[MacRuby-devel] Compilation Clarification

I tested that and it is looking great: only 1379704 bytes for my small app!

That size makes MacRuby really useable for Quicklook and Spotlight plugins. But what about garbage collection? 

If Macruby.sharedRuntime.evaluateString could use memory of an enclosing NSAutoreleasePool it would be very easy:


OSStatus GeneratePreviewForURL(void *thisInterface, QLPreviewRequestRef preview, 
    CFURLRef url, CFStringRef contentTypeUTI, CFDictionaryRef options)
{
  if (QLPreviewRequestIsCancelled(preview))
    return noErr;
  NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
  …;
  NSMutableString* html = [[MacRuby sharedRuntime] evaluateString ….];
  QLPreviewRequestSetDataRepresentation(preview,
         (CFDataRef)[html dataUsingEncoding:NSUTF8StringEncoding], 
         kUTTypeHTML, (CFDictionaryRef)props);
  [pool release];
  return noErr;
}
