Awesome @mertyildiran, exactly what I was looking for 👍
Would be great to this it merged and release.

Although it works great for my use case, shouldn't it be syntaxes: refractor.RefractorSyntax[]? So that multiple syntaxes could be registered?

Tested on a personal project, works great 💯

Is this repo still maintained @katydecorah @davidtheclark? (Sorry I'm not really sure who to mention)

[mertyildiran]

@hugocaillard I thought you were one of the maintainers.

[davidtheclark]

I'd recommend forking the library if you'd like to move it forward.

[mertyildiran]

@davidtheclark yeah, I know but this is a dependency of a dependency for me. So I need to fork two libraries which I don't want to do that. See uiwjs/react-textarea-code-editor#85

I'll have to do that only if I cannot made them merged in a reasonable time.

@katydecorah any update on this PR?

[katydecorah]

@mertyildiran I no longer work at Mapbox and unfortunately I'm not sure who will maintain this repository moving forward.

[mertyildiran]

@katydecorah I understand. Thank you so much!
