-## Synopsis
-
- bspwm [-v|-s STATUS_FIFO]
-
- 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 |
- | | | | | |

-- `shift left|right|up|down` — Exchange the current window with the given neighbor.

+The outlined architecture is the following:
-- `push left|right|up|down` — Push the fence located in the given direction.

+A monitor is just a rectangle that contains desktops.

+A desktop is just a pointer to a tree.
-- `quit [EXIT_STATUS]` — Quit.
+Monitors only show the tree of one desktop at a time (their focused desktop).
-## Settings
+The tree is a partition of a monitor's rectangle into smaller rectangular regions.
-Colors are either [X color names](http://en.wikipedia.org/wiki/X11_color_names) or *#RRGGBB*, booleans are *true* or *false*.
+Each node in a tree either has zero or two children.
-- `focused_border_color` — Color of the border of a focused window of a focused monitor.
+Each internal node is responsible for splitting a rectangle in half.
-- `active_border_color` — Color of the border of a focused window of an unfocused monitor.
+A split is defined by two parameters: the type (horizontal or vertical) and the ratio (a real number *r* such that *0 < r < 1*).
-- `normal_border_color` — Color of the border of an unfocused window.
+Each leaf node holds exactly one window.
-- `presel_border_color` — Color of the `presel` message feedback.
+## Insertion Modes
-- `focused_locked_border_color` — Color of the border of a focused locked window of a focused monitor.
+### Prelude
-- `active_locked_border_color` — Color of the border of a focused locked window of an unfocused monitor.
+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.
-- `normal_locked_border_color` — Color of the border of an unfocused locked window.
+The insertion mode tells *bspwm* how it should alter the tree in order to insert new windows on a given insertion point.
-- `urgent_border_color` — Color of the border of an urgent window.
+By default the insertion point is the focused window and its default insertion mode is *automatic*.
-- `border_width` — Window border width.
+### Automatic Mode
-- `window_gap` — Value of the gap that separates windows.
+The *automatic* mode, as opposed to the *manual* mode, doesn't require any user choice: the new window will *take the space* of the insertion point.
-- `{top,right,bottom,left}_padding` — Padding space added at the sides of the current monitor.
+For example, let's consider the following scenario:
-- `wm_name` — The value that shall be used for the `_NET_WM_NAME` property of the root window.
+```
+ a a a
+ / \ / \ / \
+ 1 b ---> 1 c ---> 1 d
+ / \ / \ / \
+ 2 3 4 b 5 c
+ ^ ^ / \ ^ / \
+ 3 2 b 4
+ / \
+ 3 2
-- `borderless_monocle` — Whether to remove borders for tiled windows in monocle mode.
+ +-----------------------+ +-----------------------+ +-----------------------+
+ | | | | | | | | |
+ | | 2 | | | 4 | | | 5 |
+ | | ^ | | | ^ | | | ^ |
+ | 1 |-----------| | 1 |-----------| | 1 |-----------|
+ | | | | | | | | | 3 | |
+ | | 3 | | | 3 | 2 | | |-----| 4 |
+ | | | | | | | | | 2 | |
+ +-----------------------+ +-----------------------+ +-----------------------+
-- `gapless_monocle` — Whether to remove gaps for tiled windows in monocle mode.
+ X Y Z
+```
-- `focus_follows_pointer` — Whether to focus the window under the pointer.
+In state *X*, the insertion point, *2* is in automatic mode.
-- `adaptative_raise` — Prevent floating windows from being raised when they might cover other floating windows.
+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*.
-- `apply_shadow_property` — Enable shadows for floating windows via the `_COMPTON_SHADOW` property.
+The splitting parameters of *b* (type: *horizontal*, ratio: *½*) are copied to *c* and *b* is rotated by 90° clockwise.
-- `auto_alternate` — Whether to interpret two consecutive identical `use` messages as an `alternate` message.
+The tiling rectangle of *4* in state *Y* is equal to the tiling rectangle of *2* in state *X*.
-## Environment Variables
+Then the insertion of *5*, with *4* as insertion point, leads to *Z*.
-- `BSPWM_SOCKET` — The path of the socket used for the communication between `bspc` and `bspwm`.
+The automatic mode generates window spirals that rotate clockwise (resp. anti-clockwise) if the insertion point is the first (resp. second) child of its parent.
-## Key Features
+### Manual Mode
-- Configured and controlled through messages.
-- Multiple monitors support (via *Xinerama*).
-- EWMH support (`tint2` works).
-- Automatic and manual modes.
+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*.
-## Panels
+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*).
-- 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).
+After doing so the insertion point goes into *manual* mode.
-## Required Libraries:
+For example, let's consider the following scenario:
-- libxcb
-- xcb-util
-- xcb-util-wm
+```
+ a a a
+ / \ / \ / \
+ 1 b ---> c b ---> c b
+ ^ / \ / \ / \ / \ / \
+ 2 3 4 1 2 3 d 1 2 3
+ ^ / \
+ 5 4
+ ^

-## Contributors
+In state *X*, the insertion point is *1*.
-- [Ivan Kanakarakis](https://github.com/c00kiemon5ter)
+We send the following message to *bspwm*: *node -p north*.
-- [Thomas Adam](https://github.com/ThomasAdam)
+Then add a new window: *4*, this leads to state *Y*: the new internal node, *c* becomes *a*'s first child.
-## Mailing List
+Finally we send another message: *node -p west* and add window *5*.
-bspwm *at* librelist *dot* com.
+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.
