Question

I am having a file of strings by which I want to create an enum with values named by the strings. For example the list is:

"a" "b" "c" "d" ...

I would like to get an enum like this

enum SomeEnum { a, b, c, d };

Thanks.

You could use X-Macros, then you only need to place your enum/string in the myfile.h.

myFile.h

#ifndef ENUM_CONVERT
#define ENUM_CONVERT(val)  val
#define ENUM_HEADER enum SomeEnum
#endif

ENUM_HEADER
{
ENUM_CONVERT(a),
ENUM_CONVERT(b),
ENUM_CONVERT(c),
ENUM_CONVERT(d)
};

myFile.c

#include "myFile.h"  // This declares the enum
#define MKSTR(a)           #a
#define ENUM_CONVERT(val)  MKSTR(val)
#define ENUM_HEADER        char *myStrList[]=
#include "myFile.h"  // This defines the stringList
