This PR introduces a pre-commit hook of tombi to standardize the toml format.

Do you also wanna check this in make lint and make format?

Good idea 😄

I have another proposal in mind.

Currently, we have pre-commit hooks configured for:

• ruff format
• ruff check
• ty check
• mypy

These checks are also included in make lint, which is why we skip them in CI whenever prek is instantiated.

Given this setup, would it make sense to consolidate the workflow and reduce the maintenance overhead by relying on a single entry point? If prek run -a is capable of handling all formatting, linting, and related checks consistently, we may no longer need separate make lint and make format targets.

What are your thoughts on this approach?

[juanitorduz]

I agree! In most of my other projects, I simply use https://github.com/pre-commit/action :)

What's the setup that makes it easier to contribute without having to worry about toml/ty etc. dependency? I think we want to have minimal requirement for formatting. The rest is optional.

I personally do not think there is an absolute best way, and its more about opinions XD

My preference (this is an opinion, not a fact) is towards pre-commit hooks. Again, no strong preferences and the Make command also works fine.

In my opinion, pre-commit hooks are the better approach. We only need to install pre-commit/prek, and it can manage all additional dependencies automatically. The only maintenance overhead is periodically updating the hooks to their latest versions, which can also be automated using a GitHub bot.

This is a great point! We have pre-commit update PRs as pymc-labs/pymc-marketing#2506

It needs minimal configuration:

@juanitorduz @fehiepsi should we merge this PR? 😄

[fehiepsi]

I guess so. Just to confirm, do I need to install all those hooks for the dev workflow? All I want is to use ruff to format the scripts and make a commit without worrying about those .pre-commit-config.yaml‎ configurations, which I'm not familiar with.
