MobileLua is a port of Lua to MoSync, a C/C++ cross-platform development system for mobile devices. This enables Lua to be used on a wide range of mobile devices.

MoSync does not yet support exceptions or setjmp/longjmp, so Lua error handling is replaced with return in case of errors and check for error status. This is not implemented for all error conditions, so for some errors you can get incomplete error information, or in the worst case the program may crash.

The following is a very simple paint application. Supports multi-touch.

-- Fill screen with background color.
Screen:SetColor(255, 255, 255)
Screen:Fill()
Screen:Update()

-- Function that paints a "brush stamp" on the screen.
function Paint(x, y, touchId)
  if touchId == 0 then 
    Screen:SetColor(0, 0, 0) 
  else
    Screen:SetColor(0, 200, 0) 
  end    
  Screen:FillRect(x - 20, y - 20, 40, 40)
  Screen:Update()
end    

-- Bind the Paint function to touch events.
EventMonitor:OnTouchDown(Paint)
EventMonitor:OnTouchDrag(Paint)
