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.

Why the C Language Will Never Stop You from Making Mistakes
Yes, Frama-C uses a plugin architecture, and there are plugins to verify all kinds of things, including functional correctness. The Frama-C tutorials page,
https://frama-c.com/html/tutorials.html
Has a link to the ACSL-by-example PDF which gives examples of creating in C various C++ STL inspired data structures and routines:
https://github.com/fraunhoferfokus/acsl-by-example/blob/mast...
Also, it is less effort to write bug-free code in OCaml than C. The Coq/Gallina proof assistant even has an OCaml-extraction (and also Haskell-extraction) feature where you extract runnable code from a formally verified algorithm in the Gallina specification language. (It's generally easier to proof theorems about code in the theorem prover itself, go figure.) Most of these C verification tools are written in OCaml, not C, with varying levels of assistance from Coq/Gallina.
The main reason the functional languages make it easier is because you generally execute side-effect free functions on data structures to give them the mathematical property you want. For example, you execute a lexicographical sort function on a list of strings and then the strings in the list all satisfy the mathematical property of a total ordering. You don't have to do any reasoning about the "in-between state" where pointers under the hood are being manipulated, and you don't have to add pre-conditions and post-conditions about the global environment if the code is side effect free and does not access non-local memory.

Any tips for how to make moddable games?
As someone said, make the game data-driven is a good first step but I will say, also have some sort of way to add additional game logic. For C++ games, lua is really easy to embed the interpreter in your C++ binary, read in the files from a directory (like /mods) with the C++ filesystem api new in C++17, and it's very easy to use SoL to write an API for lua specific to your game. Many games use lua in this way and it's probably the most common mod path setup.

Script Interoperability
I've only ever done this from C++, but it's using the same lua C library, so should be durable from C as well. You can look up how sol2 or any other wrapper libraries do it.

CBN Changelog: December 3, 2022. Improved LUA support in progress!
This version relies on a Lua C++ wrapper called sol2 to hide Lua stack management from the developer, so creating new bindings can be done by adding a few lines of human-readable C++. It still has to be done manually, but at least sol2 is able to automatically figure out types of objects being bound, so it's not much different from our de-/serialization code.

jluna: a new Julia <-> C++ Wrapper
It is half of a pun as I was inspired by [sol3](https://github.com/ThePhD/sol2) which is a lua <-> c++ wrapper. Sol means sun and the julia c-api prefixes all it's functions with jl, luna means moon so it is pronounced "jay luna"

A new C++ <-> Julia Wrapper: jluna
If you want to be portable I'd recommend C++ and Lua, I used those for years and it runs on everything and there's this most amazing wrapper API which was a huge inspiration
