guix.el's Issues

Need help about C-c . b

When I C-c .b, the problem is showed like below:

scheme@(guile-user)> (begin
      (guix-warning-port (current-warning-port))
      (current-build-output-port (current-error-port)))
$2 = #<output: file 9da3f18>
scheme@(guile-user)> ,run-in-store (build-package emacs-exwm-x #:use-substitutes? #t #:dry-run? #f)

ERROR: Throw to key `srfi-34' with args `(#<condition &message [message: "gcc-arm-bug-71399.patch: patch not found"] 9b3acb0>)'.
scheme@(guile-user)>

Any suggestion? The below is my guix config

(require 'guix)
(require 'geiser-guile)

(global-guix-prettify-mode)

(setq geiser-debug-jump-to-debug-p nil)

(setq guix-directory "~/project/guix")

(with-eval-after-load 'geiser-guile
  (add-to-list 'geiser-guile-load-path "~/.config/guix/latest/")
  ;; (add-to-list 'geiser-guile-load-path "~/project/guix/")
  )

(add-hook 'scheme-mode-hook 'guix-devel-mode)

Add a guix-report-bug command

It would be nice to have a guix-report-bug command that mirrors report-emacs-bug.

guix-system-from-file fails

When I use guix-system-from-file on my system config it fails, I used (setq debug-on-error t) to get the backtrace below:

By looking at it, this could end in a problem with guiser but since it stems from guix I brought the issue here.

Can't run guix commands

I'm running emacs27.1 from guix upstream on ArchLinux.

Right now, I can't run guix commands using the emacs interface. When I try to search for a package(guix package-search. I get: Starting GUIX REPL... then: No prompt found. How do I work around this? I have guix and guile:

➜  ~ guix --version

➜  ~  guile --version
guile (GNU Guile) 3.0.4

Does this package work for people on foreign distros?

failed to load modules.

Running guix-all-packages or guix-number-of-packages (maybe other commands as well) produces the following warning in "Guix REPL", and the displayed total number of packages 1341, which is significantly less than actual number of packages.

Using guix pull complains about lack of bootstrap binaries.

When running guix pull via M-x guix, P, r, I get a *Guix Repl* with the following output:

I am using

GNU Emacs 25.2.1 (x86_64-unknown-linux-gnu, GTK+ Version 3.22.15) of 2017-08-14
guix.el 0.3.3
guile 2.2.2
I am currently running binary guix on Ubuntu 17.04.

Some debugging on the created guix repl gives me the following:

scheme@(emacs-guix)> (guix-command-output "pull")
$4 = ""
$5 = "guix pull: error: could not find bootstrap binary 'guile-2.0.9.tar.xz' for system 'x86_64-linux'\n"

Invoking guix pull from any shell does seem to have the desired effect, and does not mention the bootstrap binary problem.

Error when running in a foreign distro

Hi, I am running Guix in two laptops, one is a full GuixOS and in the second one guix runs in a foreign distro (pop os!).

I don't have any problem running emacs-guix in the GuixOS laptop, but I am getting the following error in the foreign distro:

emacs-guix does not truly install

Using a GUI system, the command guix package -i emacs-guix

installs nothing but a single .el file, and the only command it provides is (guix-emacs-autoload-packages) . The documentation isn't helping me.

C-c C-z (switch-to-geiser) does not work

From a Scheme buffer in Guix mode:

M-x guix-switch-to-repl
; Point is not in the Guix REPL.
M-x switch-to-geiser
; Does nothing.

Is there a way to go back to the calling buffer?

org-mode Scheme source code block collides with guix-devel-code-block-edit

Hello Alex,

Before a new emacs-guix release, I want to discus a org-mode Scheme source code block:

#+BEGIN_SRC scheme

#+END_SRC

C-c ' inside this source code block will invoke a new buffer and window. After finishing typing a code, I assume to close it with C-c ', but instead I get a message user-error: The point should be inside ’description’ or ’synopsis’.

So, guix-devel-code-block-edit collide with a default well known by users org-mode behavior. Could we bind guix-devel-code-block-edit to another key?

Unable to compile locally

Hi, I tried to compile and install locally guix.el to play a bit with the code but I was unable to do it.

Those are the steps I did:

guix environment -l guix.scm
./autogen.sh
./configure --prefix=$PWD/install
make

Make fails when compiling the .el files. The problem seems to be in the build-aux/build-env.el file. This file seems to load the autoload definitions inside the guix enviroment using the function guix-emacs-autoload-packages passing it the environment directory.

The problem I have is that my guix installation defines that function not taking any argument, so that code fails.

