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.

NIR: Nim Intermediate Representation
> What does this mean? There's a runtime VM or compile time VM?
Compile time VM. It's used to run macros / templates / concepts. You can also run most code at compile time in a `static` block except for stuff that needs C calls. You can also compile the VM into a program and use it as a runtime VM (see https://github.com/beef331/nimscripter) which I do in my GUI lib. NIR should enable the compile time VM to run faster too, and possibly use JIT'ed code.

Checkout Nim! It does much of what you describe and its great. The core language is fairly small (not quite lua simple but probably ML comparable). It compiles fast enough that a Nim repl like `inim` is useable to check features and for basic maths, though it requires a C compiler, but TCC [4] works perfectly. Essentially Nim + tcc is pretty close to your description, IMHO. Though I'm not sure TCC supports non-x86 targets.
I've never used it but Nim does support some hot reloading as well [3]. It also has a real VM if you want to run user scripts and has a nice library for it [1]. Its not quite Lua flexible but for a generally compiled language its impressive.
Recently I made a wrapper to embed access to the Nim compilers macros at runtime [2]. It took 3-4 hours probably and still compiles in 10s of seconds despite building in a fair bit of the compiler! It was useful for making a code generator for a serializer format. Though I'm not sure its small enough to live on even beefy m4/m7 microcontrollers. Though I'm tempted to try.

Show HN: Nimwave – build TUIs for the terminal, web, and desktop
https://github.com/elcritch/cdecl/blob/ee3b06f52e666b2a854eb...
I also found that `useState` pattern from React with the variant library a handy pattern: https://github.com/yglukhov/variant and it’s pretty simple to do if you already have a context object: https://github.com/elcritch/fidgetty/blob/f65876af34797f308b...
Sorry for the link spamming, I just find the overlap of UI state management without OO interesting!
What are some alternatives?
incbin - Include binary files in C/C++
nimwave - TUIs for the terminal, desktop, and web
pyker - Python tool to convert files from a directory tree into a C header file.
pl_mpeg - Single file C library for decoding MPEG1 Video and MP2 Audio
fidgetty - Widget library built on Fidget written in pure Nim and OpenGL rendered
execfs - Proof of concept userspace filesystem that executes filenames as shell commands and makes the result accessible though reading the file.
vim_cubed - Vim rendered on a cube for no reason
langserver - The Nim language server implementation (based on nimsuggest)
variant - Variant type and type matching for Nim
nim - Mono - Nim Web Framework
