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.

Cwerg: C-like language that can be implemented in 10kLOC
Perhaps these have already been dealt with and I'm missing critical information. If so, my apologies. Great work, in any case.

Where can I find resources and guides on how to build compiler backends?
Cwerg has backend that can be used as JIT and is written with readability in mind. Additional documentation can be found here: https://github.com/robertmuth/Cwerg/tree/master/Docs
- Most important language features not touched in the book "Crafting Interpreters"?
- Lack of resources in creating Assemblers from scratch.
-
Minimum ISA Capabilities to Support Most (Non-Interactive) Programs?
I defined a basic ISA-like IR for Cwerg. It has unlimited registers and no constraints on immediates.

How do you design a compiler and a language?

Syntax Design
I was also going down the path of bike shedding concrete syntax for my language Cwerg before pulling the plug on that effort and just using s-exprs. I managed to make the s-expr quite succinct by carefully choosing the order of arguments so I can omit optional ones. Also very helpful was to use square brackets for list, e.g. (call fun-name [arg1 arg2]). This simplifies parsing a little bit and is easier on the eye. Here are some Code Examples

November 2022 monthly "What are you working on?" thread
I am iterating over the languages features for Cwerg's Frontend which aims to be a low level language with about the complexity of C but with some of the comforts of modern languages. I am especially happy with the choice of adding sum types. Relative to C the current feature set looks like this: Removed: * arrays decay to pointers * bitfields * separate compilation (more of a backend issue) * pre-processor * varargs * implcit type conversions * (untagged) unions * ++/-- * comma operator * implicitly nullable pointers * goto

what is your CI/CD pipeline setup and how are you handling larger binaries? are smaller game dev studios just brute forcing through LFS and building for each test?
Don't get me wrong, I'm a big fan of automated tests where it makes sense. I wrote a scripting language that I use for my personal game projects, and I never would have been able to do it if it weren't for the battery of tests for every feature, error, and corner case I could think of. But games are rarely like other software, with hard rules about what is "correct" or "incorrect". And it would be a nightmare to try to keep up with designers, constantly tweaking and tuning, so what's "correct" is literally a day to day, constantly moving target.

any modern procedural programming languages?
A second trial for you might be Jinx. Depending on your definition of procedural, Jinx is 100% only procedural. https://jamesboer.github.io/Jinx/
-
Which phases/stages does your programming language use?
Jinx (embeddable scripting language) works as following:
- How do I create a file that will automatically compile and run my c++ program when I double click it?
-
Is I already know C and OOP, do I basically already know C++?
Feel free to look at my own interpreter, written in modern C++. You're welcome to ask me if you have any questions.

I'm curious what a gameplay programmer would use a scripting language for
I use my own scripting language more like content, especially for things like one-off events and behaviors. Example: scripting special behaviors for a boss fight, or a room with a unique trap in it, or any other sort of one-off behavior that would be overkill for C++, but too complex for most other types of data-driven content. These days, visual scripting also helps to fill in these gaps between content and procedure.

What are the best free books for learning to write interpreters in C++?
You're welcome to look at my scripting language Jinx, written in modern C++. Just let me know if you have specific questions. Data flow is JxLexer.cpp -> JxParser.cpp -> JxScript.cpp. Most everything else is implementation details. Also, note the parer is pretty complex, mostly because Jinx has a crazily flexible syntax for functions.

Design examples for runtime scripting
Feel free to look at Jinx if you want an example of what I consider a fairly easy-to-use and integrate scripting system. Obviously, I'm a bit biased since I wrote it.
-
Is just UTF-8 support good enough?
If you're working in UTF-8 internally, you could just write your own UTF-16 to UTF-8 conversion functions to convert strings at API boundaries. I did this in my scripting language because I didn't want to bring in dependencies.