I don't really know if I'm missing something or just that little script is broken but I managed to workaround it removing the argument, setting the EMACSLOADPATH env variable to point the environment and adding -q (why do it needs to load my init files?).

Am I missing something on how to build it locally using guix?

Thanks.

About %load-path

My question is: the first two path come from where? they are always in the begin of list

Enter `,help' for help.
scheme@(guile-user)> %load-path
$2 = ("/home/feng/.config/guix/latest" "/home/feng/.emacs.d/elpa/geiser-20170704.1044/scheme/guile/" "~/.config/guix/latest" "/home/feng/.emacs.d/elpa/geiser-20170704.1044/scheme/guile" "/run/current-system/profile/share/guile/site/2.2" "/gnu/store/jkhydh37k4dcrw3mhcv2hlcipalmpblf-guile-2.2.2/share/guile/2.2" "/gnu/store/jkhydh37k4dcrw3mhcv2hlcipalmpblf-guile-2.2.2/share/guile/site/2.2" "/gnu/store/jkhydh37k4dcrw3mhcv2hlcipalmpblf-guile-2.2.2/share/guile/site" "/gnu/store/jkhydh37k4dcrw3mhcv2hlcipalmpblf-guile-2.2.2/share/guile")

This is my config:

  (setq guix-directory "~/project/guix")
  (setq geiser-debug-jump-to-debug-p nil)
  (add-hook 'after-init-hook 'global-guix-prettify-mode)

    (add-to-list 'geiser-guile-load-path
                 (concat (file-name-directory (locate-library "geiser.el"))
                         "scheme/guile"))
    (add-to-list 'geiser-guile-load-path "~/.config/guix/latest")))

guix-devel-mode's function fail on package ending with "+"

On emacs-image+, C-c . b tries to run

,run-in-store (build-package emacs-image #:use-substitutes? #t #:dry-run? #f)

The + is missing. The command works if I add the + manually.

Evil bindings for guix.el released!

Just to let you know: I've just added support for guix.el to Evil Collection.

Comments are welcome!

@alezost: It was a good opportunity to explore the various features of guix.el a bit more in depth: I'm amazed by how rich and polished the user experience is. You've done a fantastic job here!

Move to Gitlab

I see there is a new website and a Gitlab repo:

Planning on moving there permanently?
If so, instead of creating a new repository on GitLab, you should "import" this repository on GitHub so that all issues and pull requests get copied along.

Also don't forget to redirect from the GitHub repo and to update the MELPA recipe :)

"unbound variable" errors

First, thank you for the package! When it's all working it's a joy to use. Unfortunately, right now I am encountering an error.

If I execute M-x guix-package-by-name immediately after starting a fresh Emacs instance, I get the following error (as copied from *Messages*):

guix-geiser-eval: Error in evaluating guile expression: While executing meta-command:
error: %max-returned-list-size: unbound variable

Attempting to run the same command again in the same Emacs instance gives me a slightly different error:

guix-geiser-eval: Error in evaluating guile expression: While executing meta-command:
error: package-names*: unbound variable

This is with emacs 27.2 and emacs-guix 0.5.2-4.8ce6d21 installed via Guix on Guix System. Nothing in my Emacs config should be relevant except the use-package declarations to load the packages:

(use-package geiser-guile)

(use-package guix)

guix-edit does not always honour GUIX_PACKAGE_PATH

It seems that guix-edit and related locations functionality are not able to understand external guix package definitions. Whereas the actual packages names are loaded properly in the selection list after issuing guix-edit (due to that happening in the guix repl, I presume?), the link to e.g. gnu/packages/third-party.scm is resolved to ~/.guix-profile/latest/gnu/packages/third-party.scm, while it is actually in $GUIX_PACKAGE_PATH/gnu/packages/third-party.scm.

Consequently, I cannot currently use guix.el to easily edit my out-of-tree package defintions.

I am using a git checkout of the guix tree in ~/.guix-profile/latest, in case that might influence things.

Doesn't seem to work with Guile 3.0

I end up with a lot of errors of the form:

;;; WARNING: loading compiled file /home/slade/.config/guix/current/lib/guile/3.0/site-ccache/guix/ui.go failed:
;;; In procedure load-thunk-from-memory: incompatible bytecode kind

Broken since the .config/guix/latest -> .config/guix/current change?

I've noticed since the last few weeks that guix.el fails to do many things:

It seems that it sees the package definition from .config/guix/latest (which is now outdated).
All transactions fail (installation, removal).

geiser-company.el has been removed in upstream

The file geiser-company.el had been removed in the geiser upstream repo in Commit 18faa0ba
Consequently, the line

`guix package --list-profiles`?

