|| ||[ANNOUNCE] Vala 0.5.2 - Compiler for the GObject type system|
|| ||Mon, 01 Dec 2008 21:56:17 +0100|
We are pleased to announce version 0.5.2 of Vala, a compiler for the
GObject type system.
Vala 0.5.2 is now available for download at:
Changes since 0.5.1
* Report uninitialized local variables.
* Report unused fields, methods, and local variables.
* Fix error handling in complex statements.
* Improve support for generic types.
* Support parameter arrays in bindings.
* Do not require libgee for foreach statements.
* Support enums in D-Bus clients and servers.
* Support structs in hash tables in D-Bus servers.
* Experimental static D-Bus client support.
* Add --dump-tree commandline option to write code tree to file.
* Many bug fixes.
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:
* Lambda expressions
* Type inference for local variables
* 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.
