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.

How do you start your own programming language?
Here's a javascript library that lets you generate your own language that compiles to Javascript. https://pegjs.org/ It's a compiler generator. You can either use the command line tool and feed it your grammar (You have to write that) and use the generated parser.js which can then run your program, or use peg.js as a dependency and generate your parser at run time before feeding it your program.

The library they're having trouble with is the most common parser generator in javascript, peg.js, which has about 80% of the market

PEG Parsers: sometimes more appropriate than Regex
In past blog posts, where I've written about PEG, I've used Parsimonious in Python, such as three of my solutions to the 2020 Advent Of Code challenges (here, (here)[https://dev.to/meseta/advent-of-code-day-18-finally-using-peg-grammar-in-python-in-the-way-it-s-supposed-to-3253], and (here)[https://dev.to/meseta/advent-of-code-day-19-abusing-peg-grammar-in-python-the-way-it-s-not-supposed-to-2beg]). This time, because the rest of the website is javascript, I will be using PEG.js instead to avoid adding an extra programming language to the codebase.

Formal Logic Rules for a computer-assisted RPG
Update: I started writing a grammar for this language in PEG using PEG.js. This was super fun, I'll take a stab at an interpreter next, that should be much harder.

I'd like to ask you guys a question, how or in what way is a Programming Language made?
I was going to post the same thing. This really helped me understand the concepts better back in the day. They also have examples for some popular languages on their github: https://github.com/pegjs/pegjs/tree/master/examples