Dear,

If I read well, the profiles are provided by this piece of code (defcustom) and then listed by this piece of code (defun).

Now there is an CLI to list all the user's profile: guix package --list-profiles.

I am not sure to have my mind clear enough: using this new Guix plumbing, is it better to update the variable guix-profile or the function?

Thank you in advance.
All the best

GuixSD installer for Emacs nerds

Just in idea stage

https://github.com/wigust/guix.el/tree/guixsd-installer

Breaks tab completion in shell-mode buffers

When I type a command other than guix in my shell, I can complete fine. If I type:

l0p!ieure:~$ ls ~/Pro

...and then press TAB, it expands to:

l0p!ieure~$ ls ~/Projects/

If I do the same thing, but with any command beginning with guix, such as:

l0p!ieure~$ guix home reconfigure ~/Pro

...then tab completion doesn't work, and I get this error in my *Messages* buffer:

This happens for any command which begins with guix; if guix is in any position other than the start of the command, it works fine, so commands like ls guix are unaffected.

The immediate issue is that guix-help-string is called with a nil argument, which it can't handle and has no guard for. The potential larger issue is that this is being called when the thing needs to be completed isn't a guix command, but a file path.

Changing guix-help-string to return an empty string when commands is nil prevents the error, but completion of guix subcommands doesn't work, and I'm not convinced this is a proper fix.

I'm using guix.el on GuixSD, installed via Guix. My emacs-guix package version is 0.5.2-7.455272c. Here's the output of guix describe:

latex-mode takes a precedence on .drv files in auto-mode-alist

Hello,

Our derivation mode has a conflict probably with auctex in auto-mode-alist. The latex-mode from auctex takes a precedence. Is it our or auctex problem?

Invoking guix-packages by name in empty line fails

when the point is on an empty line, this fails:

Line 1516 in 8ce6d21

`find-newest-available-packages` disappeared

Hello,

I removed find-newest-available-packages from (gnu packages) in Guix commit e2a903c807ccacec5925f197ce26f626060e1953 (Jan. 2019) because it was not used internally. Only recently did I realize that Emacs-Guix uses it.

Would it be an option for you to re-introduce it in packages.scm in Emacs-Guix proper? WDYT?

Apologies for the breakage!

Guix support in Helm System Packages?

I'm the current maintainer of Helm System Packages, a Helm-powered package manager which supports pacman, portage, dpkg (all Debian-based distributions) and xbps (Void Linux). It also runs over the network via TRAMP!

I was thinking of adding support for Guix but since there is an obvious overlap with guix.el I thought it would be worth discussing the features first.

guix-all-available-packages already provides most of the features of Helm System Packages. Combine it with helm-occur and you get a similar browsing experience.
The main missing feature provided by Helm System Packages is the ability to mark the results of a search.

Thus I would suggest the following: helm-system-packages for Guix would simply switch to the *Guix Packages:... buffer and run a Helm-occur-like session where the action is to mark the packages. The downside is that it would not work over the network.

Otherwise I could just go ahead and re-implement an independent cache of the list of packages.

Thoughts?

ws-butler and selectrum break package search

Steps

Turn on ws-butler-global-mode and selectrum-mode.
Call guix-package-by-name and select any package.

Here, I select the "go" package. Result:

if: Error in evaluating guile expression: ice-9/boot-9.scm:1685:16: In procedure raise-exception:
In procedure string-index-right: Wrong type argument in position 1 (expecting string): #("go" 0 2 (ws-butler-chg chg))
   
Entering a new prompt.  Type `,bt' for a backtrace or `,q' to continue.
scheme@(emacs-guix) [1]>

I'm not sure what's happening but at a guess, ws-butler is active in the selectrum minibuffer and propertizes the string candidate we send to Guile.

This is a workaround that perhaps should be upstreamed to ws-butler:

(add-to-list 'ws-butler-global-exempt-modes #'minibuffer-inactive-mode)

If I'm right that it's text properties, perhaps guix.el could de-propertize any strings before sending them to external programs.

Shows packages from previous pull on foreign distro

As I mentioned in this thread on help-guix, using the recommended workaround for foreign distros as indicated in #28 and #29 didn't really work for me. At first it seems that package lists work, however on close inspection I noticed that emacs-guix shows package descriptions from the previous pull.

For example, after pulling with guix pull and updating packages with guix package -u, running guix package -s guix yields version 1.0.1-15.0984481 (which matches ~/.guix-profile/bin/guix --version and the description shown by guix edit guix). However, if I then run a new Emacs and open guix-installed-packages, guix is marked as being "from the future":

guix 1.0.1-15.0984481

This package is from the future, i.e. this (installed) package
is newer than the available package recipe for guix.

