We should only generate delegates for actual OpenGL entry points, not
for overloaded functions that resolve to the same entry point. This
improves loading speeds and reduces the size of the compiled dll.
SDL_GL_GetCurrentContext will allow us to replace the weird
implementation in Sdl2Factory.CreateGetCurrentGraphicsContext()
and the latter to disable mouse emulation if we wish to.
Conflicts:
Source/OpenTK/Platform/SDL2/Sdl2.cs
WinGraphicsMode no longer creates a temporary context in order to create
the list of available modes. Instead, it requires to be passed an
existing context in its constructor.
WinGLContext now creates one temporary context in its static constructor
and hands that to WinGraphicsMode.
WinFactory no longer supports the CreateGraphicsMode API. This API will
be removed in the future, because the link because contexts and modes
cannot be separated in the general case.
The static initializer of GetCurrentContext would always default to the
desktop PlatformFactory, which caused problems when trying to run OpenGL
ES code on the desktop. The initializer is now removed and
GetCurrentContext is set in the context constructor, before creating any
contexts.
GraphicsMode.Default used to be set to
(DisplayDevice.Default.BitsPerPixel, 16, 0, 0, 0, 2, false) for improved
compatibility with older systems. However, this appears to be causing
issues with specific modern GPUs. Switch the default mode to (32, 24, 8)
until a more proper solution can be found.
Paths that don't define a "version" attribute will now match all
possible versions. This will make it easier to add support for newer
APIs as they are introduced.
After the previous commit, several ES 2.0 functions would refer to
enums found in ES 3.0. These enums have been copied to ES 2.0, either
as core enums or as extensions.
ES 3.0 includes ES 2.0 verbatim. We can significantly reduce
duplication by using the same <replace> node for both APIs. Note that
the enumerations must remain separate, as ES 2.0 and 3.0 support
different tokens.
ContextAttribute.DOUBLEBUFFER is a boolean in SDL (false->single
buffering, true->double buffering). We need to adjust the number of
buffers accordingly (single buffering->1 buffer, double buffering->2
buffers).
The issue is that some display devices report a BitsPerPel value of 0.
It is not clear whether this is a bug in WinDisplayDevice.cs or some
strange windows issue. The implemented workaround adds an entry to the
debug log and hardcodes BitsPerPel to 32 whenever this condition is
encountered. More investigation required.
The <overload> element simplifies the addition of overloads for
backwards compatibility. It is defined similar to the <replace>
element, but instead of replacing the parameters of a function
in-place, it adds a new overload and modifies the overload instead.
Sometimes an enum may reuse the tokens of another enum verbatim
(possibly adding a few extra tokens.) The reuse directive simplifies
the handling of this case:
<enum name="Foo">
<reuse enum="Bar" />
</enum>
Added strongly-typed enums for sections: Vertices, Shaders and
Programs. Added a number of missing enums for ES 2.0. Normalized
several APIs between OpenGL and OpenGL ES.
When a Delegate is defined multiple times in the spec, we should check
if any of these definitions contains a proper Delegate.Version and
store that. This improves the self-documentation aspect of the bindings.
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.
This is part of a long-due source cleanup series. All Translate*()
methods are now part of the FuncProcessor. Additionally, ToString() has
been improved and the IEquatable interface is now implemented.
ParameterCollection now has better control of when its cache should be
rebuilt.
