Vala is a programming language that tries to bring modern language features to C, without additional runtime requirements and with little overhead, by targeting the GObject object system. It was developed by Jürg Billeter and Raffaele Sandrini. The syntax borrows heavily from C#. Rather than being compiled directly to assembler or to an intermediate language, Vala is compiled to C which is then compiled with the platform's standard C compiler.

For memory management the GObject system provides reference counting. In C, the programmer must manage the addition and removal of references manually but in Vala the management of these reference counts is automated (provided the programmer uses the language's built-in reference types rather than plain pointers).
To use functionality from native code libraries requires writing vapi files that define the interface to the library. Vapi files are provided for a large portion of the GNOME platform, including GTK+.
