I've created the following AppleScript for deleting all the selected tracks:
property okflag : false
-- check if iTunes is running
tell application "Finder"
if (get name of every process) contains "iTunes" then set okflag to true
end tell
if okflag then
tell application "iTunes"
if selection is not {} then
repeat with this_track in selection
try
try
set cla to class of this_track
set floc to (get location of this_track)
delete this_track
on error error_message number error_number
display alert error_message message ("Error number: ") & error_number & "."
end try
if cla is file track then
my delete_the_file(floc)
end if
end try
end repeat
end if
end tell
end if
to delete_the_file(floc)
try
-- tell application "Finder" to delete floc
do shell script "mv " & quoted form of POSIX path of (floc as string) & " " & quoted form of POSIX path of (path to trash as string)
on error
display dialog "Track deleted, but could not be moved to trash" buttons {"Hmm"} default button 1 with icon 1
end try
end delete_the_file
It works fine when I select a single item, but when I select more than one I get: "Can't get location of item 2 of selection" (error number -1728). I believe this is because by deleting a track, the script's index into the selection is corrupted.
I thought I'd try making my own list of tracks to be deleted first:
tell application "iTunes"
if selection is not {} then
set to_delete to {}
repeat with this_track in selection
try
set cla to class of this_track
set floc to (get location of this_track)
if cla is file track then
set pair to {this_track, floc}
set to_delete to to_delete & pair
end if
end try
end repeat
repeat with pair in to_delete
set the_track to item 1 of pair
set floc to item 2 of pair
delete the_track
my delete_the_file(floc)
end repeat
end if
end tell
But then I get 'Can't get item 1 of item 1 of selection of application "iTunes".' I think the problem is "this_track" is not an object of class Track, but an item of a selection. How do I get the actual track object from the selection item?
If you don't see the solution, I'll welcome tips on debugging or any other suggestions.
The variable this_track
is a reference to an object specifier. You have to use the contents
property to get the enclosed object specifier. The same is true for accessing the variable pair
in the second loop. See the class reference section on the class reference
in the AppleScript language guide.
Another problem exists in the way the list to_delete
is being built. The statement set to_delete to to_delete & pair
will not produce a list of pairs but a flat list. See the class reference section on the class list
in the AppleScript language guide.
Here's a version of your second script, where these bugs have been removed:
tell application "iTunes"
if selection is not {} then
set to_delete to {}
repeat with this_track in selection
try
set cla to class of this_track
set floc to (get location of this_track)
if cla is file track then
set pair to {contents of this_track, floc}
copy pair to end of to_delete
end if
end try
end repeat
repeat with pair in to_delete
set the_track to item 1 of contents of pair
set floc to item 2 of contents of pair
delete the_track
my delete_the_file(floc)
end repeat
end if
end tell
