Preprocessor

The Beef preprocessor is intended for conditionally including blocks of text before the parser runs over it and modifying warning options. It is much less flexible than the C preprocessor and cannot be used for implementing macros or for other “code generation” purposes.

#define - sets the symbol value “X” to true
#endif - ends a #if, #else, or #elif block
#else - processes the block down to the next #endif if the previous #if/#elif was false
#elif - processes the block down to the next #endif if the previous #if/#elif was false and “X” is true
#error - Created error at parse time
#if - processes the block down to the next #endif if “X” is true
#pragma format disable - disable formatting
#pragma format restore - restore formatting
#pragma warning disable - disable warning number X
#pragma warning restore - restore warning number X
#undef - sets the symbol value “X” to false
#unwarn - disables the warning on the next source code line.
#warn - Creates warning at parse time
