Respect spacing around colons and assigments

[nuno-andre]

Hi, everyone!

I use to align types and some assignments as follows:

@dataclass
class Example:
    an_attr:      int
    another_attr: str | None
    whatever:     dict[str, str]


class Colors(IntEnum):
    BLACK  = 0
    RED    = 1
    YELLOW = 2

I have searched the documentation and this repo, but I can't find a way to make ruff respect this spacing. Is there any way?

Thanks!

Hi! Our formatter does not support this. There's a similar discussion about alignment of trailing comments at #7684 that you may find interesting. I'd recommend disabling formatting in these sections for now.

There are also some previous discussions over on Black, which we are currently aiming for compatibility with:

• Aligning Equal Signs psf/black#1480
• Allow aligning assignments using multiple spaces before = psf/black#3654

Thank you for the references! I only meant to ignore formatting around colons and assignments, but yeah, vertical alignment would be a dream.
