+.Synopsis
+Activate a Python virtual environment for the current PowerShell session.
+
+.Description
+Pushes the python executable for a virtual environment to the front of the
+$Env:PATH environment variable and sets the prompt to signify that you are
+in a Python virtual environment. Makes use of the command line switches as
+well as the `pyvenv.cfg` file values present in the virtual environment.
+
+.Parameter VenvDir
+Path to the directory that contains the virtual environment to activate. The
+default value for this is the parent of the directory that the Activate.ps1
+script is located within.
+
+.Parameter Prompt
+The prompt prefix to display when this virtual environment is activated. By
+default, this prompt is the name of the virtual environment folder (VenvDir)
+surrounded by parentheses and followed by a single space (ie. '(.venv) ').
+
+.Example
+Activate.ps1
+Activates the Python virtual environment that contains the Activate.ps1 script.
+
+.Example
+Activate.ps1 -Verbose
+Activates the Python virtual environment that contains the Activate.ps1 script,
+and shows extra information about the activation as it executes.
+
+.Example
+Activate.ps1 -VenvDir C:\Users\MyUser\Common\.venv
+Activates the Python virtual environment located in the specified location.
+
+.Example
+Activate.ps1 -Prompt "MyPython"
+Activates the Python virtual environment that contains the Activate.ps1 script,
+and prefixes the current prompt with the specified string (surrounded in
+parentheses) while the virtual environment is active.
+
+.Notes
+On Windows, it may be required to enable this Activate.ps1 script by setting the
+execution policy for the user. You can do this by issuing the following PowerShell
+command:
+
+PS C:\> Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
+
+For more information on Execution Policies:

+Jinja
+=====
+
+Jinja is a fast, expressive, extensible templating engine. Special
+placeholders in the template allow writing code similar to Python
+syntax. Then the template is passed data to render the final document.
+
+It includes:
+
+- Template inheritance and inclusion.
+- Define and import macros within templates.
+- HTML templates can use autoescaping to prevent XSS from untrusted
+ user input.
+- A sandboxed environment can safely render untrusted templates.
+- AsyncIO support for generating templates and calling async
+ functions.
+- I18N support with Babel.
+- Templates are compiled to optimized Python code just-in-time and
+ cached, or can be compiled ahead-of-time.
+- Exceptions point to the correct line in templates to make debugging
+ easier.
+- Extensible filters, tests, functions, and even syntax.
+
+Jinja's philosophy is that while application logic belongs in Python if
+possible, it shouldn't make the template designer's job difficult by
+restricting functionality too much.
+
+

+MarkupSafe
+==========
+
+MarkupSafe implements a text object that escapes characters so it is
+safe to use in HTML and XML. Characters that have special meanings are
+replaced so that they display as the actual characters. This mitigates
+injection attacks, meaning untrusted user input can safely be displayed
+on a page.
+
+
+Installing
+----------
+
+Install and update using `pip`_:
+
+.. code-block:: text
+
+ pip install -U MarkupSafe
+
+.. _pip: https://pip.pypa.io/en/stable/getting-started/
+
+
+Examples
+--------
+
+.. code-block:: pycon
+
+ >>> from markupsafe import Markup, escape
+
+ >>> # escape replaces special characters and wraps in Markup
+ >>> escape("<script>alert(document.cookie);</script>")
+ Markup('<script>alert(document.cookie);</script>')
+
+ >>> # wrap in Markup to mark text "safe" and prevent escaping
+ >>> Markup("<strong>Hello</strong>")
+ Markup('<strong>hello</strong>')
+
+ >>> escape(Markup("<strong>Hello</strong>"))
+ Markup('<strong>hello</strong>')
+
+ >>> # Markup is a str subclass
+ >>> # methods and operators escape their arguments
+ >>> template = Markup("Hello <em>{name}</em>")
+ >>> template.format(name='"World"')
+ Markup('Hello <em>"World"</em>')

+==========
+
+Click is a Python package for creating beautiful command line interfaces
+in a composable way with as little code as necessary. It's the "Command
+Line Interface Creation Kit". It's highly configurable but comes with
+sensible defaults out of the box.
+
+It aims to make the process of writing command line tools quick and fun
+while also preventing any frustration caused by the inability to
+implement an intended CLI API.
+
+Click in three points:
+
+- Arbitrary nesting of commands
+- Automatic help page generation
+- Supports lazy loading of subcommands at runtime
+
+
+Installing
+----------
+
+Install and update using `pip`_:
+
+.. code-block:: text
+
+ $ pip install -U click
+
+.. _pip: https://pip.pypa.io/en/stable/getting-started/
+
+
+A Simple Example
+----------------
+
+.. code-block:: python
+
+ import click
+
+ @click.command()
+ @click.option("--count", default=1, help="Number of greetings.")
+ @click.option("--name", prompt="Your name", help="The person to greet.")
+ def hello(count, name):
+ """Simple program that greets NAME for a total of COUNT times."""
+ for _ in range(count):
+ click.echo(f"Hello, {name}!")
+
+ if __name__ == '__main__':
+ hello()
+
+.. code-block:: text
+
+ $ python hello.py --count=3
+ Your name: Click
+ Hello, Click!

+ the default help parameter is named. The
+ default is ``['--help']``.
+ :param token_normalize_func: an optional function that is used to
+ normalize tokens (options, choices,
+ etc.). This for instance can be used to
+ implement case insensitive behavior.
+ :param color: controls if the terminal supports ANSI colors or not. The
+ default is autodetection. This is only needed if ANSI
+ codes are used in texts that Click prints which is by
+ default not the case. This for instance would affect
+ help output.

+This module started out as largely a copy paste from the stdlib's
+optparse module with the features removed that we do not need from
+optparse because we implement them in Click on a higher level (for
+instance type handling, help formatting and a lot more).
+
+The plan is to remove more and more from here over time.
+
+The reason this is a different module and not optparse from the stdlib
+is that there are differences in 2.x and 3.x about the error messages
+generated and optparse in the stdlib uses gettext for no good reason
+and might cause us issues.
+
+Click uses parts of optparse written by Gregory P. Ward and maintained
+by the Python Software Foundation. This is limited to code in parser.py.

+ """This function creates an iterable context manager that can be used
+ to iterate over something while showing a progress bar. It will
+ either iterate over the `iterable` or `length` items (that are counted
+ up). While iteration happens, this function will print a rendered
+ progress bar to the given `file` (defaults to stdout) and will attempt
+ to calculate remaining time and more. By default, this progress bar
+ will not be rendered if the file is not a terminal.
+
+ The context manager creates the progress bar. When the context
+ manager is entered the progress bar is already created. With every
+ iteration over the progress bar, the iterable passed to the bar is
+ advanced and the bar is updated. When the context manager exits,
+ a newline is printed and the progress bar is finalized on screen.
+
+ Note: The progress bar is currently designed for use cases where the
+ total progress can be expected to take at least several seconds.
+ Because of this, the ProgressBar class object won't display
+ progress that is considered too fast, and progress where the time
+ between steps is less than a second.
+
+ No printing must happen or the progress bar will be unintentionally
+ destroyed.
+
+ Example usage::
+
+ with progressbar(items) as bar:
+ for item in bar:
+ do_something_with(item)
+
+ Alternatively, if no iterable is specified, one can manually update the
+ progress bar through the `update()` method instead of directly
+ iterating over the progress bar. The update method accepts the number
+ of steps to increment the bar with::
+
+ with progressbar(length=chunks.total_bytes) as bar:
+ for chunk in chunks:
+ process_chunk(chunk)
+ bar.update(chunks.bytes)
+
+ The ``update()`` method also takes an optional value specifying the
+ ``current_item`` at the new position. This is useful when used
+ together with ``item_show_func`` to customize the output for each
+ manual step::
+
+ with click.progressbar(
+ length=total_size,
+ label='Unzipping archive',
+ item_show_func=lambda a: a.filename
+ ) as bar:
+ for archive in zip_file:
+ archive.extract()
+ bar.update(archive.size, archive)
+
+ :param iterable: an iterable to iterate over. If not provided the length
+ is required.
+ :param length: the number of items to iterate over. By default the
+ progressbar will attempt to ask the iterator about its
+ length, which might or might not work. If an iterable is
+ also provided this parameter can be used to override the
+ length. If an iterable is not provided the progress bar
+ will iterate over a range of that length.
+ :param label: the label to show next to the progress bar.
+ :param show_eta: enables or disables the estimated time display. This is
+ automatically disabled if the length cannot be
+ determined.
+ :param show_percent: enables or disables the percentage display. The
+ default is `True` if the iterable has a length or
+ `False` if not.
+ :param show_pos: enables or disables the absolute position display. The
+ default is `False`.
+ :param item_show_func: A function called with the current item which
+ can return a string to show next to the progress bar. If the
+ function returns ``None`` nothing is shown. The current item can
+ be ``None``, such as when entering and exiting the bar.
+ :param fill_char: the character to use to show the filled part of the
+ progress bar.
+ :param empty_char: the character to use to show the non-filled part of
+ the progress bar.
+ :param bar_template: the format string to use as template for the bar.
+ The parameters in it are ``label`` for the label,
+ ``bar`` for the progress bar and ``info`` for the
+ info section.
+ :param info_sep: the separator between multiple info items (eta etc.)
+ :param width: the width of the progress bar in characters, 0 means full
+ terminal width
+ :param file: The file to write to. If this is not a terminal then
+ only the label is printed.
+ :param color: controls if the terminal supports ANSI colors or not. The
+ default is autodetection. This is only needed if ANSI
+ codes are included anywhere in the progress bar output
+ which is not the case by default.
+ :param update_min_steps: Render only when this many updates have
+ completed. This allows tuning for very fast iterators.

