vt100

This crate parses a terminal byte stream and provides an in-memory representation of the rendered contents.

Overview

This is essentially the terminal parser component of a graphical terminal emulator pulled out into a separate crate. Although you can use this crate to build a graphical terminal emulator, it also contains functionality necessary for implementing terminal applications that want to run other terminal applications - programs like screen or tmux for example.

Synopsis

let mut parser = vt100::Parser::new(24, 80, 0);

let screen = parser.screen().clone();
parser.process(b"this text is \x1b[31mRED\x1b[m");
assert_eq!(
    parser.screen().cell(0, 13).unwrap().fgcolor(),
    vt100::Color::Idx(1),
);

let screen = parser.screen().clone();
parser.process(b"\x1b[3D\x1b[32mGREEN");
assert_eq!(
    parser.screen().contents_formatted(),
    &b"\x1b[?25h\x1b[m\x1b[H\x1b[Jthis text is \x1b[32mGREEN"[..],
);
assert_eq!(
    parser.screen().contents_diff(&screen),
    &b"\x1b[1;14H\x1b[32mGREEN"[..],
);
