[Boost-users] [StringAlgo] Need help to use find_format()

Hi,

I'm having a hard time trying to use the find_format() function
provided in the Algorithm/String library.

In the examples provided in the Concepts page, 2 examples of finder
and formatter are provided: simple_finder and simple_formatter.

The first problem is a typing error in simple_finder that prevents it
form compiling, I've opened a ticket to fix this (#1761).

The second problem is that simple_finder uses a function called
make_range that I can't find anywhere in the Boost headers. What is
this function? Am I supposed to write it myself?

The third problem is that I can't find any example of actual use of
those classes. I thought that this:

find_format(string("foobar"), simple_finder(), simple_formatter());

would compile and run (basically replacing the whole string by the
same string), but after having tried to get rid of the second problem
by de-templatizing the simple_finder to adapt it to string, it doesn't
compile. But maybe I'm wrong in the way I did that:

struct simple_finder
{
    template<typename ForwardIteratorT>
    boost::iterator_range<ForwardIteratorT> operator()(
        ForwardIteratorT Begin,
        ForwardIteratorT End )
    {
        return string( Begin, End );
    }
};

Can anyone help me?
