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.

Seed7 version 2023-07-09 released on GitHub and SF
This release is available at GitHub and SF. There is also a Seed7 installer for windows, which downloads the newest version from SF. The Seed7 Homepage stays at its usual place. There is also a mirror of the Seed7 Homepage at GitHub.

Seed7 version 2023-04-22 released on GitHub and SF
No. You can see at GitHub that I update Seed7 quite often. Approximately once a month I do a release and this release is announced at r/seed7 and here.
-
Question about installation
The packages are not updated so often. So you are more up-to-date with the releases (or even more up-to-date by pulling from GitHub).
-
Exercism related questions
I committed a corresponding change to GitHub (Support syntax statements without $ (dollar)).

Seed7 version 2023-03-05 released on GitHub and SF
This release is available at GitHub and SF. There is also a Seed7 installer for windows, which downloads the newest version from SF. The Seed7 Homepage stays at its usual place. There is also a mirror of the Seed7 Homepage which uses HTTPS.
-
Have you heard about the Seed7 programming language?
Yes, I am regularly working on improvements for Seed7. The changes are checked in at GitHub (see here for the list of commits) and once a month I do a release which is announced at r/seed7.

Core-js maintainer complains open source is broken
It all depends on the circumstances behind. In the beginning the core-js maintainer had no family and now he has. When I released Seed7 I already had a family. It was clear that my job had to support my family and my hobby (GitHub link).

Seed7 version 2022-06-26 released on GitHub and SF
Syntax highlighting for the Nano editor has been added. Many thanks to Duke Normandin for creating seed7.nanorc.

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:
