Hey,

I am the guy behind glad, you are most likely looking for: https://github.com/Dav1dde/glad#d Instead of downloading the glad sources and installing Python you can use the website http://glad.dav1d.de/ (If I have time I will write more documentation and also have it on the website)

glad is just another way to load your OpenGL functions (kinda like Derelict does it), the main difference is, it exactly allows you to generate the feature set you need, if you're in doubt, you can also just generate everything.

Another difference is, it uses the official XML-Specification files, so it is always up to date and doesn't need to be maintained. This also means it can can generate files for EGL/GLES/WGL and GLX.

Glad itself is a library which happens to include a D generator 'backend', that allows you to extend it and make a more advanced loader (e.g. introduce another layer and automatically check glGetError, see C/C++ Debug), but for your normal use the included generator is good enough.

Usage:

Basically you download the zip, add the source files to your project and build system and call gladLoadGL() (check the return value, `enforce(gladLoadGL())`) after creating a context. This will use the internal loader, if you use glfw you can pass glfwGetProcAddress to gladLoadGL(), if you use SDL you can use SDL_GL_GetProcAddress: `gladLoadGL(x => glfwGetProcAddress(x))`.

Then you can just go ahead and call the imported gl functions.

Why no dub?:

Well why would you want to use dub? Just generate the files and copy them into your source.

----

I also wrote glamour, glamour is just a library which abstracts the the OpenGL API and has some glue code for gl3n (maths), SDL (texture loading), glad/Derelict (for gl).


Cool, it looks really well done. I spend several hours researching and looking at various approaches. It was basically Derelict stuff or a lot of things that didn't look well done. I was wishing there was something that would automatically do it(looked into htod, swift, etc)... then I stumbled across your work!!! Was exactly what I wanted!

glfw is separate or have you done something with it(is it wgl?)?

I'm basically trying to get a minimal setup running on winx64. I don't want a lot of hassle that other "solutions" seem to have(no derelict, sdl, etc...). I know there has to be some windows stuff(glfw) haven't yet found a solution for it(haven't really looked yet).

I would recommend using glfw for a context/window, there is a binding in Deimos https://github.com/D-Programming-Deimos/glfw - You need to either compile it yourself or just download the pre compiled package from the website and get the .lib file (http://www.glfw.org/).

There is also an abstraction I wrote once: https://github.com/Dav1dde/glwtf not sure if it still works, it *should*. But even without the abstraction, getting a window and context up with glfw is really easy (documentation is really good! http://www.glfw.org/documentation.html). There is also a C++ example using glad: https://github.com/Dav1dde/glad/blob/master/example/c%2B%2B/hellowindow2.cpp which can easily be ported to D.

Basically all you need is glfw and glad to get started!
