WEATHER CAL CONVERTER
=====================
   ~ by @mzeryck ~   

This script converts Scriptable widgets into Weather Cal widget items. Read this entire comment before you begin.

BEFORE YOU START
================

You may need to modify your Weather Cal widget script, since it doesn't get updated when you run the "Update code" function. 

Find this line of code:
const code = importModule(codeFilename)

Paste this code directly after it:
const custom = {
  // Custom items and backgrounds can be added here.

}

Then, find this line of code:
const widget = await code.createWidget(layout, Script.name(), iCloudInUse)

Modify it so it looks like this:
const widget = await code.createWidget(layout, Script.name(), iCloudInUse, custom)


HOW THIS SCRIPT WORKS
=====================

- When you run this script, choose a name. This is the word you'll be adding to the Weather Cal layout.
- Select the file containing the widget script.
- When it displays the code, use the share icon in the top right to copy the text.
- Open a Weather Cal widget script and paste the code into the custom object after the comment. If you're pasting multiple items, make sure to paste it after the previous comma but before the final bracket.
- In your Weather Cal layout, add the name of your new widget item.


*********************

PLEASE NOTE
===========

Doing this without modifying the output will usually break the "Show widget preview" function of Weather Cal. This is because many widgets will detect that they're running in the Scriptable app and attempt to show their own preview or change their behavior. However, the widget will still work fine on your home screen.
