Hi,
I'm looking at (say):
template <typename Iterator>
struct employee_parser : qi::grammar
{
employee_parser() : employee_parser::base_type(start)
{
using qi::int_;
using qi::lit;
using qi::double_;
using qi::lexeme;
using ascii::char_;
quoted_string %= lexeme['"' >> +(char_ - '"') >> '"'];
start %=
lit("employee")
>> '{'
>> int_ >> ','
>> quoted_string >> ','
>> quoted_string >> ','
>> double_
>> '}'
;
}
qi::rule quoted_string;
qi::rule start;
};
From http://svn.boost.org/svn/boost/trunk/libs/spirit/doc/html/spirit/qi/tutorial...
I can't find any information as to what "%=" does. I know that from
previous examples
int_ % ","
parses a list of ints separated by commas, but there is no information
as to what %= does. If I took a guess it seems to imply that:
r = r % ","
- is equivalent to -
r %= ","
Can someone point me to some documentation?
Kind regards,
Samuel
