On requesting new languages

This is a general answer to requests for adding new languages that appear from time to time in the highlight.js issue tracker and discussion group.

Highlight.js doesn’t have a fundamental plan for implementing languages, instead the project works by accepting language definitions from interested contributors. There are also no rules at the moment forbidding any languages from being added to the library, no matter how obscure or weird.

This means that there’s no point in requesting a new language without providing an implementation for it. If you want to see a particular language included in highlight.js but cannot implement it, the best way to make it happen is to get another developer interested in doing so. Here’s our Language definition guide.
