How to handle errors properly?

[theonlyasdk]

Assume I try to read a non-existent value from a non-existent section, how would I handle this error? Should I use try/catch? Is there a way I can avoid try/catch? Like a contains(section, key) that returns a boolean, which could possibly be used for catching errors beforehand.

Thanks

Hi @theonlyasdk ,
thanks for using inifile-cpp! The IniFile class is derived from std::map so you can actually use all associated methods and standard library functions with it (see also https://en.cppreference.com/w/cpp/container/map.html).
For example you can check for containement like this:

ini::IniFile myIni;
// do some stuff ...

// check if ini file contains section
const auto section_iter = myIni.find("my_section");
if(section_iter != myIni.end())
{
    const auto &section = section_iter->second;
    // check if section contains value
    const auto value_iter = section.find("my_value");
    if(value_iter != section.end())
    {
    }
}

Oh I see, thank you for this awesome library!
