# std.metastrings

Templates with which to do compile time manipulation of strings.

template Format(A...)

  Parameters:
  A = tuple of constants, which can be strings, characters, or integral values.
  Formats:
  The formats supported are %s for strings, and %% for the % character.
  Example:

      import std.metastrings;
      import std.stdio;

      void main()
      {
        string s = Format!("Arg %s = %s", "foo", 27);
        writefln(s); // "Arg foo = 27"
      }

template ToString(ulong U)
template ToString(long I)
template ToString(uint U)
template ToString(int I)
