- bspc MESSAGE [ARGUMENTS] [OPTIONS]
-
## Description
-`bspwm` is a tiling window manager where each window is represented as the leaf of a binary tree.
-
-It is controlled and configured via `bspc`.
-
-## Configuration
-
-`bspwm` have only two sources of informations: the X events it receives and the messages it reads on a dedicated socket.
-
-Its configuration file is `$XDG_CONFIG_HOME/bspwm/autostart`.
-
-Keyboard and pointer bindings are defined through [sxhkd](https://github.com/baskerville/sxhkd).
-
-Example configuration files can be found in the `examples` directory.
-
-## Splitting Modes
-
-There is only two splitting modes: *automatic* and *manual*.
-
-The default mode is *automatic*. The *manual* mode is entered by sending a *presel* message.
-
-Example: insertion of a new node (number 4) into the given tree in
-*automatic* mode:
-
- b c
- / \ / \
- 3 a --> 4 b
- ^ / \ ^ / \
- 2 1 3 a
- / \
- 2 1
- +-------------------------+ +-------------------------+
- | | | | | |
- | | 2 | | | 3 |
- | | | | | |
- | 3 |------------| --> | 4 |------------|
- | ^ | | | ^ | | |
- | | 1 | | | 1 | 2 |
- | | | | | | |
- +-------------------------+ +-------------------------+
-
-Same departure, but the mode is *manual*, and a `presel up` message
-was sent beforehand:
-
- b b
- / \ / \
- 3 a --> c a
- ^ / \ / \ / \
- 2 1 4 3 2 1
- ^
- +-------------------------+ +-------------------------+
- | | | | | |
- | | 2 | | 4 | 2 |
- | | | | ^ | |
- | 3 |------------| --> |------------|------------|
- | ^ | | | | |
- | | 1 | | 3 | 1 |

-## Messages
-
-The syntax for the client is `bspc MESSAGE [ARGUMENTS ...]`.
-
-The following messages are handled:
-
-- `get SETTING` — Return the value of the given setting.
-
-- `set SETTING VALUE` — Set the value of the given setting.
-
-- `list [DESKTOP_NAME]` — Output the internal representation of the window tree.
+*bspwm* is a tiling window manager that represents windows as the leaves of a full binary tree.
-- `list_desktops [--quiet]` — Perform a dump of each desktop for the current monitor.
+It only responds to X events, and the messages it receives on a dedicated socket.
-- `list_monitors [--quiet]` — Perform a dump of each monitor.
+*bspc* is a program that writes messages on *bspwm*'s socket.
-- `list_history` — Return the node focus history of each desktop.
+*bspwm* doesn't handle any keyboard or pointer inputs: a third party program (e.g. *sxhkd*) is needed in order to translate keyboard and pointer events to *bspc* invocations.
-- `list_windows` — Return the list of managed windows (i.e. their identifiers).
+The outlined architecture is the following:
-- `list_rules` — Return the list of rules.

