## Detailed Description

Classes to send a Command to lircd and parse the reply.

## Sending data

Sending commands is about creating a command and connection. In the simplest form it looks like

    import lirc
    with lirc.CommandConnection(socket_path=...) as conn:
        reply = lirc.StopRepeatCommand(conn, 'mceusb', 'KEY_1').run()
    if not reply.success:
        print(parser.data[0])

See also the list-remotes.py, list-keys.py and simulate.py examples.

The parameters depends on the actual command; there is a Command defined for all known lircd commands. socket_path can often be omitted, see get_default_socket_path() for default locations used.

The returned object is a Reply with various info on the processed command.

To get more control lower-level primitives could be used instead of run() as in this example:

    while not command.parser.is_completed():
        line = conn.readline(0.1)
        if line:
            command.parser.feed(line)
        else:
            ... handle timeout
    if not command.parser.result == lirc.client.Result.OK:
        print('Cannot get version string')
    else:
        print(command.parser.data[0])
    ...
    conn.close()
