hello,
can anyone tell me if there is something in lua thats similar to an empty define in C?

Usecase is following in C/C++:

//#define DEBUG(x) some_debug_fct(x) //debug case
#define DEBUG(c) //empty in production

i've already tried following

--somename = trace_fct(text)
somename = function () end

but function doesn't seem to be a lightweight operation in lua :-(

It works just fine for me:

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all: Lua 5.1.4 Copyright (C) 1994-2008 Lua.org, PUC-Rio > abc = function() end > abc() > print(abc) function: 0x9f86b58

yes, I didn't mean it's not working just if you use an empty define in C/C++ its less than a NOP instruction.

using following code is far from a nop instruction but really needs cpu power!

abc = function () end
abc()

equivalent to "empty define" in LUA?
