Python Documentation README
~~~~~~~~~~~~~~~~~~~~~~~~~~~
This directory contains the reStructuredText (reST) sources to the Python
documentation. You don't need to build them yourself, `prebuilt versions are
available <https://docs.python.org/dev/download.html>`_.
Documentation on authoring Python documentation, including information about
both style and markup, is available in the "`Documenting Python
<https://devguide.python.org/documenting/>`_" chapter of the
developers guide.
Building the docs
=================
The documentation is built with several tools which are not included in this
tree but are maintained separately and are available from
`PyPI <https://pypi.org/>`_.
* `Sphinx <https://pypi.org/project/Sphinx/>`_
* `blurb <https://pypi.org/project/blurb/>`_
You could manually create a virtual environment and install them, but there is
a ``Makefile`` already set up to do this for you, as long as you have a working
Python 3 interpreter available.
Using make
----------
A Makefile has been prepared so that (on Unix), after you change into the
``Doc/`` directory you can simply run ::
make html
By default, if the virtual environment is not created, the Makefile will
look for instances of sphinxbuild and blurb installed on your process PATH
(configurable with the SPHINXBUILD and BLURB variables).
On Windows, we try to emulate the Makefile as closely as possible with a
``make.bat`` file.
To use a Python interpreter that's not called ``python3``, use the standard
way to set Makefile variables, using e.g. ::
make html PYTHON=python
On Windows, set the PYTHON environment variable instead.
To use a specific sphinx-build (something other than ``sphinx-build``), set
the SPHINXBUILD variable.
Available make targets are:
* "clean", which removes all build files.
* "venv", which creates a virtual environment with all necessary tools
installed.
* "html", which builds standalone HTML files for offline viewing.
* "htmlview", which re-uses the "html" builder, but then opens the main page
in your default web browser.
* "htmlhelp", which builds HTML files and a HTML Help project file usable to
convert them into a single Compiled HTML (.chm) file -- these are popular
under Microsoft Windows, but very handy on every platform.
To create the CHM file, you need to run the Microsoft HTML Help Workshop
over the generated project (.hhp) file. The make.bat script does this for
you on Windows.
* "latex", which builds LaTeX source files as input to "pdflatex" to produce
PDF documents.
* "text", which builds a plain text file for each source file.
* "epub", which builds an EPUB document, suitable to be viewed on e-book
readers.
* "linkcheck", which checks all external references to see whether they are
broken, redirected or malformed, and outputs this information to stdout as
well as a plain-text (.txt) file.
* "changes", which builds an overview over all versionadded/versionchanged/
deprecated items in the current version. This is meant as a help for the
writer of the "What's New" document.
* "coverage", which builds a coverage overview for standard library modules and
C API.
* "pydoc-topics", which builds a Python module containing a dictionary with
plain text documentation for the labels defined in
`tools/pyspecific.py` -- pydoc needs these to show topic and keyword help.
* "suspicious", which checks the parsed markup for text that looks like
malformed and thus unconverted reST.
* "check", which checks for frequent markup errors.
* "serve", which serves the build/html directory on port 8000.
* "dist", (Unix only) which creates distributable archives of HTML, text,
PDF, and EPUB builds.
Without make
------------
Install the Sphinx package and its dependencies from PyPI. In this situation,
you'll have to create a virtual environment manually, and install Sphinx into
it. Change into the ``Doc`` directory and run ::
$ python3 -m venv venv
$ source venv/bin/activate
(venv) $ pip install Sphinx
(venv) $ sphinx-build -b<builder> . build/<builder>
where ``<builder>`` is one of html, text, latex, or htmlhelp (for explanations
see the make targets above).
Contributing
============
Bugs in the content should be reported to the
`Python bug tracker <https://bugs.python.org>`_.
Bugs in the toolset should be reported to the tools themselves.
You can also send a mail to the Python Documentation Team at docs@python.org,
and we will process your request as soon as possible.
If you want to help the Documentation Team, you are always welcome. Just send
a mail to docs@python.org.
