# mpd-dynamic(1p)

a dynamic playlist for mpd

## NAME

mpd-dynamic - a dynamic playlist for mpd

## VERSION

version 2.004

## DESCRIPTION

This program implements a dynamic playlist for MPD, build on top of the Audio::MPD perl module.

MPD (music player daemon) is a cool music player, but it lacks a dynamic playlist. A dynamic playlist is a playlist that will change automatically over time. In particular, it will remove already played songs (keeping at most a given number of songs) and add new songs to the playlist so it never fall short of songs.

Note that since mpd is a daemon needing no gui to work, `"mpd-dynamic"` is also a daemon. That is, it will fork and do all its work from the background. This way, you can fire `"mpd"` and `"mpd-dynamic"` and forget completely about your music (especially since `"mpd-dynamic"` is a low-resource program): it will just be there! :-)

## USAGE

```
    mpd-dynamic [options]
```

## OPTIONS

### General behaviour

You can customize the usage of mpd-dynamic with the following options:

- \-o\[ld\] \<old\>

  Number of old tracks to keep in the backlog. Defaults to 10.

- \-n\[ew\] \<new\>

  Number of new tracks to keep in the to-be-played playlist. Defaults to 10.

- \-s\[leep\] \<sleep\>

  Time spent sleeping (in seconds) before checking if playlist should be updated. Default to 5 seconds.

- \-d\[ebug\]

  Run mpd-dynamic in debug mode. In particular, the program will not daemonize itself. Default to false.

- \-e\[ncoding\] \<encoding\>

  Print debug messages with this encoding. Since mpd-dynamic is meant to be a silent daemon, this option will not be used outside of debug mode. Default to `"utf-8"`.

- \--version

  - \--usage

  - \--help

  - \--man

  Print the usual program information

Note however that those flags are optional: since `"mpd-dynamic"` comes with some sane defaults, you can fire `"mpd-dynamic"` as is.

### Ratings

You can also take advantage of ratings if you want. With those options, songs need to have at least a given rating (or no rating yet) to be inserted: this way, you will only listen to your favorite songs!

Ratings can be created / updated with `"mpd-rate"`.

Note that if you supply a non-existant rating db-file, the rating mechanism will be ignored. The following options control the rating mechanism:

- \-r\[atings\] \<ratings\>

  The path of a db file with the ratings per song. The keys are the song path (relative to MPD root), and the value is an integer (the rating). Default to `"~/.mpd/ratings.db"`.

- \-m\[in\[imum\]\] \<min\>

  The minimum rating for a song to be inserted in the playlist. Default to 4.
