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.

platformio integration with neovim?
I forgot to say that I use this llvm build. Just download the release and point the clangd server to it.

LLVM 16.0.0 Release
Xtensa support (esp32). Will be interesting how this will be for Rust and Zig support for esp32

How do I program an ESP32 S3 in Rust using podman from WSL?
Hopefully, in the future the installation will be simpler, as we are trying to upstream our LLVM changes (first 10 patches are already accepted!), and once we manage to upstream LLVM changes we will proceed with upstreaming our Rust fork changes.

Using Vim as an editor for ESP-IDF
The main discussion can be led back to this GitHub issue and this comment; fortunately, we don't need to build espressif's llvm fork anymore as they supply the clangd (this is the language server we need) and you can find the zip here. I'll briefly list down the steps required to set up vim with clangd to take advantage of clangd's features (auto-completion, linting, code refactoring ...)

The more I use other MCUs the more I like the ESP32
In my case, it's pretty annoying that the Xtensa platform doesn't have official LLVM support. It's in progress but going very slowly.

Have you ever started a project in Rust but switched to a different language? If so, why?

Are there situations where it's better to use C++?
Xtensa. They've got a fork of LLVM that supports it that they're working toward getting upstreamed. The community has a fork of rustc that uses it (and a quickstart crate) while we wait for it to get upstreamed.

Rust and GCC, two different ways
https://github.com/espressif/llvm-project/issues/4 is a good example why updating llvm isn't easy and takes a lot of time.

uLisp
Just to clarify - Gambit, Chicken, and Carp all compile to portable C.
I hadn't realized LLVM mainline doesn't support Xtensa. I'm surprised.
D does support Xtensa via LDC (https://forum.dlang.org/thread/[email protected]...). It looks like GDC also nearly supports it, requiring only a minor patch at present.
A functioning LLVM backend does exist (https://github.com/espressif/llvm-project/issues/4) and might be making very slow progress towards being merged. A quick search shows that it works for Rust. I suspect (but don't know) that it might work for Terra as well.
There's also the LLVM C backend (https://github.com/JuliaComputingOSS/llvm-cbe) but I've no idea how efficient such an approach is when applied to real world embedded tasks.

uLisp
There's also Lua RTOS[1] plus Fennel[2]. Lua is easy to embed, but I find the syntax pretty bad, and Fennel fixes most of it for me.
