# rofi-actions(5)
|
||
|
|
|
||
|
|
## NAME
|
||
|
|
|
||
|
|
**rofi-actions** - Custom commands following interaction with rofi menus
|
||
|
|
|
||
|
|
## DESCRIPTION
|
||
|
|
|
||
|
|
**rofi** allows to set custom commands or scripts to be executed when some actions are performed in the menu, such as changing selection, accepting an entry or canceling.
|
||
|
|
|
||
|
|
This makes it possible for example to play sound effects or read aloud menu entries on selection.
|
||
|
|
|
||
|
|
## USAGE
|
||
|
|
|
||
|
|
Following is the list of rofi flags for specifying custom commands or scripts to execute on supported actions:
|
||
|
|
|
||
|
|
`-on-selection-changed` *cmd*
|
||
|
|
|
||
|
|
Command or script to run when the current selection changes. Selected text is forwarded to the command replacing the pattern *{entry}*.
|
||
|
|
|
||
|
|
`-on-entry-accepted` *cmd*
|
||
|
|
|
||
|
|
Command or script to run when a menu entry is accepted. Accepted text is forwarded to the command replacing the pattern *{entry}*.
|
||
|
|
|
||
|
|
`-on-mode-changed` *cmd*
|
||
|
|
|
||
|
|
Command or script to run when the menu mode (e.g. drun,window,ssh...) is changed.
|
||
|
|
|
||
|
|
`-on-menu-canceled` *cmd*
|
||
|
|
|
||
|
|
Command or script to run when the menu is canceled.
|
||
|
|
|
||
|
|
`-on-menu-error` *cmd*
|
||
|
|
|
||
|
|
Command or script to run when an error menu is shown (e.g. `rofi -e "error message"`). Error text is forwarded to the command replacing the pattern *{error}*.
|
||
|
|
|
||
|
|
`-on-screenshot-taken` *cmd*
|
||
|
|
|
||
|
|
Command or script to run when a screenshot of rofi is taken. Screenshot path is forwarded to the command replacing the pattern *{path}*.
|
||
|
|
|
||
|
|
### Example usage
|
||
|
|
|
||
|
|
Rofi command line:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
rofi -on-selection-changed "/path/to/select.sh {entry}" \
|
||
|
|
-on-entry-accepted "/path/to/accept.sh {entry}" \
|
||
|
|
-on-menu-canceled "/path/to/exit.sh" \
|
||
|
|
-on-mode-changed "/path/to/change.sh" \
|
||
|
|
-on-menu-error "/path/to/error.sh {error}" \
|
||
|
|
-on-screenshot-taken "/path/to/camera.sh {path}" \
|
||
|
|
-show drun
|
||
|
|
```
|
||
|
|
|
||
|
|
Rofi config file:
|
||
|
|
|
||
|
|
```css
|
||
|
|
configuration {
|
||
|
|
on-selection-changed: "/path/to/select.sh {entry}";
|
||
|
|
on-entry-accepted: "/path/to/accept.sh {entry}";
|
||
|
|
on-menu-canceled: "/path/to/exit.sh";
|
||
|
|
on-mode-changed: "/path/to/change.sh";
|
||
|
|
on-menu-error: "/path/to/error.sh {error}";
|
||
|
|
on-screenshot-taken: "/path/to/camera.sh {path}";
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
### Play sound effects
|
||
|
|
|
||
|
|
Here's an example bash script that plays a sound effect using `aplay` when the current selection is changed:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
#!/bin/bash
|
||
|
|
|
||
|
|
coproc aplay -q $HOME/Music/selecting_an_item.wav
|
||
|
|
```
|
||
|
|
|
||
|
|
The use of `coproc` for playing sounds is suggested, otherwise the rofi process will wait for sounds to end playback before exiting.
|
||
|
|
|
||
|
|
### Read aloud
|
||
|
|
|
||
|
|
Here's an example bash script that reads aloud currently selected entries using `espeak`:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
#!/bin/bash
|
||
|
|
|
||
|
|
killall espeak
|
||
|
|
echo "selected: $@" | espeak
|
||
|
|
```
