The primary benefit would be much faster startup/run on larger projects.

would you like to write a language: bun ? https://github.com/pre-commit/pre-commit/blob/main/CONTRIBUTING.md#adding-support-for-a-new-hook-language

[gaborbernat]

I'll try if I get to it, no promises 😆 would it be possible to convince https://github.com/pre-commit/mirrors-prettier#prettier-mirror to use bun without needing changes to that repo, though?

[asottile]

yeah in theory you'd set language: bun and it should just work assuming we make language: bun as compatible with language: node as possible

[gaborbernat]

So it would be:

-   repo: https://github.com/pre-commit/mirrors-prettier
    language: bun
    rev: ''  # Use the sha / tag you want to point at
    hooks:
    -   id: prettier

?

close -- language is defined at the hook level not a the repo level
