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.

Jacobin: Minimal JVM written in Go and capable of running Java 17 classes
https://github.com/Shopify/go-lua
Unless you specifically need a JVM either of these will be a much more practical and mature choice for embedded scripting.
Alternatively if you prefer JS then Otto is a good choice:

Are there any Golang Lua VMs that support snapshotting/serializationi?
Do you know about go-lua? There's a good discussion of various go lua implementations here, including this choice quote:
-
Change go code behaviour at runtime
There are lua and Go-script options. My impression is that a few are well accepted but perhaps just a little less widely used than the first two. I cannot speak from personal experience on them. Shopify has a Lua 5.2 port: https://github.com/Shopify/go-lua and I know https://github.com/bitfield/script is one of the Go-like scripting languages, but I think it's more for a shell script replacement than embedding.

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.

Solving the Expression Problem in Go
Not diminishing the article at all, there's massive value I've gained from leveraging this runtime solution in multiple projects: https://github.com/antonmedv/expr
The language is easy enough for people to pick-up.
- Expr Release v1.15
- Expr v1.14 release: Go expression language
- Expr – expression language with type checker
-
FireScroll - The config database to deploy everywhere (now with conditional statements!)
Uses the [expr](https://github.com/antonmedv/expr) language to achieve this and I've been super happy with the results.

Library to analyze an arbitrary JSON string
I have been using expr (https://github.com/antonmedv/expr) to do something like this for a while. no complains so far.

[gcalc] A simple calculater in golang
If you wanted it to not require putting in the operation first and just accept string equations (without using something like https://github.com/antonmedv/expr) you could parse, tokenize and then process the input.
