/_collections.py� __enter__ s zRLock.__enter__c C s d S )Nr )r �exc_type� exc_value� tracebackr r r �__exit__ s zRLock.__exit__N)�__name__� __module__� __qualname__r r r r r r r s r )� OrderedDict� )� InvalidHeader)�iterkeys� itervalues�PY3�RecentlyUsedContainer�HTTPHeaderDictc @ sV e Zd ZdZeZddd�Zdd� Zdd � Zd d � Z d d � Z dd� Z dd� Z dd� Z dS )r a� Provides a thread-safe dict-like container which maintains up to ``maxsize`` keys while throwing away the least-recently-used keys beyond ``maxsize``. :param maxsize: Maximum number of recent elements to retain. :param dispose_func: Every time an item is evicted from the container, ``dispose_func(value)`` is called.

Backwards-compatible to httplib's HTTPResponse but the response ``body`` is loaded and decoded on-demand when the ``data`` property is accessed. This class is also compatible with the Python standard library's :mod:`io` module, and can hence be treated as a readable object in the context of that framework. Extra parameters for behaviour not present in httplib.HTTPResponse: :param preload_content: If True, the response's body will be preloaded during construction. :param decode_content: If True, will attempt to decode the body based on the 'content-encoding' header. :param original_response: When this HTTPResponse wrapper is generated from an httplib.HTTPResponse object, it's convenient to include the original for debug purposes. It's otherwise unused. :param retries: The retries contains the last :class:`~urllib3.util.retry.Retry` that was used during the request. :param enforce_content_length: Enforce content length checking. Body returned by server must match value of Content-Length header, if present. Otherwise, raise error. rT Zdeflatei- i. i/ i3 i4 � Nr TFc C s t |t�r|| _n t|�| _|| _|| _|| _|| _|| _d| _| | _ || _ d | _ d | _ d | _ | | _d| _| | _|| _|r�t |ttf�r�|| _ | | _| | _t|d�r�|| _ d| _d | _| jjdd�j� }dd� |jd�D �}d |kr�d | _| j |�| _ t � | _ |�r | j �r | j |d �| _ d S ) NFr �readztransfer-encodingrk c s s | ]}|j � V qd S )N)rC )rD �encr r r! rQ h s z(HTTPResponse.__init__.<locals>.<genexpr>rG �chunkedT)�decode_content)!r` r �headers�status�version�reason�strictro �_has_decoded_content�retries�enforce_content_length�_decoder�_body�_fp�_original_response�_fp_bytes_read�msg� _request_url� basestringr< �_pool� _connection�hasattrrn � chunk_leftri �lowerrJ � _init_length�length_remainingrV �_decoded_bufferrl )r �bodyrp rq rr rs rt Zpreload_contentro �original_responseZpool� connectionr} rv rw �request_methodZ request_urlZtr_encrM r r r! r" ? sD zHTTPResponse.__init__c C s | j | jkr| jjd�S dS )a Should we redirect and where to? :returns: Truthy redirect location string if we got a redirect status code and valid location. ``None`` if redirect status and no location. ``False`` if not a redirect status code. �locationF)rq �REDIRECT_STATUSESrp ri )r r r r! �get_redirect_locationv s z"HTTPResponse.get_redirect_locationc C s, | j s| j rd S | j j| j� d | _d S )N)r� r� Z _put_conn)r r r r! � release_conn� s zHTTPResponse.release_connc C s" | j r | j S | jr | jdd�S d S )NT)� cache_content)ry rz rl )r r r r! r* � s zHTTPResponse.datac C s | j S )N)r� )r r r r! r� � s zHTTPResponse.connectionc C s t | j�S )N)r rz )r r r r! �isclosed� s zHTTPResponse.isclosedc C s | j S )z� Obtain the number of bytes pulled over the wire so far.

This parameter is ignored in Python 3. :param timeout: Socket timeout in seconds for each individual connection. This can be a float or integer, which sets the timeout for the HTTP request, or an instance of :class:`urllib3.util.Timeout` which gives you more fine-grained control over request timeouts. After the constructor has been parsed, this is always a `urllib3.util.Timeout` object. :param maxsize: Number of connections to save that can be reused. More than 1 is useful in multithreaded situations. If ``block`` is set to False, more connections will be created but they will not be saved once they've been used. :param block: If set to True, no more than ``maxsize`` connections will be used at a time. When no free connections are available, the call will block until a connection has been released. This is a useful side effect for particular multithreaded situations where one does not want to use more than maxsize connections per host to prevent flooding. :param headers: Headers to include with all requests, unless other headers are given explicitly. :param retries: Retry configuration to use by default with requests in this pool. :param _proxy: Parsed proxy URL, should not be used directly, instead, see :class:`urllib3.connectionpool.ProxyManager`" :param _proxy_headers: A dictionary with proxy headers, should not be used directly, instead, see :class:`urllib3.connectionpool.ProxyManager`" :param \**conn_kw: Additional parameters are used to create fresh :class:`urllib3.connection.HTTPConnection`, :class:`urllib3.connection.HTTPSConnection` instances. �httpNFr c K s� t j| ||� tj| |� || _t|t�s4tj|�}|d krBtj}|| _ || _ | j |�| _ || _ | | _| pli | _x t|�D ]} | j jd � qzW d| _d| _| | _| jr�| jjdg � d S )Nr Zsocket_options)r) r3 r �strict� isinstancer$ � from_floatr# ZDEFAULTr �retriesr> �pool�block�proxy� proxy_headers�xrange�put�num_connections� num_requests�conn_kw� setdefault) r0 r, r/ rA r �maxsizerF �headersrD �_proxy�_proxy_headersrM �_r1 r1 r2 r3 � s( zHTTPConnectionPool.__init__c C sR | j d7 _ tjd| j | j| jp$d� | jf | j| j| jj| jd�| j ��}|S )z9 Return a fresh :class:`HTTPConnection`. r z(Starting new HTTP connection (%d): %s:%sZ80)r, r/ r rA ) rK �log�debugr, r/ � ConnectionClsr �connect_timeoutrA rM )r0 �connr1 r1 r2 � _new_conn� s z HTTPConnectionPool._new_connc C s� d}y| j j| j|d�}W nB tk r8 t| d��Y n& tjk r\ | jrXt| d��Y nX |r�t|�r�t j d| j � |j � t |dd�dkr�d}|p�| j� S ) a� Get a connection.

This is the lowest level call for making a request, so you'll need to specify all the raw details. .. note:: More commonly, it's appropriate to use a convenience method provided by :class:`.RequestMethods`, such as :meth:`request`. .. note:: `release_conn` will only behave as expected if `preload_content=False` because we want to make `preload_content=False` the default behaviour someday soon without breaking backwards compatibility. :param method: HTTP request method (such as GET, POST, PUT, etc.) :param body: Data to send in the request body (useful for creating POST requests, see HTTPConnectionPool.post_url for more convenience). :param headers: Dictionary of custom headers to send, such as User-Agent, If-None-Match, etc. If None, pool headers are used. If provided, these headers completely replace any pool-specific headers. :param retries: Configure the number of retries to allow before raising a :class:`~urllib3.exceptions.MaxRetryError` exception. Pass ``None`` to retry until you receive a response. Pass a :class:`~urllib3.util.retry.Retry` object for fine-grained control over different types of retries. Pass an integer number to retry connection errors that many times, but no other types of errors. Pass zero to never retry. If ``False``, then retries are disabled and any exception is raised immediately. Also, instead of raising a MaxRetryError on redirects, the redirect response will be returned. :type retries: :class:`~urllib3.util.retry.Retry`, False, or an int. :param redirect: If True, automatically handle redirects (status codes 301, 302, 303, 307, 308). Each redirect counts as a retry. Disabling retries will disable redirect, too. :param assert_same_host: If ``True``, will make sure that the host of the pool requests is consistent else will raise HostChangedError. When False, you can use the pool on an HTTP proxy and request foreign hosts. :param timeout: If specified, overrides the default timeout for this one request. It may be a float (in seconds) or an instance of :class:`urllib3.util.Timeout`. :param pool_timeout: If set and the pool is set to block=True, then this method will block for ``pool_timeout`` seconds and raise EmptyPoolError if no connection is available within the time period. :param release_conn: If False, then the urlopen call will not release the connection back into the pool once a response is received (but will release if you read the entire contents of the response such as when `preload_content=True`). This is useful if you're not preloading the response's content immediately. You will need to call ``r.release_conn()`` on the response ``r`` to return the connection back into the pool. If None, it takes the value of ``response_kw.get('preload_content', True)``. :param chunked: If True, urllib3 will send the body using chunked transfer encoding. Otherwise, urllib3 will send the body using the standard content-length form. Defaults to False. :param int body_pos: Position to seek to in file-like body in the event of a retry or redirect. Typically this won't need to be set because urllib3 will auto-populate the value when needed. :param \**response_kw: Additional parameters are passed to :meth:`urllib3.response.HTTPResponse.from_httplib` N)�redirect�defaultZpreload_contentTr@ F)r rn )r �bodyrP r| Zrequest_method)rE � connectionrD z"No pool connections are available.zCannot connect to proxy.zConnection aborted.� )r �_poolZ _stacktracez1Retrying (%r) after connection broken by '%r': %s)r � pool_timeout� release_conn�body_posc S sF y| j | jd� W n. ttttttfk r@ } zW Y d d }~X nX d S )N)Zdecode_content)�readZ_has_decoded_contentr r rw r r r )�responser~ r1 r1 r2 �drain_and_release_conn� s z:HTTPConnectionPool.urlopen.<locals>.drain_and_release_conni/ ZGET)r� r� zRedirecting %s -> %s)rD r� �assert_same_hostr r� r� r� z Retry-Afterz Retry: %s)8rP rB r# Zfrom_intrD rZ r� r r+ �copy�updaterH r! rd r^ rW r rG r] rb r� � ResponseClsZ from_httplibr r\ r r r rw r r r r r r Z increment�sysrp Zsleepr8 r` rT r_ �urlopenZget_redirect_locationrx r Z_prepare_for_method_changer Zraise_on_redirectZsleep_for_retryrU �boolZ getheaderZis_retryZraise_on_status)r0 r{ rk r� rP rD r� r� r r� r� r| r� Z response_kwrX Zrelease_this_connrj Z clean_exitr} Zis_new_proxy_connr Z response_connr� r~ r� Zredirect_locationZhas_retry_afterr1 r1 r2 r� � s� ^ zHTTPConnectionPool.urlopen)N)r5 r; r< r= r+ r rV r r� r$ rs r3 rY r^ r` ra rb rd rm rc r� rz r8 r� r� r1 r1 r1 r2 r? ` s. :% & Ur? c sn e Zd ZdZdZeZddejddddddddddddddfdd�Z dd � Z d d � Z d d � Z � fdd�Z � ZS )�HTTPSConnectionPoola� Same as :class:`.HTTPConnectionPool`, but HTTPS. When Python is compiled with the :mod:`ssl` module, then :class:`.VerifiedHTTPSConnection` is used, which *can* verify certificates, instead of :class:`.HTTPSConnection`. :class:`.VerifiedHTTPSConnection` uses one of ``assert_fingerprint``, ``assert_hostname`` and ``host`` in this order to verify connections. If ``assert_hostname`` is False, no verification is done. The ``key_file``, ``cert_file``, ``cert_reqs``, ``ca_certs``, ``ca_cert_dir``, and ``ssl_version`` are only used if :mod:`ssl` is available and are fed into :meth:`urllib3.util.ssl_wrap_socket` to upgrade the connection socket into an SSL socket. �httpsNFr c K sf t j| ||||||||| | f |� |r2| d kr2d} | | _| | _| | _|| _|| _|| _|| _|| _ d S )NZ CERT_REQUIRED) r? r3 �key_file� cert_file� cert_reqs�ca_certs� ca_cert_dir� ssl_version�assert_hostname�assert_fingerprint)r0 r, r/ rA r rO rF rP rD rQ rR r� r� r� r� r� r� r� r� rM r1 r1 r2 r3 � s z HTTPSConnectionPool.__init__c C s< t |t�r8|j| j| j| j| j| j| j| j d� | j |_ |S )z� Prepare the ``connection`` for :meth:`urllib3.util.ssl_wrap_socket` and establish the tunnel if proxy is used. )r� r� r� r� r� r� r� ) rB r Zset_certr� r� r� r� r� r� r� r� )r0 rX r1 r1 r2 � _prepare_conn s z!HTTPSConnectionPool._prepare_connc C s |j | j| j| j� |j� dS )z� Establish tunnel connection early, because otherwise httplib would improperly set Host: header to proxy's IP:port.

Provides behavior for making common types of HTTP request methods and decides which type of request field encoding to use. Specifically, :meth:`.request_encode_url` is for sending requests whose fields are encoded in the URL (such as GET, HEAD, DELETE). :meth:`.request_encode_body` is for sending requests whose fields are encoded in the *body* of the request using multipart or www-form-urlencoded (such as for POST, PUT, PATCH). :meth:`.request` is for making any kind of request, it will look up the appropriate encoding format and use one of the above two methods to make the request.

This is a convenience method that requires the least amount of manual effort.

This is useful for request methods like POST, PUT, PATCH, etc. When ``encode_multipart=True`` (default), then :meth:`urllib3.filepost.encode_multipart_formdata` is used to encode the payload with the appropriate content type. Otherwise :meth:`urllib.urlencode` is used with the 'application/x-www-form-urlencoded' content type. Multipart encoding must be used when posting files, and it's reasonably safe to use it in other times too. However, it may break request signing, such as with OAuth. Supports an optional ``fields`` parameter of key/value strings AND key/filetuple. A filetuple is a (filename, data, MIME type) tuple where the MIME type is optional. For example:: fields = { 'foo': 'bar', 'fakefile': ('foofile.txt', 'contents of foofile'), 'realfile': ('barfile.txt', open('realfile').read()), 'typedfile': ('bazfile.bin', open('bazfile').read(), 'image/jpeg'), 'nonamefile': 'contents of nonamefile field', } When uploading a file, providing a filename (the first parameter of the tuple) is optional but recommended to best mimic behavior of browsers. Note that if ``headers`` are supplied, the 'Content-Type' header will be overwritten because it depends on the dynamic random boundary string which is used to compose the body of the request. The random boundary string can be explicitly set with the ``multipart_boundary`` parameter.

Each retry attempt will create a new Retry object with updated values, so they can be safely reused. Retries can be defined as a default for a pool:: retries = Retry(connect=5, read=2, redirect=5) http = PoolManager(retries=retries) response = http.request('GET', 'http://example.com/') Or per-request (which overrides the default for the pool):: response = http.request('GET', 'http://example.com/', retries=Retry(10)) Retries can be disabled by passing ``False``:: response = http.request('GET', 'http://example.com/', retries=False) Errors will be wrapped in :class:`~urllib3.exceptions.MaxRetryError` unless retries are disabled, in which case the causing exception will be raised. :param int total: Total number of retries to allow. Takes precedence over other counts. Set to ``None`` to remove this constraint and fall back on other counts. It's a good idea to set this to some sensibly-high value to account for unexpected edge cases and avoid infinite retry loops. Set to ``0`` to fail on the first retry. Set to ``False`` to disable and imply ``raise_on_redirect=False``. :param int connect: How many connection-related errors to retry on. These are errors raised before the request is sent to the remote server, which we assume has not triggered the server to process the request. Set to ``0`` to fail on the first retry of this type. :param int read: How many times to retry on read errors. These errors are raised after the request was sent to the server, so the request may have side-effects. Set to ``0`` to fail on the first retry of this type. :param int redirect: How many redirects to perform. Limit this to avoid infinite redirect loops. A redirect is a HTTP response with a status code 301, 302, 303, 307 or 308. Set to ``0`` to fail on the first retry of this type. Set to ``False`` to disable and imply ``raise_on_redirect=False``. :param int status: How many times to retry on bad status codes. These are retries made on responses, where status code matches ``status_forcelist``. Set to ``0`` to fail on the first retry of this type. :param iterable method_whitelist: Set of uppercased HTTP method verbs that we should retry on. By default, we only retry on methods which are considered to be idempotent (multiple requests with the same parameters end with the same state). See :attr:`Retry.DEFAULT_METHOD_WHITELIST`. Set to a ``False`` value to retry on any verb. :param iterable status_forcelist: A set of integer HTTP status codes that we should force a retry on. A retry is initiated if the request method is in ``method_whitelist`` and the response status code is in ``status_forcelist``. By default, this is disabled with ``None``. :param float backoff_factor: A backoff factor to apply between attempts after the second try (most errors are resolved immediately by a second try without a delay). urllib3 will sleep for:: {backoff factor} * (2 ** ({number of total retries} - 1)) seconds. If the backoff_factor is 0.1, then :func:`.sleep` will sleep for [0.0s, 0.2s, 0.4s, ...] between retries. It will never be longer than :attr:`Retry.BACKOFF_MAX`. By default, backoff is disabled (set to 0). :param bool raise_on_redirect: Whether, if the number of redirects is exhausted, to raise a MaxRetryError, or to return a response with a response code in the 3xx range. :param bool raise_on_status: Similar meaning to ``raise_on_redirect``: whether we should raise an exception, or return a response, if status falls in ``status_forcelist`` range and retries have been exhausted. :param tuple history: The history of the request encountered during each call to :meth:`~Retry.increment`. The list is in the order the requests occurred. Each list item is of class :class:`RequestHistory`. :param bool respect_retry_after_header: Whether to respect Retry-After header on status codes defined as :attr:`Retry.RETRY_AFTER_STATUS_CODES` or not. :param iterable remove_headers_on_redirect: Sequence of headers to remove from the request when a response indicating a redirect is returned before firing off the redirected request.

This will default to PROTOCOL_SSLv23 which will negotiate the highest protocol that both the server and your installation of OpenSSL support. :param cert_reqs: Whether to require the certificate verification.

Each retry attempt will create a new Retry object with updated values, so they can be safely reused. Retries can be defined as a default for a pool:: retries = Retry(connect=5, read=2, redirect=5) http = PoolManager(retries=retries) response = http.request('GET', 'http://example.com/') Or per-request (which overrides the default for the pool):: response = http.request('GET', 'http://example.com/', retries=Retry(10)) Retries can be disabled by passing ``False``:: response = http.request('GET', 'http://example.com/', retries=False) Errors will be wrapped in :class:`~urllib3.exceptions.MaxRetryError` unless retries are disabled, in which case the causing exception will be raised. :param int total: Total number of retries to allow. Takes precedence over other counts. Set to ``None`` to remove this constraint and fall back on other counts. It's a good idea to set this to some sensibly-high value to account for unexpected edge cases and avoid infinite retry loops. Set to ``0`` to fail on the first retry. Set to ``False`` to disable and imply ``raise_on_redirect=False``. :param int connect: How many connection-related errors to retry on. These are errors raised before the request is sent to the remote server, which we assume has not triggered the server to process the request. Set to ``0`` to fail on the first retry of this type. :param int read: How many times to retry on read errors. These errors are raised after the request was sent to the server, so the request may have side-effects. Set to ``0`` to fail on the first retry of this type. :param int redirect: How many redirects to perform. Limit this to avoid infinite redirect loops. A redirect is a HTTP response with a status code 301, 302, 303, 307 or 308. Set to ``0`` to fail on the first retry of this type. Set to ``False`` to disable and imply ``raise_on_redirect=False``. :param int status: How many times to retry on bad status codes. These are retries made on responses, where status code matches ``status_forcelist``. Set to ``0`` to fail on the first retry of this type. :param iterable method_whitelist: Set of uppercased HTTP method verbs that we should retry on. By default, we only retry on methods which are considered to be idempotent (multiple requests with the same parameters end with the same state). See :attr:`Retry.DEFAULT_METHOD_WHITELIST`.

A retry is initiated if the request method is in ``method_whitelist`` and the response status code is in ``status_forcelist``. By default, this is disabled with ``None``. :param float backoff_factor: A backoff factor to apply between attempts after the second try (most errors are resolved immediately by a second try without a delay). urllib3 will sleep for:: {backoff factor} * (2 ** ({number of total retries} - 1)) seconds.

By default, backoff is disabled (set to 0). :param bool raise_on_redirect: Whether, if the number of redirects is exhausted, to raise a MaxRetryError, or to return a response with a response code in the 3xx range. :param bool raise_on_status: Similar meaning to ``raise_on_redirect``: whether we should raise an exception, or return a response, if status falls in ``status_forcelist`` range and retries have been exhausted. :param tuple history: The history of the request encountered during each call to :meth:`~Retry.increment`. The list is in the order the requests occurred. Each list item is of class :class:`RequestHistory`. :param bool respect_retry_after_header: Whether to respect Retry-After header on status codes defined as :attr:`Retry.RETRY_AFTER_STATUS_CODES` or not. :param iterable remove_headers_on_redirect: Sequence of headers to remove from the request when a response indicating a redirect is returned before firing off the redirected request.

Much of the Python ecosystem already uses urllib3 and you should too. urllib3 brings many critical features that are missing from the Python standard libraries: - Thread safety. - Connection pooling. - Client-side SSL/TLS verification. - File uploads with multipart encoding. - Helpers for retrying requests and dealing with HTTP redirects. - Support for gzip and deflate encoding. - Proxy support for HTTP and SOCKS. - 100% test coverage. urllib3 is powerful and easy to use:: >>> import urllib3 >>> http = urllib3.PoolManager() >>> r = http.request('GET', 'http://httpbin.org/robots.txt') >>> r.status 200 >>> r.data 'User-agent: *\nDisallow: /deny\n' Installing ---------- urllib3 can be installed with `pip <https://pip.pypa.io>`_:: $ pip install urllib3 Alternatively, you can grab the latest source code from `GitHub <https://github.com/urllib3/urllib3>`_:: $ git clone git://github.com/urllib3/urllib3.git $ python setup.py install Documentation ------------- urllib3 has usage and reference documentation at `urllib3.readthedocs.io <https://urllib3.readthedocs.io>`_.

Reading small chunks of compressed data is safer and much more efficient now. - Fixed a high-severity security issue where decompression-bomb safeguards of the streaming API were bypassed when HTTP redirects were followed.

(Pull #1016) * Add retry counter for ``status_forcelist``. (Issue #1147) * Added ``contrib`` module for using SecureTransport on macOS: ``urllib3.contrib.securetransport``. (Pull #1122) * urllib3 now only normalizes the case of ``http://`` and ``https://`` schemes: for schemes it does not recognise, it assumes they are case-sensitive and leaves them unchanged. (Issue #1080) 1.20 (2017-01-19) ----------------- * Added support for waiting for I/O using selectors other than select, improving urllib3's behaviour with large numbers of concurrent connections. (Pull #1001) * Updated the date for the system clock check. (Issue #1005) * ConnectionPools now correctly consider hostnames to be case-insensitive. (Issue #1032) * Outdated versions of PyOpenSSL now cause the PyOpenSSL contrib module to fail when it is injected, rather than at first use. (Pull #1063) * Outdated versions of cryptography now cause the PyOpenSSL contrib module to fail when it is injected, rather than at first use.

(Issue #1009) 1.18.1 (2016-10-27) ------------------- * CVE-2016-9015. Users who are using urllib3 version 1.17 or 1.18 along with PyOpenSSL injection and OpenSSL 1.1.0 *must* upgrade to this version. This release fixes a vulnerability whereby urllib3 in the above configuration would silently fail to validate TLS certificates due to erroneously setting invalid flags in OpenSSL's ``SSL_CTX_set_verify`` function. These erroneous flags do not cause a problem in OpenSSL versions before 1.1.0, which interprets the presence of any flag as requesting certificate validation. There is no PR for this patch, as it was prepared for simultaneous disclosure and release. The master branch received the same fix in PR #1010. 1.18 (2016-09-26) ----------------- * Fixed incorrect message for IncompleteRead exception. (PR #973) * Accept ``iPAddress`` subject alternative name fields in TLS certificates. (Issue #258) * Fixed consistency of ``HTTPResponse.closed`` between Python 2 and 3. (Issue #977) * Fixed handling of wildcard certificates when using PyOpenSSL. (Issue #979) 1.17 (2016-09-06) ----------------- * Accept ``SSLContext`` objects for use in SSL/TLS negotiation. (Issue #835) * ConnectionPool debug log now includes scheme, host, and port. (Issue #897) * Substantially refactored documentation. (Issue #887) * Used URLFetch default timeout on AppEngine, rather than hardcoding our own. (Issue #858) * Normalize the scheme and host in the URL parser (Issue #833) * ``HTTPResponse`` contains the last ``Retry`` object, which now also contains retries history. (Issue #848) * Timeout can no longer be set as boolean, and must be greater than zero. (PR #924) * Removed pyasn1 and ndg-httpsclient from dependencies used for PyOpenSSL. We now use cryptography and idna, both of which are already dependencies of PyOpenSSL. (PR #930) * Fixed infinite loop in ``stream`` when amt=None. (Issue #928) * Try to use the operating system's certificates when we are using an ``SSLContext``. (PR #941) * Updated cipher suite list to allow ChaCha20+Poly1305. AES-GCM is preferred to ChaCha20, but ChaCha20 is then preferred to everything else. (PR #947) * Updated cipher suite list to remove 3DES-based cipher suites. (PR #958) * Removed the cipher suite fallback to allow HIGH ciphers. (PR #958) * Implemented ``length_remaining`` to determine remaining content to be read. (PR #949) * Implemented ``enforce_content_length`` to enable exceptions when incomplete data chunks are received. (PR #949) * Dropped connection start, dropped connection reset, redirect, forced retry, and new HTTPS connection log levels to DEBUG, from INFO. (PR #967) 1.16 (2016-06-11) ----------------- * Disable IPv6 DNS when IPv6 connections are not possible. (Issue #840) * Provide ``key_fn_by_scheme`` pool keying mechanism that can be overridden. (Issue #830) * Normalize scheme and host to lowercase for pool keys, and include ``source_address``. (Issue #830) * Cleaner exception chain in Python 3 for ``_make_request``. (Issue #861) * Fixed installing ``urllib3[socks]`` extra. (Issue #864) * Fixed signature of ``ConnectionPool.close`` so it can actually safely be called by subclasses. (Issue #873) * Retain ``release_conn`` state across retries. (Issues #651, #866) * Add customizable ``HTTPConnectionPool.ResponseCls``, which defaults to ``HTTPResponse`` but can be replaced with a subclass. (Issue #879) 1.15.1 (2016-04-11) ------------------- * Fix packaging to include backports module. (Issue #841) 1.15 (2016-04-06) ----------------- * Added Retry(raise_on_status=False). (Issue #720) * Always use setuptools, no more distutils fallback. (Issue #785) * Dropped support for Python 3.2. (Issue #786) * Chunked transfer encoding when requesting with ``chunked=True``. (Issue #790) * Fixed regression with IPv6 port parsing. (Issue #801) * Append SNIMissingWarning messages to allow users to specify it in the PYTHONWARNINGS environment variable. (Issue #816) * Handle unicode headers in Py2. (Issue #818) * Log certificate when there is a hostname mismatch. (Issue #820) * Preserve order of request/response headers. (Issue #821) 1.14 (2015-12-29) ----------------- * contrib: SOCKS proxy support! (Issue #762) * Fixed AppEngine handling of transfer-encoding header and bug in Timeout defaults checking.

(Issue #734) * Adjusted ``read_chunked`` to handle gzipped, chunk-encoded bodies without repeatedly flushing the decoder, to function better on Jython. (Issue #743) * Accept ``ca_cert_dir`` for SSL-related PoolManager configuration. (Issue #758) 1.12 (2015-09-03) ----------------- * Rely on ``six`` for importing ``httplib`` to work around conflicts with other Python 3 shims. (Issue #688) * Add support for directories of certificate authorities, as supported by OpenSSL. (Issue #701) * New exception: ``NewConnectionError``, raised when we fail to establish a new connection, usually ``ECONNREFUSED`` socket error. 1.11 (2015-07-21) ----------------- * When ``ca_certs`` is given, ``cert_reqs`` defaults to ``'CERT_REQUIRED'``. (Issue #650) * ``pip install urllib3[secure]`` will install Certifi and PyOpenSSL as dependencies. (Issue #678) * Made ``HTTPHeaderDict`` usable as a ``headers`` input value (Issues #632, #679) * Added `urllib3.contrib.appengine <https://urllib3.readthedocs.io/en/latest/contrib.html#google-app-engine>`_ which has an ``AppEngineManager`` for using ``URLFetch`` in a Google AppEngine environment.

(Issue #289) * Expand default-port comparison in ``HTTPConnectionPool.is_same_host`` to allow a pool with no specified port to be considered equal to to an HTTP/HTTPS url with port 80/443 explicitly provided. (Issue #305) * Improved default SSL/TLS settings to avoid vulnerabilities. (Issue #309) * Fixed ``urllib3.poolmanager.ProxyManager`` not retrying on connect errors. (Issue #310) * Disable Nagle's Algorithm on the socket for non-proxies. A subset of requests will send the entire HTTP request ~200 milliseconds faster; however, some of the resulting TCP packets will be smaller. (Issue #254) * Increased maximum number of SubjectAltNames in ``urllib3.contrib.pyopenssl`` from the default 64 to 1024 in a single certificate. (Issue #318) * Headers are now passed and stored as a custom ``urllib3.collections_.HTTPHeaderDict`` object rather than a plain ``dict``. (Issue #329, #333) * Headers no longer lose their case on Python 3. (Issue #236) * ``urllib3.contrib.pyopenssl`` now uses the operating system's default CA certificates on inject. (Issue #332) * Requests with ``retries=False`` will immediately raise any exceptions without wrapping them in ``MaxRetryError``. (Issue #348) * Fixed open socket leak with SSL-related failures.

(Issue #178) * Support for relative urls in ``Location: ...`` header. (Issue #179) * ``urllib3.response.HTTPResponse`` now inherits from ``io.IOBase`` for bonus file-like functionality. (Issue #187) * Passing ``assert_hostname=False`` when creating a HTTPSConnectionPool will skip hostname verification for SSL connections. (Issue #194) * New method ``urllib3.response.HTTPResponse.stream(...)`` which acts as a generator wrapped around ``.read(...)``. (Issue #198) * IPv6 url parsing enforces brackets around the hostname. (Issue #199) * Fixed thread race condition in ``urllib3.poolmanager.PoolManager.connection_from_host(...)`` (Issue #204) * ``ProxyManager`` requests now include non-default port in ``Host: ...`` header.

