About vala
==========

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.

The syntax of Vala is similar to C#, modified to better fit the
GObject type system. Vala supports modern language features as the
following: Interfaces, Properties, Signals, Foreach, Lambda
expressions, Type inference for local variables, Generics, Non-null
types, Assisted memory management, Exception handling, Type modules
(Plugins)

Vala is designed to allow access to existing C libraries, especially
GObject-based libraries, without the need for runtime bindings. All
that is needed to use a library with Vala is an API file, containing
the class and method declarations in Vala syntax. Vala currently comes
with bindings for GLib and GTK+ and many others from the GNOME
Platform.

Using classes and methods written in Vala from an application written
in C is not difficult. The Vala library only has to install the
generated header files and C applications may then access the GObject-
based API of the Vala library as usual. It should also be easily
possible to write a bindings generator for access to Vala libraries
from applications written in e.g. C# as the Vala parser is written as
a library, so that all compile-time information is available when
generating a binding.
