Hello. I’ve been examining ruby-gtk2 C sources and it very looks like they were generated with some kind of code generation tool. True/False? The reason why I’m asking about this is that I need Scintilla text editing widget, but I can’t find any existing bindings ☹ Also a bit off-topic question: I’ve got a program with embedded ruby interpreter and a some ruby classes/functions/etc… the question is: how do I pass C’s GtkWidget object to Ruby as instance one of the ruby-gtk2 wrapper classes? Thank you. ---

It’s possible they’ve been partially generated with. I for myself remember I wrote a small script converting GTK+ C headers to a Ruby skeleton source. I used it to add some missing stuff for GTK+ 2.6 and later. Then I manually tweaked the generated if necessary. But that kind of thing produces probably source that looks like it was generated.

The resulting bindings are a lot more like C than the existing ruby-gtk2, and you need to cast to and from GValues by hand a lot, but you can create simple working Gtk+ applications. The gem is called gir\_ffi, by the way. It uses ffi to call the c libraries. The source: [https://github.com/mvz/ruby-gir-ffi](https://github.com/mvz/ruby-gir-ffi) Port of green shoes: [GitHub - mvz/green\_shoes at gir\_ffi · GitHub](https://github.com/mvz/green_shoes/tree/gir_ffi) Port of a more classic Gtk+ application: [https://github.com/mvz/pinhole/tree/gir\_ffi](https://github.com/mvz/pinhole/tree/gir_ffi) There may be crashes, there may be core dumps. Comments, questions and suggestions welcome. Regards, Matijs.
