I started working on that. I've been reading the Python C
Header generator code and I'm wondering if would be easier to
just re-implement it in D, rather than trying to extend it.
Currently the XML is very C oriented (e.g. has C macros in it),
unlike the OpenGL spec which was written in a language agnostic
way.
The advantages of using the vk.xml is that once the generator
is complete you can easily adapt it for newer revisions of the
spec. Also you have much more freedom in how you can organize
the bindings (split by functions/structs/enums or logically by
e.g. instance, device, command recording, queues,
synchronization, shaders, pipelines, etc.), also it's easier to
do other stuff like using D's builtin types instead of cstdint,
generating ddoc-formatted function/struct/enum documentation
and also ddoc-ed unittests from the spec examples. And maybe
also provide two versions - one with vanilla names (easier if
you are following tutorials) and one that's written in D style
(http://dlang.org/dstyle.html) for those who prefer a more
uniform syntax with the rest of the other D libraries out there.
I have completed the SPIR-V D header (which was trivial to
generate from the .json file) and I'm also hoping to translate
the other stuff from the LunarG SDK like the debug layers (no
auto-generation would be possible there).
Given the advancements in the recent years of the D ecosystem
(dub, high quality doc generators, CT generation of
boilerplate, etc.), I think that D can offer even better
developer experience than C++ for which the API was primary
targeted.
Hey I've started work on a more D like vulkan
http://dpaste.dzfl.pl/1ecfa367b966
I switched to adapting Satoshi bindings
(I gave up on trying to gen it from the xml too much like hard
work
Waaaaay too many inconsistencies )
If you have any further ideas for improvements let me know!
(I think a tool to autogen the descriptor layouts would be awesome
But that will take a while and Uni starts soon so I probably
won't have time)
