How do i make a custom language?

[elgansayer]

I realise it's not an issue.

I am trying to make a custom language. how would i go about doing that?

Commenting and making Mode() available would be really helpful.,

I guess you'd need to create a custom highlight JS mode https://github.com/git-touch/highlight.dart It's already available, go check out the custom_code_box in the examples!
