PikeDevel/PikeFramework

Here's an example of using the framework to embed a Pike interpreter within your application:

#import <Pike/OCPikeInterpreter.h>
#import <Foundation/NSAutoreleasePool.h>
#import <Foundation/NSString.h>int main()
{
  id i;
  struct svalue * sv;
  // required for console mode objective c applications
  NSAutoreleasePool *innerPool = [[NSAutoreleasePool alloc] init];
  // these 3 lines set up and start the interpreter.
  i = [OCPikeInterpreter sharedInterpreter];
  [i setMaster: @"/usr/local/pike/7.7.30/lib/master.pike"];
  [i startInterpreter];
  // ok, now that we have things set up, let's use it.
  // first, an example of calling pike c level apis directly.
  f_version(0);
  printf("%s&#110;", Pike_sp[-1].u.string->str);
  pop_stack();
  // next, we'll demonstrate one of the convenience functions available
  sv = [i evalString: @"1+2"];
  printf("type: %d, value: %d&#110;", sv->type, sv->u.integer);
  free_svalue(sv);
  // finally, we clean up.
  [i stopInterpreter];
  [innerPool release];
  return 0;
}

The following commands can be used in conjunction with Pike.framework to generate a Bundle that when loaded, fires up a Pike interpreter. I plan on using this in conjunction with the Public.ObjectiveC module to produce bundles that load up like a standard Objective-C bundle, but in which all of the classes are written completely in Pike.

1. A Universal Build of Pike.framework would be nice 2. Bundling Public.ObjectiveC in Pike.framework 3. Extending the OC_Bundle.m template to add the bundle's Resource directory to the Pike program path, and fire up Public.ObjectiveC.

I expect #1 to be relatively simple to knock out: build Pike under PPC and Intel and then use lipo to build fat files for the Pike executable and any .so files.

Number 2 and 3 are probably another evening's worth of work, I'd guess. So, not a whole lot of work to be expended before we can do all kinds of crazy stuff with Pike!
