With Emacs 28 and new versions of Geiser (such as the one in Guix) I
highly recommend enabling per-project REPLs. By setting
geiser-repl-per-project-p to 't', commands like M-x run-guile and C-c
C-a will open/switch to a REPL associated with the current project as
determined by project.el. This is useful for when you are working on
multiple projects at once as it makes it harder to mix up REPLs, but
Geiser also automatically inserts the project root directory into
Guile's load path. When combined with emacs-direnv, emacs-envrc,
emacs-buffer-env, or emacs-guix-shell, the Guile binary that Geiser
uses when launching a per-project REPL will be the one from the 'guix
shell' profile, and it will honor the
GUILE_LOAD_PATH/GUILE_LOAD_COMPILED_PATH settings. So now, at long
last, my Geiser REPLs automatically use the proper build of Guile, it
can load the external libraries my project depends on, *and* it can
load my local project modules. I'm quite happy with this setup.
Maybe I could write a blog post specifically about setting up a Guile
development environment with Guix and include all these details.