+ the underlying cache client to the bytecode cache which is available
+ as `django.core.cache.cache._client`.)
+
+ The minimal interface for the client passed to the constructor is this:
+
+ .. class:: MinimalClientInterface
+
+ .. method:: set(key, value[, timeout])
+
+ Stores the bytecode in the cache. `value` is a string and
+ `timeout` the timeout of the key. If timeout is not provided
+ a default timeout or no timeout should be assumed, if it's
+ provided it's an integer with the number of seconds the cache
+ item should exist.
+
+ .. method:: get(key)
+
+ Returns the value for the cache key. If the item does not
+ exist in the cache the return value must be `None`.
+
+ The other arguments to the constructor are the prefix for all keys that
+ is added before the actual cache key and the timeout for the bytecode in
+ the cache system. We recommend a high (or no) timeout.
+
+ This bytecode cache does not support clearing of used items in the cache.

+ Modifications on environments after the first template was loaded
+ will lead to surprising effects and undefined behavior.
+
+ Here are the possible initialization parameters:
+
+ `block_start_string`
+ The string marking the beginning of a block. Defaults to ``'{%'``.
+
+ `block_end_string`
+ The string marking the end of a block. Defaults to ``'%}'``.
+
+ `variable_start_string`
+ The string marking the beginning of a print statement.
+ Defaults to ``'{{'``.
+
+ `variable_end_string`
+ The string marking the end of a print statement. Defaults to
+ ``'}}'``.
+
+ `comment_start_string`
+ The string marking the beginning of a comment. Defaults to ``'{#'``.
+
+ `comment_end_string`
+ The string marking the end of a comment. Defaults to ``'#}'``.
+
+ `line_statement_prefix`
+ If given and a string, this will be used as prefix for line based
+ statements. See also :ref:`line-statements`.
+
+ `line_comment_prefix`
+ If given and a string, this will be used as prefix for line based
+ comments. See also :ref:`line-statements`.
+
+ .. versionadded:: 2.2
+
+ `trim_blocks`
+ If this is set to ``True`` the first newline after a block is
+ removed (block, not variable tag!). Defaults to `False`.
+
+ `lstrip_blocks`
+ If this is set to ``True`` leading spaces and tabs are stripped
+ from the start of a line to a block. Defaults to `False`.
+
+ `newline_sequence`
+ The sequence that starts a newline. Must be one of ``'\r'``,
+ ``'\n'`` or ``'\r\n'``. The default is ``'\n'`` which is a
+ useful default for Linux and OS X systems as well as web
+ applications.
+
+ `keep_trailing_newline`
+ Preserve the trailing newline when rendering templates.
+ The default is ``False``, which causes a single newline,
+ if present, to be stripped from the end of the template.
+
+ .. versionadded:: 2.7
+
+ `extensions`
+ List of Jinja extensions to use. This can either be import paths
+ as strings or extension classes. For more information have a
+ look at :ref:`the extensions documentation <jinja-extensions>`.
+
+ `optimized`
+ should the optimizer be enabled? Default is ``True``.
+
+ `undefined`
+ :class:`Undefined` or a subclass of it that is used to represent
+ undefined values in the template.
+
+ `finalize`
+ A callable that can be used to process the result of a variable
+ expression before it is output. For example one can convert
+ ``None`` implicitly into an empty string here.
+
+ `autoescape`
+ If set to ``True`` the XML/HTML autoescaping feature is enabled by
+ default. For more details about autoescaping see
+ :class:`~markupsafe.Markup`. As of Jinja 2.4 this can also
+ be a callable that is passed the template name and has to
+ return ``True`` or ``False`` depending on autoescape should be
+ enabled by default.
+
+ .. versionchanged:: 2.4
+ `autoescape` can now be a function
+
+ `loader`
+ The template loader for this environment.
+
+ `cache_size`
+ The size of the cache. Per default this is ``400`` which means
+ that if more than 400 templates are loaded the loader will clean
+ out the least recently used template. If the cache size is set to
+ ``0`` templates are recompiled all the time, if the cache size is
+ ``-1`` the cache will not be cleaned.
+
+ .. versionchanged:: 2.8
+ The cache size was increased to 400 from a low 50.
+
+ `auto_reload`
+ Some loaders load templates from locations where the template
+ sources may change (ie: file system or database). If
+ ``auto_reload`` is set to ``True`` (default) every time a template is
+ requested the loader checks if the source changed and if yes, it
+ will reload the template. For higher performance it's possible to
+ disable that.
+
+ `bytecode_cache`
+ If set to a bytecode cache object, this object will provide a
+ cache for the internal Jinja bytecode so that templates don't
+ have to be parsed if they were not changed.
+
+ See :ref:`bytecode-cache` for more information.
+
+ `enable_async`
+ If set to true this enables async template execution which
+ allows using async functions and generators.

+ the values are sorted first so only one group is returned for each
+ unique value.
+
+ For example, a list of ``User`` objects with a ``city`` attribute

+
+ ``groupby`` yields namedtuples of ``(grouper, list)``, which

+
+ .. sourcecode:: html+jinja
+
+ <ul>{% for group in users|groupby("city") %}
+ <li>{{ group.grouper }}: {{ group.list|join(", ") }}

+ <ul>{% for city, items in users|groupby("city", default="NY") %}
+ <li>{{ city }}: {{ items|map(attribute="name")|join(", ") }}</li>
+ {% endfor %}</ul>
+
+ Like the :func:`~jinja-filters.sort` filter, sorting and grouping is
+ case-insensitive by default. The ``key`` for each group will have
+ the case of the first item in that group of values. For example, if

+
+pip is the `package installer`_ for Python. You can use pip to install packages from the `Python Package Index`_ and other indexes.
+
+Please take a look at our documentation for how to install and use pip:
+
+* `Installation`_
+* `Usage`_
+
+We release updates regularly, with a new version every 3 months. Find more details in our documentation:
+
+* `Release notes`_
+* `Release process`_
+
+In pip 20.3, we've `made a big improvement to the heart of pip`_; `learn more`_. We want your input, so `sign up for our user experience research studies`_ to help us do it right.
+
+**Note**: pip 21.0, in January 2021, removed Python 2 support, per pip's `Python 2 support policy`_. Please migrate to Python 3.
+
+If you find bugs, need help, or want to talk to the developers, please use our mailing lists or chat rooms:
+
+* `Issue tracking`_
+* `Discourse channel`_
+* `User IRC`_
+
+If you want to get involved head over to GitHub to get the source code, look at our development documentation and feel free to jump on the developer mailing lists and chat rooms:
+
+* `GitHub page`_
+* `Development documentation`_
+* `Development IRC`_
+
+Code of Conduct

+shared options and groups
+
+The principle here is to define options once, but *not* instantiate them
+globally. One reason being that options with action='append' can carry state
+between parses. pip parses general options twice internally, and shouldn't
+pass on state. To be consistent, all options will follow this design.

+ # In the meantime, projects using versioned entry points will either have

+ candidate will provide it, and we don't want to end up with duplicates.

