Overview

This is a reworking of the wonderful lua from lua.org in Rust. It does pass the Lua 5.5 test suite, on MacOS, and includes some additional libraries and syntax (which can be disabled if required).

The goal was to provide a lua embedded environment for rust, as a sandbox for learning and to make it easier for me to write/deploy DevOps tooling.

Additional Features

Syntax
- "@" syntax for embedded scripts, which resolves their imports
- $"...{}" for interpolated -strings
- <command> ... for shell invocation
- supports { } for functions
Libraries
- midi
- dis
- fmath
- functools
- itertools
- requests
- sqlite
- toml
- tui
- urllib

Development & AI

I'd started this about 4 years ago, with a c2rust conversion and making it more idiomatic. Althought it was feature complete, it had a number of hairy bugs and progress was somewhat slow, being one of a number of weekend projects.

More recently I've used AI in three key areas which have helped me to get to this point:

slog of debugging
completing refactoring
adding additional library functionality quickly

Relationship with Lua and other upstreams

It's a downstream work, I plan to keep it up-to-date functionally with upstream Lua, where I need to embed in rust.

Can I contribute?
