Using emacs library with guix environment

Using emacs library with guix environment

[jgart]

Hi,

I'm trying to use emacs-commander with guix environment on a foreign distro.

I'm only able to properly source the library into the environment if I run 
the following:

`guix environment emacs-commander --ad-hoc emacs-commander`

Why do I have to provide emacs-commander twice to the environment command?

I tested only using --ad-hoc or without and none of those work.

I'm only able to properly source emacs-commander when I include it twice as in
the above command.

Could someone explain the reason for this to me?

Any help is much appreciated.

all best,

jgart

Hello !

I'm not sure what the problem is with this particular package, but:
guix environment emacs-commander

will create an env with all you need to BUILD emacs-commander

while

guix environment --ad-hoc emacs-commander

will create an env in which emacs-commander is installed.

Now, if guix environment --ad-hoc emacs-commander doesnt work, it may
mean that one of the native-input of emacs-commander should be an input
or a propagated-input instead. That would explain why

guix environment emacs-commander --ad-hoc emacs-commander

works: because it installs this native-input in the env as well.

I hope this makes sense, if not please ask away.

Cheers,

Edouard.

I believe the key package that the first emacs-commander (the one before
--ad-hoc) brings in is emacs along with its corresponding EMACSLOADPATH.

Notice that

  $ guix environment --pure --ad-hoc bash emacs-commander -- sh -c 'echo $EMACSLOADPATH'

outputs nothing.  Now if emacs is added as an ad-hoc package:

  $ guix environment --pure --ad-hoc bash emacs-commander emacs -- sh -c 'echo $EMACSLOADPATH'
  /gnu/store/qg6rsw6w587aykln2dzssr43nl6jq1a1-profile/share/emacs/site-lisp

Or another test, dropping --pure to be closer to your initial snippet:

  $ guix environment --ad-hoc emacs-commander -- \
    emacs -Q --batch --eval '(print (locate-library "commander"))'
  nil

  # add emacs as ad-hoc package
  $ guix environment --ad-hoc emacs-commander emacs -- \
    emacs -Q --batch --eval '(print (locate-library "commander"))'
  "/gnu/store/kr9cnw5c9nydiilb25w3q5bnp5c1zvca-emacs-commander-0.7.0/share/emacs/site-lisp/commander-0.7.0/commander.elc"
