Little Wing

Little Wing is a bitboard chess engine.

It has been a work in progress since 2014 and the library is not stabilized yet, but the goal is to have an engine with modern algorithms, a simple API and a great CLI with support for XBoard and UCI protocols.

Example

use littlewing::game::Game;
use littlewing::fen::FEN;
use littlewing::clock::Clock;
use littlewing::search::Search;
use littlewing::moves_generator::MovesGenerator;

// Byrne vs Fischer (1956)
let fen = "r3r1k1/pp3pbp/1Bp1b1p1/8/2BP4/Q1n2N2/P4PPP/3R1K1R b - - 0 18";

let mut game = Game::from_fen(fen);

game.clock = Clock::new(1, 5000); // Search 1 move in 5 seconds

match game.search(1..15) { // Search from depth 1 to 15
    Some(m) => {
        assert_eq!(game.move_to_san(m), "Bxc4");

        game.make_move(m);
        game.history.push(m); // Keep track of the moves played

        println!("Engine played {}", m.to_can());
    },
    None => {
        println!("Engine could not find a move to play");
    }
}
