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 Fennel?
I'm a big fan of moonscript, but occasionally wish it was still be improved and worked on. Yuescript¹ looks like it fixes most of my bugbears with moonscript, and it is largely a faster² drop-in replacement.
There was s little discussion here ~18 months ago³, but it will largely circular if you look as people are suggesting fennel there ;)

² This probably only matters if you have tonnes of moonscript, not just a little neovim/mpv/awesomewm config or something.

Using other languages
There's also some languages made to compile straight to Lua: - MoonScript is the most popular Lua wrapper - it's built to be more Python-like, featuring indentation-based scopes, function calls without parentheses, lambda syntax, list comprehension, and much more. - Yuescript is a modern update to MoonScript that adds more features (I haven't used it myself, so I'm not entirely sure exactly how it differs from MS). - Teal is a version of Lua that adds static typing for better code standards.

Lua, a Misunderstood Language
Yes, this is unfortunately true.
There's a spiritual successor: https://yuescript.org/

I've designed a re-imagined version of the Lua logo and some other Lua flavors just for fun, what do you guys think?

100 Languages Speedrun: Episode 90: YueScript
What I didn't know about is that its fork YueScript is actively maintained, and with some extra features.

Trying to move to Emacs again
I've put together a Lua config with Neovim, but it was still kind of obnoxious to put together. Lua isn't that great of a language, because people seem to forget it's an embed-able language for a reason (it's not supposed to give you tons of features). Using something that makes some of your more complex problems easier like Moonscript or Yuescript can make things more complex in regards to your configuration.

Scriptable Operating Systems with Lua [pdf]
Seems like a perfect use-case for Janet. (https://janet-lang.org/) A fast minimal VM like Lua, but even more extensible than Lua by being a "Lisp" with macro and C extension capabilities. Not a true Lisp, it's very pragmatic and performance-oriented. But it keeps the good stuff.

Ask HN: A Lisp with Cargo/NPM like build system?
You might be looking for: https://janet-lang.org/
It comes with a build tool `jpm` which installs dependencies globally by default, but you can have it be installed in your project folder as well.

Babashka: Fast native Clojure scripting runtime
I like Clojure, but I never had any good opportunities to use it other than for a few small hobby projects. It is unfortunate that it is so huge with tons of dependencies and no simpler native implementation. I started looking at various LISPs and Schemes to find something lighter to use instead and ended up settling for Janet that I think is Clojure-like enough to be comfortable to use, but in a small native binary with no dependencies and can be embedded in other native programs. I am sure for big, real, projects that Clojure makes more sense, but for my hobby projects and scripts I do not think I will install it again. I am still happy for the things I learned from learning Clojure. It was a real eye-opener for an old OO-programmer.

Red Programming Language
Thanks!
I thought about another multiplatform, homoiconic, highly compact language: https://janet-lang.org/ (takes 803 kb on my machine).
It has no types though.

Systems Programming with Racket
Racket is great, and if you like it you might find Rash interesting:

Janet and Gerbil Scheme are also worth a look:

how did you finally reach Lisp enlightenment?
Point here is that, for instance Janet language does not have cons / pair type but tuple (and so is lispoid, not lisp), but clearly this is sufficient for macros & hence seamless language construction: all you need is to be a lispoid although being a lisp gives another useful feature.
