This is a Tornado websocket backend for the term.js Javascript terminal emulator library.

It evolved out of pyxterm, which was part of GraphTerm (as lineterm.py), v0.57.0 (2014-07-18), and ultimately derived from the public-domain Ajaxterm code, v0.11 (2008-11-13) (also on Github as part of 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.

JS:

• terminado/_static/terminado.js: A lightweight wrapper to set up a term.js terminal with a websocket.

Usage example:

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()
