PureScript Lua Package Set

The package set for pslua, the PureScript-to-Lua compiler backend. It collects the core PureScript libraries as Lua forks: each fork keeps the upstream PureScript sources and replaces the JavaScript FFI with Lua that runs on Lua 5.1.

src/packages.json is the source of truth: it lists only the Lua forks. Each psc-* release folds it onto a pinned upstream PureScript registry set and publishes the result as packages.json, a complete set you consume directly with the new spago.

Using the set with spago

Point workspace.packageSet.url at a released packages.json:

workspace:
  packageSet:
    url: https://github.com/purescript-lua/purescript-lua-package-sets/releases/download/psc-0.15.15-20260624/packages.json

That set already carries the Lua forks in place of their JavaScript-targeting upstreams, so you just list what you need under package.dependencies: no extraPackages block and no merge. Releases are tagged psc-0.15.15-<YYYYMMDD>[-N]; latest-compatible-sets.json records the most recent one.

The set targets the new spago (spago.yaml/spago.lock). spago 0.21 / Dhall is no longer supported.

Packages

The Lua forks in this set. Each keeps its upstream PureScript API and ships a Lua FFI in place of the JavaScript one. The package name is the key in src/packages.json; note that the OpenResty bindings are keyed lua-ngx.

Every other package in the set is an unmodified PureScript package that needs no Lua-specific FFI.

Maintaining a fork

CONTRIBUTING.md is the practical canon: the toolchain, the Lua 5.1 and FFI rules, CI, and the release process. The reasoning behind each rule is recorded as an ADR under docs/adr/. Read the ADRs before a decision that affects the whole set, and add one after making such a decision.
