Macros
#define	REAL_VERSION_MAJOR   2026
	Major version (the calendar year).
#define	REAL_VERSION_MINOR   8
	Minor version (the calendar month).
#define	REAL_VERSION_PATCH   17
	Patch version (the release count within the month).
#define	REAL_STRINGIZE_IMPL(x)   #x
	Inner half of the two-level stringize: turns its argument into a string literal.
#define	REAL_STRINGIZE(x)   REAL_STRINGIZE_IMPL(x)
	Stringizes the expansion of x — what the second level buys.
#define	REAL_VERSION_STRING
	The version as "MAJOR.MINOR.PATCH" — derived from the three numeric macros.

Detailed Description

REAL's version macros and the C++20 language-standard guard.

Zero dependency by design: only preprocessor #define / #error, never #include. Every public header includes this first, so the version macros are visible from any entry point (the umbrella real.hpp, the opt-in dfa.hpp, or any sub-header pulled in directly) and the standard guard is evaluated once per translation unit (the include guard deduplicates it). make release bumps the three numeric macros; REAL_VERSION_STRING is derived, never edited by hand.

Macro Definition Documentation

REAL_VERSION_STRING

#define REAL_VERSION_STRING

Value:

        REAL_STRINGIZE(REAL_VERSION_MAJOR) "."    \
        REAL_STRINGIZE(REAL_VERSION_MINOR) "."    \
        REAL_STRINGIZE(REAL_VERSION_PATCH)

The version as "MAJOR.MINOR.PATCH" — derived from the three numeric macros.
