Please Add Support for sphinx extensions

[adam-grant-hendry]

Context

Several sphinx extensions are used in older restructured text projects, like;

• numpydoc
• sphinxcontrib

and several others. Lacking support for these prevents other project from transitioning towards using myst-parser.

e.g. I will not switch over whilst these extensions are unavailable. I am able to achieve more by using restructured text, and these are still able to be used with the sphinx-themes.org themes.

Proposal

The proposal is to add extended support for sphinx extensions to the Sphinx parser in myst-parser.

Tasks and updates

TBD

Hey @adam-grant-hendry I'm not sure what you mean here; you can use any extension alongside myst-parser, as indeed is the case for the building of the documentation here:

MyST-Parser/docs/conf.py

Line 28 in 28725fc

extensions = [

Is there a particular issue you have with compatibility on a certain extension?

Hi @chrisjsewell,

Ah, perhaps I misunderstood: the numpydocs documentation details using rst-style directives, so I wasn't sure if there would be a conflict with using rst-style directives in docstrings if I wanted to use myst-parser syntax in my documentation files...?

One thing for certain that would be excellent is support for adding/specifying 3rd-party MarkdownIt plugins via the conf.py (Issue #632).
