mpdnoti

#!/bin/bash

# Formats a notification with mpd metadata (which should be the song metadata).
# Also, displays the image cover of the current song album: this image cover
# needs to have the same name as the album in the song, and the extension can
# be .png, .jpg or .jpeg. If no matches, uses $coverDir/sample.png as the image.

# Dep: mpd, mpc

# Where the image file covers are searched
coverDir="${HOME}/.local/share/covers"

# first argument, else this hardcoded value: how much time does the
# notification stays (in ms)
