Utils for working with Lezer grammars.

Example

In your grammar package, add bin/chk containing this:

#!/usr/bin/env node
import { mainChk } from 'lezer-utils'
import { lr } from '../dist/index.js'
mainChk(lr)

then use chk to test the parser against a dir:

$ ~/src/codemirror-lang-zig/bin/chk -r ~/src/zig/src/link/tapi/
