NAME

draai — manage playlists and play audio files

SYNOPSIS

draai [option [option ...]] command [track [track ...] | tracknumber [tracknumber ...]]

DESCRIPTION

Draai is a wrapper around mpc, making playing music from the commandline more enjoyable. mpc is a client for MPD, the Music Player Daemon. Using draai, one can play an audiofile (ogg, mp3, flac, whatever your MPD offers), play all files in a predefined playlist, view details on current, past and future playing songs, skip to the next song, etc.

GETTING STARTED

Run "draai init" to get started using draai the way the author likes it. Then, open another terminal window and run e.g. $ draai listall | dr_permutate | draai add; draai play to build a current playlist and start playing it. Other ways of using draai are possible, see below.

COMMANDS

draai

Play music: the files given as args and playlists passed via --playlist.

watch

Run watch(1) on "draai peek".

init

Start a bunch of X terminals setting up some draai jobs: tail, logtail, watch, syslog, ...

guestlist

Reschedule listed tracknumbers as upcoming tracks. Last arguments should be the positions of tracks to be put on the guestlist, not filenames.

unguestlist

Reschedule listed tracknumbers to end of playlist.

insert

Add file(s) (given either as args or on stdin) to playlist and schedule it as upcoming track. You probably want to have 'draai insert' read from a pipe fed by 'draai search'.

move

Move tracknumber to tracknumber given as last argument.

zap

Move tracknumber to position one and immediately start playing it. Typically used to deal with radiostations in playlist.

search

Search for substrings in all song tag types (artist, title, comment, filename, ...). Similar to 'mpc search any <query>'. You'll typically want to pipe this commands output to e.g. 'draai insert'.

tail

Print information about track when it starts playing, similar to tail -f on a logfile.

logtail

Run tail(1) on system log file.

list

List current playlist.

peek

Show status of current song, and show upcoming $peek FIXME tracks.

play

Play music.

syslog

Send raw information from tail to syslog. You likely want to run "draai syslog" in the background.

skip

Skip this track, start playing the next one now.

osjittisstil

Run this if unwanted silence pops up during a playing session (for now, it runs draai --sloppy skip).

delete

Delete track(s) from current playlist. Last arguments should be _positions_ of tracks to be removed, not filename. If no position is given, deletes upcoming track from playlist.

fastforward

Seek forward in current track.

crescendo

Play louder.

diminuendo

Play softer.

shuffle

Shuffle the playlist. By default, this task is delegated to dr_unsort(1). However, if draai runs in "sloppy" or in "native shuffle" mode, then mpc native shuffling is done (by calling "mpc shuffle"). Draai runs in "sloppy" mode when the DR_SLOPPY environment variable is set, or when the --sloppy option is passed. Draai runs in "native shuffle" mode when the DR_SHUFFLE_NATIVE environment variable is set.

listall

List all files as served by music database.

add

Add file(s) (given either as args or on stdin) to playlist. You probably want to have 'draai add' read from a pipe fed by e.g. 'draai listall' or 'draai search'.

quit

quit

OPTIONS

--debug (debug), -d

Be very verbose.

--playlist (with playlistfile), -p

Playlist file; option can be supplied more than once. To be used with command "draai".

--noshuffle (no shuffle), {-S}

Do not shuffle tracks and leave random mode untouched (default is: do shuffle and disable random mode). See also the script dr_unsort.

--raw (raw), -r

Print raw stuff, suitable for postprocessing (if combined with tail, peek or list).

--sloppy (sloppy), -s

Do not try hard to make everything sound smooth. If combined with skip: risk a squeak on old hardware.

--time (with timespec), -t

If combined with commands quit or draai: time at which to quit or start.

EXAMPLES

Schedule all tracks containing the string 'delia gone' in title, artist, comment or any other tag for playing, after current song has finished: draai search 'delia gone' | draai insert.

ENVIRONMENT

Run grep DR_ `which draai` to find out about environment variables honored by draai. It honors: booleans: DR_DEBUG, DR_SHUFFLE, DR_SHUFFLE_NATIVE, DR_TIMESTAMP, DR_RAW, DR_SLOPPY, DR_INIT_NCMPCPP and DR_INIT_WATCH ; strings: DR_WATCH ; integers: DR_CROSSFADE, DR_PEEK and DR_SEEK as well as DR_FADEOUT_STEP, DR_FADEOUT_REPEAT, and DR_FADEOUT_SLEEP and DR_VOLUME_STEP ; and some more strings: DR_SYSLOG_FILE, DR_SYSLOG_FACILITY and DR_SYSLOG_LEVEL . For now, see the draai code for what it all means.

FILES, CONFIGURATION

All configuration variables (see ENVIRONMENT) can be set in ~/.draai/rc. This rc-file is sourced as a shell script. If you'd like to set the syslog facility, set syslog_facility (overruled by DR_SYSLOG_FACILITY). If you'd like to set the watch programma, set watch (overruled by DR_WATCH).
