fzmp [OPTIONS]
OPTIONS:
-a --artist
search artist then filter by album (or F3 when running)
-A --all
search all songs in the library (or F2 when running)
-g --genre
list genres (or F4 when running)
-p --playlist
search the current playlist (or F1 when running)
playlist view has the following keybinds:
> go to the next song in the playlist
< go to the previous song in the playlist
Ctrl-d delete the selected songs from the playlist
Ctrl-s save current playlist
Ctrl-p toggle play/pause
-P --playlists
list saved playlists (or F5 when running)
-h --help
print this help
CONFIGURATION:
A configuration file can be defined at $config_file
If a line begins with '#' it is treated as a comment and ignored
The configuration file reads the following options:
default_view
Must be 'artists' 'songs' 'playlist' or 'genres'
full_song_format
A format string to be passed directly to \`mpc format -f\` in
'playlist' and 'all' views. Defaults to:
[[[%artist% / ][[(%date%) ]%album% / ][[%track% - ][%title%]]]|%file%]
For colorized output try:
[[[\\e\\[32m%artist%\\e\\[0m / ][\\e\\[31m[(%date%) ]%album%\\e\\[0m / ][\\e\\[34m[%track% - ][%title%]\\e\\[0m]]|%file%]
playlist_view_key (default F1)
track_view_key (default F2)
artist_view_key (default F3)
genre_view_key (default F4)
allows customizing which keys fire the different views
findadd_key
adds all songs under the cursor by artist/genre/album
(default ctrl-space)
fzf_options
Command line options to be passed directly to fzf.
Changing this will override the default options:
--height='100%' +s -e -i --reverse --cycle
To use the jump feature of fzf you can try:
--bind=\`:jump --height='100%' +s -e -i --reverse --cycle
It also helps to have a bind for toggle-all:
--bind=ctrl-t:toggle-all --bind=\`:jump --height=100% +s -e -i --reverse --cycle
individual sessions can override with the environment variable FZMP_FZF_OPTIONS
fzmp will also inherit options from FZF_DEFAULT_OPTS
