Re: [MacRuby-devel] Implementing Undo In RaiseMan / MacRuby

2009-10-27 Thread John Shea

Steve,

I am not sure what stage you are at with your example, I originally did this
without using an array controller, and the undoing worked fine.

I just threw together a version with an array controller - and the
insertObject(person,
inEmployeesAtIndex:index) and remove methods are being called by the array
controller - however they seem to be passing the index as a nil. Perhaps
this is what Ernest was talking about - an unboxing issue??
Undoing initially works.

Selecting the second row, and then pressing insert causes a crash into the
debugger - so perhaps again some issue with what method the array controller
is calling or trying to call  (and the vars it is trying to pass)  - as
Ernest implied (?).

Note that this experiment was still with 0.4.
Perhaps it works ok in later versions?

I personally have not come across this issue before because I never use the
arraycontroller method insert and remove - I always have my own controller
methods - usually I want to check other things before adding or removing (I
believe later in the book the array controller methods are replaced with own
methods).

Not a solution but perhaps you can work around it, by using your own
controller actions, and then exploring the undo aspects?

Cheers,
John

Re: [MacRuby-devel] Implementing Undo In RaiseMan / MacRuby

2009-10-27 Thread Benjamin Stiglitz


  def insertObject(p, inEmployeesAtIndex:index)
NSLog("adding #{p} to #{employees}") # <= Not called, huh?
undo = @undoManager
undo.prepareWithInvocationTarget(self,  
removeObjectFromEmployeesAtIndex:index)

if !undo.isUndoing
  undo.setActionName("Insert Person")
end
employees.insertObject(p, atIndex:index)
  end


FWIW, the third line of the body should read
undo.prepareWithInvocationTarget(self).removeObjectFromEmployeesAtIndex 
(index)

 Any update on this? I notice that the MacRuby 0.5 beta (nightly) simply

Comment:

 As of r2905, the new Embed MacRuby target makes a fresh new MacRuby .app
 49MB, and when passing --no-stdlib to macruby_deploy inside the target
 script the .app becomes 28MB.

 We will make further improvements in the near future to reduce the size of
 embedded macruby apps, but I think this bug can be closed.

 #fork will be hard to support in MacRuby because the underlying system

 I can appreciate that, but I really want to run something in a separate

 You can still spawn a new process (using #system, #`, #popen, etc.). If
 you want to run Ruby code in that process, you can spawn a new
 `/usr/bin/env macruby' process that way.

[MacRuby-devel] spotlight - MDItemRef

2009-10-27 Thread Alan Skipp

Would anyone be able to give me a hint on how to get the following
objective-c code working with macruby. The code uses spotlight to
extract metadata from a file.

MDItemRef inspectedRef =
MDItemCreate(kCFAllocatorDefault,(CFStringRef)path);
CFArrayRef attributeNames = MDItemCopyAttributeNames(inspectedRef);

NSLog(@"%@", (NSArray*)attributeNames);


I was hoping that including the 'CoreServices' framework would work, but
no joy.

2009-10-27 Thread Laurent Sansonetti


Hi Alan,

I'm afraid the MD* APIs haven't been covered by BridgeSupport yet, so  
it may not be possible to call it directly from MacRuby at this point.  
I would recommend to file a bug at http://bugreporter.apple.com so  
that we can consider this for a future Mac OS X release, and to wrap  
this C API into an Objective-C class that you can call from MacRuby in  
the meantime.
