This library makes it easy to communicate with the Google Chrome remote debugging shell from Python. To make the shell available, start Chrome with this option:

google-chrome --remote-shell-port=9222

Then you can connect from Python through code like this:

>>> import chrome_remote_shell
>>> shell = chrome_remote_shell.open(port=9222)
>>> shell.request('DevToolsService', command='ping')
{u'data': u'ok', u'command': u'ping', u'result': 0}

The protocol is described in detail at:

http://code.google.com/p/chromedevtools/wiki/ChromeDevToolsProtocol

As a convenience, the shell connection object offers a method that, by injecting JavaScript into the first tab, commands Chrome to open a URL in a new tab:

shell.open_url('http://www.aldaily.com/')
