This is an independent implementation of Objective C - independent
|
|
of Stepstone's, NeXT's, GNU's (Free Software Foundation) or SunSoft's
|
|
Objective C implementation.
|
|
|
|
Like the GNU compiler, the "objc" grammar is written in YACC. The lexical
|
|
ananlyzer is written in LEX, and the compiler itself in the Bourne
|
|
shell and in Objective C. (the optional Objective C link editor is
|
|
written in AWK).
|
|
|
|
Includes:
|
|
1. "objc", the actual compiler
|
|
2. "objcrt", the Objective C Runtime Library for "objc"
|
|
3. "objpak", the "Object Pak" Objective C Collection Classes
|
|
4. Source of compiler and "oclib", a set of Objective C classes for
|
|
parsing C (and the Objective C extensions to C)
|
|
NICE FEATURES
|
|
1. Easy to install or to modify.
|
|
2. Works on many systems with the native cc, debugger, profiler etc.
|
|
3. Built-in possibility of tracing Objective C messages.
|
|
4. Straightforward "pure C" messenger; "inline cache" messenger.
|
|
5. All classes get a +initialize message at start-up, rather than
|
|
'each class receives a +initialize before it receives its first
|
|
message'.
|
|
6. Already partial support for C++ compilers (will soon be workable)
|
|
7. Great system for experimentation with your own additions/extensions
|
|
to Objective C ! [ but beware - we are likely to oppose them ]
