retidy's Issues

Support for WebpackJsonp

Hello, it would be fantastic to have support for files in the form of

(window.webpackJsonp = window.webpackJsonp || []).push(/* ... */);

Any way of making this work, please? 🙏🏻

unminifyIfStatements causes bug

unminify-if-statements.ts

return x || a() -> if (!x) { return a() }

when x is true, it returns undefined

I disabled this transformer to make it work

Running a retidy test app: TypeError: not a webpackBootstrap function call AST

Hello,
I'm trying to debundle a very short react file using retidy.
This is my test.js file:

test.js

import retidy from "retidy"
import fs from "fs"
const code = fs.readFileSync("vendor-bundle.js", "utf-8")
retidy.retidy(code, { type: "webpack-jsonp", outDir: "./out/", bundleAstReferenceKeys: ["body", 0, "expression"] })

This is the file to be unbundled:

vendor-bundle.js
!function(e){function n(t){if(r[t])return r[t].exports;var o=r[t]={exports:{},id:t,loaded:!1};return e[t].call(o.exports,o,o.exports,n),o.loaded=!0,o.exports}var t=window.webpackJsonp;window.webpackJsonp=function(a,l){for(var p,c,s=0,i=[];s<a.length;s++)c=a[s],o[c]&&i.push.apply(i,o[c]),o[c]=0;for(p in l)e[p]=l[p];for(t&&t(a,l);i.length;)i.shift().call(null,n);return l[0]?(r[0]=0,n(0)):void 0};var r={},o={4:0,6:0};n.e=function(e,t){if(0===o[e])return t.call(null,n);if(void 0!==o[e])o[e].push(t);else{o[e]=[t];var r=document.getElementsByTagName("head")[0],a=document.createElement("script");a.type="text/javascript",a.charset="utf-8",a.async=!0,a.src=n.p+""+e+"."+({5:"bundle",6:"common-bundle"}[e]||e)+".js",r.appendChild(a)}},n.m=e,n.c=r,n.p=""}([]);

This is my package.json:

package.json

{
  "name": "testapp",
  "version": "1.0.0",
  "type": "module",
  "description": "",
  "main": "test.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "retidy": "^1.5.1"
  }
}

And I have a common-bundle.js file:
common-bundle.js
webpackJsonp([6,4],[]);

This is the error i get running node --trace-warnings test.js:

I'm doing something wrong for sure, but I don't know what.
And I have no idea of what to write in the bundleAstReferenceKeys (and maybe in entryPoint option too)
Could someone help me?
Thanks
