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() {\n\n/* GENERATED_BUILD_OUTPUT */\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// 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, { enumerable: true, get: getter });\n/******/ \t\t}\n/******/ \t};\n/******/\n/******/ \t// define __esModule on exports\n/******/ \t__webpack_require__.r = function(exports) {\n/******/ \t\tif(typeof Symbol !== 'undefined' && Symbol.toStringTag) {\n/******/ \t\t\tObject.defineProperty(exports, Symbol.toStringTag, { value: 'Module' });\n/******/ \t\t}\n/******/ \t\tObject.defineProperty(exports, '__esModule', { value: true });\n/******/ \t};\n/******/\n/******/ \t// create a fake namespace object\n/******/ \t// mode & 1: value is a module id, require it\n/******/ \t// mode & 2: merge all properties of value into the ns\n/******/ \t// mode & 4: return value when already ns object\n/******/ \t// mode & 8|1: behave like require\n/******/ \t__webpack_require__.t = function(value, mode) {\n/******/ \t\tif(mode & 1) value = __webpack_require__(value);\n/******/ \t\tif(mode & 8) return value;\n/******/ \t\tif((mode & 4) && typeof value === 'object' && value && value.__esModule) return value;\n/******/ \t\tvar ns = Object.create(null);\n/******/ \t\t__webpack_require__.r(ns);\n/******/ \t\tObject.defineProperty(ns, 'default', { enumerable: true, value: value });\n/******/ \t\tif(mode & 2 && typeof value != 'string') for(var key in value) __webpack_require__.d(ns, key, function(key) { return value[key];

style_html(html_source, options);\n\n The options are:\n indent_inner_html (default false) — indent and sections,\n indent_size (default 4) — indentation size,\n indent_char (default space) — character to indent with,\n wrap_line_length (default 250) - maximum amount of characters per line (0 = disable)\n brace_style (default \"collapse\") - \"collapse\" | \"expand\" | \"end-expand\" | \"none\"\n put braces on the same line as control statements (default), or put braces on own line (Allman / ANSI style), or just put end braces on own line, or attempt to keep them where they are.\n inline (defaults to inline tags) - list of tags to be considered inline tags\n unformatted (defaults to inline tags) - list of tags, that shouldn't be reformatted\n content_unformatted (defaults to [\"pre\", \"textarea\"] tags) - list of tags, whose content shouldn't be reformatted\n indent_scripts (default normal) - \"keep\"|\"separate\"|\"normal\"\n preserve_newlines (default true) - whether existing line breaks before elements should be preserved\n Only works before elements, not inside tags or for text.\n max_preserve_newlines (default unlimited) - maximum number of line breaks to be preserved in one chunk\n indent_handlebars (default false) - format and indent {{#foo}} and {{/foo}}\n end_with_newline (false) - end with a newline\n extra_liners (default [head,body,/html]) -List of tags that should have an extra newline before them.\n\n e.g.\n\n style_html(html_source, {\n 'indent_inner_html': false,\n 'indent_size': 2,\n 'indent_char': ' ',\n 'wrap_line_length': 78,\n
