CLI flag to ignore guix channel

CLI flag to ignore guix channel

[jgart]

Hi,

I'd like a CLI flag to be able to ignore channels.

Where should I look if I'd like to implement something like this?

I prefer not to edit and comment out channels in ~/.config/guix/channels.scm

I'd prefer to do the following

guix import crate behemoth-rust-package-foo -r --ignore-channel=guixrus

WDYT

Well, this would be nice but we have nothing in this direction.

From my point of view, the best is to have several channels.scm files
where some or other channels are defined.  Then, you switch using “guix
time-machine”, for example:

    guix time-machine -C path/to/channels-wo-guixrus.scm \
         -- import crate behemoth-rust-package-foo -r

HTH,

How fast is that?  If new commits come in during time-machine
invocations, won't it keep doing new builds of guix?

It depends what the file ’path/to/channels-wo-guixrus.scm’ would contain. :-)

My point was just to say that this speculative “ignore-channels” could
already be emulated using “guix time-machine”.  From my understanding of
what this speculative “ignore-channels” would do.

BTW, please note that this operation “ignore-channel” would be costly
because at least one “Computing Guix derivation” is required.
