projconf

A Mac OS X command line tool for extracting build settings from Xcode project files and generating .xcconfig files containing the build settings.

Licensed under the MIT license.

System Requirements

This application uses Objective-C literals and therefore it must be compiled with OS X 10.8+.

Building

Clone the repo.
Update the submodules:

git submodule update --init --recursive
Run build script:

./build.sh
The projconf binary is now in the build/ subdirectory.

Using

projconf <projectFile.pbxproj> <outputDirectory>

Example:

mkdir /tmp/configfiles
./projconf /path/to/someproject.xcodeproj/project.pbxproj /tmp/configfiles

Results

There will be one project level xcconfig file for each configuration (Debug, Release, etc) and one target level xconfig file for each target and configuration pair.

Let's say that the project has two configurations; Debug and Release. The project also has two targets; targetA and targetB. Then the following files will be generated:

project-Debug.xcconfig
project-Release.xcconfig
target-targetA-Debug.xcconfig
target-targetA-Release.xcconfig
target-targetB-Debug.xcconfig
target-targetB-Release.xcconfig

File Contents

The xcconfig file contains all user defined build setting variables from the project file, as well as the standard build setting variables defined by Xcode. The output is divided into the same sections as the build settings sections in Xcode and any standard build setting variable that isn't set by the project file is still included in the xcconfig file, but commented out. This is for convenience if they will be set at a later time when all the configuration is done from the xcconfig file.

Here's an example snippet from the Architectures section from a generated xcconfig file.

// --- Architectures ---

  // ADDITIONAL_SDKS = 
ARCHS = armv7
SDKROOT = iphoneos5.1
ONLY_ACTIVE_ARCH = NO
  // SUPPORTED_PLATFORMS = 
VALID_ARCHS = armv7
