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.

What's the best way to get my language stress tested?
You can use the free GitHub runners to execute regression tests on Linux, Windows, and Mac. I recommend testing with 32bit compilation as well as 64bit- it has a way of smoking out bugs. You could take a look at the GitHub actions on my Forscape repo in the .github folder, although it's probably not the most idiomatic runner scripting, but it is a C++ project like yours.

Word Processor from scratch WYSIWYG with Web Assembly
When I was developing a typesetting text editor for Forscape, I struggled to get traction until stumbling on the following plan: 1) Implement the document data structure and get it rendering to the screen 2) Support non-mutating interactions, such as clicking to move the text cursor, selecting, copying, etcetera 3) Support mutating interactions, such as keyboard input, deleting, and pasting. You'll probably use the Command pattern to support undo/redo of mutations

Which phases/stages does your programming language use?
The project is Forscape, although the language part is made a bit complicated because a goal of the project is creating an editor that supports typeset code with IDE interaction

[Weekly] What is everybody working on? Share your progress, discoveries, tips and tricks!
Finally adding multi-file support to Forscape. The frontend UI aspects are completed and I'm quite happy with the result. The app is Unicode heavy and QString's UTF-16 encoding is an annoyance; I would much prefer if Qt relied on std::string even. But the signal/slot mechanism lets you achieve some complicated behaviour with minimal complexity, and Qt looks great.

Build Qt Project w/GitHub Actions
Here's an example from a project. The first step installs Qt, the second step clones my repo on the runner, then a bit more setup with Conan, then building and running.

C++ Show and Tell - November 2022
I've been working on the Key CAS project (Imgur Screenshot), CAS being an acronym for Computer Algebra System, and "Key" a judiciously chosen title. This was my third time attempting CAS- this iteration was a huge improvement, but I still find it to be a damn hard problem. The GUI comes from the open source project Forscape, a scientific computing environment written in C++.

What Operators Do You WISH Programming Languages Had? [Discussion]
It gets fun when you go beyond flat symbols and start supporting 2D notation, like fractions and matrices. Probably not worth the hassle for most things, but I think it makes matrix expressions more compact with better readability.

What Are You Working On? August 29, 2022
I've been working on a mathematical programming language, Forscape. Currently it's entirely numerical, but I'm building a CAS separately which I hope to use in the language.

Forscape: what features are in your ideal scientific language?
Forscape is a scientific computing language in development. It supports first-class matrices and common matrix operations. The language reached a milestone when it achieved similar performance to other prominent scientific langs on a computationally involved numerical problem from my graduate school years. At this point, I am unsure where the development should go next and I would appreciate advice. What do you find missing in scientific computing languages? What are essential features that you need/enjoy?

The Neat Programming Language
I think lobster does this.
"Compile time reference counting / lifetime analysis / borrow checker."[1]
"Reference Counting with cycle detection at exit, 95% of reference count ops removed at compile time thanks to lifetime analysis."[1]

Why does Rust need humans to tell it how long a variable’s lifetime is?
There is another language, Lobster, that uses lifetime analysis like Rust, but IIUC infers lifetimes completely automatically. It looks like the idea is still experimental - I'm interested to see how it goes.
-
What are some must have built-in modules in your opinion/experience?
I think the ability to open a window and do graphical stuff is actually pretty underrated in core language functionality. There's a few game-oriented programming languages like Lobster that put windowing and graphics in the core language functionality, and I think it's pretty neat. The biggest downside is that it's a lot to bite off, because you'll probably want to have standardized API functionality for a whole host of things like font rendering, image loading, etc.

Minetest: An open source voxel game engine
The actual game itself, yes. Based on this open source project though which provides the language its written in and core engine tech: https://github.com/aardappel/lobster
-
Plane - FOSS and self-hosted JIRA replacement. This new project has been useful for many folks, sharing it here too.
I'm keeping an eye on Lobster though. It fixes most of Python's problems. It's way faster, has proper static typing, the import system is sane, etc.
-
Using a borrow checker to track mutable refs in a GCed FP language?
Lobster (https://strlen.com/lobster/) appears to at least do lifetime analysis to reduce refcounting. I'm not sure about automatic interior mutability. I feel like there's a keyword here that can help find other compilers with similar features.
-
What would make you try a new language?
Also, can I introduce you to https://strlen.com/lobster/, a garbage collected language made for game development by (and primarily for) the one and only Wouter "aardappel" van Oortmerssen?
-
In a custom typed imperative programming language, what should the compiler do next, after resolving variable references?
I would like to make it work to some degree like Rust with a borrow checker, and have optional static typing (with type inference wherever it can). Other sources of inspiration, lobster lang, and dart. It is going to (eventually...) compile to several places like dart (browser, iOS, android, linux, etc.). After I've created the AST, I've gone straight to code generation, because that's the easy part IME. But now have to insert the "middle" and do typechecking/borrowchecking/inference/other checking. This is for an imperative-style language.
-
Features you've removed from your lang? Why did you put them in, why did you take them out?
Over the ~12 years of Lobster (https://strlen.com/lobster/) 's existence, features that were removed (in this order): * Lexical scoping. * Icon style backtracking. * Small-talk like syntax. * Dynamic Typing. * Multimethods. * Frame based state (like FRP). * Co-routines.
