better code highlighting

[Qubus0]

code highlighting looks merely passable right now

<- engine |vs| docs ->

This is mostly down to the Pygments lexer for gdscript being outdated, since that is what mkdocs material uses.

Pygments allows to add custom lexers https://pygments.org/docs/lexerdevelopment/, so we could update the current one and load it instead (since we don't really have time for that change to propagate through both pygments and mkdocs material)

we have these css classes available to use https://github.com/squidfunk/mkdocs-material/blob/master/src/templates/assets/stylesheets/main/extensions/pymdownx/_highlight.scss

the glaring issues right now are

• function definitions (.kd perhaps)
• function calls (.nf)
• classes both custom and native (they use different colors, .nc and .nb perhaps)
• types (fixed already)

less noticeable are

• control flow keywords (could use .kr)
• @ globalscope methods like print (.nn, far fetched)

I got some work down on this, see pygments-gdscript
