Go Bindings for GLFW 3

ATTENTION: As of GLFW 3.1 we break API. See Changelog below.
See here for documentation.
You can help by submitting examples to go-gl/examples.

Remarks

Some functions -which are marked in the documentation- can be called only from the main thread. You need to use runtime.LockOSThread() to arrange that main() runs on main thread.
Installation is easy, just go get github.com/go-gl/glfw3 and be done (GLFW sources are included so you don't have to build GLFW on your own)!
Go 1.4 is required on Windows (otherwise you must use MinGW v4.8.1 exactly, see Go issue 8811).

Example

package main

import (
	"runtime"

	glfw "github.com/go-gl/glfw3"
)

func init() {
	runtime.LockOSThread()
}

func main() {
	err := glfw.Init()
	if err != nil {
		panic(err)
	}
	defer glfw.Terminate()

	window, err := glfw.CreateWindow(640, 480, "Testing", nil, nil)
	if err != nil {
		panic(err)
	}

	window.MakeContextCurrent()

	for !window.ShouldClose() {
		// Do OpenGL stuff
		window.SwapBuffers()
		glfw.PollEvents()
	}
}

Changelog

The revision of GLFW C library used is listed in GLFW_C_REVISION.txt file.

Method window.SetCharacterCallback renamed to window.SetCharCallback.
Method window.SetCharacterModsCallback renamed to window.SetCharModsCallback.
Added Floating and AutoIconify window hints.
Easy go get installation (GLFW source code included in-repo and compiled in so you don‘t have to build GLFW on your own first and you don’t have to distribute shared libraries).
SetErrorCallback This function is removed. The callback is now set internally. Functions return an error with corresponding code and description (do a type assertion to GlfwError for accessing the variables).
Init Returns an error instead of bool.
GetTime Returns an error.
GetCurrentContext No longer returns an error.
GetJoystickAxes No longer returns an error.
GetJoystickButtons No longer returns an error.
GetJoystickName No longer returns an error.
window.GetMonitor No longer returns an error.
window.GetAttribute Returns an error.
window.SetCharCallback Accepts rune instead of uint.
window.SetDropCallback added.
window.SetCharModsCallback added.
PostEmptyEvent added.
Native window and context handlers added.
Constant ApiUnavailable changed to APIUnavailable.
Constant ClientApi changed to ClientAPI.
Constant OpenglForwardCompatible changed to OpenGLForwardCompatible.
Constant OpenglDebugContext changed to OpenGLDebugContext.
Constant OpenglProfile changed to OpenGLProfile.
Constant SrgbCapable changed to SRGBCapable.
Constant OpenglApi changed to OpenGLAPI.
Constant OpenglEsApi changed to OpenGLESAPI.
Constant OpenglAnyProfile changed to OpenGLAnyProfile.
Constant OpenglCoreProfile changed to OpenGLCoreProfile.
Constant OpenglCompatProfile changed to OpenGLCompatProfile.
