Calcium, Thanks for the report!
In future, please submit separate issues separately, it helps keep discussion, er, separate. It's easier to merge issues than to split them.
Can't (specification->package "package@version:output")
Short answer: it is not intended to work. Use specification->package+output if you want outputs. This is not a bug but a design decision. Which are not above critique, but guix-devel@ might be a better place for that.
I've considered in the past to submit a cheeky patch silently renaming specification->package+ouput to specification->package, just to avoid this FAQ. It should be almost perfectly backwards compatible in that no existing code should break with the same input.
However I think clarity the greater value here, and did not submit such a patch.
calcium via Bug reports for GNU Guix 写道:
The syntaxe to specify a package version and desired output only works on guix install package@version:output guix remove package@version:output doesn't works
I cannot reproduce this: $ guix install git@2.34.0:send-email $ guix remove git@2.34.0:send-email $ Can you provide an example?
guix remove package@version doesn't works
‘package@version’ means ‘package@version:out’, not (a hypothetical) ‘package@version:*’ wildcard. It neither installs nor removes ‘all outputs’.
I did notice that, e.g., $ guix install git@2:send-email $ guix remove git@2:send-emailguix remove: error: package 'git@2:send-email' not found in profile
$is asymmetrical. I wonder if there are any drawbacks to making it work.
Kind regards, T G-R
