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.

Static Type Safety with Variadic Functions: an Idea and a Question
For further reading, there's a paper on arity generic programming and some solutions using dependent typing in Agda.
-
When do you find it better to use non-ASCII identifiers?
In Rust I have never seen it. However, in Agda it's a convention, and the code looks beautifully https://github.com/agda/agda-stdlib/blob/master/src/Algebra/Lattice/Structures.agda
-
Should programming languages switch to special characters (gliphs) for it's code?
Agda is a good example, as it allows you to define arbitrary Unicode-based operators and names: https://github.com/agda/agda-stdlib/blob/master/src/Data/Product.agda
-
Separating the type and value namespaces?
Most of the times you want the first three arguments to be passed implicitly, not just the first. And the syntax for passing arguments implicitly is the same for the type argument A and the term arguments n and m. (For Agda, see e.g. l.49 here: https://github.com/agda/agda-stdlib/blob/master/src/Data/Star/Vec.agda)

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?
