ParTTY

Pseudo terminals for Node.js, with smart defaults.

Overview

These are forkpty(3) bindings for Node.js, which allows you to fork processes with pseudo terminal file descriptors. It returns a terminal object which allows for reading and writing.

This is useful for:

  • Writing a terminal emulator.
  • Getting certain programs to think you're a terminal. This is useful if you need a program to send you control sequences.

Example Usages

Leveraging Smart Defaults

var ParTTY = require('partty');

// To leverage the smart defaults for sizing based on `process.stdout`,
// set the option `snap` to `true`:
var term = ParTTY.spawn('bash', [], { snap: true });

console.log('Launched ' + term.process + ' with PID ' + term.pid);

term.write('ls\r');
term.resize(100, 40);
term.write('ls /\r');

Exerting Manual Control

var ParTTY = require('partty');

var term =
  ParTTY.spawn(
    'bash',
    [],
    {
      name: 'xterm-color',
      cols: 80,
      rows: 30,
      cwd:  process.env.HOME,
      env:  process.env
    }
  );

term.on('data', function(data) {
  process.stdout.write(data);
});

console.log('Launched ' + term.process + ' with PID ' + term.pid);

term.write('ls\r');
term.resize(100, 40);
term.write('ls /\r');

TODO

  • Add tcsetattr(3), tcgetattr(3).
  • Add a way of determining the current foreground job for platforms other than Linux and OSX/Darwin.