+ The dependency on the base candidate is needed so that the resolver can't

+
+# This prober doesn't actually recognize a language or a charset.
+# It is a helper prober for the use of the Hebrew model probers
+
+### General ideas of the Hebrew charset recognition ###
+#
+# Four main charsets exist in Hebrew:
+# "ISO-8859-8" - Visual Hebrew
+# "windows-1255" - Logical Hebrew
+# "ISO-8859-8-I" - Logical Hebrew
+# "x-mac-hebrew" - ?? 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. The answer is returned in the form of the name of the
+# charset identified, either "windows-1255" or "ISO-8859-8".

+The ``distro`` package (``distro`` stands for Linux Distribution) provides
+information about the Linux distribution it runs on, such as a reliable
+machine-readable distro ID, or version information.
+
+It is the recommended replacement for Python's original
+:py:func:`platform.linux_distribution` function, but it provides much more
+functionality. An alternative implementation became necessary because Python
+3.5 deprecated this function, and Python 3.8 removed it altogether. Its
+predecessor function :py:func:`platform.dist` was already deprecated since
+Python 2.6 and removed in Python 3.8. Still, there are many cases in which
+access to OS distribution information is needed. See `Python issue 1322
+<https://bugs.python.org/issue1322>`_ for more information.

+ MessagePack Packer
+
+ Usage::
+
+ packer = Packer()
+ astream.write(packer.pack(a))
+ astream.write(packer.pack(b))
+
+ Packer's constructor has some keyword arguments:
+
+ :param callable default:
+ Convert user type to builtin type that Packer supports.
+ See also simplejson's document.
+
+ :param bool use_single_float:
+ Use single precision float type for float. (default: False)
+
+ :param bool autoreset:
+ Reset buffer after each pack and return its content as `bytes`. (default: True).
+ If set this to false, use `bytes()` to get content and `.reset()` to clear buffer.
+
+ :param bool use_bin_type:
+ Use bin type introduced in msgpack spec 2.0 for bytes.
+ It also enables str8 type for unicode. (default: True)
+
+ :param bool strict_types:
+ If set to true, types will be checked to be exact. Derived classes
+ from serializable types will not be serialized and will be
+ treated as unsupported type and forwarded to default.
+ Additionally tuples will not be serialized as lists.
+ This is useful when trying to implement accurate serialization
+ for python types.
+
+ :param bool datetime:
+ If set to true, datetime with tzinfo is packed into Timestamp type.
+ Note that the tzinfo is stripped in the timestamp.
+ You can get UTC datetime with `timestamp=3` option of the Unpacker.
+ (Python 2 is not supported).
+
+ :param str unicode_errors:
+ The error handler for encoding unicode. (default: 'strict')
+ DO NOT USE THIS!! This option is kept for very specific usage.
+
+ Example of streaming deserialize from file-like object::
+
+ unpacker = Unpacker(file_like)
+ for o in unpacker:
+ process(o)
+
+ Example of streaming deserialize from socket::
+
+ unpacker = Unpacker()
+ while True:
+ buf = sock.recv(1024**2)
+ if not buf:
+ break
+ unpacker.feed(buf)
+ for o in unpacker:
+ process(o)
+
+ Raises ``ExtraData`` when *packed* contains extra bytes.
+ Raises ``OutOfData`` when *packed* is incomplete.
+ Raises ``FormatError`` when *packed* is not valid msgpack.
+ Raises ``StackError`` when *packed* contains too nested.
+ Other exceptions can be raised during unpacking.

+Package resource API
+--------------------
+
+A resource is a logical file contained within a package, or a logical
+subdirectory thereof. 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.

