antlr4 syntax.

See original GitHub issue

🐛 Bug Report

While antlr4 is a supported syntax in prism, it does not look like it’s supported in D2. This is likely due to the syntax not being included with D2. If this is the case, what is the best course of action?

To Reproduce

Enter this antlr4 snippet and use antlr4 or g4 per the prism instructions as the language:

grammar JSON;

json
   : value
   ;

obj
   : '{' pair (',' pair)* '}'
   | '{' '}'
   ;

Reading the docs, swizzle is to be used when I add my own language support. I am trying to use an existing language supported by prism here.

If you want to add highlighting for languages not yet supported by Prism, you can swizzle prism-include-languages

It is enough, not sure if Prism somehow brings the language syntax at runtime or if it’s comes packages with all of them after all. it’s small enough (1.17K).
