Custom WPS Display
File Format Specifications
Description / General Info
--------------------------
* The Custom WPS Display is used on both the Rockbox Player and Recorder,
as a means to customize the WPS to the user's likings.
* After editing the .wps file, "play" it to make it take effect.
* The file may be 2 lines long for the Player, and 10 lines for the Recorder.
* The line that has the time displayed on it MUST NOT be the line that
is scrolled, or the time will not be updated.
* All characters not preceded by % are displayed as typed.
File Location
-------------
Custom WPS files may be located anywhere on the drive. The only restriction is
that they must end in .wps. When you PLAY a .wps file, it'll be used for the
future WPS screens. If the "played" wps file is located in the /.rockbox
folder, it'll be remembered and used for subsequent restarts.
Tags
----
(Options marked (*) have been added after the last official release, and are
thus only available in daily builds.)
ID3 Info Tags:
%ia : ID3 Artist
%id : ID3 Album Name
%ig : ID3 Genre Name (*)
%in : ID3 Track Number
%it : ID3 Track Title
%iy : ID3 Year
%iv : ID3 Version (1.0, 1.1, 2.2, 2.3, 2.4 or empty if no id3 tag) (*)
Battery Info:
%bl : Show numeric battery level in percent (*)
%bt : Show estimated battery time left (*)
File Info Tags:
%fb : File Bitrate (in kbps)
%ff : File Frequency (in Hz)
%fm : File Name
%fn : File Name (without extension)
%fp : File Path
%fs : File Size (In Kilobytes)
%fv : "(vbr)" if variable bit rate or "" if constant bit rate
%d1 : First directory from end of file path.
%d2 : Second directory from end of file path.
%d3 : Third directory from end of file path.
Example for the the %dN commands: If the path is "/Rock/Kent/Isola/11 -
747.mp3", %d1 is "Isola", %d2 is "Kent"... You get the picture.
Playlist/Song Info Tags:
%pb : Progress Bar
Player: This will display a 1 character "cup" that empties as the
progresses.
Recorder: This will replace the entire line with a progress bar.
%pc : Current Time In Song
%pe : Total Number of Playlist Entries
%pm : Peak Meter (Recorder only)
The entire line is used as volume peak meter.
%pn : Playlist Name (Without path or extension)
%pp : Playlist Position
%pr : Remaining Time In Song
%ps : Shuffle. Shows 's' if shuffle mode is enabled.
%pt : Total Track Time
Conditional Tags (If/Else block):
%?xx<|> : Conditional: if the tag specified by "xx" has a value, the
text between the "<" and the "|" is displayed, else the text
between the "|" and the ">" is displayed.
The else part is optional, so the "|" does not have to be
specified if no else part is desired. The conditionals nest,
so the text in the if and else part can contain all %
commands, including conditionals.
Other Tags:
%% : Display a '%'
%< : Display a '<'
%| : Display a '|'
%> : Display a '>'
%s : Indicate that the line should scroll. Can occur anywhere in
a line (given that the text is displayed; see conditionals
above). You can specify up to 10 scrolling lines (*).
%s is ignored if combined with %pb, %pc or %pr on the same
line (the result wouldn't be good anyway).
Example File
------------
%s%?in<%in - >%?it<%it|%fn> %?ia<[%ia%?id<, %id>]>
%pb%pc/%pt
That is, "tracknum - title [artist, album]", where most fields are only
displayed if available. Could also be rendered as "filename" or
"tracknum - title [artist]".
Default
-------
If you haven't selected a .wps file in the .rockbox directory, you get the
hardcoded wps layout. The default WPS screen is for player:
%s%pp/%pe: %?ia<%ia - >%?it<%it|%fm>
%pc%pb%pt
and for recorder:
%s%fp
%it
%id
%ia
%fb kbit %fv
Time: %pc / %pt
%pb
%pm
