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.

Risor v1.4.0: write scripts for K8s, Vault, and the Go ecosystem
GitHub project here:

Scripting with Go: A Modest Proposal
Take a look at Risor and its pipes capability.
https://github.com/risor-io/risor#quick-example
Stay in the Go ecosystem, but gain pipes, Python-like f-strings, and more.

Risor – Fast and flexible scripting for Go developers and DevOps
All good questions. Risor hasn't really fully "launched" yet and its documentation is incomplete at this point.
GCP and Azure to be added in the coming weeks. Here's a related GitHub issue:
https://github.com/risor-io/risor/issues/65
For now, you can browse the available modules in the source tree here:
https://github.com/risor-io/risor/tree/main/modules
Please open an issue on GH if you have other module requests! MySQL is a logical one but I was waiting for someone to ask :-)

Zygomys: Embedded Scripting Language for Go
Nice. Somehow this is the first time I'm seeing Zygomys.
If you're not in love with the lisp syntax, you might want to take a look at Risor as well.

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:

- 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.
