How to enable all checks to produce errors without explicitly enabling them one-by-one?

[Coacher]

I prefer to go all-in on checks in new projects. Popular linters like ruff and pylint have simple options to enable all checks (--select=all, --enable=all). I'd like to do the same with pyrefly but was unable to find such option.

Now I have the following workflow:

• find all warn and info checks in source code, because docs don't mention severity of some checks
• add them one by one in pyproject.toml, e.g. deprecated = 'error'

This is cumbersome and difficult to manage as I need to reiterate on every release to catch new checks.

Is there a simpler way to run pyrefly with all warn and info checks promoted to errors, e.g. pyrefly check --error=ALL?

Hey @Coacher! We don't have that yet, but we just added the concept of presets, which seem like a good fit for this case - we can add an "all" preset. I've opened #3328.

@Coacher I was looking for the same feature today, and it seems you can now achieve this with pyrefly check --preset all
