Have a look at these

I think they should be inspiritional and perhaps will help you get started.

Like so:

     *(char_ - eol) >> (eol|eol)

Which means: parse as many non-newline characters as possible till the
end of input or an actual newline.

You can combine it with a skipper, but not with `qi::space` because it
would eat the newline too:

      skip(blank) [ *(char_ - eol) >> (eol|eol) ];
