tomlplusplus VS tomli

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).

But the whitespace handling involved is an extra complication, at least the provided example fails to be parsed by `tomli`, which is following the currently release TOML spec: https://github.com/hukkin/tomli/issues/199

ini files aren't standardized, the syntax is really "whatever the parser implements". For new projects I recommend using toml instead. It's ini-like, but standardized. Python 3.11 even comes with a builtin parser tomllib (earlier python versions can use tomli, which is what tomllib is based on).

tomllib is primary the library tomli: https://github.com/hukkin/tomli

TOML as a format is by default used by many Python tools, including build tools. This creates a bootstrapping problem for them. Additionally, many popular tools such as flake8 don't include TOML support citing its lack of support in standard library. This PEP proposes to add TOML support to standard library based on tomli which is already used by packages such as pip or pytest.

tomli Relatively fast read-only parsing. Companion library tomli-w for writing.
