GtkSharp/generator/CallbackGen.cs
Rachel Hestilow e9d1e0b6dc 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.
