Example: visualising a chess board

extern crate matrix_display;
use matrix_display::*;

fn main() {
    let format = Format::new(7, 3);
	let board = vec!['♜', '♞', '♝', '♛', '♚', '♝', '♞', '♜',
	                 '♟', '♟', '♟', '♟', '♟', '♟', '♟', '♟',
					 ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ',
                     ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ',
					 ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ',
					 ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ',
					 '♖', '♘', '♗', '♕', '♔', '♗', '♘', '♖',
					 '♙', '♙', '♙', '♙', '♙', '♙', '♙', '♙']
        .iter()
        .enumerate()
		.map(|(i, x)| {
            let ansi_fg = 33;
			let mut ansi_bg = 0;
		    if i % 2 + (i / 8) % 2 == 1 {
			    ansi_bg = 7;
			}
		    cell::Cell::new(x.clone(), ansi_fg, ansi_bg)
			})
        .collect::<Vec<_>>();
    let data = matrix::Matrix::new(8, board);
    let display = MatrixDisplay::new(format, data);
	display.cell_at_cursor_position((13, 6)).color.bg = 10;
    display.print(&mut std::io::stdout(), &style::BordersStyle::None);
}

Example: visualising a 2048 game

extern crate matrix_display;
use matrix_display::*;

fn main() {
    let format = Format::new(7, 3);
    let colour_theme = vec![247, 78, 222, 220, 214, 208, 202, 196, 162, 160, 126, 90, 88, 54, 53, 52];
    let board = (0..16)
        .map(|x| {
            cell::Cell::new(2_f64.powi(x + 1),
                      7,
                      *colour_theme.get(x as usize).unwrap() as u8)
        })
        .collect::<Vec<_>>();
    let data = matrix::Matrix::new(4, board);
    let display = MatrixDisplay::new(format, data);
    display.print(&mut std::io::stdout(), &style::BordersStyle::Thick);
}

For a working version of the game, see 2048-rs

Example: visualising a 256 colors palette

extern crate matrix_display;
use matrix_display::*;

fn main() {
    let format = Format::new(5, 1);
    let board = (0..256)
        .map(|x| cell::Cell::new(x, 0, x as u8))
        .collect::<Vec<_>>();
    let data = matrix::Matrix::new(8, board);
    let display = MatrixDisplay::new(format, data);
    display.print(&mut std::io::stdout(), &style::BordersStyle::Thin);

TODO

• Leverage fdehau/tui-rs to avoid redrawing the entire screen at every frame
• Should help with performance issues with snake-rs, my snake implementations.
