This provides utilities for in-memory emulation of ANSI-escaped terminal data and rendering emulated terminal screens to SVG files. Have a look at the documentation or see the Termsnap README.

lib.rs:

In-memory emulation of ANSI-escaped terminal data and rendering emulated terminal screens to SVG files.

use termsnap_lib::{FontMetrics, Term, VoidPtyWriter};

// Create a new terminal emulator and process some bytes.
let mut term = Term::new(24, 80, VoidPtyWriter);
for byte in b"a line of \x1B[32mcolored\x1B[0m terminal data" {
    term.process(*byte);
}

// Create a snapshot of the terminal screen grid.
let screen = term.current_screen();

let text: String = screen.cells().map(|c| c.c).collect();
assert_eq!(text.trim(), "a line of colored terminal data");

assert_eq!(&format!("{}", screen.get(0, 0).unwrap().fg), "#839496");
assert_eq!(&format!("{}", screen.get(0, 10).unwrap().fg), "#859900");

// Render the screen to SVG.
println!("{}", screen.to_svg(&[], FontMetrics::DEFAULT));
