MulleObjC

💎 A collection of Objective-C root classes for mulle-objc

MulleObjC supplies the most basic runtime components like NSObject or NSThread to build a foundation on top of it. MulleObjC depends on standard C libraries only and for instance not on <unistd.h>.

API

Classes

• NSAutoreleasePool - garbage collection
• NSObject - the root class of everything
• NSInvocation - method call serialization
• NSMethodSignature - method description
• NSProxy - the other root class of everything :=)
• NSThread - threads

Protocol and Protocolclasses

• NSCoding - object serialization
• NSCopying - object copying
• NSFastEnumeration - support for for ... in loops
• NSLocking - support for for ... in loops
• NSObject - for objects that don't want to behave like NSObject but can't be them
• MulleObjCClassCluster - enables classes to act as class clusters
• MulleObjCException - enabled a class to act as an exception
• MulleObjCRuntimeObject - documents the minimum required id superset
• MulleObjCSingleton - enables classes to produce singletons
• MulleObjCTaggedPointer - enables classes to use tagged pointers

Functions

• mulle_printf and variants

It does all the interfacing with the mulle-objc runtime. Any library code above MulleObjC ideally, should not be using the mulle-objc runtime directly. Creating a foundation on top of mulle-objc without using MulleObjC is a foolhardy endeavor IMO.

MulleObjC must be compiled with the mulle-clang compiler, or a compiler which supports the metaABI required for the mulle-objc runtime.

Requirements

Requirement	Release Version	Description
mulle-objc-runtime		⏩ A fast, portable Objective-C runtime written 100% in C11
mulle-objc-debug		🐞 Debug support for the mulle-objc-runtime
mulle-objc-cc		⏩ make mulle-clang the default Objective-C compiler
mulle-objc-list		📒 Lists mulle-objc runtime information contained in executables.

Add

Use mulle-sde to add MulleObjC to your project. As long as your sources are using #import "import-private.h" and your headers use #import "import.h", there will nothing more to do:

mulle-sde add github:mulle-objc/MulleObjC

To only add the sources of MulleObjC with all the sources of its dependencies replace "github:" with clib::

Legacy adds

One common denominator is that you will likely have to add #import <MulleObjC/MulleObjC.h> to your source files.

Add sources to your project with clib

clib install --out src/mulle-objc mulle-objc/MulleObjC

Add -isystem src/mulle-objc to your CFLAGS and compile all the sources that were downloaded with your project. (In cmake add include_directories( BEFORE SYSTEM src/mulle-objc) to your CMakeLists.txt file).

Add as subproject with cmake and git

git submodule add -f --name "mulle-objc-runtime" \
                            "https://github.com/mulle-objc/mulle-objc-runtime.git" \
                            "stash/mulle-objc-runtime"
git submodule add -f --name "mulle-objc-debug" \
                            "https://github.com/mulle-objc/mulle-objc-debug.git" \
                            "stash/mulle-objc-debug"
git submodule add -f --name "MulleObjC" \
                            "https://github.com/mulle-objc/MulleObjC" \
                            "stash/MulleObjC"
git submodule update --init --recursive
