device_query

NOTE: This repository has been relocated to https://codeberg.org/ostrosco/device_query. Future work will continue there.

A simple library to query mouse and keyboard inputs on demand without a window. Will work in Windows, Linux on X11, and macOS.

use device_query::{DeviceQuery, DeviceState, MouseState, Keycode};

let device_state = DeviceState::new();
let mouse: MouseState = device_state.get_mouse();
println!("Current Mouse Coordinates: {:?}", mouse.coords);
let keys: Vec = device_state.get_keys();
println!("Is A pressed? {}", keys.contains(Keycode::A));

Dependencies

Windows shouldn't require any special software to be installed for device_query to work properly. On Linux, the X11 development libraries are required for device_query to query state from the OS.

On Ubuntu/Debian:

sudo apt install libx11-dev

On Fedora/RHEL/CentOS:

sudo dnf install xorg-x11-server-devel

On newer versions of MacOS, you may run into issues where you only see meta keys such as shift, backspace, et cetera. This is due to a permission issue. To work around this:

• open the MacOS system preferences
• go to Security -> Privacy
• scroll down to Accessibility and unlock it
• add the app that is using device_query (such as your terminal) to the list

Device Callbacks

device_query allows you to register callbacks for various device events such as key presses and mouse movements.

Example

Here's a simple example demonstrating how to use the callback system:
