This puzzles me. If I use etags I can get *xref* to show ...

/home/g1/src/guix/test-tmp/store/ywpd8i2s87fzmzfpl2h96m949p7rwmcd-guile-bootstrap-2.0/share/guile/2.0/ice-9/curried-definitions.scm

Isn't one of these what I want to look at?

Thank you for helping me to get "C-c . u", "M-." working.  For others
that may care, here are fixes I needed:


Problem:

emacs-guix development mode (C-c . _) functions don't work:

Fix: add in emacs `init ...

(add-hook 'scheme-mode-hook 'guixlevell-mode)


Problem:

'C-c . u' is horribly slow and 'M-.' produces  ...

geiser-ediot-symbol-at-point: Couldn’t find edit location for ’define-module’

As you explained off-list ...

Fix: remove guile from user and/or system profiles!


Problem:

'C-c . u' is not so horribly slow and 'M-.' produces ....

geiser-ediot-symbol-at-point: Couldn’t find edit location for ’define-module’

Fix: remove ...

(with-eval-after-load 'geiser-guile
   (add-to-list 'geiser-guile-load-path "~/src/guix"))

...  from emacs init. Add this to .bash_profile ...

export GUILE_LOAD_PATH="$HOME/src/guix${GUILE_LOAD_PATH:+:}$GUILE_LOAD_PATH"
export GUILE_LOAD_COMPILED_PATH="$HOME/src/guix${GUILE_LOAD_COMPILED_PATH:+:}$GUILE_LOAD_COMPILED_PATH"
