This reverts commit d7545a6b538813e88195d084f75a3e87065c999e.
The commit led to a test failure in 'tests/guix-package-net.sh'. It
also led to disagreements discussed here:
https://lists.gnu.org/archive/html/guix-devel/2020-02/msg00353.html
Reverting until these are addressed.
* guix/ui.scm (display-generation): Display generation path on new line.
* guix/scripts/describe.scm (channel-commit-hyperlink): Add TRANSFORMER argument.
(display-profile-content): Use TRANSFORMER argument to display URL explicitly
when terminal does not support hyperlinks.
Until now, 'guix describe' would perform ~3K stat calls and ~1K openat
calls because it was pulling (guix scripts pull), which in turn pulls in
many (gnu packages …) modules.
* guix/scripts/pull.scm (display-profile-content, %vcs-web-views)
(channel-commit-hyperlink): Move to...
* guix/scripts/describe.scm: ... here. Remove import of (guix scripts
pull).
* guix/channels.scm (profile-channels): New procedure.
* guix/scripts/describe.scm (display-profile-info)[channels]: Define in
terms of 'profile-channels'.
Fixes <https://bugs.gnu.org/34884>.
Reported by Pierre Neidhardt <mail@ambrevar.xyz>.
* guix/scripts/describe.scm (display-package-search-path): Add catch-all
case for FMT.
Fixes a regression introduced in
795d430d90e41eb172315bfccf79c9f13fc0ebfa whereby 'guix describe' would
no longer display the generation number of ~/.config/guix/current.
* guix/scripts/describe.scm (guix-describe): Call 'canonicalize-profile'.
Previously a command like:
$(readlink -f ~/.config/guix/current)/bin/guix describe
would succeed without printing anything.
* guix/scripts/describe.scm (display-profile-info): Don't call
'generation-file-name' when NUMBER is zero.
* guix/scripts/pull.scm (display-profile-content): Likewise.
