// iMacro CheatSheet - Command Reference
// http://wiki.imacros.net/Command_Reference


// iMacros supports 3 types of variables:
// * The macro variables !VAR0 thru !VAR9. They can be used with the SET and ADD command inside a macro.
// * Built-in variables. They contain certain values set by iMacros.
// * User-defined variables. They are defined in-macro using the SET command.

This blogpost shows how to setup Rails 6 with Bootstrap 4.

This snippet shows a somehow different and less customized approach.

$ rails new rails6-bootstrap4
$ bundle --binstubs
$ yarn add bootstrap jquery popper.js expose-loader

import { Controller } from "stimulus"
import { DirectUpload } from "@rails/activestorage"
import Dropzone from "dropzone"
import { getMetaValue, findElement, removeElement, insertAfter } from "helpers"

Dropzone.autoDiscover = false

export default class extends Controller {
  static targets = [ "input" ]
