4.1.0

🚀 Features

📦 API

• A callback can now be specified when calling Terminal.write that fires when the terminal has parsed the provided data (#2422) via @jerch. This is useful to know when the terminal state has definitely been updated after a write since writes are deferred and done in chunks to avoid locking up the web page.

  const term = new Terminal();
  term.write('hello world', () => console.log('processed'));

  We decided to use a callback-based approach here rather than promise-based since write is one of the most performance critical parts of xterm.js and it can easily be adapted into a promise:

  const p = new Promise(r => term.write('hello world', r));

• Terminal.write and Terminal.writeln now accept an Uint8Array in addition to string (#2422) via @jerch
