LGUG2Z 62e37e44cf feat(kwin): workspaces are KWin's own desktops
komorebi's workspaces exist on Windows and macOS because neither has a virtual
desktop API: switching hides every window of the workspace being left. KWin has
virtual desktops, per output since 6.8, so here workspace i is KWin's desktop i
on every monitor, and each monitor shows one. KWin shows, hides and focuses the
windows of a desktop; komorebi asks for a switch, puts a window on a desktop,
and follows what anything else does.

The Backend gets the workspace methods (ensure_workspaces, switch_workspace,
set_window_workspace, window_workspace, current_workspaces), and the fake its
desktops. The bridge reports the desktops, the desktop each output shows and a
window's desktops, and carries out output_desktop and desktop commands, typed
and tested with the fixtures like the rest. The table turns a switch or a move
komorebi did not make into a WorkspaceChange or a WorkspaceMove, and records its
own when it sends them, so that KWin's report of those raises nothing. The
window manager follows a switch with no command in reply
(adopt_workspace_change), puts windows on their desktops before a desktop is
shown (focusing a window first would take the monitor back), and loads the
windows open at startup onto the workspace of their desktop.

Per-output desktops are a kwinrc setting that is off by default, and
kwriteconfig6 was not on the PATH of the user service in a live session, so
komorebi edits kwinrc itself (kwin::kwinrc) and puts the user's value back when
it stops, also after a crash.

focus-workspace, move-to-workspace and send-to-workspace come with this commit,
since the tests of switching and moving, and vm-workspace-switch, need them; the
named and cycling workspace commands follow. vm-workspace-switch runs the daemon
against a real KWin; vm-kwin-contract checks what komorebi relies on from KWin's
per-output desktops, on a headless KWin with two outputs and no komorebi.

komorebi for KDE

Overview

komorebi is a tiling window manager for KDE Plasma on Wayland. It decides where each window goes, and KWin, the window manager of Plasma, moves and draws the windows.

komorebi is a daemon that runs in the background, and it is controlled with a CLI, komorebic. Every komorebic command that asks something of the daemon is a message on its socket, so anything that can run a command can drive komorebi: a terminal, a script, or a program that binds keys, which is how a key is given an action.

komorebi aims to make as few modifications as possible to the operating system and desktop environment by default. Users are free to make such modifications in their own configuration files for komorebi, but these will always remain opt-in and off-by-default.

How it fits together

komorebi only responds to the events KWin reports about windows and to the messages it receives on a dedicated socket. komorebic is a CLI that writes messages on komorebi's socket. komorebi doesn't handle any keyboard or mouse inputs: a program that binds keys, such as the custom shortcuts in Plasma's System Settings, runs komorebic commands.

Getting started

Installing komorebi explains how to install the two programs: on NixOS with the flake's module, which also starts komorebi with every Plasma session, and from source anywhere else. Running komorebi explains how to start and stop the daemon, ask it what it is doing and read its log. Focusing windows explains how to give the focus to another window, Moving windows how to move the focused window to another tile, Layouts how to change the arrangement of the tiles, Resizing windows how to change the size of one, Floating windows how to take a window out of the layout, Managing windows how to minimize, close and unmanage the focused window and pause the daemon, and Padding and work area offsets how to put gaps around the tiles and keep parts of a monitor free of them. Rules explains how to keep an application out of the layout, always tile it, or float its windows. Workspaces explains how each monitor shows one of its workspaces, which are KWin's virtual desktops, and how to show another or move a window to one. Subscribing to notifications explains how a program such as a status bar follows what komorebi does. The CLI reference has a page for every komorebic command, generated from its help.

Community

There is a Discord server available for komorebi-related discussion, help, troubleshooting etc.

There is a YouTube channel where I post komorebi development videos, feature previews and release overviews. Subscribing to the channel (which is monetized as part of the YouTube Partner Program) and watching videos is a really simple and passive way to contribute financially to the development and maintenance of komorebi.

There is an Awesome List which showcases the many awesome projects that exist in the komorebi ecosystem.
