span-lite VS tomlplusplus

Another solution: use std::span (or some alternative implementations if the codebase doesn't use C++20).

For span only span-lite should be suffice https://github.com/martinmoene/span-lite

Unless you want to make your own config file parser as an exercise (which is a good idea) I'd recommend using toml++.

It's a public repo - this one: https://github.com/marzer/tomlplusplus but thank you

For a live demo, see the toml++ homepage: https://marzer.github.io/tomlplusplus/

Added bonus, tomlplusplus is a solid C++ implementation, actively updated, and easy to drop into a project (header only, CMake, vcpkg, Conan, etc.). Very easy to use for what I've needed.

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.

toml++ was both my first 'public'/open-source project, and my first ever attempt at a parser. There's a few things I'd do differently now if I were to write it from scratch, but I've learned a lot along the way (particularly about making things build 'clean' on multiple platforms).
