Previously, attempting to use an unsupported built in image such as NSActionTemplate would generate an error message that said, "The image “NSActionTemplate” cannot be found." This would lead the user to think that there was something wrong with nib2cib, instead of understanding that only certain built in images are supported (currently NSAddTemplate and NSRemoveTemplate).
With this commit, an attempt to use an unsupported built in image (where built in is assumed to be any name that matches /^NS[A-Z][A-Za-z]+$/) results in the error message "The built in image “<name>” is not supported."
* State *
Previously the Converter class needlessly copied a whole bunch of state from the Nib2Cib class, which was not only poor factoring, but made for easy omissions of state when instantiating a new Converter, such as was done in NSNib.j.
This commit pushes all state not specific to Converter up to Nib2Cib. This allowed removal of redundant code in NSNib -NS_initWithCoder.
* Resources *
Previously it was not possible to use custom images that were located in a framework, because only the app's Resources directory was searched.
This commit automatically searches all frameworks for Resources directories. When a custom image is specified in Xcode, first the app's Resources directory is searched, then all framework Resource directories. Alternately, the specific framework to use can be specified in Xcode by using the form framework@image.
At runtime, the framework is loaded by its identifier (as specified in Info.plist), and if there is no identifier, by searching next to the current AppKit framework.
All of this renders the nib2cib -R option completely obsolete, so it was removed from the NibApplication/Jakefile template.
