Trim regex will now correctly match GetInteger64 and other functions
ending in "64". It also uses a correct ending anchor to avoid matches
in the middle of a function name.
GetBoolean, GetInteger6, GetFixedvOES and Delete* are now matched in
the convenience wrapper generator. Methods returning vectors of fixed
size (e.g. 4 ints) are no longer matched.
The lookup for function overrides and overloads now tries to work
around extension case mismatches (e.g. IBM vs Ibm). This fixes a few
specific cases of missing overrides.
It is now possible to specify multiple overloads for the same function.
This is helpful for maintaining backwards compatibility with previous
releases.
Only Get*, Gen*, Delete* and New* functions get convenience overloads.
This avoids issues with functions such as Rect() that have similar
signatures but cannot use such overloads.
This restriction will be relaxed in the future.
These are convenience parameters for function receiving a size and an
array parameter, like DeleteTextures(int n, int[] ids). The generator
will now add overloads taking a single parameter, such as
DeleteTexture(int id).
CreateCLSCompliantWrappers must always change return types into
cls-compliant types. The reason is that we cannot overload on return
type alone, so we should always choose the compliant version.
Functions returning a value or array via an 'out' parameter will now get a convenience overload that returns the result via a return statement. In the case of arrays, only single-valued arrays will be supported. For example:
void GetIntegerv(enum pname, out int value)
will be get an overload of
int GetIntegerv(enum pname)
This will reduce the amount of helper overloads that must be maintained manually in GLHelpers.cs.
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.
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.
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.
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.
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.
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").
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.
Function overrides are now looked up in the following order: specific
name (e.g. ProgramParameteriARB), extensionless name (e.g.
ProgramParameteri) and generic mame (e.g. ProgramParameter). This
improves the override resolution for functions with multiple extension
forms (core, ext, arb, etc).
An EnumProcessor or FuncProcessor instance is now required in order to
call their Translate*() methods. A number of transformations that
relied on calling the static methods have now been moved inside the
processor classes.
For instance, if we override both ClearBufferfi and ClearBuffer, then
ClearBuffer{i f ui}v will be overriden be ClearBuffer and
ClearBufferfi will be overriden by ClearBufferfi. This allows us to
specialize overrides when necessary.
* EnumProcessor.cs:
* GL2/Generator.cs:
* FuncProcessor.cs: Fixed handling of overrides file: we now add
signatures as requested and reset the stream after we are done
reading the file.
* Structures/Parameter.cs: Avoid qualifying IntPtr fully ((a) it's
unnecessary, since we have "using System;" already and (b) the
namespace qualification is not portable to C++).
