Thread: Playing with .ini files.

You are indexing into a string called foo, but you create it with a default constructor, which means that all indices are invalid (the string storage doesn't/may not exist). May-be you should append characters to the empty string.

There are also string functions that are able to find '=' characters in the string, and I think stringstream should be able to extract the portion up to the '=' character (getline with delimiter '=').

Edit:
By the way

Code:

ini >> foo;

only reads up to the first whitespace. Use getline to read whole lines.

With stringstreams you could do something like that

Code:

#include <string>
#include <sstream>

/* 
    Parses line, returns id and value by reference
    Returns whether successful
*/
   
bool parse(const std::string& line, std::string& id, std::string& value)
{
    std::stringstream ss(line);
    return std::getline(ss, id, '=') //id read successfully
        && std::getline(ss, value) //value read successfully
        && value.find('=') == std::string::npos //value doesn't contain '='
        && ss.eof(); //nothing left to read (unneeded if line is really one line)
}