(Issue #203) 1.6 (2013-04-25) ---------------- * Contrib: Optional SNI support for Py2 using PyOpenSSL. (Issue #156) * ``ProxyManager`` automatically adds ``Host: ...`` header if not given. * Improved SSL-related code. ``cert_req`` now optionally takes a string like "REQUIRED" or "NONE". Same with ``ssl_version`` takes strings like "SSLv23" The string values reflect the suffix of the respective constant variable. (Issue #130) * Vendored ``socksipy`` now based on Anorov's fork which handles unexpectedly closed proxy connections and larger read buffers. (Issue #135) * Ensure the connection is closed if no data is received, fixes connection leak on some platforms. (Issue #133) * Added SNI support for SSL/TLS connections on Py32+. (Issue #89) * Tests fixed to be compatible with Py26 again. (Issue #125) * Added ability to choose SSL version by passing an ``ssl.PROTOCOL_*`` constant to the ``ssl_version`` parameter of ``HTTPSConnectionPool``. (Issue #109) * Allow an explicit content type to be specified when encoding file fields. (Issue #126) * Exceptions are now pickleable, with tests. (Issue #101) * Fixed default headers not getting passed in some cases. (Issue #99) * Treat "content-encoding" header value as case-insensitive, per RFC 2616 Section 3.5. (Issue #110) * "Connection Refused" SocketErrors will get retried rather than raised. (Issue #92) * Updated vendored ``six``, no longer overrides the global ``six`` module namespace. (Issue #113) * ``urllib3.exceptions.MaxRetryError`` contains a ``reason`` property holding the exception that prompted the final retry. If ``reason is None`` then it was due to a redirect. (Issue #92, #114) * Fixed ``PoolManager.urlopen()`` from not redirecting more than once. (Issue #149) * Don't assume ``Content-Type: text/plain`` for multi-part encoding parameters that are not files. (Issue #111) * Pass `strict` param down to ``httplib.HTTPConnection``. (Issue #122) * Added mechanism to verify SSL certificates by fingerprint (md5, sha1) or against an arbitrary hostname (when connecting by IP or for misconfigured servers). (Issue #140) * Streaming decompression support. (Issue #159) 1.5 (2012-08-02) ---------------- * Added ``urllib3.add_stderr_logger()`` for quickly enabling STDERR debug logging in urllib3. * Native full URL parsing (including auth, path, query, fragment) available in ``urllib3.util.parse_url(url)``. * Built-in redirect will switch method to 'GET' if status code is 303. (Issue #11) * ``urllib3.PoolManager`` strips the scheme and host before sending the request uri. (Issue #8) * New ``urllib3.exceptions.DecodeError`` exception for when automatic decoding, based on the Content-Type header, fails. * Fixed bug with pool depletion and leaking connections (Issue #76). Added explicit connection closing on pool eviction. Added ``urllib3.PoolManager.clear()``. * 99% -> 100% unit test coverage. 1.4 (2012-06-16) ---------------- * Minor AppEngine-related fixes. * Switched from ``mimetools.choose_boundary`` to ``uuid.uuid4()``. * Improved url parsing. (Issue #73) * IPv6 url support. (Issue #72) 1.3 (2012-03-25) ---------------- * Removed pre-1.0 deprecated API. * Refactored helpers into a ``urllib3.util`` submodule. * Fixed multipart encoding to support list-of-tuples for keys with multiple values. (Issue #48) * Fixed multiple Set-Cookie headers in response not getting merged properly in Python 3. (Issue #53) * AppEngine support with Py27. (Issue #61) * Minor ``encode_multipart_formdata`` fixes related to Python 3 strings vs bytes. 1.2.2 (2012-02-06) ------------------ * Fixed packaging bug of not shipping ``test-requirements.txt``. (Issue #47) 1.2.1 (2012-02-05) ------------------ * Fixed another bug related to when ``ssl`` module is not available. (Issue #41) * Location parsing errors now raise ``urllib3.exceptions.LocationParseError`` which inherits from ``ValueError``. 1.2 (2012-01-29) ---------------- * Added Python 3 support (tested on 3.2.2) * Dropped Python 2.5 support (tested on 2.6.7, 2.7.2) * Use ``select.poll`` instead of ``select.select`` for platforms that support it. * Use ``Queue.LifoQueue`` instead of ``Queue.Queue`` for more aggressive connection reusing. Configurable by overriding ``ConnectionPool.QueueCls``. * Fixed ``ImportError`` during install when ``ssl`` module is not available. (Issue #41) * Fixed ``PoolManager`` redirects between schemes (such as HTTP -> HTTPS) not completing properly. (Issue #28, uncovered by Issue #10 in v1.1) * Ported ``dummyserver`` to use ``tornado`` instead of ``webob`` + ``eventlet``. Removed extraneous unsupported dummyserver testing backends. Added socket-level tests. * More tests. Achievement Unlocked: 99% Coverage. 1.1 (2012-01-07) ---------------- * Refactored ``dummyserver`` to its own root namespace module (used for testing). * Added hostname verification for ``VerifiedHTTPSConnection`` by vendoring in Py32's ``ssl_match_hostname``. (Issue #25) * Fixed cross-host HTTP redirects when using ``PoolManager``. (Issue #10) * Fixed ``decode_content`` being ignored when set through ``urlopen``. (Issue #27) * Fixed timeout-related bugs. (Issues #17, #23) 1.0.2 (2011-11-04) ------------------ * Fixed typo in ``VerifiedHTTPSConnection`` which would only present as a bug if you're using the object manually. (Thanks pyos) * Made RecentlyUsedContainer (and consequently PoolManager) more thread-safe by wrapping the access log in a mutex. (Thanks @christer) * Made RecentlyUsedContainer more dict-like (corrected ``__delitem__`` and ``__getitem__`` behaviour), with tests. Shouldn't affect core urllib3 code. 1.0.1 (2011-10-10) ------------------ * Fixed a bug where the same connection would get returned into the pool twice, causing extraneous "HttpConnectionPool is full" log warnings. 1.0 (2011-10-08) ---------------- * Added ``PoolManager`` with LRU expiration of connections (tested and documented). * Added ``ProxyManager`` (needs tests, docs, and confirmation that it works with HTTPS proxies). * Added optional partial-read support for responses when ``preload_content=False``. You can now make requests and just read the headers without loading the content. * Made response decoding optional (default on, same as before). * Added optional explicit boundary string for ``encode_multipart_formdata``. * Convenience request methods are now inherited from ``RequestMethods``. Old helpers like ``get_url`` and ``post_url`` should be abandoned in favour of the new ``request(method, url, ...)``. * Refactored code to be even more decoupled, reusable, and extendable. * License header added to ``.py`` files. * Embiggened the documentation: Lots of Sphinx-friendly docstrings in the code and docs in ``docs/`` and on https://urllib3.readthedocs.io/. * Embettered all the things! * Started writing this file. 0.4.1 (2011-07-17) ------------------ * Minor bug fixes, code cleanup. 0.4 (2011-03-01) ---------------- * Better unicode support. * Added ``VerifiedHTTPSConnection``. * Added ``NTLMConnectionPool`` in contrib. * Minor improvements. 0.3.1 (2010-07-13) ------------------ * Added ``assert_host_name`` optional parameter. Now compatible with proxies. 0.3 (2009-12-10) ---------------- * Added HTTPS support. * Minor bug fixes. * Refactored, broken backwards compatibility with 0.2. * API to be treated as stable from this version forward. 0.2 (2008-11-17) ---------------- * Added unit tests. * Bug fixes. 0.1 (2008-11-16) ---------------- * First release.

Home-page: https://github.com/Alir3z4/html2text/ Author: Aaron Swartz Author-email: me@aaronsw.com Maintainer: Alireza Savand Maintainer-email: alireza.savand@gmail.com License: GNU GPL 3 Description: # html2text [](https://travis-ci.org/Alir3z4/html2text) [](https://coveralls.io/r/Alir3z4/html2text) [](https://pypi.org/project/html2text/) [](https://pypi.org/project/html2text/) [](https://pypi.org/project/html2text/) [](https://pypi.org/project/html2text/) [](https://pypi.org/project/html2text/) html2text is a Python script that converts a page of HTML into clean, easy-to-read plain ASCII text. Better yet, that ASCII also happens to be valid Markdown (a text-to-HTML format). Usage: `html2text [filename [encoding]]` | Option | Description |--------------------------------------------------------|--------------------------------------------------- | `--version` | Show program's version number and exit | `-h`, `--help` | Show this help message and exit | `--ignore-links` | Don't include any formatting for links |`--escape-all` | Escape all special characters. Output is less readable, but avoids corner case formatting issues. | `--reference-links` | Use reference links instead of links to create markdown | `--mark-code` | Mark preformatted and code blocks with [code]...[/code] For a complete list of options see the [docs](https://github.com/Alir3z4/html2text/blob/master/docs/usage.md) Or you can use it from within `Python`: ``` >>> import html2text >>> >>> print(html2text.html2text("<p><strong>Zed's</strong> dead baby, <em>Zed's</em> dead.</p>")) **Zed's** dead baby, _Zed's_ dead. ``` Or with some configuration options: ``` >>> import html2text >>> >>> h = html2text.HTML2Text() >>> # Ignore converting links from HTML >>> h.ignore_links = True >>> print h.handle("<p>Hello, <a href='https://www.google.com/earth/'>world</a>!") Hello, world! >>> print(h.handle("<p>Hello, <a href='https://www.google.com/earth/'>world</a>!")) Hello, world! >>> # Don't Ignore links anymore, I like links >>> h.ignore_links = False >>> print(h.handle("<p>Hello, <a href='https://www.google.com/earth/'>world</a>!")) Hello, [world](https://www.google.com/earth/)! ``` *Originally written by Aaron Swartz.

Logical Hebrew ?? # # Both "ISO" charsets use a completely identical set of code points, whereas # "windows-1255" and "x-mac-hebrew" are two different proper supersets of # these code points. windows-1255 defines additional characters in the range # 0x80-0x9F as some misc punctuation marks as well as some Hebrew-specific # diacritics and additional 'Yiddish' ligature letters in the range 0xc0-0xd6. # x-mac-hebrew defines similar additional code points but with a different # mapping. # # As far as an average Hebrew text with no diacritics is concerned, all four # charsets are identical with respect to code points. Meaning that for the # main Hebrew alphabet, all four map the same values to all 27 Hebrew letters # (including final letters). # # The dominant difference between these charsets is their directionality. # "Visual" directionality means that the text is ordered as if the renderer is # not aware of a BIDI rendering algorithm. The renderer sees the text and # draws it from left to right. The text itself when ordered naturally is read # backwards. A buffer of Visual Hebrew generally looks like so: # "[last word of first line spelled backwards] [whole line ordered backwards # and spelled backwards] [first word of first line spelled backwards] # [end of line] [last word of second line] ... etc' " # adding punctuation marks, numbers and English text to visual text is # naturally also "visual" and from left to right. # # "Logical" directionality means the text is ordered "naturally" according to # the order it is read. It is the responsibility of the renderer to display # the text from right to left. A BIDI algorithm is used to place general # punctuation marks, numbers and English text in the text. # # Texts in x-mac-hebrew are almost impossible to find on the Internet. From # what little evidence I could find, it seems that its general directionality # is Logical. # # To sum up all of the above, the Hebrew probing mechanism knows about two # charsets: # Visual Hebrew - "ISO-8859-8" - backwards text - Words and sentences are # backwards while line order is natural. For charset recognition purposes # the line order is unimportant (In fact, for this implementation, even # word order is unimportant). # Logical Hebrew - "windows-1255" - normal, naturally ordered text. # # "ISO-8859-8-I" is a subset of windows-1255 and doesn't need to be # specifically identified. # "x-mac-hebrew" is also identified as windows-1255. A text in x-mac-hebrew # that contain special punctuation marks or diacritics is displayed with # some unconverted characters showing as question marks. This problem might # be corrected using another model prober for x-mac-hebrew. Due to the fact # that x-mac-hebrew texts are so rare, writing another model prober isn't # worth the effort and performance hit. # #### The Prober #### # # The prober is divided between two SBCharSetProbers and a HebrewProber, # all of which are managed, created, fed data, inquired and deleted by the # SBCSGroupProber. The two SBCharSetProbers identify that the text is in # fact some kind of Hebrew, Logical or Visual. The final decision about which # one is it is made by the HebrewProber by combining final-letter scores # with the scores of the two SBCharSetProbers to produce a final answer. # # The SBCSGroupProber is responsible for stripping the original text of HTML # tags, English characters, numbers, low-ASCII punctuation characters, spaces # and new lines. It reduces any sequence of such characters to a single space. # The buffer fed to each prober in the SBCS group prober is pure text in # high-ASCII. # The two SBCharSetProbers (model probers) share the same language model: # Win1255Model. # The first SBCharSetProber uses the model normally as any other # SBCharSetProber does, to recognize windows-1255, upon which this model was # built. The second SBCharSetProber is told to make the pair-of-letter # lookup in the language model backwards. This in practice exactly simulates # a visual Hebrew model using the windows-1255 logical Hebrew model. # # The HebrewProber is not using any language model. All it does is look for # final-letter evidence suggesting the text is either logical Hebrew or visual # Hebrew. Disjointed from the model probers, the results of the HebrewProber # alone are meaningless. HebrewProber always returns 0.00 as confidence # since it never identifies a charset by itself. Instead, the pointer to the # HebrewProber is passed to the model probers as a helper "Name Prober". # When the Group prober receives a positive identification from any prober, # it asks for the name of the charset identified. If the prober queried is a # Hebrew model prober, the model prober forwards the call to the # HebrewProber to make the final decision. In the HebrewProber, the # decision is made according to the final-letters scores maintained and Both # model probers scores.

This function works to filter all words that contain at least one international character. All contiguous sequences of markers are replaced by a single space ascii character.

For each byte the detector receives, it will feed that byte to every active state machine available, one byte at a time. The state machine changes its state based on its previous state and the byte it receives. There are 3 states in a state machine that are of interest to an auto-detector: START state: This is the state to start with, or a legal byte sequence (i.e. a valid code point) for character has been identified. ME state: This indicates that the state machine identified a byte sequence that is specific to the charset it is designed for and that there is no other possible encoding which can contain this byte sequence. This will to lead to an immediate positive answer for the detector. ERROR state: This indicates the state machine identified an illegal byte sequence for that encoding. This will lead to an immediate negative answer for this encoding. Detector will exclude this encoding from consideration from here on. c C s0 || _ d| _d| _d | _tjt�| _| j� d S )Nr ) �_model�_curr_byte_pos�_curr_char_len� _curr_state�loggingZ

to contain a series of words delimited by markers. This function works to filter all words that contain at least one international character. All contiguous sequences of markers are replaced by a single space ascii character.

ZdZdd� Zdd� Zdd� Zdd � Zd d � Ze d d � �Z dS )�CodingStateMachinea� A state machine to verify a byte sequence for a particular encoding. For each byte the detector receives, it will feed that byte to every active state machine available, one byte at a time. The state machine changes its state based on its previous state and the byte it receives. There are 3 states in a state machine that are of interest to an auto-detector: START state: This is the state to start with, or a legal byte sequence (i.e. a valid code point) for character has been identified. ME state: This indicates that the state machine identified a byte sequence that is specific to the charset it is designed for and that there is no other possible encoding which can contain this byte sequence. This will to lead to an immediate positive answer for the detector. ERROR state: This indicates the state machine identified an illegal byte sequence for that encoding. This will lead to an immediate negative answer for this encoding. Detector will exclude this encoding from consideration from here on. c C s0 || _ d| _d| _d | _tjt�| _| j� d S )Nr ) �_model�_curr_byte_pos�_curr_char_len� _curr_state�loggingZ

The grammer is specified by supplying the BNF inside # Python documentation strings. The inspiration for this technique was borrowed # from John Aycock's Spark parsing system. PLY might be viewed as cross between # Spark and the GNU bison utility. # # The current implementation is only somewhat object-oriented. The # LR parser itself is defined in terms of an object (which allows multiple # parsers to co-exist). However, most of the variables used during table # construction are defined in terms of global variables. Users shouldn't # notice unless they are trying to define multiple parsers at the same # time using threads (in which case they should have their head examined). # # This implementation supports both SLR and LALR(1) parsing. LALR(1) # support was originally implemented by Elias Ioup (ezioup@alumni.uchicago.edu), # using the algorithm found in Aho, Sethi, and Ullman "Compilers: Principles, # Techniques, and Tools" (The Dragon Book). LALR(1) has since been replaced # by the more efficient DeRemer and Pennello algorithm. # # :::::::: WARNING ::::::: # # Construction of LR parsing tables is fairly complicated and expensive. # To make this module run fast, a *LOT* of work has been put into # optimization---often at the expensive of readability and what might # consider to be good Python "coding style."

For clients, that callback is expected to check the OCSP data, and returns a negative value on error, 0 if the response is not acceptable, or positive if it is. These are mutually exclusive return code behaviours, and they mean that we need two helpers so that we always return an appropriate error code if the user's code throws an exception. Given that we have to have two helpers anyway, these helpers are a bit more helpery than most: specifically, they hide a few more of the OpenSSL functions so that the user has an easier time writing these callbacks.

This helper implements the client side. c s2 t j�� t� �� �fdd��}tjd|��_d S )Nc s� yxt j| }|tjkr"tj|�}nd }tjd�}tj| |�}|dk rJd}ntj|d |�d d � }� |||�}t t |��S t k r� } z�j j |� dS d }~X nX d S )Nzunsigned char **r r� ru ���)rn r� r� r� r� r� r� Z SSL_get_tlsext_status_ocsp_respr� �int�boolr� r� r� ) r� r� r� r� Zocsp_ptrZocsp_lenr� Zvalidr� )r� r� rs rt r� 9 s z3_OCSPClientCallbackHelper.__init__.<locals>.wrapperzint (*)(SSL *, void *))r� r� r r� r� )r� r� r� rs )r� r� rt r� 6 s z"_OCSPClientCallbackHelper.__init__N)rp rq rr r r� rs rs rs rt r� s r� c C sd d }t | t�s(t| dd �}|d k r(|� } t | t�r6| }t |t�sJtd��n|dk r`td|f ��|S )N�filenoz3argument must be an int, or have a fileno() method.r z1file descriptor cannot be a negative integer (%i))r� r �getattrr� � ValueError)�obj�fd�methrs rs rt �_asFileDescriptor[ s r� c C s t jtj| ��S )z� Return a string describing the version of OpenSSL in use. :param type: One of the :const:`SSLEAY_` constants defined in this module. )r� �stringr� rk )�typers rs rt rk n s c s � �fdd�}|S )a� Builds a decorator that ensures that functions that rely on OpenSSL functions that are not present in this build raise NotImplementedError, rather than AttributeError coming out of cryptography. :param flag: A cryptography flag that guards the functions, e.g. ``Cryptography_HAS_NEXTPROTONEG``. :param error: The string to be used in the exception if the flag is false. c s$ �s t | �� fdd��}|S | S d S )Nc s t � ��d S )N)�NotImplementedError)�args�kwargs)�errorrs rt �explode� s z<_make_requires.<locals>._requires_decorator.<locals>.explode)r )�funcr� )r� �flagrs rt �_requires_decorator� s z+_make_requires.<locals>._requires_decoratorrs )r� r� r� rs )r� r� rt �_make_requiresw s r� zNPN not availablezALPN not availablezSNI not availablec @ s e Zd ZdZdS )rl z� A class representing an SSL session.

For clients, that callback is expected to check the OCSP data, and returns a negative value on error, 0 if the response is not acceptable, or positive if it is. These are mutually exclusive return code behaviours, and they mean that we need two helpers so that we always return an appropriate error code if the user's code throws an exception. Given that we have to have two helpers anyway, these helpers are a bit more helpery than most: specifically, they hide a few more of the OpenSSL functions so that the user has an easier time writing these callbacks.

The package resource API expects resource names to have their path parts separated with ``/``, *not* whatever the local path separator is. Do not use os.path operations to manipulate resource names being passed into the API. The package resource API is designed to work with normal filesystem packages, .egg files, and unpacked .egg files. It can also work in a limited way with .zip files and with custom PEP 302 loaders that support the ``get_data()`` method. � )�absolute_importN)� get_importer)�six)�urllib�map�filter)�utime)�mkdir�rename�unlinkTF)�open)�isdir�split� )� py31compat)�appdirs)� packagingz&pkg_resources.extern.packaging.versionz)pkg_resources.extern.packaging.specifiersz+pkg_resources.extern.packaging.requirementsz&pkg_resources.extern.packaging.markers� z Python 3.3 or later is requiredc @ s e Zd ZdZdS )� PEP440Warningza Used when there is an issue with a version or specifier not complying with PEP 440.

To allow usage of packages that explicitly require a newer version of Mac OS X, we must also know the current version of the OS.

If not supplied, it defaults to all distributions available within any entry or distribution in the working set. `installer`, if supplied, will be invoked with each requirement that cannot be met by an already-installed distribution; it should return a ``Distribution`` or ``None``. Unless `replace_conflicting=True`, raises a VersionConflict exception if any requirements are found on the path that have the correct name but the wrong version. Otherwise, if an `installer` is supplied it will be invoked to obtain the correct version of the requirement and activate it. `extras` is a list of the extras to be used with these requirements. This is important because extra requirements may look like `my_req; extra = "my_extra"`, which would otherwise be interpreted as a purely optional requirement. Instead, we want to be able to assert that these requirements are truly required.

The `full_env`, if supplied, should be an ``Environment`` contains all currently-available distributions. If `full_env` is not supplied, one is created automatically from the ``WorkingSet`` this method is called on, which will typically mean that every directory on ``sys.path`` will be scanned for distributions. `installer` is a standard installer callback as used by the ``resolve()`` method. The `fallback` flag indicates whether we should attempt to resolve older versions of a plugin if the newest version cannot be resolved. This method returns a 2-tuple: (`distributions`, `error_info`), where `distributions` is a list of the distributions found in `plugin_env` that were loadable, along with any other distributions that are needed to resolve their dependencies. `error_info` is a dictionary mapping unloadable plugin distributions to an exception instance describing the error that occurred. Usually this will be a ``DistributionNotFound`` or ``VersionConflict`` instance.

If not supplied, ``sys.path`` is used. `platform` is an optional string specifying the name of the platform that platform-specific distributions must be compatible with. If unspecified, it defaults to the current platform. `python` is an optional string naming the desired version of Python (e.g. ``'3.3'``); it defaults to the current version. You may explicitly set `platform` (and/or `python`) to ``None`` if you wish to map *all* distributions, not just those compatible with the running platform or Python version.

(Which is based on the ``PYTHON_EGG_CACHE`` environment variable, with various platform-specific fallbacks. See that routine's documentation for more details.) Resources are extracted to subdirectories of this path based upon information given by the ``IResourceProvider``. You may set this to a temporary directory, but then you must call ``cleanup_resources()`` to delete the extracted files when done. There is no guarantee that ``cleanup_resources()`` will be able to remove all extracted files.

The package resource API expects resource names to have their path parts separated with ``/``, *not* whatever the local path separator is. Do not use os.path operations to manipulate resource names being passed into the API. The package resource API is designed to work with normal filesystem packages, .egg files, and unpacked .egg files. It can also work in a limited way with .zip files and with custom PEP 302 loaders that support the ``get_data()`` method. � )�absolute_importN)� get_importer)�six)�urllib�map�filter)�utime)�mkdir�rename�unlinkTF)�open)�isdir�split� )� py31compat)�appdirs)� packagingz&pkg_resources.extern.packaging.versionz)pkg_resources.extern.packaging.specifiersz+pkg_resources.extern.packaging.requirementsz&pkg_resources.extern.packaging.markers� z Python 3.3 or later is requiredc @ s e Zd ZdZdS )� PEP440Warningza Used when there is an issue with a version or specifier not complying with PEP 440.

To allow usage of packages that explicitly require a newer version of Mac OS X, we must also know the current version of the OS. If this condition occurs for any other platform with a version in its platform strings, this function should be extended accordingly.

Unless `replace_conflicting=True`, raises a VersionConflict exception if any requirements are found on the path that have the correct name but the wrong version. Otherwise, if an `installer` is supplied it will be invoked to obtain the correct version of the requirement and activate it. `extras` is a list of the extras to be used with these requirements. This is important because extra requirements may look like `my_req; extra = "my_extra"`, which would otherwise be interpreted as a purely optional requirement.

If `full_env` is not supplied, one is created automatically from the ``WorkingSet`` this method is called on, which will typically mean that every directory on ``sys.path`` will be scanned for distributions. `installer` is a standard installer callback as used by the ``resolve()`` method. The `fallback` flag indicates whether we should attempt to resolve older versions of a plugin if the newest version cannot be resolved. This method returns a 2-tuple: (`distributions`, `error_info`), where `distributions` is a list of the distributions found in `plugin_env` that were loadable, along with any other distributions that are needed to resolve their dependencies. `error_info` is a dictionary mapping unloadable plugin distributions to an exception instance describing the error that occurred. Usually this will be a ``DistributionNotFound`` or ``VersionConflict`` instance.

Snapshot distributions available on a search path Any distributions found on `search_path` are added to the environment. `search_path` should be a sequence of ``sys.path`` items. If not supplied, ``sys.path`` is used. `platform` is an optional string specifying the name of the platform that platform-specific distributions must be compatible with. If unspecified, it defaults to the current platform. `python` is an optional string naming the desired version of Python (e.g. ``'3.3'``); it defaults to the current version. You may explicitly set `platform` (and/or `python`) to ``None`` if you wish to map *all* distributions, not just those compatible with the running platform or Python version.

If a suitable distribution isn't active, this method returns the newest distribution in the environment that meets the ``Requirement`` in `req`.

(Which is based on the ``PYTHON_EGG_CACHE`` environment variable, with various platform-specific fallbacks. See that routine's documentation for more details.) Resources are extracted to subdirectories of this path based upon information given by the ``IResourceProvider``. You may set this to a temporary directory, but then you must call ``cleanup_resources()`` to delete the extracted files when done. There is no guarantee that ``cleanup_resources()`` will be able to remove all extracted files.

With pyparsing, you don't need to learn a new syntax for defining grammars or matching expressions - the parsing module provides a library of classes that you use to construct the grammar directly in Python. Here is a program to parse "Hello, World!" (or any greeting of the form C{"<salutation>, <addressee>!"}), built up using L{Word}, L{Literal}, and L{And} elements (L{'+'<ParserElement.__add__>} operator gives L{And} expressions, strings are auto-converted to L{Literal} expressions):: from pyparsing import Word, alphas # define grammar of a greeting greet = Word(alphas) + "," + Word(alphas) + "!" hello = "Hello, World!" print (hello, "->", greet.parseString(hello)) The program outputs the following:: Hello, World! -> ['Hello', ',', 'World', '!'] The Python representation of the grammar is quite readable, owing to the self-explanatory class names, and the use of '+', '|' and '^' operators. The L{ParseResults} object returned from L{ParserElement.parseString<ParserElement.parseString>} can be accessed as a nested list, a dictionary, or an object with named attributes. The pyparsing module handles some of the problems that are typically vexing when writing text parsers: - extra or missing whitespace (the above program will also handle "Hello,World!", "Hello , World !", etc.) - quoted strings - embedded comments z2.1.10z07 Oct 2016 01:31 UTCz*Paul McGuire <ptmcg@users.sourceforge.net>� N)�ref)�datetime)�RLock)� OrderedDict�And�CaselessKeyword�CaselessLiteral� CharsNotIn�Combine�Dict�Each�Empty� FollowedBy�Forward� GoToColumn�Group�Keyword�LineEnd� LineStart�Literal� MatchFirst�NoMatch�NotAny� OneOrMore�OnlyOnce�Optional�Or�ParseBaseException�ParseElementEnhance�ParseException�ParseExpression�ParseFatalException� ParseResults�ParseSyntaxException� ParserElement� QuotedString�RecursiveGrammarException�Regex�SkipTo� StringEnd� StringStart�Suppress�Token�TokenConverter�White�Word�WordEnd� WordStart� ZeroOrMore� alphanums�alphas� alphas8bit� anyCloseTag� anyOpenTag� cStyleComment�col�commaSeparatedList�commonHTMLEntity� countedArray�cppStyleComment�dblQuotedString�dblSlashComment� delimitedList�dictOf�downcaseTokens�empty�hexnums� htmlComment�javaStyleComment�line�lineEnd� lineStart�lineno� makeHTMLTags� makeXMLTags�matchOnlyAtCol�matchPreviousExpr�matchPreviousLiteral� nestedExpr�nullDebugAction�nums�oneOf�opAssoc�operatorPrecedence� printables�punc8bit�pythonStyleComment� quotedString� removeQuotes�replaceHTMLEntity� replaceWith� restOfLine�sglQuotedString�srange� stringEnd� stringStart�traceParseAction� unicodeString� upcaseTokens� withAttribute� indentedBlock�originalTextFor�ungroup� infixNotation� locatedExpr� withClass� CloseMatch�tokenMap�pyparsing_common� c C s` t | t�r| S yt| �S tk rZ t| �jtj� d�}td�}|jdd� � |j |�S X dS )a Drop-in replacement for str(obj) that tries to be Unicode friendly.

Parse action fn is a callable method with 0-3 arguments, called as C{fn(s,loc,toks)}, C{fn(loc,toks)}, C{fn(toks)}, or just C{fn()}, where: - s = the original string being parsed (see note below) - loc = the location of the matching substring - toks = a list of the matched tokens, packaged as a C{L{ParseResults}} object If the functions in fns modify the tokens, they can return them as the return value from fn, and the modified list of tokens will replace the original. Otherwise, fn does not need to return any value. Optional keyword arguments: - callDuringTry = (default=C{False}) indicate if parse action should be run during lookaheads and alternate testing Note: the default parsing behavior is to expand tabs in the input string before starting the parsing process.

Repeated parse attempts at the same string location (which happens often in many complex grammars) can immediately return a cached value, instead of re-executing parsing/validating code. Memoizing is done of both valid results and parsing exceptions. Parameters: - cache_size_limit - (default=C{128}) - if an integer value is provided will limit the size of the packrat cache; if None is passed, then the cache size will be unbounded; if 0 is passed, the cache will be effectively disabled. This speedup may break existing programs that use parse actions that have side-effects. For this reason, packrat parsing is disabled when you first import pyparsing. To activate the packrat feature, your program must call the class method C{ParserElement.enablePackrat()}. If your program uses C{psyco} to "compile as you go", you must call C{enablePackrat} before calling C{psyco.full()}. If you do not do this, Python will crash. For best results, call C{enablePackrat()} immediately after importing pyparsing. Example:: import pyparsing pyparsing.ParserElement.enablePackrat() TN)r$ �_packratEnabledr� r� r� r� rt )Zcache_size_limitrw rw rx � enablePackrat s zParserElement.enablePackratc C s� t j� | js| j� x| jD ] }|j� q W | js<|j� }y<| j|d�\}}|rv| j||�}t � t � }|j||� W n0 t k r� } zt j r�� n|�W Y dd}~X nX |S dS )aB Execute the parse expression with the given string. This is the main interface to the client code, once the complete expression has been built. If you want the grammar to require that the entire input string be successfully parsed, then set C{parseAll} to True (equivalent to ending the grammar with C{L{StringEnd()}}). Note: C{parseString} implicitly calls C{expandtabs()} on the input string, in order to report proper column numbers in parse actions. If the input string contains tabs and the grammar uses parse actions that use the C{loc} argument to index into the string being parsed, you can ensure you have a consistent view of the input string by: - calling C{parseWithTabs} on your grammar before calling C{parseString} (see L{I{parseWithTabs}<parseWithTabs>}) - define your parse action using the full C{(s,loc,toks)} signature, and reference the input string using the parse action's C{s} argument - explictly expand the tabs in your input string before calling C{parseString} Example:: Word('a').parseString('aaaaabaaa') # -> ['aaaaa'] Word('a').parseString('aaaaabaaa', parseAll=True) # -> Exception: Expected end of text r N) r$ r� r_ � streamliner] r\ � expandtabsrt r� r r) r �verbose_stacktrace)r� r- �parseAllr� r� r� Zser3 rw rw rx � parseString# s$ zParserElement.parseStringc c s@ | j s| j� x| jD ] }|j� qW | js8t|�j� }t|�}d}| j}| j}t j � d} y�x�||kon| |k �ry |||�} ||| dd�\} } W n t k r� | d }Y q`X | |kr�| d7 } | | | fV |r�|||�} | |kr�| }q�|d7 }n| }q`| d }q`W W n4 t k �r: } zt j �r&� n|�W Y dd}~X nX dS )a� Scan the input string for expression matches. Each match will return the matching tokens, start location, and end location. May be called with optional C{maxMatches} argument, to clip scanning after 'n' matches are found. If C{overlap} is specified, then overlapping matches will be reported. Note that the start and end locations are reported relative to the string being parsed. See L{I{parseString}<parseString>} for more information on parsing strings with embedded tabs. Example:: source = "sldjf123lsdjjkf345sldkjf879lkjsfd987" print(source) for tokens,start,end in Word(alphas).scanString(source): print(' '*start + '^'*(end-start)) print(' '*start + tokens[0]) prints:: sldjf123lsdjjkf345sldkjf879lkjsfd987 ^^^^^ sldjf ^^^^^^^ lsdjjkf ^^^^^^ sldkjf ^^^^^^ lkjsfd r F)rp rr N)r_ r� r] r\ r� r� r� r� rt r$ r� r r r� )r� r- � maxMatchesZoverlapr� r� r� Z preparseFnZparseFn�matchesr� ZnextLocr� Znextlocr3 rw rw rx � scanStringU sB zParserElement.scanStringc C s� g }d}d| _ y�xh| j|�D ]Z\}}}|j|||� � |rrt|t�rT||j� 7 }n t|t�rh||7 }n |j|� |}q W |j||d� � dd� |D �}djtt t |���S t k r� } zt j rȂ n|�W Y dd}~X nX dS )af Extension to C{L{scanString}}, to modify matching text with modified tokens that may be returned from a parse action. To use C{transformString}, define a grammar and attach a parse action to it that modifies the returned token list. Invoking C{transformString()} on a target string will then scan for matches, and replace the matched text patterns according to the logic in the parse action. C{transformString()} returns the resulting transformed string. Example:: wd = Word(alphas) wd.setParseAction(lambda toks: toks[0].title()) print(wd.transformString("now is the winter of our discontent made glorious summer by this sun of york."))

