👒 Objective C with mulle-sde and the MulleFoundation

foundation-developer is a good starting point for Objective-C development with mulle-objc. If you install foundation-developer as a package, you will get all the requirements like mulle-sde and mulle-clang as dependencies with it.

foundation-developer is a collection of mulle-sde extensions to support development of MulleFoundation code. It enables the use of the common #import <Foundation/Foundation.h> in your projects. It is very thin package atop of mulle-foundation-developer.

For further details, use mulle-objc Community as the starting point on the MulleFoundation and mulle-objc in general. See mulle-sde Wiki for an introduction to mulle-sde.

Extension	Type	Description
foundation/objc-developer	meta	Create Objective-C projects

Install

The initial install will only add mulle-sde and mulle-clang to your system. The Foundation itself will be fetched by mulle-sde, when you create a new project (see Usage below).

Check out the Wiki if you want to build the MulleFoundation without creating a mulle-sde project.

Packages

OS	Command
macos	brew install mulle-kybernetik/software/foundation-developer
debian	sudo apt-get -y install foundation-developer (but see below)
ubuntu	same as debian

Debian Mulle kybernetiK and Codeon repositories

For apt installation you need to add the Mulle kybernetiK and Codeon debian repositories first:

wget -O - https://www.codeon.de/dists/codeon-pub.asc | sudo apt-key add -
echo "deb [arch=amd64] http://download.codeon.de `lsb_release -c -s` main" | sudo tee /etc/apt/sources.list.d/codeon.de-main.list > /dev/null
wget -O - "https://www.mulle-kybernetik.com/dists/debian-admin-pub.asc" | sudo apt-key add -
echo "deb [arch=all] http://www.mulle-kybernetik.com `lsb_release -c -s` main" | sudo tee "/etc/apt/sources.list.d/mulle-kybernetik.com-main.list" > /dev/null
sudo apt-get update

Script

mulle-sde provides an installer-all script to install the required commands and foundation-developer into /usr or some other place.

You need to install mulle-clang yourself.

This is suitable for environments without supported package managers:

Install into /usr with sudo

curl -L -O 'https://raw.githubusercontent.com/mulle-sde/mulle-sde/release/installer-all' && \
chmod 755 installer-all && \
sudo OTHER_PROJECTS="MulleFoundation/foundation-developer;latest \
MulleFoundation/mulle-foundation-developer;latest \
mulle-objc/mulle-objc-developer;latest \
mulle-c/mulle-c-developer;latest" \
SDE_PROJECTS="mulle-sde-developer;latest" ./installer-all /usr

Install into ${HOME} (without sudo)

curl -L -O 'https://raw.githubusercontent.com/mulle-sde/mulle-sde/release/installer-all' && \
chmod 755 installer-all && \
OTHER_PROJECTS="MulleFoundation/foundation-developer;latest \
MulleFoundation/mulle-foundation-developer;latest \
mulle-objc/mulle-objc-developer;latest \
mulle-c/mulle-c-developer;latest" \
SDE_PROJECTS="mulle-sde-developer;latest" ./installer-all ~

You need to install mulle-clang yourself.

Docker

There is a Dockerfile in the project.

This will build and run an ephemeral container named foundation on ubuntu:

sudo docker build -t foundation 'https://raw.githubusercontent.com/MulleFoundation/foundation-developer/release/Dockerfile'
sudo docker run -i -t --rm foundation

Usage

Check that the (meta) extensions are found:

mulle-sde extension list

Create an Objective-C executable project

mkdir foo
cd foo
mulle-sde init -m foundation/objc-developer executable

Create an Objective-C library project

mulle-sde init -m foundation/objc-developer -d foolib library

How to write Objective-C

This is a list of resources useful when starting to write Objective-C.

Programming with Objective-C, by Apple

Programming With Objective C covers all the basics. Ignore the chapter about "Blocks", everything else should be fine.

Concepts in Objective-C Programming, by Apple

Concepts in Objective-C Programming is more in-depth and is a good read to understand some terminology used by fellow Objective-C coders. Ignore the chapters "Delegates and Data Sources", "Model View Controller", "Object Modeling", "Outlets", "Receptionist Pattern", "Target-Action", "Toll-Free Bridging"

Learn Objective-C, CocoaDev

Learn Objective-C gives a quick overview of concepts. Ignore the part about "Dot Syntax" though.
