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.

Ohm: A library and language for building parsers, interpreters, compilers, etc.
Building an interpreter or a compiler from a grammar is an interesting idea. I can't immediately see how to go about it - the grammar would need to match on SSA or similar.
The examples have a lisp-like interpreter at https://github.com/ohmjs/ohm/blob/main/examples/simple-lisp/... which definitely uses a grammar for parsing and might use a generic AST representation.
Will have to think more - a grammar might be a worthwhile way to specify a nanopass style compiler pipeline.

Is there a generalised, abstract programming language, designed to be specialised to a specific domain?
Look for OMeta and its successor Ohm.

[AskJS] Why does our community hate Operator Overloading?
One more suggestion: Maybe create your own scripting-language using Ohm? The project works in JavaScript, so whatever you created would sit on top of your existing APIs.

A different / new way to write compilers?
OMeta and its successor ohm might provide some interesting ideas.

Always fun to find the first commit:

Neat tool. I write parsers by hand though. More fun, and you can be a lot sleazier.

Ohm – A library and language for building parsers, interpreters, compilers, etc.
I'm so happy to see this on HN. I've used Ohm for several projects. If you want a tutorial for building a simple programming language using Ohm, check out this series I put on GitHub.
