## Description
-`bspwm` is a tiling window manager based on binary space partitioning.
-
-The windows are represented as the leaves of a binary tree.
-
-## Configuration
-
-`bspwm` have only two sources of informations: the X events it receives and the messages it reads on a dedicated socket.
-
-Those messages are sent via `bspc`.
-
-If the `BSPWM_SOCKET` environment variable is defined, it will be used as the socket path, otherwise `/tmp/bspwm-socket` is used.
-
-The recommended way of defining keyboard shortcuts is to use [sxhkd](https://github.com/baskerville/sxhkd).
-
-The only way to configure `bspwm` is by sending *set* messages via the client, hence `bspwm`'s configuration file is an executable called `autostart` which lives in `$XDG_CONFIG_HOME/bspwm/`.
-
-Example configurations: [autostart](https://github.com/baskerville/bin/blob/master/bspwm_autostart) and [sxhkdrc](https://github.com/baskerville/dotfiles/blob/master/sxhkdrc).
-
-## 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 |

-## Synopsis
-
- bspwm [-v|-s STATUS_FIFO]
-
- bspc MESSAGE [ARGUMENTS] [OPTIONS]
-
-## Messages
+*bspwm* is a tiling window manager that represents windows as the leaves of a full binary tree.
-The syntax for the client is `bspc MESSAGE [ARGUMENTS ...]`.
+It only responds to X events, and the messages it receives on a dedicated socket.
-The following messages are handled:
+*bspc* is a program that writes messages on *bspwm*'s socket.
- get SETTING
- Return the value of the given setting.
+*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.
- set SETTING VALUE
- Set the value of the given setting.
+The outlined architecture is the following:
- list [DESKTOP_NAME]
- Output the internal representation of the window tree.
+```

+## Monitors, desktops and windows
- use DESKTOP_NAME
- Select the given desktop.
+*bspwm* holds a list of monitors.
- use_monitor MONITOR_NAME
- Select the given monitor.
+A monitor is just a rectangle that contains desktops.
- alternate
- Alternate between the current and the last focused window.
+A desktop is just a pointer to a tree.
- alternate_desktop
- Alternate between the current and the last focused desktop.
+Monitors only show the tree of one desktop at a time (their focused desktop).
- alternate_monitor
- Alternate between the current and the last focused monitor.
+The tree is a partition of a monitor's rectangle into smaller rectangular regions.
- add DESKTOP_NAME ...
- Make new desktops with the given names.
+Each node in a tree either has zero or two children.
- add_in MONITOR_NAME DESKTOP_NAME ...
- Make new desktops with the given names in the given monitor.
+Each internal node is responsible for splitting a rectangle in half.
- rename_monitor CURRENT_NAME NEW_NAME
- Rename the monitor named CURRENT_NAME to NEW_NAME.
+A split is defined by two parameters: the type (horizontal or vertical) and the ratio (a real number *r* such that *0 < r < 1*).
- rename CURRENT_NAME NEW_NAME
- Rename the desktop named CURRENT_NAME to NEW_NAME.
+Each leaf node holds exactly one window.
- cycle_monitor next|prev
- Select the next or previous monitor.
+## Insertion Modes
- cycle_desktop next|prev [--skip-free|--skip-occupied]
- Select the next or previous desktop.
+### Prelude
- layout monocle|tiled [DESKTOP_NAME ...]
- Set the layout of the given desktops (current if none given).
+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.
- cycle_layout
- Cycle the layout of the current desktop.
+The insertion mode tells *bspwm* how it should alter the tree in order to insert new windows on a given insertion point.
- rotate clockwise|counter_clockwise|full_cycle
- Rotate the tree of the current desktop.
+By default the insertion point is the focused window and its insertion mode is *automatic*.
- rule PATTERN [DESKTOP_NAME] [floating]
- Create a new rule (PATTERN must match the class or instance name).
+### Manual Mode
- remove_rule UID ...
- Remove the rules with the given UIDs.
+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*).
- reload_autostart
- Reload the autostart file.
+After doing so the insertion point goes into *manual* mode.
- reload_settings
- Reload the default settings.
+Let's consider the following scenario:
- restore FILE_PATH
- Restore the layout of each desktop from the content of FILE_PATH.

-## Settings
+ X Y Z
+```
-Colors are either [X color names](http://en.wikipedia.org/wiki/X11_color_names) or *#RRGGBB*, booleans are *true* or *false*.
+In state *X*, the insertion point is *1*.
- focused_border_color
- Color of the main border of a focused window of a focused monitor.
+We send the following message to *bspwm*: *node -p north*.
- active_border_color
- Color of the main border of a focused window of an unfocused monitor.
+Then add a new window: *4*, this leads to state *Y*: the new internal node, *c* becomes *a*'s first child.
- normal_border_color
- Color of the main border of an unfocused window.
+Finally we send another message: *node -p west* and add window *5*.
- inner_border_color
- Color of the inner border of a 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.
- outer_border_color
- Color of the outer border of a window.
+### Automatic Mode
- presel_border_color
- Color of the *presel* message feedback.
+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.
- focused_locked_border_color
- Color of the main border of a focused locked window of a focused monitor.
+#### Longest side
- active_locked_border_color
- Color of the main border of a focused locked window of an unfocused monitor.
+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 choosen based on the dimensions of the tiling rectangle and the initial polarity.
- normal_locked_border_color
- Color of the main border of an unfocused locked window.
+Let's consider the following scenario, where the initial polarity is set to `second_child`:
- urgent_border_color
- Color of the border of an urgent window.
+```
+ 1 a a
+ ^ / \ / \
+ ---> 1 2 ---> 1 b
+ ^ / \
+ 2 3
+ ^
- inner_border_width
- main_border_width
- outer_border_width
- Width of the inner, main and outer borders.

- window_gap
- Value of the gap that separates windows.
+ X Y Z
+```
- {top,right,bottom,left}_padding
- Padding space added at the sides of the current monitor.
+In state *X*, a new window is added.
- wm_name
- The value that shall be used for the _NET_WM_NAME property of the root window.
+Since *1* is wide, it gets split vertically and *2* is added as *a*'s second child given the initial polarity.
- borderless_monocle
- Whether to remove borders for tiled windows in monocle mode.
+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.
- gapless_monocle
- Whether to remove gaps for tiled windows in monocle mode.
+#### Spiral
- focus_follows_mouse
- Wether to focus the window under the mouse pointer.
+When the value of the automatic scheme is `spiral`, the window will *take the space* of the insertion point.
- adaptative_raise
- Prevent floating windows from being raised when they might cover other floating windows.
+Let's dive into the details with the following scenario:

-## Panel
+ X Y Z
+```
-Multiple choices:
-- `dzen2` fed with the output of `ewmhstatus`. Example: [launchpanel](https://github.com/baskerville/bin/blob/master/launchpanel).
-- A custom panel if the `-s` flag is used (have a look at the files in `examples/`).
-- Any EWMH compliant panel (e.g. `tint2`, `bmpanel2`, etc.).
+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.
