Hello Guix,
I would like to bring up for debate the convention the project has of
vertically aligning the record definitions. While I agree it lead to
visually pleasing code, I also leads to significantly bloated diffs.
While some amount of noise in diffs is expected in any lisp language
(the trailing `)'), the vertical aligning makes it worse. It (in my
opinion) complicates both reviewing and re-basing (due to merge
conflicts).
For example, take this patch I sent today. It adds *a single field* to
the record. However the patch (that someone needs to review and make
sure is correct) looks like this:

I would like to hear what people who review lot of patches think about
this. Does it make your life worse? Does it not matter? Or does it
even help you in some way?
Thank you for your time and have a nice day,
Tomas

I don't think that's a project convention. It's more like it's a
convention of some individual in the projects :-). At least I don't
follow it, except sometimes when touching a piece of code already
indented that way.

I agree it's a bit tedious, both manually and also in diffs. My
personal preference is to leave just one space between the field name
and the value, that also holds for variable bounds in lets, etc., to
avoid the problem (at the cost of some visual clarity, I guess).
One day maybe we'll have a general tool like 'scheme-fmt' to run on a
file save hook that'd fix the format question for good, like Python has
with 'black' or 'ruff', etc. I have on mind to work on such a tool, but
it's low in the list.

FWIW, Im slowly cobbling together some parsing-expression-grammars for
Guix package definitions.
Im doing it in the Lisp TXR atm but Im going to create a hybrid approach
with Prolog to make it more general.
In addition to outputting a unified formatting, Im planning on altering
descriptions so that that that content is outputted in the format
Texinfo.
Please dont expect anything soon but should anybody start any other
initiative then I may possibly some useful assets or details by then.
Kind regards,
Jonathan

Sounds neat/useful!

I agree it makes for a more bloated diff, but it does make it easier to
read when the indentation doesn't change between each field. What if it
were formatted like this? No gratuitous white space changes for
formatting and more room for code and comments since it's not smushed on
the right side of the screen.
