Crate kou 

kou — Virtual terminal automation.

PTY management + a real VT100/ANSI screen emulator (via vte) + screen rendering that can rasterise to PNG with proper fonts or describe the frame to a capable terminal through a graphics protocol (kitty / iTerm2). Extracted from tairitsu’s vtty engine as a standalone library.

Quick Start

use kou::VttyManager;

let mgr = VttyManager::new();
let info = mgr.launch("bash", None, &[], 80, 24, None).await?;
mgr.send_text(&info.id, "echo hello\n").await?;
let screen = mgr.screenshot(&info.id).await?;
println!("{}", screen);