+ Pygments
+ ~~~~~~~~
+
+ Pygments is a syntax highlighting package written in Python.
+
+ It is a generic syntax highlighter for general use in all kinds of software
+ such as forum systems, wikis or other applications that need to prettify
+ source code. Highlights are:
+
+ * a wide range of common languages and markup formats is supported
+ * special attention is paid to details, increasing quality by a fair amount
+ * support for new languages and formats are added easily
+ * a number of output formats, presently HTML, LaTeX, RTF, SVG, all image
+ formats that PIL supports, and ANSI sequences
+ * it is usable as a command-line tool and as a library
+ * ... and it highlights even Brainfuck!
+
+ The `Pygments master branch`_ is installable with ``easy_install Pygments==dev``.

+ A list of lines can be specified using the `hl_lines` option to make these
+ lines highlighted (as of Pygments 0.11).
+
+ With the `full` option, a complete HTML 4 document is output, including
+ the style definitions inside a ``<style>`` tag, or in a separate file if
+ the `cssfile` option is given.
+
+ When `tagsfile` is set to the path of a ctags index file, it is used to
+ generate hyperlinks from names to their definition. You must enable
+ `lineanchors` and run ctags with the `-n` option for this to work. The
+ `python-ctags` module from PyPI must be installed to use this feature;
+ otherwise a `RuntimeError` will be raised.
+
+ The `get_style_defs(arg='')` method of a `HtmlFormatter` returns a string
+ containing CSS rules for the CSS classes used by the formatter. The
+ argument `arg` can be used to specify additional CSS selectors that
+ are prepended to the classes. A call `fmter.get_style_defs('td .code')`
+ would result in the following CSS classes:
+
+ .. sourcecode:: css
+
+ td .code .kw { font-weight: bold; color: #00FF00 }
+ td .code .cm { color: #999999 }
+ ...
+
+ If you have Pygments 0.6 or higher, you can also pass a list or tuple to the
+ `get_style_defs()` method to request multiple prefixes for the tokens:
+
+ .. sourcecode:: python
+
+ formatter.get_style_defs(['div.syntax pre', 'pre.syntax'])
+
+ The output would then look like this:
+
+ .. sourcecode:: css
+
+ div.syntax pre .kw,
+ pre.syntax .kw { font-weight: bold; color: #00FF00 }
+ div.syntax pre .cm,
+ pre.syntax .cm { color: #999999 }
+ ...
+
+ Additional options accepted:
+
+ `nowrap`
+ If set to ``True``, don't wrap the tokens at all, not even inside a ``<pre>``
+ tag. This disables most other options (default: ``False``).
+
+ `full`
+ Tells the formatter to output a "full" document, i.e. a complete
+ self-contained document (default: ``False``).
+
+ `title`
+ If `full` is true, the title that should be used to caption the
+ document (default: ``''``).
+
+ `style`
+ The style to use, can be a string or a Style subclass (default:
+ ``'default'``). This option has no effect if the `cssfile`
+ and `noclobber_cssfile` option are given and the file specified in
+ `cssfile` exists.
+
+ `noclasses`
+ If set to true, token ``<span>`` tags (as well as line number elements)
+ will not use CSS classes, but inline styles. This is not recommended
+ for larger pieces of code since it increases output size by quite a bit
+ (default: ``False``).
+
+ `classprefix`
+ Since the token types use relatively short class names, they may clash
+ with some of your own class names. In this case you can use the
+ `classprefix` option to give a string to prepend to all Pygments-generated
+ CSS class names for token types.
+ Note that this option also affects the output of `get_style_defs()`.
+
+ `cssclass`
+ CSS class for the wrapping ``<div>`` tag (default: ``'highlight'``).
+ If you set this option, the default selector for `get_style_defs()`
+ will be this class.
+
+ .. versionadded:: 0.9
+ If you select the ``'table'`` line numbers, the wrapping table will
+ have a CSS class of this string plus ``'table'``, the default is
+ accordingly ``'highlighttable'``.
+
+ `cssstyles`
+ Inline CSS styles for the wrapping ``<div>`` tag (default: ``''``).
+
+ `prestyles`
+ Inline CSS styles for the ``<pre>`` tag (default: ``''``).
+
+ .. versionadded:: 0.11
+
+ `cssfile`
+ If the `full` option is true and this option is given, it must be the
+ name of an external file. If the filename does not include an absolute
+ path, the file's path will be assumed to be relative to the main output
+ file's path, if the latter can be found. The stylesheet is then written
+ to this file instead of the HTML file.
+
+ .. versionadded:: 0.6
+
+ `noclobber_cssfile`
+ If `cssfile` is given and the specified file exists, the css file will
+ not be overwritten. This allows the use of the `full` option in
+ combination with a user specified css file. Default is ``False``.
+
+ .. versionadded:: 1.1
+
+ `linenos`
+ If set to ``'table'``, output line numbers as a table with two cells,
+ one containing the line numbers, the other the whole code. This is
+ copy-and-paste-friendly, but may cause alignment problems with some
+ browsers or fonts. If set to ``'inline'``, the line numbers will be
+ integrated in the ``<pre>`` tag that contains the code (that setting
+ is *new in Pygments 0.8*).
+
+ For compatibility with Pygments 0.7 and earlier, every true value
+ except ``'inline'`` means the same as ``'table'`` (in particular, that
+ means also ``True``).
+
+ The default value is ``False``, which means no line numbers at all.
+
+ **Note:** with the default ("table") line number mechanism, the line
+ numbers and code can have different line heights in Internet Explorer
+ unless you give the enclosing ``<pre>`` tags an explicit ``line-height``
+ CSS property (you get the default line spacing with ``line-height:
+ 125%``).
+
+ `hl_lines`
+ Specify a list of lines to be highlighted. The line numbers are always
+ relative to the input (i.e. the first line is line 1) and are
+ independent of `linenostart`.
+
+ .. versionadded:: 0.11
+
+ `linenostart`
+ The line number for the first line (default: ``1``).
+
+ `linenostep`
+ If set to a number n > 1, only every nth line number is printed.
+
+ `linenospecial`
+ If set to a number n > 0, every nth line number is given the CSS
+ class ``"special"`` (default: ``0``).
+
+ `nobackground`
+ If set to ``True``, the formatter won't output the background color
+ for the wrapping element (this automatically defaults to ``False``
+ when there is no wrapping element [eg: no argument for the
+ `get_syntax_defs` method given]) (default: ``False``).
+
+ .. versionadded:: 0.6
+
+ `lineseparator`
+ This string is output between lines of code. It defaults to ``"\n"``,
+ which is enough to break a line inside ``<pre>`` tags, but you can
+ e.g. set it to ``"<br>"`` to get HTML line breaks.
+
+ .. versionadded:: 0.7
+
+ `lineanchors`
+ If set to a nonempty string, e.g. ``foo``, the formatter will wrap each
+ output line in an anchor tag with an ``id`` (and `name`) of ``foo-linenumber``.
+ This allows easy linking to certain lines.
+
+ .. versionadded:: 0.9
+
+ `linespans`
+ If set to a nonempty string, e.g. ``foo``, the formatter will wrap each
+ output line in a span tag with an ``id`` of ``foo-linenumber``.
+ This allows easy access to lines via javascript.
+
+ .. versionadded:: 1.6
+
+ `anchorlinenos`
+ If set to `True`, will wrap line numbers in <a> tags. Used in
+ combination with `linenos` and `lineanchors`.
+
+ `tagsfile`
+ If set to the path of a ctags file, wrap names in anchor tags that
+ link to their definitions. `lineanchors` should be used, and the
+ tags file should specify line numbers (see the `-n` option to ctags).
+
+ .. versionadded:: 1.6
+
+ `tagurlformat`
+ A string formatting pattern used to generate links to ctags definitions.
+ Available variables are `%(path)s`, `%(fname)s` and `%(fext)s`.
+ Defaults to an empty string, resulting in just `#prefix-number` links.
+
+ .. versionadded:: 1.6
+
+ `filename`
+ A string used to generate a filename when rendering ``<pre>`` blocks,
+ for example if displaying source code. If `linenos` is set to
+ ``'table'`` then the filename will be rendered in an initial row
+ containing a single `<th>` which spans both columns.
+
+ .. versionadded:: 2.1
+
+ `wrapcode`
+ Wrap the code inside ``<pre>`` blocks using ``<code>``, as recommended
+ by the HTML5 specification.
+
+ .. versionadded:: 2.4
+
+ `debug_token_types`
+ Add ``title`` attributes to all token ``<span>`` tags that show the
+ name of the token.
+
+ .. versionadded:: 2.10
+
+
+ **Subclassing the HTML formatter**
+
+ .. versionadded:: 0.7
+
+ The HTML formatter is now built in a way that allows easy subclassing, thus
+ customizing the output HTML code. The `format()` method calls
+ `self._format_lines()` which returns a generator that yields tuples of ``(1,
+ line)``, where the ``1`` indicates that the ``line`` is a line of the
+ formatted source code.
+
+ If the `nowrap` option is set, the generator is the iterated over and the
+ resulting HTML is output.
+
+ Otherwise, `format()` calls `self.wrap()`, which wraps the generator with
+ other generators. These may add some HTML code to the one generated by
+ `_format_lines()`, either by modifying the lines generated by the latter,
+ then yielding them again with ``(1, line)``, and/or by yielding other HTML
+ code before or after the lines, with ``(0, html)``. The distinction between
+ source lines and other code makes it possible to wrap the generator multiple
+ times.
+
+ The default `wrap()` implementation adds a ``<div>`` and a ``<pre>`` tag.
+
+ A custom `HtmlFormatter` subclass could look like this:
