Writing a terminal emulator in Rust from scratch

Rust’s ownership model maps well to PTY masters and parser state machines. This post sketches the architecture for a GPU-rendered terminal emulator.

PTY setup

Allocate with libc or nix, then spawn the shell on the slave side.

Parser pipeline

Bytes flow: stdin → ANSI parser → grid → render. Keep parsing incremental for streaming.

fn main() {
    println!("hello terminal");
}
