summary: ------- This commit adds xdg-desktop-portal support to waybar. If a portal supporting `org.freedesktop.portal.Settings` exists, then it will be queried for the current colorscheme. This colorscheme will then be used to prefer a `style-light.css` or `style-dark.css` over the basic `style.css`. technical details: ----------------- Appearance is provided by several libraries, such as libhandy (mobile) and libadwaita. However, waybar links to neither of these libraries. As the amount of code required to communicate with xdg-desktop portal as a client is rather minimal, I believe doing so is better than linking to an additional library. The Gio library for communicating with dbus is rather messy, Instead of the `Portal` class containing a `Gio::Dbus::Proxy`, it extends it which simplifies signal handling. `Portal` then exposes its own signal, which can be listened to by waybar to update CSS. For a reference implementation, please see another one of my projects: https://github.com/4e554c4c/darkman.nvim/blob/main/portal.go test plan: --------- If no desktop portal which provides `Settings` exists, then waybar continues with the log line ``` [2023-09-06 14:14:37.754] [info] Unable to receive desktop appearance: GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: No such interface “org.freedesktop.portal.Settings” on object at path /org/freedesktop/portal/desktop ``` Furthermore, if `style-light.css` or `style-dark.css` do not exist, then `style.css` will still be searched for. Waybar has been tested with both light and dark startup. E.g. if the appearance is dark on startup the log lines ``` [2023-09-06 14:27:45.379] [info] Discovered appearance 'dark' [2023-09-06 14:27:45.379] [debug] Try expanding: $XDG_CONFIG_HOME/waybar/style-dark.css [2023-09-06 14:27:45.379] [debug] Found config file: $XDG_CONFIG_HOME/waybar/style-dark.css [2023-09-06 14:27:45.379] [info] Using CSS file /home/pounce/.config/waybar/style-dark.css ``` will be observed. If the color then changes to light during the operation of waybar, it will change css files: ``` [2023-09-06 14:28:17.173] [info] Received new appearance 'dark' [2023-09-06 14:28:17.173] [debug] Try expanding: $XDG_CONFIG_HOME/waybar/style-light.css [2023-09-06 14:28:17.173] [debug] Found config file: $XDG_CONFIG_HOME/waybar/style-light.css [2023-09-06 14:28:17.173] [info] Using CSS file /home/pounce/.config/waybar/style-light.css ``` Finally, tested resetting waybar and toggling style (works, and style is only changed once). fixes: Alexays/Waybar#1973 |
