Simple string parsing with C++

Question

I\'ve been using C++ for quite a long time now but nevertheless I tend to fall back on scanf when I have to parse simple text files. For example given a config

The C++ String Toolkit Library (StrTk) has the following solution to your problem:

#include 
#include 
#include "strtk.hpp"

int main()
{
   std::string file_name = "simple.txt";
   strtk::for_each_line(file_name,
                       [](const std::string& line)
                       {
                          std::deque token_list;
                          strtk::parse(line,"[]: ",token_list);
                          if (token_list.empty()) return;

                          const std::string& key = token_list[0];

                          if (key == "foo")
                          {
                            //do 'foo' related thing with token_list[1] 
                            //and token_list[2]
                            return;
                          }

                          if (key == "bar")
                          {
                            //do 'bar' related thing with token_list[1]
                            return;
                          }

                       });

   return 0;
}
