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.
