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.

Ask HN: LLVM vs. C
So how does the LLVM C backend work then?
https://github.com/JuliaHubOSS/llvm-cbe
-
rust to c complication?
One alternative worth mentioning, though, would be the LLVM C Backend maintained by the Julia community.
-
Programming language that compiles to clean C89 or C99?
If you drop "easily" and "human" (/s) from your requirements list, then the C backend for LLVM might work. Then you can choose any programming language you want that has LLVM 10-compatible frontend.
-
Easy way to convert a C++ library into straight C ?
If you really must have something that compiles in C (e.g. for a platform where you only have a C compiler) there's an LLVM backend that outputs C code: https://github.com/JuliaComputingOSS/llvm-cbe
- Snowman native code to C/C++ decompiler for x86/x86_64/ARM

Can Rust do every low level stuff C/C++ do?
You can convert llvm bitcode to C and then use C compiler, there is such project https://github.com/JuliaComputingOSS/llvm-cbe .

lipstick: a Rust-like syntax frontend for C
I'm really surprised that the LLVM C backends have continually been resurrected then abandoned over the years. It's a good solution to this sort of thing and would enable a lot of cool stuff like Rust to weird embedded platforms. The most recent one is the Julia backend: https://github.com/JuliaComputingOSS/llvm-cbe

Show HN: prometeo – a Python-to-C transpiler for high-performance computing
Well IMO it can definitely be rewritten in Julia, and to an easier degree than python since Julia allows hooking into the compiler pipeline at many areas of the stack. It's lispy an built from the ground up for codegen, with libraries like (https://github.com/JuliaSymbolics/Metatheory.jl) that provide high level pattern matching with e-graphs. The question is whether it's worth your time to learn Julia to do so.
You could also do it at the LLVM level: https://github.com/JuliaComputingOSS/llvm-cbe
For interesting takes on that, you can see https://github.com/JuliaLinearAlgebra/Octavian.jl which relies on loopvectorization.jl to do transforms on Julia AST beyond what LLVM does. Because of that, Octavian.jl beats openblas on many linalg benchmarks

Writing a SQLite clone from scratch in C
You can try your luck with the "resurrected" C backend: https://github.com/JuliaComputingOSS/llvm-cbe
I don't understand why I see so many requests for LLVM-based languages to change around their backend or IR, that seems to be a huge amount of work for comparatively little benefit. The correct thing to do there is to just add support for those to LLVM.

Did we lose our way in making efficient software? – ~30 MB doc file vs. browser
It's interesting: minimal software is out there, but folks don't tend to choose it. I spend a fair amount of time thinking about how to be conservative in my dependencies, and this encourages a lightweight stack that tends to perform pretty well. These days, I'm favoring tools like Lua, SQLite, Fennel[0], Althttpd[1], Fossil[2], and the Mako Server[3] and find that great, lightweight, stable, efficient software is to be had, for free, but you have to go a bit off the beaten path. This isn't stuff you hear about on Stack Overflow.
In terms of frontend, which the post focuses on (Google Docs and a 30MB doc), I guess I'm conflicted. While I tend to favor native apps + web pages, I'm also a daily Tiddlywiki user, and I really think web apps have their place (heck, one idea I'm working on is a lightweight local server that lets you run web apps like Tiddlywiki). But without a doubt, Tiddlywiki is more resource intensive than Emacs (my go-to for notetaking when I'm not on TW). My tab for a 6MB Tiddlywiki file uses 155MB of RAM, and my (heavily customized, dozens of open buffers) Emacs session uses 88MB. So I do think the author has a good point.

Pluto, a Modern Lua Dialect
Eh it's not just luajit and luajit didn't create that problem either. It's a symptom of lua actually succeeding at its design goal of being easily embedded as an extension language. A significant number of incompatible runtimes are more popular than the most recent puc lua, including I believe the older official lua 5.2 released in 2011.
I've done a fair bit of professional lua development and I don't think I've ever written standalone up-to-date puc lua except maybe for some tooling & scripts. It's such a small language and used in such a way that the runtime, distribution method, and available APIs have much more impact on your use (and compatibility) than the version.
Virtually everyone shipping a lua environment is also shipping changes to it that make it a unique target, if only extensions to the standard library. This is why I think syntax layer-only approach like fennel's is the correct choice for improving on lua. It mirrors lua's runtime semantics exactly, and allows you to access the implementation peculiars on their own terms and so can just be run on time of any lua system.

LÖVE: a framework to make 2D games in Lua
Just learned about https://fennel-lang.org/ , could have probably used that as well to avoid Lua.

The Bipolar Lisp Programmer
> I’m positive that there is a Lispy language out there (actually in existence, or the aether) that is appropriate for embedded work, but the constraints of the target make it difficult to envision.
Perhaps Fennel* fits the bill?

The Future of the Vim Project
I've also seen neovim plugins written in fennel [0], so if you want something lispy, that's possible now.

TimL: Clojure-like Lisp dialect that runs on and compiles down to Vimscript
Something similar: Fennel (https://fennel-lang.org/) is a lisp that compiles into Lua, which nvim can use as plugins, so you can write nvim plugins in a lisp. Aniseed (https://github.com/Olical/aniseed) makes this really easy.

Announcing automation-service: write and schedule home automation scripts in Lua
If you want a more FP language on the Lua runtime, you might be interested in Fennel. I wrote a post about adding Fennel compiler to a hslua interpreter a while back, which might be useful for you.
