[Boost-users] Re: "string" values at compile time

Hi,

I want to express a "string" value at compile time. I am assuming that I have to go with mpl::vector<char> and then convert it at runtime to its string format.

I think you mean vector_c< char, ... > That is basically the only way to get types that are guaranteed to be different if the contents of the string are different.

I also have tried using

struct TestString { static const char* getName() { return "TestStringName"; } };

and then have the user specify TestString and then I write my other code to call getName() on the type at runtime.

Are these two choices the best I can hope for with regard to compile- time "string" values?

char const test_string[] = "TestStringName"; A pointer or reference to test_string can be used as a template parameter as long as test_string is declared at namespace scope. -- Dave Abrahams Boost Consulting www.boost-consulting.com
