Lua-RTOS-ESP32 VS terra

Lua-RTOS: a real-time operating system for ESP32\ (21 comments)

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.

Chapel has at least several full-time developers at Cray/HPE and (I think) the US national labs, and has had some for almost two decades. That's much more than $100k.

Chapel is also just one of many other projects broadly interested in developing new programming languages for "high performance" programming. Out of that large field, Chapel is not especially related to the specific ideas or design goals of Mojo. Much more related are things like Codon (https://exaloop.io), and the metaprogramming models in Terra (https://terralang.org), Nim (https://nim-lang.org), and Zig (https://ziglang.org).

But Chapel is great! It has a lot of good ideas, especially for distributed-memory programming, which is its historical focus. It is more related to Legion (https://legion.stanford.edu, https://regent-lang.org), parallel & distributed Fortran, ZPL, etc.

Terra is the language you're looking for: https://terralang.org/

Wow, amazing stuff. I love Lua, it was how I learned programming as a kid. Coincidently from the same world as the author. Open Tibia.

The author made a custom client (https://github.com/edubart/otclient) for the game that is still very much in active use by thousands of players. He's a very skilled developer.

Great to see AOT typed Lua, I know of the other solutions: Luau, Teal, TypeScriptToLua, Terra, etc., but this one is my favorite so far.

Love the simple compilation to C (and WASM support via Emscripten). Though Terra's JIT is enticing and good replacement for LuaJIT, this is for embedded systems, it's a good replacement for Lua PUC-Rio.

Terra is a language that can also do that, and uses Lua as the metaprogramming language. Types are just Lua values.

But unfortunately, there's a lot of work left kind of half-baked so using the language is a pain... if someone invested a lot of time to make Terra work properly and added some tooling around it, wrote proper docs and so on, it would be a really interesting language.

I have been playing with Terra lately, which is a statically compiled version of Lua which is itself metaprogrammed in Lua.. Terra happens to have completely seamless interop with C, so to call C is as trivial as this:
