## Dynamic and static bindings to nanovg, compatible with -betterC, @nogc, and nothrow.

- based on [DerelictNANOVG](https://github.com/aldocd4/DerelictNANOVG)

- use [arsd:official:nanovega](https://code.dlang.org/packages/arsd-official%3Ananovega) when druntime is available instead.

An example with glfw

```d

import core.stdc.stdio;

import bindbc.nanovg;

import bindbc.glfw;

import bindbc.opengl;

@nogc nothrow:

int initNanovg(){

    version(BindNanovg_Static){

    	 // todo: some stuff

    }else{

    	NanovgSupport ret = loadNanovg();

        if(ret == NanovgSupport.noLibrary){

            printf("noLibrary \n".ptr);

            return 1;

        }

    }

    

    return 0;

}

bool exit;

extern (C) void key_callback(GLFWwindow* window, int key, int scancode, int action, int mods) 

{

    if (key == GLFW_KEY_ESCAPE && action == GLFW_PRESS)

        exit = true;

} 

extern (C) int main()

{

    initNanovg();

    exit = false;

    GLFWSupport glfw = loadGLFW();

	printf("GLFW: %d", glfw);

	

	if(!glfwInit()){

		return -1;

	}

	if(!glfwInit()){

	}

	enum glVersion = 32;

	

	glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, glVersion / 10);

	glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, glVersion % 10);

	glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);

	glfwWindowHint(GLFW_RESIZABLE, false);

	glfwWindowHint(GLFW_SAMPLES, 4);

		

	auto window = glfwCreateWindow(1024, 768, "D yellow rect with nanovg", null, null);

	//writeln(window is null);

	glfwMakeContextCurrent(window);

	glfwSwapInterval(false);

	

	glfwSetKeyCallback(window, &key_callback);

	// You have a context, you can load opengl

	GLSupport gl = loadOpenGL();

	

	//writeln("Opengl: ", gl);

	auto vg = nvgCreateGL3(NVG_STENCIL_STROKES | NVG_DEBUG);

	while(!exit)

	{

		glViewport(0, 0, 1024, 768);

		glClearColor(0.3f, 0.3f, 0.32f, 1.0f);

		glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT|GL_STENCIL_BUFFER_BIT);

		nvgBeginFrame(vg, 1024, 768, 1);

		{

			nvgBeginPath(vg);

			nvgFillColor(vg, nvgRGBA(255,192,0,255));

			nvgRect(vg, 200, 200, 300, 300);

			nvgFill(vg);

		}		

		nvgEndFrame(vg);

		

		glfwSwapBuffers(window);

		glfwPollEvents();

	}

	nvgDeleteGL3(vg);

	

	return 0;

}
