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.

Tokay Programming Language
2 projects | news.ycombinator.com | 12 May 2022
I am very interested in this project as a "better awk" is something I have often fantasized about.
I read all of the documentation that's available on https://tokay.dev/tokay-docs/, but unfortunately it never really... describes itself? Many sections, including the section on "parselets" are just unwritten. "Consumable" values are mentioned but never described (there is a "stub" section that doesn't really explain what the term means).
It begins with a pretty detailed description of value "severity" but doesn't really motivate why the concept exists. (I think that it's (basically) a way to very concisely discard certain matches? When there are "more important" matches around them?)
There are no examples of how I could use Tokay to "parse" something -- there are lots of examples dotted through the docs, but none of them demonstrate working with structured file formats, and they feel a little bit contrived.
I'm not complaining here: this project is not making any false claims about its status, the docs are clearly and explicitly unfinished, it is very clear that Tokay is still under active development.
But I want to learn more about it! I came away from that with a sense that, this has the potential to be really useful to me, but without any concrete evidence to support that. I guess the next step is to download the source and start reading through the tests.
All this to say: please highlight some examples showcasing situations where Tokay shines! (Parsing CSVs containing quoted strings was making the rounds recently, right? What does that look like in Tokay?)
Oh, actually, the GitHub readme has an example that is more involved than any in the documentation: https://github.com/tokay-lang/tokay

Putting the finishing touches on a procedural macro to bind Rust code to koto we want to use in synth. Also a blog post about it is on the way.

I'm currently trying to improve the vtable dispatch in koto (because I want to use it in synth).
Dyon – A rusty dynamically typed scripting language
5 projects | news.ycombinator.com | 21 Dec 2020
I've been working on Koto which is intended for this kind of use case. I've been thinking about extending Rust applications with scripting, and I have games in mind but more generally I'm interested in rapid iteration in creative applications. It's still very early so I haven't shared it more widely but I'd be curious to hear what you think.
