font-packaging guidelines

[not emma]

Hi !

I hope this is the right place to send this. First off, I've only been using Guix for a month now but wow I love it!  After getting the hangs of the basics I managed to create a working package for the JetBrainsMono Nerd Font  that's based off the code from this patch:

https://issues.guix.gnu.org/44476

However, rather than lumping all the fonts into a single package, I'm planning to package each one independently, and have them exist as part of a nerd-fonts module. I'd like to submit this package as a contribution so that others can use it too, but wanted some clarification on packaging guidelines before i started to write out the bulk of the code.

Currently, it's formatted like so:

   1   │ (define-module (bugchan packages font-nerd-fonts)

   2   │   #:use-module (guix packages)

   3   │   #:use-module (guix download)

   4   │   #:use-module (guix build-system font)

   5   │   #:use-module ((guix licenses) #:prefix license:))

   6   │

   7    │ (define-public font-jetbrainsmono-nerd-font

   8    │ (let ((version "v3.2.1"))

   9    │   (package

  10   │    (name "font-jetbrainsmono-nerd-font")

  11   │    (version version)

  12   │    (source (origin

  13   │         (method url-fetch)

  14   │         (uri (string-append "https://github.com/ryanoasis/nerd-fonts/releases/down

          │ load/" version "/JetBrainsMono.tar.xz"))

  15   │         (sha256

  16   │          (base32

  17   │                "01j0rkgrix7mdp9fx0y8zzk1kh40yfcp932p0r5y666aq4mq5y3c"))))

  18   │    (build-system font-build-system)

  19   │    (arguments

  20   │     `(#:phases

  21   │       (modify-phases %standard-phases

  22   │              (add-before 'install 'make-files-writable

  23   │                  (lambda _

  24   │                    (for-each

  25   │                     make-file-writable

  26   │                     (find-files "." ".*\\.(oft|otc|ttf|ttc) $"))

  27   │                    #t)))))

  28   │    (home-page "https://www.nerdfonts.com/")

  29   │    (synopsis "Iconic font aggregator, collection, and patcher")

  30   │    (description

  31   │     "Nerd Fonts patches developer targeted fonts with a high number

  32   │ of glyphs (icons). Specifically to add a high number of extra glyphs

  33   │ from popular ‘iconic fonts’ such as Font Awesome, Devicons, Octicons,

 and others.")

         (license license:expat))))

I followed the packaging guidelines from the manual, but wanted to double check still just in case I missed anything.

Thank you!
