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.

sketch, sdl2, c2ffi on M1 Mac?
Quickloading :sketch or :sdl2 wants the c2ffi library which seems to be available on neither Quicklisp nor Homebrew. Downloading that library from source and following the build instructions (and several alternative variants found by Googling ) leads to errors like:
-
C Isn't a Programming Language Anymore
> C compiler based tool that outputs DWARF or DWARF-like debug output that actually lays out everything
That sounds like C2FFI: https://github.com/rpav/c2ffi
The only language ecosystem where I've seen it used is Common Lisp. But it emits plain JSON and depends only on LLVM (albeit a specific version thereof), and I don't see any reason why you couldn't build e.g. a Python auto-binding library on top of it.
-
Alternative to ECL?
There is the cl-autowrap that can generate lisp packages from C header filesc- I am unsure if it sticks to ANSI C or goes beyond. It inturn depends on c2ffi for the first time around.

Installing c2ffi on Ubuntu
git clone https://github.com/rpav/c2ffi git checkout -b llvm-11.0.0 refs/remotes/origin/llvm-11.0.0 cd build cmake .. # -DBUILD_CONFIG=Release LIBRARY_PATH=/usr/lib/llvm-11/lib/ make # -j8 sudo checkinstall

Ask HN: Is Lisp Simple?
>Would be interesting to see how the interpreter works actually...
It's quite easy to see, there are interpeters for Lisp in like 20 lines or so.
Here's a good one:
(It has the full code in a link towards the bottom)
There's also this:

Build Your Own Lisp
Here is one implementation of a lisp (mal specifically) in matlab: https://github.com/kanaka/mal/blob/dcf8f4d7b9cf7b858850a04a0...
Only 260 lines of code, pretty concise :)

Found inside my compiler I've been writing for about 2 years
have a look at the crafting interpreters book, plus make a lisp (lisp is a great first language to make a compiler/interpreter for, just google "lisp compiler/interpreter" and you'll find lots of resources)

Crafting Interpreters or Writing an Interpreter in Go? Given context
If you're really okay with the limitations of a tree-walk interpreter, you might want to check out MAL, which will teach you how to write a tree-walk interpreter for a LISP. The code for MAL has been translated to most popular languages, so you can work through the creation of an interpreter in the language of your choice. JLox would give you a bit more detail and a more complex language, but I'm not convinced that it's all that important.

What do I do now?
Write a small programming language (lisp (https://github.com/kanaka/mal) or brainfuck) in C++ to learn the syntax more. This will teach you a lot about programming languages in general.

Can you beat my dad at Scrabble?
So I started some hobbyist game dev using Unity and realised that the full process of making a game has dependencies on a mass of lower-level skills including lighting virtual environments. As a hobbyist photographer I could see some useful analogies from lighting studios and other scenes
So I pivoted, and eventually made money, not from selling a game, but from developing tutorials about digital lighting. I was also able to contribute to a project at work that was making a product based on commercial games engine, not by actually coding it, but by helping to better estimate the costs of the asset generation required.
Coding Unity object scripts in C# also got me back into programming, and I went on to successfully build a self-hosting lisp interpreter following the Make a Lisp guidelines [0].
