crystal_lib_glfw3 v0.1.1
Crystal LibGLFW3
Note: Original binding was done by jellyman. I have however made a fork with fixes needed as it seems this user is not active anymore on this repo and I can't get my pull requests approved. Hence why this fork is independent of the original.
libglfw3 bindings for Crystal. See also my Idiomatic API which makes these bindings more accessible for Crystalists.

puts "Error #{error}: #{String.new(description.as(UInt8*))}"
}
LibGLFW3.setErrorCallback(error_callback)
LibGLFW3.windowHint(LibGLFW3::OPENGL_PROFILE, LibGLFW3::OPENGL_CORE_PROFILE)
LibGLFW3.windowHint(LibGLFW3::OPENGL_FORWARD_COMPAT, 1)
LibGLFW3.windowHint(LibGLFW3::CONTEXT_VERSION_MAJOR, 3)
LibGLFW3.windowHint(LibGLFW3::CONTEXT_VERSION_MINOR, 3)
window = LibGLFW3.createWindow(800, 600, "Hello Crystal!", nil, nil)
if window
LibGLFW3.makeContextCurrent(window)
LibGLFW3.swapInterval(1)
