Parsing string, with Boost Spirit 2, to fill data in user defined struct
- by Surya
I'm using Boost.Spirit which was distributed with Boost-1.42.0 with VS2005. My problem is like this.
I've this string which was delimted with commas. The first 3 fields of it are strings and rest are numbers. like this.
String1,String2,String3,12.0,12.1,13.0,13.1,12.4
My rule is like this
qi::rule<string::iterator, qi::skip_type> stringrule = *(char_ - ',')
qi::rule<string::iterator, qi::skip_type> myrule= repeat(3)[*(char_ - ',') >> ','] >> (double_ % ',') ;
I'm trying to store the data in a structure like this.
struct MyStruct
{
vector<string> stringVector ;
vector<double> doubleVector ;
} ;
MyStruct var ;
I've wrapped it in BOOST_FUSION_ADAPT_STRUCTURE to use it with spirit.
BOOST_FUSION_ADAPT_STRUCT (MyStruct, (vector<string>, stringVector) (vector<double>, doubleVector))
My parse function parses the line and returns true and after
qi::phrase_parse (iterBegin, iterEnd, myrule, boost::spirit::ascii::space, var) ;
I'm expecting var.stringVector and var.doubleVector are properly filled. but it is not the case.
What is going wrong ?
Thanks in advance,
Surya
