For this website, I currently use NimblePublisher¹ for the content management. By default, it uses Earmark for Markdown and different Makeup packages for syntax highlighting.

Having tried to write a Makeup parser², and being a big fan of Tree-sitter, I was happy to hear about Autumn³ and MDex ⁴. Autumn uses a Rust crate under-the-hood, through Rustler, for Tree-sitter-based syntax highlighting!

It took a few minutes to customise my different content types with NimblePublisher to use a custom HTML converter module⁵.
