Summer Of Code 2006

The Summer Of Code is a Google program that offers student developers stipends to create new freely available programs or to help currently established projects. It would be an excellent opportunity for GNUstep to fund some developments.


Here are some ideas -- Feel free to add more


  • Bindings, KVO support
    • We need NSController, NSArrayController, NSObjectController, NSTreeController, NSUserDefaultController, NSValueTransformer implementations. NSSortDescriptor has already been implemented by Saso Kiselkov. The current NSTreeController is known to be a bit buggy and have an API a bit flawed, as Apple rushed the release of this class in Mac OS 10.4. It is widely believed that these shortcomings will be fixed in Leopard (10.5), so perhaps we should wait a while.
    • Key Value Observing implementation was written by Richard Frith-Macdonald, and is only about 80% finished. Needs completion and testing.


  • Porting
    • Port WebKit (using GCC 4.x with ObjC++ support)


  • General Improvements
    • Printing Support (better postcript generation, etc.)
    • Cairo backend
    • Windows support
    • GNUstepWeb (add script language support, etc)
    • Finish input server support
    • Compare current API with Tiger's API, indicate which classes are missing, and summarize the current status of the existing ones, then work to complete them... ;) The best would be to have a tool which parses all headers (both from Cocoa and GNUstep) and outputs differences in HTML (XML probably too by the way). This would summarize missing classes, missing or partially implementated methods in existing classes and GNUstep-specific extensions. Eventually we should include links to the related documentation on both GNUstep and Cocoa web sites.


  • AppKit
    • PDFKit wrapper implementation around the Freedesktop Poppler library, probably by wrapping PopplerKit (used in ViewPDF/Vindaloo, a GNUstep PDF Viewer). Afterwards, providing support in AppKit trough NSPDFImageRep would be great.

We need mentor(s) to manage the volunteers...
