Hello
There seems to be a problem with the current release. Typing valac into
the terminal gives:
$ valac
valac: error while loading shared libraries: libvala-0.10.so.0: cannot
open shared object file: No such file or directory
The problem didn't exist with vala-0.9.4, which is the last version
before 0.9.6 that I used.
Anybody else has this issue?
Regards
Jörn
We are pleased to announce version 0.9.6 of Vala, a compiler for the
GObject type system.
Vala 0.9.6 is now available for download at:
http://download.gnome.org/sources/vala/0.9/
Changes since 0.9.5
* Drop deprecated support for assigning to construct properties.
* Some refactoring in the code generator.
* Bug fixes in bindings and vapigen.
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.
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.
