+## Description
-## Synopsis
+*bspwm* is a tiling window manager that represents windows as the leaves of a full binary tree.
- bspwm [-h|-v|-s PANEL_FIFO|-p PANEL_PREFIX]
+It only responds to X events, and the messages it receives on a dedicated socket.
- bspc MESSAGE [ARGUMENTS] [OPTIONS]
+*bspc* is a program that writes messages on *bspwm*'s socket.
-## Description
+*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.
-`bspwm` is a tiling window manager that represents windows as the leaves of a full binary tree.
+The outlined architecture is the following:
-It is controlled and configured via `bspc`.
+```
+ PROCESS SOCKET
+sxhkd --------> bspc <------> bspwm
+```
## Configuration
-`bspwm` have only two sources of informations: the X events it receives and the messages it reads on a dedicated socket.
+The default configuration file is `$XDG_CONFIG_HOME/bspwm/bspwmrc`: this is simply a shell script that calls *bspc*.
-Its configuration file is `$XDG_CONFIG_HOME/bspwm/autostart`.
+An argument is passed to that script to indicate whether is was executed after a restart (`$1 -gt 0`) or not (`$1 -eq 0`).
Keyboard and pointer bindings are defined with [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 |

+## Monitors, desktops and windows
-- `remove_desktop DESKTOP_NAME ...` — Remove the given desktops.
+*bspwm* holds a list of monitors.
-- `send_desktop_to MONITOR_NAME [--follow]` — Send the current desktop to the given monitor.
+A monitor is just a rectangle that contains desktops.
-- `cycle_monitor next|prev` — Select the next or previous monitor.
+A desktop is just a pointer to a tree.
-- `cycle_desktop next|prev [--skip-free|--skip-occupied]` — Select the next or previous desktop.
+Monitors only show the tree of one desktop at a time (their focused desktop).
-- `layout monocle|tiled [DESKTOP_NAME ...]` — Set the layout of the given desktops (current if none given).
+The tree is a partition of a monitor's rectangle into smaller rectangular regions.
-- `cycle_layout` — Cycle the layout of the current desktop.
+Each node in a tree either has zero or two children.
-- `rotate clockwise|counter_clockwise|full_cycle` — Rotate the window tree.
+Each internal node is responsible for splitting a rectangle in half.
-- `flip horizontal|vertical` — Flip the window tree.
+A split is defined by two parameters: the type (horizontal or vertical) and the ratio (a real number *r* such that *0 < r < 1*).
-- `balance` — Adjust the split ratios so that all windows occupy the same area.
+Each leaf node holds exactly one window.
-- `rule PATTERN [DESKTOP_NAME] [floating] [follow]` — Create a new rule (`PATTERN` must match the class or instance name).
+## Insertion modes
-- `remove_rule UID ...` — Remove the rules with the given UIDs.
+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.
-- `put_status` — Output the current state to the panel fifo.
+The insertion mode tells *bspwm* how it should alter the tree in order to insert new windows on a given insertion point.
-- `adopt_orphans` — Manage all the unmanaged windows remaining from a previous session.
+By default the insertion point is the focused window and its insertion mode is *automatic*.
-- `restore_layout FILE_PATH` — Restore the layout of each desktop from the content of `FILE_PATH`.
+### Manual mode
-- `restore_history FILE_PATH` — Restore the history of each desktop from the content of `FILE_PATH`.
+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*.
-- `quit [EXIT_STATUS]` — Quit.
+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*).
-## Settings
+After doing so the insertion point goes into *manual* mode.
-Colors are either [X color names](http://en.wikipedia.org/wiki/X11_color_names) or *#RRGGBB*, booleans are *true* or *false*.
+Let's consider the following scenario:
-All the boolean settings are *false* by default.
+```
+ a a a
+ / \ / \ / \
+ 1 b ---> c b ---> c b
+ ^ / \ / \ / \ / \ / \
+ 2 3 4 1 2 3 d 1 2 3

-- `focused_border_color` — Color of the border of a focused window of a focused monitor.

-- `active_border_color` — Color of the border of a focused window of an unfocused monitor.
+ X Y Z
+```
-- `normal_border_color` — Color of the border of an unfocused window.
+In state *X*, the insertion point is *1*.
-- `presel_border_color` — Color of the `presel` message feedback.
+We send the following message to *bspwm*: *node -p north*.
-- `focused_locked_border_color` — Color of the border of a focused locked window of a focused monitor.
+Then add a new window: *4*, this leads to state *Y*: the new internal node, *c* becomes *a*'s first child.
-- `active_locked_border_color` — Color of the border of a focused locked window of an unfocused monitor.
+Finally we send another message: *node -p west* and add window *5*.
-- `normal_locked_border_color` — Color of the border of an unfocused locked window.
+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.
-- `urgent_border_color` — Color of the border of an urgent window.
+### Automatic mode
-- `border_width` — Window border width.
+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.
-- `window_gap` — Value of the gap that separates windows.
+#### Longest side scheme
-- `split_ratio` — Default split ratio.
+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.
-- `{top,right,bottom,left}_padding` — Padding space added at the sides of the current monitor.
+Let's consider the following scenario, where the initial polarity is set to `second_child`:
-- `wm_name` — The value that shall be used for the `_NET_WM_NAME` property of the root window.
+```
+ 1 a a
+ ^ / \ / \
+ ---> 1 2 ---> 1 b
+ ^ / \
+ 2 3

-- `borderless_monocle` — Remove borders for tiled windows in monocle mode.
+ +-----------------------+ +-----------------------+ +-----------------------+
+ | | | | | | | |
+ | | | | | | | 2 |

+ +-----------------------+ +-----------------------+ +-----------------------+
-- `gapless_monocle` — Remove gaps for tiled windows in monocle mode.
+ X Y Z
+```
-- `focus_follows_pointer` — Focus the window under the pointer.
+In state *X*, a new window is added.
-- `pointer_follows_monitor` — When focusing a monitor, put the pointer at its center.
+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` — 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` — 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
+```

-- Configured and controlled through messages.
-- Multiple monitors support (via *RandR*).
-- 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`).
+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.
