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

```rust 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"); asserteq!( parser.screen().contentsformatted(), &b"\x1b[?25h\x1b[m\x1b[H\x1b[Jthis text is \x1b[32mGREEN"[..], ); asserteq!( parser.screen().contentsdiff(&screen), &b"\x1b[1;14H\x1b[32mGREEN"[..], ); ```
