Fix unexpected whitespace removal outside line range by limwz01 · Pull Request #1102 · google/yapf

limwz01 · 2023-06-06T02:26:47Z

save the whitespace prefix in the pytree node even for those occurring with comments
disable the comment splicer's removal of trailing whitespace
add back the whitespace before emitting unformatted line
remove trailing whitespace in comments for enabled lines later when printing

TODO:

extensive testing is necessary as this method is like a hack
this still will remove trailing whitespace in line just before line range and will ignore trailing whitespace in last line of line range

Could you give an example of what this is fixing?

limwz01 · 2023-10-25T17:28:26Z

The example is in the linked issue.

After a long while of using this with only the problems mentioned in my first post, I've found a further problem that occurs with the following:

def main():
    if 1:
        if 1:
            pass

        # extra
        elif 1:
            pass
    pass

Applying the modified yapf on anywhere except including the extra comment line, we will get extra trailing space on the line before the extra comment line. I've not figured out the bug yet.

This needs testcases.

Add a default prefix='' so you only have to pass it in when it's not empty.
