2002-08-19 Rachel Hestilow <hestilow@ximian.com> * art/Makefile.in (clean): Change to avoid bugging out on generated/CVS. * glib/ObjectManager.cs: Added. Used to be auto-generated, but now it can infer names, and relies on per-namespace ObjectManager classes to inform it of oddly-named classes. * generator/IGeneratable.cs, GenBase.cs: New "DoGenerate" property. * generator/*Gen.cs: Honor DoGenerate. * generator/CodeGenerator.cs: Support including dependency files which will not be generated. * generator/ObjectGen.cs: Generate mapping file per-namespace, as one that calls back to the one in glib. Only generate if the name does not follow the normal conventions, otherwise, GtkSharp.ObjectManager can infer the name. * generator/Parser.cs: Accept 'generate' flag to pass on to the IGeneratables. Parse a new toplevel element, "symbol", which adds a type to the SymbolTable (instead of hard-coding it). * generator/SignalHandler.cs: Do not optimize signal handler creation, instead creating them in their own namespaces. Do not generate if the calling Signal told us not to. * generator/Signal.cs: Do not generate handlers if container's DoGenerate is false. Adjust to the marshaller name being in a sub-namespace. * generator/SymbolTable.cs (AddSimpleType, AddManualType): Used to add simple and manually wrapped types at runtime instead of compile-time. (FromNative): Remove hard-coded cases for manually wrapped types, use a generic case instead. * api: Added. Move api files and generation targets here. * source: Added. Move source parsing here. * generator/makefile: Move actual generation to api/. * glib/Makefile.in: Remove generated/* target. * glue/Makefile.am: Fix to include canvas-marshal. Move canvas stuff to GNOME target. * gnome/CanvasProxy.cs: Update to work with SignalHandlers being namespace-specific. * parser/Metadata.pm: Moved to GAPI/Metadata.pm, renamed, etc. * parser/gapi2xml.pl: Use GAPI::Metadata. * parser/makefile: Install scripts, remove source parse build target. Rename formatXML to gapi_format_xml. svn path=/trunk/gtk-sharp/; revision=6818
