Convert from TextMate grammar

[goodmind]

Is there converters from textmate grammars or I need to rewrite grammar manually?

[isagalaev]

No, there's no converter. Mostly due to our peculiar syntax and also different philosophies in what gets highlighted. Look at Language definition guide and Style guide.

[goodmind]

@isagalaev well, how to do something like beginCaptures?

[isagalaev]

This is something that highlight.js doesn't have, and what makes a generic converter impossible :-)

The more useful answer depends on what you're trying to achieve. Sometimes there are highlight.js-specific solutions, sometimes we just straight up don't want to highlight something. So please provide an example!

[goodmind]

I have this grammar and want to convert it into highlight.js one: https://github.com/goodmind/language-typelanguage/blob/master/grammars/typelanguage.tmLanguage.json

And I have combinator-declaration-without-hash with begin regex (([_$\\w]+)(\\b\\.))?([_$\\w]*)(\\b#)([[:alpha:][:alnum:]]*)\\s*

And I want to highlight captures inside it:

"2": {
    "name": "meta.definition.combinator.tl variable.other.tl"
},
"4": {
    "name": "meta.definition.combinator.tl variable.other.tl"
},
"5": {
    "name": "storage.type.tl"
},
"6": {
    "name": "storage.type.tl"
}

Example of file that I want to highlight: https://github.com/goodmind/language-typelanguage/blob/master/examples/scheme.tl

@isagalaev any thoughts?

[stevepeak]

@goodmind did you end up solving this problem? I have the same one.

[goodmind]

@stevepeak I didn't

[stevepeak]

@goodmind Would you be interested in helping contribute to an open source package that does this?

[goodmind]

@stevepeak yes, but I think it's impossible because TextMate uses oniguruma regexp engine (doesn't work in browser at least now)

[stevepeak]

Oh... good to know. I'll ping you when we look more into this.

[joshgoebel]

If you all made any progress with a general purpose converted I'd be curious.

[joshgoebel]

Closing as this is asked and answered. Still if you make any progress I'd love to hear about it. :)
