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` # Events list | name | description | data | | --- | --- | --- | | workspace | emitted on workspace change. Is emitted ONLY when a user requests a workspace change, and is not emitted on mouse movements (see `activemon`) | `WORKSPACENAME` | | focusedmon | emitted on the active monitor being changed. | `MONNAME,WORKSPACENAME` | | activewindow | emitted on the active window being changed. | `WINDOWCLASS,WINDOWTITLE` | | activewindowv2 | emitted on the active window being changed. | `WINDOWADDRESS` | | fullscreen | emitted when a fullscreen status of a window changes. | `0/1` (exit fullscreen / enter fullscreen) | | monitorremoved | emitted when a monitor is removed (disconnected) | `MONITORNAME` | | monitoradded | emitted when a monitor is added (connected) | `MONITORNAME` | | createworkspace | emitted when a workspace is created | `WORKSPACENAME` | | destroyworkspace | emitted when a workspace is destroyed | `WORKSPACENAME` | | moveworkspace | emitted when a workspace is moved to a different monitor | `WORKSPACENAME,MONNAME` | | activelayout | emitted on a layout change of the active keyboard | `KEYBOARDNAME,LAYOUTNAME` | | openwindow | emitted when a window is opened | `WINDOWADDRESS`,`WORKSPACENAME`,`WINDOWCLASS`,`WINDOWTITLE` | | closewindow | emitted when a window is closed | `WINDOWADDRESS` | | movewindow | emitted when a window is moved to a workspace | `WINDOWADDRESS`,`WORKSPACENAME` | | openlayer | emitted when a layerSurface is mapped | `NAMESPACE` | | closelayer | emitted when a layerSurface is unmapped | `NAMESPACE` | | submap | emitted when a keybind submap changes. Empty means default. |`SUBMAPNAME` | | changefloatingmode | emitted when a window changes its floating mode. `FLOATING` is either 0 or 1. | `WINDOWADDRESS`,`FLOATING` | | urgent | emitted when a window requests an `urgent` state | `WINDOWADDRESS` | | minimize | emitted when a window requests a change to its minimized state. `MINIMIZED` is either 0 or 1. | `WINDOWADDRESS,MINIMIZED` | | screencopy | emitted when a screencopy state of a client changes. Keep in mind there might be multiple separate clients. State is 0/1, owner is 0 - monitor share, 1 - window share | `STATE,OWNER` | {{< hint type=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. {{< /hint >}} # How to use socket2 with bash example script using socket2 events with bash and `socat`: ```sh #!/bin/sh function handle { if [[ ${1:0:12} == "monitoradded" ]]; then # do_something fi } socat -U - UNIX-CONNECT:/tmp/hypr/$(echo $HYPRLAND_INSTANCE_SIGNATURE)/.socket2.sock | while read line; do handle $line; done ```
