Ohm: A library and language for building parsers, interpreters, compilers, etc.
How does this compare with Chevrotain[1]?
More specifically, can I build lexers with Ohm? Can it generate a syntax diagram from a grammar?

Why are you building a programming language?
I don't think I'll have time to make one any time soon, unfortunately. My original plan was to write a compiler in TypeScript using Chevrotain, and see if it's possible to compile down to TypeScript's AST and feed that into its own compiler programmatically. Basically piggybacking on Microsoft's hard work (work smart, not hard). I don't know if it's possible, but it's what I'd try first.
