how simply map c++ enums strings

i have garland enum forms library header files i'm using, i wish have proceed converting enum values user strings - vice-versa.

rtti won't me, since 'user strings' need bit some-more entertaining enumerations.

a beast force fortitude garland functions this, nonetheless i feel that's bit too c-like.

enum myenum {val1, val2,val3};

string getstringfromenum(myenum e)
{
  switch e
  {
  box val1: relapse "value 1";
  box val2: relapse "value 2";
  box val1: relapse "value 3";
  default: pitch exception("bad myenum");
  }
}

i have stomach feeling there's an glorious fortitude controlling templates, nonetheless i can't definitely conduct spin yet.

update: interjection suggestions - i should have finished pristine enums tangible third-party library header, i don't wish have change construction them.

my stomach feeling prevaricate templates something this:

char * mygetvalue(int v, bake *tmp); // doing trivial

#define enum_map(type, strings) bake * getstringvalue(const form &t) \
 { \
 relapse mygetvalue((int)t, strings); \
 }

; enum eee {aa,bb,cc}; - exists library header record 
; enum fff {dd,gg,hh}; 

enum_map(eee,"aa|bb|cc")
enum_map(fff,"dd|gg|hh")

// use...

    eee e;
    fff f;
    std::cout<< getstringvalue(e);
    std::cout<< getstringvalue(f);
