⚠️ Shell Engine Roadmap (see for list of bugs)

Feature description

The list below shows features that needs to be implemented to make Shell Engine fully "feature-complete". Items in "Issues" list should be all checked out before 0.8.0 release.

Roadmap:

Add explanations for custom Shell colors
Implement panel theming
Theme export option (allow user to choose Shell version for which to generate the theme)
Automatic theme variant detection (implement after preset format redesign)
Revert to previous theme option (requires backup functionality implemented)
System-wide theming (required to theme lock screen and GDM)
Theme other colorable Shell assets

Issues:

Fix Quick Settings menu not being themed in GNOME 44
Fix date text color in Today's calendar widget using the same variable as foreground color for accent-colored elements
Fix icons in Quick Settings items not using foreground color for accent-colored elements
Adapt on-board keyboard to support custom themes

Additional Context

There is a Nightly Flatpak Repo available here for trying and reporting bugs of the upcoming Gradience version

Did you read the Code of Conduct?

I have read the Code of Conduct.

Thank you very much for the awesome work. I'm already using the shell engine and it looks really great. I really only noticed one minor thing: the dropdown in the quick settings have default color.

Thank you for your kind words! The issue you described here is the first item in issues list, I'll try to fix it as soon as I have some free time this week.

Perfect. Appreciate it a lot. Sorry for my redundant comment.

Shell doesn't support @var_name so a function for converting each @var_name to the hex/rgb value is needed since @ vars are LibAdwaita only

Fixed in 1a5b1f4. We already have a function to handle that, it was just buggy.

Oh, my bad. I didn't know that Gnome 45 is not supported.
It would be nice to get this message in the UI as well.

Hm, it should be, try this build: https://github.com/GradienceTeam/Gradience/actions/runs/7214048889/artifacts/1115721706

It worked with this build. Thanks!

You're welcome ^^

Using this build, when clicking the apply button next to "Shell Theming Options", nothing happens. The console prints out the following when running flatpak run com.github.GradienceTeam.Gradience.Devel

Is there anyway to fix this?

@CaragC

@CaragC do you have User Themes extension installed? it is needed for the shell theming to work

Yes it is installed and does not show any Gradience themes. The second theme I installed myself.

Hm, that's weird, can you try the latest build? https://nightly.link/GradienceTeam/Gradience/workflows/build/main

This still gives the same error as before, also the same error is given when clicking "Reset Theme"

Do you have the xdg-desktop-portal and libportal packages installed?

Both of the packages are installed

Another issue with Geary after fixing the earlier issue by adding the Adw 1.4 colors to the theme json,

this happens when window is not in foreground,
I can't figure out which backdrop or otherwise color maps to this #303030 color.

EDIT: Earlier this color was #FFF but after a log out and login after applying the theme it turned #303030.

@daudix

Any idea about the above issue @daudix ?

I've no idea, the version from main has some issues with sidebar theming, you can try beta1 which appears to not have these

Gnome 46 support hasn't been added, adding this so others can find it: #871