And when I follow the "guix" link to open that recipe, it is for guix 1.0.1-14.c2f9ea2 (i.e. that in the previous pull). In fact, opening guix in guix-all-packages shows the description of guix 1.0.1-14.c2f9ea2 straight away.

I don't know if this is something that would go away by using guix repl internally, but I'm happy to do whatever testing is needed.

Thanks a lot for the very nice package!

wrong search with regexp

Dear,

Giving a look to the guix search command, see [1] and [2], I notice that M-x guix p r drawing tools outputs only these 2 packages texlive-latex-eepic and tuxpaint.

The good news is that the issue reported in guix search is not in M-x guix p r. :-)
The bad news is that---for example---the package r-cli is not listed and it should be because the description field has the both terms drawing and tools.

Do I miss something?

Thank you in advance.
And thank you for this nice interface.

All he best,
simon

Managing Guix on a remote machine via TRAMP

Is it possible to use guix.el to manage a remote machine via TRAMP? Is it as simple as changing all of the variables like guix-state-directory, or would that not work?

Deleting system generations

At the moment it seems that it's not possible to delete system generations without starting Emacs as root.

Would it be possible to lift this limitation for example using TRAMP?

Besides, is it possible to delete a system generation from the commandline?

Issues with "size" command

When the package is not installed guix.el should warn the user appropriately. Instead it returns:

no result in text mode,
"no file ... found" in image mode.

When the package is installed, image mode fails with:

guix-geiser-eval: Error in evaluating guile expression: guix/scripts/size.scm:202:4: In procedure profile->page-map:

guix-geiser-eval - Unknown meta command: geiser-eval

Hello,

Issue

I use guix package manager on a Fedora 33. Emacs is installed from the fedora repo and guix.el from elpa/melpa.

Whenever I run a command that interact with geiser, I face the following error:

guix-geiser-eval: Error in evaluating guile expression: Unknown meta command: geiser-eval
$7 = #f
$8 = "GNU Guix"
While compiling expression:
ERROR: Syntax error:

scheme@(emacs-guix) [6]>

The text following the first line changes following which action I want to perform.

I can launch the geiser REPL with run-geiser, without problems.

M-x guix doesn't seem to be working for me with the above minimal config using guix-installed versions of these packages. I'd appreciate any help. I'm using Geiser v 0.10 and Guile 2.2.4. Thanks for your time.

"Guix REPL ... No prompt found!" ( -> Emacs package unusable ? )

Package seems to get installed by

, yet when one goes M-x 'guix-installed-packages..." i get

(let me add that a Guile REPL prompt is opened in another parallel buffer, though )

... thus, leaving the package unusable.

Thanks, thanks, thanks

I discovered if I remove rm .emacs.d/elpa/async-20200809.501/ -rf (a dependency of magit), guix-popup works well again.

Some infomations:

guix install -i emacs emacs-guix, still unable to run M-x guix commands

I've installed emacs and emacs-guix yet nothing happens when I type M-x guix inside emacs. Am I missing something obvious? Let me know what additional information I can provide, as I'm an emacs noob.

$ guix package -I | grep emacs
emacs	27.1	out	/gnu/store/7mvfn7d96q61lmya9j6hw77zn0z45d2q-emacs-27.1
emacs-guix	0.5.2-3.a694fdb	out	/gnu/store/p7n9i8gjz29w68dmywz8n50fdmwpb47n-emacs-guix-0.5.2-3.a694fdb

a checked out guix

Say I have a foder with a checked ot guix master branch in it

Manually, I use to cd into that folder, then call

.pre-ins-env guix ... blah blah
.pre-ins-env guile ... blah blah

I'd like the manual to give an example of how to configure the guix-guile-program variable in order to have Emacs-Guix using the guix/guile from within that folder as I do manually

Thanks

Installing guix doesn't install it's dependency geiser-guile

It looks like this package doesn't specify geiser-guile as it's dependency. Whenever I try to execute the command guix-packages-by-name, Emacs says eval-buffer: Cannot open load file: No such file or directory, geiser-guile. I've solved the problem by installing geiser-guile myself, but it should be automatically install when someone installs guix.

    guix install emacs
	guix install emacs-guix
	emacs -nw -q
	M-x guix-all

I get

What am I doing wrong ? Thanks !

guix-devel: generate a shell command string which used to build current "define-public"

I want to a command, which can generate a command string, for example: "guix build -f /temp/path/emacs-exwm-x.scm emacs-exwm-x", so I can use this command to build package current be edited
