# 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

  Module](http://www.tornadoweb.org/en/stable/guide/templates.html#ui-modules).

JS:

- `terminado/_static/terminado.js`: A lightweight wrapper to set up a

  term.js terminal with a websocket.

Local Installation:

> $ pip install -e .\[test\]

Usage example:

```python

import os.path

import tornado.web

import tornado.ioloop

# This demo requires tornado_xstatic and XStatic-term.js

import tornado_xstatic

import terminado

STATIC_DIR = os.path.join(os.path.dirname(terminado.__file__), "_static")

class TerminalPageHandler(tornado.web.RequestHandler):

    def get(self):

        return self.render(

            "termpage.html",

            static=self.static_url,

            xstatic=self.application.settings["xstatic_url"],

            ws_url_path="/websocket",

        )

if __name__ == "__main__":

    term_manager = terminado.SingleTermManager(shell_command=["bash"])

    handlers = [

        (r"/websocket", terminado.TermSocket, {"term_manager": term_manager}),

        (r"/", TerminalPageHandler),

        (

            r"/xstatic/(.*)",

            tornado_xstatic.XStaticFileHandler,

            {"allowed_modules": ["termjs"]},

        ),

    ]

    app = tornado.web.Application(

        handlers,

        static_path=STATIC_DIR,

        xstatic_url=tornado_xstatic.url_maker("/xstatic/"),

    )

    # Serve at http://localhost:8765/ N.B. Leaving out 'localhost' here will

    # work, but it will listen on the public network interface as well.

    # Given what terminado does, that would be rather a security hole.

    app.listen(8765, "localhost")

    try:

        tornado.ioloop.IOLoop.instance().start()

    finally:

        term_manager.shutdown()

```
