Grammar Requests

Please Note: Highlight.js doesn't have a fundamental plan for implementing languages, instead the project works by interested contributors writing and publishing their own language definitions.

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 supported by highlight.js but cannot implement it, the best way to make it happen is to get another developer interested in doing so.

Currently the Highlight.js repo is closed to new language definitions due to a lack of maintainers time to review, maintain, and respond to issues. It's recommended that new language definitions be created in their own repositories and we have some examples you can look at:
