Or is it impossible ?? (I realy hope its not)

Yes, they have. I saw it in the foo_infopanel thread awhile ago, but it has grown to many pages since.

this:

$puts(len,40)
$puts(title,$if2(%title%,%_filename_ext%))
$iflonger($get(title),$get(len),
$puts(diff,$sub($len($get(title)),$get(len)))
$puts(start,$add(1,$mod(%_time_elapsed_seconds%,$get(diff))))
$puts(start2,$select($add($div($add(1,$mod( %_time_elapsed_seconds%,$mul($get(diff),2))),$add($get(diff),1)),1),$get(start),$sub($add($get(diff),1),$get(start))))
$substr($get(title),$get(start2),$add($get(start2),$get(len)))
,$get(title))

should do the trick. len,40 is the desired length, here 40.

what if one should want to put in different information?
i had mine displaying this:
[%artist% - ]['['%album%[ CD%discnumber%][ #%tracknumber%]']']%title%  %playback_time_remaining%

before i tried this whole scrolling bit, i figured trying to put it into the second $puts line would get me where i was going, like this:
$puts(title,$if2(%artist%,%album%,%discnumber%,%tracknumber%,%title%,%playback_time_remaining%))

but that just keeps returning:
[INVALID $IF2 SYNTAX]

any ideas?

As the error indicates, you are not using $if2() properly.. you have way too many parameters.  Is this what you are trying to accomplish?
Code: [Select]
$puts(title,$if2([%artist% - ]['['%album%[ CD%discnumber%][ #%tracknumber%]']']%title% %playback_time_remaining%,%_filename_ext%))

A very simplified version:
Code: [Select]
$puts(window,22)
$puts(scrollback,1)
$puts(delay,6)
$puts(font,arial,9,,)
$puts(title,['"'%title%'"'][ - %artist%]['/'%album%] ['('%date%')'])

$get(active)
$if($greater($len($get(title)),$get(window)),
$puts(shift,$sub($len($get(title)),$get(window)))
$if($get(scrollback),
$puts(mod,$mod(%_time_elapsed_seconds%,$add($mul($get(shift),2),$sub($get(delay),1))))
$if($greater($get(delay),$get(mod)),$substr($get(title),1,$get(window)),
$puts(mod,$sub($get(mod),$sub($get(delay),1)))$puts(flag,$get(mod))
$if($greater($add($get(shift),1),$get(mod)),
$substr($get(title),$add(1,$get(mod)),$add($get(window),$get(mod))),
$substr($get(title),$sub($mul($get(shift),2),$get(mod),-1),
$add($get(window),$sub($mul($get(shift),2),$get(mod),0))))),
$puts(mod,$mod(%_time_elapsed_seconds%,$add($mul($get(shift),2),$sub($get(delay),1))))
$if($greater($get(delay),$get(mod)),$substr($get(title),1,$get(window)),
$puts(mod,$sub($get(mod),$sub($get(delay),1)))
$substr($get(title),$add(1,$get(mod)),$add($get(window),$get(mod))))),
$align(center,middle)
$get(title))

Just replace the "$get(active)" to your color definition and the "title"-to your text
