Hi!
Just subscribed to help-guix because of a request on IRC, so hoping that
OP is subscribed here, or someone can notify them.
I have an ugly hack to switch emacs to a profile or environment. It
parses the <profile>/etc/profile script...using MANIFEST or
`--search-paths' would be much nicer...
Anyway, I'm using some named profiles, eg
~/.config/guix/mes
and when starting work on mes i do
M-x guix-switch-profile RET ~/.config/guix/mes RET
similar for other projects I work on.
A real solution would be nice...
HTH, janneke

(defun guix-switch-profile (&optional profile)
"reset Emacs' environment by snarfing PROFILE/etc/profile"
(defun matches-in-string (regexp string)
"return a list of matches of REGEXP in STRING."
(let ((matches))
(save-match-data
(string-match "^" "")
(while (string-match regexp string (match-end 0))
(push (or (match-string 1 string) (match-string 0 string)) matches)))
matches))
(interactive "fprofile: ")
(let* ((output (shell-command-to-string (concat "GUIX_PROFILE= /bin/sh -x "
profile "/etc/profile")))
(exports (matches-in-string "^[+] export \\(.*\\)" output)))
(mapcar (lambda (line) (apply #'setenv (split-string line "="))) exports )))
