[Tfug] Developer question

/*
This is a slightly different approach (i.e. depends on calling a run-time
method just as the program starts), but it will ensure that for each
color in color_t there exists a string form:
*/

#include <map>
#include <string>

using namespace std;

enum color_t {
       // By convention, must begin with '0'
       RED = 0,
       GREEN,
       BLUE,
};

// map colors in the enum to strings
map< int, string > colorMap;

#define TO_STRING( x )   #x
#define MAKE_COLOR( color ) ( colorMap[ color ] = string( TO_STRING( color )
) )

// call this before anything else
void init( void ) {

colorMap = map< int, string >();

// color definitions go here as macro code
MAKE_COLOR( RED );
MAKE_COLOR( GREEN );
MAKE_COLOR( BLUE );

}

// main function, etc.
int main( int argc, char** argv ) {

init();

/* Code goes here */
}
