k_board

A lightweight keyboard mannager developed for dynamic programs by listening to keyboard events in raw mode (without the need to press enter). The handler has all the standard events of a western keyboard.

Only for Gnu/Linux distributions

pub enum Keys {
    Up,
    Down,
    Left,
    Right,
    Enter,
    Space,
    Delete,
    Escape,
    Char(char)
    F(u8),
    Ctrl(char),
    Alt(char),
    AltGr(char),
    Null,
}

Examples

Arrows keys & enter for dynamic menus

Simply cargo add k_board. No features.

use k_board::{keyboard::Keyboard, keys::Keys};

fn main() {
    menu(0);
    let keyboard = Keyboard::new();
    for key in keyboard {
        match key {
            Keys::Up => menu(0),
            Keys::Down => menu(1),
            Keys::Enter => break,
            _ => {}
        }
    }
}

fn menu(operation: u8) {
    std::process::Command::new("clear").status().unwrap();
    let mut op: Vec<char> = vec!['*', ' '];
    if operation == 1 {
        op[0] = ' ';
        op[1] = '*';
    }
    println!(
        "[{}] I use k_board lightweight software\n[{}] I use heavyweight software",
        op[0], op[1]
    );
}

Why k_board?

k_board, is designed for low-level development (direct interaction with the OS), boasts high and efficient performance compared to other libraries dedicated to keyboard interaction. This is demonstrated by performance tests conducted and that you can also perform to verify the technical superiority of this crate.

This has allowed k_board to be lighter than keyboard handling libraries without sacrificing quality and adding in-depth control to the developer over which part of the keyboard to manage and which not to.
