## GLFW

[GLFW](http://www.glfw.org/) bindings for Chicken Scheme.

Note that this extension applies to Version 2 of the GLFW library. For
an interface to GLFW Version 3, see the [glfw3][] egg.

### Installation

    $ git clone git://bitbucket.org/evhan/glfw.git
    $ cd glfw
    $ chicken-install

### API

Constant & function names & signatures match those of GLFW.

### Example

    (use gl glfw extras data-structures)
    
    (define *width* 640)
    (define *height* 480)
    (define *colors* '(.2 .4 .6 .8))
    
    (define-external (window_resize (integer width) (integer height)) void
      (gl:Viewport 0 0 *width* *height*))
    
    (define-external (window_charpress (char c) (integer t)) void
      (when (eq? c #\q)
        (exit)))
    
    (glfwInit)
    (glfwOpenWindow *width* *height* 8 8 8 8 8 8 GLFW_WINDOW)
    (glfwSetWindowSizeCallback (location window_resize))
    (glfwSetCharCallback (location window_charpress))
    (glfwSetWindowTitle "CHICKEN PARTY!!!")
    
    (let COLORS!!! ()
      (apply gl:ClearColor (shuffle *colors* random))
      (gl:Clear gl:COLOR_BUFFER_BIT)
      (glfwSwapBuffers)
      (glfwWaitEvents)
      (COLORS!!!))

The heavy lifting was done by Felix Winkelman's [bind egg][], I just fiddled
with the header file and fixed up the output a bit. Bug reports should still go
to me, though.
