If you do code GObject derivated classes using Emacs and is tired of so much typing, find and replace just to declare some classes, you must like my new set of Elisp functions: gobject-class.el
There are 3 helper functions
gobject-class-header class_name parent_class_name- Inserts in the current buffer the stuff you usually put into header (.h) files. These include common used/recommended C-pre-processor macros, typedefs, structs and
G_BEGIN_DECLSandG_END_DECLS gobject-class-code class_name parent_class_name- Inserts in the current buffer the stuff you usually put into code implementation (.c) files. These include
G_DEFINE_TYPE,_class_init(),_init(),_dispose(),_finalize(). gobject-class-generate class_name parent_class_name- This is a combo of the previous, that already split the screen, create the files with gtk/glib name schema. This is what I use most.
(global-set-key [f7] 'gobject-class-generate), or just call them using M-x gobject-class-generate
Please notice that both class_name and parent_class_name expects a string with underscores ("_") separating the namespace and other components. Examples: g_object, gtk_tree_view, ...
Maybe you're interested in my .emacs.
