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.

July 2022 monthly "What are you working on?" thread
Last month I worked on the language ABI (Application Binary Interface). This is where I have made an effort to make modules buildable and exportable (into dynamic shared libraries) to the language interpreter. I call the build environment for these modules the SDK (software development kit). It is a Meson project that supports not just Unix based platforms but also Windows. Before this month, one could only export functions in modules, but now one can include classes also. For me this felt very good, as I would expect of a language to support as much in the SDK as possible of the original script-language data types. Here is a link to an example module library written in C that can be compiled for export into the language interpreter: https://github.com/Ricardicus/ric-script/blob/master/src/sdk_lib/ext_lib.c

Building my own programming language using C
I host the source code here at GitHub. There are links to documentation and even an environment where you can test the interpreter on some samples to be found in the README. If you feel like this is an interesting C-project I'd appreciate the dopamine kick of a star over there at the github platform.

January 2022 monthly "What are you working on?" thread
Continued work on my interpreter for [ric-script](https://github.com/Ricardicus/ric-script) which is an interpreted dynamically typed and lazy evaluated language. Imagine Javascript without semicolon and Python without the indentation thing. I build the syntax tree using yacc. Here is a [code sample](https://ric-script-u5ep8.ondigitalocean.app/doc/syntaxwalkthrough.html#class-declarations) where I build an RPN calculator in it. I’d appreciate the dopamine kick of a star if you find the project interesting.

How can I support very big integers?
Thank you all! I have made it work now in my project . A sample script can be found here .

August 2021 monthly "What are you working on?" thread
I continuing with building my first programming language. It is an interpreted dynamically typed and lazy evaluated language. It is like a merge of python and javascript, imagine Python except the focus on indentation. I build the syntax tree using yacc. Here is a code sample where I build an RPN calculator in it. The source repository is here, I’d appreciate the dopamine kick of a star if you like it.

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:
