json_test_data VS tomlplusplus

>Maybe take a shot at parsing JSON in C++ and see if the nostalgia survives the process.

I have used this library in the past and was actually pretty easy

I used this for JSON last time I wrote any C++ a few years ago and it still seems popular. It seemed sane enough to me.

On the other hand, I'd like to bring in the json library of my choice, e.g. https://github.com/nlohmann/json or https://github.com/danielaparker/jsoncons. So I'd prefer the web server library provides as little as possible in the way of Json support, and certainly doesn't get in the way of using my library of choice. Similarly, I'd like to use my choice of automatic object serialization.

I find openMVG very decent, FTXUI might be a good one and nlohmann's json library is also pretty nice. I don't really know of any project that strictly adheres to the core guidelines, except maybe for some of Jason Turner's (sample) projects.

JSON for Modern C++. Intuitive syntax. Trivial integration. Serious testing. Memory efficiency. Speed.

Please provide us an example of this one minute process you talk about for an example project of opening a JSON file, writing to it and closing it with a library like `nlohmann`s.

Use a small library like this: https://github.com/nlohmann/json

I worked on my partner’s static site generator, rwar, to implement this feature and she worked on my static site generator – palpatine. I was easily able to do this in rwar which is written in Python. However, I realized that this feature was much harder to implement on palpatine which is written in C++. Samina reached out multiple times seeking help for the broken Cmake configurations and for helping in integrating the nlohmann/json library.

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).
