This project is a work in progress. Please do not use this (yet) if you need a fully featured and/or compliant Lua interpreter.

A Lua compiler and interpreter fully written in Rust. This project aims to provide a fully compliant Lua implementation including interoperability between Lua and Rust.

Things to do and implement

A list of features to be implemented, in somewhat particular order:

• [x] (Almost) full language syntax support
• [ ] Proper errors handling with trace+context
• [ ] Rust-Lua interoperability
• [ ] Standard libraries
  • [ ] Basic library
  • [ ] Coroutine library
  • [ ] Package library
  • [ ] String manipulation
  • [ ] Basic UTF-8 support
  • [ ] Table manipulation
  • [ ] Mathematical functions
  • [ ] Input and output
  • [ ] Operating system facilities
  • [ ] Debug facilities
• [ ] Garbage collector
• [ ] Passing the Lua test suite
• [ ] Benchmarks vs the C implementation
• [ ] REPL

Testing

This crate has its own test suite that can be executed with cargo test. A copy of the Lua test suite has also been included in this repository. These tests can be run by running them as regular Lua files cargo run -- <file>.lua, the test is considered passed if the output ends with "OK" and the interpreter has returned without error.
