Julia interface to GLFW 3, a multi-platform library for creating windows with OpenGL or OpenGL ES contexts and receiving many kinds of input. GLFW has native support for Windows, OS X and many Unix-like systems using the X Window System, such as Linux and FreeBSD.

using GLFW
# Create a window and its OpenGL context
window = GLFW.CreateWindow(640, 480, "GLFW.jl")
# Make the window's context current
GLFW.MakeContextCurrent(window)
# Loop until the user closes the window
while !GLFW.WindowShouldClose(window)
	# Render here
	# Swap front and back buffers
	GLFW.SwapBuffers(window)
	# Poll for and process events
	GLFW.PollEvents()
end
GLFW.DestroyWindow(window)

Read the GLFW documentation for detailed instructions on how to use the library. The Julia interface is almost identical to the underlying C interface, with a few notable differences:

• Clipboard (glfwGetClipboard, glfwSetClipboard) and time (glfwGetTime, glfwSetTime) functions have been omitted because Julia's standard library already supports similar functionality.
• glfwInit and glfwTerminate are called automatically using the __init__ and atexit functions. While it is okay to still call them explicitly, it is redundant and not required.
• Thread restrictions are explicitly checked and throw errors when they are not respected. This can be turned off by setting GLFW.ENABLE_THREAD_ASSERTIONS[] = false or by setting an environment variable of the same name.

• Special thanks to @afterwise for writing an early implementation of GLFW 3 support.
