Using Boost Tokenizer escaped_list_separator with different parameters

Hello i been trying to get a tokenizer to work using the boost library tokenizer class. I found this tutorial on the boost documentation:

http://www.boost.org/doc/libs/1 _36 _0/libs/tokenizer/escaped _list _separator.htm

problem is i cant get the argument's to escaped _list _separator("","","");

but if i modify the boost/tokenizer.hpp file it work's. but that's not and ideal solution was wondering if there's anything i am missing to get diferent arguments into the escaped _list _separator.

i want to make it split on spaces with " and ' for escaping and with no escape character inside the quoted string.

this is used for a argument parsing system in a ingame console system.

include <iostream>
include <boost/tokenizer.hpp>
include <string>


int main()
{
    using namespace std;
    using namespace boost;
    string s = "exec script1 \"script argument number one\"";
    string separator1("");//dont let quoted arguments escape themselves
    string separator2(" ");//split on spaces
    string separator3("\"\'");//let it have quoted arguments
    tokenizer<escaped_list_separator<char>(separator1,separator2,separator3)> tok(s);
    for(tokenizer<escaped_list_separator<char>(separator1,separator2,separator3)>::iterator beg=tok.begin(); beg!=tok.end();++beg)
    {
    cout << *beg << "\n";
    }
}

the error from visual studio 2005 is error C2974: 'boost::tokenizer' : invalid template argument for 'TokenizerFunc', type expected

EDIT: This question was awnsered by ferrucio and explained by peter thank's everybody.

From stackoverflow

• It seems like you're declaring your tokenizer type incorrectly.

  typedef boost::tokenizer< boost::escaped_list_separator<char> > Tokenizer;
  boost::escaped_list_separator<char> Separator( '\\', ' ', '\"' );
  Tokenizer tok( s, Separator );
  
  for( Tokenizer::iterator iter = tok.begin(); iter != tok.end(); ++iter )
  { cout << *iter << "\n"; }
  

  You want to make a boost::tokenizer< boost::escaped_list_separator< char > > typed object with a boost::escaped_list_separator< char > separator object as its TokenizerFunc.

  Harper Shelby : Those should be single quotes in your constructor - the double quotes are for char*, not char.

• try this:

  #include <iostream>
  #include <boost/tokenizer.hpp>
  #include <string>
  
  int main()
  {
      using namespace std;
      using namespace boost;
      string s = "exec script1 \"script argument number one\"";
      string separator1("");//dont let quoted arguments escape themselves
      string separator2(" ");//split on spaces
      string separator3("\"\'");//let it have quoted arguments
  
      escaped_list_separator<char> els(separator1,separator2,separator3);
      tokenizer<escaped_list_separator<char>> tok(s, els);
  
      for(tokenizer<escaped_list_separator<char>>::iterator beg=tok.begin(); beg!=tok.end();++beg)
      {
          cout << *beg << "\n";
      }
  }
