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.

Lua: The Little Language That Could
I used luajit to write an alternative to bat because it was annoyingly slow for large files. It ended up being like 15 times faster. Such a cool language!

Scintilla is a free source code editing component with a permissive license
There’s a related project that’s really cool called scintillua that lets you use lpeg lexers for scintilla. It supports over 120 languages and it’s super easy to add new ones.
https://github.com/orbitalquark/scintillua
You can also use it as a standalone lua library. I packaged it up to make a faster (but much less feature full) alternative to bat.

Ask HN: What have you created that deserves a second chance on HN?
a fast alternative to bat for syntax highlighting in the command line (eg for fzf preview window)

Building the fastest Lua interpreter automatically
It's super fast and has some really interesting libraries. I used parsing expression grammars to write a faster alternative to bat.

What are the downsides of using Lua?
I recently made a project that uses a lua library to lex source files, then writes them out to stdout with syntax highlighting. Long story short at this point in my code I have a big indexed table of token names and positions. I just iterate over the token names and io.write an ANSI escape sequence that corresponds to the color type of token (simple table lookup), and then io.write the tokenized text.

A Tutorial on Portable Makefiles
I recently learned more Makefiles by using them for a recent project of mine. I wish I had seen this when I was working on it! I learned (stole) from the musl libc configure script and makefile instead.
Makefiles aren't as easy to work with as alternatives in other language ecosystems, but I found they let me do a lot without the need for extra dependencies.
Coincidentally the author of this blog post commented on one of my reddit posts and helped me work out a few kinks in the project.

Seeking feedback on command line syntax highlighter

Ravi is a dialect of Lua, with JIT and AOT compilers
it's based off MIR, does it have something to do with https://mlir.llvm.org/ ?
for typed lua, there is another effort https://github.com/teal-language/tl in addition to the mentioned typescript approach: https://github.com/andremm/typedlua

Lua Criticism Is Unwarranted
I had the pleasure of working with Lua 5.1 back in the late noughties. For me it's replaced Tcl whenever I want something I can configure above a C library. At the time I used it I found it quite nice but I'll also not forget the hours I wasted tracking down nil table corruptions which could have easily been caught by a type checker.
I had some hope that Luau https://luau-lang.org or Teal https://github.com/teal-language/tl would make things better but with the following example
function foo(x: number): string
- Why Fennel?

What's the deal with Fennel in Neovim?
There is already https://github.com/teal-language/tl, which is typed Lua. I think fennel exists to serve a different niche-- personally I use it not for any type features; I just like the syntax better, and others may find certain features like the macro system useful.

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.

Bog – small, strongly typed, embeddable language
Terra and Nelua are both very different in goals than Teal. Teal is literally gradual types integrated into Lua keeping as many of Lua's idioms as possible (to a fault[1]). Terra and Nelua are both very metaprogrammable systems programming languages. Nelua's goals are primarily to soften C's rough edges, comparable to something like Nim.
There's another one you missed in Pallene[2]. But again, it's goal was to optimize the stack sharing involved in using the C API. It also adds types though and maintains Lua idioms as much as possible.
