Pandoc CSS for Hakyll

Drop-in CSS for code highlighting in Hakyll. Extracted from pandoc (skylighting) thanks to this blog.

Long story

Hakyll is a Haskell library for generating static sites which uses Pandoc for code syntax highlighting. But Hakyll by default does not include any CSS for highlighting your code. So even if pandoc adds CSS classes to the generated HTML, you won't be able to see any highlighting. This is probably because Hakyll wants users to have control of how to style their blog.

But the problem is CSS for pandoc is not easily available that is when I stumbled upon this blogpost.

Interstingly pandoc uses Skylighting internally which comes bundled with a bunch of themes. But those themes are not readily available as CSS files in the repo - they are generated from code. That blogpost explained how to generate CSS from Skylighting. So I went ahead and generated them for all available themes! 🎉
