Hi again :)

I was discussing "channels in practice" with Zimoun and we were asking
ourselves: Can we pull a specific channel without pulling
%default-channels?

If not, is there a convenient way to edit+test the package definitions
in local channels?

Maybe I'm missing the obvious?

Hello Pierre,

I’ve been working a lot on some packages in a private channels and my workflow is usually focused on building properly which is a matter of:

guix build -L /path/to/channel <package>

To test runtime behavior I still have to pull which does mean pulling the default channel, too.  This so far has worked well. If pulling becomes too much, maybe specifying a commit of the default guix channel could work. What do you think?

- John

Yes, that would work.  I tried something like the following:

--8<---------------cut here---------------start------------->8---
(list (channel
        (name 'guix-chromium)
        (url "https://gitlab.com/mbakke/guix-chromium.git")
        (branch "master"))
       (channel
        (name 'guix)
        (url "https://git.savannah.gnu.org/git/guix.git")
        (branch "master")
        (commit "1d4c2dabefdc5e957ed74a58066f8faa8e0fb70e")))
--8<---------------cut here---------------end--------------->8---

Is there a way to inherit or modify %default-channels to avoid all the
copy-pasting?

Also do you know how to get the last guix generation commit?

It’s just a list.  You can cons onto it.

What I meant is that it does not seem possible to

--8<---------------cut here---------------start------------->8---
(list (channel
       (inherit %default-channels
			 (commit "..."))))
--8<---------------cut here---------------end--------------->8---

Or even

  (set-channel-commit %default-channels "...")

But maybe it's not worth it considering it's only 4 lines.

FYI, I believe you can also specify local paths in the channel
description file, itself, either by saying "file:///path/to/channel" or
"/path/to/channel" - I can't remember which.

‘%default-channels’ is a list, not a <channel> record, so what you
suggest above cannot work.

But you can do:

  (list (channel
          (inherit (first %default-channels))
          …))

That’s what the stable-channel trick I posted does.

Damn, my bad, I completely missed the obvious here.  Thanks for answering this, Ludo!
