Hi, right now I'm just trying, during my lunchbreaks, to fix the code that is 
already written. But I keep having to use my lunch breaks for other things, 
like vehicle maintenance, so progress has been slow.

https://git.savannah.gnu.org/git/guix/emacs-guix.git/

One of the interfaces emacs-guix provides is a magit-popup interface to all the 
guix commands, which it generates by parsing the "guix --help" output, along 
with Improver code to improve handling of some of the options. That was broke 
(for years...?) because the regex expected three spaces before a command 
description, whereas now there is four spaces. I submitted a patch for that. 
What is the old saying? Solve a problem with a regular expression, and now you 
have two problems. :) But the regular expressions are written in that nice rx 
notation, so that helps a lot.

Emacs-guix uses magit-popup, the predecessor of Transient.
