# My BSPWM Configuration

![Screenshot of my desktop](https://www.gitlab.com/dwt1/dotfiles/raw/master/.screenshots/dotfiles08.png)

*bspwm* is a tiling window manager that represents windows as the leaves of a full binary tree.

It only responds to X events, and the messages it receives on a dedicated socket.

*bspc* is a program that writes messages on *bspwm*'s socket.

*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.

The outlined architecture is the following:

```
        PROCESS          SOCKET
sxhkd  -------->  bspc  <------>  bspwm
```

## Configuration

The default configuration file is `$XDG_CONFIG_HOME/bspwm/bspwmrc`: this is simply a shell script that calls *bspc*.

Keyboard and pointer bindings are defined with [sxhkd](https://github.com/baskerville/sxhkd).

Example configuration files can be found in the [examples](https://github.com/baskerville/bspwm/blob/master/examples) directory.

## Monitors, desktops and windows

*bspwm* holds a list of monitors.

A monitor is just a rectangle that contains desktops.

A desktop is just a pointer to a tree.

Monitors only show the tree of one desktop at a time (their focused desktop).

The tree is a partition of a monitor's rectangle into smaller rectangular regions.

Each node in a tree either has zero or two children.

Each internal node is responsible for splitting a rectangle in half.

A split is defined by two parameters: the type (horizontal or vertical) and the ratio (a real number *r* such that *0 < r < 1*).

Each leaf node holds exactly one window.

# My Keybindings (defined by sxhkd)

The keybindings for bspwm are controlled by another program called sxhkd.  You will find my sxhkdrc here: https://gitlab.com/dwt1/dotfiles/blob/master/.config/sxhkd/sxhkdrc

The MODKEY is set to the Super key (aka the Windows key).

| Keybinding | Action |
| :--- | :--- |
| `ALT + CRTL + Enter` | opens run launcher (dmenu is the run launcher but can be easily changed) |
| `MODKEY + Enter` | opens terminal (st is the terminal but can be easily changed) |
| `MODKEY + SHIFT + c` | closes window with focus |
| `MODKEY + Esc` | reloads the bspwm conifguration file |
| `MODKEY + SHIFT + r` | restarts bspwm |
| `MODKEY + SHIFT + q` | quits bspwm |
| `MODKEY + j` | switches focus between windows in the stack, going down |
| `MODKEY + k` | switches focus between windows in the stack, going up |
| `MODKEY + SHIFT + j` | rotates the windows in the stack, going down|
| `MODKEY + SHIFT + k` | rotates the windows in the stack, going up |
| `MODKEY + t` | set window state to tiled |
| `MODKEY + s` | set window state to pseudo-tiled |
| `MODKEY + f` | set window state to floating |
| `MODKEY + 1-9` | switch focus to workspace (1-9) |
| `MODKEY + SHIFT + 1-9` | sends focused window to workspace (1-9) |
