For implementing any useful feature in the Language Server, we need a parser so that analyze the code and serve completions lists or go to definitions.
We could use something like ANTRL, so we can generate a parser using only the grammar, which is already specified. The parser could be used with Typescript and Go, so we can choose the language we prefer.
Hare uses an LL(1) grammar, so ANTLR seems to be a good fit.
While ANTLR is written in Java, once a parser is generated we only need a runtime library and the generated code, so no hard dependency in Java is needed.
Once we have a working prototype for the whole Language Server, we can work towards using our own implementation or even switch languages entirely to Hare itself. That's in the future, though.
