//! `komorebic`, the command line interface of komorebi for KDE Plasma.
//!
//! A subcommand that asks something of the daemon is one message on its socket: an order, such as
//! `stop` or `retile`, is written and `komorebic` exits; a question, such as `state` or `query`,
//! is written and the answer is printed. The messages are [`komorebi_client::SocketMessage`]s,
//! sent with [`komorebi_client::send_message`] and [`komorebi_client::send_query`].
//!
//! The orders that change what the daemon tiles:
//!
//! - `focus` and `cycle-focus` give the focus to another window of the focused workspace, and
//!   `mouse-follows-focus` and `toggle-mouse-follows-focus` set whether the pointer goes with it.
//! - `move` and `cycle-move` move the focused window to another tile.
//! - `change-layout`, `cycle-layout` and `flip-layout` change the layout of the focused
//!   workspace, `scrolling-layout-columns` and `layout-ratios` tune it, `toggle-tiling` turns its
//!   tiling off and on, and `preselect-direction` and `cancel-preselect` reserve the place of the
//!   next window and give it up.
//! - `consume`, `expel` and `toggle-column-stack` put windows in the same column of the Scrolling
//!   layout and take them out, `scrolling-layout-full-width`, `center-focus` and `expand` make the
//!   focused column as wide as the screen, put it in the middle and fill the room that is left,
//!   and `pan` moves the view along the strip without moving the focus.
//! - `stack` puts the focused window in one container with the window on one side of it, so that
//!   they share a tile and only one is in sight, `unstack` takes it out again, and `stack-all` and
//!   `unstack-all` do it for the whole workspace and for the focused stack. `cycle-stack` brings
//!   the next or the previous window of the focused stack to the front, `cycle-stack-index` moves
//!   the front window along the stack, and `focus-stack-window` brings the window at an index to
//!   the front. `toggle-window-container-behaviour` and
//!   `toggle-workspace-window-container-behaviour` make a window that opens join the focused
//!   container instead of getting a tile, and `toggle-float-override` and
//!   `toggle-workspace-float-override` make it float.
//! - `promote`, `promote-swap`, `promote-focus` and `promote-window` bring a window to the largest
//!   tile, or the focus to it.
//! - `toggle-float` takes the focused window out of the layout, or puts it back,
//!   `toggle-workspace-layer` switches the focused workspace between its tiled windows and its
//!   floating ones, and `toggle-lock` locks the focused container at its index, or unlocks it.
//! - `toggle-monocle` gives the focused container the whole work area, or puts it back, and
//!   `monocle-focus-behaviour` and `toggle-monocle-focus-behaviour` set what focusing in a
//!   direction does meanwhile. `toggle-maximize` has KWin maximize the focused window, which
//!   leaves the layout, and restores it.
//! - `focused-workspace-padding`, `focused-workspace-container-padding`, `workspace-padding`,
//!   `container-padding` and the two `adjust-*-padding` set the padding around the tiles and
//!   between them, and `global-work-area-offset`, `monitor-work-area-offset`,
//!   `workspace-work-area-offset` and `toggle-window-based-work-area-offset` keep parts of the work
//!   area free of tiles.
//! - `minimize` and `close` minimize and close the focused window, `unmanage` takes it out of
//!   the layout until `manage` takes it back, `unmanaged-window-operation-behaviour` sets whether
//!   the daemon carries out an order while the focused window is not one it tiles, and
//!   `toggle-pause` pauses the daemon and resumes it.
//! - `resize-edge` and `resize-axis` resize the focused window by the `resize-delta`, and
//!   `quick-save-resize`, `quick-load-resize`, `save-resize` and `load-resize` save the sizes of
//!   the tiles of the focused workspace and load them back.
//! - `focus-workspace` shows another workspace of the focused monitor, `move-to-workspace` moves
//!   the focused window to a workspace and shows it, and `send-to-workspace` moves it there and
//!   stays. A workspace is KWin's virtual desktop of the same number, counted from 0.
//!   `cycle-workspace`, `cycle-empty-workspace`, `cycle-move-to-workspace` and
//!   `cycle-send-to-workspace` go to the next or the previous workspace, `focus-last-workspace`,
//!   `move-to-last-workspace` and `send-to-last-workspace` to the one that was in front before,
//!   `focus-workspaces` shows a workspace on every monitor, and `new-workspace` and
//!   `close-workspace` add a workspace and remove an empty one.
