$ gem install glfw3

Intro

GLFW 3 bindings gem for Ruby 2.x.

To install the gem, you'll need GLFW 3 built and installed where pkg-config can find it. You may also want to grab some OpenGL bindings as well.

Once that's taken care of, you can install it simply by installing the gem via RubyGems.org using

$ gem install glfw3

Or by building and installing the gem, making note of the version so you know the gem package to install, like so:

$ gem build glfw3.gemspec
$ gem install glfw3-VERSION-HERE.gemspec

After that, write a quick script to toy with it. For example:

require 'glfw3'
require 'opengl-core'

# Initialize GLFW 3
Glfw.init

# Create a window
window = Glfw::Window.new(800, 600, "Foobar")

# Set some callbacks
window.set_key_callback do |window, key, code, action, mods|
  window.should_close = true if key == Glfw::KEY_ESCAPE
end

window.set_close_callback do |window|
  window.should_close = true
end

# Make the window's context current
window.make_context_current
loop do
  # And do stuff
  Glfw.wait_events
  GL.glClear(GL::GL_COLOR_BUFFER_BIT | GL::GL_DEPTH_BUFFER_BIT)
  window.swap_buffers
  break if window.should_close?
end

# Explicitly destroy the window when done with it.
window.destroy
