Welcome to the rubber-generate wiki!

Not much in the way of docs yet, but here’s a sample binding for a class.

Requirements

• Ruby-GNOME2 (including headers – ie. devel package if you installed via deb/rpm)
• Ruby (equally including headers)
• C Compiler (only tested with GCC)

Usage

$ rubber-generate --configure --generate --build vte.cr

Which will generate an extconf.rb file, .rd file and a .c file containing the code.

Syntax

The syntax is a kind of C/Ruby-style hybrid. e.g.

%pkg-config gtk+-2.0
%pkg-config clutter-1.0
%pkg-config clutter-gtk-0.10
%pkg-config cairo
%include clutter/clutter.h
%include clutter-gtk/clutter-gtk.h
%include rb_cairo.h
%name clutter
module Clutter
	array BUILD_VERSION = [ CLUTTER_MAJOR_VERSION, CLUTTER_MINOR_VERSION, CLUTTER_MICRO_VERSION ]
	array BINDING_VERSION = [ 0, 9, 0 ]
	string FLAVOUR = CLUTTER_FLAVOUR
	string COGL = CLUTTER_COGL
	gobject Gtk < GTK_CLUTTER_TYPE_EMBED
		@type GtkClutterEmbed
		def self.init
			gtk_clutter_init(0,NULL);
		end
		def initialize()
			RBGTK_INITIALIZE(self, gtk_clutter_embed_new());
		end
		def ClutterActor*:stage
			return gtk_clutter_embed_get_stage(_self);
		end
	end
	enum Gravity (CLUTTER_GRAVITY_NONE,
  CLUTTER_GRAVITY_NORTH,
  CLUTTER_GRAVITY_NORTH_EAST,
  CLUTTER_GRAVITY_EAST,
  CLUTTER_GRAVITY_SOUTH_EAST,
  CLUTTER_GRAVITY_SOUTH,
  CLUTTER_GRAVITY_SOUTH_WEST,
  CLUTTER_GRAVITY_WEST,
  CLUTTER_GRAVITY_NORTH_WEST,
  CLUTTER_GRAVITY_CENTER)
end

which will produce something along the lines (although it’s in C, not ruby)

module Clutter
	BUILD_VERSION = [ 1, 0, 0 ]
	BINDING_VERSION = [ 0, 9, 0 ]
	FLAVOUR = "glx"
	COGL = "gl"
	class Gtk < Gtk::Widget
		def self.init
			# init clutter
		end
		def initialize()
			# initialize object
		end
		def stage
			# return clutter stage
		end
	end
	class Gravity < RubberEnum
		NONE = 0
		NORTH = 1
		NORTH_EAST = 2
		EAST = 3
		SOUTH_EAST = 4
		SOUTH = 5
		SOUTH_WEST = 6
		WEST = 7
		NORTH_WEST = 8
		CENTER = 9
	end
end
