Valar: http://github.com/danlucraft/valar/tree/master

It's rb++ but for the Vala language.

Vala (live.gnome.org/Vala) is a C#-like language with automated memory 
management and collections like ArrayLists and HashMaps. Vala compiles 
into C so is pretty performant.

ValaR makes it dead simple to write Ruby extensions in Vala. Compile 
your vala code into a library and point valar at the generated vapi 
file. Vala will generate the C glue code to allow you to call your Vala 
library from Ruby.

Features:

 * automated conversions between Vala and Ruby types.
   e.g.
     int -> Integer,
     string -> String,
     ArrayList<string> -> ["foo", "bar", ...],
     HashMap<int, string> -> {1 => "foo"}

 * An object oriented Ruby API. Instead of RSTRING_PTR(str),
   you can write str.to_vala()

 * Ruby types. So instead of VALUE, VALUE, VALUE, you
   write Ruby.Value, Ruby.Array, Ruby.String and enjoy automatically
   generated type checking to rule out segfaults.

 * Automated memory management, linked to the Ruby garbage collector.

It's dependent on Ruby-Gnome2 and isn't packaged as a gem yet, my bad. 
Also I'm writing a tutorial on how to get it working which I will link 
to in the readme soonish.

best,
Dan