+
+ .. sourcecode:: python
+
+ class CodeHtmlFormatter(HtmlFormatter):
+
+ def wrap(self, source, *, include_div):
+ return self._wrap_code(source)
+
+ def _wrap_code(self, source):
+ yield 0, '<code>'
+ for i, t in source:
+ if i == 1:
+ # it's a line of formatted code
+ t += '<br>'
+ yield i, t
+ yield 0, '</code>'
+
+ This results in wrapping the formatted lines with a ``<code>`` tag, where the
+ source lines are broken using ``<br>`` tags.
+
+ After calling `wrap()`, the `format()` method also adds the "line numbers"
+ and/or "full document" wrappers if the respective options are set. Then, all
+ HTML yielded by the wrapped generator is output.

+## Small explanation of the mess below :)
+#
+# The previous version of the LaTeX formatter just assigned a command to
+# each token type defined in the current style. That obviously is
+# problematic if the highlighted code is produced for a different style
+# than the style commands themselves.
+#
+# This version works much like the HTML formatter which assigns multiple
+# CSS classes to each <span> tag, from the most specific to the least
+# specific token type, thus falling back to the parent token type if one
+# is not defined. Here, the classes are there too and use the same short
+# forms given in token.STANDARD_TYPES.
+#
+# Highlighted code now only uses one custom command, which by default is
+# \PY and selectable by the commandprefix option (and in addition the
+# escapes \PYZat, \PYZlb and \PYZrb which haven't been renamed for
+# backwards compatibility purposes).
+#
+# \PY has two arguments: the classes, separated by +, and the text to
+# render in that style. The classes are resolved into the respective
+# style commands by magic, which serves to ignore unknown classes.
+#
+# The magic macros are:
+# * \PY@it, \PY@bf, etc. are unconditionally wrapped around the text
+# to render in \PY@do. Their definition determines the style.
+# * \PY@reset resets \PY@it etc. to do nothing.
+# * \PY@toks parses the list of classes, using magic inspired by the
+# keyval package (but modified to use plusses instead of commas
+# because fancyvrb redefines commas inside its environments).
+# * \PY@tok processes one class, calling the \PY@tok@classname command
+# if it exists.
+# * \PY@tok@classname sets the \PY@it etc. to reflect the chosen style
+# for its class.
+# * \PY resets the style, parses the classnames and then calls \PY@do.
+#
+# Tip: to read this code, print it out in substituted form using e.g.
+# >>> print STYLE_TEMPLATE % {'cp': 'PY'}

+ Format tokens as LaTeX code. This needs the `fancyvrb` and `color`
+ standard packages.
+
+ Without the `full` option, code is formatted as one ``Verbatim``
+ environment, like this:
+
+ .. sourcecode:: latex
+
+ \begin{Verbatim}[commandchars=\\\{\}]
+ \PY{k}{def }\PY{n+nf}{foo}(\PY{n}{bar}):
+ \PY{k}{pass}
+ \end{Verbatim}
+
+ Wrapping can be disabled using the `nowrap` option.
+
+ The special command used here (``\PY``) and all the other macros it needs
+ are output by the `get_style_defs` method.
+
+ With the `full` option, a complete LaTeX document is output, including
+ the command definitions in the preamble.
+
+ The `get_style_defs()` method of a `LatexFormatter` returns a string
+ containing ``\def`` commands defining the macros needed inside the
+ ``Verbatim`` environments.
+
+ Additional options accepted:
+
+ `nowrap`
+ If set to ``True``, don't wrap the tokens at all, not even inside a
+ ``\begin{Verbatim}`` environment. This disables most other options
+ (default: ``False``).
+
+ `style`
+ The style to use, can be a string or a Style subclass (default:
+ ``'default'``).
+
+ `full`
+ Tells the formatter to output a "full" document, i.e. a complete
+ self-contained document (default: ``False``).
+
+ `title`
+ If `full` is true, the title that should be used to caption the
+ document (default: ``''``).
+
+ `docclass`
+ If the `full` option is enabled, this is the document class to use
+ (default: ``'article'``).
+
+ `preamble`
+ If the `full` option is enabled, this can be further preamble commands,
+ e.g. ``\usepackage`` (default: ``''``).
+
+ `linenos`
+ If set to ``True``, output line numbers (default: ``False``).
+
+ `linenostart`
+ The line number for the first line (default: ``1``).
+
+ `linenostep`
+ If set to a number n > 1, only every nth line number is printed.
+
+ `verboptions`
+ Additional options given to the Verbatim environment (see the *fancyvrb*
+ docs for possible values) (default: ``''``).
+
+ `commandprefix`
+ The LaTeX commands used to produce colored output are constructed
+ using this prefix and some letters (default: ``'PY'``).
+
+ .. versionadded:: 0.7
+ .. versionchanged:: 0.10
+ The default is now ``'PY'`` instead of ``'C'``.
+
+ `texcomments`
+ If set to ``True``, enables LaTeX comment lines. That is, LaTex markup
+ in comment tokens is not escaped so that LaTeX can render it (default:
+ ``False``).
+
+ .. versionadded:: 1.2
+
+ `mathescape`
+ If set to ``True``, enables LaTeX math mode escape in comments. That
+ is, ``'$...$'`` inside a comment will trigger math mode (default:
+ ``False``).
+
+ .. versionadded:: 1.2
+
+ `escapeinside`
+ If set to a string of length 2, enables escaping to LaTeX. Text
+ delimited by these 2 characters is read as LaTeX code and
+ typeset accordingly. It has no effect in string literals. It has
+ no effect in comments if `texcomments` or `mathescape` is
+ set. (default: ``''``).
+
+ .. versionadded:: 2.0
+
+ `envname`
+ Allows you to pick an alternative environment name replacing Verbatim.
+ The alternate environment still has to support Verbatim's option syntax.
+ (default: ``'Verbatim'``).

+pyparsing module - Classes and methods to define and execute parsing grammars
+=============================================================================
+
+The pyparsing module is an alternative approach to creating and
+executing simple grammars, vs. the traditional lex/yacc approach, or the
+use of regular expressions. 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
+``"<salutation>, <addressee>!"``), built up using :class:`Word`,
+:class:`Literal`, and :class:`And` elements
+(the :meth:`'+'<ParserElement.__add__>` operators create :class:`And` expressions,
+and the strings are auto-converted to :class:`Literal` expressions)::
+
+ from pip._vendor.pyparsing import Word, alphas
+
+ # define grammar of a greeting
+ greet = Word(alphas) + "," + Word(alphas) + "!"
+
+ hello = "Hello, World!"
+ print(hello, "->", greet.parse_string(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 :class:`'+'<And>`,
+:class:`'|'<MatchFirst>`, :class:`'^'<Or>` and :class:`'&'<Each>` operators.
+
+The :class:`ParseResults` object returned from
+:class:`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
+
+
+Getting Started -
+-----------------
+Visit the classes :class:`ParserElement` and :class:`ParseResults` to
+see the base classes that most other pyparsing
+classes inherit from. Use the docstrings for examples of how to:
+
+ - construct literal match expressions from :class:`Literal` and
+ :class:`CaselessLiteral` classes
+ - construct character word-group expressions using the :class:`Word`
+ class
+ - see how to create repetitive expressions using :class:`ZeroOrMore`
+ and :class:`OneOrMore` classes
+ - use :class:`'+'<And>`, :class:`'|'<MatchFirst>`, :class:`'^'<Or>`,
+ and :class:`'&'<Each>` operators to combine simple expressions into
+ more complex ones
+ - associate names with your parsed results using
+ :class:`ParserElement.setResultsName`
+ - access the parsed data, which is returned as a :class:`ParseResults`
+ object
+ - find some helpful expression short-cuts like :class:`delimitedList`
+ and :class:`oneOf`
+ - find more useful common expressions in the :class:`pyparsing_common`
+ namespace class

+ Define one or more actions to perform when successfully matching parse element definition.
+
+ Parse actions can be called to perform data conversions, do extra validation,
+ update external data structures, or enhance or replace the parsed tokens.
+ Each parse action ``fn`` is a callable method with 0-3 arguments, called as
+ ``fn(s, loc, toks)`` , ``fn(loc, toks)`` , ``fn(toks)`` , or just ``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 :class:`ParseResults` object
+
+ The parsed tokens are passed to the parse action as ParseResults. They can be
+ modified in place using list-style append, extend, and pop operations to update
+ the parsed list elements; and with dictionary-style item set and del operations
+ to add, update, or remove any named results. If the tokens are modified in place,
+ it is not necessary to return them with a return statement.
+
+ Parse actions can also completely replace the given tokens, with another ``ParseResults``
+ object, or with some entirely different object (common for parse actions that perform data
+ conversions). A convenient way to build a new parse result is to define the values
+ using a dict, and then create the return value using :class:`ParseResults.from_dict`.
+
+ If None is passed as the ``fn`` parse action, all previously added parse actions for this
+ expression are cleared.
+
+ Optional keyword arguments:
+
+ - call_during_try = (default= ``False``) indicate if parse action should be run during
+ lookaheads and alternate testing. For parse actions that have side effects, it is
+ important to only call the parse action once it is determined that it is being
+ called as part of a successful parse. For parse actions that perform additional
