A small Rust library that lets you get position, size, title and a few other properties of the active window on Windows, MacOS and Linux

[dependencies]
active-win-pos-rs = "0.9"

use active_win_pos_rs::get_active_window;

fn main() {
    match get_active_window() {
        Ok(active_window) => {
            println!("active window: {:#?}", active_window);
        },
        Err(()) => {
            println!("error occurred while getting the active window");
        }
    }
}

Would give you an instance of ActiveWindow struct with unique window id, process id, window position and window title.

Or use active_win_pos_rs::get_position to get the WindowPosition only.

On MacOS title property will always return an empty string unless you Enable Screen Recording permission for your app.

% git clone https://github.com/dimusic/active-win-pos-rs.git
% cd active-win-pos-rs
% cargo build

% cargo run --example active-window

Output:

active window: ActiveWindow {
    title: "cmd - cargo  run --example active-window",
    process_path: "C:\\Program Files\\WindowsApps\\Microsoft.WindowsTerminal_1.16.10262.0_x64__8wekyb3d8bbwe\\WindowsTerminal.exe",
    app_name: "WindowsTerminal",
    window_id: "HWND(9700584)",
    process_id: 8460,
    position: WindowPosition {
        x: 6.0,
        y: 296.0,
        width: 1129.0,
        height: 635.0,
    },
}