C{CloseMatch} takes parameters: - C{match_string} - string to be matched - C{maxMismatches} - (C{default=1}) maximum number of mismatches allowed to count as a match The results from a successful parse will contain the matched text from the input string and the following named results: - C{mismatches} - a list of the positions within the match_string where mismatches were found - C{original} - the original match_string used to compare against the input string If C{mismatches} is an empty list, then the match was an exact match. Example:: patt = CloseMatch("ATCATCGAATGGA") patt.parseString("ATCATCGAAXGGA") # -> (['ATCATCGAAXGGA'], {'mismatches': [[9]], 'original': ['ATCATCGAATGGA']}) patt.parseString("ATCAXCGAAXGGA") # -> Exception: Expected 'ATCATCGAATGGA' (with up to 1 mismatches) (at char 0), (line:1, col:1) # exact match patt.parseString("ATCATCGAATGGA") # -> (['ATCATCGAATGGA'], {'mismatches': [[]], 'original': ['ATCATCGAATGGA']}) # close match allowing up to 2 mismatches patt = CloseMatch("ATCATCGAATGGA", maxMismatches=2) patt.parseString("ATCAXCGAAXGGA") # -> (['ATCAXCGAAXGGA'], {'mismatches': [[4, 9]], 'original': ['ATCATCGAATGGA']}) rr c sB t t| �j� || _|| _|| _d| j| jf | _d| _d| _d S )Nz&Expected %r (with up to %d mismatches)F) r� rl r� r� � match_string� maxMismatchesra r` r[ )r� r� r� )rH rw rx r� � s zCloseMatch.__init__Tc C s� |}t |�}|t | j� }||kr�| j}d}g } | j} x�tt|||� | j��D ]0\}} | \} } | | krP| j|� t | �| krPP qPW |d }t|||� g�}| j|d< | |d< ||fS t||| j| ��d S )Nr rr �original� mismatches) r� r� r� r� r� r� r" r ra )r� r- r� ro �startr� �maxlocr� Zmatch_stringlocr� r� Zs_m�src�mat�resultsrw rw rx r� � s( " zCloseMatch.parseImpl)rr )T)r� r� r� r� r� r� r� rw rw )rH rx rl � s c s8 e Zd ZdZd � fdd� Zdd d �Z� fd d �Z� ZS )r/ a Token for matching words composed of allowed character sets. Defined with string containing all allowed initial characters, an optional string containing allowed body characters (if omitted, defaults to the initial character set), and an optional minimum, maximum, and/or exact length. The default value for C{min} is 1 (a minimum value < 1 is not valid); the default values for C{max} and C{exact} are 0, meaning no maximum or exact length restriction. An optional C{excludeChars} parameter can list characters that might be found in the input C{bodyChars} string; useful to define a word of all printables except for one or two characters, for instance. L{srange} is useful for defining custom character set strings for defining C{Word} expressions, using range notation from regular expression character sets. A common mistake is to use C{Word} to match a specific literal string, as in C{Word("Address")}. Remember that C{Word} uses the string argument to define I{sets} of matchable characters. This expression would match "Add", "AAA", "dAred", or any other word made up of the characters 'A', 'd', 'r', 'e', and 's'. To match an exact literal string, use L{Literal} or L{Keyword}. pyparsing includes helper strings for building Words: - L{alphas} - L{nums} - L{alphanums} - L{hexnums} - L{alphas8bit} (alphabetic characters in ASCII range 128-255 - accented, tilded, umlauted, etc.) - L{punc8bit} (non-alphabetic characters in ASCII range 128-255 - currency, symbols, superscripts, diacriticals, etc.) - L{printables} (any non-whitespace character) Example:: # a word composed of digits integer = Word(nums) # equivalent to Word("0123456789") or Word(srange("0-9")) # a word with a leading capital, and zero or more lowercase capital_word = Word(alphas.upper(), alphas.lower()) # hostnames are alphanumeric, with leading alpha, and '-' hostname = Word(alphas, alphanums+'-') # roman numeral (not a strict parser, accepts invalid mix of characters) roman = Word("IVXLCDM") # any string of non-whitespace characters, except for ',' csv_value = Word(printables, excludeChars=",") Nrr r Fc s� t t| �j� � rFdj� fdd�|D ��}|rFdj� fdd�|D ��}|| _t|�| _|rl|| _t|�| _n|| _t|�| _|dk| _ |dk r�t d��|| _ |dkr�|| _ nt | _ |dkr�|| _ || _ t| �| _d| j | _d | _|| _d | j| j k�r�|dk�r�|dk�r�|dk�r�| j| jk�r8d t| j� | _nHt| j�dk�rfd tj| j�t| j�f | _nd t| j�t| j�f | _| j�r�d| j d | _ytj| j�| _W n tk �r� d | _Y nX d S )Nr� c 3 s | ]}|� kr|V qd S )Nrw )r� r� )� excludeCharsrw rx r� 7 s z Word.__init__.<locals>.<genexpr>c 3 s | ]}|� kr|V qd S )Nrw )r� r� )r� rw rx r� 9 s r rr zZcannot specify a minimum length < 1; use Optional(Word()) if zero-length word is permittedz Expected Fr� z[%s]+z%s[%s]*z [%s][%s]*z\b)r� r/ r� r� � initCharsOrigr� � initChars� bodyCharsOrig� bodyChars� maxSpecifiedr� �minLen�maxLenr� r� r� ra r` � asKeyword�_escapeRegexRangeChars�reStringr� rd �escape�compilerK )r� r r �min�max�exactr r� )rH )r� rx r� 4 sT 0 z Word.__init__Tc C sD | j r<| j j||�}|s(t||| j| ��|j� }||j� fS || | jkrZt||| j| ��|}|d7 }t|�}| j}|| j }t ||�}x ||k r�|| |kr�|d7 }q�W d} || | j k r�d} | j r�||k r�|| |kr�d} | j �r |dk�r||d |k�s||k �r || |k�r d} | �r4t||| j| ��||||� fS )Nrr FTr )rd r� r ra �end�groupr r� r r r r r r ) r� r- r� ro r� r� r� Z bodycharsr� ZthrowExceptionrw rw rx r� j s6 4zWord.parseImplc st yt t| �j� S tk r" Y nX | jd krndd� }| j| jkr^d|| j�|| j�f | _nd|| j� | _| jS )Nc S s$ t | �dkr | d d� d S | S d S )N� z...)r� )r� rw rw rx � charsAsStr� s z Word.__str__.<locals>.charsAsStrz W:(%s,%s)zW:(%s))r� r/ r� rK rU r� r )r� r )rH rw rx r� � s z Word.__str__)Nrr r r FN)T)r� r� r� r� r� r� r� r� rw rw )rH rx r/ s .6 #c sF e Zd ZdZeejd��Zd � fdd� Zd dd�Z � fd d �Z � Z S ) r' a� Token for matching strings that match a given regular expression.

When the expression is known, it is assigned to the C{Forward} variable using the '<<' operator. Note: take care when assigning to C{Forward} not to overlook precedence of operators. Specifically, '|' has a lower precedence than '<<', so that:: fwdExpr << a | b | c will actually be evaluated as:: (fwdExpr << a) | b | c thereby leaving b and c out as parseable alternatives. It is recommended that you explicitly group the values inserted into the C{Forward}:: fwdExpr << (a | b | c) Converting to use the '<<=' operator instead will avoid this problem.

By default, the list elements and delimiters can have intervening whitespace, and comments, but this can be overridden by passing C{combine=True} in the constructor. If C{combine} is set to C{True}, the matching tokens are returned as a single token string, with the delimiters included; otherwise, the matching tokens are returned as a list of tokens, with the delimiters suppressed. Example:: delimitedList(Word(alphas)).parseString("aa,bb,cc") # -> ['aa', 'bb', 'cc'] delimitedList(Word(hexnums), delim=':', combine=True).parseString("AA:BB:CC:DD:EE") # -> ['AA:BB:CC:DD:EE'] z [r� z]...N)r� r r2 ri r+ )r.

This helper defines a pattern of the form:: integer expr expr expr... where the leading integer tells how many expr expressions follow. The matched tokens returns the array of expr tokens as a list - the leading count token is suppressed. If C{intExpr} is specified, it should be a pyparsing expression that produces an integer value. Example:: countedArray(Word(alphas)).parseString('2 ab cd ef') # -> ['ab', 'cd'] # in this parser, the leading integer value is given in binary, # '10' indicating that 2 values are in the array binaryConstant = Word('01').setParseAction(lambda t: int(t[0], 2)) countedArray(Word(alphas), intExpr=binaryConstant).parseString('10 ab cd ef') # -> ['ab', 'cd'] c s. |d }� |r t t�g| ��p&t t�> g S )Nr )r r rC )r� r5 rv r� )� arrayExprr. rw rx �countFieldParseAction_ s "z+countedArray.<locals>.countFieldParseActionNc S s t | d �S )Nr )ru )rv rw rw rx ry d s z countedArray.<locals>.<lambda>ZarrayLenT)rf z(len) z...)r r/ rR r� r� ri rx r� )r.

Parameters: - strs - a string of space-delimited literals, or a collection of string literals - caseless - (default=C{False}) - treat all literals as caseless - useRegex - (default=C{True}) - as an optimization, will generate a Regex object; otherwise, will generate a C{MatchFirst} object (if C{caseless=True}, or if creating a C{Regex} raises an exception) Example:: comp_oper = oneOf("< = > <= >= !=") var = Word(alphas) number = Word(nums) term = var | number comparison_expr = term + comp_oper + term print(comparison_expr.searchString("B = 12 AA=23 B<=AA AA>12")) prints:: [['B', '=', '12'], ['AA', '=', '23'], ['B', '<=', 'AA'], ['AA', '>', '12']] c S s | j � |j � kS )N)r� )r �brw rw rx ry � s zoneOf.<locals>.<lambda>c S s |j � j| j � �S )N)r� r� )r rl rw rw rx ry � s c S s | |kS )Nrw )r rl rw rw rx ry � s c S s |j | �S )N)r� )r rl rw rw rx ry � s z6Invalid argument to oneOf, expected string or iterablerq )r� r rr Nr� z[%s]c s s | ]}t |�V qd S )N)r )r� �symrw rw rx r� � s zoneOf.<locals>.<genexpr>z | �|c s s | ]}t j|�V qd S )N)rd r )r� rm rw rw rx r� � s z7Exception creating Regex for oneOf, building MatchFirstc 3 s | ]}� |�V qd S )Nrw )r� rm )�parseElementClassrw rx r� � s )r r rz r� r� r� r5 r� r� r� r� r r� r� r� r� r' ri rK r ) Zstrsr� ZuseRegexZisequalZmasksZsymbolsr� Zcurr� r� rw )ro rx rS � sL ((c C s t tt| | ���S )a� Helper to easily and clearly define a dictionary by specifying the respective patterns for the key and value. Takes care of defining the C{L{Dict}}, C{L{ZeroOrMore}}, and C{L{Group}} tokens in the proper order. The key pattern can include delimiting markers or punctuation, as long as they are suppressed, thereby leaving the significant key text. The value pattern can include named results, so that the C{Dict} results can include named token fields. Example:: text = "shape: SQUARE posn: upper left color: light blue texture: burlap" attr_expr = (label + Suppress(':') + OneOrMore(data_word, stopOn=label).setParseAction(' '.join)) print(OneOrMore(attr_expr).parseString(text).dump()) attr_label = label attr_value = Suppress(':') + OneOrMore(data_word, stopOn=label).setParseAction(' '.join) # similar to Dict, but simpler call format result = dictOf(attr_label, attr_value).parseString(text) print(result.dump()) print(result['shape']) print(result.shape) # object attribute access works too print(result.asDict()) prints:: [['shape', 'SQUARE'], ['posn', 'upper left'], ['color', 'light blue'], ['texture', 'burlap']] - color: light blue - posn: upper left - shape: SQUARE - texture: burlap SQUARE SQUARE {'color': 'light blue', 'shape': 'SQUARE', 'posn': 'upper left', 'texture': 'burlap'} )r r2 r )r� r� rw rw rx rA � s !c C s^ t � jdd� �}|j� }d|_|d�| |d� }|r@dd� }ndd� }|j|� | j|_|S ) a� Helper to return the original, untokenized text for a given expression. Useful to restore the parsed fields of an HTML start tag into the raw tag text itself, or to revert separate tokens with intervening whitespace back to the original matching input text. By default, returns astring containing the original parsed text. If the optional C{asString} argument is passed as C{False}, then the return value is a C{L{ParseResults}} containing any results names that were originally matched, and a single token containing the original matched text from the input string. So if the expression passed to C{L{originalTextFor}} contains expressions with defined results names, you must set C{asString} to C{False} if you want to preserve those results name values. Example:: src = "this is test <b> bold <i>text</i> </b> normal text " for tag in ("b","i"): opener,closer = makeHTMLTags(tag) patt = originalTextFor(opener + SkipTo(closer) + closer) print(patt.searchString(src)[0]) prints:: ['<b> bold <i>text</i> </b>'] ['<i>text</i>'] c S s |S )Nrw )r� r� rv rw rw rx ry 8 s z!originalTextFor.<locals>.<lambda>F�_original_start� _original_endc S s | |j |j� S )N)rp rq )r� r5 rv rw rw rx ry = s c S s& | |j d�|j d�� g|d d �< d S )Nrp rq )r� )r� r5 rv rw rw rx � extractText? s z$originalTextFor.<locals>.extractText)r r� r� re r] )r.

Borrows syntax from regexp '[]' string range definitions:: srange("[0-9]") -> "0123456789" srange("[a-z]") -> "abcdefghijklmnopqrstuvwxyz" srange("[a-z$_]") -> "abcdefghijklmnopqrstuvwxyz$_" The input string must be enclosed in []'s, and the returned string is the expanded character set joined into a single string. The values enclosed in the []'s may be: - a single character - an escaped character with a leading backslash (such as C{\-} or C{\]}) - an escaped hex character with a leading C{'\x'} (C{\x21}, which is a C{'!'} character) (C{\0x##} is also supported for backwards compatibility) - an escaped octal character with a leading C{'\0'} (C{\041}, which is a C{'!'} character) - a range of any of the above, separated by a dash (C{'a-z'}, etc.) - any combination of the above (C{'aeiouy'}, C{'a-zA-Z0-9_$'}, etc.) c S s< t | t�s| S djdd� tt| d �t| d �d �D ��S )Nr� c s s | ]}t |�V qd S )N)ru )r� r� rw rw rx r� � s z+srange.<locals>.<lambda>.<locals>.<genexpr>r rr )rz r" r� r� �ord)�prw rw rx ry � s zsrange.<locals>.<lambda>r� c 3 s | ]}� |�V qd S )Nrw )r� �part)� _expandedrw rx r� � s zsrange.<locals>.<genexpr>N)r� �_reBracketExprr� rx rK )r� rw )r| rx r_ r s c s � fdd�}|S )zt Helper method for defining parse actions that require matching at a specific column in the input text. c s" t || �� kr t| |d� ��d S )Nz matched token not at column %d)r9 r )r) Zlocnr1 )r� rw rx � verifyCol� s z!matchOnlyAtCol.<locals>.verifyColrw )r� r~ rw )r� rx rM � s c s � fdd�S )a� Helper method for common parse actions that simply return a literal value.

Use C{withAttribute} to qualify a starting tag with a required attribute value, to avoid false matches on common tags such as C{<TD>} or C{<DIV>}. Call C{withAttribute} with a series of attribute names and values. Specify the list of filter attributes names and values as: - keyword arguments, as in C{(align="right")}, or - as an explicit dict with C{**} operator, when an attribute name is also a Python reserved word, as in C{**{"class":"Customer", "align":"right"}} - a list of name-value tuples, as in ( ("ns1:class", "Customer"), ("ns2:align","right") ) For attribute names with a namespace prefix, you must use the second form. Attribute names are matched insensitive to upper/lower case. If just testing for C{class} (with or without a namespace), use C{L{withClass}}. To verify that the attribute exists, but without specifying a value, pass C{withAttribute.ANY_VALUE} as the value. Example:: html = ''' <div> Some text <div type="grid">1 4 0 1 0</div> <div type="graph">1,3 2,3 1,1</div> <div>this has no type</div> </div> ''' div,div_end = makeHTMLTags("div") # only match div tag having a type attribute with value "grid" div_grid = div().setParseAction(withAttribute(type="grid")) grid_expr = div_grid + SkipTo(div | div_end)("body") for grid_header in grid_expr.searchString(html): print(grid_header.body) # construct a match with any div tag having a type attribute, regardless of the value div_any_type = div().setParseAction(withAttribute(type=withAttribute.ANY_VALUE)) div_expr = div_any_type + SkipTo(div | div_end)("body") for div_header in div_expr.searchString(html): print(div_header.body) prints:: 1 4 0 1 0 1 4 0 1 0 1,3 2,3 1,1 Nc S s g | ]\}}||f�qS rw rw )r� r� r� rw rw rx r� Q s z!withAttribute.<locals>.<listcomp>c s^ xX� D ]P\}}||kr&t | |d| ��|tjkr|| |krt | |d||| |f ��qW d S )Nzno matching attribute z+attribute '%s' has value '%s', must be '%s')r re � ANY_VALUE)r� r5 r� ZattrNameZ attrValue)�attrsrw rx r} R s zwithAttribute.<locals>.pa)r� )r� ZattrDictr} rw )r� rx re s 2 c C s |r d| nd}t f || i�S )a� Simplified version of C{L{withAttribute}} when matching on a div class - made difficult because C{class} is a reserved word in Python.

Operators may be unary or binary, left- or right-associative. Parse actions can also be attached to operator expressions. The generated parser will also recognize the use of parentheses to override operator precedences (see example below). Note: if you define a deep operator list, you may see performance issues when using infixNotation. See L{ParserElement.enablePackrat} for a mechanism to potentially improve your parser performance. Parameters: - baseExpr - expression representing the most basic element for the nested - opList - list of tuples, one for each operator precedence level in the expression grammar; each tuple is of the form (opExpr, numTerms, rightLeftAssoc, parseAction), where: - opExpr is the pyparsing expression for the operator; may also be a string, which will be converted to a Literal; if numTerms is 3, opExpr is a tuple of two expressions, for the two operators separating the 3 terms - numTerms is the number of terms for this operator (must be 1, 2, or 3) - rightLeftAssoc is the indicator whether the operator is right or left associative, using the pyparsing-defined constants C{opAssoc.RIGHT} and C{opAssoc.LEFT}. - parseAction is the parse action to be associated with expressions matching this operator expression (the parse action tuple member may be omitted) - lpar - expression for matching left-parentheses (default=C{Suppress('(')}) - rpar - expression for matching right-parentheses (default=C{Suppress(')')}) Example:: # simple example of four-function arithmetic with ints and variable names integer = pyparsing_common.signed_integer varname = pyparsing_common.identifier arith_expr = infixNotation(integer | varname, [ ('-', 1, opAssoc.RIGHT), (oneOf('* /'), 2, opAssoc.LEFT), (oneOf('+ -'), 2, opAssoc.LEFT), ]) arith_expr.runTests(''' 5+3*6 (5+3)*6 -2--11 ''', fullDump=False) prints:: 5+3*6 [[5, '+', [3, '*', 6]]] (5+3)*6 [[[5, '+', 3], '*', 6]] -2--11 [[['-', 2], '-', ['-', 11]]] Nr ro z%s termz %s%s termrq z@if numterms=3, opExpr must be a tuple or list of two expressionsrr z6operator must be unary (1), binary (2), or ternary (3)z2operator must indicate right or left associativity)N)r r� r� r� ri rT �LEFTr r r �RIGHTrz r r. r� )ZbaseExprZopListZlparZrparr� ZlastExprr� ZoperDefZopExprZarityZrightLeftAssocr} ZtermNameZopExpr1ZopExpr2ZthisExprrs rw rw rx ri � sR ; & & z4"(?:[^"\n\r\\]|(?:"")|(?:\\(?:[^x]|x[0-9a-fA-F]+)))*�"z string enclosed in double quotesz4'(?:[^'\n\r\\]|(?:'')|(?:\\(?:[^x]|x[0-9a-fA-F]+)))*�'z string enclosed in single quotesz*quotedString using single or double quotes�uzunicode string literalc C s� | |krt d��|dk�r(t| t�o,t|t��r t| �dkr�t|�dkr�|dk r�tt| t| | tj dd� ��j dd� �}n$t j � t| | tj �j dd� � }nx|dk r�tt| t | � t |� ttjdd� ��j dd� �}n4ttt | � t |� ttjdd� ��j d d� �}nt d ��t � }|dk �rb|tt| �t||B |B � t|� �K }n$|tt| �t||B � t|� �K }|jd | |f � |S ) a~ Helper method for defining nested lists enclosed in opening and closing delimiters ("(" and ")" are the default). Parameters: - opener - opening character for a nested list (default=C{"("}); can also be a pyparsing expression - closer - closing character for a nested list (default=C{")"}); can also be a pyparsing expression - content - expression for items within the nested lists (default=C{None}) - ignoreExpr - expression for ignoring opening and closing delimiters (default=C{quotedString}) If an expression is not provided for the content argument, the nested expression will capture all whitespace-delimited content between delimiters as a list of separate values. Use the C{ignoreExpr} argument to define expressions that may contain opening or closing characters that should not be treated as opening or closing characters for nesting, such as quotedString or a comment expression. Specify multiple expressions using an C{L{Or}} or C{L{MatchFirst}}. The default is L{quotedString}, but if no expressions are to be ignored, then pass C{None} for this argument. Example:: data_type = oneOf("void int short long char float double") decl_data_type = Combine(data_type + Optional(Word('*'))) ident = Word(alphas+'_', alphanums+'_') number = pyparsing_common.number arg = Group(decl_data_type + ident) LPAR,RPAR = map(Suppress, "()") code_body = nestedExpr('{', '}', ignoreExpr=(quotedString | cStyleComment)) c_function = (decl_data_type("type") + ident("name") + LPAR + Optional(delimitedList(arg), [])("args") + RPAR + code_body("body")) c_function.ignore(cStyleComment) source_code = ''' int is_odd(int x) { return (x%2); } int dec_to_hex(char hchar) { if (hchar >= '0' && hchar <= '9') { return (ord(hchar)-ord('0')); } else { return (10+ord(hchar)-ord('A')); } } ''' for func in c_function.searchString(source_code): print("%(name)s (%(type)s) args: %(args)s" % func) prints:: is_odd (int) args: [['int', 'x']] dec_to_hex (int) args: [['char', 'hchar']] z.opening and closing strings cannot be the sameNrr )r c S s | d j � S )Nr )r� )rv rw rw rx ry 9 s z nestedExpr.<locals>.<lambda>c S s | d j � S )Nr )r� )rv rw rw rx ry < s c S s | d j � S )Nr )r� )rv rw rw rx ry B s c S s | d j � S )Nr )r� )rv rw rw rx ry F s zOopening and closing arguments must be strings if no content expression is givenznested %s%s expression)r� rz r� r� r r r r$ rN r� rC r� r r r r+ r2 ri )�openerZcloserZcontentrO r� rw rw rx rP � s4 : *$c s� � fdd�}� fdd�}� fdd�}t t� jd�j� �}t� t� j|� jd�}t� j|�jd �}t� j|�jd �} |r�tt|�| t |t| � t|� � | �} n$tt|�t |t| � t|� � �} | j t t� � | jd �S ) a Helper method for defining space-delimited indentation blocks, such as those used to define block statements in Python source code. Parameters: - blockStatementExpr - expression defining syntax of statement that is repeated within the indented block - indentStack - list created by caller to manage indentation stack (multiple statementWithIndentedBlock expressions within a single grammar should share a common indentStack) - indent - boolean indicating whether block must be indented beyond the the current level; set to False for block of left-most statements (default=C{True}) A valid block must contain at least one C{blockStatement}. Example:: data = ''' def A(z): A1 B = 100 G = A2 A2 A3 B def BB(a,b,c): BB1 def BBA(): bba1 bba2 bba3 C D def spam(x,y): def eggs(z): pass ''' indentStack = [1] stmt = Forward() identifier =

OPINION: This function appends "Logs" to the `CSIDL_LOCAL_APPDATA` value for Windows and appends "log" to the user cache dir for Unix. This can be disabled with the `opinion=False` option. r z~/Library/Logsr FZLogs�log)r r r r r r r) )r r r r( r r r r � user_log_dir: s r+ c @ sb e Zd ZdZddd�Zedd� �Zedd � �Zed d � �Zed d � �Z edd� �Z edd� �Z dS )�AppDirsz1Convenience wrapper for getting application dirs.NFc C s" || _ || _|| _|| _|| _d S )N)r r r r r# )�selfr r r r r# r r r �__init__o s zAppDirs.__init__c C s t | j| j| j| jd�S )N)r r )r r r r r )r- r r r r w s zAppDirs.user_data_dirc C s t | j| j| j| jd�S )N)r r# )r% r r r r# )r- r r r r% | s zAppDirs.site_data_dirc C s t | j| j| j| jd�S )N)r r )r& r r r r )r- r r r r& � s zAppDirs.user_config_dirc C s t | j| j| j| jd�S )N)r r# )r' r r r r# )r- r r r r' � s zAppDirs.site_config_dirc C s t | j| j| jd�S )N)r )r) r r r )r- r r r r) � s zAppDirs.user_cache_dirc C s t | j| j| jd�S )N)r )r+ r r r )r- r r r r+ � s zAppDirs.user_log_dir)NNFF) �__name__� __module__� __qualname__�__doc__r. �propertyr r% r& r' r) r+ r r r r r, m s r, c C s: ddl }dddd�| }|j|jd�}|j||�\}}|S )z�This is a fallback technique at best.

With pyparsing, you don't need to learn a new syntax for defining grammars or matching expressions - the parsing module provides a library of classes that you use to construct the grammar directly in Python. Here is a program to parse "Hello, World!" (or any greeting of the form C{"<salutation>, <addressee>!"}), built up using L{Word}, L{Literal}, and L{And} elements (L{'+'<ParserElement.__add__>} operator gives L{And} expressions, strings are auto-converted to L{Literal} expressions):: from pyparsing import Word, alphas # define grammar of a greeting greet = Word(alphas) + "," + Word(alphas) + "!" hello = "Hello, World!" print (hello, "->", greet.parseString(hello)) The program outputs the following:: Hello, World! -> ['Hello', ',', 'World', '!'] The Python representation of the grammar is quite readable, owing to the self-explanatory class names, and the use of '+', '|' and '^' operators. The L{ParseResults} object returned from L{ParserElement.parseString<ParserElement.parseString>} can be accessed as a nested list, a dictionary, or an object with named attributes. The pyparsing module handles some of the problems that are typically vexing when writing text parsers: - extra or missing whitespace (the above program will also handle "Hello,World!", "Hello , World !", etc.) - quoted strings - embedded comments z2.1.10z07 Oct 2016 01:31 UTCz*Paul McGuire <ptmcg@users.sourceforge.net>� N)�ref)�datetime)�RLock)� OrderedDict�And�CaselessKeyword�CaselessLiteral� CharsNotIn�Combine�Dict�Each�Empty� FollowedBy�Forward� GoToColumn�Group�Keyword�LineEnd� LineStart�Literal� MatchFirst�NoMatch�NotAny� OneOrMore�OnlyOnce�Optional�Or�ParseBaseException�ParseElementEnhance�ParseException�ParseExpression�ParseFatalException� ParseResults�ParseSyntaxException� ParserElement� QuotedString�RecursiveGrammarException�Regex�SkipTo� StringEnd� StringStart�Suppress�Token�TokenConverter�White�Word�WordEnd� WordStart� ZeroOrMore� alphanums�alphas� alphas8bit� anyCloseTag� anyOpenTag� cStyleComment�col�commaSeparatedList�commonHTMLEntity� countedArray�cppStyleComment�dblQuotedString�dblSlashComment� delimitedList�dictOf�downcaseTokens�empty�hexnums� htmlComment�javaStyleComment�line�lineEnd� lineStart�lineno� makeHTMLTags� makeXMLTags�matchOnlyAtCol�matchPreviousExpr�matchPreviousLiteral� nestedExpr�nullDebugAction�nums�oneOf�opAssoc�operatorPrecedence� printables�punc8bit�pythonStyleComment� quotedString� removeQuotes�replaceHTMLEntity� replaceWith� restOfLine�sglQuotedString�srange� stringEnd� stringStart�traceParseAction� unicodeString� upcaseTokens� withAttribute� indentedBlock�originalTextFor�ungroup� infixNotation� locatedExpr� withClass� CloseMatch�tokenMap�pyparsing_common� c C s` t | t�r| S yt| �S tk rZ t| �jtj� d�}td�}|jdd� � |j |�S X dS )a Drop-in replacement for str(obj) that tries to be Unicode friendly.

A second default return value argument is supported, just as in C{dict.pop()}. Example:: def remove_first(tokens): tokens.pop(0) print(OneOrMore(Word(nums)).parseString("0 123 321")) # -> ['0', '123', '321'] print(OneOrMore(Word(nums)).addParseAction(remove_first).parseString("0 123 321")) # -> ['123', '321'] label = Word(alphas) patt = label("LABEL") + OneOrMore(Word(nums)) print(patt.parseString("AAB 123 321").dump()) # Use pop() in a parse action to remove named result (note that corresponding value is not # removed from list form of results) def remove_LABEL(tokens): tokens.pop("LABEL") return tokens patt.addParseAction(remove_LABEL) print(patt.parseString("AAB 123 321").dump()) prints:: ['AAB', '123', '321'] - LABEL: AAB ['AAB', '123', '321'] rr �defaultr z-pop() got an unexpected keyword argument '%s'Nrs )r� r� rz ru r� )r� r� �kwargsr� r� �indexr� Z defaultvaluerw rw rx �pop� s " zParseResults.popc C s || kr| | S |S dS )ai Returns named result matching the given key, or if there is no such name, then returns the given C{defaultValue} or C{None} if no C{defaultValue} is specified.

Parse action fn is a callable method with 0-3 arguments, called as C{fn(s,loc,toks)}, C{fn(loc,toks)}, C{fn(toks)}, or just C{fn()}, where: - s = the original string being parsed (see note below) - loc = the location of the matching substring - toks = a list of the matched tokens, packaged as a C{L{ParseResults}} object If the functions in fns modify the tokens, they can return them as the return value from fn, and the modified list of tokens will replace the original. Otherwise, fn does not need to return any value. Optional keyword arguments: - callDuringTry = (default=C{False}) indicate if parse action should be run during lookaheads and alternate testing Note: the default parsing behavior is to expand tabs in the input string before starting the parsing process. See L{I{parseString}<parseString>} for more information on parsing strings containing C{<TAB>}s, and suggested methods to maintain a consistent view of the parsed string, the parse location, and line and column positions within the parsed string. Example:: integer = Word(nums) date_str = integer + '/' + integer + '/' + integer date_str.parseString("1999/12/31") # -> ['1999', '/', '12', '/', '31'] # use parse action to convert to ints at parse time integer = Word(nums).setParseAction(lambda toks: int(toks[0])) date_str = integer + '/' + integer + '/' + integer # note that integer fields are now ints, not strings date_str.parseString("1999/12/31") # -> [1999, '/', 12, '/', 31] rf F)r� �maprM rS r� rf )r� �fnsr� rw rw rx r� � s "z ParserElement.setParseActionc O s4 | j tttt|���7 _ | jp,|jdd�| _| S )z� Add parse action to expression's list of parse actions.

