Hyprland exposes 2 UNIX Sockets, for controlling / getting info about Hyprland
|
|
via code / bash utilities.
|
|
|
|
## Hyprland Instance Signature (HIS)
|
|
|
|
```sh
|
|
echo $HYPRLAND_INSTANCE_SIGNATURE
|
|
```
|
|
|
|
## /tmp/hypr/\[HIS\]/.socket.sock
|
|
|
|
Used for hyprctl-like requests. See the
|
|
[Hyprctl page](../Configuring/Using-hyprctl) for commands.
|
|
|
|
basically, write `[flag(s)]/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`
|
|
|
|

{{< callout type=warning >}}

|
|
|
A fullscreen event is not guaranteed to fire on/off once in succession. Some windows
|
|
may fire multiple requests to be fullscreened, resulting in multiple
|
|
fullscreen events.

## How to use socket2 with bash
|
|
|
|
Example script using socket2 events with bash and `socat`:
|
|
|
|
```sh
|
|
#!/bin/sh
|
|
|
|
handle() {
|
|
case $1 in
|
|
monitoradded*) do_something ;;
|
|
focusedmon*) do_something_else ;;
|
|
esac
|
|
}
|
|
|
|
socat -U - UNIX-CONNECT:/tmp/hypr/$HYPRLAND_INSTANCE_SIGNATURE/.socket2.sock | while read -r line; do handle "$line"; done
|
|
```
