is Teal strongly or weakly typed? Static or Dynamic?

Title says it all

"Statically vs dynamically" is a more well-defined distinction, that is agreed upon in academia. Teal is statically typed; Lua is dynamically typed.

"Strongly vs weakly" is often used to mean the same as the above, but sometimes it is used to mean that you can map memory to different types. In the latter sense, both are strongly typed, in the sense that you can't really map a memory location to a different type (cast in the C sense); in Teal you have a cast, but attempting to use a value as the wrong type will cause a runtime error.

Here is what I think is an EXCELLENT article on what we spoke about earlier:
https://ericlippert.com/2012/10/15/is-c-a-strongly-typed-or-a-weakly-typed-language/

Don't worry if you didn't succeed at Rust at first. It is not the easiest language to grasp :) Slow
and steady wins that race.

I LOVE RUST. Preaching to the choir. When you're playing an RPG you can't just skip to the last boss; you have to get all the crystals first. I can't wait until I'm proficient enough to truly understand that language.

compiling to luajit doesn't really help for it running in the browser. (In fact, it might even hurt it compared to regular lua?). Compiling directly to WASM would make it A LOT easier to run in the browser. However, as a language like you describe would most likely require quite a big runtime (the GC for example) this also becomes less ideal. (Last time I checked, a simple hello world from some Go lang to wasm project took multiple seconds to load, presumably because Go needs a runtime that needs to get loaded as well.)

Good to know, thank you for the clarification!

As far as I can tell, the language I'm describing is Teal, I just didn't understand that when I originally posted. This is kind of hard to explain, but I'm going to draw out kind of what I was thinking. I will upload a picture in a little while.

Thank you guys again, I try not to ask too many questions (I think the arch guys scared me haha). This might be the single greatest conversation I've ever had though..

teal doesn't compile to machine code though?

Ask away, but.. maybe on gitter instead of this thread? 😅

From my understanding Teal compiles to Lua which does compile into machine code? I drew a picture to help conceptualize this lol.

GOOD TO KNOW. For what it's worth the society in reality took me a while to figure out too. I suppose next time I have a question I will ask there (just now learning of its existence so thank you)

lua gets interpreted by a VM

mlua/rlua (assuming you refer to https://docs.rs/mlua/latest/mlua/ ) is just bindings for Rust to lua VM. It allows running lua code because not because it compiles it, but because it contains the VM and instructs that to run it.

There are a couple of projects to get lua working on the web, but those work by compiling the lua vm to WASM or JS, and run the scripts that way. (this is also how C# runs on WASM btw)

It could be that there is a project out there that compiles lua to machine code, and LuaJIT gets close at it JIT's it but that still has a VM to my knowledge and only does this compilation for functions that it thinks are worth it and does this during runtime. Mlua and Rlua are however not these compilers. They just allow Rust code to interact with various Lua vm's.

There is actually a language that is similar to Teal (Lua with types) and compiles down to C: https://nelua.io

In this space you can also check out Titan / Pallene and Terra.
