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:
    + Always use G_TYPE_CHECK_INSTANCE_TYPE for external symbols
    + When freeing local variables don't stop at "switch" on "continue" [#799]
    + Use array_length of collection variable instead of expression
    + Assign GValue result of function calls to temp-var on copy_value [#819]
    + Real structs are allowed by simple generics and passed as reference [#819]
    + Use G_TYPE_CHECK_INSTANCE_CAST for comparisons with interfaces
    + Include required type-definition when casting from generic pointer [#828]
  - girwriter:
    + Mention that this file is generated and not meant to be modified
    + Properly resolve GLib.TypeInterface instead of hardcoding it
    + Multiple improvements and fixes for e.g. GType classes
  - girparser:
    + Add support for string "ctype" metadata [#793]
    + Skip 'attribute' elements
    + Handle "function-macro" by skipping them [gi#159]
  - parser: Multiple corrections for source-location of code-nodes
  - compiler: Add OptionFlags.NO_ARG to deprecated "--thread" option
  - build: Pass -no-undefined when linking libvalaccodegen [#820]
  - tests: Null-terminate arrays for compatibility test of uint8 / uchar [#809]
