Building PEPs Locally

Whilst editing a PEP, it is useful to review the rendered output locally. This can also be used to check that the PEP is valid reStructuredText before submission to the PEP editors.

The rest of this document assumes you are working from a local clone of the PEPs repository, with Python 3.9 or later installed.

Render PEPs locally

1. Create a virtual environment and install requirements:
   make venv

   If you don’t have access to make, run:

   PS> python -m venv .venv PS> .\.venv\Scripts\activate (venv) PS> python -m pip install --upgrade pip (venv) PS> python -m pip install -r requirements.txt
2. (Optional) Delete prior build files. Generally only needed when making changes to the rendering system itself.
   rm -rf build
3. Run the build script:
   make html

   If you don’t have access to make, run:

   (venv) PS> python build.py
4. Navigate to the build directory of your PEPs repo to find the HTML pages. PEP 0 provides a formatted index, and may be a useful reference.

build.py tools

Several additional tools can be run through build.py, or the Makefile.

Note that before using build.py you must activate the virtual environment created earlier:

Or on Windows:

Check links

Check the validity of links within PEP sources (runs the Sphinx linkchecker).
