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.
Scan through the list of wrappers once, instead of multiple times, in
order to find out which functions use which enums. This speeds up enum
generation tremendously.
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.
OpenTK 1.0 and Xamarin Android/iOS do not use strongly-typed enums for
OpenGL ES. Generate overloads with the "All" enum in order to maintain
compatibility.
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.
New WrapperTypes for convenience functions: ConvenienceReturnType to
replace an "out" parameter by a return value, and
ConvenienceArrayReturnType to replace an out array parameter by a
single return value (array count of 1 only).
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.
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.