Repeated parse attempts at the same string location (which happens often in many complex grammars) can immediately return a cached value, instead of re-executing parsing/validating code. Memoizing is done of both valid results and parsing exceptions. Parameters: - cache_size_limit - (default=C{128}) - if an integer value is provided will limit the size of the packrat cache; if None is passed, then the cache size will be unbounded; if 0 is passed, the cache will be effectively disabled. This speedup may break existing programs that use parse actions that have side-effects. For this reason, packrat parsing is disabled when you first import pyparsing. To activate the packrat feature, your program must call the class method C{ParserElement.enablePackrat()}. If your program uses C{psyco} to "compile as you go", you must call C{enablePackrat} before calling C{psyco.full()}. If you do not do this, Python will crash. For best results, call C{enablePackrat()} immediately after importing pyparsing. Example:: import pyparsing pyparsing.ParserElement.enablePackrat() TN)r$ �_packratEnabledr� r� r� r� rt )Zcache_size_limitrw rw rx � enablePackrat s zParserElement.enablePackratc C s� t j� | js| j� x| jD ] }|j� q W | js<|j� }y<| j|d�\}}|rv| j||�}t � t � }|j||� W n0 t k r� } zt j r�� n|�W Y dd}~X nX |S dS )aB Execute the parse expression with the given string. This is the main interface to the client code, once the complete expression has been built. If you want the grammar to require that the entire input string be successfully parsed, then set C{parseAll} to True (equivalent to ending the grammar with C{L{StringEnd()}}). Note: C{parseString} implicitly calls C{expandtabs()} on the input string, in order to report proper column numbers in parse actions. If the input string contains tabs and the grammar uses parse actions that use the C{loc} argument to index into the string being parsed, you can ensure you have a consistent view of the input string by: - calling C{parseWithTabs} on your grammar before calling C{parseString} (see L{I{parseWithTabs}<parseWithTabs>}) - define your parse action using the full C{(s,loc,toks)} signature, and reference the input string using the parse action's C{s} argument - explictly expand the tabs in your input string before calling C{parseString} Example:: Word('a').parseString('aaaaabaaa') # -> ['aaaaa'] Word('a').parseString('aaaaabaaa', parseAll=True) # -> Exception: Expected end of text r N) r$ r� r_ � streamliner] r\ � expandtabsrt r� r r) r �verbose_stacktrace)r� r- �parseAllr� r� r� Zser3 rw rw rx � parseString# s$ zParserElement.parseStringc c s@ | j s| j� x| jD ] }|j� qW | js8t|�j� }t|�}d}| j}| j}t j � d} y�x�||kon| |k �ry |||�} ||| dd�\} } W n t k r� | d }Y q`X | |kr�| d7 } | | | fV |r�|||�} | |kr�| }q�|d7 }n| }q`| d }q`W W n4 t k �r: } zt j �r&� n|�W Y dd}~X nX dS )a� Scan the input string for expression matches. Each match will return the matching tokens, start location, and end location. May be called with optional C{maxMatches} argument, to clip scanning after 'n' matches are found. If C{overlap} is specified, then overlapping matches will be reported. Note that the start and end locations are reported relative to the string being parsed. See L{I{parseString}<parseString>} for more information on parsing strings with embedded tabs. Example:: source = "sldjf123lsdjjkf345sldkjf879lkjsfd987" print(source) for tokens,start,end in Word(alphas).scanString(source): print(' '*start + '^'*(end-start)) print(' '*start + tokens[0]) prints:: sldjf123lsdjjkf345sldkjf879lkjsfd987 ^^^^^ sldjf ^^^^^^^ lsdjjkf ^^^^^^ sldkjf ^^^^^^ lkjsfd r F)rp rr N)r_ r� r] r\ r� r� r� r� rt r$ r� r r r� )r� r- � maxMatchesZoverlapr� r� r� Z preparseFnZparseFn�matchesr� ZnextLocr� Znextlocr3 rw rw rx � scanStringU sB zParserElement.scanStringc C s� g }d}d| _ y�xh| j|�D ]Z\}}}|j|||� � |rrt|t�rT||j� 7 }n t|t�rh||7 }n |j|� |}q W |j||d� � dd� |D �}djtt t |���S t k r� } zt j rȂ n|�W Y dd}~X nX dS )af Extension to C{L{scanString}}, to modify matching text with modified tokens that may be returned from a parse action. To use C{transformString}, define a grammar and attach a parse action to it that modifies the returned token list. Invoking C{transformString()} on a target string will then scan for matches, and replace the matched text patterns according to the logic in the parse action. C{transformString()} returns the resulting transformed string. Example:: wd = Word(alphas) wd.setParseAction(lambda toks: toks[0].title()) print(wd.transformString("now is the winter of our discontent made glorious summer by this sun of york.")) Prints:: Now Is The Winter Of Our Discontent Made Glorious Summer By This Sun Of York. r TNc S s g | ] }|r|�qS rw rw )r� �orw rw rx r� � s z1ParserElement.transformString.<locals>.<listcomp>r� )r\ r� r� rz r" r� r� r� rv r� �_flattenr r$ r� )r� r- r ZlastErv r� r� r3 rw rw rx r� � s( z ParserElement.transformStringc C sP yt dd� | j||�D ��S tk rJ } ztjr6� n|�W Y dd}~X nX dS )a~ Another extension to C{L{scanString}}, simplifying the access to the tokens found to match the given parse expression.

Example:: punc = oneOf(list(".,;:/-!?")) print(list(punc.split("This, this?, this sentence, is badly punctuated!"))) prints:: ['This', ' this', '', ' this sentence', ' is badly punctuated', ''] r )r� N)r� ) r� r- �maxsplitZincludeSeparatorsZsplitsZlastrv r� r� rw rw rx r� � s zParserElement.splitc C sF t |t�rtj|�}t |t�s:tjdt|� tdd� dS t| |g�S )a� Implementation of + operator - returns C{L{And}}.

Quick and easy way to run a parse expression against a list of sample strings. Parameters: - tests - a list of separate test strings, or a multiline string of test strings - parseAll - (default=C{True}) - flag to pass to C{L{parseString}} when running tests - comment - (default=C{'#'}) - expression for indicating embedded comments in the test string; pass None to disable comment filtering - fullDump - (default=C{True}) - dump results as list followed by results names in nested outline; if False, only dump nested list - printResults - (default=C{True}) prints test output to stdout - failureTests - (default=C{False}) indicates if these tests are expected to fail parsing Returns: a (success, results) tuple, where success indicates that all tests succeeded (or failed if C{failureTests} is True), and the results contain a list of lines of each test's output Example:: number_expr = pyparsing_common.number.copy() result = number_expr.runTests(''' # unsigned integer 100 # negative integer -100 # float with scientific notation 6.02e23 # integer with scientific notation 1e-12 ''') print("Success" if result[0] else "Failed!") result = number_expr.runTests(''' # stray character 100Z # missing leading digit before '.' -.100 # too many '.' 3.14.159 ''', failureTests=True) print("Success" if result[0] else "Failed!") prints:: # unsigned integer 100 [100] # negative integer -100 [-100] # float with scientific notation 6.02e23 [6.02e+23] # integer with scientific notation 1e-12 [1e-12] Success # stray character 100Z ^ FAIL: Expected end of text (at char 3), (line:1, col:4) # missing leading digit before '.' -.100 ^ FAIL: Expected {real number with scientific notation | real number | signed integer} (at char 0), (line:1, col:1) # too many '.' 3.14.159 ^ FAIL: Expected end of text (at char 4), (line:1, col:5) Success Each test string must be on a single line. If you want to test a string that spans multiple lines, create a test like this:: expr.runTest(r"this is a test\n of strings that spans \n 3 lines") (Note that this is a raw string literal, you must include the leading 'r'.)

C{CloseMatch} takes parameters: - C{match_string} - string to be matched - C{maxMismatches} - (C{default=1}) maximum number of mismatches allowed to count as a match The results from a successful parse will contain the matched text from the input string and the following named results: - C{mismatches} - a list of the positions within the match_string where mismatches were found - C{original} - the original match_string used to compare against the input string If C{mismatches} is an empty list, then the match was an exact match. Example:: patt = CloseMatch("ATCATCGAATGGA") patt.parseString("ATCATCGAAXGGA") # -> (['ATCATCGAAXGGA'], {'mismatches': [[9]], 'original': ['ATCATCGAATGGA']}) patt.parseString("ATCAXCGAAXGGA") # -> Exception: Expected 'ATCATCGAATGGA' (with up to 1 mismatches) (at char 0), (line:1, col:1) # exact match patt.parseString("ATCATCGAATGGA") # -> (['ATCATCGAATGGA'], {'mismatches': [[]], 'original': ['ATCATCGAATGGA']}) # close match allowing up to 2 mismatches patt = CloseMatch("ATCATCGAATGGA", maxMismatches=2) patt.parseString("ATCAXCGAAXGGA") # -> (['ATCAXCGAAXGGA'], {'mismatches': [[4, 9]], 'original': ['ATCATCGAATGGA']}) rr c sB t t| �j� || _|| _|| _d| j| jf | _d| _d| _d S )Nz&Expected %r (with up to %d mismatches)F) r� rl r� r� � match_string� maxMismatchesra r` r[ )r� r� r� )rH rw rx r� � s zCloseMatch.__init__Tc C s� |}t |�}|t | j� }||kr�| j}d}g } | j} x�tt|||� | j��D ]0\}} | \} } | | krP| j|� t | �| krPP qPW |d }t|||� g�}| j|d< | |d< ||fS t||| j| ��d S )Nr rr �original� mismatches) r� r� r� r� r� r� r" r ra )r� r- r� ro �startr� �maxlocr� Zmatch_stringlocr� r� Zs_m�src�mat�resultsrw rw rx r� � s( " zCloseMatch.parseImpl)rr )T)r� r� r� r� r� r� r� rw rw )rH rx rl � s c s8 e Zd ZdZd � fdd� Zdd d �Z� fd d �Z� ZS )r/ a Token for matching words composed of allowed character sets. Defined with string containing all allowed initial characters, an optional string containing allowed body characters (if omitted, defaults to the initial character set), and an optional minimum, maximum, and/or exact length. The default value for C{min} is 1 (a minimum value < 1 is not valid); the default values for C{max} and C{exact} are 0, meaning no maximum or exact length restriction. An optional C{excludeChars} parameter can list characters that might be found in the input C{bodyChars} string; useful to define a word of all printables except for one or two characters, for instance. L{srange} is useful for defining custom character set strings for defining C{Word} expressions, using range notation from regular expression character sets. A common mistake is to use C{Word} to match a specific literal string, as in C{Word("Address")}. Remember that C{Word} uses the string argument to define I{sets} of matchable characters. This expression would match "Add", "AAA", "dAred", or any other word made up of the characters 'A', 'd', 'r', 'e', and 's'. To match an exact literal string, use L{Literal} or L{Keyword}. pyparsing includes helper strings for building Words: - L{alphas} - L{nums} - L{alphanums} - L{hexnums} - L{alphas8bit} (alphabetic characters in ASCII range 128-255 - accented, tilded, umlauted, etc.) - L{punc8bit} (non-alphabetic characters in ASCII range 128-255 - currency, symbols, superscripts, diacriticals, etc.) - L{printables} (any non-whitespace character) Example:: # a word composed of digits integer = Word(nums) # equivalent to Word("0123456789") or Word(srange("0-9")) # a word with a leading capital, and zero or more lowercase capital_word = Word(alphas.upper(), alphas.lower()) # hostnames are alphanumeric, with leading alpha, and '-' hostname = Word(alphas, alphanums+'-') # roman numeral (not a strict parser, accepts invalid mix of characters) roman = Word("IVXLCDM") # any string of non-whitespace characters, except for ',' csv_value = Word(printables, excludeChars=",") Nrr r Fc s� t t| �j� � rFdj� fdd�|D ��}|rFdj� fdd�|D ��}|| _t|�| _|rl|| _t|�| _n|| _t|�| _|dk| _ |dk r�t d��|| _ |dkr�|| _ nt | _ |dkr�|| _ || _ t| �| _d| j | _d | _|| _d | j| j k�r�|dk�r�|dk�r�|dk�r�| j| jk�r8d t| j� | _nHt| j�dk�rfd tj| j�t| j�f | _nd t| j�t| j�f | _| j�r�d| j d | _ytj| j�| _W n tk �r� d | _Y nX d S )Nr� c 3 s | ]}|� kr|V qd S )Nrw )r� r� )� excludeCharsrw rx r� 7 s z Word.__init__.<locals>.<genexpr>c 3 s | ]}|� kr|V qd S )Nrw )r� r� )r� rw rx r� 9 s r rr zZcannot specify a minimum length < 1; use Optional(Word()) if zero-length word is permittedz Expected Fr� z[%s]+z%s[%s]*z [%s][%s]*z\b)r� r/ r� r� � initCharsOrigr� � initChars� bodyCharsOrig� bodyChars� maxSpecifiedr� �minLen�maxLenr� r� r� ra r` � asKeyword�_escapeRegexRangeChars�reStringr� rd �escape�compilerK )r� r r �min�max�exactr r� )rH )r� rx r� 4 sT 0 z Word.__init__Tc C sD | j r<| j j||�}|s(t||| j| ��|j� }||j� fS || | jkrZt||| j| ��|}|d7 }t|�}| j}|| j }t ||�}x ||k r�|| |kr�|d7 }q�W d} || | j k r�d} | j r�||k r�|| |kr�d} | j �r |dk�r||d |k�s||k �r || |k�r d} | �r4t||| j| ��||||� fS )Nrr FTr )rd r� r ra �end�groupr r� r r r r r r ) r� r- r� ro r� r� r� Z bodycharsr� ZthrowExceptionrw rw rx r� j s6 4zWord.parseImplc st yt t| �j� S tk r" Y nX | jd krndd� }| j| jkr^d|| j�|| j�f | _nd|| j� | _| jS )Nc S s$ t | �dkr | d d� d S | S d S )N� z...)r� )r� rw rw rx � charsAsStr� s z Word.__str__.<locals>.charsAsStrz W:(%s,%s)zW:(%s))r� r/ r� rK rU r� r )r� r )rH rw rx r� � s z Word.__str__)Nrr r r FN)T)r� r� r� r� r� r� r� r� rw rw )rH rx r/ s .6 #c sF e Zd ZdZeejd��Zd � fdd� Zd dd�Z � fd d �Z � Z S ) r' a� Token for matching strings that match a given regular expression.

Also takes optional C{min}, C{max}, and C{exact} arguments, as defined for the C{L{Word}} class. z<SPC>z<TAB>z<LF>z<CR>z<FF>)r� r( r r* r) � rr r c s� t t� �j� |� _� jdj� fdd�� jD ��� djdd� � jD ��� _d� _d� j � _ |� _ |dkrt|� _ nt � _ |dkr�|� _ |� _ d S )Nr� c 3 s | ]}|� j kr|V qd S )N)� matchWhite)r� r� )r� rw rx r� � s z!White.__init__.<locals>.<genexpr>c s s | ]}t j| V qd S )N)r. � whiteStrs)r� r� rw rw rx r� � s Tz Expected r ) r� r. r� r. r� r� rY r� r[ ra r r r� )r� Zwsr r r )rH )r� rx r� � s zWhite.__init__Tc C s� || | j kr t||| j| ��|}|d7 }|| j }t|t|��}x"||k rd|| | j krd|d7 }qDW || | jk r�t||| j| ��||||� fS )Nrr )r. r ra r r r� r )r� r- r� ro r� r� rw rw rx r� � s zWhite.parseImpl)r- rr r r )T)r� r� r� r� r/ r� r� r� rw rw )rH rx r. � s c s e Zd Z� fdd�Z� ZS )�_PositionTokenc s( t t| �j� | jj| _d| _d| _d S )NTF)r� r0 r� rH r� r� r[ r` )r� )rH rw rx r� � s z_PositionToken.__init__)r� r� r� r� r� rw rw )rH rx r0 � s r0 c s2 e Zd ZdZ� fdd�Zdd� Zd dd�Z� ZS ) r zb Token to advance to a specific column of input text; useful for tabular report scraping. c s t t| �j� || _d S )N)r� r r� r9 )r� �colno)rH rw rx r� � s zGoToColumn.__init__c C s` t ||�| j kr\t|�}| jr*| j||�}x0||k rZ|| j� rZt ||�| j krZ|d7 }q,W |S )Nrr )r9 r� r] r� �isspace)r� r- r� r� rw rw rx r� � s & zGoToColumn.preParseTc C sD t ||�}|| j kr"t||d| ��|| j | }|||� }||fS )NzText not in expected column)r9 r )r� r- r� ro ZthiscolZnewlocr� rw rw rx r� s zGoToColumn.parseImpl)T)r� r� r� r� r� r� r� r� rw rw )rH rx r � s c s* e Zd ZdZ� fdd�Zddd�Z� ZS )r a� Matches if current position is at the beginning of a line within the parse string Example:: test = ''' AAA this line AAA and this line AAA but not this one B AAA and definitely not this one ''' for t in (LineStart() + 'AAA' + restOfLine).searchString(test): print(t) Prints:: ['AAA', ' this line'] ['AAA', ' and this line'] c s t t| �j� d| _d S )NzExpected start of line)r� r r� ra )r� )rH rw rx r� & s zLineStart.__init__Tc C s* t ||�dkr|g fS t||| j| ��d S )Nrr )r9 r ra )r� r- r� ro rw rw rx r� * s zLineStart.parseImpl)T)r� r� r� r� r� r� r� rw rw )rH rx r s c s* e Zd ZdZ� fdd�Zddd�Z� ZS )r zU Matches if current position is at the end of a line within the parse string c s, t t| �j� | jtjjdd�� d| _d S )Nr r� zExpected end of line)r� r r� r� r$ rN r� ra )r� )rH rw rx r� 3 s zLineEnd.__init__Tc C sb |t |�k r6|| dkr$|d dfS t||| j| ��n(|t |�krN|d g fS t||| j| ��d S )Nr rr )r� r ra )r� r- r� ro rw rw rx r� 8 s zLineEnd.parseImpl)T)r� r� r� r� r� r� r� rw rw )rH rx r / s c s* e Zd ZdZ� fdd�Zddd�Z� ZS )r* zM Matches if current position is at the beginning of the parse string c s t t| �j� d| _d S )NzExpected start of text)r� r* r� ra )r� )rH rw rx r� G s zStringStart.__init__Tc C s0 |dkr(|| j |d�kr(t||| j| ��|g fS )Nr )r� r ra )r� r- r� ro rw rw rx r� K s zStringStart.parseImpl)T)r� r� r� r� r� r� r� rw rw )rH rx r* C s c s* e Zd ZdZ� fdd�Zddd�Z� ZS )r) zG Matches if current position is at the end of the parse string c s t t| �j� d| _d S )NzExpected end of text)r� r) r� ra )r� )rH rw rx r� V s zStringEnd.__init__Tc C s^ |t |�k r t||| j| ��n<|t |�kr6|d g fS |t |�krJ|g fS t||| j| ��d S )Nrr )r� r ra )r� r- r� ro rw rw rx r� Z s zStringEnd.parseImpl)T)r� r� r� r� r� r� r� rw rw )rH rx r) R s c s. e Zd ZdZef� fdd� Zddd�Z� ZS )r1 ap Matches if the current position is at the beginning of a Word, and is not preceded by any character in a given set of C{wordChars} (default=C{printables}).

When the expression is known, it is assigned to the C{Forward} variable using the '<<' operator. Note: take care when assigning to C{Forward} not to overlook precedence of operators. Specifically, '|' has a lower precedence than '<<', so that:: fwdExpr << a | b | c will actually be evaluated as:: (fwdExpr << a) | b | c thereby leaving b and c out as parseable alternatives. It is recommended that you explicitly group the values inserted into the C{Forward}:: fwdExpr << (a | b | c) Converting to use the '<<=' operator instead will avoid this problem. See L{ParseResults.pprint} for an example of a recursive parser created using C{Forward}.

Example:: text = "shape: SQUARE posn: upper left color: light blue texture: burlap" attr_expr = (label + Suppress(':') + OneOrMore(data_word, stopOn=label).setParseAction(' '.join)) print(OneOrMore(attr_expr).parseString(text).dump()) attr_label = label attr_value = Suppress(':') + OneOrMore(data_word, stopOn=label).setParseAction(' '.join) # similar to Dict, but simpler call format result = dictOf(attr_label, attr_value).parseString(text) print(result.dump()) print(result['shape']) print(result.shape) # object attribute access works too print(result.asDict()) prints:: [['shape', 'SQUARE'], ['posn', 'upper left'], ['color', 'light blue'], ['texture', 'burlap']] - color: light blue - posn: upper left - shape: SQUARE - texture: burlap SQUARE SQUARE {'color': 'light blue', 'shape': 'SQUARE', 'posn': 'upper left', 'texture': 'burlap'} )r r2 r )r� r� rw rw rx rA � s !c C s^ t � jdd� �}|j� }d|_|d�| |d� }|r@dd� }ndd� }|j|� | j|_|S ) a� Helper to return the original, untokenized text for a given expression. Useful to restore the parsed fields of an HTML start tag into the raw tag text itself, or to revert separate tokens with intervening whitespace back to the original matching input text. By default, returns astring containing the original parsed text. If the optional C{asString} argument is passed as C{False}, then the return value is a C{L{ParseResults}} containing any results names that were originally matched, and a single token containing the original matched text from the input string. So if the expression passed to C{L{originalTextFor}} contains expressions with defined results names, you must set C{asString} to C{False} if you want to preserve those results name values. Example:: src = "this is test <b> bold <i>text</i> </b> normal text " for tag in ("b","i"): opener,closer = makeHTMLTags(tag) patt = originalTextFor(opener + SkipTo(closer) + closer) print(patt.searchString(src)[0]) prints:: ['<b> bold <i>text</i> </b>'] ['<i>text</i>'] c S s |S )Nrw )r� r� rv rw rw rx ry 8 s z!originalTextFor.<locals>.<lambda>F�_original_start� _original_endc S s | |j |j� S )N)rp rq )r� r5 rv rw rw rx ry = s c S s& | |j d�|j d�� g|d d �< d S )Nrp rq )r� )r� r5 rv rw rw rx � extractText? s z$originalTextFor.<locals>.extractText)r r� r� re r] )r.

Borrows syntax from regexp '[]' string range definitions:: srange("[0-9]") -> "0123456789" srange("[a-z]") -> "abcdefghijklmnopqrstuvwxyz" srange("[a-z$_]") -> "abcdefghijklmnopqrstuvwxyz$_" The input string must be enclosed in []'s, and the returned string is the expanded character set joined into a single string. The values enclosed in the []'s may be: - a single character - an escaped character with a leading backslash (such as C{\-} or C{\]}) - an escaped hex character with a leading C{'\x'} (C{\x21}, which is a C{'!'} character) (C{\0x##} is also supported for backwards compatibility) - an escaped octal character with a leading C{'\0'} (C{\041}, which is a C{'!'} character) - a range of any of the above, separated by a dash (C{'a-z'}, etc.) - any combination of the above (C{'aeiouy'}, C{'a-zA-Z0-9_$'}, etc.) c S s< t | t�s| S djdd� tt| d �t| d �d �D ��S )Nr� c s s | ]}t |�V qd S )N)ru )r� r� rw rw rx r� � s z+srange.<locals>.<lambda>.<locals>.<genexpr>r rr )rz r" r� r� �ord)�prw rw rx ry � s zsrange.<locals>.<lambda>r� c 3 s | ]}� |�V qd S )Nrw )r� �part)� _expandedrw rx r� � s zsrange.<locals>.<genexpr>N)r� �_reBracketExprr� rx rK )r� rw )r| rx r_ r s c s � fdd�}|S )zt Helper method for defining parse actions that require matching at a specific column in the input text. c s" t || �� kr t| |d� ��d S )Nz matched token not at column %d)r9 r )r) Zlocnr1 )r� rw rx � verifyCol� s z!matchOnlyAtCol.<locals>.verifyColrw )r� r~ rw )r� rx rM � s c s � fdd�S )a� Helper method for common parse actions that simply return a literal value.

Use C{withAttribute} to qualify a starting tag with a required attribute value, to avoid false matches on common tags such as C{<TD>} or C{<DIV>}. Call C{withAttribute} with a series of attribute names and values. Specify the list of filter attributes names and values as: - keyword arguments, as in C{(align="right")}, or - as an explicit dict with C{**} operator, when an attribute name is also a Python reserved word, as in C{**{"class":"Customer", "align":"right"}} - a list of name-value tuples, as in ( ("ns1:class", "Customer"), ("ns2:align","right") ) For attribute names with a namespace prefix, you must use the second form. Attribute names are matched insensitive to upper/lower case. If just testing for C{class} (with or without a namespace), use C{L{withClass}}. To verify that the attribute exists, but without specifying a value, pass C{withAttribute.ANY_VALUE} as the value. Example:: html = ''' <div> Some text <div type="grid">1 4 0 1 0</div> <div type="graph">1,3 2,3 1,1</div> <div>this has no type</div> </div> ''' div,div_end = makeHTMLTags("div") # only match div tag having a type attribute with value "grid" div_grid = div().setParseAction(withAttribute(type="grid")) grid_expr = div_grid + SkipTo(div | div_end)("body") for grid_header in grid_expr.searchString(html): print(grid_header.body) # construct a match with any div tag having a type attribute, regardless of the value div_any_type = div().setParseAction(withAttribute(type=withAttribute.ANY_VALUE)) div_expr = div_any_type + SkipTo(div | div_end)("body") for div_header in div_expr.searchString(html): print(div_header.body) prints:: 1 4 0 1 0 1 4 0 1 0 1,3 2,3 1,1 Nc S s g | ]\}}||f�qS rw rw )r� r� r� rw rw rx r� Q s z!withAttribute.<locals>.<listcomp>c s^ xX� D ]P\}}||kr&t | |d| ��|tjkr|| |krt | |d||| |f ��qW d S )Nzno matching attribute z+attribute '%s' has value '%s', must be '%s')r re � ANY_VALUE)r� r5 r� ZattrNameZ attrValue)�attrsrw rx r} R s zwithAttribute.<locals>.pa)r� )r� ZattrDictr} rw )r� rx re s 2 c C s |r d| nd}t f || i�S )a� Simplified version of C{L{withAttribute}} when matching on a div class - made difficult because C{class} is a reserved word in Python.

Operators may be unary or binary, left- or right-associative. Parse actions can also be attached to operator expressions. The generated parser will also recognize the use of parentheses to override operator precedences (see example below). Note: if you define a deep operator list, you may see performance issues when using infixNotation. See L{ParserElement.enablePackrat} for a mechanism to potentially improve your parser performance. Parameters: - baseExpr - expression representing the most basic element for the nested - opList - list of tuples, one for each operator precedence level in the expression grammar; each tuple is of the form (opExpr, numTerms, rightLeftAssoc, parseAction), where: - opExpr is the pyparsing expression for the operator; may also be a string, which will be converted to a Literal; if numTerms is 3, opExpr is a tuple of two expressions, for the two operators separating the 3 terms - numTerms is the number of terms for this operator (must be 1, 2, or 3) - rightLeftAssoc is the indicator whether the operator is right or left associative, using the pyparsing-defined constants C{opAssoc.RIGHT} and C{opAssoc.LEFT}. - parseAction is the parse action to be associated with expressions matching this operator expression (the parse action tuple member may be omitted) - lpar - expression for matching left-parentheses (default=C{Suppress('(')}) - rpar - expression for matching right-parentheses (default=C{Suppress(')')}) Example:: # simple example of four-function arithmetic with ints and variable names integer = pyparsing_common.signed_integer varname = pyparsing_common.identifier arith_expr = infixNotation(integer | varname, [ ('-', 1, opAssoc.RIGHT), (oneOf('* /'), 2, opAssoc.LEFT), (oneOf('+ -'), 2, opAssoc.LEFT), ]) arith_expr.runTests(''' 5+3*6 (5+3)*6 -2--11 ''', fullDump=False) prints:: 5+3*6 [[5, '+', [3, '*', 6]]] (5+3)*6 [[[5, '+', 3], '*', 6]] -2--11 [[['-', 2], '-', ['-', 11]]] Nr ro z%s termz %s%s termrq z@if numterms=3, opExpr must be a tuple or list of two expressionsrr z6operator must be unary (1), binary (2), or ternary (3)z2operator must indicate right or left associativity)N)r r� r� r� ri rT �LEFTr r r �RIGHTrz r r. r� )ZbaseExprZopListZlparZrparr� ZlastExprr� ZoperDefZopExprZarityZrightLeftAssocr} ZtermNameZopExpr1ZopExpr2ZthisExprrs rw rw rx ri � sR ; & & z4"(?:[^"\n\r\\]|(?:"")|(?:\\(?:[^x]|x[0-9a-fA-F]+)))*�"z string enclosed in double quotesz4'(?:[^'\n\r\\]|(?:'')|(?:\\(?:[^x]|x[0-9a-fA-F]+)))*�'z string enclosed in single quotesz*quotedString using single or double quotes�uzunicode string literalc C s� | |krt d��|dk�r(t| t�o,t|t��r t| �dkr�t|�dkr�|dk r�tt| t| | tj dd� ��j dd� �}n$t j � t| | tj �j dd� � }nx|dk r�tt| t | � t |� ttjdd� ��j dd� �}n4ttt | � t |� ttjdd� ��j d d� �}nt d ��t � }|dk �rb|tt| �t||B |B � t|� �K }n$|tt| �t||B � t|� �K }|jd | |f � |S ) a~ Helper method for defining nested lists enclosed in opening and closing delimiters ("(" and ")" are the default). Parameters: - opener - opening character for a nested list (default=C{"("}); can also be a pyparsing expression - closer - closing character for a nested list (default=C{")"}); can also be a pyparsing expression - content - expression for items within the nested lists (default=C{None}) - ignoreExpr - expression for ignoring opening and closing delimiters (default=C{quotedString}) If an expression is not provided for the content argument, the nested expression will capture all whitespace-delimited content between delimiters as a list of separate values. Use the C{ignoreExpr} argument to define expressions that may contain opening or closing characters that should not be treated as opening or closing characters for nesting, such as quotedString or a comment expression. Specify multiple expressions using an C{L{Or}} or C{L{MatchFirst}}. The default is L{quotedString}, but if no expressions are to be ignored, then pass C{None} for this argument. Example:: data_type = oneOf("void int short long char float double") decl_data_type = Combine(data_type + Optional(Word('*'))) ident = Word(alphas+'_', alphanums+'_') number = pyparsing_common.number arg = Group(decl_data_type + ident) LPAR,RPAR = map(Suppress, "()") code_body = nestedExpr('{', '}', ignoreExpr=(quotedString | cStyleComment)) c_function = (decl_data_type("type") + ident("name") + LPAR + Optional(delimitedList(arg), [])("args") + RPAR + code_body("body")) c_function.ignore(cStyleComment) source_code = ''' int is_odd(int x) { return (x%2); } int dec_to_hex(char hchar) { if (hchar >= '0' && hchar <= '9') { return (ord(hchar)-ord('0')); } else { return (10+ord(hchar)-ord('A')); } } ''' for func in c_function.searchString(source_code): print("%(name)s (%(type)s) args: %(args)s" % func) prints:: is_odd (int) args: [['int', 'x']] dec_to_hex (int) args: [['char', 'hchar']] z.opening and closing strings cannot be the sameNrr )r c S s | d j � S )Nr )r� )rv rw rw rx ry 9 s z nestedExpr.<locals>.<lambda>c S s | d j � S )Nr )r� )rv rw rw rx ry < s c S s | d j � S )Nr )r� )rv rw rw rx ry B s c S s | d j � S )Nr )r� )rv rw rw rx ry F s zOopening and closing arguments must be strings if no content expression is givenznested %s%s expression)r� rz r� r� r r r r$ rN r� rC r� r r r r+ r2 ri )�openerZcloserZcontentrO r� rw rw rx rP � s4 : *$c s� � fdd�}� fdd�}� fdd�}t t� jd�j� �}t� t� j|� jd�}t� j|�jd �}t� j|�jd �} |r�tt|�| t |t| � t|� � | �} n$tt|�t |t| � t|� � �} | j t t� � | jd �S ) a Helper method for defining space-delimited indentation blocks, such as those used to define block statements in Python source code. Parameters: - blockStatementExpr - expression defining syntax of statement that is repeated within the indented block - indentStack - list created by caller to manage indentation stack (multiple statementWithIndentedBlock expressions within a single grammar should share a common indentStack) - indent - boolean indicating whether block must be indented beyond the the current level; set to False for block of left-most statements (default=C{True}) A valid block must contain at least one C{blockStatement}.

