# Bspwm

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 or bspwm-git from the AUR. You will also want to install sxhkd or sxhkd-git, a simple X hotkey daemon used to communicate with bspwm through `bspc` as well as launch your applications of choice.

To start bspwm on login, add the following to `~/.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`.

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

Documentation for bspwm is found by running `man bspwm`.

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

#### Note for multi-monitor setups

The example bspwmrc configures ten desktops on one monitor like this:

    bspc monitor -d I II III IV V VI VII VIII IX X

You will need to change this line and add one for each monitor, similar to this:

    bspc monitor DVI-I-1 -d I II III IV
    bspc monitor DVI-I-2 -d V VI VII
    bspc monitor DP-1 -d VIII IX X

You can use `xrandr -q` or `bspc query -M` to find the monitor names.

The total number of desktops were maintained at ten in the above example. This is so that each desktop can still be addressed with 'super + {1-9,0}' in the sxhkdrc.

### Rules

There are two ways to set window rules (as of cd97a32).

The first is by using the built in rule command, as shown in the example bspwmrc:

    bspc rule -a Gimp desktop=^8 follow=on floating=on
    bspc rule -a Chromium desktop=^2
    bspc rule -a mplayer2 floating=on
    bspc rule -a Kupfer.py focus=on
    bspc rule -a Screenkey manage=off

The second option is to use an external rule command. This is more complex, but can allow you to craft more complex window rules. See these examples for a sample rule command. These scripts require lua-posix, lua and xwinfo.

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 &

## Troubleshooting

### Help! I get a blank screen and my keybindings don't work!

There are a few ways to debug this. First, a blank screen is good. That means bspwm is running.

I would confirm that your xinitrc looks something like

    sxhkd &
    exec bspwm

The ampersand is important. Next, try spawning a terminal in your xinitrc to see if its getting positioned properly. It should appear somewhat "centered" on the screen. To do this, use this .xinitrc:

    sxhkd &
    urxvt &
    exec bspwm

If nothing shows up, that means you probably forgot to install urxvt. If it shows up but isn't centered or taking up most of your screen, that means BSPWM isn't getting started properly. Make sure that you've `chmod +x ~/.config/bspwm/bspwmrc` .

Next, type pidof sxhkd in that terminal you spawned. It should return a number. If it doesn't, that means sxhd isn't running. Try to be explicit and run `sxhkd -c ~/.config/sxhkd/sxhkdrc` . You could also try changing the Super key to something like Alt in your sxhkdrc and see if that helps. Another common problem is copying the text from the example files instead of physically copying the file over. Copying / pasting code usually leads to indentation issues which sxhkd can be sensitive to.

### Window box larger than the actual application!

This can happen if you are using GTK3 apps and usually for dialog windows. The fix is to add the below to the gtk3 theme file (../gtk-3.0/gtk.css).

    .window-frame, .window-frame:backdrop {
      box-shadow: 0 0 0 black;
      border-style: none;
      margin: 0;
      border-radius: 0;
    }

    .titlebar {
      border-radius: 0;
    }
