poezio/plugins/mpd_client.py

"""
This plugin is here to send what you are listening to in a chat tab.



Installation
------------

You need `python-mpd`_, in its python3 version.

Then you can load the plugin.

.. code-block:: none

 /load mpd_client


Configuration
-------------

You have to put the following into :file:`mpd_client.cfg`, as explained in
the :ref:`plugin-configuration` section.

.. note:: If you do not put anything, the plugin will try to connect to
        :file:`localhost:6600` with no password.

.. code-block:: ini

    [mpd_client]
    host = the_mpd_host
    port = 6600
    password = password if necessary


Usage
-----

.. glossary::

    /mpd
        **Usage:** ``/mpd [full]``

        The bare command will show the current song, artist, and album

        ``/mpd full`` will show the current song, artist, and album,
        plus a nice progress bar in color.

.. _python-mpd: https://github.com/Mic92/python-mpd2
