Summer Of Code Ideas

These are the ideas that were proposed as projects. This section is maintained for historical interest, and to aid planning for the Summer of Code 2008 (if it happens again). If you have a project that would be interesting for next year, feel free to add it here.
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). There's been discussion of a bounty for this, see the mailing list. The WebKit team is willing to help whoever wants to take on this project, please see this email.
- Port the mySTEP changes. Some have already volunteered, but as this is a big project, more help is welcome.
General Improvements
- Printing Support (better postcript generation, etc. see bug #16262)
- MS Windows support (better integration in the MS Windows look and feel, especially the in-window-menu support needs work)
- 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 implemented methods in existing classes and GNUstep-specific extensions. Eventually we should include links to the related documentation on both GNUstep and Cocoa web sites.
- That is being done here on the wiki, see ApplicationKitCompatibility Martin 08:47, 7 March 2007 (CET)
AppKit
- Text System should be cleaned, profiled and finished. Many methods in NSLayoutManager are unfinished or unimplemented, so we currently cannot tweak the test system as much as the one provided by Cocoa. (Quentin Mathe)
- We need NSTypeSetter, NSGlyphStorage, NSGlyphInfo, and NSGlyphGenerator implementations. If NSTypeSetter and NSLayoutManager were implemented, they would probably be used in Etoile. (Quentin Mathe)
- NSTextTable, NSTextTableBlock, NSTextList, & NSTextBlock implementations would also bring the GNUstep text system in line with that of Cocoa as of Mac OS 10.4. The classes could be useful to build a powerful word processor. (Quentin Mathe)
- NSOpenGL Classes could be improved, made compatible with current Cocoa implementations, and further tested (Quentin Mathe)
- NSBitmapImageRep formats: Currenly, we support only reading and writing for TIFF, read-only for GIF, JPEG, PNG, PNM. We would like to have write support for these NSBitmapImageRep categories. Afterwards, SVG reading, then write support, would be nice. (Quentin Mathe)
- NSDatePicker, NSLevelIndicator (and obligatory companion NSCell subclasses) implementations.
- NSFormatter isn't working very well at this time (Quentin Mathe)
Base
- NSDateComponents implementation.
- NSCalendar implementation.
- Finish the NSPredicate implementation. This was partially done by Quentin Mathe, but is untested. The most important part is not done, which is to write a parser and lexer for the custom language used by NSPredicate. Also needed for this are NSComparisonPredicate, NSCompoundPredicate, and NSExpression implementations.
- Test the NSXMLParser Cocoa class wrapper around GSXML, written by Richard-Frith Macdonald. Once this is thoroughly tested, NSXMLDocument, NSXMLDTD, and NSXMLDTDNode, and NSXMLElement, and NSXMLNode implementations may be useful for compatibility.
Core Data
- Saso Kiselkov started implementing this framework. However, NSManagedObjectContext & NSPersistentStoreCoordinator have yet to be tackled according to his web page. Presumably NSPersistentDocument also needs to be implemented.
Misc
- Create a AJAX Framework for GNUstepWeb
- Create Objective-C bindings for DBUS
