I agree that’s more flexible but that’s also less nice as a UI.
And it’s not as simple as this. Currently one can do:
guix build emacs guile \
--with-source=emacs-2123123.tar.gz --with-source=guile-12321.tar.gz
and it does the right thing.
Here we wouldn’t know what package --override-name and
--override-version apply to.
For non-trivial use cases, I would suggest writing a file like this:
(use-modules (guix) (gnu packages emacs))
(package
(inherit emacs)
(name "emacs-snapshot")
(source "/path/to/some-file-or-directory.tar.gz"))
and then run:
guix package --install-from-file=that-file.scm
WDYT?
