glfw

Solod bindings for glfw, a multi-platform library for OpenGL, OpenGL ES and Vulkan development.

Usage

1. Install glfw for your operating system.

2. Install the Solod bindings.

go get solod.dev/glfw@latest

3. Use it in your code.

package main

import (
	"solod.dev/glfw/libglfw"
	"solod.dev/so/c"
	"solod.dev/so/fmt"
	"solod.dev/so/os"
)

func main() {
	if libglfw.Init() == 0 {
		fmt.Println("Can't initialize glfw")
		os.Exit(1)
	}
	defer libglfw.Terminate()
	fmt.Println("glfw version:", c.String(libglfw.GetVersionString()))
}

OpenGL

The bindings cover glfw itself, not OpenGL. glfw opens the window and creates the GL context; the drawing calls (glClear and friends) come from the OpenGL headers, so declare the ones you use in your own package:

//so:include <OpenGL/gl.h>

//so:extern GL_COLOR_BUFFER_BIT
var GL_COLOR_BUFFER_BIT c.UInt

//so:extern glClear
func glClear(mask c.UInt)

Linking them is up to the build: -framework OpenGL on macOS, -lGL elsewhere. See example/simple/extern.go and the Makefile.
