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

comp requires Python 3.5+ with ``curses`` module (only available on Unix-like
OSes such as GNU/Linux and the BSDs) and ``libmpv`` (available as ``libmpv1``
in Debian/Ubuntu, openSUSE; and as ``mpv`` in Arch Linux, Gentoo, macOS
Homebrew repository). It also depends on ``python-mpv`` and ``youtube-dl`` but 
the setup program will automatically install them if they are missing.

Using pip
^^^^^^^^^

Python 2 is still the default on most distributions so the command would be
``pip3 install comp``. You can use the ``--user`` flag to avoid system-wide
installation.

Using setup.py
^^^^^^^^^^^^^^

To install the latest version or test development branches, you'll need to do
it manually::

   git clone https://github.com/McSinyx/comp.git
   cd comp
   ./setup.py install

Note that ``setup.py`` uses ``setuptools`` which is a third-party module and
can be install using ``pip3``.

Configuration files
-------------------

If not specified by the ``--config``, (user-specific) configuration file is
``~/.config/mpv/settings.ini``. Default configurations
are listed below::

   [comp]
   # Initial playing mode, which can be one of these 8 modes: play-current,
   # play-all, play-selected, repeat-current, repeat-all, repeat-selected,
   # shuffle-all and shuffle-selected.
   play-mode = play-current

   [mpv]
   # Initial video channel. auto selects the default, no disables video.
   video = auto
   # Specify the video output backend to be used. See VIDEO OUTPUT DRIVERS in
   # mpv(1) man page for details and descriptions of available drivers.
   video-output =

   [youtube-dl]
   # Video format/quality to be passed to youtube-dl. See FORMAT SELECTION in
   # youtube-dl(1) man page for more details and descriptions.
   format = best


Bugs
----

Media durations are not extracted from online playlists as
``youtube-dl.YoutubeDL`` option ``extract_flat`` is set to ``'in_playlist'``.
This is rather a feature to save up bandwidth than a bug because a track's
duration is updated when it's played.
