we switched to a new linting setup on our massive app of over 5k files. we are using biome + eslint (for missing rules in biome). after i looked at this PR, think ast-grep is a nice tool to write custom linting setup and it should be close to the speed of biome if i'm not wrong.

Thanks for your interest in ast-grep! To be fair, ast-grep can not be close enough to the speed of biome. ast-grep uses a general parser so biome/swc/oxc can beat it easily. That said, ast-grep's native parser can still be on par with eslint. And it's using multiple cores so it can be faster.

I believe 5K files should be linted under 3 seconds on the GitHub CI machine.😀 I would be more than happy if you could share the number and tag me for that post!

i'll try it out for few of our custom eslint rules over this weekend. will inform when I'm done. well I've already used it for some codemods while migrating from next-translate to lingui/macros. it was super useful, particularly in determining scope when multiple `t` tags were used and aliased.

nice job on making it. only sad thing is current LLMs are not that proficient in ast-grep compared to jscodeshift, which makes it slight harder to go learn stuff from docs. but the docs are nice tbh 🚀

In case you need to know the limitation of ast-grep, this FAQ should help (to probably save you some time ahead)
