- **`unit` must not be `nil`**: Lua tables cannot hold `nil` values, so

# Purescript Backend for Lua

[![Purescript Lua CI](https://github.com/Unisay/purescript-lua/actions/workflows/ci.yaml/badge.svg)](https://github.com/Unisay/purescript-lua/actions/workflows/ci.yaml)

🔋 Status: (2024-04-20) the project is in the "_ready to be experimented with_" state (read: it likely contains bugs but is already usable).

💡 If you have an idea on how to use Purescript to Lua compilation please contribute it here:

## Features

- [x] Lua code bundling: emits either a Lua module (a file that returns a table with functions) or an application (a file that executes itself).
- [x] FFI with Lua.
- [x] Dead Code Elimination (DCE).
- [x] Code inlining.
- [x] [Package Set](https://github.com/Unisay/purescript-lua-package-sets) for PureScript/Lua libs.
- [x] [Package Set](https://github.com/purescript-lua/purescript-lua-package-sets) for PureScript/Lua libs.
- [x] All core libs added to the package set.
