Snap support

[tvsfx]

Would you be open to supporting a snap package of this theme? I wanted to use this theme in my firefox/thunderbird snaps, so I went ahead and hacked together a quick snap that does the job on my end. I solely use rose-pine-moon, so that's what I packaged for now.

I followed the structure of the gtk-common-themes snap.

Manifest for rose pine moon snap

name: rose-pine-moon
version: '1.0'
summary: Rose pine moon but snapified
description: Took inspiration from the gtk-common-themese template and used this to snapify rose-pine-moon

# We build against Ubuntu 24.04 packages, but use the "bare" base as
# we don't want to force installation of a large base snap.
build-base: core24
base: bare
compression: lzo

grade: stable
confinement: strict

slots:
  gtk-3-themes:
    interface: content
    source:
      read:
        - $SNAP/share/themes/rose-pine-moon
  icon-themes:
    interface: content
    source:
      read:
        - $SNAP/share/icons/rose-pine-moon


parts:
  themes:
    plugin: dump
    source: ./themes/rose-pine-moon/
    organize:
      '*': share/themes/rose-pine-moon/
  icons:
    plugin: dump
    source: ./icons/rose-pine-moon/
    organize:
      '*': share/icons/rose-pine-moon/

Then with the following file structure (the rose-pine-moon folder is just taken from this repo, with the caveat that if you take the icons release there's some unresolved symbolic links that snapcraft gets mad over, so I had to copy the folder from sources directly ):

├── icons
│   └── rose-pine-moon
├── snapcraft.yaml
└── themes
    └── rose-pine-moon

You just build the snap and then run

for i in $(snap connections | grep gtk-common-themes:gtk-3-themes | awk '{print $2}'); do sudo snap connect $i rose-pine-moon:gtk-3-themes; done
for i in $(snap connections | grep gtk-common-themes:icon-themes | awk '{print $2}'); do sudo snap connect $i rose-pine-moon:icon-themes; done

Now running GTK_THEME=rose-pine-moon firefox does the job.
