WinPTY-rs
Overview
Create and spawn processes inside a pseudoterminal in Windows.
This crate provides an abstraction over different backend implementations to spawn PTY processes in Windows.
Right now this library supports using WinPTY
and ConPTY
.
The abstraction is represented through the [PTY
] struct, which declares methods to initialize, spawn, read,
write and get diverse information about the state of a process that is running inside a pseudoterminal.
Installation
In order to use Rust in your library/program, you need to add winpty-rs
to your Cargo.toml
:
[dependencies]
winpty-rs = "0.4"
In order to enable winpty compatibility, you will need the winpty redistributable binaries available in your PATH and LIB. You can download them from the official winpty repository releases, or using any known package manager in Windows.
Usage
This library offers two modes of operation, one that selects the PTY backend automatically and other that picks an specific backend that the user prefers.
Creating a PTY setting the backend automatically
use std::ffi::OsString;
use winptyrs::{PTY, PTYArgs, MouseMode, AgentConfig};
let cmd = OsString::from("c:\\windows\\system32\\cmd.exe");
let pty_args = PTYArgs {
cols: 80,
rows: 25,
mouse_mode: MouseMode::WINPTY_MOUSE_MODE_NONE,
timeout: 10000,
agent_config: AgentConfig::WINPTY_FLAG_COLOR_ESCAPES
};
// Initialize a pseudoterminal.
let mut pty = PTY::new(&pty_args).unwrap();
Creating a pseudoterminal using a specific backend.
use std::ffi::OsString;
use winptyrs::{PTY, PTYArgs, MouseMode, AgentConfig, PTYBackend};
let cmd = OsString::from("c:\\windows\\system32\\cmd.exe");
let pty_args = PTYArgs {
cols: 80,
rows: 25,
mouse_mode: MouseMode::WINPTY_MOUSE_MODE_NONE,
timeout: 10000,
agent_config: AgentConfig::WINPTY_FLAG_COLOR_ESCAPES
};
// Initialize a winpty and a conpty pseudoterminal.
let winpty = PTY::new_with_backend(&pty_args, PTYBackend::WinPTY).unwrap();
let conpty = PTY::new_with_backend(&pty_args, PTYBackend::ConPTY).unwrap();
General PTY operations
The PTY
provides a set of operations to spawn and communicating with a process inside the PTY,
as well to get information about its status.
// Spawn a process inside the pseudoterminal.
pty.spawn(cmd, None, None, None).unwrap();
// Read the spawned process standard output (non-blocking).
let output = pty.read(1000, false);
// Write to the spawned process standard input.
let to_write = OsString::from("echo \"some str\"\r\n");
let num_bytes = pty.write(to_write).unwrap();
// Change the PTY size.
pty.set_size(80, 45).unwrap();
// Know if the process running inside the PTY is alive.
let is_alive = pty.is_alive().unwrap();
// Get the process exit status (if the process has stopped).
let exit_status = pty.get_exitstatus().unwrap();
Examples
Please checkout the examples provided under the examples folder, we provide examples for both
ConPTY and WinPTY. In order to compile these examples, you can enable the conpty_example
and winpty_example
features when calling cargo build
