C++ Compile-Time string manipulation

Question

I looked at boost\'s mpl::string, but there doesn\'t seem to be an easy way of converting string literals to the single-quotation-integer-based format of mpl::string. What I

Answer 1

Here is an article regarding the subject: http://akrzemi1.wordpress.com/2011/05/11/parsing-strings-at-compile-time-part-i/. The author implements a simple RPN arithmetic calculator that works during compile-time using user string literals and constexpr. I won't attempt to provide any more summary of the article here.

Answer 2

The short answer is no, there is no easy way. At least not using C++ alone, and at compile time. You can use scripts or some other code generator to produce mpl::strings with the correct literals. C++0x will bring user defined literals [1], that allow an easy manipulation of literals, character by character, for example, using variadic templates.
