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.

Cpp2 and cppfront – An experimental 'C++ syntax 2' and its first compiler
The evolution of C++ has been a multi-decade history of dealing with difficult reality.
I have great hope that Herb can create with his cppfront project “The Very Best of C++” to carry that tremendous legacy forward.
If I was to throw my hat into a “C++ successor”, it would be https://www.hylo-lang.org/ with its “all the safeties” and “tell you when you’re doing it sub-optimal” approach.

Borrow Checking Hylo [video]
Paper: https://2023.splashcon.org/details/iwaco-2023-papers/5/Borro...
> Hylo is a language for high-level systems programming that promises safety without loss of efficiency. It is based on mutable value semantics, a discipline that emphasizes the independence of values to support local reasoning. The result—in contrast with approaches based on sophisticated aliasing restrictions—is an efficient, expressive language with a simple type system and no need for lifetime annotations.
> Safety guarantees in Hylo programs are verified by an abstract interpreter processing an intermediate representation, Hylo IR, that models lifetime properties with ghost instructions. Further, lifetime constraints are used to eliminate unnecessary memory allocations predictably.

Why do lifetimes need to be leaky?
A model without lifetimes is also being explored in other languages, e.g. in Hylo. It sacrifices expressiveness, but on the other hand you don't have to deal with explicit lifetimes!

D Programming Language
Why go through all the trouble when you can do this: https://www.hylo-lang.org/ and not spend a second thinking of lifetimes? No, copies will not be issued unless necessary.
Or why not keep exploring this idea as well? More research-oriented than the first one right now, though, so take it with a grain of salt: https://vale.dev/

I've heard that "Rust's borrow checker is necessary to ensure memory safety without a GC" usually also implying it's the only way, but I've done the same without the borrow checker. Am I just clueless/confused?
Get rid of references at the cost of some expressivity (see Hylo, formerly Val)

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.
