bspwm is a tiling window manager that represents windows as the leaves of a full binary tree. It has support for EWMH and multiple monitors, and is configured and controlled through messages.

Installation

Install bspwm^AUR or bspwm-git^AUR from the AUR. You will also want to install sxhkd^AUR or sxhkd-git^AUR, a simple X hotkey daemon used to communicate with bspwm through bspc as well as launch your applications of choice. With commit 948b804, xwinfo-git^AUR is also required by the example configuration files.

To start bspwm on login, add the following to your .xinitrc:

sxhkd &
exec bspwm

Configuration

Example configuration is found on GitHub.

Copy bspwmrc to ~/.config/bspwm/bspwmrc, sxhkdrc to ~/.config/sxhkd/sxhkdrc and make bspwmrc executable with chmod +x ~/.config/bspwm/bspwmrc.

Documentation for bspwm is found by running man bspwm.

There is also documentation for sxhkd found by running man sxhkd.

These two files are where you will be setting wm settings and keybindings, respectively.

Rules

As of 948b804 window-specific rules were externalized. Rules can be created in a few different ways. Two such methods are below:

1. Using the example scripts provide in rules, place rulc and ruld in a folder that is in your $PATH and make them executable. Start ruld on login with something like rulc -l > /dev/null || ruld &. You can then use the rules in the example bspwmrc These scripts require both lua-posix and lua
2. Alternatively, create a script that is called in your bspwmrc file that forms the rules. See Stebalien's post or earsplit's config for examples of how to accomplish this.

Both of these methods require installing xwinfo from the AUR or from github

If a particular window does not seem to be behaving according to your rules, check the class name of the program. This can be accomplished by running xprop | grep WM_CLASS to make sure you're using the proper string.

Panels

Currently, bar and dzen2 are supported with bspwm. Check the examples folder on the GitHub page for ideas or the Bar wiki page. The panel will be executed by placing panel & for bar or panel dzen2 & for dzen2 in your bspwmrc. Check the opt-depends in the bspwm package for dependencies that may be required in either case.

To display system information on your status bar you can use various system calls. This example will show you how to edit your panel to get the volume status on your BAR:

panel_volume()
{
        volStatus=$(amixer get Master | tail -n 1 | cut -d '[' -f 4 | sed 's/].*//g')
        volLevel=$(amixer get Master | tail -n 1 | cut -d '[' -f 2 | sed 's/%.*//g')
        # is alsa muted or not muted?
        if [ "$volStatus" == "on" ]
        then
                echo "\f6"$volLevel
        else
                # If it is muted, make the font red
                echo "\f1"$volLevel
        fi
}

Next, we will have to make sure it is called and piped to $PANEL_FIFO:

while true; do
echo "S" "$(panel_volume) $(panel_clock) > "$PANEL_FIFO"
        sleep 1s
done &

Example how to configure after install

1. Copy the supplied bspwm_rules, rule_command, ruld and rulc scripts from Examples to $XDG_CONFIG_HOME/bspwm/ and ensure they are executable.

2. Edit $HOME/.profile to something similar to this:

PATH="/usr/games:$HOME/.config/bspwm:$PATH"

export XDG_CONFIG_HOME="/home/$USER/.config"

## Bspwm
export BSPWM_SOCKET="/tmp/bspwm-socket"
export BSPWM_TREE=/tmp/bspwm.tree
export BSPWM_HISTORY=/tmp/bspwm.history
export BSPWM_STACK=/tmp/bspwm.stack
export PANEL_FIFO=/tmp/panel-fifo
export PANEL_HEIGHT=14

3. Edit $HOME/.xinitrc and add.

source $HOME/.profile &
sxhkd -c $XDG_CONFIG_HOME/bspwm/sxhkdrc &
exec wm 

4. Add this line to $XDG_CONFIG_HOME/bspwm/bspwmrc.

bspc config rule_command "$(command -v rule_command)"

5. Install xwinfo from AUR and lua-posix. Change the rules of $XDG_CONFIG_HOME/bspwm/bspwm_rules to your likening.

$ man bspc

...
rule_command
External command used to retrieve rule consequences. The command will receive the the ID of the
window being processed as its first argument. The output of that command must have the following
format: key1=value1 key2=value2 ..., where keyN is one of floating, fullscreen, locked, sticky,
private, frame, center, lower, follow, manage, focus, desktop or monitor.
...

To find out the window names you can use xorg-xprop. The lower-case 'vlc' is the instance and the upper-case 'Vlc' is the class.

$ xprop | grep WM_CLASS

WM_CLASS(STRING) = "vlc", "Vlc"

6. Restart bspwm and check so the rules have been applied.

$ rulc -l

class == "Gimp" =>floating=on
class == "Firefox" => desktop=^2
class == "Vlc" => desktop=^3
instance == "rtorrent" => desktop=^3
instance == "URthree" => desktop=^3

Troubleshooting

The following environmental variables may need to be defined:

echo $BSPWM_SOCKET
echo $XDG_CONFIG_HOME

If either of these do not respond with a value, then go to your ~/.profile and add the following lines:

export XDG_CONFIG_HOME="$HOME/.config"
export BSPWM_SOCKET="/tmp/bspwm-socket"
