Use new markdown-it plugins

[chrisjsewell]

Essentially, this plugin should eventually mirror: https://github.com/executablebooks/myst-vs-code/blob/master/src/extension.ts

A few things to consider here:

1. We want configuration to enable MyST syntax extensions; this should be easy to achieve here
2. the VS extension allows loading the CSS provided by markdown-it-docutils: https://github.com/executablebooks/myst-vs-code/blob/c8c96542171ebe6ccdd896cf8337a5ffffeb73d4/package.json#L115. Can we achieve that here

and yeh, as I've just mention on a jupyter thread, you can check out some of the plugin rendering at:

• https://executablebooks.github.io/markdown-it-docutils
• https://executablebooks.github.io/markdown-it-amsmath
• https://executablebooks.github.io/markdown-it-dollarmath

[chrisjsewell]

Also to note, there is still activity going on around these plugins: executablebooks/meta#449

Once some more of those are merged in we can merge jupyter-book/mystmd#33 and then this package can consume the updates with a version bump. I think it is worth combining and having a myst-specific export (which this package is meant for).

I am planning on getting back to the PRs that you reviewed last week today or tomorrow.

[chrisjsewell]

Yep indeed 👍 just wanted to make @agoose77 of the changes, and start thinking about the config/css points

[agoose77]

Appreciate it all, I'm following this remotely!

[agoose77]

So, it seems to me that we have the following top-level plugins that we need to expose/require as jupyterlab-markup plugins:

• markdown-it-front-matter
• markdown-it-footnote*
• markdown-it-docutils
• markdown-it-dollarmath
• markdown-it-amsmath
• markdown-it-deflist*
• markdown-it-task-lists*

* already provided by jupyterlab-markup

[chrisjsewell]

Yep, plus there are some "small" plugins currently directly implemented in https://github.com/executablebooks/myst-vs-code/blob/master/src/mdPlugins.ts

[agoose77]

Could we move that inline plugin into a new / existing package(s)?

[chrisjsewell]

most certainly, this is where I was thinking markdown-it-myst might come in useful

[agoose77]

Ah OK. I'm not 100% confident with the entire MyST landscape yet, so I'm not clear on where everything goes. In my head, I envisage markdown-it-myst being an empty meta-package that just depends upon the building blocks of a MyST Markdown variant. In that case, it would perhaps be ideal if this small mdPlugins belonged to the "another" markdown-it-myst-extras package?
