Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Learn Modern C++
I have not done a "desktop" program in 25+ years and never using C++ (or C), since then I'm mostly a web developer (PHP,Elixir, JS, Kotlin etc).
I'm currently doing a C++ audio plugin with the Juce framework.
This website has been a good resource, alongside https://www.learncpp.com
But I was actually close to give up before using those two things:
- https://github.com/nlohmann/json : my plugin use a json api backend and the Juce json implementation is atrocious (apparently because of being born in previous c++ version), but this library is GREAT.
- ChatGPT 4. I'm not sure I would have "succeeded" without it, at least not in a reasonable time frame. ChatGPT 3.5 is slow and does not give good results for my use case but 4 is impressive. And I use in a very dumb way, just posing question in the web UI. I probably could have it directly in MSVC?
Also I must say, for all its flaws, I have a renewed appreciation for doing UI on the web ;)

What C++ library do you wish existed but hasn’t been created yet?
https://github.com/nlohmann/json works well for me

It is either a clever technique or a sad failure
Here is one popular C++ library (nlohmann/json) removing its use.

How to compile project to separate files to prevent having single large executable as a result?
Before going into binary serialization I suggest you to get comfortable with serialization to text. You can try to write your data to text files and read them in again. Then after you get an idea of how this works you can try to use a library that writes to XML or json, e.g. nlohmann json
- What are some ways I can serialize objects?

C++ that allows tracking peer to peer multimedia streaming connections using a Flat File - NOT MySql
Download the single header file json.hpp from https://github.com/nlohmann/json/releases and place it in your project directory or an include directory.

Exemple of a JSON library: https://github.com/nlohmann/json (For XML, there's tinyxml)

XML is better than YAML
NestedText already is the way I use YAML; everything is intepreted as a string. I have some trust in my YAML parser to not mangle most strings. I could use NestedText, but users would be unfamiliar with it, and IIRC the only parsers are in Python. But then I could use StrictYaml too https://github.com/crdoconnor/strictyaml

The new type of SQL injection
you can stick to a subset of YAML syntax (e.g. strictYAML)

DO YOU YAML?
YAML stands for "YAML Ain’t Markup Language" - this is known as a recursive acronym. YAML is often used for writing configuration files. It’s human readable, easy to understand and can be used with other programming languages. Although YAML is commonly used in many disciplines, it has received criticism on the amoutn of whitespace .yml files have, difficulty in editing, and complexity of the standard. Despite the criticism, properly using YAML ensures that you can reproduce the results of a project and makes sure that the virtual environment packages play nicely with system packages. (If you're looking for another way to share environments there are other alternatives to YAML which include StrictYAML (a type-safe YAML parser) and NestedText)

The yaml document from hell
The example you linked provides this as an example of a YAML document that he wants his format to support.

The YAML Document from Hell
That safe subset exists and is implemented in a number of languages. It is called strict-yaml: https://hitchdev.com/strictyaml/

Why JSON Isn’t a Good Configuration Language (2018)
To me those are in the category of "nice to have", and the problem is that every developer has different preferences for these [1] [2]. But the main features of StrictYaml, like supporting comments and less syntactic noise, I think are pretty uncontroversial, and perhaps it's worth it to get people to switch over for those alone. It doesn't need to be perfect, it just needs to be a significant enough improvement over JSON, and I'd say those two features are more than enough
