Hi, I'm trying to troubleshoot some bugs in the venerable emacs-guix package, which you've probably heard of. In its default configuration, emacs-guix uses geiser to set up one Guile REPL (*Guix REPL*) to handle various guix operations, and tells it to --listen on a domain socket; and then it uses some comint functions to connect to the domain socket, to provide another Guile REPL (*Guix Internal REPL*) which it uses for various other guix operations while the main REPL is busy.
In guix bug#73462, I figured out that the bug was caused by, for some unknown reason, (guix gexp) reader syntax was working in the main REPL (*Guix REPL*) but not in the REPL that was over the socket (*Guix Internal REPL*). A work around is available, which is to run an extra ",re (guix gexp)" in the internal REPL buffer, and then after that it works fine, but I don't understand why that should be necessary. Can somebody help me figure if this is some kind of bug in Guile, or a different issue...? This can be reproduced this one my system command line with the following commands. Of course, you would need to adjust for your own paths. On one terminal: ``` shell christopher@theoden ~$ /gnu/store/g1fhmjs2mh8a0djfnyaha49ihb5cmkas-profile/bin/guile --no-auto-compile -L /home/christopher/Repos/emacs-guix/scheme -C /home/christopher/Repos/emacs-guix/scheme -L /home/christopher/.config/guix/current/share/guile/site/3.0 -C /home/christopher/.config/guix/current/lib/guile/3.0/site-ccache --listen=/tmp/test-socket ``` Then on another terminal: ```shell christopher@theoden /gnu/store/pg7s74p1p3bf2k848xy4j0x8dcqv248l-netcat-openbsd-1.219-1/bin$ ./nc -U /tmp/test-socket GNU Guile 3.0.9 Copyright (C) 1995-2023 Free Software Foundation, Inc.
