Appendix D. Theme Tags
D.23. Conditional Tags
Tag
%?xx<true|false>
%?xx<alt1|alt2|
alt3|...|else>
%if(tag,
operator,
operand, [option
count])
%and(tag1, tag2,
..., tagN)
%or(tag1, tag2,
..., tagN)
Examples of the %if tag:
%?if(%pv, >=, 0)<Clipping possible|Volume OK> will display "Clipping possible"
if the volume is higher than or equal to 0 dB, "Volume OK" if it is lower.
%?if(%ia, =, %Ia)<same artist> – this artist and the next artist are the same.
Note: When performing a comparison against a string tag such as %ia, only = and !=
work, and the comparison is not case sensitive.
