Choc

choc is a tool to remove object files from as iOS library or framework. It'll automatically scan, dissect, remove unneeded object files from the library and then repack it back to the universal library.

CocoaPods has eliminated the friction of including dependencies to your iOS application. But what happens if your project is a legacy code which embeds a static fat (a.k.a. universal) proprietary framework or library which embeds another common opensource libraries inside their proprietary libs. This leads to problem like duplicate object files and versioning.

This small program will help you remove the unneeded objects and you can delegate the deps to CocoaPods and update the dependencies as needed. This tool was born because of my frustation when doing contract work and finding out many people includes compiled open source files to their proprietary libraries preventing the client to update it.

Installation

Choc is packaged as RubyGems. You can install it using gem command

$ gem install choc
$ rbenv rehash          # if you're using rbenv

From Source

$ bundle install
$ gem build choc.gemspec
$ gem install choc-0.1.0.gem

Usage

Choc needs two input library and the object filenames to be removed

$ choc <library name> [<object list>...]

Example: static universal library

$ choc libProprietary.a JSONKit.o

Example: static framework

Usually the same with static universal library. Framework is just a directory. It usually located in the Versions/A/ and symlinked to Versions/Current

$ choc Proprietary.framework/Versions/A/Proprietary JSONKit.o

TODO : In the future this will be automatically detected
