polybar-sxhkd

• Read sxhkd status and display the label of hotkey chain

Require

• sxhkd-statusd
  • Get from here
• socat (tested on version 1.7.3.4)
• bash (tested on GNU bash version 5.0.7)
  • Need to support the associative array feature (at least bash version 4)

Usage

• Download the script and put it in path you want.

• Make the named pipe to write sxhkd status

  • $ mkfifo /run/user/$UID/sxhkd.fifo

• Run sxhkd with the status pipe.

  • $ sxhkd -s /run/user/$UID/sxhkd.fifo &

• Run sxhkd-statusd with the sxhkd status pipe

  • $ sxhkd-statusd /run/user/$UID/sxhkd.fifo &

• Open the script, and modify ADDRESS in the configuration section to the socket path.

  • The socket path is the same as sxhkd status pipe, with suffix .sxhkd-statusd.
  • declare -r ADDRESS="/run/user/$UID/sxhkd.fifo.sxhkd-statusd"

• Edit the other configuration in the script for your customization.

• Add this module in your polybar config, and reload polybar.

[module/sxhkd]
type = custom/script
tail = true
label = %output%
exec = /path/of/the/script.sh

Configuration section

• Configuration is stored directly in the script

ADDRESS

• The full path of sxhkd-statusd socket.
  • The path is the same as sxhkd status pipe, with suffix .sxhkd-statusd.
  • declare -r ADDRESS="/run/user/$UID/sxhkd.fifo.sxhkd-statusd"

LABEL

• When you have started hotkey chain, the script will display the label.

LABEL_PREFIX, LABEL_SUFFIX

• Prefix and suffix of the label. it is useful for formatting the label.

LABEL_TABLE

• Assigned label list for each hotkey, as the ["key"]="value" format

key

• H + the prefix of hotkey chain to display, including all whitespace.
• single prefix example:
  • 'Hsuper + m' can be used for super + m; in sxhkdrc
• chained prefix example:
  • 'Hsuper + m; n; o' for super + m; n; o;
• branched chain example:
  • 'Hsuper + m; n; o' can be used also, when super + {m,M}; {n,N}; {o,O}; is written in sxhkdrc.
• all whitespaces are not trimmed, including the last whitespaces.
  • When the hotkey is written as super + m ; in sxhkdrc, 'super + m' may not be recognized.
  • Because, there is one whitespace between m and ; in sxhkdrc. key in LABEL_TABLE should be 'super + m '

value

• The label for the hotkey. it will be displayed actually.

Script section

• The actual script is written in this. if you are familiar with bash, you can edit it yourself.
