Hi everybody...

I had one of these bugs today where you really wanted to say "doh".. 
I've this nice line splitting routine:

-------------- C++ code --------------
void SplitLine(string s, vector<string>& l, char delim, int times) {
  string::size_type i = 0;
  string::size_type last = 0;
  
  bool ignore = false;

  while(i < s.size()) {
    if(s[i] == '"') {

      if(!ignore) {
        ignore = true;
        last = i + 1;
      }
      else {
        string new_str = s.substr(last, i-last);
        l.push_back(new_str);
        last = i + 2;
        i += 2;
        ignore = false;
      }
    }
    else if(s[i] == delim && !ignore) {
      string new_str = s.substr(last, i - last);
      l.push_back(new_str);
      last = i;
      last++;
    }

    ++i;
    
    if(times > 0 && static_cast<int>(l.size()) >= times) {
      break;
    } 
  }
  if(s.size() - last > 0) {
    cout << last << " " << s.size() << endl;
    string new_str = s.substr(last, s.size() - last);
    l.push_back(new_str);
  }
}
----------------------------

The problem is that this code does not work, since the last
if-block is invoked at times where it should not be invoked.

Can anybody see why? :-)

Bo

(I'll post the solution in a couple of days if I get no response :))
