Project Description

Listen for commands over a unix socket and execute them in the terminal.

It solves the problem of text editors not wanting to bundle a real terminal emulator.

delgado requires valid JSON objects to be fired over a predetermined UDS (Unix Domain Socket). Delgado has to know about what commands is authorized to execute before running them, preventing arbitrary commands to be run).

A very simple listener allowed to run ls only would look like this:

$ delgado run --allowed ls

On a different terminal, sending the JSON to that socket could be something like:

$ echo '{"ls": ["/tmp/foo"]}' | nc -U  /tmp/delgado.sock

The echo pipes over to nc (BSD Netcat) that in turn sends the information to the socket. With the default logging levels, the output would then look like this:

$ delgado run --allowed ls
--> Running command: [u'ls']


If you are planning on using netcat make sure it is the BSD version that has support for UDS (using the -U flag). The GNU version will not work. You can use any tool that can communicate over UDS.


delgado was built with some modularity in mind, by default you get the py.test plugin which will run the server and listen for py.test commands only.

The plugins use setuptools entry points. If you want a new plugin to be available, this is what it should have on its file:

    entry_points = dict(
        delgado_handlers = [
            'my_command = my_package.my_module:MyClass',

The MyClass should be a class that accepts sys.argv as its argument, delgado will pass that in at instantiation and call a parse_args method.

This is how the py.test plugin looks like for example:

class Pytest(object):

    help_menu = 'A handler for running py.test commands'
    _help = """
Run a base socket listener that allows py.test commands.

--socket-location   The location for the socket (defaults
                    to /tmp/pytest.sock)

    def __init__(self, argv):
        self.argv = argv

    def parse_args(self):
