#define __FUNCTION__   __FILE__":"dummyestr(__LINE__)

#define __PRETTY_FUNCTION__   __FUNCTION__

#define ARG_NUMBER   4

The preprocessor generates templates with 1..ARG_NUMBER arguments.

#define dummyestr

(

x

)

dummystr(x)

#define dummystr

(

x

)

# x

#define GENERATE_LOG_TYPES	(		r,
			_,
			t
	)		BOOST_PP_REPEAT(ARG_NUMBER, LOG_TEMPLATES, t)

Calls the macro LOG_TEMPLATES an ARG_NUMBER number of times, each time adding an extra typename argument to the template.

#define GNASH_PLUGIN_DEBUG   1

#define LOG_TEMPLATES	(		z,
			n,
			data
	)

Value:

template<BOOST_PP_ENUM_PARAMS(BOOST_PP_INC(n), typename T)>\
inline void log_##data(BOOST_PP_REPEAT(BOOST_PP_INC(n), TOKENIZE_ARGS, t)) \
{\
   if (GNASH_PLUGIN_DEBUG < 1) return; \
    boost::format f(t0);           \
    using namespace boost::io; \
    f.exceptions(all_error_bits ^ (too_many_args_bit | \
                                   too_few_args_bit | \
                                   bad_format_string_bit)); \
    processLog_##data(f BOOST_PP_REPEAT_FROM_TO(1, \
            BOOST_PP_INC(n), \
            TOKENIZE_FORMAT, t));\
}

#define LOG_TYPES   (error) (debug) (trace)

This is a sequence of different log message types to be used in the code. Append the name to log_ to call the function, e.g. log_error, log_unimpl.

#define TOKENIZE_ARGS	(		z,
			n,
			t
	)		BOOST_PP_COMMA_IF(n) const T##n& t##n

Macro to add a number of arguments to the templated function corresponding to the number of template arguments. Produces code like this: "const T0& t0, const T1& t1, const T2& t2 ..."

#define TOKENIZE_FORMAT	(		z,
			n,
			t
	)		% t##n

This heap of steaming preprocessor code magically converts printf-style statements into boost::format messages using templates. Macro to feed boost::format strings to the boost::format object, producing code like this: "% t1 % t2 % t3 ..."
