I've been using this conditional compilation macro trick, as posted by Privalov himself:

Code:

macro define name { name fix defined }
macro ifdef name,condmacro,elsemacro
{
   macro ifdef#name _m elsemacro m_
   macro ifdef#defined _m condmacro m_
   ifdef#name
   purge ifdef#defined
   purge ifdef#name
}

_m fix {
m_ fix }

I use it in this context:

Code:

include "options.inc"
ifdef _RELEASE,include "include/release.inc",include "include/debug.inc"

where options.inc has a single-line: define _RELEASE (or it does not have that line at all).

Everything compiles fine on 1.60, but breaks after. I have only be able to test 1.60 and 1.62, as I have no builds in between those two.

I know there is a new define directive in 1.66, but it should not be a problem since I was actually testing 1.62.

The compile error I get is:

Quote:

ifdef _RELEASE,include "include/release.inc",include "include/debug.inc"
include/macro/macros.inc [199] ifdef [1]:
macro ifdef#name _m elsemacro m_
error: invalid macro arguments.

I switched to using the match directive, but I am still wondering why the above macro can't compile.

What about fix?

It is processed BEFORE all other preprocessing. So:

Code:

macro define name { name fix defined }

will not expand, since fix is processed BEFORE the preprocessing stage ("macro" for example). It's like:

Code:

name fix defined
macro define name { }

in fact, you could put fix anywhere and it wouldn't affect that macro. But it would affect the following data, if it uses that name ("name" in our case).
