Can be called without `new`.\n *\n * ##### presetName\n *\n * MarkdownIt provides named presets as a convenience to quickly\n * enable/disable active syntax rules and options for common use cases.\n *\n * - [\"commonmark\"](https://github.com/markdown-it/markdown-it/blob/master/lib/presets/commonmark.js) -\n * configures parser to strict [CommonMark](http://commonmark.org/) mode.\n * - [default](https://github.com/markdown-it/markdown-it/blob/master/lib/presets/default.js) -\n * similar to GFM, used when no preset name given. Enables all available rules,\n * but still without html, typographer & autolinker.\n * - [\"zero\"](https://github.com/markdown-it/markdown-it/blob/master/lib/presets/zero.js) -\n * all rules disabled. Useful to quickly setup your config via `.enable()`.\n * For example, when you need only `bold` and `italic` markup and nothing else.\n *\n * ##### options:\n *\n * - __html__ - `false`. Set `true` to enable HTML tags in source. Be careful!\n * That's not safe! You may need external sanitizer to protect output from XSS.\n * It's better to extend features via plugins, instead of enabling HTML.\n * - __xhtmlOut__ - `false`. Set `true` to add '/' when closing single tags\n * (`<br />`). This is needed only for full CommonMark compatibility. In real\n * world you will need HTML output.\n * - __breaks__ - `false`. Set `true` to convert `\\n` in paragraphs into `<br>`.\n * - __langPrefix__ - `language-`. CSS language class prefix for fenced blocks.\n * Can be useful for external highlighters.\n * - __linkify__ - `false`. Set `true` to autoconvert URL-like text to links.\n * - __typographer__ - `false`. Set `true` to enable [some language-neutral\n * replacement](https://github.com/markdown-it/markdown-it/blob/master/lib/rules_core/replacements.js) +\n * quotes beautification (smartquotes).\n * - __quotes__ - `“”‘’`, String or Array. Double + single quotes replacement\n * pairs, when typographer enabled and smartquotes on. For example, you can\n * use `'«»„“'` for Russian, `'„“‚‘'` for German, and\n * `['«\\xA0', '\\xA0»', '‹\\xA0', '\\xA0›']` for French (including nbsp).\n * - __highlight__ - `null`. Highlighter function for fenced code blocks.\n * Highlighter `function (str, lang)` should return escaped HTML. It can also\n * return empty string if the source was not changed and should be escaped\n * externaly. If result starts with <pre... internal wrapper is skipped.\n *\n * ##### Example\n *\n * ```javascript\n * // commonmark mode\n * var md = require('markdown-it')('commonmark');\n *\n * // default mode\n * var md = require('markdown-it')();\n *\n * // enable everything\n * var md = require('markdown-it')({\n * html: true,\n * linkify: true,\n * typographer: true\n * });\n * ```\n *\n * ##### Syntax highlighting\n *\n * ```js\n * var hljs = require('highlight.js') // https://highlightjs.org/\n *\n * var md = require('markdown-it')({\n * highlight: function (str, lang) {\n * if (lang && hljs.getLanguage(lang)) {\n * try {\n * return hljs.highlight(lang, str, true).value;\n * } catch (__) {}\n * }\n *\n * return ''; // use external default escaping\n * }\n * });\n * ```\n *\n * Or with full wrapper override (if you need assign class to `<pre>`):\n *\n * ```javascript\n * var hljs = require('highlight.js') // https://highlightjs.org/\n *\n * // Actual default values\n * var md = require('markdown-it')({\n * highlight: function (str, lang) {\n * if (lang && hljs.getLanguage(lang)) {\n * try {\n * return '<pre class=\"hljs\"><code>' +\n * hljs.highlight(lang, str, true).value +\n * '</code></pre>';\n * } catch (__) {}\n * }\n *\n * return '<pre class=\"hljs\"><code>' + md.utils.escapeHtml(str) + '</code></pre>';\n * }\n * });\n * ```\n *\n **/\n\n\nfunction MarkdownIt(presetName, options) {\n if (!(this instanceof MarkdownIt)) {\n return new MarkdownIt(presetName, options);\n }\n\n if (!options) {\n if (!utils.isString(presetName)) {\n options = presetName || {};\n presetName = 'default';\n }\n }\n /**\n * MarkdownIt#inline -> ParserInline\n *\n * Instance of [[ParserInline]].

