Partial implementation, gaps and impossibilities noted internally as TODO comments. * CPProgress.j: Introduce CPProgress, modelled on NSProgress. - Count units of work, with fraction completed, finished and indeterminate states. - Compose progress trees through explicit children and the current progress object. - Cancel, pause and resume, with handlers, propagating to children. - Announce unit-count changes through key-value observing across the tree. * CPError.j: Add CPUserCancelledError. * CPItemProvider.j: - Return a CPProgress from each load, counting bytes read for files and aborting the read on cancellation. - Pass file contents to CPData as a binary string rather than a byte array. - Implement -canLoadObjectOfClass: and -loadObjectOfClass:completionHandler:. - Add the CPString (CPItemProvider) reading category. * CPString+Encoding.j: Decode data held as a binary string through a Uint8Array, without building a byte array. * Foundation.j: Import CPProgress.j. * CPProgressTest.j: Add unit tests covering counts, children, the current progress object, cancellation, pausing, observation and user information. * CPItemProviderTest.j: Add unit tests covering read progress, cancellation, completion and string loading.
Requires objj be installed, as well as ojunit, located at http://github.com/cappuccino/ojunit
