GLFW for Crystal

Idiomatic Crystal API to libglfw3. This shard provides an OOP wrapper around libglfw3, to make it easier to write GLFW apps in Crystal.

Installation

Add this to your application's shard.yml:

dependencies:
  glfw:
    github: jellymann/crystal_glfw

Usage

Example code for creating a window (tested on macOS 10.11)

require "glfw"

hints = {
  LibGLFW3::OPENGL_PROFILE => LibGLFW3::OPENGL_CORE_PROFILE,
  LibGLFW3::OPENGL_FORWARD_COMPAT => 1,
  LibGLFW3::CONTEXT_VERSION_MAJOR => 3,
  LibGLFW3::CONTEXT_VERSION_MINOR => 3
}

window = GLFW::Window.new(800, 600, "Hello, Crystal!", hints)

window.make_current

GLFW.swap_interval = 1

until window.should_close?
  window.swap_buffers
  GLFW.poll_for_events
end