Handler functions are\n// called one at a time, starting with the base props and then\n// searching through the plugins (in order of appearance) until one of\n// them returns true. For some props, the first plugin that yields a\n// value gets precedence.\n//\n// handleDOMEvents:: ?Object<(view: EditorView, event: dom.Event) → bool>\n// Can be an object mapping DOM event type names to functions that\n// handle them. Such functions will be called before any handling\n// ProseMirror does of events fired on the editable DOM element.\n// Contrary to the other event handling props, when returning true\n// from such a function, you are responsible for calling\n// `preventDefault` yourself (or not, if you want to allow the\n// default behavior).\n//\n// handleKeyDown:: ?(view: EditorView, event: dom.KeyboardEvent) → bool\n// Called when the editor receives a `keydown` event.\n//\n// handleKeyPress:: ?(view: EditorView, event: dom.KeyboardEvent) → bool\n// Handler for `keypress` events.\n//\n// handleTextInput:: ?(view: EditorView, from: number, to: number, text: string) → bool\n// Whenever the user directly input text, this handler is called\n// before the input is applied.

Should map node and mark names to constructor\n// functions that produce a [`NodeView`](#view.NodeView) object\n// implementing the node's display behavior. For nodes, the third\n// argument `getPos` is a function that can be called to get the\n// node's current position, which can be useful when creating\n// transactions to update it. For marks, the third argument is a\n// boolean that indicates whether the mark's content is inline.\n//\n// `decorations` is an array of node or inline decorations that are\n// active around the node. They are automatically drawn in the\n// normal way, and you will usually just want to ignore this, but\n// they can also be used as a way to provide context information to\n// the node view without adding it to the document itself.\n//\n// clipboardSerializer:: ?DOMSerializer\n// The DOM serializer to use when putting content onto the\n// clipboard. If not given, the result of\n// [`DOMSerializer.fromSchema`](#model.DOMSerializer^fromSchema)\n// will be used.\n//\n// clipboardTextSerializer:: ?(Slice) → string\n// A function that will be called to get the text for the current\n// selection when copying text to the clipboard. By default, the\n// editor will use [`textBetween`](#model.Node.textBetween) on the\n// selected range.\n//\n// decorations:: ?(state: EditorState) → ?DecorationSet\n// A set of [document decorations](#view.Decoration) to show in the\n// view.\n//\n// editable:: ?(state: EditorState) → bool\n// When this returns false, the content of the view is not directly\n// editable.\n//\n// attributes:: ?union<Object<string>, (EditorState) → ?Object<string>>\n// Control the DOM attributes of the editable element. May be either\n// an object or a function going from an editor state to an object.\n// By default, the element will get a class `\"ProseMirror\"`, and\n// will have its `contentEditable` attribute determined by the\n// [`editable` prop](#view.EditorProps.editable). Additional classes\n// provided here will be added to the class. For other attributes,\n// the value provided first (as in\n// [`someProp`](#view.EditorView.someProp)) will be used.\n//\n// scrollThreshold:: ?union<number, {top: number, right: number, bottom: number, left: number}>\n// Determines the distance (in pixels) between the cursor and the\n// end of the visible viewport at which point, when scrolling the\n// cursor into view, scrolling takes place. Defaults to 0.\n//\n// scrollMargin:: ?union<number, {top: number, right: number, bottom: number, left: number}>\n// Determines the extra space (in pixels) that is left above or\n// below the cursor when it is scrolled into view. Defaults to 5.\n// DirectEditorProps:: interface extends EditorProps\n//\n// The props object given directly to the editor view supports two\n// fields that can't be used in plugins:\n//\n// state:: EditorState\n// The current state of the editor.\n//\n// dispatchTransaction:: ?(tr: Transaction)\n// The callback over which to send transactions (state updates)\n// produced by the view. If you specify this, you probably want to\n// make sure this ends up calling the view's\n// [`updateState`](#view.EditorView.updateState) method with a new\n// state that has the transaction\n// [applied](#state.EditorState.apply). The callback will be bound to have\n// the view instance as its `this` binding.\n\n\n\n\n//# sourceURL=webpack:///./node_modules/prosemirror-view/dist/index.es.js?");