With pyparsing, you don't need to learn a new syntax for defining grammars or matching expressions - the parsing module provides a library of classes that you use to construct the grammar directly in Python. Here is a program to parse "Hello, World!" (or any greeting of the form C{"<salutation>, <addressee>!"}), built up using L{Word}, L{Literal}, and L{And} elements (L{'+'<ParserElement.__add__>} operator gives L{And} expressions, strings are auto-converted to L{Literal} expressions):: from pyparsing import Word, alphas # define grammar of a greeting greet = Word(alphas) + "," + Word(alphas) + "!" hello = "Hello, World!" print (hello, "->", greet.parseString(hello)) The program outputs the following:: Hello, World! -> ['Hello', ',', 'World', '!'] The Python representation of the grammar is quite readable, owing to the self-explanatory class names, and the use of '+', '|' and '^' operators. The L{ParseResults} object returned from L{ParserElement.parseString<ParserElement.parseString>} can be accessed as a nested list, a dictionary, or an object with named attributes. The pyparsing module handles some of the problems that are typically vexing when writing text parsers: - extra or missing whitespace (the above program will also handle "Hello,World!", "Hello , World !", etc.) - quoted strings - embedded comments """ __version__ = "2.1.10" __versionTime__ = "07 Oct 2016 01:31 UTC" __author__ = "Paul McGuire <ptmcg@users.sourceforge.net>" import string from weakref import ref as wkref import copy import sys import warnings import re import sre_constants import collections import pprint import traceback import types from datetime import datetime try: from _thread import RLock except ImportError: from threading import RLock try: from collections import OrderedDict as _OrderedDict except ImportError: try: from ordereddict import OrderedDict as _OrderedDict except ImportError: _OrderedDict = None #~ sys.stderr.write( "testing pyparsing module, version %s, %s\n" % (__version__,__versionTime__ ) ) __all__ = [ 'And', 'CaselessKeyword', 'CaselessLiteral', 'CharsNotIn', 'Combine', 'Dict', 'Each', 'Empty', 'FollowedBy', 'Forward', 'GoToColumn', 'Group', 'Keyword', 'LineEnd', 'LineStart', 'Literal', 'MatchFirst', 'NoMatch', 'NotAny', 'OneOrMore', 'OnlyOnce', 'Optional', 'Or', 'ParseBaseException', 'ParseElementEnhance', 'ParseException', 'ParseExpression', 'ParseFatalException', 'ParseResults', 'ParseSyntaxException', 'ParserElement', 'QuotedString', 'RecursiveGrammarException', 'Regex', 'SkipTo', 'StringEnd', 'StringStart', 'Suppress', 'Token', 'TokenConverter', 'White', 'Word', 'WordEnd', 'WordStart', 'ZeroOrMore', 'alphanums', 'alphas', 'alphas8bit', 'anyCloseTag', 'anyOpenTag', 'cStyleComment', 'col', 'commaSeparatedList', 'commonHTMLEntity', 'countedArray', 'cppStyleComment', 'dblQuotedString', 'dblSlashComment', 'delimitedList', 'dictOf', 'downcaseTokens', 'empty', 'hexnums', 'htmlComment', 'javaStyleComment', 'line', 'lineEnd', 'lineStart', 'lineno', 'makeHTMLTags', 'makeXMLTags', 'matchOnlyAtCol', 'matchPreviousExpr', 'matchPreviousLiteral', 'nestedExpr', 'nullDebugAction', 'nums', 'oneOf', 'opAssoc', 'operatorPrecedence', 'printables', 'punc8bit', 'pythonStyleComment', 'quotedString', 'removeQuotes', 'replaceHTMLEntity', 'replaceWith', 'restOfLine', 'sglQuotedString', 'srange', 'stringEnd', 'stringStart', 'traceParseAction', 'unicodeString', 'upcaseTokens', 'withAttribute', 'indentedBlock', 'originalTextFor', 'ungroup', 'infixNotation','locatedExpr', 'withClass', 'CloseMatch', 'tokenMap', 'pyparsing_common', ] system_version = tuple(sys.version_info)[:3] PY_3 = system_version[0] == 3 if PY_3: _MAX_INT = sys.maxsize basestring = str unichr = chr _ustr = str # build list of single arg builtins, that can be used as parse actions singleArgBuiltins = [sum, len, sorted, reversed, list, tuple, set, any, all, min, max] else: _MAX_INT = sys.maxint range = xrange def _ustr(obj): """Drop-in replacement for str(obj) that tries to be Unicode friendly.

To match an exact literal string, use L{Literal} or L{Keyword}. pyparsing includes helper strings for building Words: - L{alphas} - L{nums} - L{alphanums} - L{hexnums} - L{alphas8bit} (alphabetic characters in ASCII range 128-255 - accented, tilded, umlauted, etc.) - L{punc8bit} (non-alphabetic characters in ASCII range 128-255 - currency, symbols, superscripts, diacriticals, etc.) - L{printables} (any non-whitespace character) Example:: # a word composed of digits integer = Word(nums) # equivalent to Word("0123456789") or Word(srange("0-9")) # a word with a leading capital, and zero or more lowercase capital_word = Word(alphas.upper(), alphas.lower()) # hostnames are alphanumeric, with leading alpha, and '-' hostname = Word(alphas, alphanums+'-') # roman numeral (not a strict parser, accepts invalid mix of characters) roman = Word("IVXLCDM") # any string of non-whitespace characters, except for ',' csv_value = Word(printables, excludeChars=",") """ def __init__( self, initChars, bodyChars=None, min=1, max=0, exact=0, asKeyword=False, excludeChars=None ): super(Word,self).__init__() if excludeChars: initChars = ''.join(c for c in initChars if c not in excludeChars) if bodyChars: bodyChars = ''.join(c for c in bodyChars if c not in excludeChars) self.initCharsOrig = initChars self.initChars = set(initChars) if bodyChars : self.bodyCharsOrig = bodyChars self.bodyChars = set(bodyChars) else: self.bodyCharsOrig = initChars self.bodyChars = set(initChars) self.maxSpecified = max > 0 if min < 1: raise ValueError("cannot specify a minimum length < 1; use Optional(Word()) if zero-length word is permitted") self.minLen = min if max > 0: self.maxLen = max else: self.maxLen = _MAX_INT if exact > 0: self.maxLen = exact self.minLen = exact self.name = _ustr(self) self.errmsg = "Expected " + self.name self.mayIndexError = False self.asKeyword = asKeyword if ' ' not in self.initCharsOrig+self.bodyCharsOrig and (min==1 and max==0 and exact==0): if self.bodyCharsOrig == self.initCharsOrig: self.reString = "[%s]+" % _escapeRegexRangeChars(self.initCharsOrig) elif len(self.initCharsOrig) == 1: self.reString = "%s[%s]*" % \ (re.escape(self.initCharsOrig), _escapeRegexRangeChars(self.bodyCharsOrig),) else: self.reString = "[%s][%s]*" % \ (_escapeRegexRangeChars(self.initCharsOrig), _escapeRegexRangeChars(self.bodyCharsOrig),) if self.asKeyword: self.reString = r"\b"+self.reString+r"\b" try: self.re = re.compile( self.reString ) except Exception: self.re = None def parseImpl( self, instring, loc, doActions=True ): if self.re: result = self.re.match(instring,loc) if not result: raise ParseException(instring, loc, self.errmsg, self) loc = result.end() return loc, result.group() if not(instring[ loc ] in self.initChars): raise ParseException(instring, loc, self.errmsg, self) start = loc loc += 1 instrlen = len(instring) bodychars = self.bodyChars maxloc = start + self.maxLen maxloc = min( maxloc, instrlen ) while loc < maxloc and instring[loc] in bodychars: loc += 1 throwException = False if loc - start < self.minLen: throwException = True if self.maxSpecified and loc < instrlen and instring[loc] in bodychars: throwException = True if self.asKeyword: if (start>0 and instring[start-1] in bodychars) or (loc<instrlen and instring[loc] in bodychars): throwException = True if throwException: raise ParseException(instring, loc, self.errmsg, self) return loc, instring[start:loc] def __str__( self ): try: return super(Word,self).__str__() except Exception: pass if self.strRepr is None: def charsAsStr(s): if len(s)>4: return s[:4]+"..." else: return s if ( self.initCharsOrig != self.bodyCharsOrig ): self.strRepr = "W:(%s,%s)" % ( charsAsStr(self.initCharsOrig), charsAsStr(self.bodyCharsOrig) ) else: self.strRepr = "W:(%s)" % charsAsStr(self.initCharsOrig) return self.strRepr class Regex(Token): """ Token for matching strings that match a given regular expression.

With pyparsing, you don't need to learn a new syntax for defining grammars or matching expressions - the parsing module provides a library of classes that you use to construct the grammar directly in Python. Here is a program to parse "Hello, World!" (or any greeting of the form C{"<salutation>, <addressee>!"}), built up using L{Word}, L{Literal}, and L{And} elements (L{'+'<ParserElement.__add__>} operator gives L{And} expressions, strings are auto-converted to L{Literal} expressions):: from pyparsing import Word, alphas # define grammar of a greeting greet = Word(alphas) + "," + Word(alphas) + "!" hello = "Hello, World!" print (hello, "->", greet.parseString(hello)) The program outputs the following:: Hello, World! -> ['Hello', ',', 'World', '!'] The Python representation of the grammar is quite readable, owing to the self-explanatory class names, and the use of '+', '|' and '^' operators. The L{ParseResults} object returned from L{ParserElement.parseString<ParserElement.parseString>} can be accessed as a nested list, a dictionary, or an object with named attributes. The pyparsing module handles some of the problems that are typically vexing when writing text parsers: - extra or missing whitespace (the above program will also handle "Hello,World!", "Hello , World !", etc.) - quoted strings - embedded comments z2.1.10z07 Oct 2016 01:31 UTCz*Paul McGuire <ptmcg@users.sourceforge.net>� N)�ref)�datetime)�RLock)� OrderedDict�And�CaselessKeyword�CaselessLiteral� CharsNotIn�Combine�Dict�Each�Empty� FollowedBy�Forward� GoToColumn�Group�Keyword�LineEnd� LineStart�Literal� MatchFirst�NoMatch�NotAny� OneOrMore�OnlyOnce�Optional�Or�ParseBaseException�ParseElementEnhance�ParseException�ParseExpression�ParseFatalException� ParseResults�ParseSyntaxException� ParserElement� QuotedString�RecursiveGrammarException�Regex�SkipTo� StringEnd� StringStart�Suppress�Token�TokenConverter�White�Word�WordEnd� WordStart� ZeroOrMore� alphanums�alphas� alphas8bit� anyCloseTag� anyOpenTag� cStyleComment�col�commaSeparatedList�commonHTMLEntity� countedArray�cppStyleComment�dblQuotedString�dblSlashComment� delimitedList�dictOf�downcaseTokens�empty�hexnums� htmlComment�javaStyleComment�line�lineEnd� lineStart�lineno� makeHTMLTags� makeXMLTags�matchOnlyAtCol�matchPreviousExpr�matchPreviousLiteral� nestedExpr�nullDebugAction�nums�oneOf�opAssoc�operatorPrecedence� printables�punc8bit�pythonStyleComment� quotedString� removeQuotes�replaceHTMLEntity� replaceWith� restOfLine�sglQuotedString�srange� stringEnd� stringStart�traceParseAction� unicodeString� upcaseTokens� withAttribute� indentedBlock�originalTextFor�ungroup� infixNotation� locatedExpr� withClass� CloseMatch�tokenMap�pyparsing_common� c C s` t | t�r| S yt| �S tk rZ t| �jtj� d�}td�}|jdd� � |j |�S X dS )a Drop-in replacement for str(obj) that tries to be Unicode friendly.

Parse action fn is a callable method with 0-3 arguments, called as C{fn(s,loc,toks)}, C{fn(loc,toks)}, C{fn(toks)}, or just C{fn()}, where: - s = the original string being parsed (see note below) - loc = the location of the matching substring - toks = a list of the matched tokens, packaged as a C{L{ParseResults}} object If the functions in fns modify the tokens, they can return them as the return value from fn, and the modified list of tokens will replace the original. Otherwise, fn does not need to return any value. Optional keyword arguments: - callDuringTry = (default=C{False}) indicate if parse action should be run during lookaheads and alternate testing Note: the default parsing behavior is to expand tabs in the input string before starting the parsing process. See L{I{parseString}<parseString>} for more information on parsing strings containing C{<TAB>}s, and suggested methods to maintain a consistent view of the parsed string, the parse location, and line and column positions within the parsed string.

Repeated parse attempts at the same string location (which happens often in many complex grammars) can immediately return a cached value, instead of re-executing parsing/validating code. Memoizing is done of both valid results and parsing exceptions. Parameters: - cache_size_limit - (default=C{128}) - if an integer value is provided will limit the size of the packrat cache; if None is passed, then the cache size will be unbounded; if 0 is passed, the cache will be effectively disabled. This speedup may break existing programs that use parse actions that have side-effects. For this reason, packrat parsing is disabled when you first import pyparsing. To activate the packrat feature, your program must call the class method C{ParserElement.enablePackrat()}. If your program uses C{psyco} to "compile as you go", you must call C{enablePackrat} before calling C{psyco.full()}. If you do not do this, Python will crash. For best results, call C{enablePackrat()} immediately after importing pyparsing. Example:: import pyparsing pyparsing.ParserElement.enablePackrat() TN)r$ �_packratEnabledr� r� r� r� rt )Zcache_size_limitrw rw rx � enablePackrat s zParserElement.enablePackratc C s� t j� | js| j� x| jD ] }|j� q W | js<|j� }y<| j|d�\}}|rv| j||�}t � t � }|j||� W n0 t k r� } zt j r�� n|�W Y dd}~X nX |S dS )aB Execute the parse expression with the given string. This is the main interface to the client code, once the complete expression has been built. If you want the grammar to require that the entire input string be successfully parsed, then set C{parseAll} to True (equivalent to ending the grammar with C{L{StringEnd()}}). Note: C{parseString} implicitly calls C{expandtabs()} on the input string, in order to report proper column numbers in parse actions. If the input string contains tabs and the grammar uses parse actions that use the C{loc} argument to index into the string being parsed, you can ensure you have a consistent view of the input string by: - calling C{parseWithTabs} on your grammar before calling C{parseString} (see L{I{parseWithTabs}<parseWithTabs>}) - define your parse action using the full C{(s,loc,toks)} signature, and reference the input string using the parse action's C{s} argument - explictly expand the tabs in your input string before calling C{parseString} Example:: Word('a').parseString('aaaaabaaa') # -> ['aaaaa'] Word('a').parseString('aaaaabaaa', parseAll=True) # -> Exception: Expected end of text r N) r$ r� r_ � streamliner] r\ � expandtabsrt r� r r) r �verbose_stacktrace)r� r- �parseAllr� r� r� Zser3 rw rw rx � parseString# s$ zParserElement.parseStringc c s@ | j s| j� x| jD ] }|j� qW | js8t|�j� }t|�}d}| j}| j}t j � d} y�x�||kon| |k �ry |||�} ||| dd�\} } W n t k r� | d }Y q`X | |kr�| d7 } | | | fV |r�|||�} | |kr�| }q�|d7 }n| }q`| d }q`W W n4 t k �r: } zt j �r&� n|�W Y dd}~X nX dS )a� Scan the input string for expression matches. Each match will return the matching tokens, start location, and end location. May be called with optional C{maxMatches} argument, to clip scanning after 'n' matches are found. If C{overlap} is specified, then overlapping matches will be reported. Note that the start and end locations are reported relative to the string being parsed. See L{I{parseString}<parseString>} for more information on parsing strings with embedded tabs. Example:: source = "sldjf123lsdjjkf345sldkjf879lkjsfd987" print(source) for tokens,start,end in Word(alphas).scanString(source): print(' '*start + '^'*(end-start)) print(' '*start + tokens[0]) prints:: sldjf123lsdjjkf345sldkjf879lkjsfd987 ^^^^^ sldjf ^^^^^^^ lsdjjkf ^^^^^^ sldkjf ^^^^^^ lkjsfd r F)rp rr N)r_ r� r] r\ r� r� r� r� rt r$ r� r r r� )r� r- � maxMatchesZoverlapr� r� r� Z preparseFnZparseFn�matchesr� ZnextLocr� Znextlocr3 rw rw rx � scanStringU sB zParserElement.scanStringc C s� g }d}d| _ y�xh| j|�D ]Z\}}}|j|||� � |rrt|t�rT||j� 7 }n t|t�rh||7 }n |j|� |}q W |j||d� � dd� |D �}djtt t |���S t k r� } zt j rȂ n|�W Y dd}~X nX dS )af Extension to C{L{scanString}}, to modify matching text with modified tokens that may be returned from a parse action. To use C{transformString}, define a grammar and attach a parse action to it that modifies the returned token list. Invoking C{transformString()} on a target string will then scan for matches, and replace the matched text patterns according to the logic in the parse action. C{transformString()} returns the resulting transformed string. Example:: wd = Word(alphas) wd.setParseAction(lambda toks: toks[0].title()) print(wd.transformString("now is the winter of our discontent made glorious summer by this sun of york.")) Prints:: Now Is The Winter Of Our Discontent Made Glorious Summer By This Sun Of York. r TNc S s g | ] }|r|�qS rw rw )r� �orw rw rx r� � s z1ParserElement.transformString.<locals>.<listcomp>r� )r\ r� r� rz r" r� r� r� rv r� �_flattenr r$ r� )r� r- r ZlastErv r� r� r3 rw rw rx r� � s( z ParserElement.transformStringc C sP yt dd� | j||�D ��S tk rJ } ztjr6� n|�W Y dd}~X nX dS )a~ Another extension to C{L{scanString}}, simplifying the access to the tokens found to match the given parse expression.

C{CloseMatch} takes parameters: - C{match_string} - string to be matched - C{maxMismatches} - (C{default=1}) maximum number of mismatches allowed to count as a match The results from a successful parse will contain the matched text from the input string and the following named results: - C{mismatches} - a list of the positions within the match_string where mismatches were found - C{original} - the original match_string used to compare against the input string If C{mismatches} is an empty list, then the match was an exact match. Example:: patt = CloseMatch("ATCATCGAATGGA") patt.parseString("ATCATCGAAXGGA") # -> (['ATCATCGAAXGGA'], {'mismatches': [[9]], 'original': ['ATCATCGAATGGA']}) patt.parseString("ATCAXCGAAXGGA") # -> Exception: Expected 'ATCATCGAATGGA' (with up to 1 mismatches) (at char 0), (line:1, col:1) # exact match patt.parseString("ATCATCGAATGGA") # -> (['ATCATCGAATGGA'], {'mismatches': [[]], 'original': ['ATCATCGAATGGA']}) # close match allowing up to 2 mismatches patt = CloseMatch("ATCATCGAATGGA", maxMismatches=2) patt.parseString("ATCAXCGAAXGGA") # -> (['ATCAXCGAAXGGA'], {'mismatches': [[4, 9]], 'original': ['ATCATCGAATGGA']}) rr c sB t t| �j� || _|| _|| _d| j| jf | _d| _d| _d S )Nz&Expected %r (with up to %d mismatches)F) r� rl r� r� � match_string� maxMismatchesra r` r[ )r� r� r� )rH rw rx r� � s zCloseMatch.__init__Tc C s� |}t |�}|t | j� }||kr�| j}d}g } | j} x�tt|||� | j��D ]0\}} | \} } | | krP| j|� t | �| krPP qPW |d }t|||� g�}| j|d< | |d< ||fS t||| j| ��d S )Nr rr Zoriginal� mismatches) r� r� r� r� r� r� r" r ra )r� r- r� ro �startr� �maxlocr� Zmatch_stringlocr� r� Zs_m�src�mat�resultsrw rw rx r� � s( " zCloseMatch.parseImpl)rr )T)r� r� r� r� r� r� r� rw rw )rH rx rl � s c s8 e Zd ZdZd � fdd� Zdd d �Z� fd d �Z� ZS )r/ a Token for matching words composed of allowed character sets. Defined with string containing all allowed initial characters, an optional string containing allowed body characters (if omitted, defaults to the initial character set), and an optional minimum, maximum, and/or exact length. The default value for C{min} is 1 (a minimum value < 1 is not valid); the default values for C{max} and C{exact} are 0, meaning no maximum or exact length restriction. An optional C{excludeChars} parameter can list characters that might be found in the input C{bodyChars} string; useful to define a word of all printables except for one or two characters, for instance. L{srange} is useful for defining custom character set strings for defining C{Word} expressions, using range notation from regular expression character sets. A common mistake is to use C{Word} to match a specific literal string, as in C{Word("Address")}. Remember that C{Word} uses the string argument to define I{sets} of matchable characters. This expression would match "Add", "AAA", "dAred", or any other word made up of the characters 'A', 'd', 'r', 'e', and 's'. To match an exact literal string, use L{Literal} or L{Keyword}. pyparsing includes helper strings for building Words: - L{alphas} - L{nums} - L{alphanums} - L{hexnums} - L{alphas8bit} (alphabetic characters in ASCII range 128-255 - accented, tilded, umlauted, etc.) - L{punc8bit} (non-alphabetic characters in ASCII range 128-255 - currency, symbols, superscripts, diacriticals, etc.) - L{printables} (any non-whitespace character) Example:: # a word composed of digits integer = Word(nums) # equivalent to Word("0123456789") or Word(srange("0-9")) # a word with a leading capital, and zero or more lowercase capital_word = Word(alphas.upper(), alphas.lower()) # hostnames are alphanumeric, with leading alpha, and '-' hostname = Word(alphas, alphanums+'-') # roman numeral (not a strict parser, accepts invalid mix of characters) roman = Word("IVXLCDM") # any string of non-whitespace characters, except for ',' csv_value = Word(printables, excludeChars=",") Nrr r Fc s� t t| �j� � rFdj� fdd�|D ��}|rFdj� fdd�|D ��}|| _t|�| _|rl|| _t|�| _n|| _t|�| _|dk| _ |dk r�t d��|| _ |dkr�|| _ nt | _ |dkr�|| _ || _ t| �| _d| j | _d | _|| _d | j| j k�r�|dk�r�|dk�r�|dk�r�| j| jk�r8d t| j� | _nHt| j�dk�rfd tj| j�t| j�f | _nd t| j�t| j�f | _| j�r�d| j d | _ytj| j�| _W n tk �r� d | _Y nX d S )Nr� c 3 s | ]}|� kr|V qd S )Nrw )r� r� )� excludeCharsrw rx r� 7 s z Word.__init__.<locals>.<genexpr>c 3 s | ]}|� kr|V qd S )Nrw )r� r� )r� rw rx r� 9 s r rr zZcannot specify a minimum length < 1; use Optional(Word()) if zero-length word is permittedz Expected Fr� z[%s]+z%s[%s]*z [%s][%s]*z\b)r� r/ r� r� � initCharsOrigr� � initChars� bodyCharsOrig� bodyChars� maxSpecifiedr� �minLen�maxLenr� r� r� ra r` � asKeyword�_escapeRegexRangeChars�reStringr� rd �escape�compilerK )r� r� r �min�max�exactr r� )rH )r� rx r� 4 sT 0 z Word.__init__Tc C sD | j r<| j j||�}|s(t||| j| ��|j� }||j� fS || | jkrZt||| j| ��|}|d7 }t|�}| j}|| j }t ||�}x ||k r�|| |kr�|d7 }q�W d} || | j k r�d} | j r�||k r�|| |kr�d} | j �r |dk�r||d |k�s||k �r || |k�r d} | �r4t||| j| ��||||� fS )Nrr FTr )rd r� r ra �end�groupr� r� r r r r r r ) r� r- r� ro r� r� r� Z bodycharsr� ZthrowExceptionrw rw rx r� j s6 4zWord.parseImplc st yt t| �j� S tk r" Y nX | jd krndd� }| j| jkr^d|| j�|| j�f | _nd|| j� | _| jS )Nc S s$ t | �dkr | d d� d S | S d S )N� z...)r� )r� rw rw rx � charsAsStr� s z Word.__str__.<locals>.charsAsStrz W:(%s,%s)zW:(%s))r� r/ r� rK rU r� r )r� r )rH rw rx r� � s z Word.__str__)Nrr r r FN)T)r� r� r� r� r� r� r� r� rw rw )rH rx r/ s .6 #c sF e Zd ZdZeejd��Zd � fdd� Zd dd�Z � fd d �Z � Z S ) r' a� Token for matching strings that match a given regular expression.

When the expression is known, it is assigned to the C{Forward} variable using the '<<' operator. Note: take care when assigning to C{Forward} not to overlook precedence of operators. Specifically, '|' has a lower precedence than '<<', so that:: fwdExpr << a | b | c will actually be evaluated as:: (fwdExpr << a) | b | c thereby leaving b and c out as parseable alternatives. It is recommended that you explicitly group the values inserted into the C{Forward}:: fwdExpr << (a | b | c) Converting to use the '<<=' operator instead will avoid this problem.

By default, the list elements and delimiters can have intervening whitespace, and comments, but this can be overridden by passing C{combine=True} in the constructor. If C{combine} is set to C{True}, the matching tokens are returned as a single token string, with the delimiters included; otherwise, the matching tokens are returned as a list of tokens, with the delimiters suppressed. Example:: delimitedList(Word(alphas)).parseString("aa,bb,cc") # -> ['aa', 'bb', 'cc'] delimitedList(Word(hexnums), delim=':', combine=True).parseString("AA:BB:CC:DD:EE") # -> ['AA:BB:CC:DD:EE'] z [r� z]...N)r� r r2 ri r+ )r.

This helper defines a pattern of the form:: integer expr expr expr... where the leading integer tells how many expr expressions follow. The matched tokens returns the array of expr tokens as a list - the leading count token is suppressed. If C{intExpr} is specified, it should be a pyparsing expression that produces an integer value. Example:: countedArray(Word(alphas)).parseString('2 ab cd ef') # -> ['ab', 'cd'] # in this parser, the leading integer value is given in binary, # '10' indicating that 2 values are in the array binaryConstant = Word('01').setParseAction(lambda t: int(t[0], 2)) countedArray(Word(alphas), intExpr=binaryConstant).parseString('10 ab cd ef') # -> ['ab', 'cd'] c s. |d }� |r t t�g| ��p&t t�> g S )Nr )r r rC )r� r5 rv r� )� arrayExprr. rw rx �countFieldParseAction_ s "z+countedArray.<locals>.countFieldParseActionNc S s t | d �S )Nr )ru )rv rw rw rx ry d s z countedArray.<locals>.<lambda>ZarrayLenT)rf z(len) z...)r r/ rR r� r� ri rx r� )r.

Parameters: - strs - a string of space-delimited literals, or a collection of string literals - caseless - (default=C{False}) - treat all literals as caseless - useRegex - (default=C{True}) - as an optimization, will generate a Regex object; otherwise, will generate a C{MatchFirst} object (if C{caseless=True}, or if creating a C{Regex} raises an exception) Example:: comp_oper = oneOf("< = > <= >= !=") var = Word(alphas) number = Word(nums) term = var | number comparison_expr = term + comp_oper + term print(comparison_expr.searchString("B = 12 AA=23 B<=AA AA>12")) prints:: [['B', '=', '12'], ['AA', '=', '23'], ['B', '<=', 'AA'], ['AA', '>', '12']] c S s | j � |j � kS )N)r� )r �brw rw rx ry � s zoneOf.<locals>.<lambda>c S s |j � j| j � �S )N)r� r� )r rk rw rw rx ry � s c S s | |kS )Nrw )r rk rw rw rx ry � s c S s |j | �S )N)r� )r rk rw rw rx ry � s z6Invalid argument to oneOf, expected string or iterablerq )r� r rr Nr� z[%s]c s s | ]}t |�V qd S )N)r )r� �symrw rw rx r� � s zoneOf.<locals>.<genexpr>z | �|c s s | ]}t j|�V qd S )N)rd r )r� rl rw rw rx r� � s z7Exception creating Regex for oneOf, building MatchFirstc 3 s | ]}� |�V qd S )Nrw )r� rl )�parseElementClassrw rx r� � s )r r rz r� r� r� r4 r� r� r� r� r r� r� r� r� r' ri rK r ) Zstrsr� ZuseRegexZisequalZmasksZsymbolsr� Zcurr� r� rw )rn rx rS � sL ((c C s t tt| | ���S )a� Helper to easily and clearly define a dictionary by specifying the respective patterns for the key and value. Takes care of defining the C{L{Dict}}, C{L{ZeroOrMore}}, and C{L{Group}} tokens in the proper order. The key pattern can include delimiting markers or punctuation, as long as they are suppressed, thereby leaving the significant key text. The value pattern can include named results, so that the C{Dict} results can include named token fields. Example:: text = "shape: SQUARE posn: upper left color: light blue texture: burlap" attr_expr = (label + Suppress(':') + OneOrMore(data_word, stopOn=label).setParseAction(' '.join)) print(OneOrMore(attr_expr).parseString(text).dump()) attr_label = label attr_value = Suppress(':') + OneOrMore(data_word, stopOn=label).setParseAction(' '.join) # similar to Dict, but simpler call format result = dictOf(attr_label, attr_value).parseString(text) print(result.dump()) print(result['shape']) print(result.shape) # object attribute access works too print(result.asDict()) prints:: [['shape', 'SQUARE'], ['posn', 'upper left'], ['color', 'light blue'], ['texture', 'burlap']] - color: light blue - posn: upper left - shape: SQUARE - texture: burlap SQUARE SQUARE {'color': 'light blue', 'shape': 'SQUARE', 'posn': 'upper left', 'texture': 'burlap'} )r r2 r )r� r� rw rw rx rA � s !c C s^ t � jdd� �}|j� }d|_|d�| |d� }|r@dd� }ndd� }|j|� | j|_|S ) a� Helper to return the original, untokenized text for a given expression. Useful to restore the parsed fields of an HTML start tag into the raw tag text itself, or to revert separate tokens with intervening whitespace back to the original matching input text. By default, returns astring containing the original parsed text. If the optional C{asString} argument is passed as C{False}, then the return value is a C{L{ParseResults}} containing any results names that were originally matched, and a single token containing the original matched text from the input string. So if the expression passed to C{L{originalTextFor}} contains expressions with defined results names, you must set C{asString} to C{False} if you want to preserve those results name values. Example:: src = "this is test <b> bold <i>text</i> </b> normal text " for tag in ("b","i"): opener,closer = makeHTMLTags(tag) patt = originalTextFor(opener + SkipTo(closer) + closer) print(patt.searchString(src)[0]) prints:: ['<b> bold <i>text</i> </b>'] ['<i>text</i>'] c S s |S )Nrw )r� r� rv rw rw rx ry 8 s z!originalTextFor.<locals>.<lambda>F�_original_start� _original_endc S s | |j |j� S )N)ro rp )r� r5 rv rw rw rx ry = s c S s& | |j d�|j d�� g|d d �< d S )Nro rp )r� )r� r5 rv rw rw rx � extractText? s z$originalTextFor.<locals>.extractText)r r� r� re r] )r.

Borrows syntax from regexp '[]' string range definitions:: srange("[0-9]") -> "0123456789" srange("[a-z]") -> "abcdefghijklmnopqrstuvwxyz" srange("[a-z$_]") -> "abcdefghijklmnopqrstuvwxyz$_" The input string must be enclosed in []'s, and the returned string is the expanded character set joined into a single string. The values enclosed in the []'s may be: - a single character - an escaped character with a leading backslash (such as C{\-} or C{\]}) - an escaped hex character with a leading C{'\x'} (C{\x21}, which is a C{'!'} character) (C{\0x##} is also supported for backwards compatibility) - an escaped octal character with a leading C{'\0'} (C{\041}, which is a C{'!'} character) - a range of any of the above, separated by a dash (C{'a-z'}, etc.) - any combination of the above (C{'aeiouy'}, C{'a-zA-Z0-9_$'}, etc.) c S s< t | t�s| S djdd� tt| d �t| d �d �D ��S )Nr� c s s | ]}t |�V qd S )N)rt )r� r� rw rw rx r� � s z+srange.<locals>.<lambda>.<locals>.<genexpr>r rr )rz r" r� r� �ord)�prw rw rx ry � s zsrange.<locals>.<lambda>r� c 3 s | ]}� |�V qd S )Nrw )r� �part)� _expandedrw rx r� � s zsrange.<locals>.<genexpr>N)r� �_reBracketExprr� rw rK )r� rw )r{ rx r_ r s c s � fdd�}|S )zt Helper method for defining parse actions that require matching at a specific column in the input text. c s" t || �� kr t| |d� ��d S )Nz matched token not at column %d)r9 r )r) Zlocnr1 )r� rw rx � verifyCol� s z!matchOnlyAtCol.<locals>.verifyColrw )r� r} rw )r� rx rM � s c s � fdd�S )a� Helper method for common parse actions that simply return a literal value.

