# ricenp, one np script to rule them all -- version 1.2
# created by Hunter <hunterm.haxxr@gmail.com> 2010-2012
#
# Continue down for configuration. Arguments are below too.
#
# Current version:
# 4-17-2015 -- fixed nuvolaplayer and clementine dbus queries, others are probably broken
#              added explanation for compact2 
#              added new format and explanation: compact3 which spits out simple "$artist - $title"
# 7-29-2012 -- let's start numbering our versions. this is version 1.1.
#              multiple formats! listing is below arguments.
#              writes errors to stderr like it should now
#              notify-send is no longer needed
# 7-25-2012 -- fixed totem support... again
#              changed name to ricenp because this script is extremely riced
# 7-23-2012 -- added support for xfce4-genmon-plugin
#              added support for choosing a player manually
#              added lastfm user querying from arguments
#              added play/pause toggling for most players
#                    ...not yet supported for vlc, decibel, or pogo
#              using getopt for argument reading now
#              fixed some players that had broken now playing parsing
#
# Arguments:
#   -p <player>  -- provide a player from the $apps variable and we will try to
#                   query that player instead of a player we've detected
#   -l           -- uses lastfm for showing now playing instead of a local player
#   -u <user>    -- uses <user> instead instead of the lastfm_user specified
#                   in the configuration variable $lastfm_user
#   -x           -- adjusts output format for use with xfce4-genmon-plugin
#   -t           -- toggle playing status of detected or specified player
#   -f <format>  -- uses format instead of format currently in configuration
#   -o           -- list valid formats
#   -h           -- show this help message
#
# Formats:
#   Explanation:
#       I would make the formats customizable by syntax and variables, but once you
#       get into that much customizability and you want mpc-style syntax is becomes
#       very complicated to do. Espically in shell script. But, it might be put in
#       some time. Until then, here's the formats that are available.
#   
#   Normal:
#       np: artist - title (On album/stream <album/stream title>)
#   Compact:
#       np: artist - title [album]
#   Compact2:
#       np: $artist ($album) - $title
#   Compact3:
#       $artist - $title
#   Full:
#       now playing: artist - title (On album/stream <album/stream title>)
#   Wordy1:
#       Now Playing: title by artist on <album/stream title>       
#   Wordy2:
#       Now Playing: title by artist [<album/stream title>]
#   Wordy3:
#       np: title by artist on <album/stream title>       
#   Wordy4:
#       np: title by artist [<album/stream title>]
#
# Changelog:
# 7-04-2012 -- added support for pretty much any player anyone uses
#              TODO: support for mplayer (if possible) and dragon player?
#
# 6-21-2012 -- added lastfm support
#              added clementine support (on request of iSpawn)
#
# 6-20-2012 -- fixed some weird bug with mpc
# 6-17-2012 -- updated banshee support
# 2-22-2012 -- added mpd password support
# 2-10-2012 -- added mocp support
# 2-04-2012 -- added spotify support



## Configuration Variables
MPD_HOST="localhost" # <password>@<host> or just <host>, nothing = localhost with no password
MPD_PORT= # uses normal port if empty
lastfm_user="whoever" # uses this name if you don't provide one to -l
format="compact3"

# xfce4-genmon related
use_genmon_img=true # if you'd like to show an image in addition to the np stuff
genmon_img="/usr/share/icons/gnome-colors-common/22x22/apps/gmusicbrowser.png"
use_genmon_click=true # if you want to be able to click on the image and execute
                      # the player toggle command

# You may adjust priority in which apps will be checked here.
# You can take out an app if you're sure you won't ever use it.
# Capitalization doesn't matter.
