Lua: Get the literal name of the parameter

Question

For example,

function test (a)
    name = nameof(a)
    print(name)
end

test(def) --should print "def"

Are there any lua tricks to implement something similar to the above?

Not that anyone needs to explain why they want to do something; some people get grumpy if they aren't given a real-life example. So:

local function registerTestSuite(suite)
   if (LUnit) then
      LUnit:AddTestSuite(
            HotNReady.."_"..GetVariableName(suite), --HotNReady_PizzaTestSuite
            suite);
   end;
end;

Answer 1

What you asking for is not possible in pure Lua.

If you really need this, try fiddling with Metalua.

Answer 2

Try using the debug library.

You can use debug.getlocal ([thread,] level, local) to get information about a local variable, including its name.
