Hi,

I want to create a c++ syntax analysor (for creating auto-completion tools), and to help me, I want to use the boost.spirit library. In order to learn the basics of spirit, I executed this exercise. It is now working but I want to display the tokens' characters instead of counting tokens. The problem is I don't know the properties of the argument passed to my functor (the variable "t" in the code below). What is the type of this variable and what are the public method/attributes we can use on ?
This is the code of my functor :
struct counter{	counter()			: j(0)	{j = new int();}
        counter(const counter &model)			: j(model.j)	{}
        ~counter()	{delete int;}
        template <typename Token>	bool operator()(Token const& t){//I want to know the type of this variable t		++i; ++(*j);		std::ostringstream oss;		oss << "global : " << i << " membre : " << *j;//typeid(t).name();		printf("%s\n", oss.str().c_str());		return true;	}
        int* j;};
The variable t will be relay to my functor by the following tokenize function :
counter* foncteur = new counter();lex::tokenize(first, last,			word_count_functor,			*foncteur);
I still have other questions :
I read a consistent part of the documentation but I have not been able to define the type of regex used by boost.spirit. Which type is it ?
What is the more appropriate function to use to analyse c++ synthax : tokenize or tokenize _and_parse ? You seems to describe tokenize_and_parse as a more powerful tool, but is it possible to define all the syntax of c++ using a parser ?
Could I find an example of c++ syntax analysor using boost.spirit ?
Any help would be appreciate,Cordialy,Guillaume Bersac237bis rue de Pessac33000 Bordeaux06.65.30.89.43