Use C{withAttribute} to qualify a starting tag with a required attribute value, to avoid false matches on common tags such as C{<TD>} or C{<DIV>}. Call C{withAttribute} with a series of attribute names and values. Specify the list of filter attributes names and values as: - keyword arguments, as in C{(align="right")}, or - as an explicit dict with C{**} operator, when an attribute name is also a Python reserved word, as in C{**{"class":"Customer", "align":"right"}} - a list of name-value tuples, as in ( ("ns1:class", "Customer"), ("ns2:align","right") ) For attribute names with a namespace prefix, you must use the second form. Attribute names are matched insensitive to upper/lower case. If just testing for C{class} (with or without a namespace), use C{L{withClass}}. To verify that the attribute exists, but without specifying a value, pass C{withAttribute.ANY_VALUE} as the value. Example:: html = ''' <div> Some text <div type="grid">1 4 0 1 0</div> <div type="graph">1,3 2,3 1,1</div> <div>this has no type</div> </div> ''' div,div_end = makeHTMLTags("div") # only match div tag having a type attribute with value "grid" div_grid = div().setParseAction(withAttribute(type="grid")) grid_expr = div_grid + SkipTo(div | div_end)("body") for grid_header in grid_expr.searchString(html): print(grid_header.body) # construct a match with any div tag having a type attribute, regardless of the value div_any_type = div().setParseAction(withAttribute(type=withAttribute.ANY_VALUE)) div_expr = div_any_type + SkipTo(div | div_end)("body") for div_header in div_expr.searchString(html): print(div_header.body) prints:: 1 4 0 1 0 1 4 0 1 0 1,3 2,3 1,1 Nc S s g | ]\}}||f�qS rw rw )r� r� r� rw rw rx r� Q s z!withAttribute.<locals>.<listcomp>c s^ xX� D ]P\}}||kr&t | |d| ��|tjkr|| |krt | |d||| |f ��qW d S )Nzno matching attribute z+attribute '%s' has value '%s', must be '%s')r re � ANY_VALUE)r� r5 r� ZattrNameZ attrValue)�attrsrw rx r} R s zwithAttribute.<locals>.pa)r� )r� ZattrDictr} rw )r� rx re s 2 c C s |r d| nd}t f || i�S )a� Simplified version of C{L{withAttribute}} when matching on a div class - made difficult because C{class} is a reserved word in Python.

Operators may be unary or binary, left- or right-associative. Parse actions can also be attached to operator expressions. The generated parser will also recognize the use of parentheses to override operator precedences (see example below). Note: if you define a deep operator list, you may see performance issues when using infixNotation. See L{ParserElement.enablePackrat} for a mechanism to potentially improve your parser performance. Parameters: - baseExpr - expression representing the most basic element for the nested - opList - list of tuples, one for each operator precedence level in the expression grammar; each tuple is of the form (opExpr, numTerms, rightLeftAssoc, parseAction), where: - opExpr is the pyparsing expression for the operator; may also be a string, which will be converted to a Literal; if numTerms is 3, opExpr is a tuple of two expressions, for the two operators separating the 3 terms - numTerms is the number of terms for this operator (must be 1, 2, or 3) - rightLeftAssoc is the indicator whether the operator is right or left associative, using the pyparsing-defined constants C{opAssoc.RIGHT} and C{opAssoc.LEFT}. - parseAction is the parse action to be associated with expressions matching this operator expression (the parse action tuple member may be omitted) - lpar - expression for matching left-parentheses (default=C{Suppress('(')}) - rpar - expression for matching right-parentheses (default=C{Suppress(')')}) Example:: # simple example of four-function arithmetic with ints and variable names integer = pyparsing_common.signed_integer varname = pyparsing_common.identifier arith_expr = infixNotation(integer | varname, [ ('-', 1, opAssoc.RIGHT), (oneOf('* /'), 2, opAssoc.LEFT), (oneOf('+ -'), 2, opAssoc.LEFT), ]) arith_expr.runTests(''' 5+3*6 (5+3)*6 -2--11 ''', fullDump=False) prints:: 5+3*6 [[5, '+', [3, '*', 6]]] (5+3)*6 [[[5, '+', 3], '*', 6]] -2--11 [[['-', 2], '-', ['-', 11]]] Nr ro z%s termz %s%s termrq z@if numterms=3, opExpr must be a tuple or list of two expressionsrr z6operator must be unary (1), binary (2), or ternary (3)z2operator must indicate right or left associativity)N)r r� r� r� ri rT �LEFTr r r �RIGHTrz r r. r� )ZbaseExprZopListZlparZrparr� ZlastExprr� ZoperDefZopExprZarityZrightLeftAssocr} ZtermNameZopExpr1ZopExpr2ZthisExprrr rw rw rx ri � sR ; & & z4"(?:[^"\n\r\\]|(?:"")|(?:\\(?:[^x]|x[0-9a-fA-F]+)))*�"z string enclosed in double quotesz4'(?:[^'\n\r\\]|(?:'')|(?:\\(?:[^x]|x[0-9a-fA-F]+)))*�'z string enclosed in single quotesz*quotedString using single or double quotes�uzunicode string literalc C s� | |krt d��|dk�r(t| t�o,t|t��r t| �dkr�t|�dkr�|dk r�tt| t| | tj dd� ��j dd� �}n$t j � t| | tj �j dd� � }nx|dk r�tt| t | � t |� ttjdd� ��j dd� �}n4ttt | � t |� ttjdd� ��j d d� �}nt d ��t � }|dk �rb|tt| �t||B |B � t|� �K }n$|tt| �t||B � t|� �K }|jd | |f � |S ) a~ Helper method for defining nested lists enclosed in opening and closing delimiters ("(" and ")" are the default). Parameters: - opener - opening character for a nested list (default=C{"("}); can also be a pyparsing expression - closer - closing character for a nested list (default=C{")"}); can also be a pyparsing expression - content - expression for items within the nested lists (default=C{None}) - ignoreExpr - expression for ignoring opening and closing delimiters (default=C{quotedString}) If an expression is not provided for the content argument, the nested expression will capture all whitespace-delimited content between delimiters as a list of separate values. Use the C{ignoreExpr} argument to define expressions that may contain opening or closing characters that should not be treated as opening or closing characters for nesting, such as quotedString or a comment expression. Specify multiple expressions using an C{L{Or}} or C{L{MatchFirst}}. The default is L{quotedString}, but if no expressions are to be ignored, then pass C{None} for this argument. Example:: data_type = oneOf("void int short long char float double") decl_data_type = Combine(data_type + Optional(Word('*'))) ident = Word(alphas+'_', alphanums+'_') number = pyparsing_common.number arg = Group(decl_data_type + ident) LPAR,RPAR = map(Suppress, "()") code_body = nestedExpr('{', '}', ignoreExpr=(quotedString | cStyleComment)) c_function = (decl_data_type("type") + ident("name") + LPAR + Optional(delimitedList(arg), [])("args") + RPAR + code_body("body")) c_function.ignore(cStyleComment) source_code = ''' int is_odd(int x) { return (x%2); } int dec_to_hex(char hchar) { if (hchar >= '0' && hchar <= '9') { return (ord(hchar)-ord('0')); } else { return (10+ord(hchar)-ord('A')); } } ''' for func in c_function.searchString(source_code): print("%(name)s (%(type)s) args: %(args)s" % func) prints:: is_odd (int) args: [['int', 'x']] dec_to_hex (int) args: [['char', 'hchar']] z.opening and closing strings cannot be the sameNrr )r c S s | d j � S )Nr )r� )rv rw rw rx ry 9 s z nestedExpr.<locals>.<lambda>c S s | d j � S )Nr )r� )rv rw rw rx ry < s c S s | d j � S )Nr )r� )rv rw rw rx ry B s c S s | d j � S )Nr )r� )rv rw rw rx ry F s zOopening and closing arguments must be strings if no content expression is givenznested %s%s expression)r� rz r� r� r r r r$ rN r� rC r� r r r r+ r2 ri )�openerZcloserZcontentrN r� rw rw rx rP � s4 : *$c s� � fdd�}� fdd�}� fdd�}t t� jd�j� �}t� t� j|� jd�}t� j|�jd �}t� j|�jd �} |r�tt|�| t |t| � t|� � | �} n$tt|�t |t| � t|� � �} | j t t� � | jd �S ) a Helper method for defining space-delimited indentation blocks, such as those used to define block statements in Python source code.

With pyparsing, you don't need to learn a new syntax for defining grammars or matching expressions - the parsing module provides a library of classes that you use to construct the grammar directly in Python. Here is a program to parse "Hello, World!" (or any greeting of the form C{"<salutation>, <addressee>!"}), built up using L{Word}, L{Literal}, and L{And} elements (L{'+'<ParserElement.__add__>} operator gives L{And} expressions, strings are auto-converted to L{Literal} expressions):: from pyparsing import Word, alphas # define grammar of a greeting greet = Word(alphas) + "," + Word(alphas) + "!" hello = "Hello, World!" print (hello, "->", greet.parseString(hello)) The program outputs the following:: Hello, World! -> ['Hello', ',', 'World', '!'] The Python representation of the grammar is quite readable, owing to the self-explanatory class names, and the use of '+', '|' and '^' operators. The L{ParseResults} object returned from L{ParserElement.parseString<ParserElement.parseString>} can be accessed as a nested list, a dictionary, or an object with named attributes. The pyparsing module handles some of the problems that are typically vexing when writing text parsers: - extra or missing whitespace (the above program will also handle "Hello,World!", "Hello , World !", etc.) - quoted strings - embedded comments z2.1.10z07 Oct 2016 01:31 UTCz*Paul McGuire <ptmcg@users.sourceforge.net>� N)�ref)�datetime)�RLock)� OrderedDict�And�CaselessKeyword�CaselessLiteral� CharsNotIn�Combine�Dict�Each�Empty� FollowedBy�Forward� GoToColumn�Group�Keyword�LineEnd� LineStart�Literal� MatchFirst�NoMatch�NotAny� OneOrMore�OnlyOnce�Optional�Or�ParseBaseException�ParseElementEnhance�ParseException�ParseExpression�ParseFatalException� ParseResults�ParseSyntaxException� ParserElement� QuotedString�RecursiveGrammarException�Regex�SkipTo� StringEnd� StringStart�Suppress�Token�TokenConverter�White�Word�WordEnd� WordStart� ZeroOrMore� alphanums�alphas� alphas8bit� anyCloseTag� anyOpenTag� cStyleComment�col�commaSeparatedList�commonHTMLEntity� countedArray�cppStyleComment�dblQuotedString�dblSlashComment� delimitedList�dictOf�downcaseTokens�empty�hexnums� htmlComment�javaStyleComment�line�lineEnd� lineStart�lineno� makeHTMLTags� makeXMLTags�matchOnlyAtCol�matchPreviousExpr�matchPreviousLiteral� nestedExpr�nullDebugAction�nums�oneOf�opAssoc�operatorPrecedence� printables�punc8bit�pythonStyleComment� quotedString� removeQuotes�replaceHTMLEntity� replaceWith� restOfLine�sglQuotedString�srange� stringEnd� stringStart�traceParseAction� unicodeString� upcaseTokens� withAttribute� indentedBlock�originalTextFor�ungroup� infixNotation� locatedExpr� withClass� CloseMatch�tokenMap�pyparsing_common� c C s` t | t�r| S yt| �S tk rZ t| �jtj� d�}td�}|jdd� � |j |�S X dS )a Drop-in replacement for str(obj) that tries to be Unicode friendly.

Parse action fn is a callable method with 0-3 arguments, called as C{fn(s,loc,toks)}, C{fn(loc,toks)}, C{fn(toks)}, or just C{fn()}, where: - s = the original string being parsed (see note below) - loc = the location of the matching substring - toks = a list of the matched tokens, packaged as a C{L{ParseResults}} object If the functions in fns modify the tokens, they can return them as the return value from fn, and the modified list of tokens will replace the original. Otherwise, fn does not need to return any value. Optional keyword arguments: - callDuringTry = (default=C{False}) indicate if parse action should be run during lookaheads and alternate testing Note: the default parsing behavior is to expand tabs in the input string before starting the parsing process. See L{I{parseString}<parseString>} for more information on parsing strings containing C{<TAB>}s, and suggested methods to maintain a consistent view of the parsed string, the parse location, and line and column positions within the parsed string.

Repeated parse attempts at the same string location (which happens often in many complex grammars) can immediately return a cached value, instead of re-executing parsing/validating code. Memoizing is done of both valid results and parsing exceptions. Parameters: - cache_size_limit - (default=C{128}) - if an integer value is provided will limit the size of the packrat cache; if None is passed, then the cache size will be unbounded; if 0 is passed, the cache will be effectively disabled. This speedup may break existing programs that use parse actions that have side-effects. For this reason, packrat parsing is disabled when you first import pyparsing. To activate the packrat feature, your program must call the class method C{ParserElement.enablePackrat()}. If your program uses C{psyco} to "compile as you go", you must call C{enablePackrat} before calling C{psyco.full()}. If you do not do this, Python will crash. For best results, call C{enablePackrat()} immediately after importing pyparsing. Example:: import pyparsing pyparsing.ParserElement.enablePackrat() TN)r$ �_packratEnabledr� r� r� r� rt )Zcache_size_limitrw rw rx � enablePackrat s zParserElement.enablePackratc C s� t j� | js| j� x| jD ] }|j� q W | js<|j� }y<| j|d�\}}|rv| j||�}t � t � }|j||� W n0 t k r� } zt j r�� n|�W Y dd}~X nX |S dS )aB Execute the parse expression with the given string. This is the main interface to the client code, once the complete expression has been built. If you want the grammar to require that the entire input string be successfully parsed, then set C{parseAll} to True (equivalent to ending the grammar with C{L{StringEnd()}}). Note: C{parseString} implicitly calls C{expandtabs()} on the input string, in order to report proper column numbers in parse actions. If the input string contains tabs and the grammar uses parse actions that use the C{loc} argument to index into the string being parsed, you can ensure you have a consistent view of the input string by: - calling C{parseWithTabs} on your grammar before calling C{parseString} (see L{I{parseWithTabs}<parseWithTabs>}) - define your parse action using the full C{(s,loc,toks)} signature, and reference the input string using the parse action's C{s} argument - explictly expand the tabs in your input string before calling C{parseString} Example:: Word('a').parseString('aaaaabaaa') # -> ['aaaaa'] Word('a').parseString('aaaaabaaa', parseAll=True) # -> Exception: Expected end of text r N) r$ r� r_ � streamliner] r\ � expandtabsrt r� r r) r �verbose_stacktrace)r� r- �parseAllr� r� r� Zser3 rw rw rx � parseString# s$ zParserElement.parseStringc c s@ | j s| j� x| jD ] }|j� qW | js8t|�j� }t|�}d}| j}| j}t j � d} y�x�||kon| |k �ry |||�} ||| dd�\} } W n t k r� | d }Y q`X | |kr�| d7 } | | | fV |r�|||�} | |kr�| }q�|d7 }n| }q`| d }q`W W n4 t k �r: } zt j �r&� n|�W Y dd}~X nX dS )a� Scan the input string for expression matches. Each match will return the matching tokens, start location, and end location. May be called with optional C{maxMatches} argument, to clip scanning after 'n' matches are found. If C{overlap} is specified, then overlapping matches will be reported. Note that the start and end locations are reported relative to the string being parsed. See L{I{parseString}<parseString>} for more information on parsing strings with embedded tabs. Example:: source = "sldjf123lsdjjkf345sldkjf879lkjsfd987" print(source) for tokens,start,end in Word(alphas).scanString(source): print(' '*start + '^'*(end-start)) print(' '*start + tokens[0]) prints:: sldjf123lsdjjkf345sldkjf879lkjsfd987 ^^^^^ sldjf ^^^^^^^ lsdjjkf ^^^^^^ sldkjf ^^^^^^ lkjsfd r F)rp rr N)r_ r� r] r\ r� r� r� r� rt r$ r� r r r� )r� r- � maxMatchesZoverlapr� r� r� Z preparseFnZparseFn�matchesr� ZnextLocr� Znextlocr3 rw rw rx � scanStringU sB zParserElement.scanStringc C s� g }d}d| _ y�xh| j|�D ]Z\}}}|j|||� � |rrt|t�rT||j� 7 }n t|t�rh||7 }n |j|� |}q W |j||d� � dd� |D �}djtt t |���S t k r� } zt j rȂ n|�W Y dd}~X nX dS )af Extension to C{L{scanString}}, to modify matching text with modified tokens that may be returned from a parse action. To use C{transformString}, define a grammar and attach a parse action to it that modifies the returned token list. Invoking C{transformString()} on a target string will then scan for matches, and replace the matched text patterns according to the logic in the parse action. C{transformString()} returns the resulting transformed string. Example:: wd = Word(alphas) wd.setParseAction(lambda toks: toks[0].title()) print(wd.transformString("now is the winter of our discontent made glorious summer by this sun of york.")) Prints:: Now Is The Winter Of Our Discontent Made Glorious Summer By This Sun Of York. r TNc S s g | ] }|r|�qS rw rw )r� �orw rw rx r� � s z1ParserElement.transformString.<locals>.<listcomp>r� )r\ r� r� rz r" r� r� r� rv r� �_flattenr r$ r� )r� r- r ZlastErv r� r� r3 rw rw rx r� � s( z ParserElement.transformStringc C sP yt dd� | j||�D ��S tk rJ } ztjr6� n|�W Y dd}~X nX dS )a~ Another extension to C{L{scanString}}, simplifying the access to the tokens found to match the given parse expression.

C{CloseMatch} takes parameters: - C{match_string} - string to be matched - C{maxMismatches} - (C{default=1}) maximum number of mismatches allowed to count as a match The results from a successful parse will contain the matched text from the input string and the following named results: - C{mismatches} - a list of the positions within the match_string where mismatches were found - C{original} - the original match_string used to compare against the input string If C{mismatches} is an empty list, then the match was an exact match. Example:: patt = CloseMatch("ATCATCGAATGGA") patt.parseString("ATCATCGAAXGGA") # -> (['ATCATCGAAXGGA'], {'mismatches': [[9]], 'original': ['ATCATCGAATGGA']}) patt.parseString("ATCAXCGAAXGGA") # -> Exception: Expected 'ATCATCGAATGGA' (with up to 1 mismatches) (at char 0), (line:1, col:1) # exact match patt.parseString("ATCATCGAATGGA") # -> (['ATCATCGAATGGA'], {'mismatches': [[]], 'original': ['ATCATCGAATGGA']}) # close match allowing up to 2 mismatches patt = CloseMatch("ATCATCGAATGGA", maxMismatches=2) patt.parseString("ATCAXCGAAXGGA") # -> (['ATCAXCGAAXGGA'], {'mismatches': [[4, 9]], 'original': ['ATCATCGAATGGA']}) rr c sB t t| �j� || _|| _|| _d| j| jf | _d| _d| _d S )Nz&Expected %r (with up to %d mismatches)F) r� rl r� r� � match_string� maxMismatchesra r` r[ )r� r� r� )rH rw rx r� � s zCloseMatch.__init__Tc C s� |}t |�}|t | j� }||kr�| j}d}g } | j} x�tt|||� | j��D ]0\}} | \} } | | krP| j|� t | �| krPP qPW |d }t|||� g�}| j|d< | |d< ||fS t||| j| ��d S )Nr rr Zoriginal� mismatches) r� r� r� r� r� r� r" r ra )r� r- r� ro �startr� �maxlocr� Zmatch_stringlocr� r� Zs_m�src�mat�resultsrw rw rx r� � s( " zCloseMatch.parseImpl)rr )T)r� r� r� r� r� r� r� rw rw )rH rx rl � s c s8 e Zd ZdZd � fdd� Zdd d �Z� fd d �Z� ZS )r/ a Token for matching words composed of allowed character sets. Defined with string containing all allowed initial characters, an optional string containing allowed body characters (if omitted, defaults to the initial character set), and an optional minimum, maximum, and/or exact length. The default value for C{min} is 1 (a minimum value < 1 is not valid); the default values for C{max} and C{exact} are 0, meaning no maximum or exact length restriction. An optional C{excludeChars} parameter can list characters that might be found in the input C{bodyChars} string; useful to define a word of all printables except for one or two characters, for instance. L{srange} is useful for defining custom character set strings for defining C{Word} expressions, using range notation from regular expression character sets. A common mistake is to use C{Word} to match a specific literal string, as in C{Word("Address")}. Remember that C{Word} uses the string argument to define I{sets} of matchable characters. This expression would match "Add", "AAA", "dAred", or any other word made up of the characters 'A', 'd', 'r', 'e', and 's'. To match an exact literal string, use L{Literal} or L{Keyword}. pyparsing includes helper strings for building Words: - L{alphas} - L{nums} - L{alphanums} - L{hexnums} - L{alphas8bit} (alphabetic characters in ASCII range 128-255 - accented, tilded, umlauted, etc.) - L{punc8bit} (non-alphabetic characters in ASCII range 128-255 - currency, symbols, superscripts, diacriticals, etc.) - L{printables} (any non-whitespace character) Example:: # a word composed of digits integer = Word(nums) # equivalent to Word("0123456789") or Word(srange("0-9")) # a word with a leading capital, and zero or more lowercase capital_word = Word(alphas.upper(), alphas.lower()) # hostnames are alphanumeric, with leading alpha, and '-' hostname = Word(alphas, alphanums+'-') # roman numeral (not a strict parser, accepts invalid mix of characters) roman = Word("IVXLCDM") # any string of non-whitespace characters, except for ',' csv_value = Word(printables, excludeChars=",") Nrr r Fc s� t t| �j� � rFdj� fdd�|D ��}|rFdj� fdd�|D ��}|| _t|�| _|rl|| _t|�| _n|| _t|�| _|dk| _ |dk r�t d��|| _ |dkr�|| _ nt | _ |dkr�|| _ || _ t| �| _d| j | _d | _|| _d | j| j k�r�|dk�r�|dk�r�|dk�r�| j| jk�r8d t| j� | _nHt| j�dk�rfd tj| j�t| j�f | _nd t| j�t| j�f | _| j�r�d| j d | _ytj| j�| _W n tk �r� d | _Y nX d S )Nr� c 3 s | ]}|� kr|V qd S )Nrw )r� r� )� excludeCharsrw rx r� 7 s z Word.__init__.<locals>.<genexpr>c 3 s | ]}|� kr|V qd S )Nrw )r� r� )r� rw rx r� 9 s r rr zZcannot specify a minimum length < 1; use Optional(Word()) if zero-length word is permittedz Expected Fr� z[%s]+z%s[%s]*z [%s][%s]*z\b)r� r/ r� r� � initCharsOrigr� � initChars� bodyCharsOrig� bodyChars� maxSpecifiedr� �minLen�maxLenr� r� r� ra r` � asKeyword�_escapeRegexRangeChars�reStringr� rd �escape�compilerK )r� r� r �min�max�exactr r� )rH )r� rx r� 4 sT 0 z Word.__init__Tc C sD | j r<| j j||�}|s(t||| j| ��|j� }||j� fS || | jkrZt||| j| ��|}|d7 }t|�}| j}|| j }t ||�}x ||k r�|| |kr�|d7 }q�W d} || | j k r�d} | j r�||k r�|| |kr�d} | j �r |dk�r||d |k�s||k �r || |k�r d} | �r4t||| j| ��||||� fS )Nrr FTr )rd r� r ra �end�groupr� r� r r r r r r ) r� r- r� ro r� r� r� Z bodycharsr� ZthrowExceptionrw rw rx r� j s6 4zWord.parseImplc st yt t| �j� S tk r" Y nX | jd krndd� }| j| jkr^d|| j�|| j�f | _nd|| j� | _| jS )Nc S s$ t | �dkr | d d� d S | S d S )N� z...)r� )r� rw rw rx � charsAsStr� s z Word.__str__.<locals>.charsAsStrz W:(%s,%s)zW:(%s))r� r/ r� rK rU r� r )r� r )rH rw rx r� � s z Word.__str__)Nrr r r FN)T)r� r� r� r� r� r� r� r� rw rw )rH rx r/ s .6 #c sF e Zd ZdZeejd��Zd � fdd� Zd dd�Z � fd d �Z � Z S ) r' a� Token for matching strings that match a given regular expression.

When the expression is known, it is assigned to the C{Forward} variable using the '<<' operator. Note: take care when assigning to C{Forward} not to overlook precedence of operators. Specifically, '|' has a lower precedence than '<<', so that:: fwdExpr << a | b | c will actually be evaluated as:: (fwdExpr << a) | b | c thereby leaving b and c out as parseable alternatives. It is recommended that you explicitly group the values inserted into the C{Forward}:: fwdExpr << (a | b | c) Converting to use the '<<=' operator instead will avoid this problem.

By default, the list elements and delimiters can have intervening whitespace, and comments, but this can be overridden by passing C{combine=True} in the constructor. If C{combine} is set to C{True}, the matching tokens are returned as a single token string, with the delimiters included; otherwise, the matching tokens are returned as a list of tokens, with the delimiters suppressed. Example:: delimitedList(Word(alphas)).parseString("aa,bb,cc") # -> ['aa', 'bb', 'cc'] delimitedList(Word(hexnums), delim=':', combine=True).parseString("AA:BB:CC:DD:EE") # -> ['AA:BB:CC:DD:EE'] z [r� z]...N)r� r r2 ri r+ )r.

This helper defines a pattern of the form:: integer expr expr expr... where the leading integer tells how many expr expressions follow. The matched tokens returns the array of expr tokens as a list - the leading count token is suppressed. If C{intExpr} is specified, it should be a pyparsing expression that produces an integer value. Example:: countedArray(Word(alphas)).parseString('2 ab cd ef') # -> ['ab', 'cd'] # in this parser, the leading integer value is given in binary, # '10' indicating that 2 values are in the array binaryConstant = Word('01').setParseAction(lambda t: int(t[0], 2)) countedArray(Word(alphas), intExpr=binaryConstant).parseString('10 ab cd ef') # -> ['ab', 'cd'] c s. |d }� |r t t�g| ��p&t t�> g S )Nr )r r rC )r� r5 rv r� )� arrayExprr. rw rx �countFieldParseAction_ s "z+countedArray.<locals>.countFieldParseActionNc S s t | d �S )Nr )ru )rv rw rw rx ry d s z countedArray.<locals>.<lambda>ZarrayLenT)rf z(len) z...)r r/ rR r� r� ri rx r� )r.

Parameters: - strs - a string of space-delimited literals, or a collection of string literals - caseless - (default=C{False}) - treat all literals as caseless - useRegex - (default=C{True}) - as an optimization, will generate a Regex object; otherwise, will generate a C{MatchFirst} object (if C{caseless=True}, or if creating a C{Regex} raises an exception) Example:: comp_oper = oneOf("< = > <= >= !=") var = Word(alphas) number = Word(nums) term = var | number comparison_expr = term + comp_oper + term print(comparison_expr.searchString("B = 12 AA=23 B<=AA AA>12")) prints:: [['B', '=', '12'], ['AA', '=', '23'], ['B', '<=', 'AA'], ['AA', '>', '12']] c S s | j � |j � kS )N)r� )r �brw rw rx ry � s zoneOf.<locals>.<lambda>c S s |j � j| j � �S )N)r� r� )r rk rw rw rx ry � s c S s | |kS )Nrw )r rk rw rw rx ry � s c S s |j | �S )N)r� )r rk rw rw rx ry � s z6Invalid argument to oneOf, expected string or iterablerq )r� r rr Nr� z[%s]c s s | ]}t |�V qd S )N)r )r� �symrw rw rx r� � s zoneOf.<locals>.<genexpr>z | �|c s s | ]}t j|�V qd S )N)rd r )r� rl rw rw rx r� � s z7Exception creating Regex for oneOf, building MatchFirstc 3 s | ]}� |�V qd S )Nrw )r� rl )�parseElementClassrw rx r� � s )r r rz r� r� r� r4 r� r� r� r� r r� r� r� r� r' ri rK r ) Zstrsr� ZuseRegexZisequalZmasksZsymbolsr� Zcurr� r� rw )rn rx rS � sL ((c C s t tt| | ���S )a� Helper to easily and clearly define a dictionary by specifying the respective patterns for the key and value. Takes care of defining the C{L{Dict}}, C{L{ZeroOrMore}}, and C{L{Group}} tokens in the proper order. The key pattern can include delimiting markers or punctuation, as long as they are suppressed, thereby leaving the significant key text. The value pattern can include named results, so that the C{Dict} results can include named token fields. Example:: text = "shape: SQUARE posn: upper left color: light blue texture: burlap" attr_expr = (label + Suppress(':') + OneOrMore(data_word, stopOn=label).setParseAction(' '.join)) print(OneOrMore(attr_expr).parseString(text).dump()) attr_label = label attr_value = Suppress(':') + OneOrMore(data_word, stopOn=label).setParseAction(' '.join) # similar to Dict, but simpler call format result = dictOf(attr_label, attr_value).parseString(text) print(result.dump()) print(result['shape']) print(result.shape) # object attribute access works too print(result.asDict()) prints:: [['shape', 'SQUARE'], ['posn', 'upper left'], ['color', 'light blue'], ['texture', 'burlap']] - color: light blue - posn: upper left - shape: SQUARE - texture: burlap SQUARE SQUARE {'color': 'light blue', 'shape': 'SQUARE', 'posn': 'upper left', 'texture': 'burlap'} )r r2 r )r� r� rw rw rx rA � s !c C s^ t � jdd� �}|j� }d|_|d�| |d� }|r@dd� }ndd� }|j|� | j|_|S ) a� Helper to return the original, untokenized text for a given expression. Useful to restore the parsed fields of an HTML start tag into the raw tag text itself, or to revert separate tokens with intervening whitespace back to the original matching input text. By default, returns astring containing the original parsed text. If the optional C{asString} argument is passed as C{False}, then the return value is a C{L{ParseResults}} containing any results names that were originally matched, and a single token containing the original matched text from the input string. So if the expression passed to C{L{originalTextFor}} contains expressions with defined results names, you must set C{asString} to C{False} if you want to preserve those results name values. Example:: src = "this is test <b> bold <i>text</i> </b> normal text " for tag in ("b","i"): opener,closer = makeHTMLTags(tag) patt = originalTextFor(opener + SkipTo(closer) + closer) print(patt.searchString(src)[0]) prints:: ['<b> bold <i>text</i> </b>'] ['<i>text</i>'] c S s |S )Nrw )r� r� rv rw rw rx ry 8 s z!originalTextFor.<locals>.<lambda>F�_original_start� _original_endc S s | |j |j� S )N)ro rp )r� r5 rv rw rw rx ry = s c S s& | |j d�|j d�� g|d d �< d S )Nro rp )r� )r� r5 rv rw rw rx � extractText? s z$originalTextFor.<locals>.extractText)r r� r� re r] )r.

Borrows syntax from regexp '[]' string range definitions:: srange("[0-9]") -> "0123456789" srange("[a-z]") -> "abcdefghijklmnopqrstuvwxyz" srange("[a-z$_]") -> "abcdefghijklmnopqrstuvwxyz$_" The input string must be enclosed in []'s, and the returned string is the expanded character set joined into a single string. The values enclosed in the []'s may be: - a single character - an escaped character with a leading backslash (such as C{\-} or C{\]}) - an escaped hex character with a leading C{'\x'} (C{\x21}, which is a C{'!'} character) (C{\0x##} is also supported for backwards compatibility) - an escaped octal character with a leading C{'\0'} (C{\041}, which is a C{'!'} character) - a range of any of the above, separated by a dash (C{'a-z'}, etc.) - any combination of the above (C{'aeiouy'}, C{'a-zA-Z0-9_$'}, etc.) c S s< t | t�s| S djdd� tt| d �t| d �d �D ��S )Nr� c s s | ]}t |�V qd S )N)rt )r� r� rw rw rx r� � s z+srange.<locals>.<lambda>.<locals>.<genexpr>r rr )rz r" r� r� �ord)�prw rw rx ry � s zsrange.<locals>.<lambda>r� c 3 s | ]}� |�V qd S )Nrw )r� �part)� _expandedrw rx r� � s zsrange.<locals>.<genexpr>N)r� �_reBracketExprr� rw rK )r� rw )r{ rx r_ r s c s � fdd�}|S )zt Helper method for defining parse actions that require matching at a specific column in the input text. c s" t || �� kr t| |d� ��d S )Nz matched token not at column %d)r9 r )r) Zlocnr1 )r� rw rx � verifyCol� s z!matchOnlyAtCol.<locals>.verifyColrw )r� r} rw )r� rx rM � s c s � fdd�S )a� Helper method for common parse actions that simply return a literal value.

