Dear Guix Hackers,
Currently to install a local package definition, I have to adjust the GUILE_LOAD_PATH by hand:
GUILE_LOAD_PATH=. guix package -e '(@ (mercurial) hg)'
This could be much clearer if the $pwd were in the load path automatically.
Even clearer could be something like overlays as discussed on guix-devel.¹
Examples of usage could be:
# install from an explicit definition file
guix package --file mercurial.scm -i mercurial
# install from a directory with many scheme files: essentially just
# adds the directory and subdirectories to the load path.
guix package --overlay . -i mercurial
With the obvious short forms:
(--file | -f)
(--overlay | -o)
Overlay and file might be used multiple times to adjust the available
packages.
Adding the local path to the package would be a first step, but it
would be unnecessary if there were a way to define additional files
and overlays.
Best wishes,
Arne

As usual, it is a bad idea to include ‘.’ in the search path, because it
makes it easy to unwillingly execute untrusted code.
More generally, ‘GUILE_LOAD_PATH’ is a user environment variable (like
$PATH, $CPATH, etc.), so it’s up to the user, not to Guix, to set it up
correctly.
So I’m closing this bug, but of course, I remain open to discussions on
improving Guix to better support “overlays”.
Thanks!

I now learned, that with guile I can use
guile -L .
which actually does what I need.
Providing this in guix would be consistent with guile and it would make it really easy to select overlays.
Best wishes,
Arne

If this is a ‘-L’ option, then I’d say no. After all, Guix is just
another Guile library, and as such it must not fiddle with the search
path.

Isn’t guix a standalone program?

It's both a library and a standalone program.
If you're using one or more overlays, isn't it easier to set
GUILE_LOAD_PATH in your dot files? I wouldn't want to have to
specify one or more -L arguments every time I use guix.
