Lines will continue until a point where a newline would\n be preserved if it were present.\n\n end_with_newline (default false) - end output with a newline\n\n\n e.g\n\n js_beautify(js_source_text, {\n 'indent_size': 1,\n 'indent_char': '\\t'\n });\n\n*/\n\n(function() {\nvar legacy_beautify_js =\n/******/ (function(modules) { // webpackBootstrap\n/******/ \t// The module cache\n/******/ \tvar installedModules = {};\n/******/\n/******/ \t// The require function\n/******/ \tfunction __webpack_require__(moduleId) {\n/******/\n/******/ \t\t// Check if module is in cache\n/******/ \t\tif(installedModules[moduleId]) {\n/******/ \t\t\treturn installedModules[moduleId].exports;\n/******/ \t\t}\n/******/ \t\t// Create a new module (and put it into the cache)\n/******/ \t\tvar module = installedModules[moduleId] = {\n/******/ \t\t\ti: moduleId,\n/******/ \t\t\tl: false,\n/******/ \t\t\texports: {}\n/******/ \t\t};\n/******/\n/******/ \t\t// Execute the module function\n/******/ \t\tmodules[moduleId].call(module.exports, module, module.exports, __webpack_require__);\n/******/\n/******/ \t\t// Flag the module as loaded\n/******/ \t\tmodule.l = true;\n/******/\n/******/ \t\t// Return the exports of the module\n/******/ \t\treturn module.exports;\n/******/ \t}\n/******/\n/******/\n/******/ \t// expose the modules object (__webpack_modules__)\n/******/ \t__webpack_require__.m = modules;\n/******/\n/******/ \t// expose the module cache\n/******/ \t__webpack_require__.c = installedModules;\n/******/\n/******/ \t// identity function for calling harmony imports with the correct context\n/******/ \t__webpack_require__.i = function(value) { return value; };\n/******/\n/******/ \t// define getter function for harmony exports\n/******/ \t__webpack_require__.d = function(exports, name, getter) {\n/******/ \t\tif(!__webpack_require__.o(exports, name)) {\n/******/ \t\t\tObject.defineProperty(exports, name, {\n/******/ \t\t\t\tconfigurable: false,\n/******/ \t\t\t\tenumerable: true,\n/******/ \t\t\t\tget: getter\n/******/ \t\t\t});\n/******/ \t\t}\n/******/ \t};\n/******/\n/******/ \t// getDefaultExport function for compatibility with non-harmony modules\n/******/ \t__webpack_require__.n = function(module) {\n/******/ \t\tvar getter = module && module.__esModule ?\n/******/ \t\t\tfunction getDefault() { return module['default']; } :\n/******/ \t\t\tfunction getModuleExports() { return module; };\n/******/ \t\t__webpack_require__.d(getter, 'a', getter);\n/******/ \t\treturn getter;\n/******/ \t};\n/******/\n/******/ \t// Object.prototype.hasOwnProperty.call\n/******/ \t__webpack_require__.o = function(object, property) { return Object.prototype.hasOwnProperty.call(object, property); };\n/******/\n/******/ \t// __webpack_public_path__\n/******/ \t__webpack_require__.p = \"\";\n/******/\n/******/ \t// Load entry module and return exports\n/******/ \treturn __webpack_require__(__webpack_require__.s = 6);\n/******/ })\n/************************************************************************/\n/******/ ([\n/* 0 */\n/***/ (function(module, exports) {\n\n/* jshint curly: false */\n// This section of code is taken from acorn.\n//\n// Acorn was written by Marijn Haverbeke and released under an MIT\n// license.
