Hi!

A couple of months ago I stumbled upon this awesome-looking guide
<https://rednosehacker.com/combo-guix-shell-emacs-envrc-el> and today I
finally found the time to setup direnv and emacs-envrc with Guix for my
development projects.  Really should have done this sooner, it's a huge
step-up from M-x guix-set-emacs-environment (or in avoiding to do that
run make in the shell and lookup line numbers manually -- why does ffap
not respect GNU-style error messages, btw?).

Most everything worked...except for Guix; as Guix git does not support
`guix shell' ootb; you really need your own local hack or have to type
something like "guix shell -D guix".

In the attached patch I share my local hack `maintenance.scm', which
allows this generalized .envrc

--8<---------------cut here---------------start------------->8---
eval $(guix shell --search-paths)
if test -d doc; then
   export INFOPATH="$PWD/doc${INFOPATH:+:}$INFOPATH"
fi
if test -f pre-inst-env; then
    source pre-inst-env ""
else
    export GUILE_LOAD_PATH="$PWD${GUILE_LOAD_PATH:+:}$GUILE_LOAD_PATH"
    export GUILE_LOAD_COMPILED_PATH="$PWD${GUILE_LOAD_COMPILED_PATH:+:}$GUILE_LOAD_COMPILED_PATH"
fi
--8<---------------cut here---------------end--------------->8---

to also work for Guix.

Greetings,
Janneke
