Python Enhancement Proposals

The PEPs in this repo are published automatically on the web at
https://www.python.org/dev/peps/. To learn more about the purpose of
PEPs and how to go about writing a PEP, please start reading at PEP 1
(``pep-0001.txt`` in this repo). Note that PEP 0, the index PEP, is
now automatically generated, and not committed to the repo.
Contributing to PEPs
====================
See the `Contributing Guidelines <./CONTRIBUTING.rst>`_.
reStructuredText for PEPs
=========================
Original PEP source should be written in reStructuredText format,
which is a constrained version of plaintext, and is described in
PEP 12. Older PEPs were often written in a more mildly restricted
plaintext format, as described in PEP 9. The ``pep2html.py``
processing and installation script knows how to produce the HTML
for either PEP format.
2011-03-26 13:11:51 -04:00
For processing reStructuredText format PEPs, you need the docutils
package, which is available from `PyPI <https://pypi.org/>`_.
If you have pip, ``pip install docutils`` should install it.

Generating the PEP Index
========================
PEP 0 is automatically generated based on the metadata headers in other
PEPs. The script handling this is ``genpepindex.py``, with supporting
libraries in the ``pep0`` directory.
Checking PEP formatting and rendering
=====================================
2013-11-29 13:34:39 -05:00
Do not commit changes with bad formatting. To check the formatting of
a PEP, use the Makefile. In particular, to generate HTML for PEP 999,
your source code should be in ``pep-0999.rst`` and the HTML will be
generated to ``pep-0999.html`` by the command ``make pep-0999.html``.
The default Make target generates HTML for all PEPs.
If you don't have Make, use the ``pep2html.py`` script directly.
Generating HTML for python.org
==============================
python.org includes its own helper modules to render PEPs as HTML, with
suitable links back to the source pages in the version control repository.
These can be found at https://github.com/python/pythondotorg/tree/master/peps
When making changes to the PEP management process that may impact python.org's
rendering pipeline:
* Clone the python.org repository from https://github.com/python/pythondotorg/
* Get set up for local python.org development as per
https://pythondotorg.readthedocs.io/install.html#manual-setup
* Adjust ``PEP_REPO_PATH`` in ``pydotorg/settings/local.py`` to refer to your
local clone of the PEP repository
* Run ``./manage.py generate_pep_pages`` as described in
https://pythondotorg.readthedocs.io/pep_generation.html
