Preprocessor macros: how to insert arguments?
- by mhambra
Hi all,
the code has a number of following sections:
int filter;
#ifdef INPUTFILTER_FOO
LOG4CXX_DEBUG(log, "FOO filter used");
filter = F_FOO;
#endif
They are used multiple times in the code (used to provide I/O, threading support etc for all testing configurations), Circa they are essential for debugging but make the code look harsh, want to replace them with macros, one for each category_type namespace.
So, want to expand the following:
MACROSTUFFBAZ(log2, stuff, "BAZ") <- the text part is unique for each class, so it needs to be included in macro too.
to:
#ifdef INPUTSTUFF_BAZ
LOG4CXX_DEBUG(log2, "BAZ stuff used");
stuff = S_BAZ;
#endif
To define macros, plan to use this:
debug.hpp:
#ifdef INPUTSTUFF_BAZ
#define MACROSTUFFBAZ ...
#else
#define MACROSTUFFBAZ
.. no code!
#endif
#endif
(at least this will give a clear overview of the things currently undergoing probation, without seeing them around the code)
