php-src docs

This is the home of the php-src internal documentation, hosted at php.github.io/php-src/. It is in very early stages, but is intended to become the primary place where new information about php-src is documented. Over time, it is expected to replace various mediums like:

• https://www.phpinternalsbook.com/
• https://wiki.php.net/internals
• Blogs from contributors

How to build

python 3 and pip are required.

cd docs
# Recommended: Initialize and activate a Python virtual environment
pip install --upgrade pip
pip install -r requirements.txt
make html

That's it! You can view the documentation under ./build/html/index.html in your browser.

Formatting

The files in this documentation are formatted using the rstfmt tool.

rstfmt -w 100 source

This tool is not perfect. It breaks on custom directives, so we might switch to either a fork or something else in the future.
