The syntaxe to specify a package version and desired output
only works on guix install package <at> version:output

guix remove package <at> version:output doesn't works
guix remove package <at> version doesn't works

(specification->package "package <at> version") works
(specification->package "package:output") works

but both (specification->package "packge <at> version:output") doesn't work.
/etc/config.scm:line:col: Throw to key `quit' with args `(1)'.

Even though
guix package --export-manifest
;; => (specifications->manifest (list "package <at> version:output" "package <at> version"))

I tested "package <at> version:output" using "openjdk <at> 11:doc"

[Message part 1 (text/plain, inline)]

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 <at> 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.

I cannot reproduce this:

 $ guix install git <at> 2.34.0:send-email
 $ guix remove git <at> 2.34.0:send-email
 $

Can you provide an example?

> guix remove package <at> version doesn't works

‘package <at> version’ means ‘package <at> version:out’, not (a 
hypothetical) ‘package <at> version:*’ wildcard.  It neither installs 
nor removes ‘all outputs’.

I did notice that, e.g.,

 $ guix install git <at> 2:send-email
 $ guix remove git <at> 2:send-email
 guix remove: error: package 'git <at> 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
