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.

The author of the library probably has learned, the hard way many many lessons (and probably also decided to prioritize some of the requested issues / feature requests along the way).
The above is not meant as a ding on the project itself and I am sure it is used successfully by many people. The point here is that your claim that you can easily write a csv parser in 200 lines of code does not hold water. It's anything but easy and you should use a battle tested library and not reinvent the wheel.
This isn't my code, but gives you an idea of the complexity involved. But don't reimplement what you don't need to.
