thought of are very fun or fast. This is the best I could come up with:
How about using a binary search? I don't know how fast this is for a lot of
tracks -- I don't have many in iTunes, myself...
----------
tell application "iTunes"
set testFile to location of file track 15 of playlist "Library"
set theList to location of every file track of playlist "Library"
if theList contains testFile then
set trackNum to binSearch(testFile, theList, 1) of me
return file track trackNum of playlist "Library"
end if
end tell
on binSearch(aTerm, aList, aNumber)
if (count of aList) = 1 then
return aNumber
else
set midItem to (((count of aList) / 2) as integer)
copy items 1 thru midItem of aList to tmp
if tmp contains aTerm then
binSearch(aTerm, tmp, aNumber)
else
binSearch(aTerm, items (midItem + 1) thru -1 of aList, <line-break>
aNumber + midItem)
end if
end if
end binSearch
----------
What's the speed like for you people with monster playlists?
