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.

Charm 0.4: a different kind of functional language
Charm is a language where Functional-Core/Imperative-Shell is the language paradigm and not just something you can choose to do in Python or Ruby or PHP or JS or your favorite lightweight dynamic language. Because of the sort of use-cases that this implies, it didn't seem suitable to write another Lisp or another ML, so I got to do some completely blank-slate design. This gives us Charm, a functional language which has no pattern-matching, no currying, no monads, no macros, no homoiconicity, nor a mathematically interesting type system — but which does have purity, referential transparency, immutability, multiple dispatch, a touch of lazy evaluation, REPL-oriented development, hotcoding, microservices … and SQL interop because everyone's going to want that.

Charm 0.4: now with ... stability. And reasons why you should care about it.
I think it's fair to call this a language announcement because although I've been posting here about this project for a loooong time, I've finally gotten to what I'm going to call a "working prototype" as defined here. Charm has a complete core language, it has libraries and tooling, it has some new and awesome features of its own. So … welcome to Charm 0.4! Installation instructions are here. It has a language tutorial/manual/wiki, besides lots of other documentation; people who just want to dive straight in could look at the tutorial Writing an Adventure Game in Charm.

Programming in Plain Language?
In my own language there is some syntactic flexibility but the only thing that describe pretty table could mean would be the second of the possibilities above; the first would be expressed by describe prettyTable and the third by describe PRETTY, table. This makes it more readable from the point of view of a coder, and who else is going to want to read it, my mom?

Embedding other languages in Charm: a draft
I've been trying to think of a way of doing this which is simple and consistent and which can be extended by other people, so if someone wanted to embed e.g. Prolog in Charm they could do it without any help from me.

Lazy Let: A Cheap Way and Easy Way to Add Lazyness
Charm does this for declaration of local constants in functions (there are no local variables in functions). So for example if you wanted to write the Collatz function this way (which you wouldn't, it's just a minimal example) then you could do so without worrying about a computational explosion:

I guess it's time for me to put aside my exploration of Charm and set up a collaboration with my son the lyricist.

Global and local variables, a choice of evils
In fact that's how a lot of Charm programs end up getting written, because you want to pass a whole bundle of stuff to the functions. For example.

What the imperative shell of an Functional Core/Imperative Shell language looks like
No, it's "shell" as in "shell of the code". The idea is that the imperative bits of the language, the bits that do the mutation of state and the IO, can can call lovely pure referentially transparent functions. But functions can't call commands (otherwise by definition they wouldn't be pure). So all your imperative-ness is reduced to about 1% of your code which lives right at the top of your call stack --- the "imperative shell" of your code. See [here](https://github.com/tim-hardcastle/Charm/blob/main/examples/adv.ch) for an example. The "imperative shell" is the main function --- all 13 lines of it --- and everything everywhere else is pure and immutable.

What are some cool things you've built using your own language?
I'm not sure what counts as cool. It's just dogfooding at the moment. I did a bunch of other languages (only the BASIC and the Forth are up to date with the current version of the language I think), and I did a tiny adventure game (and used it as the basis for a tutorial).

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/
