New commands

• M-x guix-lint-checkers
  It shows a new "list" interface for package linters.

• M-x guix-hidden-packages
  It shows packages that are hidden from users.

Removed command

• M-x guix-newest-packages
M-x guix-all-packages should be used instead.

Changed command

• M-x guix-package-lint
  It asks for multiple packages now.

Changes in Profile List

Now it displays all profiles that have gc roots (similarly to
guix package --list-profiles shell command).

This is a bug-fix release: M-x guix, introduced by the previous release, failed after pressing p or P because of a missing requirement in guix-popup.el. This is fixed in this release (commit d7b5478).

Announcement

New popup interface for Emacs-Guix commands — M-x guix

The old M-x guix (interface for guix shell commands) was renamed to
M-x guix-command (also it is one of the sub-popups of the new M-x guix now).

New key binding in *Guix Store Items* buffer

z: display a total size of the marked store items.

New M-x commands

• guix-set-emacs-environment
• guix-current-profile

New variables

• guix-file-size-string-function
• guix-store-item-show-total-size

Announcement

Interface for store items (added)

New commands analogous to guix gc shell command:

• guix-store-live-items
• guix-store-dead-items
• guix-store-item
• guix-store-item-referrers
• guix-store-item-references
• guix-store-item-requisites
• guix-store-item-derivers
• guix-store-failures

Interface for Hydra (removed)

It was moved to emacs-build-farm package which was announced here.

This is a bug-fix release: earlier version of guix pull command put
.go files into the same directory as .scm, but now they are placed
in different directories. This change is supported by this release. It
is a crucial change, as incompatibility between .scm and .go files
may lead to unpredictable errors.

Announcement

New commands

• M-x guix-system-from-file

  This is the new interface for operating-system declaration from your
  GuixSD configuration .scm file.

• M-x guix-system-profile

Support for the latest changes in guix pull

• Now guix pull makes a new full-featured profile (~/.config/guix/current) instead of just building the latest guix modules and putting them into ~/.config/guix/latest directory. This change is supported by this Emacs-Guix release.

• Also the "pulled" profile is displayed by M-x guix-profiles.

• The famous symlink hack (pointing ~/.config/guix/latest to your guix git checkout) does not work anymore, so if you relied on it to make Emacs-Guix use guix modules from your git checkout, now you need to set guix-load-path variable.

Announcement

Interface for services and their locations

It is very similar to the interface for packages. The new commands are:

• M-x guix-all-services
• M-x guix-default-services
• M-x guix-services-by-name
• M-x guix-services-by-regexp
• M-x guix-services-by-location
• M-x guix-service-locations
• M-x guix-find-service-definition
• M-x guix-find-service-location-file

Other new commands

• M-x guix-find-license-location-file
• M-x guix-dependent-packages
• M-x guix-number-of-packages
• M-x guix-report-bug

Renamed commands

• M-x guix-all-available-packages -> guix-all-packages

• M-x guix-newest-available-packages -> guix-newest-packages

• M-x guix-find-location -> guix-find-package-location-file

• M-x guix-locations -> guix-package-locations

• M-x guix-edit -> guix-find-package-definition

  guix-edit still exists as an alias for guix-find-package-definition and it is not going to be removed.

Additions for guix-devel-mode

• Possibility to edit synopsis/description in texinfo-mode

  When in .scm buffer with Guix packages, press C-c . ' to edit synopsis or description of the current package in texinfo-mode.

• Possibility to find package patch file at point

  To activate it, use:

  (add-to-list 'ffap-alist '("\\.patch" . guix-devel-ffap-patch))

guix-env-var-mode

It prettifies /tmp/guix-build-*-*.drv-*/environment-variables and
etc/profile files (enabled automatically).

Performance improvements

Big portions of Guile data are passed to the Elisp side not through Geiser, but through a temporary file. This makes Emacs-Guix faster and more reliable. See commit 00c87a9 for details.

New commands

• M-x guix-hash

• M-x guix-superseded-packages

• M-x guix-derivation-mode

  It is enabled automatically in /gnu/store/….drv files.

Along with "obsolete" packages, names of "superseded", "unknown" and
"future" packages are also highlighted.
