Developers in the Elixir community have been trying to get Syntax Highlighting support for the Elixir Language on Stack Overflow and other Stack Exchange websites since 2013:

But the latest build of Stackoverflow's prettify.js still does not have Elixir support.

At first I thought it was because of the incorrect language name on google-code-prettify, so I sent in a PR to rename it, but on rechecking the PR['registerLangHandler'] statements in the build, I couldn't find anything for ex either.

I feel like we're missing something very obvious here. How do we get SO/SE to include a language in its prettify.js builds when there already is support for the language in Google Code Prettify?

  • Hey @SonictheAnonymousHedgehog, do you have any insights/pointers on how we could speed the process up? Because I feel like this request has been lost in the pile again.

    This seems to have fallen between the cracks again? Elixir is a small community on SO but there's enough activity to see questions asked on a daily basis. People have obviously been (mis)using ruby syntax highlighting in the meantime but if there's a specific syntax highlighting available upstream for Elixir it seems it should be implemented. In comparison, Erlang has syntax highlighting and it has a similar number of questions on SO. It'd be great to see this resolved. Thanks! Jun 23, 2020 at 8:51

We've officially switched to highlight.js network-wide. See the announcement post for more details.

  • Does this mean that SE supports auto Elixir highlighting now (or will soon)?
