Add opt-in bar-css-states option to wlr/taskbar module.
When enabled, the module tracks the active workspace and updates CSS
classes on window#waybar to reflect the current window state:
- toplevel-active: when a window is focused
- toplevel-maximized: when any non-minimized window on active workspace is maximized
- toplevel-minimized: when the active window is minimized
- toplevel-fullscreen: when any non-minimized window on active workspace is fullscreen
This feature requires compositor support for ext-workspace-v1 protocol
to correctly track workspace membership. Without it, classes fall back
to the active application state only.
Also includes active-only option implementation.
Changes:
- Add ext-workspace-v1 protocol support for workspace tracking
- Implement WorkspaceState tracking in Taskbar class
- Add workspace management lifecycle (create/remove/done)
- Add bar CSS class update logic with aggregation
- Add visible() getter to Task class
- Implement active-only task visibility control
- Update man page with documentation and CSS examples
