psimp

This is an attempt to extract PureScript's CoreImp AST for dynamically typed imperative languages.

It is based on a past coreimp work

The design concept is to provide a simpler AST rather than performance considerations.

Transpile target languages:

• JavaScript
• Lua
• Dart

Requirements

• yarn
• node ✅v14.4.0
• lua ✅v5.3.5
• dart ✅v2.8.4

Requirements with Nix

A simple way to get the requirements in Nix is to use a one-liner nix-shell command. For instance, if you are just in lua but not dart, you could do:

nix-shell -p lua yarn nodejs

Code Generation

First, generate example modules' corefn.json files to ./example/output

yarn example

JavaScript

Generate JavaScript files to ./js/outjs (FFI files copied from ./example/output)

yarn js:codegen

Run

yarn js:execute

Lua

Generate Lua files to ./lua/outlua

yarn lua:codegen

Copy FFI files (manually for now) from pslua-ffi

cp -r [clonedir]/pslua-ffi/effect/* ./lua/outlua
cp -r [clonedir]/pslua-ffi/console/* ./lua/outlua
cp -r [clonedir]/pslua-ffi/prelude/* ./lua/outlua

Run

yarn lua:execute

Dart

Generate Dart files to ./dart/outdart

yarn dart:codegen

Copy FFI files (manually for now) from psdart-ffi

cp -r [clonedir]/psdart-ffi/effect/* ./dart/outdart
cp -r [clonedir]/psdart-ffi/console/* ./dart/outdart
cp -r [clonedir]/psdart-ffi/prelude/* ./dart/outdart

Run

yarn dart:execute

Memo

It is not cut out as a library for now, but is a monorepo to modify and check the model easily.
