此 crate 为与系统提供的伪终端 (pty) 接口进行交互提供了跨平台 API。与其他此空间中的 crate 不同，此 crate 提供了一组 trait，允许在运行时选择不同的实现。此 crate 是 wezterm 的一部分。

use portable_pty::{CommandBuilder, PtySize, native_pty_system, PtySystem};
use anyhow::Error;

// Use the native pty implementation for the system
let pty_system = native_pty_system();

// Create a new pty
let mut pair = pty_system.openpty(PtySize {
    rows: 24,
    cols: 80,
    // Not all systems support pixel_width, pixel_height,
    // but it is good practice to set it to something
    // that matches the size of the selected font.  That
    // is more complex than can be shown here in this
    // brief example though!
    pixel_width: 0,
    pixel_height: 0,
})?;

// Spawn a shell into the pty
let cmd = CommandBuilder::new("bash");
let child = pair.slave.spawn_command(cmd)?;

// Read and parse output from the pty with reader
let mut reader = pair.master.try_clone_reader()?;

// Send data to the pty by writing to the master
writeln!(pair.master.take_writer()?, "ls -l\r\n")?;
