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.

Reactive Programming Without Functions
There's also https://github.com/mech-lang/mech which is a sort of descendant of Eve https://witheve.com/ . That too seems to be getting close to hiatus. It's a bit of a shame since it seems like quite a nice paradigm for some stuff like GUIs, interactive stuff, and discrete event simulation, but I suppose the paradigm is both a bit obscure and different enough from everything else that it becomes a "boil the ocean" situation where one or a few people try and hack away but aren't really able to get much traction and eventually tired themselves out.

What features would you want in a new programming language?
You should take a look at the language Iām developing, Mech: https://github.com/mech-lang/mech

How do you think of concurrency and parallelism and what would your dream syntax be for it?
I'm working on a language called Mech (github.com/mech-lang/mech) that is semantically parallel and asynchronous first. You can write something like this:

Mech Lang Spring Update: On the Road Toward Beta!
Hi everyone. I've posted here a couple times about my language Mech, which you can find here. I've just put together an update which I hope this community will find interesting!

Frustration: One Year with R
> HN readers - do you have an "up and coming" language that you think has better structured the fundamentals from R, that you hope will someday have enough capabilities you can use it instead of R?
Hope is the operative word here!
I'm writing a language to compete in this area. It's called Mech and I'll be releasing the first beta in October. You can think of it like Matlab + Excel. It's very fast, has default-parallel semantics for operators and functions, and supports full interactive coding with no startup/compilation latency issues. It's meant for robots, but I've also designed it to be a better Matlab, and I think it should take on R handily. Fair warning, it's public alpha now so error messages are sparse and the happy path is narrow.

Charm 0.4: a different kind of functional language
Charm is a language where Functional-Core/Imperative-Shell is the language paradigm and not just something you can choose to do in Python or Ruby or PHP or JS or your favorite lightweight dynamic language. Because of the sort of use-cases that this implies, it didn't seem suitable to write another Lisp or another ML, so I got to do some completely blank-slate design. This gives us Charm, a functional language which has no pattern-matching, no currying, no monads, no macros, no homoiconicity, nor a mathematically interesting type system ā but which does have purity, referential transparency, immutability, multiple dispatch, a touch of lazy evaluation, REPL-oriented development, hotcoding, microservices ā¦ and SQL interop because everyone's going to want that.

Charm 0.4: now with ... stability. And reasons why you should care about it.
I think it's fair to call this a language announcement because although I've been posting here about this project for a loooong time, I've finally gotten to what I'm going to call a "working prototype" as defined here. Charm has a complete core language, it has libraries and tooling, it has some new and awesome features of its own. So ā¦ welcome to Charm 0.4! Installation instructions are here. It has a language tutorial/manual/wiki, besides lots of other documentation; people who just want to dive straight in could look at the tutorial Writing an Adventure Game in Charm.

Programming in Plain Language?
In my own language there is some syntactic flexibility but the only thing that describe pretty table could mean would be the second of the possibilities above; the first would be expressed by describe prettyTable and the third by describe PRETTY, table. This makes it more readable from the point of view of a coder, and who else is going to want to read it, my mom?

Embedding other languages in Charm: a draft
I've been trying to think of a way of doing this which is simple and consistent and which can be extended by other people, so if someone wanted to embed e.g. Prolog in Charm they could do it without any help from me.

Lazy Let: A Cheap Way and Easy Way to Add Lazyness
Charm does this for declaration of local constants in functions (there are no local variables in functions). So for example if you wanted to write the Collatz function this way (which you wouldn't, it's just a minimal example) then you could do so without worrying about a computational explosion:

I guess it's time for me to put aside my exploration of Charm and set up a collaboration with my son the lyricist.

Global and local variables, a choice of evils
In fact that's how a lot of Charm programs end up getting written, because you want to pass a whole bundle of stuff to the functions. For example.

What the imperative shell of an Functional Core/Imperative Shell language looks like
No, it's "shell" as in "shell of the code". The idea is that the imperative bits of the language, the bits that do the mutation of state and the IO, can can call lovely pure referentially transparent functions. But functions can't call commands (otherwise by definition they wouldn't be pure). So all your imperative-ness is reduced to about 1% of your code which lives right at the top of your call stack --- the "imperative shell" of your code. See [here](https://github.com/tim-hardcastle/Charm/blob/main/examples/adv.ch) for an example. The "imperative shell" is the main function --- all 13 lines of it --- and everything everywhere else is pure and immutable.

What are some cool things you've built using your own language?
I'm not sure what counts as cool. It's just dogfooding at the moment. I did a bunch of other languages (only the BASIC and the Forth are up to date with the current version of the language I think), and I did a tiny adventure game (and used it as the basis for a tutorial).
