[ANN] Emacs-Guix 0.5.1

[ANN] Emacs-Guix 0.5.1

[Alex Kost]

Hello, Emacs-Guix (Emacs interface for GNU Guix) version 0.5.1 has been
released.  If you are not familiar with it yet, you may try it with:
‘guix package -i emacs-guix’ and "M-x guix".

Summary of the new features:

* M-x guix

  This is the *new* "M-x guix" which is a popup interface for the rest
  Emacs-Guix commands.  You may find a screenshot of this popup window
  at <https://emacs-guix.gitlab.io/website/images/screenshots/popup.png>.

  The old "M-x guix" (interface for guix shell commands) was renamed to
  "M-x guix-command".  Also you can reach it from the new "M-x guix"
  with "c" key.

* M-x guix-set-emacs-environment

  This command sets Emacs environment according to a specified profile.
  Note that after calling this command, the whole Emacs will have a new
  environment (you may check ‘process-environment’ variable), so "M-x
  shell" or any other process will inherit this environment.

  Many thanks to Jan Nieuwenhuizen for inventing and implementing this
  command.

* "Total size" messages in "Guix Store Items" buffer

  Now, whenever this buffer is displayed (for example, after "M-x
  guix-store-dead-items"), a minibuffer message will display total size
  of the listed store items.  Also you can mark several items (with "m")
  and press "z" to get their total size.

  Thanks to Pierre Neidhardt for the idea of this feature.

I love Emacs-Guix - thank you for this.

Relatedly - I'm trying to debug an issue: so on my both pure GuixSD
machine and on my Arch machine with standalone Guix binary installer,
=guix-all-packages= shows me 9213 packages, but on my Void machine with
standalone Guix binary installer, the same command only shows me around
900(!) packages. But on the same machine, the expected full range of
Guix packages are available in the terminal via =guix package=. What
could cause Emacs-Guix to only show a subset of packages in this one
case?

Dear Benjamin,

If I understand well, it is the same issue than the one reported here:
https://github.com/alezost/guix.el/issues/28

Recently, Alex explained why in the second part of this message:
https://lists.gnu.org/archive/html/help-guix/2019-01/msg00020.html

One (not-yet satisfactory) fix seems to install guix itself in the profile:
  guix package -i guix
then to correctly add ~/.config/guix/current/.
It works for me.

Hope that help.


All the best,
simon

zimoun answered correctly.  I think it is the same problem as several
people have on non-GuixSD system.  Most likely, it will not be fixed on
Emacs-Guix side.  The only workaround I know is "guix package -i guix".

Would it be feasible for Emacs-Guix to use
“~/.config/guix/current/bin/guix repl”, which would have the effect of
setting the load path as expected?

Thanks all, doing `guix package -i guix` indeed solved this issue.

This is generally not recommend, because you’ll end up with an older
Guix than the one you installed it with.  To ensure that the correct
Guix is used, please make sure that ~/.config/guix/current/bin appears
first in PATH.

Interesting idea!  But AFAICT it is impossible: Emacs-Guix needs to run
Geiser in one way or another, but if you try:

  (setq geiser-guile-binary '("guix" "repl"))
  "M-x geiser"

it will fail because geiser tries to run it with "-q" and "-L" (with a
directory with Geiser Guile modules).  Obviously these options are not
supported by "guix repl".  Above that, Emacs-Guix uses "--listen"
option.

So I'm afraid as long as "guix repl" options are incompatible with
"guile" ones, it can't be used by Emacs-Guix.

It would make sense to add these options to ‘guix repl’.