+ validation, then call_during_try should be passed as True, so that the validation
+ code is included in the preliminary "try" parses.
+
+ Note: the default parsing behavior is to expand tabs in the input string
+ before starting the parsing process. See :class:`parse_string` for more
+ information on parsing strings containing ``<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.

+ :param parseAll: retained for pre-PEP8 compatibility, will be removed in a future release.
+ :raises ParseException: Raised if ``parse_all`` is set and the input string does not match the whole grammar.

+
+ If the input string is required to match the entire grammar, ``parse_all`` flag must be set to ``True``. This
+ is also equivalent to ending the grammar with :class:`StringEnd`().
+
+ To report proper column numbers, ``parse_string`` operates on a copy of the input string where all tabs are
+ converted to spaces (8 spaces per tab, as per the default in ``string.expandtabs``). If the input string
+ contains tabs and the grammar uses parse actions that use the ``loc`` argument to index into the string
+ being parsed, one can ensure a consistent view of the input string by doing one of the following:
+
+ - calling ``parse_with_tabs`` on your grammar before calling ``parse_string`` (see :class:`parse_with_tabs`),
+ - define your parse action using the full ``(s,loc,toks)`` signature, and reference the input string using the
+ parse action's ``s`` argument, or
+ - explicitly expand the tabs in your input string before calling ``parse_string``.
+
+ Examples:

+ By default, partial matches are OK.

+ >>> res = Word('a').parse_string('aaaaabaaa')
+ >>> print(res)
+ ['aaaaa']
+
+ The parsing behavior varies by the inheriting class of this abstract class. Please refer to the children

+ - ``body_chars`` - string of characters that

+ (default=``None``)

+ - ``exact`` - exact number of characters to match (default=0)
+ - ``as_keyword`` - match as a keyword (default=``False``)
+ - ``exclude_chars`` - characters that might be
+ found in the input ``body_chars`` string but which should not be
+ accepted for matching ;useful to define a word of all
+ printables except for one or two characters, for instance
+ (default=``None``)
+
+ :class:`srange` is useful for defining custom character set strings
+ for defining :class:`Word` expressions, using range notation from
+ regular expression character sets.
+
+ A common mistake is to use :class:`Word` to match a specific literal
+ string, as in ``Word("Address")``. Remember that :class:`Word`
+ uses the string argument to define *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 :class:`Literal` or :class:`Keyword`.
+
+ pyparsing includes helper strings for building Words:
+
+ - :class:`alphas`
+ - :class:`nums`
+ - :class:`alphanums`
+ - :class:`hexnums`
+ - :class:`alphas8bit` (alphabetic characters in ASCII range 128-255
+ - accented, tilded, umlauted, etc.)
+ - :class:`punc8bit` (non-alphabetic characters in ASCII range
+ 128-255 - currency, symbols, superscripts, diacriticals, etc.)
+ - :class:`printables` (any non-whitespace character)
+
+ ``alphas``, ``nums``, and ``printables`` are also defined in several
+ Unicode sets - see :class:`pyparsing_unicode``.
+
+ 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)

+ Defined with the following parameters:
+
+ - ``quote_char`` - string of one or more characters defining the
+ quote delimiting string
+ - ``esc_char`` - character to re_escape quotes, typically backslash
+ (default= ``None``)
+ - ``esc_quote`` - special quote sequence to re_escape an embedded quote
+ string (such as SQL's ``""`` to re_escape an embedded ``"``)
+ (default= ``None``)
+ - ``multiline`` - boolean indicating whether quotes can span
+ multiple lines (default= ``False``)
+ - ``unquote_results`` - boolean indicating whether the matched text
+ should be unquoted (default= ``True``)
+ - ``end_quote_char`` - string of one or more characters defining the
+ end of the quote delimited string (default= ``None`` => same as
+ quote_char)
+ - ``convert_whitespace_escapes`` - convert escaped whitespace
+ (``'\t'``, ``'\n'``, etc.) to actual whitespace
+ (default= ``True``)
+
+ Example::
+
+ qs = QuotedString('"')
+ print(qs.search_string('lsjdf "This is the quote" sldjf'))
+ complex_qs = QuotedString('{{', end_quote_char='}}')
+ print(complex_qs.search_string('lsjdf {{This is the "quote"}} sldjf'))
+ sql_qs = QuotedString('"', esc_quote='""')
+ print(sql_qs.search_string('lsjdf "This is the quote with ""embedded"" quotes" sldjf'))
+
+ prints::
+
+ [['This is the quote']]
+ [['This is the "quote"']]

+
+ Parameters:
+
+ - ``blockStatementExpr`` - expression defining syntax of statement that

+ - ``indentStack`` - list created by caller to manage indentation stack

+Requests is an HTTP library, written in Python, for human beings.
+Basic GET usage:
+
+ >>> import requests
+ >>> r = requests.get('https://www.python.org')
+ >>> r.status_code
+ 200
+ >>> b'Python is a programming language' in r.content
+ True
+
+... or POST:

+ >>> payload = dict(key1='value1', key2='value2')
+ >>> r = requests.post('https://httpbin.org/post', data=payload)
+ >>> print(r.text)
+ {
+ ...
+ "form": {

+
+The other HTTP methods are supported - see `requests.api`. Full documentation

+ type such as ``Tuple[int, str]``.
+
+ Type variable tuples can be used in ``Generic`` declarations.
+ Consider the following example::
+
+ class Array(Generic[*Ts]): ...
+
+ The ``Ts`` type variable tuple here behaves like ``tuple[T1, T2]``,
+ where ``T1`` and ``T2`` are type variables. To use these type variables
+ as type parameters of ``Array``, we must *unpack* the type variable tuple using
+ the star operator: ``*Ts``. The signature of ``Array`` then behaves
+ as if we had simply written ``class Array(Generic[T1, T2]): ...``.
+ In contrast to ``Generic[T1, T2]``, however, ``Generic[*Shape]`` allows
+ us to parameterise the class with an *arbitrary* number of type parameters.
+
+ Type variable tuples can be used anywhere a normal ``TypeVar`` can.
+ This includes class definitions, as shown above, as well as function
+ signatures and variable annotations::
+
+ class Array(Generic[*Ts]):
+
+ def __init__(self, shape: Tuple[*Ts]):
+ self._shape: Tuple[*Ts] = shape

+ :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.

+This module provides a pool manager that uses Google App Engine's
+`URLFetch Service <https://cloud.google.com/appengine/docs/python/urlfetch>`_.
+
+Example usage::
+
+ from pip._vendor.urllib3 import PoolManager
+ from pip._vendor.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.

+TLS with SNI_-support for Python 2. Follow these instructions if you would
+like to verify TLS 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:
+
+.. code-block:: bash
+
+ $ python -m 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:
+
+.. code-block:: python
+
+ try:
+ import pip._vendor.urllib3.contrib.pyopenssl as pyopenssl
+ 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`_).

+SecureTranport support for urllib3 via ctypes.
+
+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.
+
+To use this module, simply import and inject it::
+
+ import pip._vendor.urllib3.contrib.securetransport as securetransport
+ securetransport.inject_into_urllib3()
+
+Happy TLSing!
+
+This code is a bastardised version of the code found in Will Bond's oscrypto
+library. An enormous debt is owed to him for blazing this trail for us. For
+that reason, this code should be considered to be covered both by urllib3's

+This module contains provisional support for SOCKS proxies from within
+urllib3. This module supports SOCKS4, SOCKS4A (an extension of SOCKS4), and
+SOCKS5. To enable its functionality, either install PySocks or install this
+module with the ``socks`` extra.
+
+The SOCKS implementation supports the full range of urllib3 features. It also
+supports the following SOCKS features:
+
+- SOCKS4A (``proxy_url='socks4a://...``)
+- SOCKS4 (``proxy_url='socks4://...``)
+- SOCKS5 with remote DNS (``proxy_url='socks5h://...``)
+- SOCKS5 with local DNS (``proxy_url='socks5://...``)
+- Usernames and passwords for the SOCKS proxy
+
+.. note::

+
+ By default, this is disabled with ``None``.

+Package resource API
+--------------------
+
+A resource is a logical file contained within a package, or a logical
+subdirectory thereof. 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.

+pyparsing module - Classes and methods to define and execute parsing grammars
+=============================================================================
+
+The pyparsing module is an alternative approach to creating and executing simple grammars,
+vs. the traditional lex/yacc approach, or the use of regular expressions. 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
+
+
+Getting Started -
+-----------------
+Visit the classes L{ParserElement} and L{ParseResults} to see the base classes that most other pyparsing
+classes inherit from. Use the docstrings for examples of how to:
+ - construct literal match expressions from L{Literal} and L{CaselessLiteral} classes
+ - construct character word-group expressions using the L{Word} class
+ - see how to create repetitive expressions using L{ZeroOrMore} and L{OneOrMore} classes
+ - use L{'+'<And>}, L{'|'<MatchFirst>}, L{'^'<Or>}, and L{'&'<Each>} operators to combine simple expressions into more complex ones
+ - associate names with your parsed results using L{ParserElement.setResultsName}
