csv_iterator

Header only library that provides an iterator interface to CSV files.

Example:

#include "csv_iterator.hpp"
#include <iostream>
#include <fstream>
#include <string>
#include <vector>

struct Wire {int a; std::string b; int c};
std::ostream& operator<< (std::ostream& os, const Wire& w) {
  return os << w.a << " " << w.b << " " << w.c;
}

int main(int argc, char** argv) {
  using std::string;
  using std::vector;
  using std::stoi;

  // provide a factory to construct the Wire object from the component 
  // fields of the CSV file. 

  auto factory = [] (vector<string> const& fields) {
    return Wire { stoi(fields[0]), fields[1], stoi(fields[2]) };
  };

  typedef csv::iterator<Wire> Iter;
  std::ifstream in ("test/mixed.csv");
  std::copy(Iter(in, factory),
            Iter(),
            std::ostream_iterator<Wire>(std::cout, "\n"));
}
