Guix completion in Emacs

Guix completion in Emacs

[Kyle Andrews]

Hello Everyone,

I am unable to conditional tab completion of Guix commands when in
shell-mode or eshell-mode in Emacs. In other words, I can tab-complete
the major modules e.g. ~guix package~, but cannot tab complete
~--arguments~ to them. When I try I see an error:

  guix-geiser-eval: Error in evaluating guile expression: ice-9/boot-9.scm:1669:16: In procedure raise-exception:
  error: help-string: unbound variable

Certainly this stuff isn't broken for everyone, is it?

This works for me.

I'm getting the same error. On a foreign distro with emacs-next.

It works on and off for me, sometimes with the same error.
I haven't figured out yet how to reproduce this issue reliably.

Part of the reason it may have been breaking for me was that I was
placing an additional git checkout of guix on my guile %load-path. I
don't remember why I thought I might need to do that.

If you want to hack Guix from Geiser, you need to add the checkout to
your %load-path.