+ - find some helpful expression short-cuts like L{delimitedList} and L{oneOf}
+ - find more useful common expressions in the L{pyparsing_common} namespace class

+ 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=",")

+# This implements an LR parser that is constructed from grammar rules defined
+# as Python functions. The grammar 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." Modify the code at your
+# own risk!

+ # LALR(1) parsing is almost exactly the same as SLR except that instead of
+ # relying upon Follow() sets when performing reductions, a more selective
+ # lookahead set that incorporates the state of the LR(0) machine is utilized.
+ # Thus, we mainly just have to focus on calculating the lookahead sets.
+ #
+ # The method used here is due to DeRemer and Pennelo (1982).

+
+ What's Pyverilog?
+ ==============================
+
+ Pyverilog is an open-source hardware design processing toolkit for Verilog HDL. All source codes are written in Python.
+
+ Pyverilog includes **(1) code parser, (2) dataflow analyzer, (3) control-flow analyzer and (4) code generator**.
+ You can create your own design analyzer, code translator and code generator of Verilog HDL based on this toolkit.
+
+
+ Contribute to Pyverilog
+ ==============================
+
+ Pyverilog project always welcomes questions, bug reports, feature proposals, and pull requests on [GitHub](https://github.com/PyHDI/Pyverilog).

+
+
+ Tools
+ ==============================
+
+ This software includes various tools for Verilog HDL design.
+
+ * vparser: Code parser to generate AST (Abstract Syntax Tree) from source codes of Verilog HDL.
+ * dataflow: Dataflow analyzer with an optimizer to remove redundant expressions and some dataflow handling tools.
+ * controlflow: Control-flow analyzer with condition analyzer that identify when a signal is activated.
+ * ast\_code\_generator: Verilog HDL code generator from AST.
+
+
+ Getting Started
+ ==============================
+
+ First, please prepare a Verilog HDL source file as below. The file name is 'test.v'.
+ This sample design adds the input value internally whtn the enable signal is asserted. Then is outputs its partial value to the LED.
+
+ ```verilog
+ module top
+ (
+ input CLK,
+ input RST,
+ input enable,
+ input [31:0] value,
+ output [7:0] led
+ );
+ reg [31:0] count;
+ reg [7:0] state;
+ assign led = count[23:16];
+ always @(posedge CLK) begin
+ if(RST) begin
+ count <= 0;
+ state <= 0;
+ end else begin
+ if(state == 0) begin
+ if(enable) state <= 1;
+ end else if(state == 1) begin
+ state <= 2;
+ end else if(state == 2) begin
+ count <= count + value;
+ state <= 0;
+ end
+ end
+ end
+ endmodule
+ ```
+
+ Code parser
+ ------------------------------
+
+ Let's try syntax analysis. Please type the command as below.
+
+ ```
+ python3 pyverilog/examples/example_parser.py test.v
+ ```
+
+ Then you got the result as below. The result of syntax analysis is displayed.

+
+ Dataflow analyzer
+ ------------------------------
+
+ Let's try dataflow analysis. Please type the command as below.
+
+ ```
+ python3 pyverilog/examples/example_dataflow_analyzer.py -t top test.v
+ ```
+
+ Then you got the result as below. The result of each signal definition and each signal assignment are displayed.
+
+ ```
+ Directive:
+ Instance:
+ (top, 'top')
+ Term:
+ (Term name:top.led type:{'Output'} msb:(IntConst 7) lsb:(IntConst 0))
+ (Term name:top.enable type:{'Input'} msb:(IntConst 0) lsb:(IntConst 0))
+ (Term name:top.CLK type:{'Input'} msb:(IntConst 0) lsb:(IntConst 0))
+ (Term name:top.count type:{'Reg'} msb:(IntConst 31) lsb:(IntConst 0))
+ (Term name:top.state type:{'Reg'} msb:(IntConst 7) lsb:(IntConst 0))
+ (Term name:top.RST type:{'Input'} msb:(IntConst 0) lsb:(IntConst 0))
+ (Term name:top.value type:{'Input'} msb:(IntConst 31) lsb:(IntConst 0))
+ Bind:
+ (Bind dest:top.count tree:(Branch Cond:(Terminal top.RST) True:(IntConst 0) False:(Branch Cond:(Operator Eq Next:(Terminal top.state),(IntConst 0)) False:(Branch Cond:(Operator Eq Next:(Terminal top.state),(IntConst 1)) False:(Branch Cond:(Operator Eq Next:(Terminal top.state),(IntConst 2)) True:(Operator Plus Next:(Terminal top.count),(Terminal top.value)))))))
+ (Bind dest:top.state tree:(Branch Cond:(Terminal top.RST) True:(IntConst 0) False:(Branch Cond:(Operator Eq Next:(Terminal top.state),(IntConst 0)) True:(Branch Cond:(Terminal top.enable) True:(IntConst 1)) False:(Branch Cond:(Operator Eq Next:(Terminal top.state),(IntConst 1)) True:(IntConst 2) False:(Branch Cond:(Operator Eq Next:(Terminal top.state),(IntConst 2)) True:(IntConst 0))))))
+ (Bind dest:top.led tree:(Partselect Var:(Terminal top.count) MSB:(IntConst 23) LSB:(IntConst 16)))
+ ```
+
+ Let's view the result of dataflow analysis as a picture file. Now we select 'led' as the target. Please type the command as below. In this example, Graphviz and Pygraphviz are installed.
+
+ ```
+ python3 pyverilog/examples/example_graphgen.py -t top -s top.led test.v
+ ```
+
+ Then you got a png file (out.png). The picture shows that the definition of 'led' is a part-selection of 'count' from 23-bit to 16-bit.
+
+ 
+
+ Control-flow analyzer
+ ------------------------------
+
+ Let's try control-flow analysis. Please type the command as below. In this example, Graphviz and Pygraphviz are installed. If don't use Graphviz, please append "--nograph" option.
+
+ ```
+ python3 pyverilog/examples/example_controlflow_analyzer.py -t top test.v
+ ```
+
+ Then you got the result as below. The result shows that the state machine structure and transition conditions to the next state in the state machine.
+
+ ```
+ FSM signal: top.count, Condition list length: 4
+ FSM signal: top.state, Condition list length: 5
+ Condition: (Ulnot, Eq), Inferring transition condition
+ Condition: (Eq, top.enable), Inferring transition condition
+ Condition: (Ulnot, Ulnot, Eq), Inferring transition condition
+ # SIGNAL NAME: top.state
+ # DELAY CNT: 0
+ 0 --(top_enable>'d0)--> 1
+ 1 --None--> 2
+ 2 --None--> 0
+ Loop
+ (0, 1, 2)
+ ```
+
+ You got also a png file (top_state.png), if you did not append "--nograph". The picture shows that the graphical structure of the state machine.
+
+ 
+
+ Code generator
+ ------------------------------
+
+ Finally, let's try code generation. Please prepare a Python script as below. The file name is 'test.py'.
+ A Verilog HDL code is represented by using the AST classes defined in 'vparser.ast'.
+
+ ```python
+ from __future__ import absolute_import
+ from __future__ import print_function
+ import sys
+ import os
+ import pyverilog.vparser.ast as vast
+ from pyverilog.ast_code_generator.codegen import ASTCodeGenerator
+
+ def main():
+ datawid = vast.Parameter( 'DATAWID', vast.Rvalue(vast.IntConst('32')) )
+ params = vast.Paramlist( [datawid] )
+ clk = vast.Ioport( vast.Input('CLK') )
+ rst = vast.Ioport( vast.Input('RST') )
+ width = vast.Width( vast.IntConst('7'), vast.IntConst('0') )
+ led = vast.Ioport( vast.Output('led', width=width) )
+ ports = vast.Portlist( [clk, rst, led] )
+
+ width = vast.Width( vast.Minus(vast.Identifier('DATAWID'), vast.IntConst('1')), vast.IntConst('0') )
+ count = vast.Reg('count', width=width)
+
+ assign = vast.Assign(
+ vast.Lvalue(vast.Identifier('led')),
+ vast.Rvalue(
+ vast.Partselect(
+ vast.Identifier('count'), # count
+ vast.Minus(vast.Identifier('DATAWID'), vast.IntConst('1')), # [DATAWID-1:
+ vast.Minus(vast.Identifier('DATAWID'), vast.IntConst('8'))))) # :DATAWID-8]
+
+ sens = vast.Sens(vast.Identifier('CLK'), type='posedge')
+ senslist = vast.SensList([ sens ])
+
+ assign_count_true = vast.NonblockingSubstitution(
+ vast.Lvalue(vast.Identifier('count')),
+ vast.Rvalue(vast.IntConst('0')))
+ if0_true = vast.Block([ assign_count_true ])
+
+ # count + 1
+ count_plus_1 = vast.Plus(vast.Identifier('count'), vast.IntConst('1'))
+ assign_count_false = vast.NonblockingSubstitution(
+ vast.Lvalue(vast.Identifier('count')),
+ vast.Rvalue(count_plus_1))
+ if0_false = vast.Block([ assign_count_false ])
+
+ if0 = vast.IfStatement(vast.Identifier('RST'), if0_true, if0_false)
+ statement = vast.Block([ if0 ])
+
+ always = vast.Always(senslist, statement)
+
+ items = []
+ items.append(count)
+ items.append(assign)
+ items.append(always)
+
+ ast = vast.ModuleDef("top", params, ports, items)
+
+ codegen = ASTCodeGenerator()
+ rslt = codegen.visit(ast)
+ print(rslt)
+
+ if __name__ == '__main__':
+ main()
+ ```
+
+ Please type the command as below at the same directory with Pyverilog.
+
+ ```
+ python3 test.py
+ ```
+
+ Then Verilog HDL code generated from the AST instances is displayed.
+
+ ```verilog
+ module top #
+ (
+ parameter DATAWID = 32
+ )
+ (
+ input CLK,
+ input RST,
+ output [7:0] led
+ );
+
+ reg [DATAWID-1:0] count;
+ assign led = count[DATAWID-1:DATAWID-8];
+
+ always @(posedge CLK) begin
+ if(RST) begin
+ count <= 0;
+ end else begin
+ count <= count + 1;
+ end
+ end
+
+
+ endmodule
+ ```

+pyparsing module - Classes and methods to define and execute parsing grammars
+=============================================================================
+
+The pyparsing module is an alternative approach to creating and executing simple grammars,
+vs. the traditional lex/yacc approach, or the use of regular expressions. 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
+
+
+Getting Started -
+-----------------
+Visit the classes L{ParserElement} and L{ParseResults} to see the base classes that most other pyparsing
+classes inherit from. Use the docstrings for examples of how to:
