UI whishlist: guix pull channel name?

[zimoun <zimon.toutoune@gmail.com>]

Dear,

Maybe it is already possible and I miss the feature.

Currently, I have a couple of channels described in
'~/.config/guix/channels.scm'. So, "guix pull" fetch all of them in
row. Nice!

Time to time, I would like to only pull one specific channel, e.g.,
only '%default-channels'.

I added the file '~/.config/guix/default-channels.scm' containing only
'%default-channels' and then I run "guix pull -C
~/.config/guix/default-channels.scm'". It is cumbersome.

It seems even trickier to only pull one specific channel because of
the configuration files.


An UI such that "guix pull --channel-names=<name>" where <name> is the
name give in the channel file. Without a short option because this
kind of situation is infrequent.

And with the convention "guix pull --channel-names=none" should pull
only '%default-channels'.

Moreover, time to to time, the channel is broken and I have no time to
fix it but I need to pull for other reasons.


What do you think?

All the best,
simon
