# Terminado

[![Build Status](https://github.com/jupyter/terminado/actions/workflows/test.yml/badge.svg?query=branch%3Amain++)](https://github.com/jupyter/terminado/actions/workflows/test.yml/badge.svg?query=branch%3Amain++)
[![Documentation Status](https://readthedocs.org/projects/terminado/badge/?version=latest)](http://terminado.readthedocs.io/en/latest/?badge=latest)

This is a [Tornado](http://tornadoweb.org/) websocket backend for the
[Xterm.js](https://xtermjs.org/) Javascript terminal emulator library.

It evolved out of [pyxterm](https://github.com/mitotic/pyxterm), which
was part of [GraphTerm](https://github.com/mitotic/graphterm) (as
lineterm.py), v0.57.0 (2014-07-18), and ultimately derived from the
public-domain [Ajaxterm](http://antony.lesuisse.org/software/ajaxterm/)
code, v0.11 (2008-11-13) (also on Github as part of
[QWeb](https://github.com/antonylesuisse/qweb)).

Modules:

- `terminado.management`: controls launching virtual terminals,
  connecting them to Tornado's event loop, and closing them down.
- `terminado.websocket`: Provides a websocket handler for
  communicating with a terminal.
- `terminado.uimodule`: Provides a `Terminal` Tornado [UI...

## AI interpretation — verify before relying

Terminado provides a Tornado websocket backend that connects the Xterm.js browser terminal emulator to system shells, enabling interactive terminal sessions over the web.

Verdict: Terminado is a mature, permissively licensed websocket terminal backend suitable for Jupyter and other Tornado-based web applications. No known vulnerabilities, low install friction, and active maintenance within the Jupyter project make it a reliable choice for browser-based terminal access—though the 884-day gap since last release warrants checking for any pending fixes before production deployment.
