[MacRuby] #723: nsset + bindings error
by MacRuby 25 May '10

#723: nsset + bindings error -----------------------------------+---------------------------------------- Reporter: jakub.suder@… | Owner: lsansonetti@… Type: defect | Status: new Priority: major | Milestone: Component: MacRuby | Keywords: -----------------------------------+---------------------------------------- I have a weird error related to NSSet.setWithObjects method and bindings. I'm not sure exactly what causes it, but my guess is that it's some kind of problem with methods that accept variable number of arguments, that only appears in some specific conditions. It took me a few hours to isolate only the relevant code, but I managed to cut it down to two small classes where changing anything else makes the error disappear (see attached zip with a project). So I have a model class with 3 fields and 2 helper methods using those fields. For those 2 helper methods, I provide KVO methods keyPathsForValuesAffecting*** returning sets. In the app delegate, I create one instance of that class and 2 views, and bind two properties of the views to the methods in the model object. When I get to NSSet.setWithObjects("sender", "recipient", nil) in keyPathsForValuesAffectingSenderAndRecipient, the application hangs. Now, if I change anything in this code, it stops hanging; for example: - if I use NSSet.setWithArray(["sender", "recipient"]), it works - if I use a set with just "sender" (NSSet.setWithObjects("sender", nil)), it works - if I delete the second KVO method (keyPathsForValuesAffectingHasPicture), the first one starts working - if I don't bind the first view to keyPathsForValuesAffectingHasPicture, or change the order of bindings, it starts working - if I return a 2-element set in keyPathsForValuesAffectingHasPicture, it starts working (?!) - and here's the funniest one: if I copy the line NSSet.setWithObjects("sender", "recipient", nil) to application delegate, before the bindings, it works there, and the original invocation inside keyPathsForValuesAffectingSenderAndRecipient also magically starts working (?!?!) As you can see, it's hard to figure out what's going on here... But as far as I can tell, this smells to me like some kind of bug related to memory, pointers pointing to wrong places and so on... (oh, good old C times... :) And BTW, if I rewrite the model class (Message) in ObjC, it also starts working. Tested on MacRuby 0.6. -- Ticket URL: <http://www.macruby.org/trac/ticket/723> MacRuby <http://macruby.org/>

DictionaryServices
by ecin 24 May '10

24 May '10

I'd like to use Dictionary Services (http://developer.apple.com/mac/library/documentation/UserExperience/Referen…) to look up definitions in a MacRuby app, but am having a hard time figuring out exactly what I need to require in order to access its functions, as framework 'Cocoa' framework 'CoreServices' doesn't do the trick. Is this another example of missing bridge support, or am I missing something else?

Embed does not seem to work anymore after upgrading from 0.5 to 0.6
by Jeroen Jacobs 24 May '10

24 May '10

I've recently upgraded from 0.5 to 0.6. When I checked if one of my apps still was okay I noticed a problem when embedding MacRuby into the application and running it on a MacRuby-less machine. The first time it's trying to require something from MacRuby (in this case Singleton and/or CGI) it throws a LoadError: *** Terminating app due to uncaught exception 'LoadError', reason: 'no such file to load -- singleton (LoadError)' The code can be found at GitHub: http://github.com/jeroenj/chill For some reason the problem does not resist with new projects. So my best guess is that there is something configured wrong in the project but I cannot seem to find out what.

NSView.knowsPageRange( range )
by Robert Rice 23 May '10

23 May '10

I'm have some trouble understanding the new Pointer class. In older versions of MacRuby I used: def knowsPageRange( range ) # Override pagination. Image my clip on some printers # The range is passed by reference. range.location = 1 # first page number range.length = 1 true end MacRuby 0.6 gives me undefined method location= for the Pointer class. Adding an index eliminates the error but then my printing doesn't stop at one page: def knowsPageRange( range ) # Override pagination. Image my clip on some printers # The range is passed by reference. range[0].location = 1 # first page number range[0].length = 1 true end How can I fix this? Thanks, Bob Rice
