Description

A bit of syntax highlighting goes a long way towards making things more readable. Right now we have a little emacs mode and an independent syntax highlighter for the HTML renderings using parser combinators. Does anyone know of a portable solution that lets us define a bunch of regexes and generate modes for vim, emacs, sublime etc?

Contributor guide

Research direction
Research existing portable syntax highlighting solutions like highlight, Pygments, or Tree sitter. Evaluate if a common regex definition can be used to generate modes for Vim, Emacs, and Sublime. Consider writing a script that converts a simple regex syntax file into editor specific formats.
