guix-edit does not always honour GUIX_PACKAGE_PATH about guix.el

[alezost]

Hm, Works For Me 😕 I use GUIX_PACKAGE_PATH myself and I've never
faced the problem you describe.

Could you evaluate (in M-x ielm, for example) the following:

(guix-package-location "<your-package-name>")

I am using a git checkout of the guix tree in ~/.guix-profile/latest, in case that might influence things.

I suppose you meant ~/.config/guix/latest, right? Do you use it by symlinking it to your git checkout?

Also could you show the value of GUIX_PACKAGE_PATH?
Also did you set guix-directory variable?

`>(guix-package-location "zeal") "gnu/packages/third-party.scm:160:2"` You are correct regarding `~/.config/guix/latest` being symlinked to my git checkout. Also, without me setting anything myself: `>guix-directory "/home/jelle/.config/guix/latest"` And my GUIX_PACKAGE_PATH is: `$ echo $GUIX_PACKAGE_PATH/ /home/jelle/guix-pkgs/` I could easily use the prefix argument and entering my GUIX_PACKAGE_PATH when using guix-edit & co, but that is a bit of a hassle to keep track of. 2017-04-09 20:07 GMT+02:00 Alex Kost <[email protected]>:

(guix-package-location "zeal")
"gnu/packages/third-party.scm:160:2"

OK, so this is the problem. For me, all packages that I have in
GUIX_PACKAGE_PATH have absolute file names, and the packages from Guix
have relative file names ("gnu/packages/..."). So I have:

(guix-package-location "zeal")
"/home/al/config/guix/guix-package-path/gnu/packages/third-party.scm:7:2"

That's why it works for me. And to be honest, I don't know why you have
a relative file name. Could you try the following guile script to check
if it also outputs the relative file name:

(use-modules
 (guix packages)
 (guix utils)
 (gnu packages third-party))

(display (location-file (package-location zeal)))
(newline)

Run it like this:

$ GUILE_LOAD_COMPILED_PATH=/home/jelle/.config/guix/latest GUILE_LOAD_PATH=/home/jelle/guix-pkgs:/home/jelle/.config/guix/latest guile <the-above-script.scm>

Does it output the same file name?

Also I wonder, what if you put your packages just in (third-party)
module (or whatever you'll call it), without "gnu packages" part, I mean
into ~/guix-pkgs/third-party.scm file. What file name do you get in
this case?

[jellelicht]

Running your guile snippet, I get the correct answer:
/home/jelle/guix-pkgs/gnu/packages/third-party.scm

Changing my module to reside in the top level guix-pkgs folder does seem to work. I would still say something somewhere is going wrong, but this workaround is good enough for me. You can close this issue if you want, thanks for the help 👍

EDIT: to recap, placing my custom modules in anything but guix-pkgs/gnu/packages makes them work immediately with guix-edit and related functions.

[alezost]

Hm, interesting.

I see that Guix uses current-source-location Guile procedure (in
(guix packages) module) to define package location. And I wonder why
sometimes it is relative and sometimes absolute.

Anyway, it's not an Emacs-Guix issue (either Guix or Guile).

Closing, thanks.

Hey alezost,

if I am not mistaken, the current guix-devel ML discussion is referring to exactly this issue as I was experiencing it.

Invoking guix edit in a terminal seems to be able to properly resolve any package, so maybe guix.el could do something similar?

EDIT: I guess you are already aware as you were participating in that thread 😜. Me and my reading comprehension...

[alezost]

Yeah, you are right. This is now in the TODO list 😄

[alezost]

I have finally found the time to fix it (by commit f85e1bc) 😊

[jellelicht]

thanks! It makes using emacs for managing guix-related things a lot nicer 😄
