Currently you have to start with:

  (use-modules (gnu packages))

This will set up ‘%load-path’ so that channel modules become visible.
Let me know if it works for you!

This is a bug we should fix.

HTH,

btw, "shell" behaves similarly - only sees the "system" channel:

$ guix time-machine --channels=channels.scm -- shell -- guix describe
guix shell: warning: no packages specified; creating an empty
environment

              commit: a0751e3250dfea7e52468c8090e18c3118d93a60

can this also be considered a bug? if so, is it worth sending a separate
bug report?

This command is running ‘guix describe’ with the ‘guix’ command that
happens to be in $PATH; in addition, the ‘shell’ bit does nothing, as
shown by the warning above.

What you probably meant is:

  guix time-machine -C channels.scm -- describe

Ah, I thought it was expected. :-)  Well, my ~/.guile looks like:

--8<---------------cut here---------------start------------->8---
(use-modules
 (ice-9 readline)
 (ice-9 format)
 (ice-9 pretty-print)

 (guix)
 (gnu packages)
 (gnu packages base))
(activate-readline)
--8<---------------cut here---------------end--------------->8---

so it avoids me this kind of annoyance.

Well, do we open another ticket or just retitle this one?


Cheers,
simon
