I asked this question 5 years ago, and got the very helpful answer that I could clone the repository at
https://github.com/gohugoio/hugoThemes.git
and then search through the theme.toml files using find and egrep. However, that site has been replaced with
https://github.com/gohugoio/hugoThemesSiteBuilder
which doesn’t actually contain all the information, more a listing of the git repositories of the current themes. What I want is some way to find which sites, for example, support mathjax (for mathematics), or abcjs (for music notation). This is hard to do on the hugo themes site. I’d also want to find, if possible, if there are any forks of older themes. For example, the story theme is no longer maintained as its original developer “encourages forking”. How do I find if there’s an actively maintained fork?
Thanks very much!
