As part of building an emacs local CI (ELCI lol) for myself, I've setup some tooling others might find interesting.
This page generates a commit in near-real-time, updated when someone pushes to emacs.git on savannah: https://u.bru.st/?#emacs-dev
You can get a single property like this: https://u.bru.st/last-rev.pl/?project=emacs&property=revision
Finally, you can also view the raw JSONL FIFO used by last-rev.pl: https://u.bru.st/emacs.jsonl
Sources should be all, or very nearly all, somewhere on my sr.ht GPL or APGL licensed but I'm afraid I've lots to do shifting things around so they make much sense from "the outside". Trying to setup all of this just from sources and my notes so far is probably not great fun. https://git.sr.ht/~mplscorwin/
FTR, this is very brittle; please be gentle in your experimentation and do shout if you see something I might should fix. Same handle on libera.chat IRC is the fastest way to reach me when I'm reachable.