Use C{withAttribute} to qualify a starting tag with a required attribute value, to avoid false matches on common tags such as C{<TD>} or C{<DIV>}. Call C{withAttribute} with a series of attribute names and values. Specify the list of filter attributes names and values as: - keyword arguments, as in C{(align="right")}, or - as an explicit dict with C{**} operator, when an attribute name is also a Python reserved word, as in C{**{"class":"Customer", "align":"right"}} - a list of name-value tuples, as in ( ("ns1:class", "Customer"), ("ns2:align","right") ) For attribute names with a namespace prefix, you must use the second form. Attribute names are matched insensitive to upper/lower case. If just testing for C{class} (with or without a namespace), use C{L{withClass}}. To verify that the attribute exists, but without specifying a value, pass C{withAttribute.ANY_VALUE} as the value. Example:: html = ''' <div> Some text <div type="grid">1 4 0 1 0</div> <div type="graph">1,3 2,3 1,1</div> <div>this has no type</div> </div> ''' div,div_end = makeHTMLTags("div") # only match div tag having a type attribute with value "grid" div_grid = div().setParseAction(withAttribute(type="grid")) grid_expr = div_grid + SkipTo(div | div_end)("body") for grid_header in grid_expr.searchString(html): print(grid_header.body) # construct a match with any div tag having a type attribute, regardless of the value div_any_type = div().setParseAction(withAttribute(type=withAttribute.ANY_VALUE)) div_expr = div_any_type + SkipTo(div | div_end)("body") for div_header in div_expr.searchString(html): print(div_header.body) prints:: 1 4 0 1 0 1 4 0 1 0 1,3 2,3 1,1 Nc S s g | ]\}}||f�qS rw rw )r� r� r� rw rw rx r� Q s z!withAttribute.<locals>.<listcomp>c s^ xX� D ]P\}}||kr&t | |d| ��|tjkr|| |krt | |d||| |f ��qW d S )Nzno matching attribute z+attribute '%s' has value '%s', must be '%s')r re � ANY_VALUE)r� r5 r� ZattrNameZ attrValue)�attrsrw rx r} R s zwithAttribute.<locals>.pa)r� )r� ZattrDictr} rw )r� rx re s 2 c C s |r d| nd}t f || i�S )a� Simplified version of C{L{withAttribute}} when matching on a div class - made difficult because C{class} is a reserved word in Python.

Operators may be unary or binary, left- or right-associative. Parse actions can also be attached to operator expressions. The generated parser will also recognize the use of parentheses to override operator precedences (see example below). Note: if you define a deep operator list, you may see performance issues when using infixNotation. See L{ParserElement.enablePackrat} for a mechanism to potentially improve your parser performance. Parameters: - baseExpr - expression representing the most basic element for the nested - opList - list of tuples, one for each operator precedence level in the expression grammar; each tuple is of the form (opExpr, numTerms, rightLeftAssoc, parseAction), where: - opExpr is the pyparsing expression for the operator; may also be a string, which will be converted to a Literal; if numTerms is 3, opExpr is a tuple of two expressions, for the two operators separating the 3 terms - numTerms is the number of terms for this operator (must be 1, 2, or 3) - rightLeftAssoc is the indicator whether the operator is right or left associative, using the pyparsing-defined constants C{opAssoc.RIGHT} and C{opAssoc.LEFT}. - parseAction is the parse action to be associated with expressions matching this operator expression (the parse action tuple member may be omitted) - lpar - expression for matching left-parentheses (default=C{Suppress('(')}) - rpar - expression for matching right-parentheses (default=C{Suppress(')')}) Example:: # simple example of four-function arithmetic with ints and variable names integer = pyparsing_common.signed_integer varname = pyparsing_common.identifier arith_expr = infixNotation(integer | varname, [ ('-', 1, opAssoc.RIGHT), (oneOf('* /'), 2, opAssoc.LEFT), (oneOf('+ -'), 2, opAssoc.LEFT), ]) arith_expr.runTests(''' 5+3*6 (5+3)*6 -2--11 ''', fullDump=False) prints:: 5+3*6 [[5, '+', [3, '*', 6]]] (5+3)*6 [[[5, '+', 3], '*', 6]] -2--11 [[['-', 2], '-', ['-', 11]]] Nr ro z%s termz %s%s termrq z@if numterms=3, opExpr must be a tuple or list of two expressionsrr z6operator must be unary (1), binary (2), or ternary (3)z2operator must indicate right or left associativity)N)r r� r� r� ri rT �LEFTr r r �RIGHTrz r r. r� )ZbaseExprZopListZlparZrparr� ZlastExprr� ZoperDefZopExprZarityZrightLeftAssocr} ZtermNameZopExpr1ZopExpr2ZthisExprrr rw rw rx ri � sR ; & & z4"(?:[^"\n\r\\]|(?:"")|(?:\\(?:[^x]|x[0-9a-fA-F]+)))*�"z string enclosed in double quotesz4'(?:[^'\n\r\\]|(?:'')|(?:\\(?:[^x]|x[0-9a-fA-F]+)))*�'z string enclosed in single quotesz*quotedString using single or double quotes�uzunicode string literalc C s� | |krt d��|dk�r(t| t�o,t|t��r t| �dkr�t|�dkr�|dk r�tt| t| | tj dd� ��j dd� �}n$t j � t| | tj �j dd� � }nx|dk r�tt| t | � t |� ttjdd� ��j dd� �}n4ttt | � t |� ttjdd� ��j d d� �}nt d ��t � }|dk �rb|tt| �t||B |B � t|� �K }n$|tt| �t||B � t|� �K }|jd | |f � |S ) a~ Helper method for defining nested lists enclosed in opening and closing delimiters ("(" and ")" are the default). Parameters: - opener - opening character for a nested list (default=C{"("}); can also be a pyparsing expression - closer - closing character for a nested list (default=C{")"}); can also be a pyparsing expression - content - expression for items within the nested lists (default=C{None}) - ignoreExpr - expression for ignoring opening and closing delimiters (default=C{quotedString}) If an expression is not provided for the content argument, the nested expression will capture all whitespace-delimited content between delimiters as a list of separate values. Use the C{ignoreExpr} argument to define expressions that may contain opening or closing characters that should not be treated as opening or closing characters for nesting, such as quotedString or a comment expression. Specify multiple expressions using an C{L{Or}} or C{L{MatchFirst}}. The default is L{quotedString}, but if no expressions are to be ignored, then pass C{None} for this argument. Example:: data_type = oneOf("void int short long char float double") decl_data_type = Combine(data_type + Optional(Word('*'))) ident = Word(alphas+'_', alphanums+'_') number = pyparsing_common.number arg = Group(decl_data_type + ident) LPAR,RPAR = map(Suppress, "()") code_body = nestedExpr('{', '}', ignoreExpr=(quotedString | cStyleComment)) c_function = (decl_data_type("type") + ident("name") + LPAR + Optional(delimitedList(arg), [])("args") + RPAR + code_body("body")) c_function.ignore(cStyleComment) source_code = ''' int is_odd(int x) { return (x%2); } int dec_to_hex(char hchar) { if (hchar >= '0' && hchar <= '9') { return (ord(hchar)-ord('0')); } else { return (10+ord(hchar)-ord('A')); } } ''' for func in c_function.searchString(source_code): print("%(name)s (%(type)s) args: %(args)s" % func) prints:: is_odd (int) args: [['int', 'x']] dec_to_hex (int) args: [['char', 'hchar']] z.opening and closing strings cannot be the sameNrr )r c S s | d j � S )Nr )r� )rv rw rw rx ry 9 s z nestedExpr.<locals>.<lambda>c S s | d j � S )Nr )r� )rv rw rw rx ry < s c S s | d j � S )Nr )r� )rv rw rw rx ry B s c S s | d j � S )Nr )r� )rv rw rw rx ry F s zOopening and closing arguments must be strings if no content expression is givenznested %s%s expression)r� rz r� r� r r r r$ rN r� rC r� r r r r+ r2 ri )�openerZcloserZcontentrN r� rw rw rx rP � s4 : *$c s� � fdd�}� fdd�}� fdd�}t t� jd�j� �}t� t� j|� jd�}t� j|�jd �}t� j|�jd �} |r�tt|�| t |t| � t|� � | �} n$tt|�t |t| � t|� � �} | j t t� � | jd �S ) a Helper method for defining space-delimited indentation blocks, such as those used to define block statements in Python source code.

If unspecified, +00:00 is used. :param dstabbr: The abbreviation for DST / "Summer" time (e.g. ``'EDT'``). If specified, with no other DST information, DST is assumed to occur and the default behavior or ``dstoffset``, ``start`` and ``end`` is used. If unspecified and no other DST information is specified, it is assumed that this zone has no DST. If this is unspecified and other DST information is *is* specified, DST occurs in the zone but the time zone abbreviation is left unchanged. :param dstoffset: A an integer or :class:`datetime.timedelta` object or equivalent specifying the UTC offset during DST. If unspecified and any other DST information is specified, it is assumed to be the STD offset +1 hour. :param start: A :class:`relativedelta.relativedelta` object or equivalent specifying the time and time of year that daylight savings time starts. To specify, for example, that DST starts at 2AM on the 2nd Sunday in March, pass: ``relativedelta(hours=2, month=3, day=1, weekday=SU(+2))`` If unspecified and any other DST information is specified, the default value is 2 AM on the first Sunday in April. :param end: A :class:`relativedelta.relativedelta` object or equivalent representing the time and time of year that daylight savings time ends, with the same specification method as in ``start``. One note is that this should point to the first time in the *standard* zone, so if a transition occurs at 2AM in the DST zone and the clocks are set back 1 hour to 1AM, set the `hours` parameter to +1. **Examples:** .. testsetup:: tzrange from dateutil.tz import tzrange, tzstr .. doctest:: tzrange >>> tzstr('EST5EDT') == tzrange("EST", -18000, "EDT") True >>> from dateutil.relativedelta import * >>> range1 = tzrange("EST", -18000, "EDT") >>> range2 = tzrange("EST", -18000, "EDT", -14400, ... relativedelta(hours=+2, month=4, day=1, ... weekday=SU(+1)), ... relativedelta(hours=+1, month=10, day=31, ... weekday=SU(-1))) >>> tzstr('EST5EDT') == range1 == range2 True Nc C s@ ddl ma || _|| _y t|�}W n ttfk r< Y nX y t|�}W n ttfk rb Y nX |d k r|tj|d�| _ nt | _ |d k r�tj|d�| _ n(|r�|d k r�| j tjd d� | _ nt | _ |r�|d kr�tjd ddtj d �d�| _ n|| _ |�r |d k�r tjdd d tj d�d�| _n|| _| j | j | _t| j �| _d S )Nr )� relativedelta)r( r )�hours� rn )r� �month�day�weekday� � r r� r r rz )�dateutilr� � _std_abbr� _dst_abbrr r* r+ r, r- r7 r r8 �SU� _start_delta� _end_delta�_dst_base_offset_r: �hasdst)r �stdabbr� stdoffset�dstabbrrK �start�endr r r r0 J s: ztzrange.__init__c C s4 | j s dS tj|dd�}|| j }|| j }||fS )a� For a given year, get the DST on and off transition times, expressed always on the standard time side.

There is one notable exception, which is that POSIX-style time zones use an inverted offset format, so normally ``GMT+3`` would be parsed as an offset 3 hours *behind* GMT. The ``tzstr`` time zone object will parse this as an offset 3 hours *ahead* of GMT. If you would like to maintain the POSIX behavior, pass a ``True`` value to ``posix_offset``. The :class:`tzrange` object provides the same functionality, but is specified using :class:`relativedelta.relativedelta` objects. rather than strings. :param s: A time zone string in ``TZ`` variable format. This can be a :class:`bytes` (2.x: :class:`str`), :class:`str` (2.x: :class:`unicode`) or a stream emitting unicode characters (e.g. :class:`StringIO`). :param posix_offset: Optional. If set to ``True``, interpret strings such as ``GMT+3`` or ``UTC+3`` as being 3 hours *behind* UTC rather than ahead, per the POSIX standard. .. _`GNU C Library: TZ Variable`: https://www.gnu.org/software/libc/manual/html_node/TZ-Variable.html Fc C s� ddl ma || _tj|�}|d kr,td��|jd krJ| rJ| jd 9 _tj| |j|j|j |j ddd� |j s~d | _ d | _ n&| j |j�| _ | j r�| j |jdd �| _ t| j �| _d S ) Nr )�parserzunknown string format�GMTr r F)r� r� )�isend)r� r rz )r� r� �_sZ_parsetzr} r� r� r� r0 r� rK r� r� �_deltar� r� r: r� )r �sZ posix_offset�resr r r r0 � s" ztzstr.__init__r c C s< ddl m} i }|jd k rr|j|d< |jd k r`|j|j|j�|d< |jdkrVd|d< qpd|d< q�|jr�|j|d< n*|jd k r�|j|d< n|jd k r�|j|d < |s�|s�d |d< d|d< |jd�|d< n d |d< d|d< |jd�|d< |j d k � r�|j |d < nd |d < |�r0| j | j }|d |j |j d 8 < |jf |�S )Nr )r� r� r� r r� r� ZyeardayZ nlyeardayrn r� r( i i�Q r rz )r� r� r� r� Zweekr� ZydayZjydayr� r5 r8 r7 r( Zdays)r �xr� r� ra rF r r r r� � s< z tzstr._deltac C s d| j jt| j�f S )Nz%s(%s))r r r1 r� )r r r r r! s ztzstr.__repr__N)F)r )r r" r# r$ r0 r� r! r r r r r� � s )r� c @ s e Zd Zddd�ZdS )�_tzicalvtzcompNc C s@ t j|d�| _t j|d�| _| j| j | _|| _|| _|| _d S )N)r( )r, r- � tzoffsetfrom� tzoffsetto� tzoffsetdiffrG r �rrule)r r� r� rG r r� r r r r0 s z_tzicalvtzcomp.__init__)NN)r r" r# r0 r r r r r� s r� c sZ e Zd Zg f� fdd� Zdd� Zdd� Zdd� Zd d � Zed d � �Z d d� Z e j Z � Z S )� _tzicalvtzc s* t t| �j� || _|| _g | _g | _d S )N)r4 r� r0 �_tzid�_comps� _cachedate� _cachecomp)r �tzid�comps)r r r r0 s z_tzicalvtz.__init__c C s t | j�dkr| jd S |jd d�}y | j| jj|| j|�f� S tk rT Y nX d }d }x4| jD ]*}| j||�}|rf| s�||k rf|}|}qfW |s�x"| jD ]}|j s�|}P q�W |d }| jj d|| j|�f� | jj d|� t | j�dk�r| jj � | jj � |S )Nr r )r� r� ) r� r� �replacer� r� �indexrC r} � _find_compdtrG �insert�pop)r r Z lastcompdtZlastcomp�comp�compdtr r r � _find_comp s4 z_tzicalvtz._find_compc C s2 |j tk r | j|�r ||j 8 }|jj|dd�}|S )NT)Zinc)r� r rC r� Zbefore)r r� r r� r r r r� I s z_tzicalvtz._find_compdtc C s |d kr d S | j |�jS )N)r� r� )r r r r r r Q s z_tzicalvtz.utcoffsetc C s | j |�}|jr|jS tS d S )N)r� rG r� r )r r r� r r r r W s z_tzicalvtz.dstc C s | j |�jS )N)r� r )r r r r r r ^ s z_tzicalvtz.tznamec C s dt | j� S )Nz<tzicalvtz %s>)r1 r� )r r r r r! b s z_tzicalvtz.__repr__)r r" r# r0 r� r� r r r r r! r& r' rD r r )r r r� s * r� c @ sB e Zd ZdZdd� Zdd� Zddd�Zd d � Zd d � Zd d� Z dS )�tzicala\ This object is designed to parse an iCalendar-style ``VTIMEZONE`` structure as set out in `RFC 2445`_ Section 4.6.5 into one or more `tzinfo` objects. :param `fileobj`: A file or stream in iCalendar format, which should be UTF-8 encoded with CRLF endings. .. _`RFC 2445`: https://www.ietf.org/rfc/rfc2445.txt c C sj ddl ma t|t�r(|| _t|d�}nt|dt|��| _t|�}i | _ |�}| j |j � � W d Q R X d S )Nr )r� �rr. ) r� r� r r r� re rB r1 rg �_vtz� _parse_rfcr{ )r rj Zfobjr r r r0 s s ztzical.__init__c C s t | jj� �S )z?

If unspecified, +00:00 is used. :param dstabbr: The abbreviation for DST / "Summer" time (e.g. ``'EDT'``). If specified, with no other DST information, DST is assumed to occur and the default behavior or ``dstoffset``, ``start`` and ``end`` is used. If unspecified and no other DST information is specified, it is assumed that this zone has no DST. If this is unspecified and other DST information is *is* specified, DST occurs in the zone but the time zone abbreviation is left unchanged. :param dstoffset: A an integer or :class:`datetime.timedelta` object or equivalent specifying the UTC offset during DST. If unspecified and any other DST information is specified, it is assumed to be the STD offset +1 hour. :param start: A :class:`relativedelta.relativedelta` object or equivalent specifying the time and time of year that daylight savings time starts. To specify, for example, that DST starts at 2AM on the 2nd Sunday in March, pass: ``relativedelta(hours=2, month=3, day=1, weekday=SU(+2))`` If unspecified and any other DST information is specified, the default value is 2 AM on the first Sunday in April. :param end: A :class:`relativedelta.relativedelta` object or equivalent representing the time and time of year that daylight savings time ends, with the same specification method as in ``start``. One note is that this should point to the first time in the *standard* zone, so if a transition occurs at 2AM in the DST zone and the clocks are set back 1 hour to 1AM, set the `hours` parameter to +1. **Examples:** .. testsetup:: tzrange from dateutil.tz import tzrange, tzstr .. doctest:: tzrange >>> tzstr('EST5EDT') == tzrange("EST", -18000, "EDT") True >>> from dateutil.relativedelta import * >>> range1 = tzrange("EST", -18000, "EDT") >>> range2 = tzrange("EST", -18000, "EDT", -14400, ... relativedelta(hours=+2, month=4, day=1, ... weekday=SU(+1)), ... relativedelta(hours=+1, month=10, day=31, ... weekday=SU(-1))) >>> tzstr('EST5EDT') == range1 == range2 True Nc C s@ ddl ma || _|| _y t|�}W n ttfk r< Y nX y t|�}W n ttfk rb Y nX |d k r|tj|d�| _ nt | _ |d k r�tj|d�| _ n(|r�|d k r�| j tjd d� | _ nt | _ |r�|d kr�tjd ddtj d �d�| _ n|| _ |�r |d k�r tjdd d tj d�d�| _n|| _| j | j | _t| j �| _d S )Nr )� relativedelta)r( r )�hours� rn )r� �month�day�weekday� � r r� r r rz )�dateutilr� � _std_abbr� _dst_abbrr r* r+ r, r- r7 r r8 �SU� _start_delta� _end_delta�_dst_base_offset_r: �hasdst)r �stdabbr� stdoffset�dstabbrrK �start�endr r r r0 J s: ztzrange.__init__c C s4 | j s dS tj|dd�}|| j }|| j }||fS )a� For a given year, get the DST on and off transition times, expressed always on the standard time side.

There is one notable exception, which is that POSIX-style time zones use an inverted offset format, so normally ``GMT+3`` would be parsed as an offset 3 hours *behind* GMT. The ``tzstr`` time zone object will parse this as an offset 3 hours *ahead* of GMT. If you would like to maintain the POSIX behavior, pass a ``True`` value to ``posix_offset``.

This module attempts to be forgiving with regards to unlikely input formats, returning a datetime object even for dates which are ambiguous. If an element of a date/time stamp is omitted, the following rules are applied: - If AM or PM is left unspecified, a 24-hour clock is assumed, however, an hour on a 12-hour clock (``0 <= hour <= 12``) *must* be specified if AM or PM is specified. - If a time zone is omitted, a timezone-naive datetime is returned. If any other elements are missing, they are taken from the :class:`datetime.datetime` object passed to the parameter ``default``. If this results in a day number exceeding the valid number of days per month, the value falls back to the end of the month.

Lexical units are demarcated by changes in the character set, so any continuous string of letters is considered one unit, any continuous string of numbers is considered one unit. The main complication arises from the fact that dots ('.') can be used both as separators (e.g. "Sep.20.2009") or decimal points (e.g. "4:30:21.447"). As such, it is necessary to read the full context of any dot-separated strings before breaking it into tokens; as such, this function maintains a "token stack", for when the ambiguous context demands that multiple tokens be parsed at once. r FNr � T�a�0� �.�a.�,� �0.z.,���r' )r# r& r' )r �popr r r r �isword�isnum�isspace�append�len�count�_split_decimal�split�replace)r Z seenletters�token�state�nextchar�l�tokr r r � get_tokenD s� " z_timelex.get_tokenc C s | S )Nr )r r r r �__iter__� s z_timelex.__iter__c C s | j � }|d krt�|S )N)r7 � StopIteration)r r2 r r r �__next__� s z_timelex.__next__c C s | j � S )N)r: )r r r r �next� s z _timelex.nextc C s t | |��S )N)�list)�cls�sr r r r0 � s z_timelex.splitc C s |j � S )z5 Whether or not the next character is part of a word )�isalpha)r= r4 r r r r) � s z_timelex.iswordc C s |j � S )z0 Whether the next character is part of a number )�isdigit)r= r4 r r r r* � s z_timelex.isnumc C s |j � S )z* Whether the next character is whitespace )r+ )r= r4 r r r r+ � s z_timelex.isspaceN)r � __module__� __qualname__�re�compiler/ r r7 r8 r: r; � classmethodr0 r) r* r+ r r r r r 0 s m r c @ s, e Zd Zdd� Zdd� Zdd� Zdd� Zd S ) � _resultbasec C s x| j D ]}t| |d � qW d S )N)� __slots__�setattr)r �attrr r r r � s z_resultbase.__init__c C sN g }x6| j D ],}t| |�}|d k r |jd|t|�f � q W d|dj|�f S )Nz%s=%sz%s(%s)z, )rG r r, �repr�join)r Z classnamer5 rI �valuer r r �_repr� s z_resultbase._reprc s t � fdd�� jD ��S )Nc 3 s | ]}t � |�d k V qd S )N)r )�.0rI )r r r � <genexpr>� s z&_resultbase.__len__.<locals>.<genexpr>)�sumrG )r r )r r �__len__� s z_resultbase.__len__c C s | j | jj�S )N)rM r r )r r r r �__repr__� s z_resultbase.__repr__N)r rA rB r rM rQ rR r r r r rF � s rF c @ s� e Zd ZdZdddddddd d d d d ddddddgZdcdddedfdgdhdigZdjdkdldmdndodpdqdrdsdtdug ZdvdwdxgZdydzgZdFdGdHgZ dgZ i Z d{dJdK�Z dLdM� Z dNdO� ZdPdQ� ZdRdS� ZdTdU� ZdVdW� ZdXdY� ZdZd[� Zd\d]� Zd|d^d_�Zd`da� ZdbS )}r a� Class which handles what inputs are accepted.

Lemburg in his `mx.DateTime <http://www.egenix.com/files/python/mxDateTime.html>`_ extension. However, notice that this type does *NOT* implement the same algorithm as his work. Do *NOT* expect it to behave like mx.DateTime's counterpart. There are two different ways to build a relativedelta instance. The first one is passing it two date/datetime classes:: relativedelta(datetime1, datetime2) The second one is passing it any number of the following keyword arguments:: relativedelta(arg1=x,arg2=y,arg3=z...) year, month, day, hour, minute, second, microsecond: Absolute information (argument is singular); adding or subtracting a relativedelta with absolute information does not perform an aritmetic operation, but rather REPLACES the corresponding value in the original datetime with the value(s) in relativedelta. years, months, weeks, days, hours, minutes, seconds, microseconds: Relative information, may be negative (argument is plural); adding or subtracting a relativedelta with relative information performs the corresponding aritmetic operation on the original datetime value with the information in the relativedelta. weekday: One of the weekday instances (MO, TU, etc). These instances may receive a parameter N, specifying the Nth weekday, which could be positive or negative (like MO(+1) or MO(-2). Not specifying it is the same as specifying +1. You can also use an integer, where 0=MO. leapdays: Will add given days to the date found, if year is a leap year, and the date found is post 28 of february. yearday, nlyearday: Set the yearday or the non-leap year day (jump leap days). These are converted to day/month/leapdays information. Here is the behavior of operations with relativedelta: 1. Calculate the absolute year, using the 'year' argument, or the original datetime year, if the argument is not present. 2. Add the relative 'years' argument to the absolute year. 3. Do steps 1 and 2 for month/months. 4. Calculate the absolute day, using the 'day' argument, or the original datetime day, if the argument is not present. Then, subtract from the day until it fits in the year and month found after their operations. 5. Add the relative 'days' argument to the absolute day. Notice that the 'weeks' argument is multiplied by 7 and added to 'days'. 6. Do steps 1 and 2 for hour/hours, minute/minutes, second/seconds, microsecond/microseconds. 7. If the 'weekday' argument is present, calculate the weekday, with the given (wday, nth) tuple. wday is the index of the weekday (0-6, 0=Mon), and nth is the number of weeks to add forward or backward, depending on its signal. Notice that if the calculated date is already Monday, for example, using (0, 1) or (0, -1) won't change the day.

work done by GM Arts, on top of the algorithm by Claus Tondering, which was based in part on the algorithm of Ouding (1940), as quoted in "Explanatory Supplement to the Astronomical Almanac", P. Kenneth Seidelmann, editor. This algorithm implements three different easter calculation methods: 1 - Original calculation in Julian calendar, valid in dates after 326 AD 2 - Original method, with date converted to Gregorian calendar, valid in years 1583 to 4099 3 - Revised method, in Gregorian calendar, valid in years 1583 to 4099 as well These methods are represented by the constants: * ``EASTER_JULIAN = 1`` * ``EASTER_ORTHODOX = 2`` * ``EASTER_WESTERN = 3`` The default method is method 3.

It accepts all the keywords defined in the RFC as its constructor parameters (except byday, which was renamed to byweekday) and more. The constructor prototype is:: rrule(freq) Where freq must be one of YEARLY, MONTHLY, WEEKLY, DAILY, HOURLY, MINUTELY, or SECONDLY. .. note:: Per RFC section 3.3.10, recurrence instances falling on invalid dates and times are ignored rather than coerced: Recurrence rules may generate recurrence instances with an invalid date (e.g., February 30) or nonexistent local time (e.g., 1:30 AM on a day where the local time is moved forward by an hour at 1:00 AM). Such recurrence instances MUST be ignored and MUST NOT be counted as part of the recurrence set. This can lead to possibly surprising behavior when, for example, the start date occurs at the end of the month: >>> from dateutil.rrule import rrule, MONTHLY >>> from datetime import datetime >>> start_date = datetime(2014, 12, 31) >>> list(rrule(freq=MONTHLY, count=4, dtstart=start_date)) ... # doctest: +NORMALIZE_WHITESPACE [datetime.datetime(2014, 12, 31, 0, 0), datetime.datetime(2015, 1, 31, 0, 0), datetime.datetime(2015, 3, 31, 0, 0), datetime.datetime(2015, 5, 31, 0, 0)] Additionally, it supports the following keyword arguments: :param cache: If given, it must be a boolean value specifying to enable or disable caching of results. If you will use the same rrule instance multiple times, enabling caching will improve the performance considerably. :param dtstart: The recurrence start. Besides being the base for the recurrence, missing parameters in the final recurrence instances will also be extracted from this date. If not given, datetime.now() will be used instead. :param interval: The interval between each freq iteration. For example, when using YEARLY, an interval of 2 means once every two years, but with HOURLY, it means once every two hours. The default interval is 1. :param wkst: The week start day. Must be one of the MO, TU, WE constants, or an integer, specifying the first day of the week. This will affect recurrences based on weekly periods. The default week start is got from calendar.firstweekday(), and may be modified by calendar.setfirstweekday(). :param count: How many occurrences will be generated. .. note:: As of version 2.5.0, the use of the ``until`` keyword together with the ``count`` keyword is deprecated per RFC-2445 Sec. 4.3.10. :param until: If given, this must be a datetime instance, that will specify the limit of the recurrence. The last recurrence in the rule is the greatest datetime that is less than or equal to the value specified in the ``until`` parameter. .. note:: As of version 2.5.0, the use of the ``until`` keyword together with the ``count`` keyword is deprecated per RFC-2445 Sec. 4.3.10. :param bysetpos: If given, it must be either an integer, or a sequence of integers, positive or negative. Each given integer will specify an occurrence number, corresponding to the nth occurrence of the rule inside the frequency period. For example, a bysetpos of -1 if combined with a MONTHLY frequency, and a byweekday of (MO, TU, WE, TH, FR), will result in the last work day of every month. :param bymonth: If given, it must be either an integer, or a sequence of integers, meaning the months to apply the recurrence to. :param bymonthday: If given, it must be either an integer, or a sequence of integers, meaning the month days to apply the recurrence to. :param byyearday: If given, it must be either an integer, or a sequence of integers, meaning the year days to apply the recurrence to. :param byweekno: If given, it must be either an integer, or a sequence of integers, meaning the week numbers to apply the recurrence to. Week numbers have the meaning described in ISO8601, that is, the first week of the year is that containing at least four days of the new year. :param byweekday: If given, it must be either an integer (0 == MO), a sequence of integers, one of the weekday constants (MO, TU, etc), or a sequence of these constants. When given, these variables will define the weekdays where the recurrence will be applied. It's also possible to use an argument n for the weekday instances, which will mean the nth occurrence of this weekday in the period. For example, with MONTHLY, or with YEARLY and BYMONTH, using FR(+1) in byweekday will specify the first friday of the month where the recurrence happens. Notice that in the RFC documentation, this is specified as BYDAY, but was renamed to avoid the ambiguity of that keyword. :param byhour: If given, it must be either an integer, or a sequence of integers, meaning the hours to apply the recurrence to. :param byminute: If given, it must be either an integer, or a sequence of integers, meaning the minutes to apply the recurrence to. :param bysecond: If given, it must be either an integer, or a sequence of integers, meaning the seconds to apply the recurrence to. :param byeaster: If given, it must be either an integer, or a sequence of integers, positive or negative. Each integer will define an offset from the Easter Sunday. Passing the offset 0 to byeaster will yield the Easter Sunday itself. This is an extension to the RFC specification.

