BSPWM

PRIMARY CATEGORY → SETUP

bspwm → Binary Space Partitioning Window Manager

bspwm is launched as a process and It receives as an argument a socket on which to listen

$ pgrep --list-full --exact bspwm
2604 bspwm -s /tmp/bspwm_0_0-state -o 4 # Note -s option argument

$ file /tmp/bspwm_0_0-socket
/tmp/bspwm_0_0-socket: socket

bspc binary writes messages to bspwm’s socket. Those messages are all the commands executed in bspwmrc init file

$ command -V bspc
bspc is /usr/local/bin/bspc

IMPORTANT

Note that bspwm does not handle any input since its fd 0 is pointing to /dev/null

$ file /proc/$( pgrep --exact bspwm )/fd/0
/proc/2604/fd/0: symbolic link to /dev/null

Thus, sxhkd translate keyboard and pointers events to bspc

sxhkd process listens to an input event and executes the command related to it. It can be any command, most of them are the bspc ones that write to bspwm’s socket

That sxhkd’s input event is usually a keyboard shortcut

This Windows Manager generates and divides each OS Window in half (Binary Partitioning)

OS Windows Layouts/States

There are several types of OS Windows Layouts →

• Tiled
• Monocle
• Floating
• Full-Screen

Configuration File → ~/.config/bspwm/bspwmrc

More information here

Installation

First of all, install the following requirements →

$ sudo apt install -y -- build-essential git vim xcb libxcb-util0-dev libxcb-ewmh-dev libxcb-randr0-dev libxcb-icccm4-dev libxcb-keysyms1-dev libxcb-xinerama0-dev libasound2-dev libxcb-xtest0-dev libxcb-shape0-dev

Clone the bspwm’s Github Repository →

$ cd ~/Downloads
$ git clone https://github.com/baskerville/bspwm.git bspwm

$ cd !$ # cd ~/Downloads/bspwm
$ make
$ sudo make install

That’s it

$ command -V bspwm
bspwm is /usr/local/bin/bspwm

Configuration Files

Create the ~/.config/bspwm directory and store the bspwmrc configuration file in it

$ mkdir -p ~/.config/bspwm
$ cp ~/Downloads/bspwm/examples/bspwmrc !$

Source/Binary Files

Same as above, but as follows →

$ mkdir -p ~/.config/bspwm/{bin,src}

$ touch ~/.config/bspwm/bin/bspwm_resize.sh
$ chmod +x !$

$ touch ~/.config/bspwm/src/bspwmrc.sh

Just copy the following files’ content and paste into the above created ones →

• bspwmrc.sh → Source File
• bspwm_resize.sh → Binary File

---

Configuration Files

IMPORTANT

bspwmrc file is executed with the following command by lightdm process →

$ bspwm -c /path/to/bspwmrc

Therefore, the shell interpreter that executes bspwmrc is the one indicated by the shebang

It’s recommended to use a POSIX Compliant shell such as sh or dash

#!/usr/bin/env sh 

#!/usr/bin/env dash

Two files are required →

• ~/.config/bspwm/bspwmrc → bspwm’s Configuration File
• ~/.config/bspwm/src/bspwmrc.sh → bspwmrc sources it

bspwmrc

Binary Files

One file is required →

• ~/.config/bspwm/bin/bspwm_resize.sh → sxhkd relates a specific input event (Hotkey) to this script execution

bin/bspwm_resize.sh
