Global shortcuts using evdev
shortcutd is a daemon and client library to allow listening for global shortcuts for systems that don't support it otherwise (such as wayland).
The shortcutd daemon hooks into the evdev system and exposes a dbus interface for clients to hook into to. By separating out the code that hooks into evdev (which needs to be done as root) into a separate daemon it allows non-privileged users to hook into global shortcuts.
Protection against clients using the shortcutd daemon for a keylogger is done by only allowing 3 shortcuts without modifiers to be registered at the same time.
nl.icewind.shortcutd.conf
into /etc/dbus-1/system.d/
```rust use futures::{pin_mut, StreamExt}; use shortcutd::{Shortcut, ShortcutClient}; use std::error::Error;
async fn main() -> Result<(), Box
let shortcut: Shortcut = "<Ctrl><Alt>-KeyO".parse()?;
let stream = client.listen(shortcut).await?;
pin_mut!(stream);
while let Some(event) = stream.next().await {
println!("{} {}", event.shortcut, event.state);
}
Ok(())
}
```
Register
method at nl.icewind.shortcutd
/register
listen to the signal at the path returned from the Register
method to get notified when the shortcut is triggered.
A boolean parameter is provided with the signal to distinguish shortcut presses from releases.
