Not sure what you mean by this. I have pre-commit set up to do linting in several different projects, and even have it running multiple differently-configured lint jobs in the same repo.
I don’t mean using lints, I mean writing custom ones. Say you have a custom lint you want to use but it only will ever be used for that specific project. You can’t just put the lint code in a subdirectory. It has to go in a separate repo.
Pre-commit absolutely does take care of setting up venvs with needed dependencies.
Again I think you might be misunderstanding. It will install pylint fine, but if your project does e.g. import yaml, it’s not going to set up a venv and install pyyaml for you.

You can run locally defined hooks with pre-commit, just define them in the repo: local section of the .pre-commit-config.yaml, and have it run a bash/python/whatever script or something that invokes your custom linting, wherever it lives in your file structure.

Yeah I misspoke/misremembered there. For Python based stuff, it uses the currently active virtualenv or your global python install, so it relies on you installing your own dependencies. Which isn’t really that big a deal imo, because you need to install those dependencies to run/debug/test locally anyways.

Sounds like you’re just googling it rather than actually speaking from experience. Suppose I have written a Python lint and it’s in my ci/lints/foo folder. How do I tell pre-commit that? (Hint: you can’t)

For small Python projects, maybe not. The project I’m working on has multiple sub-projects and those each have their own venvs, pyproject.tomls, etc.

Like I said, I’ve used pre-commit for multiple years now. If you can run your lints from a command line, you can configure pre-commit to run them.

Monorepos definitely make things a bit trickier, but again, you absolutely can write a local pre-commit hook that runs a bash command or script that 1.) activates the necessary venv and 2.) runs the lint command. I know this because I’ve done it, multiple times.
