Stringification Parentheses Elimination

Question

In c I have the following in an existing code base:

#define MYVAR (1)

As you can see this is conforming good practices in C by surrounding the #define with parenthesis (even though I know in this case it makes no difference since the value is not an expression). Regardless I would like to use this in stringification. when I do this:

#define STRINGIFY(x) #x
#define TO_STRING(x) STRINGIFY(x)

const char* mystring = TO_STRING(MYVAR) ;

The resultant string is "(1)". I'd like to eliminate the parentheses without doing the simple:

#define MYVAR 1

Is there anyway to eliminate parentheses during stringification in c?

Answer 1

Just use STRINGIFY x instead of STRINGIFY(x)

#include <stdio.h>

#define MYVAR 1

#define STRINGIFY(x) #x
#define TO_STRING(x) STRINGIFY x

int main(void)
{
    const char *mystring = TO_STRING(MYVAR);

    printf("%s\n", mystring);
    return 0;
}

TO_STRING(x) expands to STRINGIFY (1) when MYVAR is defined as (1)

If MYVAR is defined as 1 without parentheses you get a compile time error.
