can i tell mypy to warn me on type ignores without error codes, only *# type: ignore[code, ...]* should be accepted

Question

I would like to have all type-ignores with errorcodes # type: ignore[code, ...] and disallow # type: ignore without them.

I checked the docs but could not find what I am looking for.

Is there any option that allows me to do that? I could write my own script to do that, but if mypy can do that I would prefer that.

Something like warn_type_ignore_without_errorcode = True?

This has been added from mypy 0.40 with the ignore-without-code check. Enable it in-code with:

# mypy: enable-error-code ignore-without-code

Or add it to your pyproject.toml file with:

[tool.mypy]
enable_error_code = "ignore-without-code"

Or add it to your mypy.ini file with:

[mypy]
enable_error_code = ignore-without-code
