vala 0.54.9

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

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

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.


 * Various improvements and bug fixes:
  - codegen:
    + Correctly set array-length for NoAccessorMethods properties [#1316]
    + Detect usage of static type-parameter in runtime context [#1326]
  - vala:
    + Improve accessibility check inside member initializer [#1300]
    + Don't allow nullable enum value as real GObject property [#1074]
    + Avoid critical in SourceFile.get_mapped_length() [#1330]
    + Don't unconditionally expect ObjectType of Class [#1341]
    + Make try-statement parsing more resilient [#1304]
    + Avoid problems with '\' in #line directives on Windows [#1353]
  - gidlparser: Set source reference of parameters
  - valadoc: Include path to doclet in error message
  - manual: Update from

 * Bindings:
  - atspi-2: Fix a few binding errors
  - glib-2.0: Add abs() to int8/int16/int32/ssize_t [#1328]
  - glib-2.0: Use g_abort for GLib.Process.abort() beginning with 2.50 [#1350]
  - gtk+-3.0: Correctly unhide BindingSet.by_class to avoid Version attribute
