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.

Documentation on authoring Python documentation, including information about both style and markup, is available in the "Documenting Python" 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.

The easiest way to install these tools is to create a virtual environment and install the tools into there.

Using make

To get started on Unix, you can create a virtual environment and build documentation with the commands:

make venv
make html

The virtual environment in the venv directory will contain all the tools necessary to build the documentation downloaded and installed from PyPI. If you'd like to create the virtual environment in a different location, you can specify it using the VENVDIR variable.

You can also skip creating the virtual environment altogether, in which case the Makefile will look for instances of sphinx-build 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. If you need to specify the Python interpreter to use, set the PYTHON environment variable.

Available make targets are:

"clean", which removes all build files and the virtual environment.
"clean-venv", which removes the virtual environment directory.
"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.
"htmllive", which re-uses the "html" builder, rebuilds the docs, starts a local server, and automatically reloads the page in your browser when you make changes to reST files (Unix only).
"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.
"check", which checks for frequent markup errors.
"dist", (Unix only) which creates distributable archives of HTML, text, PDF, and EPUB builds.

Without make

First, install the tool dependencies from PyPI.

Then, from the Doc directory, run

sphinx-build -b<builder> . build/<builder>

where <builder> is one of html, text, latex, or htmlhelp (for explanations see the make targets above).

Deprecation header

You can define the outdated variable in html_context to show a red banner on each page redirecting to the "latest" version.

The link points to the same page on /3/, sadly for the moment the language is lost during the process.
