Signatures were split into 4 APIs before (gl, glcore, gles1, gles2).
However, gles2 contains bindings for both version 2.0 and 3.0. The
version information is now maintained, which allows us to cut down on
the number of generated enumerations.
Now that we support function overloads, it is safe to ignore functions
that are defined multiple times. We just merge their Category
properties if they are not identical.
It is now possible to define multiple overloads of the same function,
each with different parameters. This is extremely useful for
maintaining backwards compatibility in the face of the changes between
GL 4.3 and 4.4.
Tokens are now sorted according to their value, exactly is in the
upstream gl.xml spec. Additionally, gles1 and gles2 now include the
pre-defined groups in the specification.
Sometimes elements in overrides.xml contain extra spaces due to typos,
which are quite difficult to track down. The XmlSpecReader can now
cope with that.
OpenTK does not currently support generating bindings for pointers of
order 3 or higher. No OpenGL or OpenGL ES API currently uses such
pointers, so we just issue a warning message if such an API is
encountered in the future.
The registry reuses the "gles2" apiname for both OpenGL ES 2.0 and 3.0.
The generator will now use the apiversion attribute to distinguish
between the two APIs.
As a sideeffect of the group element definition, the parser will
convert a ptype of "const GLubyte *" with a group of "String" to
"String *", which is not the correct result. GLXmlParser will now
detect and fix this condition that affects the GetString function of
families.
GetOverridesPath encapsulates the code that retrieves an override enum
or function from overrides.xml. Additionally, it now supports names and
extensions with multiple values (e.g. extension="Core|Ext").
GLXmlParser now explicitly marks its output with version="2", while
the older .spec parsers produce version="1" signatures. The binding
generator uses the newer API to support multiple apinames in the same
file.
Explicit Settings objects are now created for each generator. A new
-mode:all option has been added, which generates bindings for all APIs
in one go (useful for the post-GL4.4 specs, which collect all APIs in a
single file.)
ISpecWriter implementations must now store explicit references to a
Settings object. Additionally, all code generation is now handled inside
the ISpecWriter implementation (it used to be scattered over all Type,
Parameter, etc classes resulting in unmaintainable spaghetti code.)
IBind implementations must now store explicit references to Settings,
GLTypes and CSTypes instances. This allows us to use multiple
configurations in the same process.
FuncProcessor now implements all translation logic for types, parameters
and functions. This used to be scattered in the various classes (Type,
Parameter, etc) resulting in a rather disgusting spaghetti. Code
generation has been removed from FuncProcessor and is now handled by the
various language-specific ISpecWriter backends.
This is part of a long-due series of source cleanup patches. ToString()
is no longer used for code generation (code generation is handled by an
ISpecWriter instance.) Enum is no longer public. EnumCollection now
exposes its backing store through an interface, rather than a concrete
class (simpler to change backing store in the future.)
This is part of a long-due series of source cleanup patches. ToString()
is no longer used for code generation (this is handled by an ISpecWriter
implementation). This class is no longer public.
This is part of a long-due series of source cleanup patches. All
translation logic is now part of FuncProcessor. Code generation is now
handled by an ISpecWriter implementation. Minor improvements to
IEquatable and ToString() implementations. Reduced the surface of the
public API.
This is part of a long-due cleanup patch series. All translation logic
is now part of the FuncProcessor. Language-specific code generation is
now part of the ISpecWriter, not the delegate class. Implemented the
IEquatable interface.
