vala 0.52.5

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:
    + Allow null to initialize non-null struct inside initializer list [#594]
    + Implementing GLib.Source.prepare/check is optional since 2.36
    + Fix variadic constructors for compact classes and structs [#1195]
    + Use detroy_value() for delete statement [#1201]
    + Fix params-array in constructor for struct [#1202]
  - vala:
    + Rely on DataType.to_qualified_string() for error-types [#1206]
    + Disallow resize() for constant arrays [#944]
  - Recognize multiple valid CCode.gir_namespace/_version in VAPI files [#1189]
  - Slightly improve source_reference for get_dup_func_expression()
  - girwriter:
    + Respect for constants, errordomains and delegates [#1196]
    + Add explicit writable attribute to all field elements
    + Fix position of "result" parameter for struct constructor
    + Write missing c:type attribute of compact class record
  - girparser: Add support for "final" class attribute
  - tests/girwriter: Add missing [Flags] annotation
  - testrunner: Add support for girwriter tests
  - docs: Update bootstrap instructions in

 * Bindings:
  - Partly revert "gstreamer: Update from 1.19.0+ git master" [#1210]
  - glib-2.0: expected_type and return value of VariantDict.lookup_value()
    is nullable
  - glib-2.0: Add Uri.to_string/to_string_partial() (since 2.66)
  - gobject-2.0: Fix the Closure.invoke() signature
  - gstreamer: Update from 1.19.0+ git master
  - gtk4: Update to 4.3.2+04f3c805
  - linux: Substitute linux/if.h with net/if.h
  - linux: Fix some bindings errors
  - linux: Fix i2c-dev constants
