I always feel that when saying lex/yacc style tools, it comes with a lot of preconceived notions that using the tools involves a slow development cycle with code gen + compilation steps.

What drew me to the grmtools (eventually contributing to it) was that you can evaluate grammars basically like an interpreter without going through that compilation process. Leading to a fairly quick turnaround times during language development process.

I hope this year I can work on porting my grmtools based LSP to browser/wasm.
