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.

Go performance from version 1.0 to 1.22
Would be neat to see graph of recent versions with linear scale
I checked, they use switch on opcodes in vm.go. So would expect a recent improvement, but probably only <5%, & I didn't look close enough to see if awk is one of those languages where instruction dispatch matters less (like how APL tends to avoid issues since array ops avoid having dispatch in tight loops, or how Python avoids instruction dispatch overhead when using numpy)
For VMs Go had a problem for large switch statements: it would always use binary search instead of a jump table. This caused gopher-lua & go-lua to both take the route of having an array of functions which they call on to dispatch instead
A couple years ago this was fixed: https://go-review.googlesource.com/c/go/+/357330
I measured a small perf improvement switching gopher-lua to switch: https://github.com/yuin/gopher-lua/pull/479

Jacobin: Minimal JVM written in Go and capable of running Java 17 classes
Not the parent but there are several high quality native (meaning no CGO) Lua implementations for Go and it's a great choice if you want an embedded scripting language:
https://github.com/yuin/gopher-lua
- Are there any Golang Lua VMs that support snapshotting/serializationi?

Using external Lua libraries in an app with embedded Lua
The "game" was just an example, what I'm exactly trying to do is creating a plugin system for my go app using gopher-lua. The thing is the app will be used by end users and I can't ask them to install libraries. ATM, I don't care about libs with external dependencies like openssl, zlib etc. supporting just the pure Lua ones is enough

Show HN: Supershields.io – smart, Lua-powered SVG status badges
I'm generally using Visual Studio Code for all my development. Really like it.
I chose https://github.com/yuin/gopher-lua as the Lua engine because it is Golang-based, while the Nginx Lua VM is C, unless I'm mistaken. Using gopher-lua is just easier when I'm working in a Golang project. I only have to work in a single language and dev environment for all the backend work. Makes both development and testing easier.
Moonscript I might have heard of, but I have no experience with it. I did not consider it here, and I would rarely consider any niche scripting language for a solution I want others to use. It just introduces an unnecessary barrier to adoption.

Show HN: LadyLua, batteries-included static Lua 5.1 interpreter
GopherLua [0] is a Lua implementation written in Go, not just a wrapper around the C implementation.
The main alternative seems to be Shopify’s go-lua [1], given that Microsoft’s golua [2] is no longer being developed. The main difference between these three implementations seems to be the supported Lua version - 5.1, 5.2 and 5.3 respectively.

Lua: The Little Language That Could
it should be possible, the article mentions https://fengari.io/ (a Lua VM written in JavaScript)

OmG jAVaScRiPt InSeCuRe. LuA bETtEr.
Check out Fengari or Lapis. Fun fact: itch.io is written primarily in Lua, and started by the same person who made Lapis and MoonScript.

Lua is the fourth-fastest growing language on GitHub
I was real excited to see these recently... have you tried any? https://fengari.io/ is the one I was most intrigued by.

How to embed lua in a JS webapp?
Hello, there is also fengari: https://fengari.io/

PyScript
Other languages have done that :)
Lua in the browser: https://fengari.io/
And then you can use that to run Fennel, a Lisp that compiles to Lua https://fennel-lang.org/
I think TypeScript also has a script you can include that lets you put your TS code in a special script tag, and it gets compiled in-browser.

Intro to PyScript: Run Python in your web browser
just use lua, it’s what should have been used for web scripting anyways

Upcoming interview with Roberto Ierusalimschy
Please stop this stuck in the mud nonsense. Anyone stumbling upon lua.org might think the project is dead already. The material is great, close to the best, but its presentation is pure shite. Not mobile friendly (what kinds of device do you think the majority of people in the Global South use?). We live in a world of code highlighting, none of that in PiL. We live in a world where Fengari allows Lua to run in the browser, does that make an appearance on lua.org, allowing users to immediately play with the language? Of course not! It's almost as if the Lua team is trying to push away potential users.

A First Look at PyScript: Python in the Web Browser – Real Python
why not use lua

I really like to think of PyScript as the “Minecraft of software development”
Just use lua https://fengari.io/

What can I create with Lua?
Definitely the most surprising use-case for Lua that I've seen is http://lua.space/webdev/why-we-rewrote-lua-in-js which discusses https://fengari.io/.
What are some alternatives?
go-lua - A Lua VM in Go
pypyjs - PyPy compiled to JavaScript
golua - Go bindings for Lua C API - in progress
pyodide - Pyodide is a Python distribution for the browser and Node.js based on WebAssembly
otto - A JavaScript interpreter in Go (golang)
emscripten - Emscripten: An LLVM-to-WebAssembly Compiler
goja - ECMAScript/JavaScript engine in pure Go
lunatic - Lunatic is an Erlang-inspired runtime for WebAssembly
tengo - A fast script language for Go
wasm-libxml2 - A quick experiment to build and run libxml2 as a WebAssembly module.
go-python - naive go bindings to the CPython2 C-API
