GNUstep Objective-C Runtime 1.3
|
|
|
|
|
===============================
|
|
|
|
|
|
|
|
|
|
This is the fourth official release of the GNUstep Objective-C runtime (a.k.a.
|
|
|
|
|
libobjc2). This runtime was designed to support the features of Objective-C 2
|
|
|
|
|
for use with GNUstep and other Objective-C programs.
|
|
|
|
|
|
|
|
|
|
This release contains several bug fixes and includes a unified exception
|
|
|
|
|
model, providing the same features as Apple's Modern runtime for Objective-C++
|
|
|
|
|
code, specifically the ability to throw Objective-C objects with @throw() or
|
|
|
|
|
throw() and catch them with @catch() or catch(). The new unified exception
|
|
|
|
|
model is supported by Clang 2.9 and is compatible with Apple's Objective-C++
|

|
|
|
exception behaviour. Another enhancement in this release is the addition of
|
|
|
|
|
support for class aliases. This provides a run-time equivalent of
|
|
|
|
|
@compatibility_alias, allowing a class to show up in class lookup searching for
|
|
|
|
|
its alias.

The runtime library is responsible for implementing the core features of the
|
|
|
|
|
object model, as well as exposing introspection features to the user. The
|
|
|
|
|
GNUstep runtime implements Apple's Objective-C Runtime APIs, and a small number
|
|
|
|
|
of GCC APIs for legacy compatibility.
|
|
|
|
|
|
|
|
|
|
This library is based on the Étoilé Objective-C Runtime, an earlier research
|
|
|
|
|
prototype, and includes support for non-fragile instance variables,
|
|
|
|
|
type-dependent dispatch, and object planes. It is fully compatible with the
|
|
|
|
|
FSF's GCC Objective-C ABI and also implements a new ABI that is supported by
|
|
|
|
|
Clang and Étoilé's LanguageKit and is required for some of the newer features.
|
|
|
|
|
|
|
|
|
|
Although the runtime has been tested by several people, and is being used
|
|
|
|
|
extensively by the Étoilé project, it is entirely new (MIT licensed) code and
|
|
|
|
|
may still contain bugs. If you come across any problems, please report them to
|
|
|
|
|
the GNUstep Developer mailing list <gnustep-dev@gnu.org>.
