iTunes and Windows and Perl == Bliss

Brethern --

I have been waiting for quite some time for an API into iTunes so that I could control it from my keyboard or X10 remote controls and they released an SDK awhile back that I just discovered.

I know that you Mac users have Mac::iTunes but Windows users can now control iTunes natively.

James Craig has done some excellent work with the SDK and I borrowed the "SearchiTunesWinForSong" routine from him.

I am going to come up with a more complete library of functions as time allows but wanted to get this out so folks know that they can start hacking away at iTunes.

Enjoy,
mdog

use Win32::OLE; Win32::OLE->Option(Warn => \&OLEError); #find and start a playlist my $playlistHandle = GetPlaylistFromSource("Matt","Library"); $playlistHandle->PlayFirstTrack(); # find and rate a song my $trackHandle = SearchiTunesWinForSong( artist => "10,000 Maniacs", title => "Candy Everybody Wants", location => "F:\\backup1\\mp3\\10,000 Mani +acs - Candy Everybody Wants.mp3" ); #various methods and objects are case insenstive my $status = $trackHandle->{RATing} = 80; print $trackHandle->{rAting} . "\n"; print $trackHandle->Rating . "\n"; # get the current song playing print GetCurrentlyPlayingSong() . "\n"; sub OLEError { print (Win32::OLE->LastError() . "\n"); } # you can this more directly if you reference the source and playlist +directly # but I prefer to have case insensitivity and partial source / playlis +t naming available sub GetPlaylistFromSource{ my($desiredPlaylist,$desiredSource) = @_; my ($iTunes) = new Win32::OLE( "iTunes.Application"); my $sources = $iTunes->Sources; my $count = $sources->{"Count"}; my $foundPlaylist; # loop through all the sources: be it library, radio, ipod, etc for(my $i = 1; $i <= $count; $i++){ my $source = $sources->Item($i); my $sourceName = $source->{"name"}; # found the source if($sourceName =~ /$desiredSource/i){ #print "$sourceName\n"; my $playlists = $source->Playlists; my $playlistCount = $playlists->Count; # now loop through all the playlist on that device / drive for(my $i = 1; $i <= $playlistCount; $i++){ my $playlist = $playlists->Item($i); my $playlistName = $playlist->{"name"}; if($playlistName =~ /$desiredPlaylist/i){ #print "\t$playlistName\n"; $foundPlaylist = 1; return $playlist; } } } } if(! $foundPlaylist){ print "Did not find desired playlist\n"; exit; } } sub GetCurrentlyPlayingSong{ my ($iTunes) = new Win32::OLE( "iTunes.Application"); # find out what the current track playing is my $currentTrack = $iTunes->CurrentTrack; my $location = $currentTrack->Location; my $filename = $location; $filename =~ s/^.*\\//gis; return $filename; } sub SearchiTunesWinForSong{ my %searchTerms=@_; my $IITrackKindFile = 1; my $ITPlaylistSearchFieldVisible = 1; my $status; my ($iTunes) = new Win32::OLE( "iTunes.Application"); # don't bother unless we have a location and at least one of title +/artist/album return 0 unless $searchTerms{location} and ($searchTerms{title} or + $searchTerms{artist} or $searchTerms{album}); # reverse the slashes in case SlimServer is running on UNIX #$searchTerms{location} =~ s/\//\\/g; #replace \\ with \ - not consistent within iTunes (not in my libra +ry at least) #$searchTerms{location} =~ s/\\\\/\\/; my $mainLibrary = $iTunes->LibraryPlaylist; my $tracks = $mainLibrary->Tracks; #now find it my $searchString = ""; if ($searchTerms{artist}) { $searchString .= "$searchTerms{artist} "; } if ($searchTerms{album}) { $searchString .= "$searchTerms{album} "; } if ($searchTerms{title}) { $searchString .= "$searchTerms{title}"; } #print( "Searching iTunes for *$searchString*\n"); my $trackCollection = $mainLibrary->Search($searchString, $ITPlaylistSearchFieldVisible); if ($trackCollection) { #print("Found ",$trackCollection->Count," track(s) in iTunes\n +"); #print("Checking for: *$searchTerms{location}*\n"); for (my $j = 1; $j <= $trackCollection->Count ; $j++) { #change double \\ to \ my $iTunesLoc = $trackCollection->Item($j)->Location; $iTunesLoc =~ s/\\\\/\\/; #watch out for blank space in iTunes (where did these come + from?) my $iTunesName = $trackCollection->Item($j)->Name; $iTunesName =~ s/\s*$//; my $iTunesArtist = $trackCollection->Item($j)->Artist; $iTunesArtist =~ s/\s*$//; my $iTunesAlbum = $trackCollection->Item($j)->Album; $iTunesAlbum =~ s/\s*$//; # escape all problem characters for search coming up my $searchLocation = $searchTerms{location}; $searchLocation =~ s/(\W)/\\$1/g; #check the name, location and type if ($trackCollection->Item($j)->Kind == $IITrackKindFile and (!$searchTerms{title} or $searchTerms{title} eq +$iTunesName) and (!$searchTerms{album} or $searchTerms{album} eq +$iTunesAlbum) and (!$searchTerms{artist} or $searchTerms{artist} eq +$iTunesArtist) #and ($searchTerms{location} eq $iTunesLoc) and ($iTunesLoc =~ m|$searchLocation$|) ) { #we have the file (hopefully) #print("Found track in iTunes\n"); return $trackCollection->Item($j); } else { #print("$j - False match: *$iTunesLoc*\n"); } } } return 0; }

    Okay, I'll be a little snarky and point out the following conjecture.
    iTunes + Windows + Perl == Bliss Ignorance == Bliss Windows == Ignorance .: Perl == -iTunes

    This looks pretty fun; I'll have to give it a spin when I get home. (kind of a lame comment, but I'm too new to be able to vote you up)

    I am a Perl programmer (obviously) and I love iTunes, but having Windows as part of something blissful seems to require such a lapse of the laws of physics that I must assume you are on drugs or Jayson Blair.

    Now Mac::iTunes, OTOH, is certainly enough to cause bliss, like watching Bill Gates get a blue screen of death.

      Damn, I am taking a lot of heat for the title of my posting.

      OK, I am not a Windows lover (rather a user) and the reason for my bliss is not because I am on Windows but because I can talk natively to iTunes via Perl.

      So the title of my post probably should have been "iTunes (on Windows) and Perl == Bliss". I was just so blissed / blitzed out that I did't realize my folly. Forgive me, monks, I will strive to do better.

      I won't change it so that folks reading this thread aren't confused.

      Time to self flaggelate!
