Description:
C# like language for the GObject system
Vala is a new programming language that aims to bring modern programming language features to GNOME developers without imposing any additional runtime requirements and without using a different ABI compared to applications and libraries written in C. . valac, the Vala compiler, is a self-hosting compiler that translates Vala source code into C source and header files. It uses the GObject type system to create classes and interfaces declared in the Vala source code. This package also contains the vala-gen-introspect and vapigen binaries that will automatically generate Vala bindings.
