Hyprland exposes 2 UNIX Sockets, for controlling / getting info about Hyprland via code / bash utilities.
Hyprland Instance Signature (HIS)
echo $HYPRLAND_INSTANCE_SIGNATURE
/tmp/hypr/[HIS]/.socket.sock
Used for hyprctl-like requests. See the Hyprctl page for commands.
basically, write command args
.
/tmp/hypr/[HIS]/.socket2.sock
Used for events. Hyprland will write to each connected client live events like this:
EVENT>>DATA\n
(\n is a linebreak)
e.g.: workspace>>2
Events list:
workspace
emitted on workspace change. Is emitted ONLY when a user requests a workspace
change, and is not emitted on mouse movements (see activemon
)
Data: WORKSPACENAME
focusedmon
emitted on the active monitor being changed.
Data: MONNAME,WORKSPACENAME
activewindow
emitted on the active window being changed.
Data: WINDOWCLASS,WINDOWTITLE
fullscreen
emitted when a fullscreen status of a window changes.
Warning: a fullscreen event is not guaranteed to fire on/off once in succession. A window might do for example 3 requests to be fullscreen'd, which would result in 3 fullscreen events.
Data: 0/1 (exit fullscreen / enter fullscreen)
monitorremoved
emitted when a monitor is removed (disconnected)
Data: MONITORNAME
monitoradded
emitted when a monitor is added (connected)
Data: MONITORNAME
createworkspace and destroyworkspace
emitted when a workspace is created or removed
Data: WORKSPANCENAME
How to use socket2 with bash
example script using socket2 events with bash and socat
:
#!/bin/sh
function handle {
if [[ ${1:0:12} == "monitoradded" ]]; then
# do_something
fi
}
socat - UNIX-CONNECT:/tmp/hypr/$(echo $HYPRLAND_INSTANCE_SIGNATURE)/.socket2.sock | while read line; do handle $line; done
