hi @kaby76 Can you combine the 3 important grammars? HTML CSS JS

We could merge the grammars but it's not practical yet. The problem is that Antlr4 doesn't have a good way to add different grammars together like this. Symbol names collide, and the lexer rules are all active, which is not what should be done. The plan is to see if we can get either Antlr-ng or Antlr5 to make this easier to do.

Will everything change in antlr5?

Not sure. I have to lobby for a change to do this. Antlr-ng, which is a rewrite of Antlr4 from Java to TypeScript, is coming along nicely. But just without extensions it will be several more months. Antlr5 hasn't had any progress since Feb 2024. If neither have an extension to handle what we want then I will extend the Trash Toolkit to add grammars together but it will not be native in either Antlr or Antlr-ng and it will result in a very large, combined grammar.
