Help with changing WPS information (disc/track#)

[RobDarst]

I am an old-timer with extremely limited programming skills. I'd be extremely grateful if someone could save me a great deal of frustration by explaining how to accomplish the following modification to the WPS. I currently use Cabbie v3 as my theme, with a larger font than the default.

Before the song title, I would like to see the disc number and track number (as recorded in the tag), separated by a period (or dash) and then a space before the title, like so: 1.05 Song Title (where "Song Title" is track #5 on disc #1).

If there is no disc number in the tag, then this value could be either default to 1, or no number and period/dash would appear, whichever is easier.

Many thanks in advance for your help.

All the information you might need is here http://www.rockbox.org/wiki/CustomWPS , and what you want to do only requires a little time of reading and editing, no special skills at all plus, after reading that, you'd be prepared to do almost any change to themes in the future, or, why not, make your own.

But in short, first you would have to open the theme's .wps file with a text editor.

Before the song title

that means you'd have to find there where the %it tag is (it could appear in several lines)

I would like to see the disc number and track number (as recorded in the tag), separated by a period (or dash) and then a space before the title, like so: 1.05 Song Title (where "Song Title" is track #5 on disc #1).

Replace %it with something like

Code: [Select]

%ik.%in %it

(means disc number tag, period, track number tag, space, track title tag)

If there is no disc number in the tag, then this value could be either default to 1, or no number and period/dash would appear, whichever is easier.

To add this conditional, you'd have to replace the %ik tag for a conditional, so the instruction would be something like

Code: [Select]

%?ik<%ik|1>.%in %it

means disc number conditional (%?ik = is disc number tag present?) if yes, display disc number, if not, display 1
The rest is like in the first example.

That should work if your tracks have the necessary tags (if not, you'd have to set more conditionals for the desired tags). I hope it helps

Many thanks for the suggestions. I wasn't able to make the quick-and-easy substitution work--the WPS loses its "theme" as a result--but I have a better sense of the programming involved now, and plan to start building my own WPS from the ground up once I have some "free time."

Great!

I took a look a the actual theme's code (ipod video), and this should work: Replace

Code: [Select]

%s%al%?it<%it|%fn>

with

Code: [Select]

%s%al%?ik<%ik|1>.%in %?it<%it|%fn>

and

Code: [Select]

%s%ac%?it<%it|%fn>

with

Code: [Select]

%s%al%?ik<%ik|1>.%in %?it<%it|%fn>

If you want  it also on the next track info, replace

Code: [Select]

%s%al%?It<%It|%Fn>

with

%s%al%?Ik<%Ik|1>.%In %?It<%It|%Fn>

and

Code: [Select]

%s%ac%?It<%It|%Fn>

with

Code: [Select]

%s%al%?Ik<%Ik|1>.%In %?It<%It|%Fn>

Aaargh! So close, and yet so far. Here's what happens: The WPS turns black, all theme elements vanish. The track name appears as "01. Title," with no disc number (not even the default "1"). The ordering of the rest of the WPS is also different, though I didn't change any of the other code--for example, the R/L volume bars appear, though they don't in the cabbie WPS. Is some other setting perhaps working at cross purposes?

Can you post your current .wps file? I tested the changes I posted and they work...

I gave it one last try before replying, and presto! it works. I have no idea what I did wrong before (I deleted the ones that didn't work). All's well that ends well--Many thanks for your help!
