# CocoaPods for Xcode Manage your dependencies, with minimal command line hack-fu ## Features - Downloads and integrates CocoaPods listed in a project's Podfile - Creates podspecs from a template - Shows command output in the window console - Installs documentation (from CocoaDocs) for the CocoaPods used in the open Xcode workspace - Supports using a custom path to your CocoaPods installation - Supports `$GEM_HOME` expansion, `$GEM_PATH` expansion, and `rvm` environments  ## Prerequisites - Xcode 5+ - CocoaPods 0.22.1+, by default expected to be installed to `/usr/bin/pod`. The installation path can be changed by editing `GEM PATH` in the `Product > CocoaPods` menu. More details can be found in the Usage section. ## Install Install via [Alcatraz](http://alcatraz.io/) OR Clone and build the project, then restart Xcode. ## Uninstall Uninstall via [Alcatraz](http://alcatraz.io/) OR Run `rm -r ~/Library/Application\ Support/Developer/Shared/Xcode/Plug-ins/CocoaPods.xcplugin/` ## Usage ### Custom GEM_PATH setting You can specify a custom GEM_PATH in the `Product > Cocoapods` menu. The default is `/usr/bin` and removing a custom value will restore the default. Both `$GEM_HOME` and `$GEM_PATH` are supported, along with `rvm` environments. That means the following settings are valid: ``` /usr/bin /usr/local/bin $GEM_HOME/bin ${GEM_HOME}/bin $GEM_PATH/bin ${GEM_PATH}/bin /SOME_PARENT/$GEM_HOME/bin /SOME_PARENT/$GEM_PATH/bin ``` When specifying `$GEM_PATH` each path component will be expanded during command resolution. That means the following: ``` $GEM_PATH/bin expands to... /Users/jappleseed/.rvm/gems/ruby-2.0.0-p247@my_gemset:/Users/jappleseed/.rvm/gems/ruby-2.0.0-p247@global expands to... /Users/jappleseed/.rvm/gems/ruby-2.0.0-p247@my_gemset/bin:/Users/jappleseed/.rvm/gems/ruby-2.0.0-p247@global/bin ``` During command resolution, each path will be tested (in order) so that the first match is used. Path expansion and command resolution occurs each time before a command is run. For an `rvm` environment, `.ruby-version` and `.ruby-gemset` (in the root project directory) can dynamically alter the environment and Cocoapods supports this behavior. #### Using GEM_PATH with rvm Under most circumstances in an `rvm` environment the following custom `GEM_PATH` setting should be used:  NOTE: Behind the scenes, the `/bin` path element will be converted to `/wrapper` for rvm. If `.rvm` is not found in the expanded path, the `/bin` path element will remain unmodified. ## [Contributors](https://github.com/kattrali/cocoapods-xcode-plugin/graphs/contributors) ## License **cocoapods-xcode-plugin** is [licensed under the MIT open source license](https://github.com/kattrali/cocoapods-xcode-plugin/blob/master/LICENSE).
