Re: [Vala] [ANNOUNCE] Vala 0.7.10 - Compiler for the GObject type system

Great, congratulations.

We are pleased to announce version 0.7.10 of Vala, a compiler for the
GObject type system.

Vala 0.7.10 is now available for download at:

Changes since 0.7.9
 * Support coalescing operator ??.
 * Support to_string and bitwise complement with enums.
 * Return handler id when connecting signal handlers.
 * Support struct comparison.
 * Support constructor chaining in structs.
 * Enforce protected member restrictions.
 * Improve performance of flow analysis.
 * Support automatic line continuations in Genie.
 * Improvements to the .gir reader and writer.
 * Add --enable-mem-profiler commandline option.
 * Many bug fixes and binding updates.

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

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

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+. It's planned to provide generated bindings for
the full GNOME Platform at a later stage.

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.
