Anyone know how to get the index of the current iTunes track using
Scripting Bridge? With Applescript, it's as simple as "tell iTunes
to return index of current track", but iTunes SB has no such
property (well, there is one, but it only refers to the index of the
current playlist). It seems the iTunesTrack index property is simply
missing...? Or am I missing something?
What's missing is the line in iTunes' dictionary that says that tracks
have an "index" property in the first place. Scripting Bridge takes
the dictionary at its word, and therefore, no -[iTunesTrack index]
accessor. Ultimately, it's an iTunes bug. In the meantime, you can
work around the problem by using the raw codes [1]:
int index = [[[[iTunes currentTrack] propertyWithCode:'pidx'] get]
intValue];
Ordinarily, Scripting Bridge would take care of the -get and -intValue
for you, since this is an attribute you're dealing with [2], but if
you're dropping down to the base level, you have to be explicit.

[1] You can find the raw code by inspecting the dictionary. For spot
queries like this, I find it easiest to use Terminal:
% sdef /Applications/iTunes.app | xmllint --format - | grep
'name="index"'
<property name="index" code="pidx" type="integer" access="r"
description="the index of the playlist in internal application order"/>
[2] This is covered in the documentation under "Lazy Evaluation":
when you use an accessor that returns an attribute (in other words,
anything that isn't an SBObject descendant or SBElementArray),
Scripting Bridge will automatically do a -get and unbox the value for
you.
