A new version of lgob has been released (grab it here). This version supports some new features of GTK+ 3.10 and has a new and simplified build system. Building lgob on MS-Windows is now easier. There are binaries for MS-Windows here.
By default, lgob does not generates bindings for deprecated functions. In GTK+ 3.10, the stock icons were marked as deprecated, so functions like gtk.Button.new_from_stock() are not generated by default.
lgob is a set of Lua bindings to GObject-based libraries like GTK+ and WebKitGTK+. Almost all functions are wrapped automatically, at compilation time, by using the information provided from the GObject Introspection project.