+## Configuration
-- `drop_to_monitor next|prev [--follow]` — Send the focused window to the next or previous monitor.
+The default configuration file is `$XDG_CONFIG_HOME/bspwm/bspwmrc`: this is simply a shell script that calls *bspc*.
-- `use DESKTOP_NAME` — Select the given desktop.
+An argument is passed to that script to indicate whether is was executed after a restart (`$1 -gt 0`) or not (`$1 -eq 0`).
-- `use_monitor MONITOR_NAME` — Select the given monitor.
+Keyboard and pointer bindings are defined with [sxhkd](https://github.com/baskerville/sxhkd).
-- `alternate` — Alternate between the current and the last focused window.
+Example configuration files can be found in the [examples](examples) directory.
-- `alternate_desktop` — Alternate between the current and the last focused desktop.
+## Monitors, desktops and windows
-- `alternate_monitor` — Alternate between the current and the last focused monitor.
+*bspwm* holds a list of monitors.
-- `add DESKTOP_NAME ...` — Make new desktops with the given names.
+A monitor is just a rectangle that contains desktops.
-- `add_in MONITOR_NAME DESKTOP_NAME ...` — Make new desktops with the given names in the given monitor.
+A desktop is just a pointer to a tree.
-- `rename_monitor CURRENT_NAME NEW_NAME` — Rename the monitor named `CURRENT_NAME` to `NEW_NAME`.
+Monitors only show the tree of one desktop at a time (their focused desktop).
-- `rename CURRENT_NAME NEW_NAME` — Rename the desktop named `CURRENT_NAME` to `NEW_NAME`.
+The tree is a partition of a monitor's rectangle into smaller rectangular regions.
-- `cycle_monitor next|prev` — Select the next or previous monitor.
+Each node in a tree either has zero or two children.
-- `cycle_desktop next|prev [--skip-free|--skip-occupied]` — Select the next or previous desktop.
+Each internal node is responsible for splitting a rectangle in half.
-- `layout monocle|tiled [DESKTOP_NAME ...]` — Set the layout of the given desktops (current if none given).
+A split is defined by two parameters: the type (horizontal or vertical) and the ratio (a real number *r* such that *0 < r < 1*).
-- `cycle_layout` — Cycle the layout of the current desktop.
+Each leaf node holds exactly one window.
-- `rotate clockwise|counter_clockwise|full_cycle` — Rotate the window tree.
+## Insertion modes
-- `flip horizontal|vertical` — Flip the window tree.
+When *bspwm* receives a new window, it inserts it into a window tree at the specified insertion point (a leaf) using the insertion mode specified for that insertion point.
-- `balance` — Adjust the split ratios so that all windows occupy the same area.
+The insertion mode tells *bspwm* how it should alter the tree in order to insert new windows on a given insertion point.
-- `rule PATTERN [DESKTOP_NAME] [floating] [follow]` — Create a new rule (`PATTERN` must match the class or instance name).
+By default the insertion point is the focused window and its insertion mode is *automatic*.
-- `remove_rule UID ...` — Remove the rules with the given UIDs.
+### Manual mode
-- `put_status` — Output the current state to the panel fifo.
+The user can specify a region in the insertion point where the next new window should appear by sending a *node -p|--presel-dir DIR* message to *bspwm*.
-- `adopt_orphans` — Manage all the unmanaged windows remaining from a previous session.
+The *DIR* argument allows to specify how the insertion point should be split (horizontally or vertically) and if the new window should be the first or the second child of the new internal node (the insertion point will become its *brother*).
-- `restore FILE_PATH` — Restore the layout of each desktop from the content of `FILE_PATH`.
+After doing so the insertion point goes into *manual* mode.
-- `quit [EXIT_STATUS]` — Quit.
+Let's consider the following scenario:
-## Settings
+```
+ a a a
+ / \ / \ / \
+ 1 b ---> c b ---> c b
+ ^ / \ / \ / \ / \ / \
+ 2 3 4 1 2 3 d 1 2 3
+ ^ / \
+ 5 4
+ ^
-Colors are either [X color names](http://en.wikipedia.org/wiki/X11_color_names) or *#RRGGBB*, booleans are *true* or *false*.

