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:

- Have any of you designed a conlang, and then designed a programming language based on the conlang or any fictional culture that would use it?

Too many words about Rust's function syntax
I have something similar in kesh, where : is the assignment operator and the type/signature may be "assigned" before the value:
-
Temporal Programming, a new name for an old paradigm
I'm not OP, in case you thought that :) kesh lives here. I tried incorporating some of the ideas discussed here, but posponed it to a later language, which I'm still thinking about.
-
What language features do you "Consider Harmful" and why?
This is a great idea that I've adopted for my PL. I took it a step further and also allow extensions of the core language to be specified, including profiles.
-
Let's talk about interesting language features.
My (non-existing) language kesh, designed to compile to TypeScript, has expression blocks. That was one of my first decisions.
-
October 2021 monthly "What are you working on?" thread
Still no work on a compiler, but more work on the documentation of kesh.
-
What are some simple but powerful compile-to-JS languages I might not know about, or that you are working on (not Elm, Reason, PureScript, or ClojureScript)?
I'm working on kesh, but it's only at the design stage. I have tried to make it simple yet powerful, so I thought I'd mention it even though you can't use it.
-
Why are you building a programming language?
I tried to distill down the most essential features of TS/JS (functional, prototypal) and then come up with new syntax and semantics that was minimal, orthogonal and hopefully easy to learn and use. The result is kesh and na.
-
September 2021 monthly "What are you working on?" thread
I like the way you think. I had the same goal with kesh. A minimal syntax is easier on the eye and lets you focus on the actual code.
-
August 2021 monthly "What are you working on?" thread
I'm only at the drawing board stage of kesh, a simple little PL that one day might possibly transpile to TypeScript. Not a single line of compiler code has been written so far, it's still all about syntax design and exploring ideas. kesh is mostly a pastime activity and something I can ponder over when I'm bored or can't sleep (which may be the reason I can't sleep).