//! - `focus-monitor`, `cycle-monitor` and `focus-monitor-at-cursor` focus another monitor, and
//!   `focus-monitor-workspace` a workspace of another monitor; `move-to-monitor`,
//!   `send-to-monitor`, their `cycle-` forms, `move-to-monitor-workspace`,
//!   `send-to-monitor-workspace`, `move-to-named-workspace` and `send-to-named-workspace` take the
//!   focused window to another monitor; `move-workspace-to-monitor`,
//!   `cycle-move-workspace-to-monitor` and `swap-workspaces-with-monitor` take workspaces there;
//!   `cross-monitor-move-behaviour` and `toggle-cross-monitor-move-behaviour` set what `move` does
//!   at the edge of a monitor, and `display-index-preference` gives a monitor an index.
//!   `eager-focus` focuses the first window of an executable, on any workspace of any monitor.
//! - `workspace-name` names a workspace, which `focus-named-workspace`, `named-workspace-layout`,
//!   `named-workspace-tiling`, `named-workspace-padding` and `named-workspace-container-padding`
//!   find by its name; `workspace-layout` and `workspace-tiling` set the layout and the tiling of
//!   a workspace by its index, and `ensure-workspaces` and `ensure-named-workspaces` give a
//!   monitor workspaces up to a number, or with names.
//! - `border` sets whether the compositor draws a border around each window, `border-colour` the
//!   color of the border of a kind of window, and `border-width` and `border-offset` the room the
//!   layout leaves for it.
//! - `focus-follows-mouse` and `toggle-focus-follows-mouse` set whether KWin gives the focus to the
//!   window under the pointer, as the pointer moves.
//! - `transparency` and `toggle-transparency` set whether the windows that do not have the focus
//!   are see-through, and `transparency-alpha` how opaque they are.
//! - `animation`, `animation-duration` and `animation-style` set whether windows are animated going
//!   to their places, for how long and with what easing, and `animation-fps` the frame rate that
//!   is stored and ignored.
//!
//! `ignore-rule` and `manage-rule` add a rule that keeps an application out of the layout or
//! always in it, `session-float-rule` floats the focused window and every window like it until the
//! daemon stops, `session-float-rules` shows those rules and `clear-session-float-rules` removes
//! them, and `global-state` shows the rules the daemon has. `visible-windows` shows the windows
//! that can be seen on the workspace each monitor shows.
//!
//! `initial-workspace-rule`, `initial-named-workspace-rule`, `workspace-rule` and
//! `named-workspace-rule` send the windows of an application to a workspace, when they open or
//! always, `clear-workspace-rules`, `clear-named-workspace-rules` and `clear-all-workspace-rules`
//! take those rules away, and `enforce-workspace-rules` applies them to the windows that are open.
//!
//! `workspace-layout-rule` and `named-workspace-layout-rule` make a workspace change layout once
//! it has so many windows, and `clear-workspace-layout-rules` and
//! `clear-named-workspace-layout-rules` take those rules away. `generate-static-config` prints the
//! settings of the daemon as a `komorebi.json`, and `replace-configuration` makes the daemon
//! start over with another one.
//!
//! `subscribe-socket` and `unsubscribe-socket` add and remove a subscriber: a program that listens
//! on a socket in the daemon's data directory, to which the daemon sends a notification after each
//! event and each message it handles.
//!
//! The others work without the daemon: `quickstart` writes an example `komorebi.json`,
//! `applications.json` and `skhdrc` in the config home, `enable-autostart` and `disable-autostart` write and
//! remove the entry that has Plasma start komorebi at login, `start` runs `komorebi` in the
//! background, with the `komorebi.json` it is given with `--config`, `check` reads the
//! `komorebi.json` the daemon would and the key binding file, looks at the desktop, and reports
//! what is wrong, exiting with status 1 if something is an error, `configuration` shows the path
//! of the `komorebi.json` the daemon reads, `log` follows its log, `data-directory` shows where its
//! socket is, `completions` prints a completion script for a shell, and `static-config-schema`,
//! `application-specific-configuration-schema`, `notification-schema` and `socket-schema` print
//! the JSON Schema of `komorebi.json`, of an `applications.json`, of a notification and of a
//! message. The hidden `docgen` writes the help of every subcommand as Markdown, wrapped
//! at 100 columns whatever the width of the terminal, which is how `docs/cli` is made.
//!
//! `export-kde-shortcuts` and `hotkeys compile` read a key binding file (an skhdrc, a whkdrc or an
//! sxhkdrc) and write the bindings KDE can run by itself as shortcut files. `hotkeys state`,
//! `hotkeys reload` and `hotkeys release` look after the keys the daemon registers with KDE; the
//! [`hotkeys`] module has the details.
