Guix channel for the latest commits of emacs-xyz packages

Channel setup

https://guix.gnu.org/en/manual/devel/en/guix.html#Channels

(channel
 (name 'emacs-latest)
 (url "https://git.sr.ht/~akyle/guix-emacs-latest")
 (introduction
  (make-channel-introduction
   "dd804da433e4e9ccd7408a356cd4f1bec942d28b"
   (openpgp-fingerprint
    "963C 2413 0BD3 BF1B 624C  EF4C 8850 284C 20B8 078D"))))

Usage

(use-modules (gnu packages emacs-xyz)
             (emacs-latest emacs-xyz))

(map emacs-xyz-latest
  (list
   emacs-vterm
   emacs-org
   emacs-magit))

emacs-xyz-latest can be applied to any package in the (gnu packages emacs-xyz) and will apply package-input-rewriting on that package and all its dependencies that appear in the emacs-latest/commits.scm file of this channel. If you only want the latest version of a single package you can use emacs-xyz-latest-only.

Some points of caution!

• Mixing packages from (emacs-latest emacs-xyz) and (gnu packages emacs-xyz) in a profile has the potential to cause conflicts since all emacs package dependencies are propagated.
  • Applying emacs-xyz-latest to every package in a profile should, in principle never result in conflicts.
• The more significantly your guix version differs from the guix version used to generate the packages here, the more likely there are to be issues. There’s some amount of robustness to differences, so that if this channel has packages that your guix does not, it will just ignore them.
• Packages can an will break! fixes.scm attempts to collect overrides to fix the packages, but I will only be maintaining those fixes which affect me, and my responsiveness to updating the fixes will vary.

Updating commits.scm

(use-modules (emacs-latest utils))
(write-latest-emacs-xyz "emacs-latest/commits.scm")

TODO

• Add emacs itself so that I can run the latest upstream version of emacs.
• Put the guix commit used to generate the commits.scm somewhere
• Set up automated daily updates
