Hi guys, I've adopted a pragmatical workaround that insanely works: ar = %x[mdfind -literal 'kMDItemDisplayName == *.pdf && kMDItemFSSize > 100000'].split("\n") p "found #{ar.count} pdf > 100.000 bytes" In this way I can do something like that: ar2d = ar.collect {|x| [Digest::MD5.hexdigest(File.read(x)), x]} that is, perform an operation for each file found and assign the result to the file path. I am fully satisfied now, although this does not directly use the CoreServices framework, my interest is in understanding more fully how to use MD* interfaces directly in the code MacRuby, so if someone managed to do it I'd love to hear news. greetings, Franco Rondini > > 1. > ---------------------------------------------------------------------- > > Message: 1 > Date: Tue, 1 Mar 2011 00:12:53 +0100 > From: Franco Rondini <rondinif(a)yahoo.it> > To: macruby-devel(a)lists.macosforge.org > Subject: Re: [MacRuby-devel] Trying to use spotlight programmatically > Message-ID: <3964BBA2-BB57-4860-B45B-39B3E1742351(a)yahoo.it> > Content-Type: text/plain; charset="us-ascii" > > Hello , > The code posted by Kaelin works great for me, > After counting the number of search results now I would like to know the path of files found but to do this I have big difficulty > > I'm trying to figure out how to make it works the MDQueryGetAttributeValueOfResultAtIndex or MDItemCopyAttribute to read out the KMDItemPath or KMDItemFSName but I was a bit confused by the "Pointer" returned and even I get a # Illegal instruction as you can see in the following code: > > framework "CoreServices" > #=> true > query = MDQueryCreate(KCFAllocatorDefault, "kMDItemDisplayName = '*.pdf'", [KMDItemFSName,KMDItemPath] , nil) > #=> #<__NSCFType:0x2005d63a0> > MDQueryExecute(query, KMDQuerySynchronous) > #=> true > # item = MDQueryGetResultAtIndex(query, 1); > #=> #<Pointer:0x20052dc80> > count = MDQueryGetResultCount(query) > p "found #{count} documents" #=> 981 > a = MDQueryGetAttributeValueOfResultAtIndex(query, KMDItemFSName, 2) > p a #<Pointer:0x20059aee0> ..not a NSString > p a[0] #0 > p a[1] #4 > > item_ref = MDQueryGetResultAtIndex(query, 1) > p item_ref #<Pointer:0x200582460> > p item_ref.class #Pointer ..not a MDItemRef > path = MDItemCopyAttribute( item_ref, KMDItemPath) #Illegal instruction > p path > > I've found an older post of 2009 titled: "[MacRuby-devel] spotlight - MDItemRef" where Laurent said: "I'm afraid the MD* APIs haven't been covered by BridgeSupport yet.." > but because of i can see the MDQueryGetResultCount working I hope that there is a way to enumerate the results of the query to get the attributes ( path especially ) > I would be very happy if anyone has any idea, > Thanks > Franco > >

Re: [MacRuby-devel] Focus window from second XIB

Turns out that it works if I hook the window outlet to File's Owner instead of the Preferences Controller delegate. (The amount of at first sight reasonnable ways to do things can be confusing at times.) Thanks for your hints! -sven

Forgot to mention that I've tried preferences.windows.center() already, however, preferences.window is nil and therefore the center method call kabooms. (If I check the "visible at launch", the window shows and window is still nil - eventhough the delegate appears to be hooked up okay.) By the way: I'm on MacRuby 0.9 and Xcode 4 GM.

Focus window from second XIB
by Sven Schwyn 01 Mar '11

Hi For the preferences, I've created a second XIB. However, when the corresponding controller is instantiated, the window does appear but does not gain focus. Any idea what I'm doing wrong here? preferences_controller.rb: class PreferencesController < NSWindowController def windowNibName() return "Preferences" end end application_controller.rb: def menu_preferences(sender) preferences = PreferencesController.new end The Preferences.xib has a delegate which points to PreferencesController which has it's window outlet point to the window. The File's Owner is also set to the PreferencesController. Thanks for your help! -sven
