Does apheleia support formatting of narrowed buffer?

[dvzubarev]

Hi, thank you for this package.
I use python black formatter and one day I wanted to edit narrowed region.

class A:
    pass

|class B:
    pass|

class C:
    pass

Select the code inside | call M-x narrow-to-region - you will see only:

class B:
    pass

After editing and saving the narrowed buffer - the code disappears.
Call M-x widen and the content of the buffer will be

class A:
    pass



class C:
    pass

Hey @dvzubarev, sorry for the delayed response. At the moment this isn't supported, but it's definitely a feature I would be happy to see incorporated. I don't think it would be tremendously difficult, we probably just need to be a little more careful with how the formatting code interacts with the current buffer restriction. There's also of course the restriction that for formatters that require operating on the original file in-place in the project, we will end up formatting the entire buffer whether it's narrowed or not.

Thank you for your response. FWIW I remember that I made quick experiments with replace-buffer-contents (#38) and it seems to work fine with narrowed buffers.