-- `focused_border_color` — Color of the border of a focused window of a focused monitor.
+ X Y Z
+```
-- `active_border_color` — Color of the border of a focused window of an unfocused monitor.
+In state *X*, the insertion point is *1*.
-- `normal_border_color` — Color of the border of an unfocused window.
+We send the following message to *bspwm*: *node -p north*.
-- `presel_border_color` — Color of the `presel` message feedback.
+Then add a new window: *4*, this leads to state *Y*: the new internal node, *c* becomes *a*'s first child.
-- `focused_locked_border_color` — Color of the border of a focused locked window of a focused monitor.
+Finally we send another message: *node -p west* and add window *5*.
-- `active_locked_border_color` — Color of the border of a focused locked window of an unfocused monitor.
+The ratio of the preselection (that ends up being the ratio of the split of the new internal node) can be changed with the *node -o|--presel-ratio* message.
-- `normal_locked_border_color` — Color of the border of an unfocused locked window.
+### Automatic mode
-- `urgent_border_color` — Color of the border of an urgent window.
+The *automatic* mode, as opposed to the *manual* mode, doesn't require any user choice. The way the new window is inserted is determined by the value of the automatic scheme and the initial polarity settings.
-- `border_width` — Window border width.
+#### Longest side scheme
-- `window_gap` — Value of the gap that separates windows.
+When the value of the automatic scheme is `longest_side`, the window will be attached as if the insertion point was in manual mode and the split direction was chosen based on the dimensions of the tiling rectangle and the initial polarity.
-- `split_ratio` — Default split ratio.
+Let's consider the following scenario, where the initial polarity is set to `second_child`:
-- `{top,right,bottom,left}_padding` — Padding space added at the sides of the current monitor.
+```
+ 1 a a
+ ^ / \ / \
+ ---> 1 2 ---> 1 b
+ ^ / \
+ 2 3
+ ^
-- `wm_name` — The value that shall be used for the `_NET_WM_NAME` property of the root window.
+ +-----------------------+ +-----------------------+ +-----------------------+
+ | | | | | | | |
+ | | | | | | | 2 |

+ +-----------------------+ +-----------------------+ +-----------------------+
-- `borderless_monocle` — Whether to remove borders for tiled windows in monocle mode.
+ X Y Z
+```
-- `gapless_monocle` — Whether to remove gaps for tiled windows in monocle mode.
+In state *X*, a new window is added.
-- `focus_follows_pointer` — Whether to focus the window under the pointer.
+Since *1* is wide, it gets split vertically and *2* is added as *a*'s second child given the initial polarity.
-- `adaptative_raise` — Prevent floating windows from being raised when they might cover other floating windows.
+This leads to *Y* where we insert window *3*. *2* is tall and is therefore split horizontally. *3* is once again added as *b*'s second child.
-- `apply_shadow_property` — Enable shadows for floating windows via the `_COMPTON_SHADOW` property.
+#### Alternate scheme
-- `auto_alternate` — Whether to interpret two consecutive identical `use` messages as an `alternate` message.
+When the value of the automatic scheme is `alternate`, the window will be attached as if the insertion point was in manual mode and the split direction was chosen based on the split type of the insertion point's parent and the initial polarity. If the parent is split horizontally, the insertion point will be split vertically and vice versa.
-- `focus_by_distance` — Whether to use window or leaf distance for focus movement.
+#### Spiral scheme
-## Environment Variables
+When the value of the automatic scheme is `spiral`, the window will *take the space* of the insertion point.
-- `BSPWM_SOCKET` — The path of the socket used for the communication between `bspc` and `bspwm`.
+Let's dive into the details with the following scenario:
-## Key Features
+```
+ a a a
+ / \ / \ / \
+ 1 b ---> 1 c ---> 1 d
+ / \ / \ / \

-- Configured and controlled through messages.
-- Multiple monitors support (via *Xinerama*).
-- EWMH support (`tint2` works).
-- Automatic and manual modes.

-## Panels
+ X Y Z
+```
-- Any EWMH compliant panel (e.g. `tint2`, `bmpanel2`, etc.).
-- A custom panel if the `-s` flag is used (have a look at the files in `examples/panel`).
-- `dzen2` fed with the output of `ewmhstatus`. Example: [launchpanel](https://github.com/baskerville/bin/blob/master/launchpanel).
+In state *X*, the insertion point, *2* is in automatic mode.
-## Required Libraries:
+When we add a new window, *4*, the whole tree rooted at *b* is reattached, as the second child of a new internal node, *c*.
-- libxcb
-- xcb-util
-- xcb-util-wm
+The splitting parameters of *b* (type: *horizontal*, ratio: *½*) are copied to *c* and *b* is rotated by 90° clockwise.
-## Installation
+The tiling rectangle of *4* in state *Y* is equal to the tiling rectangle of *2* in state *X*.
- make
- make install
+Then the insertion of *5*, with *4* as insertion point, leads to *Z*.
-## Contributors
+The *spiral* automatic scheme generates window spirals that rotate clockwise (resp. anti-clockwise) if the insertion point is the first (resp. second) child of its parent.
