[cpp-netlib-devel] Help! Grammar for parsing HTTP URLs

[Dean M. B. <mik...@gm...>]

Hi Guys,

I've run into a little conundrum. Here's the problem:

I want to be able to parse optional username and password in an HTTP
url as in 'http://user:password@host/' with Boost.Spirit2x (the one in
Boost trunk). So far every attempt I've tried has brought me
compile-time errors or if I get past the compile errors I see the host
being put in the user field. So far here is my grammar:

                bool ok = phrase_parse(
                        start_, end_,
                        (
                         lit("//")
                         >> -lexeme[*(char_ - ':')]
                         >> -lexeme[':' >> *(char_ - '@')]
                         >> -lexeme['@']
                         >> +(char_ - '/')
                         >> -lexeme['/' >> *(char_ - '?')]
                         >> -lexeme['?' >> *(char_ - '#')]
                         >> -lexeme['#' >> *char_]
                        ),
                        space,
                        result
                        );

I have committed the failing tests and the grammar to the repository
(revision 149, in branches/urllib-dean).

Any Spirit2x users out there willing to lend a hand? Thanks in advance.
