[Doxygen-users] Question about Preprocessing

[Zhen Y. <zy...@le...>]

In the doxygen configuration file:

if
ENABLE_PREPROCESSING   = YES
MACRO_EXPANSION        = NO

doxygen will do partially preprocessing. it evaluates conditional
compilation statements (like #if) and evaluates macro definitions, but
it does not
perform macro expansion.

As in the following example:

#define VERSION 200
#define CONST_STRING const char *

#if VERSION >= 200
  static CONST_STRING version = "2.xx";
#else
  static CONST_STRING version = "1.xx";
#endif

The result will be:

#define VERSION
#define CONST_STRING

static CONST_STRING version = "2.xx";

QUESTION:
Is thers any way doxygen can show both case, in both "if" section and
"else" section?
Set MACRO_EXPANSION to YES only show the case in "else" section.

Thank you.
