That was clever. I didn't think I could possibly read the source code and find it, all these source code don't mean much to me.
But I found it !
Here is the content of the rockbox_failsafe WPS, ready to copy & paste in a .wps file:
%s%?it<%?in<%in. |>%it|%fn>
%s%?ia<%ia|%?d(2)<%d(2)|%(root%)>>
%s%?id<%id|%?d(1)<%d(1)|%(root%)>> %?iy<%(%iy%)|>
%al%pc/%pt%ar[%pp:%pe]
%fbkBit %?fv<avg|> %?iv<%(id3v%iv%)|%(no id3%)>
%pb
%pm
I was trying to make it from scratch, just with the appearance I saw and the simulator, that was my own one:
#activate the status bar (%wd to disable)
%we
#Track number. Track Title
%s%in. %it
#Artist
%s%ia
#Album
%s%id %(%iy%)
#File Path
%s%fp
%pc/%pt%ar[%pp:%pe]
#%pb(x,y,[width],[height],image.bmp)
%pb
#Peak Meter - full line
%pm
#Next song
%s Next: %It - %Ia
As you can see, my WPS was much more simple, yet a little tweaked, and less efficient because it could not handle any exception. Nevertheless, for a first try in creating a WPS file, it was interesting, and maybe one day I will make my own super-cool WPS and - why not ? - a whole theme.
Yeah, since it was for me the very first time I designed a theme file, I felt like I HAD TO comment every single line, hehe ^^
Thanks for helping me to find this piece of code =)
