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.

Tcl Ported to Go
Is "ported" the right term here? It know the repo's README says "CGo-free port", but this is the C version of TCL transpiled from C to Go (see the ~13MB .go files per platform in the "lib" directory). Which is a very cool idea, and the author has done the same thing with SQLite, to avoid CGo (https://gitlab.com/cznic/sqlite).
Here's a link to his C to Go translator: https://gitlab.com/cznic/ccgo

Go performance from version 1.2 to 1.18
Totally agreed: almost all users (me/GoAWK included) want performance and don't care nearly as much about simplicity under the hood. Simplicity of implementation is of value for educational purposes, but we could easily have a small, simple 3rd party package for that. Go's regexp package is kinda too complex for a simple educational demonstration and too simple to be fast. :-)
I actually tried BurntSushi's https://github.com/BurntSushi/rure-go (bindings to Rust's regex engine) with GoAWK and it made regex handling 4-5x as fast for many regexes, despite the CGo overhead. However, rure-go (and CGo in general) is a bit painful to build, so I'm not going to use that. Maybe I'll create a branch for speed freaks who want it.
I've also thought of using https://gitlab.com/cznic/ccgo to convert Mawk's fast regex engine to Go source and see how that performs. Maybe on the next rainy day...

CGo-free SQLite adds windows/amd64 support
FYI it uses facility to translate C to go (https://gitlab.com/cznic/ccgo), there is a similar project does the same thing (https://github.com/elliotchance/c2go).

We Went All in on Sqlc/Pgx for Postgres and Go
It's not really pure go, it's transpiled using https://gitlab.com/cznic/ccgo
Just about all the code looks like this:
// Call this routine to record the fact that an OOM (out-of-memory) error -
CXGO: C to Go Translator written entirely in Go
It would be interesting to read a comparison against https://gitlab.com/cznic/ccgo

Best regexp alternative for Go. Benchmarks. Plots.
rure-go (regex 1.9.3) - uses the Rust regex engine with CGo bindings. The downside is a Rust library dependency that needs to be compiled;
