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?

Answer 1

Try using the debug library.

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

Answer 2

What you asking for is not possible in pure Lua.

If you really need this, try fiddling with Metalua.
