marxists.org-UserCSS VS lua-filters

The closest thing to this I've seen so far is a browser plug-in that overrides marxists.org's css: https://github.com/ArkansasWorker/marxists.org-UserCSS

Use a browser extension to improve the reading experience – here's a UserCSS script I made for reading the free site Marxists.org. It has various themes, typography options, and dark mode.

The programming challenge I think would be to write a converter from marxist.org html to markdown or org-mode. I was thinking of pandoc with a lua filter (see also) for marxist.org html unfortunately my lua is terrible.

TikZ: Not sure if it answers your question, but Quarto has some support for TikZ. It's also possible to use a Lua filter, as described in the Lua filter docs. See also the diagram-generator filter.

You can do inline diagrams with pandoc using this filter https://github.com/pandoc/lua-filters/tree/master/diagram-generator

Have a look at this repo for more awesome things you can do with pandoc. https://github.com/pandoc/lua-filters

set statusline= ... set statusline+=%{WordCount()} ``` This word count can't be 100% accurate due to the markup in markdown being counted, but this Pandoc filter can! https://github.com/pandoc/lua-filters/blob/master/wordcount/wordcount.lua

Sorry for the late reply, but the include-files Lua filter here sounds good for this. I've been getting into writing these kind of filters lately myself and its adding a whole new dimension of possibilities for whats possible with Pandoc.
