Basic SDL joypad-driven menu

Basic SDL Joypad-driven Menu

A quickly-hacked Ruby/SDL menu 'system' intended as a front-end for emulator systems on Raspberry Pi.

But given it's simplicity and portability you may just as well use it for anything you like.

Caveats/Notes:

• Will handle only about a dozen items (no paging whatsoever)
• Will use first joypad; which button is the 'Enter' button will vary across joypads
• The method to execute a command and then return back is a bit hacky (for a reason)
• The example.rb is the version I use, the sdlmenu.rb can be considered development/debug version
• Font included came with Ruby/SDL, I hope I'm not gonna get sued for that
• Code is not commented... if something is unclear, treat it as an incentive to learn Ruby
• SDL is low-level, and the interface is not fully consistent with itself, oh well...

To configure, edit at least:

FONT = 'sample.ttf' # you'll want absolute path to your TTF font
MENU = [
  ['Menu Item One', 'sleep 5'], # 'Title', 'Command'
  ['Menu Item Two', 'sleep 5'], # and so on...
  ['Exit', nil],                # nil command means exit
]
