Detailed Description

Represents a parsed #define preprocessor statement.

DefineStatement captures the name and value of a C preprocessor #define directive. For simple numeric defines like #define FOO 123 or #define BAR (1 << 4), the value is evaluated and stored as an integer. For string defines like #define MSG "hello", the string value is stored. For flag-like defines with no value like #define DEBUG, the value is std::monostate.

The original source position is preserved for error reporting.

Example defines this class can represent:

#define FOO 123           // name="FOO", value=123
#define BAR 0xFF          // name="BAR", value=255
#define BAZ (1 << 4)      // name="BAZ", value=16
#define MSG "hello"       // name="MSG", value="hello"
#define DEBUG             // name="DEBUG", value=monostate
