Don't break lines with inline comment?

[Lucianod28]

Is there a way to prevent ruff from breaking lines that are over the length limit because of an inline comment? For example:

if some_check or other1 or other2 or other3:  # inline comment that makes the line exceed 100 characters

becomes

if (
    some_check or other1 or other2 or other3
):  # inline comment that makes the line exceed 100 characters

I would prefer for it to be

# inline comment that makes the line exceed 100 characters
if some_check or other1 or other2 or other3:

I assume that's not possible, but is there a way to configure Ruff to simply not break long lines containing inline comments? I wouldn't mind manually breaking the line in that case, just like when you have a comment that's too long.

I don't believe there's an existing option for this. There's a recent related issue in #20641, albeit for a more specific use case.

Yeah, there's no such option. Ruff's formatter is intentionally not very opinionated when it comes to comment placement because there are many different styles. The other challenge is some comments have semantic meanings where it isn't safe to move them too far. For example, making a noqa a leading comment would change what it suppresses (it might even become a block suppression comment).

The recommendation here is that the author moves the comment where it makes more sense. This can be any of the following options:

If the comment applies to the entire if

# inline comment that makes the line exceed 100 characters
if some_check or other1 or other2 or other3:

if the comment applies to one specific check

if (
	# inline comment that makes the line exceed 100 characters
	some_check 
	or other1 
	or other2 
	or other3
):

# or 
if (
	# inline comment that makes the line exceed 100 characters
	some_check or other1 or other2 or other3
):
