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.

Implementing arrays (and hash tables and ..) in a minimal ML with a C API
Have a look at the ecstasy library for the language definitions of these types.
-
Polymorphic static members
2) Funky interfaces: This is an Ecstasy interface that declares abstract static members (e.g. functions), which can then be implemented on any class and overridden on any sub-class, such that they can be invoked by type (instead of this), and virtually resolved (late bound at runtime) based on the type known at compile time. The best known example, of course, is Hashable, because it has to guarantee that a type implements both equals() and hashCode() on the same class, and the implementation is tied to the type, and not to the this. (C# added a similar feature last year in version 11.)
-
How do you parse function calls?
I'm just going to warn you in advance that invocation is one of the hardest things in the compiler to make easy. In other words, the nicer your language's "developer experience" is around invocation, the more hell you're going to have to go through to get there. The AST nodes for Name( (NameExpression) and Invoke( (InvocationExpression) alone are 7kloc in the Ecstasy implementation, for example -- but the result is well worth it.
-
What are some important differences between the popular versions of OOP (e.g. Java, Python) vs. the purist's versions of OOP (e.g. Smalltalk)?
Ecstasy uses message passing automatically behind the scenes for asynchronous calls, but the message passing isn't visible at the language level (i.e. there is no "message object" or something like that visible). Basically, all Ecstasy code is executing on a fiber inside a service, and services are all running concurrently, so from any service realm to any service realm, the communication is by message.
-
Is your language solving a real world problem?
Regarding Ecstasy, we did not set out to build a new language; we actually set out to solve a real world problem. Specifically, we wanted to be able to dramatically improve the density of workloads in data centers, by at least two orders of magnitude in the case of lightly used applications. Our initial goal was to create a runtime design that would support 10,000 stateful application instances on a single server. Let's call it the "a10k" problem 🤣 ... a tribute to the c10k problem from 1999. We refer to our goal as "zero carbon compute", i.e. we want to push the power and hardware cost for an application to as close to zero as possible; you can't reach zero, but you can get close. If we succeed, we will help reduce the electricity used in data centers over the next few decades by a significant percentage.

How do you tokenize multi char tokens.
Generally, left to right, one character at a time. If you’re looking for example code, here’s a simple hand-built lexer.
-
Have you written your own language in itself yet?
Parts of Ecstasy are now implemented in Ecstasy. Here's the Lexer, for example.

What languages have been created *specifically* for the purpose of being JIT-compiled?
Ecstasy and the xvm were designed assuming an adaptive runtime compiler (similar in concept to the Hotspot compiler for Java), but not necessarily using a JIT.
-
What are you doing about async programming models? Best? Worst? Strengths? Weaknesses?
A Future reference has the various capabilities that you'd imagine, taking lambdas for thenDo(), whenComplete(), etc. The reference, in the above example, is a local variable, so you just obtain it using the C-style & operator:

Is there a way to do a C style For loop in Python ? (for i=start; i< end; i++)...
(kuroko)[https://github.com/kuroko-lang/kuroko] is basically Python, but C

What is your favourite programming language? (other than Scala)
I would say Kuroko makes more sense ;-P

August 2022 monthly "What are you working on?" thread
Kuroko 1.3.0 gets a release candidate. Lots of big things since 1.2.5, like optimized method invocation, more operator overloads, better support for f-string expressions (format specs, =, faster constructions), a long type with my own bigint implementation (this was the last thing I was still regularly opening Python repls for, so a huge personal win). I also fixed a bunch of little things that have been nagging me, like the compiler can now compile expressions directly, which allowed me to remove the kludge that made the repl work previously. The WASM web repl also got some love with a port of the core of Hiwire from Pyodide, giving a very straightforward interface between JS and Kuroko in a browser - and I rebuilt the web IDE on it. I've also been working on a new compiler, which will hopefully form the basis of 2.0 - and this might be the last 1.x release (though I expect at least a few 1.3.x bug fix releases).

Announcing: PonyOS 8
In case it's not clear, PonyOS is a joke reskin of my serious OS project, ToaruOS. PonyOS gets a new release every April 1st. All of the libraries and applications in ToaruOS are in-house things I built myself - the whole OS is "built from scratch". PonyOS adds ponysay, which is an external app originally written in Python - and in previous releases of PonyOS I shipped the Python version alongside a port of Python 3.6. This release, though, comes with a port to my own language, Kuroko, which is a dialect of Python - a lot of what went into building the PonyOS release this year was getting ponysay to work well.

January 2022 monthly "What are you working on?" thread
Did this year's Advent of Code in Kuroko which sussed out some bugs and missing functionality. Better hashing for tuples, more builtins and methods on standard classes for improved compatibility with Python, general build cleanups. In the later problems, most suffering was caused by the GC, so I'd like to put more thought into collection strategies going forward.
