"""Displays the current song being played in DeaDBeeF and provides
|
|
some media control bindings.
|
|
Left click toggles pause, scroll up skips the current song, scroll
|
|
down returns to the previous song.
|
|
|
|
Requires the following library:
|
|
* subprocess
|
|
Parameters:
|
|
* deadbeef.format: Format string (defaults to '{artist} - {title}')
|
|
Available values are: {artist}, {title}, {album}, {length},
|
|
{trackno}, {year}, {comment},
|
|
{copyright}, {time}
|
|
This is deprecated, but much simpler.
|
|
* deadbeef.tf_format: A foobar2000 title formatting-style format string.
|
|
These can be much more sophisticated than the standard
|
|
format strings. This is off by default, but specifying
|
|
any tf_format will enable it. If both deadbeef.format
|
|
and deadbeef.tf_format are specified, deadbeef.tf_format
|
|
takes priority.
|
|
* deadbeef.tf_format_if_stopped: Controls whether or not the tf_format format
|
|
string should be displayed even if no song is paused or
|
|
playing. This could be useful if you want to implement
|
|
your own stop strings with the built in logic. Any non-
|
|
null value will enable this (by default the module will
|
|
hide itself when the player is stopped).
|
|
* deadbeef.previous: Change binding for previous song (default is left click)
|
|
* deadbeef.next: Change binding for next song (default is right click)
|
|
* deadbeef.pause: Change binding for toggling pause (default is middle click)
|
|
Available options for deadbeef.previous, deadbeef.next and deadbeef.pause are:
|
|
LEFT_CLICK, RIGHT_CLICK, MIDDLE_CLICK, SCROLL_UP, SCROLL_DOWN
