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.

Nitter (Twitter front end) is working again
The frontend uses Karax, which is my favorite frontend/SPA library. It is an absolute joy to use, even if it's a bit rough around the edges.

I learned 7 programming languages so you don't have to
I have used Nim for personal projects for 6 years now and it continues to surprise me on how well versed it is for many problem domains. I am fond of it's SPA framework, karax https://github.com/karaxnim/karax for which I wrote a translation utility https://github.com/nim-lang-cn/html2karax Latest Nimv2 release candidate has improved in the ergonomics and syntax that affect compilation to js, so I was able to cleanup my webapp's code to be less verbose. On GPU programming there has been a few projects that touch GPU programming, most notably https://github.com/treeform/shady

Web apps in pure Python.
And it's present not only in Python but in other languages as well. Check for example https://github.com/karaxnim/karax - I don't know why people would want to hide all of their HTML in Python/whatever language. Then limit their ability to script and style it in one way or another.

A Cost Model for Nim
> the real killer feature to me is the javascript target
Agree, this is amazing because you can share code and data structures between front and backend (for example: https://github.com/karaxnim/karax).
Also, it's really nice having high level stuff like metaprogramming and static typing spanning both targets. Things like reading a spec file and generating statically checked APIs for server/client is straightforward, which opens up a lot of possibilities.

Will Zig interop with JavaScript/Web at all?
E.g. Nim focuses on enabling what it calls "single page web apps": https://github.com/karaxnim/karax.

How to use JS to make a front end
I recommend you to take a look at Karax. It's a front-end framework for Nim that can compile to regular JavaScript. If you want to know how to use it with a webserver, Joker is a good example. With the Joker config, all of the compiled .js files land in /public/views, where you can take a look at them. But keep in mind that the JS that Nim produces is often rather cumbersome and hundreds of lines long, even if it's just a simple program.

I learned 7 programming languages so you don't have to
Also on the game development front, I maintain a raylib wrapper https://github.com/planetis-m/naylib As long utilities like c2nim https://github.com/nim-lang/c2nim exist, it's trivial to create bindings of C/C++ libraries. One thing I want to experiment more is making it more automatic by writing a callback exposed by c2nim that transform the generated code using Nim's AST. But regardless in that project I was able to write safe language abstractions on top of the bindings that provide a more native experience. It has scope-based memory management, generics and ... function overloading.

The way integrate Rust into Nim
Rust also has a library called safer_ffi that makes FFI easier, and I tried to use that, but the library seems to be immature, and I could not get arguments in Rust functions. If this library can be used properly, it will be possible to output C header files from Rust functions and automatically generate Nim interface functions from C header files using c2nim. We look forward to further development of this feature.
-
Checked C
Well I'm 99.5% certain at least. Even now I'm uncertain of the C syntax. And I've not been bold enough to test 3rd order C function pointers. I figure that's probably C code you don't wanna touch if possible.
https://github.com/nim-lang/c2nim/blob/11f2c5363dfe7e8c7c8ce...
The other annoying one is that "signed" and "unsigned" are basically adjectives, but "long" can be both a type and a modifier. So it's difficult to parse unless you're the target C compiler. Technically you can, but you have to use backtracking.

Nim -- a modern "glue" language like Python
c2nim is a tool to translate ANSI C code to Nim. The output is human-readable Nim code that is meant to be tweaked by hand after the translation process. If you are tired of wrapping C library, you can try futhark which supports "simply import C header files directly into Nim". Similar to futhark, cinterop allows one to interop with C/C++ code without having to create wrappers. nimLUA is a glue code generator to bind Nim and Lua together using Nim's powerful macro. nimpy and nimporter is a bridge between Nim and Python. rnim is a bridge between R and Nim. nimjl is a bridge between Nim and Julia! Last but not least, genny generates a shared library and bindings for many languages such as Python, Node.js, C.

Genny – Generate Nim library bindings for many languages
Now if only a full binding generator for C and C++ headers to Nim was done, the language would really be cooking!
"What do you mean, Nim has two of these already?"
Yeah, I know, and -- not to hurt anyone's feelings -- but: they kind of suck. And there's no way I see them able to be extended to do the job fully, based on the way they're currently built.
Those are some bold claims to make!
So before I get stoned to death (no offense to the authors, I am grateful that they exist and have used them both) let me attempt an explanation and back up these statements.

To start off, the two tools available are "c2nim" and "nimterop". c2nim is a Nim official library, while nimterop is a community library.

ffipf - quickly jump to file in a project with a native module
Yes. Nim compiles to C and has a lot of features for interacting with C code. You can easily call C routines from Nim and Nim functions from C. There's a bit of a ceremony you need to go through, but most of it can be automated with c2nim tool: https://github.com/nim-lang/c2nim
