[Haskell-cafe] HOC is dead! Long live HOC!

[Joel Reymont]

BridgeSupport [1] is new functionality in Leopard that makes the  
current Haskell Objective-C bindings (HOC) obsolete (almost).

---
The metadata is intended to be a resource for use beyond bridging.  
Most frameworks on the system provide two chunks of XML BridgeSupport  
metadata; succinct and full.

The succinct version contains all of the metadata not provided by the  
Objective-C runtime (which provides about 80% of what is necessary to  
do full fidelity calls in / out of Objective-C via libffi).

The full version contains just that, the full metadata required to  
describe the APIs of the framework, including all the bits that could  
be gleaned at runtime.
---

BridgeSupport makes it unnecessary to parse Cocoa headers since all  
the required data is right there in plain XML [2]. It's no longer  
necessary to bundle libffi with HOC either since Leopard comes with a  
much improved version.

I hereby propose to close up the old HOC project on SourceForge and  
set up a new one at GoogleCode. I already did this but GoogleCode  
noticed the SF project and is now waiting for permission from Wolfgang  
and Andre.

	Thanks, Joel
