@@ -1,3 +1,35 @@ +//! This crate is a wrapper around [`std::process::Command`] or +//! [`async_process::Command`] which provides the ability to allocate a pty +//! and spawn new processes attached to that pty, with the pty as their +//! controlling terminal. This allows for manipulation of interactive +//! programs. +//! +//! The basic functionality looks like this: +//! +//! ```no_run +//! let mut pty = pty_process::Pty::new().unwrap(); +//! pty.resize(pty_process::Size::new(24, 80)).unwrap(); +//! let mut cmd = pty_process::Command::new("nethack"); +//! let child = cmd.spawn(&pty).unwrap(); +//! ``` +//! +//! The returned `child` is a normal instance of [`async_process::Child`] (or +//! [`std::process::Child`] for the [`blocking`](crate::blocking) variant), +//! with its `stdin`/`stdout`/`stderr` file descriptors pointing at the given +//! pty. The `pty` instance implements [`std::io::Read`] and +//! [`std::io::Write`] (or [`futures_io::AsyncRead`] and +//! [`futures_io::AsyncWrite`] for the [`blocking`] variant), and can be used +//! to communicate with the child process. The child process will also be made +//! a session leader of a new session, and the controlling terminal of that +//! session will be set to the given pty. +//! +//! # Features +//! +//! By default, only the [`blocking`](crate::blocking) APIs are available. To +//! include the asynchronous APIs, you must enable the `async` feature. See +//! the `examples` directory in the repository for examples of how to use this +//! crate with the various different asynchronous frameworks. + #![warn(clippy::cargo)] #![warn(clippy::pedantic)] #![warn(clippy::nursery)] |
