[bug#44518] gnu: Add matterhorn.

Hey Guix,

This packages up a nice CLI client for Mattermost chat servers (a self-hosted,
libre Slack alternative).

Anyway, it's a Haskell package and ended up requiring quite a few
dependendencies along with a few version-updated alternatives to existing
packages.

The attached patch bundles all these up together, but what is the appropriate
convention in this case?

The bulk of the work is completely thanks to the hackage importer, but I did
spend quite a bit of time cleaning these up and sanity checking things.
Everything should pass the lint checks as well as indentation.

Also, for two packages, I had to disable tests. There are comments explaining
why in each case.

Let me know what you think!

[bug#44518] gnu: Add matterhorn.

[( via Guix-patches via]

Hi,

This patch must have slipped through the cracks, but it was mentioned
on IRC today, so I decided to do a little review :)

First of all,

(1) You should have one commit per package.
(2) It's better, though not required, to use the procedure described here[1]
    to send patches, instead of using attachments. This makes it much easier
    to annotate the patch with review comments, at least here in aerc :)

[1] https://paste.sr.ht/~unmatched-paren/9114b1fa3d2088c7c71307dcae0d9e2b3620eb0c

> +    (inputs
> +     `(("ghc-random" ,ghc-random)
> +       ("ghc-quickcheck" ,ghc-quickcheck)
> +       ("ghc-semigroupoids" ,ghc-semigroupoids)))

You should use the "new style" of inputs:

> +    (inputs
> +     (list ghc-random
> +           ghc-quickcheck
> +           ghc-semigroupoids))

Same for any native- and propagated- inputs.

> +    (arguments
> +     `(#:cabal-revision
> +       ("3" "1ndz5x6njl35h73il5c6qpaqd4ynvg21n6k7sb8aq09gfbg544d8")))

There's also a new arguments style:

> +    (arguments
> +     (list #:cabal-revision
> +           (list "3" "1ndz5x6njl35h73il5c6qpaqd4ynvg21n6k7sb8aq09gfbg544d8")))

This is a wee bit too long IMO.

Myself, I consider the length to be about perfect -- it isn't verbosely 
worded, it is only a single paragraph and it clearly explains what it 
can do.

Greetings,
Maxime.

Do you receive email notifications from here, elaexuotee, and are you by any chance still an active Guix user? Matterhorn would be a great addition to Guix packages.
