I wanted to announce the stable release of a project started at TV Labs, called Lua.
Features
~LUAsigil for validating Lua code at compile-timedefluamacro for exposing Elixir functions to Lua- Improved error messages and sandboxing
- Deep setting/getting variables and state
- Excellent documentation and guides for working with Luerl
Lua the Elixir library vs Lua the language {: .info}
When referring to this library,

From the blog post
The first stable release of the Elixir library, Lua v0.1.0, has been released to hex.pm!
Lua is a library that allows you to execute arbitrary, sandboxed Lua programs directly on the BEAM VM. This is not embedding the C Lua runtime and compiler, but rather a complete implementation of Lua 5.3. This feat is made possible by the underlying Luerl library, which implements a Lua parser, compiler, and runtime, all in Erlang.
The Lua Elixir library extends the capabilities of the Luerl library, improving error messages and providing robust documentation.

This looks excellent, excited to play with it and keeping an eye out for future luerl updates!

Ha, congrats on the release! I did not realized I’d happened upon something that hadn’t been officially announced yet when asking this

I have released version v0.2.0
[v0.2.0] - 2025-05-14
Changed
defluafunction, or a function set byLua.set!/3is now validated. If the data is not an identity value, or an encoded value, it will raise an exception. In the past,Luaand Luerl would happily accept bad values, causing downstream problems in the program. This led to unexpected behavior, where depending on if the data passed was decoded or not, the program would succeed or failFull Changelog: Comparing v0.1.1...v0.2.0 · tv-labs/lua · GitHub

Lua v1.0.0 and now v1.0.2 have been released!
It is a full rewrite of Lua from the ground up, implementing a full lexer/parser, compiler, and virtual machine, all in pure Elixir.
I have also built a companion website with a language tour and playground for you to test it out! There will be a blog post with more details about how it was built and used in the coming weeks.

I have a soft spot for Lua. This is great
