the dark theme of yaru is already used by several apps by default like eye of gnome, totem or can be selected within the app like in gnome todo, gnome builder or in rhythmbox (via the csd plugin):
Yaru-dark as a stand-alone theme which could be selected manually in gnome-tweaks much like adwaita dark, is generally demanded here in the big thread and recently also on github https://github.com/ubuntu/yaru/issues/7321
If you are in a developer environment and manually build the theme with meson, you can simply make all yaru dark by setting
in gtk.scss https://github.com/ubuntu/yaru/blob/master/gtk/src/gtk-3.0/gtk.scss#L7
But to produce/build two versions (yaru and yaru-dark) out of the scss files someone with better meson skills than me/carlo would somehow need to make meson build 1) yaru like always and then 2) build yaru-dark with variant: dark
That is the information from my side, here are questions from @didrocks which I try to answer right here :
what is the state of gtk applications with dark theme (2 and 3) compared to the light variant?
The dark variant for GTK3 is 100% ready and as complete as the light variant, the GTK2 version is non-existant but most people agreed over on github that this would be tolerable
how do you turn the dark variant on?
Currently either by the above mentioned method if one is using meson to build it manually or by setting
gtk-application-prefer-dark-theme=1 in ~/.config/gtk-3.0/settings.ini
what is the plan for documentation?
I am not sure what to answer, since the dark.css is build by selecting all the colors in _colors.scss which have a dedicated dark color for example
$light: if($variant=='light', true, false);
$base_color: if($variant == 'light', #FFFFFF, $inkstone);
$bg_color: if($variant == 'light', #F5F6F7, darken($inkstone, 3%));
$fg_color: if($variant == 'light', $inkstone, $porcelain);
$text_color: if($variant == 'light', #2D2D2D, $porcelain);
I know that GTK wanted to remove the dark variant support (I have already mentioned it), did anyone working on that variant have reached out upstream?
I don’t think anyone of us talked with upstream about the dark version.
What I know is, that some applications in gnome now use the dark theme automatically when the nightmode is applied. (but I don’t know if this already happening in 3.30 or if it was just a preview I saw)
Edit: gnome builder 3.28 is already using this feature
So, it would be great if we can make this happen in the next 2? or 3? days before UI freeze.