This occurs whenever the interval is not coprime with the base of a given unit and the difference between the starting position and the ending position is not coprime with the greatest common denominator between the interval and the base. For example, with a FREQ of hourly starting at 17:00 and an interval of 4, the only valid values for BYHOUR would be {21, 1, 5, 9, 13, 17}, because 4 and 24 are not coprime. :param start: Specifies the starting position. :param byxxx: An iterable containing the list of allowed values. :param base: The largest allowable value for the specified frequency (e.g. 24 hours, 60 minutes). This does not preserve the type of the iterable, returning a set, since the values should be unique and the order is irrelevant, this will speed up later lookups. In the event of an empty set, raises a :exception:`ValueError`, as this results in an empty rrule. r r z+Invalid rrule byxxx generates an empty set.) r� rm r r r� r r� rg rA )rD rs r� r� ZcsetZnumZi_gcdrG rG rH Z__construct_byset� s zrrule.__construct_bysetc C sL d}xBt d|d �D ]0}t|| j |�\}}||7 }||kr||fS qW dS )a� Calculates the next value in a sequence where the `FREQ` parameter is specified along with a `BYXXX` parameter at the same "level" (e.g. `HOURLY` specified with `BYHOUR`). :param value: The old value of the component. :param byxxx: The `BYXXX` set, which should have been generated by `rrule._construct_byset`, or something else which checks that a valid rule is present. :param base: The largest allowable value for the specified frequency (e.g. 24 hours, 60 minutes). If a valid value is not found after `base` iterations (the maximum number before the sequence would start to repeat), this raises a :exception:`ValueError`, as no valid values were found. This returns a tuple of `divmod(n*interval, base)`, where `n` is the smallest number of `interval` repetitions until the next specified value in `byxxx` is found. r r N)r r r� )rD r� r� r� Z accumulatorr r rG rG rH Z__mod_distance s zrrule.__mod_distance)Nr NNNNNNNNNNNNNF) rI rJ rK rL rC r� r� r` r� r rM rG rG )rF rH r . s t {> /c @ sv e Zd Zddddddddd d d d d ddgZdd� Zdd� Zdd� Zdd� Zdd� Zdd� Z d d � Z d d � Z d d!� Z d"S )#r� r �lastyear� lastmonthr r r � yearweekdayr �mranger r r r r r c C s& x| j D ]}t| |d � qW || _d S )N)� __slots__�setattrr )rD r �attrrG rG rH rC D s z_iterinfo.__init__c C s� | j }|| jk�r2dtj|� | _dtj|d � | _tj|dd�}|j� | _ |j � | _ tj|dd�j � }| jdkr�t | _ t| _t| _t|d � | _t| _n&t| _ t| _t| _t|d � | _t| _|js�d | _�n`dg| jd | _d| j |j d }}|dk�r"d}| j| j |j d }n | j| }t |d�\} } | | d } x�|jD ]�} | dk �rh| | d 7 } d| k �o|| kn �s��qN| dk�r�|| d d } ||k�r�| d| 8 } n|} x8t d�D ],}d| j| < | d7 } | j| |j k�r�P �q�W �qNW d|jk�rr|| d } ||k�r,| d| 8 } | | jk �rrx8t d�D ],}d| j| < | d7 } | j| |j k�rBP �qBW |�r2d|jk�rtj|d dd�j � }d| |j d }dtj|d � }|dk�r�d}d|||j d d d }nd| j| d d }nd}||jk�r2x t |�D ]} d| j| < �q W |j �r�|| j k�sR|| jk�r�g }|j!t"k�r�|j#�r�x:|j#D ]"}|j$| j|d |d � � �qrW n d| jfg}n$|j!t%k�r�| j|d |d � g}|�r�dg| j | _&x�|D ]�\}}|d8 }x�|j D ]�\}} | dk �r8|| d d } | | j| | d 8 } n*|| d d } | d| j| | d 7 } || k�ov|kn �r�d| j&| < �q�W �q�W |j'�r�dg| jd | _(t)j)|�j� | j }x |j'D ]}d| j(|| < �q�W || _|| _ d S ) Nim r r r# r �4 ���r )*r r r� Zisleapr r r� r r� r r r �M365MASKr � MDAY365MASKr � NMDAY365MASKr �WDAYMASKr � M365RANGEr �M366MASK� MDAY366MASK� NMDAY366MASK� M366RANGEr� r r� r r r� r r� r r� rh r r r� r r� )rD r r� �rrZ firstydayr� Zno1wkstZ firstwkstZwyearlenr r ZnumweeksrE rj rl Z lyearweekdayZlno1wkstZlyearlenZ lnumweeksZranges�firstr Zeyday�offsetrG rG rH r� I s� $ z_iterinfo.rebuildc C s t t| j��d| jfS )Nr )rp r r )rD r r� r� rG rG rH r� � s z_iterinfo.ydaysetc C sL d g| j }| j|d |d � \}}xt||�D ] }|||< q2W |||fS )Nr )r r r )rD r r� r� �dsetrs r rj rG rG rH r� � s z_iterinfo.mdaysetc C sl d g| j d }tj|||�j� | j }|}x4td�D ](}|||< |d7 }| j| | jjkr6P q6W |||fS )Nr# r ) r r� r r� r r r r r� )rD r r� r� r+ rj rs rl rG rG rH r� � s z_iterinfo.wdaysetc C s: d g| j }tj|||�j� | j }|||< |||d fS )Nr )r r� r r� r )rD r r� r� r+ rj rG rG rH r� � s z_iterinfo.ddaysetc C sP g }| j }x8|jD ].}x(|jD ] }|jtj||||jd�� q W qW |j� |S )N)r� )r r� r� rh r� r� r� r� )rD r� r� r� �tsetr( rG rG rH r� � s z_iterinfo.htimesetc C s@ g }| j }x(|jD ] }|jtj||||jd�� qW |j� |S )N)r� )r r� rh r� r� r� r� )rD r� r� r� r, r( rG rG rH r � s z_iterinfo.mtimesetc C s t j|||| jjd�fS )N)r� )r� r� r r� )rD r� r� r� rG rG rH r � s z_iterinfo.stimesetN) rI rJ rK r rC r� r� r� r� r� r� r r rG rG rG rH r� > s r� c sj e Zd ZdZG dd� de�Zd� fdd� Zedd� �Zed d � �Z ed d � �Z ed d� �Z dd� Z � Z S )r aL The rruleset type allows more complex recurrence setups, mixing multiple rules, dates, exclusion rules, and exclusion dates.

It accepts all the keywords defined in the RFC as its constructor parameters (except byday, which was renamed to byweekday) and more. The constructor prototype is:: rrule(freq) Where freq must be one of YEARLY, MONTHLY, WEEKLY, DAILY, HOURLY, MINUTELY, or SECONDLY. .. note:: Per RFC section 3.3.10, recurrence instances falling on invalid dates and times are ignored rather than coerced: Recurrence rules may generate recurrence instances with an invalid date (e.g., February 30) or nonexistent local time (e.g., 1:30 AM on a day where the local time is moved forward by an hour at 1:00 AM). Such recurrence instances MUST be ignored and MUST NOT be counted as part of the recurrence set. This can lead to possibly surprising behavior when, for example, the start date occurs at the end of the month: >>> from dateutil.rrule import rrule, MONTHLY >>> from datetime import datetime >>> start_date = datetime(2014, 12, 31) >>> list(rrule(freq=MONTHLY, count=4, dtstart=start_date)) ... # doctest: +NORMALIZE_WHITESPACE [datetime.datetime(2014, 12, 31, 0, 0), datetime.datetime(2015, 1, 31, 0, 0), datetime.datetime(2015, 3, 31, 0, 0), datetime.datetime(2015, 5, 31, 0, 0)] Additionally, it supports the following keyword arguments: :param cache: If given, it must be a boolean value specifying to enable or disable caching of results. If you will use the same rrule instance multiple times, enabling caching will improve the performance considerably. :param dtstart: The recurrence start. Besides being the base for the recurrence, missing parameters in the final recurrence instances will also be extracted from this date. If not given, datetime.now() will be used instead. :param interval: The interval between each freq iteration. For example, when using YEARLY, an interval of 2 means once every two years, but with HOURLY, it means once every two hours. The default interval is 1. :param wkst: The week start day. Must be one of the MO, TU, WE constants, or an integer, specifying the first day of the week. This will affect recurrences based on weekly periods. The default week start is got from calendar.firstweekday(), and may be modified by calendar.setfirstweekday(). :param count: How many occurrences will be generated. .. note:: As of version 2.5.0, the use of the ``until`` keyword together with the ``count`` keyword is deprecated per RFC-2445 Sec. 4.3.10. :param until: If given, this must be a datetime instance, that will specify the limit of the recurrence. The last recurrence in the rule is the greatest datetime that is less than or equal to the value specified in the ``until`` parameter. .. note:: As of version 2.5.0, the use of the ``until`` keyword together with the ``count`` keyword is deprecated per RFC-2445 Sec. 4.3.10. :param bysetpos: If given, it must be either an integer, or a sequence of integers, positive or negative. Each given integer will specify an occurrence number, corresponding to the nth occurrence of the rule inside the frequency period. For example, a bysetpos of -1 if combined with a MONTHLY frequency, and a byweekday of (MO, TU, WE, TH, FR), will result in the last work day of every month. :param bymonth: If given, it must be either an integer, or a sequence of integers, meaning the months to apply the recurrence to. :param bymonthday: If given, it must be either an integer, or a sequence of integers, meaning the month days to apply the recurrence to. :param byyearday: If given, it must be either an integer, or a sequence of integers, meaning the year days to apply the recurrence to. :param byweekno: If given, it must be either an integer, or a sequence of integers, meaning the week numbers to apply the recurrence to. Week numbers have the meaning described in ISO8601, that is, the first week of the year is that containing at least four days of the new year. :param byweekday: If given, it must be either an integer (0 == MO), a sequence of integers, one of the weekday constants (MO, TU, etc), or a sequence of these constants. When given, these variables will define the weekdays where the recurrence will be applied. It's also possible to use an argument n for the weekday instances, which will mean the nth occurrence of this weekday in the period. For example, with MONTHLY, or with YEARLY and BYMONTH, using FR(+1) in byweekday will specify the first friday of the month where the recurrence happens. Notice that in the RFC documentation, this is specified as BYDAY, but was renamed to avoid the ambiguity of that keyword. :param byhour: If given, it must be either an integer, or a sequence of integers, meaning the hours to apply the recurrence to. :param byminute: If given, it must be either an integer, or a sequence of integers, meaning the minutes to apply the recurrence to. :param bysecond: If given, it must be either an integer, or a sequence of integers, meaning the seconds to apply the recurrence to. :param byeaster: If given, it must be either an integer, or a sequence of integers, positive or negative. Each integer will define an offset from the Easter Sunday. Passing the offset 0 to byeaster will yield the Easter Sunday itself. This is an extension to the RFC specification.

This occurs whenever the interval is not coprime with the base of a given unit and the difference between the starting position and the ending position is not coprime with the greatest common denominator between the interval and the base. For example, with a FREQ of hourly starting at 17:00 and an interval of 4, the only valid values for BYHOUR would be {21, 1, 5, 9, 13, 17}, because 4 and 24 are not coprime. :param start: Specifies the starting position. :param byxxx: An iterable containing the list of allowed values. :param base: The largest allowable value for the specified frequency (e.g. 24 hours, 60 minutes). This does not preserve the type of the iterable, returning a set, since the values should be unique and the order is irrelevant, this will speed up later lookups. In the event of an empty set, raises a :exception:`ValueError`, as this results in an empty rrule. r r z+Invalid rrule byxxx generates an empty set.) r� rm r r r� r r� rg rA )rD rs r� r� ZcsetZnumZi_gcdrG rG rH Z__construct_byset� s zrrule.__construct_bysetc C sL d}xBt d|d �D ]0}t|| j |�\}}||7 }||kr||fS qW dS )a� Calculates the next value in a sequence where the `FREQ` parameter is specified along with a `BYXXX` parameter at the same "level" (e.g. `HOURLY` specified with `BYHOUR`). :param value: The old value of the component. :param byxxx: The `BYXXX` set, which should have been generated by `rrule._construct_byset`, or something else which checks that a valid rule is present. :param base: The largest allowable value for the specified frequency (e.g. 24 hours, 60 minutes). If a valid value is not found after `base` iterations (the maximum number before the sequence would start to repeat), this raises a :exception:`ValueError`, as no valid values were found. This returns a tuple of `divmod(n*interval, base)`, where `n` is the smallest number of `interval` repetitions until the next specified value in `byxxx` is found. r r N)r r r� )rD r� r� r� Z accumulatorr r rG rG rH Z__mod_distance s zrrule.__mod_distance)Nr NNNNNNNNNNNNNF) rI rJ rK rL rC r� r� r` r� r rM rG rG )rF rH r . s t {> /c @ sv e Zd Zddddddddd d d d d ddgZdd� Zdd� Zdd� Zdd� Zdd� Zdd� Z d d � Z d d � Z d d!� Z d"S )#r� r �lastyear� lastmonthr r r � yearweekdayr �mranger r r r r r c C s& x| j D ]}t| |d � qW || _d S )N)� __slots__�setattrr )rD r �attrrG rG rH rC D s z_iterinfo.__init__c C s� | j }|| jk�r2dtj|� | _dtj|d � | _tj|dd�}|j� | _ |j � | _ tj|dd�j � }| jdkr�t | _ t| _t| _t|d � | _t| _n&t| _ t| _t| _t|d � | _t| _|js�d | _�n`dg| jd | _d| j |j d }}|dk�r"d}| j| j |j d }n | j| }t |d�\} } | | d } x�|jD ]�} | dk �rh| | d 7 } d| k �o|| kn �s��qN| dk�r�|| d d } ||k�r�| d| 8 } n|} x8t d�D ],}d| j| < | d7 } | j| |j k�r�P �q�W �qNW d|jk�rr|| d } ||k�r,| d| 8 } | | jk �rrx8t d�D ],}d| j| < | d7 } | j| |j k�rBP �qBW |�r2d|jk�rtj|d dd�j � }d| |j d }dtj|d � }|dk�r�d}d|||j d d d }nd| j| d d }nd}||jk�r2x t |�D ]} d| j| < �q W |j �r�|| j k�sR|| jk�r�g }|j!t"k�r�|j#�r�x:|j#D ]"}|j$| j|d |d � � �qrW n d| jfg}n$|j!t%k�r�| j|d |d � g}|�r�dg| j | _&x�|D ]�\}}|d8 }x�|j D ]�\}} | dk �r8|| d d } | | j| | d 8 } n*|| d d } | d| j| | d 7 } || k�ov|kn �r�d| j&| < �q�W �q�W |j'�r�dg| jd | _(t)j)|�j� | j }x |j'D ]}d| j(|| < �q�W || _|| _ d S ) Nim r r r# r �4 ���r )*r r r� Zisleapr r r� r r� r r r �M365MASKr � MDAY365MASKr � NMDAY365MASKr �WDAYMASKr � M365RANGEr �M366MASK� MDAY366MASK� NMDAY366MASK� M366RANGEr� r r� r r r� r r� r r� rh r r r� r r� )rD r r� �rrZ firstydayr� Zno1wkstZ firstwkstZwyearlenr r ZnumweeksrE rj rl Z lyearweekdayZlno1wkstZlyearlenZ lnumweeksZranges�firstr Zeyday�offsetrG rG rH r� I s� $ z_iterinfo.rebuildc C s t t| j��d| jfS )Nr )rp r r )rD r r� r� rG rG rH r� � s z_iterinfo.ydaysetc C sL d g| j }| j|d |d � \}}xt||�D ] }|||< q2W |||fS )Nr )r r r )rD r r� r� �dsetrs r rj rG rG rH r� � s z_iterinfo.mdaysetc C sl d g| j d }tj|||�j� | j }|}x4td�D ](}|||< |d7 }| j| | jjkr6P q6W |||fS )Nr# r ) r r� r r� r r r r r� )rD r r� r� r+ rj rs rl rG rG rH r� � s z_iterinfo.wdaysetc C s: d g| j }tj|||�j� | j }|||< |||d fS )Nr )r r� r r� r )rD r r� r� r+ rj rG rG rH r� � s z_iterinfo.ddaysetc C sP g }| j }x8|jD ].}x(|jD ] }|jtj||||jd�� q W qW |j� |S )N)r� )r r� r� rh r� r� r� r� )rD r� r� r� �tsetr( rG rG rH r� � s z_iterinfo.htimesetc C s@ g }| j }x(|jD ] }|jtj||||jd�� qW |j� |S )N)r� )r r� rh r� r� r� r� )rD r� r� r� r, r( rG rG rH r � s z_iterinfo.mtimesetc C s t j|||| jjd�fS )N)r� )r� r� r r� )rD r� r� r� rG rG rH r � s z_iterinfo.stimesetN) rI rJ rK r rC r� r� r� r� r� r� r r rG rG rG rH r� > s r� c sj e Zd ZdZG dd� de�Zd� fdd� Zedd� �Zed d � �Z ed d � �Z ed d� �Z dd� Z � Z S )r aL The rruleset type allows more complex recurrence setups, mixing multiple rules, dates, exclusion rules, and exclusion dates.

Kenneth Seidelmann, editor. This algorithm implements three different easter calculation methods: 1 - Original calculation in Julian calendar, valid in dates after 326 AD 2 - Original method, with date converted to Gregorian calendar, valid in years 1583 to 4099 3 - Revised method, in Gregorian calendar, valid in years 1583 to 4099 as well These methods are represented by the constants: * ``EASTER_JULIAN = 1`` * ``EASTER_ORTHODOX = 2`` * ``EASTER_WESTERN = 3`` The default method is method 3.

This module attempts to be forgiving with regards to unlikely input formats, returning a datetime object even for dates which are ambiguous. If an element of a date/time stamp is omitted, the following rules are applied: - If AM or PM is left unspecified, a 24-hour clock is assumed, however, an hour on a 12-hour clock (``0 <= hour <= 12``) *must* be specified if AM or PM is specified. - If a time zone is omitted, a timezone-naive datetime is returned. If any other elements are missing, they are taken from the :class:`datetime.datetime` object passed to the parameter ``default``. If this results in a day number exceeding the valid number of days per month, the value falls back to the end of the month. Additional resources about date/time string formats can be found below: - `A summary of the international standard date and time notation <http://www.cl.cam.ac.uk/~mgk25/iso-time.html>`_ - `W3C Date and Time Formats <http://www.w3.org/TR/NOTE-datetime>`_ - `Time Formats (Planetary Rings Node) <http://pds-rings.seti.org/tools/time_formats.html>`_ - `CPAN ParseDate module <http://search.cpan.org/~muir/Time-modules-2013.0912/lib/Time/ParseDate.pm>`_ - `Java SimpleDateFormat Class <https://docs.oracle.com/javase/6/docs/api/java/text/SimpleDateFormat.html>`_ � )�unicode_literalsN)�StringIO)� monthrange)� text_type� binary_type� integer_types� )� relativedelta)�tz�parse� parserinfoc @ sn e Zd Zejd�Zdd� Zdd� Zdd� Zdd � Z d d � Z e d d � �Z e dd� �Z e dd� �Ze dd� �ZdS )�_timelexz([.,])c C sd t |t�r|j� }t |t�r$t|�}t|dd �d krHtdj|jj d���|| _ g | _ g | _ d| _ d S )N�readz8Parser must be a string or character stream, not {itype})ZitypeF)� isinstancer �decoder r �getattr� TypeError�format� __class__�__name__�instream� charstack� tokenstack�eof)�selfr � r � /usr/lib/python3.6/parser.py�__init__4 s z_timelex.__init__c C s� | j r| j jd�S d}d}d}�x�| j�s | jr>| jjd�}n&| jjd�}x|dkrb| jjd�}qLW |srd| _P q"|s�|}| j|�r�d}n$| j|�r�d}n| j|�r�d }P nP q"|dk� r�d}| j|�r�||7 }n$|d kr�||7 }d }n| jj |� P q"|dk�rX| j|��r||7 }n>|d k�s:|d k�rHt |�d k�rH||7 }d}n| jj |� P q"|d k�r�d}|d k�s|| j|��r�||7 }n6| j|��r�|d d k�r�||7 }d}n| jj |� P q"|dkr"|d k�s�| j|��r�||7 }q"| j|��r|d d k�r||7 }d }q"| jj |� P q"W |dk�r�|�sN|j d �dk�sN|d dk�r�| j j |�}|d }x(|dd� D ]}|�rp| j j |� �qpW |dk�r�|j d �dk�r�|jd d �}|S )a� This function breaks the time string into lexical units (tokens), which can be parsed by the parser. Lexical units are demarcated by changes in the character set, so any continuous string of letters is considered one unit, any continuous string of numbers is considered one unit. The main complication arises from the fact that dots ('.') can be used both as separators (e.g. "Sep.20.2009") or decimal points (e.g. "4:30:21.447"). As such, it is necessary to read the full context of any dot-separated strings before breaking it into tokens; as such, this function maintains a "token stack", for when the ambiguous context demands that multiple tokens be parsed at once. r FNr � T�a�0� �.�a.�,� �0.z.,���r' )r# r& r' )r �popr r r r �isword�isnum�isspace�append�len�count�_split_decimal�split�replace)r Z seenletters�token�state�nextchar�l�tokr r r � get_tokenD s� " z_timelex.get_tokenc C s | S )Nr )r r r r �__iter__� s z_timelex.__iter__c C s | j � }|d krt�|S )N)r7 � StopIteration)r r2 r r r �__next__� s z_timelex.__next__c C s | j � S )N)r: )r r r r �next� s z _timelex.nextc C s t | |��S )N)�list)�cls�sr r r r0 � s z_timelex.splitc C s |j � S )z5 Whether or not the next character is part of a word )�isalpha)r= r4 r r r r) � s z_timelex.iswordc C s |j � S )z0 Whether the next character is part of a number )�isdigit)r= r4 r r r r* � s z_timelex.isnumc C s |j � S )z* Whether the next character is whitespace )r+ )r= r4 r r r r+ � s z_timelex.isspaceN)r � __module__� __qualname__�re�compiler/ r r7 r8 r: r; � classmethodr0 r) r* r+ r r r r r 0 s m r c @ s, e Zd Zdd� Zdd� Zdd� Zdd� Zd S ) � _resultbasec C s x| j D ]}t| |d � qW d S )N)� __slots__�setattr)r �attrr r r r � s z_resultbase.__init__c C sN g }x6| j D ],}t| |�}|d k r |jd|t|�f � q W d|dj|�f S )Nz%s=%sz%s(%s)z, )rG r r, �repr�join)r Z classnamer5 rI �valuer r r �_repr� s z_resultbase._reprc s t � fdd�� jD ��S )Nc 3 s | ]}t � |�d k V qd S )N)r )�.0rI )r r r � <genexpr>� s z&_resultbase.__len__.<locals>.<genexpr>)�sumrG )r r )r r �__len__� s z_resultbase.__len__c C s | j | jj�S )N)rM r r )r r r r �__repr__� s z_resultbase.__repr__N)r rA rB r rM rQ rR r r r r rF � s rF c @ s� e Zd ZdZdddddddd d d d d ddddddgZdcdddedfdgdhdigZdjdkdldmdndodpdqdrdsdtdug ZdvdwdxgZdydzgZdFdGdHgZ dgZ i Z d{dJdK�Z dLdM� Z dNdO� ZdPdQ� ZdRdS� ZdTdU� ZdVdW� ZdXdY� ZdZd[� Zd\d]� Zd|d^d_�Zd`da� ZdbS )}r a� Class which handles what inputs are accepted.

Lemburg in his `mx.DateTime <http://www.egenix.com/files/python/mxDateTime.html>`_ extension. However, notice that this type does *NOT* implement the same algorithm as his work. Do *NOT* expect it to behave like mx.DateTime's counterpart. There are two different ways to build a relativedelta instance. The first one is passing it two date/datetime classes:: relativedelta(datetime1, datetime2) The second one is passing it any number of the following keyword arguments:: relativedelta(arg1=x,arg2=y,arg3=z...) year, month, day, hour, minute, second, microsecond: Absolute information (argument is singular); adding or subtracting a relativedelta with absolute information does not perform an aritmetic operation, but rather REPLACES the corresponding value in the original datetime with the value(s) in relativedelta. years, months, weeks, days, hours, minutes, seconds, microseconds: Relative information, may be negative (argument is plural); adding or subtracting a relativedelta with relative information performs the corresponding aritmetic operation on the original datetime value with the information in the relativedelta. weekday: One of the weekday instances (MO, TU, etc). These instances may receive a parameter N, specifying the Nth weekday, which could be positive or negative (like MO(+1) or MO(-2). Not specifying it is the same as specifying +1. You can also use an integer, where 0=MO. leapdays: Will add given days to the date found, if year is a leap year, and the date found is post 28 of february. yearday, nlyearday: Set the yearday or the non-leap year day (jump leap days). These are converted to day/month/leapdays information. Here is the behavior of operations with relativedelta: 1. Calculate the absolute year, using the 'year' argument, or the original datetime year, if the argument is not present. 2. Add the relative 'years' argument to the absolute year. 3. Do steps 1 and 2 for month/months. 4. Calculate the absolute day, using the 'day' argument, or the original datetime day, if the argument is not present. Then, subtract from the day until it fits in the year and month found after their operations. 5. Add the relative 'days' argument to the absolute day. Notice that the 'weeks' argument is multiplied by 7 and added to 'days'. 6. Do steps 1 and 2 for hour/hours, minute/minutes, second/seconds, microsecond/microseconds. 7. If the 'weekday' argument is present, calculate the weekday, with the given (wday, nth) tuple. wday is the index of the weekday (0-6, 0=Mon), and nth is the number of weeks to add forward or backward, depending on its signal. Notice that if the calculated date is already Monday, for example, using (0, 1) or (0, -1) won't change the day.

It accepts all the keywords defined in the RFC as its constructor parameters (except byday, which was renamed to byweekday) and more. The constructor prototype is:: rrule(freq) Where freq must be one of YEARLY, MONTHLY, WEEKLY, DAILY, HOURLY, MINUTELY, or SECONDLY. .. note:: Per RFC section 3.3.10, recurrence instances falling on invalid dates and times are ignored rather than coerced: Recurrence rules may generate recurrence instances with an invalid date (e.g., February 30) or nonexistent local time (e.g., 1:30 AM on a day where the local time is moved forward by an hour at 1:00 AM). Such recurrence instances MUST be ignored and MUST NOT be counted as part of the recurrence set. This can lead to possibly surprising behavior when, for example, the start date occurs at the end of the month: >>> from dateutil.rrule import rrule, MONTHLY >>> from datetime import datetime >>> start_date = datetime(2014, 12, 31) >>> list(rrule(freq=MONTHLY, count=4, dtstart=start_date)) ... # doctest: +NORMALIZE_WHITESPACE [datetime.datetime(2014, 12, 31, 0, 0), datetime.datetime(2015, 1, 31, 0, 0), datetime.datetime(2015, 3, 31, 0, 0), datetime.datetime(2015, 5, 31, 0, 0)] Additionally, it supports the following keyword arguments: :param cache: If given, it must be a boolean value specifying to enable or disable caching of results. If you will use the same rrule instance multiple times, enabling caching will improve the performance considerably. :param dtstart: The recurrence start. Besides being the base for the recurrence, missing parameters in the final recurrence instances will also be extracted from this date. If not given, datetime.now() will be used instead. :param interval: The interval between each freq iteration. For example, when using YEARLY, an interval of 2 means once every two years, but with HOURLY, it means once every two hours. The default interval is 1. :param wkst: The week start day. Must be one of the MO, TU, WE constants, or an integer, specifying the first day of the week. This will affect recurrences based on weekly periods. The default week start is got from calendar.firstweekday(), and may be modified by calendar.setfirstweekday(). :param count: How many occurrences will be generated. .. note:: As of version 2.5.0, the use of the ``until`` keyword together with the ``count`` keyword is deprecated per RFC-2445 Sec. 4.3.10. :param until: If given, this must be a datetime instance, that will specify the limit of the recurrence. The last recurrence in the rule is the greatest datetime that is less than or equal to the value specified in the ``until`` parameter. .. note:: As of version 2.5.0, the use of the ``until`` keyword together with the ``count`` keyword is deprecated per RFC-2445 Sec. 4.3.10. :param bysetpos: If given, it must be either an integer, or a sequence of integers, positive or negative. Each given integer will specify an occurrence number, corresponding to the nth occurrence of the rule inside the frequency period. For example, a bysetpos of -1 if combined with a MONTHLY frequency, and a byweekday of (MO, TU, WE, TH, FR), will result in the last work day of every month. :param bymonth: If given, it must be either an integer, or a sequence of integers, meaning the months to apply the recurrence to. :param bymonthday: If given, it must be either an integer, or a sequence of integers, meaning the month days to apply the recurrence to. :param byyearday: If given, it must be either an integer, or a sequence of integers, meaning the year days to apply the recurrence to. :param byweekno: If given, it must be either an integer, or a sequence of integers, meaning the week numbers to apply the recurrence to. Week numbers have the meaning described in ISO8601, that is, the first week of the year is that containing at least four days of the new year. :param byweekday: If given, it must be either an integer (0 == MO), a sequence of integers, one of the weekday constants (MO, TU, etc), or a sequence of these constants. When given, these variables will define the weekdays where the recurrence will be applied. It's also possible to use an argument n for the weekday instances, which will mean the nth occurrence of this weekday in the period. For example, with MONTHLY, or with YEARLY and BYMONTH, using FR(+1) in byweekday will specify the first friday of the month where the recurrence happens. Notice that in the RFC documentation, this is specified as BYDAY, but was renamed to avoid the ambiguity of that keyword. :param byhour: If given, it must be either an integer, or a sequence of integers, meaning the hours to apply the recurrence to. :param byminute: If given, it must be either an integer, or a sequence of integers, meaning the minutes to apply the recurrence to. :param bysecond: If given, it must be either an integer, or a sequence of integers, meaning the seconds to apply the recurrence to. :param byeaster: If given, it must be either an integer, or a sequence of integers, positive or negative. Each integer will define an offset from the Easter Sunday. Passing the offset 0 to byeaster will yield the Easter Sunday itself. This is an extension to the RFC specification.

Do *NOT* expect it to behave like mx.DateTime's counterpart. There are two different ways to build a relativedelta instance. The first one is passing it two date/datetime classes:: relativedelta(datetime1, datetime2) The second one is passing it any number of the following keyword arguments:: relativedelta(arg1=x,arg2=y,arg3=z...) year, month, day, hour, minute, second, microsecond: Absolute information (argument is singular); adding or subtracting a relativedelta with absolute information does not perform an aritmetic operation, but rather REPLACES the corresponding value in the original datetime with the value(s) in relativedelta. years, months, weeks, days, hours, minutes, seconds, microseconds: Relative information, may be negative (argument is plural); adding or subtracting a relativedelta with relative information performs the corresponding aritmetic operation on the original datetime value with the information in the relativedelta. weekday: One of the weekday instances (MO, TU, etc). These instances may receive a parameter N, specifying the Nth weekday, which could be positive or negative (like MO(+1) or MO(-2). Not specifying it is the same as specifying +1. You can also use an integer, where 0=MO. leapdays: Will add given days to the date found, if year is a leap year, and the date found is post 28 of february. yearday, nlyearday: Set the yearday or the non-leap year day (jump leap days). These are converted to day/month/leapdays information. Here is the behavior of operations with relativedelta: 1. Calculate the absolute year, using the 'year' argument, or the original datetime year, if the argument is not present. 2. Add the relative 'years' argument to the absolute year. 3. Do steps 1 and 2 for month/months. 4. Calculate the absolute day, using the 'day' argument, or the original datetime day, if the argument is not present. Then, subtract from the day until it fits in the year and month found after their operations. 5. Add the relative 'days' argument to the absolute day. Notice that the 'weeks' argument is multiplied by 7 and added to 'days'. 6. Do steps 1 and 2 for hour/hours, minute/minutes, second/seconds, microsecond/microseconds. 7. If the 'weekday' argument is present, calculate the weekday, with the given (wday, nth) tuple. wday is the index of the weekday (0-6, 0=Mon), and nth is the number of weeks to add forward or backward, depending on its signal. Notice that if the calculated date is already Monday, for example, using (0, 1) or (0, -1) won't change the day.

Use :func:`get_zonefile_instance` to retrieve an instance of the dateutil-provided zoneinfo. z�zoneinfo.gettz() will be removed in future versions, to use the dateutil-provided zoneinfo files, instantiate a ZoneInfoFile object and use ZoneInfoFile.zones.get() instead.

This module attempts to be forgiving with regards to unlikely input formats, returning a datetime object even for dates which are ambiguous. If an element of a date/time stamp is omitted, the following rules are applied: - If AM or PM is left unspecified, a 24-hour clock is assumed, however, an hour on a 12-hour clock (``0 <= hour <= 12``) *must* be specified if AM or PM is specified. - If a time zone is omitted, a timezone-naive datetime is returned. If any other elements are missing, they are taken from the :class:`datetime.datetime` object passed to the parameter ``default``. If this results in a day number exceeding the valid number of days per month, the value falls back to the end of the month.
