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 feature would you like to see in C++26?
static reflection and pattern-matching, as everyone is saying, but I'd also like to see a garbage-collecting smart-pointer in the standard library similar in design to Herb Sutter's deferred_ptr

Rust went from side project to world’s fastest growing language
There are definitely fringe edge cases where C++ can do things that Rust simply cannot, currently.
I'm thinking of things like Herb Sutter's deferred_heap (https://github.com/hsutter/gcpp) that give you GC-like abstraction. It's pretty cool that this is possible to write in vanilla C++ with decent ergonomics. I tried to make something similar awhile back and hit a wall in terms of making something that would be pleasant to use.
Rust has several on-going experiments with making a nice GC, along with good support for arenas. (If you can use arenas, they're great.)
-
Now the C++ removed garbage collector support, is it still possible the have a global garbage collector in a C++ application?
Check out this library: https://github.com/hsutter/gcpp

tracked_ptr - when shared_ptr is not enough
Hm, yeah, that's pretty unclear. My understanding is based off the link to Herb's proposal in the OP, which I understand this to be an evolution of.
-
What do you think will be the future direction for C++ evolution?
Re garbage collection: My understanding was that the standard API was intended for interop with managed languages, not for pure C++ code to use, although I could be mistaken. I don't think garbage collection is entirely a lost cause, for instance Herb Sutter's work, which I think he wants to integrate in Cppfront, would be a great way to do it. Imo, his garbage collection ([1] [2]) could be much better than D or Nim, because it has easily controllable performance characteristics. You don't pay for it if you won't use it, and it's unlikely that libraries you pull in would need it, which is imo what makes programming without the "optional" GC in D and Nim difficult.
- Any guesses as to how C++ will turn out w.r.t. garbage collection?

Why do people want a garbage collector in C++?

New "Java to C++" code converter tool for beginners
Something like gcpp would be quite nice. That and a intelligent scope detector could make use of isolated and local GC when it detects that some objects stays together and have similar lifetime.

Rust to .NET compiler – Progress update
> There are online Rust compilers and interpreters already if you just want to rapid prototype and develop ideas in Rust
You are responding to one of the key developers of Rust early on[1], who's been working with the language for 14 years at that point.
[1] https://github.com/rust-lang/rust/graphs/contributors?from=2... and he's still #16 in commits overall today, despite almost no activity on the rust compiler since 2014.

Create a Custom GitHub Action in Rust
If you haven't dipped your touch-typing fingers into Rust yet, you really owe it to yourself. Rust is a modern programming language with features that make it suitable not only for systems programming -- its original purpose, but just about any other environment, too; there are frameworks that let your build web services, web applications including user interfaces, software for embedded devices, machine learning solutions, and of course, command-line tools. Since a custom GitHub Action is essentially a command-line tool that interacts with the system through files and environment variables, Rust is perfectly suited for that as well.

Why Does Windows Use Backslash as Path Separator?
Here's an example of someone citing a disagreement between CRT and shell32:
https://github.com/rust-lang/rust/issues/44650
This in addition to the Rust CVE mentioned elsewhere in the thread which was rooted in this issue:
https://blog.rust-lang.org/2024/04/09/cve-2024-24576.html
Here are some quick programs to test contrasting approaches. I don't have examples of inputs where they parse differently on hand right now, but I know they exist. This was also a problem that was frequently discussed internally when I worked at MSFT.

I hate Rust (programming language)
> instead of choosing a certain numbered version of the random library (if I remember correctly) I let cargo download the latest version which had a completely different API.
Yeah, they didn't follow the instructions and got burned. I still think that multiple things went wrong simultaneously for that experience. I wonder if more prevalent uses of `#[doc(alias = "name")]` being leveraged by https://github.com/rust-lang/rust/pull/120730 (which now that I check only accounts for methods and not functions, I should get on that!) so that when changing APIs around people at least get a slightly better experience.

Show HN: Fancy-ANSI – Small JavaScript library for converting ANSI to HTML
Recently did something similar in Rust but for generating SVGs. We've adopted it for snapshot testing of cargo and rustc's output. Don't have a good PR handy for showing Github's rendering of changes in the SVG (text, side-by-side, swiping) but https://github.com/rust-lang/rust/pull/121877/files has newly added SVGs.
To see what is supported, see the screenshot in the docs: https://docs.rs/anstyle-svg/latest/anstyle_svg/

Upgrading Hundreds of Kubernetes Clusters
We strongly believe in Rust as a powerful language for building production-grade software, especially for systems like ours that run alongside Kubernetes.
What are some alternatives?
sgcl - Smart Garbage Collection Library for C++
carbon-lang - Carbon Language's main repository: documents, design, implementation, and related tools. (NOTE: Carbon Language is experimental; see README)
graph_ptr - A smart ptr implementation that can handle cycles, similar to herb sutter's deferred_ptr.
