Crossterm Input

The crossterm_input crate is deprecated and no longer maintained. The GitHub repository will be archived soon. All the code is being moved to the crossterm crate. You can learn more in the Merge sub-crates to the crossterm crate issue.

This crate allows you to read the user input cross-platform. It supports all UNIX and Windows terminals down to Windows 7 (not all terminals are tested see Tested Terminals for more info).

crossterm_input is a sub-crate of the crossterm crate. You can use it directly, but it's highly recommended to use the crossterm crate with the input feature enabled.

• Detailed documentation
• Few dependencies

[dependencies]
# All crossterm features are enabled by default.
crossterm = "0.11"

use crossterm::{input, InputEvent, KeyEvent, MouseButton, MouseEvent, RawScreen, Result};

fn main() -> Result<()> {
    // Keep _raw around, raw mode will be disabled on the _raw is dropped
    let _raw = RawScreen::into_raw_mode()?;

    let input = input();
    input.enable_mouse_mode()?;

    let mut sync_stdin = input.read_sync();

    loop {
        if let Some(event) = sync_stdin.next() {
            match event {
                InputEvent::Keyboard(KeyEvent::Esc) => break,
                InputEvent::Keyboard(KeyEvent::Left) => println!("Left arrow"),
                InputEvent::Mouse(MouseEvent::Press(MouseButton::Left, col, row)) => {
                    println!("Left mouse button pressed at {}x{}", col, row);
                }
                _ => println!("Other event {:?}", event),
            }
        }
    }

    input.disable_mouse_mode()
} // <- _raw dropped = raw mode disabled