+ - construct literal match expressions from L{Literal} and L{CaselessLiteral} classes
+ - construct character word-group expressions using the L{Word} class
+ - see how to create repetitive expressions using L{ZeroOrMore} and L{OneOrMore} classes
+ - use L{'+'<And>}, L{'|'<MatchFirst>}, L{'^'<Or>}, and L{'&'<Each>} operators to combine simple expressions into more complex ones
+ - associate names with your parsed results using L{ParserElement.setResultsName}
+ - find some helpful expression short-cuts like L{delimitedList} and L{oneOf}
+ - find more useful common expressions in the L{pyparsing_common} namespace class

+
+ 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

+
+ L{srange} is useful for defining custom character set strings for defining

+
+ A common mistake is to use C{Word} to match a specific literal string, as in

+ "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}.
+

+ Token for matching strings that are delimited by quoting characters.
+
+ Defined with the following parameters:
+ - quoteChar - string of one or more characters defining the quote delimiting string
+ - escChar - character to escape quotes, typically backslash (default=C{None})
+ - escQuote - special quote sequence to escape an embedded quote string (such as SQL's "" to escape an embedded ") (default=C{None})
+ - multiline - boolean indicating whether quotes can span multiple lines (default=C{False})
+ - unquoteResults - boolean indicating whether the matched text should be unquoted (default=C{True})
+ - endQuoteChar - string of one or more characters defining the end of the quote delimited string (default=C{None} => same as quoteChar)
+ - convertWhitespaceEscapes - convert escaped whitespace (C{'\t'}, C{'\n'}, etc.) to actual whitespace (default=C{True})
+
+ Example::
+ qs = QuotedString('"')
+ print(qs.searchString('lsjdf "This is the quote" sldjf'))

+"""A PEP 517 interface to setuptools
+
+Previously, when a user or a command line tool (let's call it a "frontend")
+needed to make a request of setuptools to take a certain action, for
+example, generating a list of installation requirements, the frontend would
+would call "setup.py egg_info" or "setup.py bdist_wheel" on the command line.
+
+PEP 517 defines a different method of interfacing with setuptools. Rather
+than calling "setup.py" directly, the frontend should:
+
+ 1. Set the current directory to the directory with a setup.py file
+ 2. Import this module into a safe python interpreter (one in which
+ setuptools can potentially set global variables or crash hard).
+ 3. Call one of the functions defined in PEP 517.
+
+What each function does is defined in PEP 517. However, here is a "casual"
+definition of the functions (this definition should not be relied on for
+bug reports or API stability):
+
+ - `build_wheel`: build a wheel in the folder and return the basename
+ - `get_requires_for_build_wheel`: get the `setup_requires` to build
+ - `prepare_metadata_for_build_wheel`: get the `install_requires`
+ - `build_sdist`: build an sdist in the folder and return the basename
+ - `get_requires_for_build_sdist`: get the `setup_requires` to build
+
+Again, this is not a formal definition! Just a "taste" of the module.

+
+class Distribution(_Distribution):
+ """Distribution with support for features, tests, and package data
+
+ This is an enhanced version of 'distutils.dist.Distribution' that
+ effectively adds the following new optional keyword arguments to 'setup()':
+
+ 'install_requires' -- a string or sequence of strings specifying project
+ versions that the distribution requires when installed, in the format
+ used by 'pkg_resources.require()'. They will be installed
+ automatically when the package is installed. If you wish to use
+ packages that are not available in PyPI, or want to give your users an
+ alternate download location, you can add a 'find_links' option to the
+ '[easy_install]' section of your project's 'setup.cfg' file, and then
+ setuptools will scan the listed web pages for links that satisfy the
+ requirements.
+
+ 'extras_require' -- a dictionary mapping names of optional "extras" to the
+ additional requirement(s) that using those extras incurs. For example,
+ this::
+
+ extras_require = dict(reST = ["docutils>=0.3", "reSTedit"])
+
+ indicates that the distribution can optionally provide an extra
+ capability called "reST", but it can only be used if docutils and
+ reSTedit are installed. If the user installs your package using
+ EasyInstall and requests one of your extras, the corresponding
+ additional requirements will be installed if needed.
+
+ 'features' **deprecated** -- a dictionary mapping option names to
+ 'setuptools.Feature'
+ objects. Features are a portion of the distribution that can be
+ included or excluded based on user options, inter-feature dependencies,
+ and availability on the current system. Excluded features are omitted
+ from all setup commands, including source and binary distributions, so
+ you can create multiple distributions from the same source tree.
+ Feature names should be valid Python identifiers, except that they may
+ contain the '-' (minus) sign. Features can be included or excluded
+ via the command line options '--with-X' and '--without-X', where 'X' is
+ the name of the feature. Whether a feature is included by default, and
+ whether you are allowed to control this from the command line, is
+ determined by the Feature object. See the 'Feature' class for more
+ information.
+
+ 'test_suite' -- the name of a test suite to run for the 'test' command.
+ If the user runs 'python setup.py test', the package will be installed,
+ and the named test suite will be run. The format is the same as
+ would be used on a 'unittest.py' command line. That is, it is the
+ dotted name of an object to import and call to generate a test suite.
+
+ 'package_data' -- a dictionary mapping package names to lists of filenames
+ or globs to use to find data files contained in the named packages.
+ If the dictionary has filenames or globs listed under '""' (the empty
+ string), those names will be searched for in every package, in addition
+ to any names for the specific package. Data files found using these
+ names/globs will be installed along with the package, in the same
+ location as the package. Note that globs are allowed to reference
+ the contents of non-package subdirectories, as long as you use '/' as
+ a path separator. (Globs are automatically converted to
+ platform-specific paths at runtime.)
+
+ In addition to these new keywords, this class also has several new methods
+ for manipulating the distribution's contents. For example, the 'include()'
+ and 'exclude()' methods can be thought of as in-place add and subtract
+ commands that add or remove packages, modules, extensions, and so on from
+ the distribution. They are used by the feature subsystem to configure the
+ distribution for the included and excluded features.

+ A subset of the distribution that can be excluded if unneeded/wanted
+
+ Features are created using these keyword arguments:
+
+ 'description' -- a short, human readable description of the feature, to
+ be used in error messages, and option help messages.
+
+ 'standard' -- if true, the feature is included by default if it is
+ available on the current system. Otherwise, the feature is only
+ included if requested via a command line '--with-X' option, or if
+ another included feature requires it. The default setting is 'False'.
+
+ 'available' -- if true, the feature is available for installation on the
+ current system. The default setting is 'True'.
+
+ 'optional' -- if true, the feature's inclusion can be controlled from the
+ command line, using the '--with-X' or '--without-X' options. If
+ false, the feature's inclusion status is determined automatically,
+ based on 'availabile', 'standard', and whether any other feature
+ requires it. The default setting is 'True'.
+
+ 'require_features' -- a string or sequence of strings naming features
+ that should also be included if this feature is included. Defaults to
+ empty list. May also contain 'Require' objects that should be
+ added/removed from the distribution.
+
+ 'remove' -- a string or list of strings naming packages to be removed
+ from the distribution if this feature is *not* included. If the
+ feature *is* included, this argument is ignored. This argument exists
+ to support removing features that "crosscut" a distribution, such as
+ defining a 'tests' feature that removes all the 'tests' subpackages
+ provided by other features. The default for this argument is an empty
+ list. (Note: the named package(s) or modules must exist in the base
+ distribution when the 'setup()' function is initially called.)
+
+ other keywords -- any other keyword arguments are saved, and passed to
+ the distribution's 'include()' and 'exclude()' methods when the
+ feature is included or excluded, respectively. So, for example, you
+ could pass 'packages=["a","b"]' to cause packages 'a' and 'b' to be
+ added or removed from the distribution as appropriate.
+
+ A feature must include at least one 'requires', 'remove', or other
+ keyword argument. Otherwise, it can't affect the distribution in any way.
+ Note also that you can subclass 'Feature' to create your own specialized
+ feature types that modify the distribution in other ways when included or
+ excluded. See the docstrings for the various methods here for more detail.
+ Aside from the methods, the only feature attributes that distributions look
+ at are 'description' and 'optional'.
