Hi! The best patch-tracking candidate I’ve seen so far is “patches”, written by/for the QEMU people (the ‘patches’ package in Guix.)
https://www.gnu.org/software/guix/packages/#patches I think it has everything most of us want, including an Emacs interface. The main “difficulty” is setting it up on a machine where it can serve those patches.json files over HTTP based on the mailing list archive (which could be synced from <ftp://lists.gnu.org/guix-devel/>) and Git repo. There’s a README in the the source tree that explains the details: https://github.com/aliguori/patches/blob/master/README-server.md Would someone like to set it up somewhere and share a recipe? I’d be happy to beta-test it as soon as it’s available! :-) Ludo’.
