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.

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.

Have you written your own language in itself yet?
Parts of Ecstasy are now implemented in Ecstasy. Here's the Lexer, for example.

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:

FWIW - here is the stage manager code that I referred to.

Ecstasy (xtclang.org): Currently working on session management for a cloud-based HTTP back end. Not exactly compiler or language stuff, but it certainly is exercising the compiler and language.

Abstract Syntax Tree structure for variable definition
I prefer to make my AST nodes fairly rich, and let them do the brunt of the work themselves. Instead of the 5 lines of code above, the assignment statement node in Ecstasy is over 1000 LOC. But it handles everything from initial validation through the MLIR emission.
No, not that specific project. It's our own Mid Level Intermediate Representation (or Mid Level Intermediate Language), aka MLIR/MLIL. Here's a snapshot of the operators.

January 2022 monthly "What are you working on?" thread
I am working some again on my Ada-like language bluebird. I am making another attempt to use MLIR as an intermediate IR between the AST and LLVM IR (I made a brief attempt a few months ago just to look into it).
-
September 2021 monthly "What are you working on?" thread
I fworked some more towards adding pointers on my Ada-like programming language bluebird. I've finished adding pointer types and variables (as well as the operators for dereferencing/getting the address of objects), but I still need to add the ability to dereference and assign.
-
July 2021 monthly "What are you working on?" thread
I started to experiment with using MLIR to write a high-level IR for my language bluebird, which will hopefully reduce the work of implementing features I want to add such as generics and ranges, as well as allowing me to eventually write some optimizations. I am also considering rewriting my AST as an MLIR dialect, since MLIR provides a bunch of type-checking/error printing/support infrastructure.
-
June 2021 monthly "What are you working on?" thread
I continued implementing support for references (a restricted form of pointers) in my Ada-like language bluebird. I also am working on adding a cleanup pass between my parser/typechecker to handle stuff like type resolution of literals and constant folding.
-
May 2021 monthly "What are you working on?" thread
I didn’t add too many new features to my Ada-like language bluebird this month because of lots of projects/school stuff.
-
March 2021 monthly "What are you working on?" thread
I made some more progress on bluebird, my Ada-like language.
-
February 2021 monthly "What are you working on?" thread
I continued to make progress on the compiler for my Ada-inspired language bluebird. I will have less time to spend on it as classes began earlier last month, but I still hope to continue working on it. Things are getting to the point where adding a new feature isn’t as difficult as it was when doing so often meant writing the supporting code from nothing.
