A web interface (actually two web interfaces!) are available to browse issues:
To view discussions related to issue number n, go to
Mumi also comes with a command-line interface that can be used to search existing issues, open new issues and send patches. You do not need to use Emacs to use the mumi command-line client. You interact with it only on the command-line.
To use the mumi command-line interface, navigate to a local clone of the Guix git repository, and drop into a shell with mumi, git and git:send-email installed.
$ cd guix ~/guix$ guix shell mumi git git:send-email
To search for issues, say all open issues about "zig", run
~/guix [env]$ mumi search zig is:open #60889 Add zig-build-system opened on 17 Jan 17:37 Z by Ekaitz Zarraga #61036 [PATCH 0/3] Update zig to 0.10.1 opened on 24 Jan 09:42 Z by Efraim Flashner #39136 [PATCH] gnu: services: Add endlessh. opened on 14 Jan 2020 21:21 by Nicol? Balzarotti #60424 [PATCH] gnu: Add python-online-judge-tools opened on 30 Dec 2022 07:03 by gemmaro #45601 [PATCH 0/6] vlang 0.2 update opened on 1 Jan 2021 19:23 by Ryan Prior
Pick an issue and make it the "current" issue.
~/guix [env]$ mumi current 61036 #61036 [PATCH 0/3] Update zig to 0.10.1 opened on 24 Jan 09:42 Z by Efraim Flashner
Once an issue is the current issue, you can easily create and send patches to it using
~/guix [env]$ git format-patch origin/master ~/guix [env]$ mumi send-email foo.patch bar.patch
Note that you do not have to pass in ‘--to’ or ‘--cc’ arguments to
mumi send-email will put them in
correctly when sending the patches.
To open a new issue, run
~/guix [env]$ mumi new
and send patches
~/guix [env]$ mumi send-email foo.patch bar.patch
mumi send-email is really a wrapper around
send-email that automates away all the nitty-gritty of sending patches. It
uses the current issue state to automatically figure out the correct
‘To’ address to send to, other participants to ‘Cc’, headers to
Also note that, unlike
works perfectly well with single and multiple patches alike. It automates
away the debbugs dance of sending the first patch, waiting for a response
from debbugs and sending the remaining patches. It does so by sending the
first patch, polling the server for a response, and then sending the
remaining patches. This polling can unfortunately take a few minutes. So,
please be patient.
If you use Emacs, you may find it more convenient to interact with issues using debbugs.el, which you can install with:
guix install emacs-debbugs
For example, to list all open issues on
C-u M-x debbugs-gnu RET RET guix-patches RET n y
Veja Debbugs User Guide, for more information on this nifty tool!
The web interface at https://issues.guix.gnu.org is powered by Mumi, a nice piece of software written in Guile, and you can help! See https://git.elephly.net/gitweb.cgi?p=software/mumi.git.
