  • tomlplusplus

    Header-only TOML config file parser and serializer for C++17.

    • I use them in toml++ to store the path of the source document for all the data nodes parsed from that document. Storing it as a separate std::string allocation for every single object would have been very wasteful, and the alternative would have been to make an overall document class that owned everything, which I didn't want to do, so shared_ptr was a good compromise.
