It hasn’t been used for quite a bit, it’s LuaU instead. The keywords, syntax, etc. is almost exactly that of Lua.
LuaU serves as a “better Lua.”
What language do you use?
Luau
What’s that?
Its a derivative of lua.
What’s that?

I don’t know where people got the impression it’s called LuaU but it super isn’t and never has been. It’s Luau. As in, the Hawaiian word.

this is so cool!
i wish i can contribute but
the "but"
I can’t wait for that too, what do you think people could make using this? (ideas)

Is it possible that the task library gets added to the open source version? At least task.spawn for resuming threads with no issues like with errors not showing up when you use coroutine.resume?
I understand how task.wait, task.defer, task.delay, etc (anything dependant on RunService stuff) couldn’t be added, but task.spawn is something I use quite a lot, and something that I could see being possible to add since coroutine.wrap does the same thing if you’re using functions.
It’s nice that it also still has the same meaning and is pronounced the same in Portuguese (Brazil) too 
Thanks however came up with that name.

Wow, I’m so happy to be getting into scripting at this time!
Open Sourcing is such an achievement because it allows for so many favorable possibilities!
I’m not too familiar with IDEs, but I wonder if a new IDE can be made similar to IntelliJ (a Java Devs favorite :P) because that’d be awesome!
Can’t wait to see all the amazing things which come from this.
amazing work! we’re so proud community lovely support can feature luau to open source tbh for making studio for lua skilled about that in C++ programmer can any making contributions for support source, thank you for looking how can system on working luau, that’s it how for in C++ programmer support creations from feature

Im wondering if someone could make a open-source Luau implementation of io or FileSystemService
Or I could stop being lazy and learn C++ already so I can do if myself.
We discussed io internally recently. Unsure what to think about this yet, it’s a pain not to have that in the CLI but it also breaks sandboxing for CLI-based script execution. Maybe we should do this and require explicit --io argument or consent similar to what deno does these days… we’ll see. It shouldn’t be too difficult to hook up otherwise.

Hurray! Question: How does multithreading (as in utilizing multiple CPU cores, not coroutines) work in Luau? Didn’t @zeuxcg mention something about this in RDC?
Excited to use this for my non Roblox projects.

This is the truth. Actually, open source is a major means of reducing the possibility of exploitation. Using an entire community of dedicated contributors amongst many different fields is a great way to quickly spot and eliminate vulnerabilities.

No you can’t, that’s a Roblox engine thing, not a Luau thing.
And there’s no RunService, or any other service, instances don’t exist.
However, it does mean that if you’re building / integrating with an engine, that if you in this case have events like RenderStepped, then you can move resources made by the community such as BoatTween to use your engine’s code in a much easier matter, without having to rewriting as much code.

I’m awfully late to the party but this caught my eye.
This could impact exploits because they can now see the structures without having to sift through a decompiler dump of the engine for their goodies (LuaUc-api? Play on the original luac name.) such as in original lua 5.1, luac_getglobal; the list goes on of course.
But overall not much of an impact I’d say. Though this may end up leading to exploit developers optimizing their compilers/bytecode…

You run a separate virtual machine for each thread. Synchronization between the virtual machines is to be handled by the host application embedding Luau.
Exploit developers no need to have special compilers/bytecode, they can just include Luau as a git submodule and instantly have execution with extremely fast response to Roblox updates.
I can’t wait to see a version of studio that allow the development of an offline game!
I’m so excited
That would require open sourcing the entire roblox engine, which is not the case here. This is only for the luau engine which is what all the scripts and plug-ins run on.

It’s a spelling habit, at the end of the day how it’s capitalized does not affect the product.
