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 difficult would it be to make a c++ compiler
Sean Baxter created a front end c++ compiler by himself, using llvm for the back end and the gcc or clang stl. I think it took him a couple of years. https://www.circle-lang.org/. Before this happened I heard a couple of different people claiming that there would never be a totally new compiler as it was too much work.

Toward a TypeScript for C++"
The real Typescript for C++ is Circle.
https://www.circle-lang.org/
Just like Typescript to JavaScript, the syntax is an evolution of what already exists, not a completely different syntax.

Circle Evolves C++ [video]
Context: https://github.com/seanbaxter/circle/blob/master/new-circle/...
Note that Circle is not an F/OSS compiler as someone pointed out before. This however doesn't make Circle less relevant, because it is actually a testament to show that C++ could have been much better without the claimed breakage. If Circle does provide a number of desirable features and its compiler can be built by a single person, then why shouldn't the committee do the same?

My (Herb Sutter's) C++ Now 2023 talk is online: “A TypeScript for C++”
From all wannabe C++ replacements candidates, the only language that is really a TypeScript for C++, is Circle.
For whatever reason, Herb Sutter decided to ignore this language on the presentation.
https://www.circle-lang.org/
This is the only one with the syntax based on C++, incrementally changing the features via #pragma settings.

Making C++ Safe Without Borrow Checking, Reference Counting, or Tracing GC
The second someone makes a successor language that seamlessly/directly interops with C++ _AND_ has the level of build/IDE tooling that C++/Rust have, I'm on board.
The closest thing right now is Sean Baxter's "Circle" compiler in "Carbon" mode IMO:
https://github.com/seanbaxter/circle/blob/master/new-circle/...
Unfortunately, Circle is closed-source and there's no LSP or other tooling to make the authoring experience nice.
- Circle-lang: A feasible, simple, and immediate way for C++ to break out of the rut it's been in. Surprised more people aren't talking about it.

Recurrence-expression is a programmable superset of fold-expression
I read through the whole of https://github.com/seanbaxter/circle/blob/master/new-circle/README.md and man, I'm drooling. Awesome work, kudos.

Dropping support for old C++ standards
Have a look at Circle from Sean Baxter [0]. It's pretty impressive.

Trying out Reflection TS experimental
I guess I'm confused which compiler to use. Is this by lock3 the "demo" implementation which is superseded by clang 15.0-reflection (godbolt says that's the compiler used). I'm using clang for now
-
Experimental Clang implementation of TS Reflection is now available.
Is it related to the "meta" branch or a completely independent work ? (https://github.com/lock3/meta/wiki)
-
Adding reflection to an existing codebase
then there's no pure C++ solution, you either have to use alternative compilers such as https://github.com/lock3/meta/wiki or Circle, or use an external reflection system such as Qt's moc
