[ANN] Emacs-Guix 0.4.1

[ANN] Emacs-Guix 0.4.1

[Alex Kost]

Hello, Emacs-Guix (Emacs interface for GNU Guix) version 0.4.1 has been
released.  If you are not familiar with it, you may start with:
‘guix package -i emacs-guix’ and "M-x guix-about".

The main purpose of this release is to support the recent changes in
"guix pull" (i.e., using "~/.config/guix/current" instead of
"~/.config/guix/latest").

However, there is one new feature:

- M-x guix-system-from-file

  This command allows you to look at 'operating-system' declaration from
  a .scm file (the one that you use for "guix system …" commands).  It
  doesn't show much, but maybe you'll find something interesting there.

- Also "M-x guix-profiles" displays "~/.config/guix/current" profile now
  (if you have it), so you can look at its generations (with "G" key),
  roll back, etc.

Hi Alex!

Thanks a lot for this release!

I'm still having issues however:

1. `guix-installed-user-packages' does not seem to know about the
updated guix packages after a `guix pull'.

2. All transactions fail, for instance:

--8<---------------cut here---------------start------------->8---

I don't know.  This error looks like guile load paths are not set
correctly.  Could you switch to Guix REPL and check whether %load-path
contains "~/.config/guix/current/share/guile/site/2.2" ?

...Oh, wait, I've just noticed that the mentioned directory contains
only .scm files.  When I experimented with "guix pull", it contained
both .scm and .go files, but now .go files are installed in
"~/.config/guix/current/lib/guile/2.2/site-ccache".  Apparently there
was another more recent change in "guix pull", that I did not notice.

This incompatibility between .scm and .go files may lead to
unpredictable problems, so I think I have to make another release :-)
Thanks for reporting!

To make sure that this is indeed the problem you have, could you please
add the following to you emacs config:

(setq guix-load-path "~/.config/guix/current/share/guile/site/2.2"
      guix-load-compiled-path "~/.config/guix/current/lib/guile/2.2/site-ccache")

and check if this fixes the problem you mentioned or not.

Indeed, I had this:

	(add-to-list 'geiser-guile-load-path "~/projects/guix")

as per "(guix) The Perfect Setup" of the Guix manual.  Removing this
fixed the transaction issues.

Insights?

But the wrong outdated packaged remained.

This fixes the oudated package issue.

"~/.config/guix/current/…" overrides "~/projects/guix" in %load-path of
Guix REPL, but the problem is that %load-compiled-path does not have the
according .go files as I wrote in the previous message, so the
incompatibility between .scm (from "~/.config/guix/current") and .go
(from "~/projects/guix") led to errors.

I have fixed it in Emacs-Guix:

  https://notabug.org/alezost/emacs-guix/commit/38a20cefe14969970817de97693c3f0f00b1c099

BTW if you want Emacs-Guix to use Guix modules from your checkout, you
can set it like this:

  (setq guix-load-path "~/projects/guix")

This ↑ setting overrides everything (including the profile populated by
"guix pull").

Great, thank you for checking!  I have made a new release (0.4.1.1), so
hopefully it should be OK now :-)

Hmm... I think there is a misunderstanding.
With 

	(add-to-list 'geiser-guile-load-path "~/projects/guix")

I still experience the transaction issue.
Can you reproduce?

No.  Please show what "M-: (guix-repl-guile-args)" returns.

This geiser-guile-load-path should be placed after
"~/.config/guix/current/…" in guile %load-path so it shouldn't make any
effect.  So the only possibility for your error I see is that the
"pull"-ed directories are not added to the guile load paths.

Also, please check the values of %load-path and %load-compiled-path
variables in Guix REPL.

Aha! here it is: your "~/projects/guix" appears before the pulled
profile.  I think it can happen only if you added it to
GUIX_PACKAGE_PATH, did you?

I think GUIX_PACKAGE_PATH is intended only for the user packages, not
for the whole guix checkout as it may lead to problems (I forgot what
kind of problems but I recall people did this in the past and had some
troubles).

Anyway, it should probably work… but only if your checkout is built
properly.  Did you run make there? any errors?  maybe there are some ABI
incompatibilities ("make clean-go" and "make" should fix them).  Did you
experience any problem with "guix" shell commands?

No I did not:

So the issue is something else.  Any idea?

As I told I think this issue happens because your "~/projects/guix"
appears too early in %load-path.  But I thought it could happen only if
you added it to GUIX_PACKAGE_PATH, but since you didn't, I have no idea,
sorry.
