Project idea: .love -> .lua

I’ve started learning about the 2D-games-development environment called LÖVE at

Basically, it wires together lots of “de facto standard” multimedia libraries (like SDL/OpenGL, OpenAL, DevIL) and ties it up with the minimalistic scripting language Lua (visit

I really like the idea, and have brought up the “Hello World” on my screen in less than 5 minutes from visiting the page.

Now the downside of this is the syntax of Lua:

function hypot(a, b)
  return math.sqrt(a*a + b*b)

While that doesn’t look so scary, I’m not fond of long keywords (function) nor words-as-end-markers. It gets especially visible/cumbersome if you have a couple of nested levels of control code:

function myfunc(a, b)
  if a>b then return end
  while a<b do
    if a==b then
      for i=0,4 do
    a = a + 1

I like Pythons syntax much better:

def hypot(a, b):
    return math.sqrt(a*a + b*b)

The second example in Python:

def myfunc(a, b):
  if a>b: return
  while a<b:
    if a==b:
      for i in range(5):
        print i
    a = a + 1

Some might say I’m crazy, but then you haven’t coded that much in both these languages. While I can’t say I’ve coded *much* in both, I do have at least some weeks of effective time in both. These little things do make a difference.

So this is a project idea: write a simple translation program from a Python-influenced Lua dialect, into pure Lua. Let’s end files in this new language with “.love” just for the sake of the newly discovered LÖVE library. What the translator would do is simply translate “def” to “function”, and keep track of when an indentation-block ends, so it can add the appropriate “end” keywords a la Lua.

You up for it?
