ptyprocess

A library provides an interface for a PTY/TTY.

The library provides a sync and async IO operations for communication. To be able to use async you must provide a feature flag [async] and turn off default features default-features = false.

The library was developed as a backend for a https://github.com/zhiburt/expectrl. If you're interested in a high level operations may you'd better take a look at zhiburt/expectrl.

Usage

```rust use ptyprocess::PtyProcess; use std::process::Command; use std::io::{Read, Write};

fn main() { // spawn a cat process let mut process = PtyProcess::spawn(Command::new("cat")).expect("failed to spawn a process");

// write message to cat.
process.write_all(b"hello cat\n").expect("failed to write");

// read what cat produced.
let mut buf = vec![0; 128];
let size = process.read(&mut buf).expect("failed to read");
assert_eq!(&buf[..size], b"hello cat\r\n");

// stop process
let sucess = process.exit(true).expect("failed to exit");
assert_eq!(sucess, true);

} ```

## Async

```rust use ptyprocess::PtyProcess; use std::process::Command;

[tokio::main]

async fn main() { // spawns a cat process let mut process = PtyProcess::spawn(Command::new("cat")).expect("failed to spawn a process");

// sends line to cat
process.send_line("hello cat").await.expect("failed writing");

} ```
