	 * Tag-closer extension for CodeMirror.
	 *
	 * This extension adds an "autoCloseTags" option that can be set to
	 * either true to get the default behavior, or an object to further
	 * configure its behavior.
	 *
	 * These are supported options:
	 *
	 * `whenClosing` (default true)
	 *   Whether to autoclose when the '/' of a closing tag is typed.
	 * `whenOpening` (default true)
	 *   Whether to autoclose the tag when the final '>' of an opening
	 *   tag is typed.
	 * `dontCloseTags` (default is empty tags for HTML, none for XML)
	 *   An array of tag names that should not be autoclosed.
	 * `indentTags` (default is block tags for HTML, none for XML)
	 *   An array of tag names that should, when opened, cause a
	 *   blank line to be added inside the tag, and the blank line and
	 *   closing line to be indented.
	 * `emptyTags` (default is none)
	 *   An array of XML tag names that should be autoclosed with '/>'.
	 *
	 * See demos/closetag.html for a usage example.

				 * ## Best practices

				 * Since the position of overwriting tokens (token in `redef` that overwrite tokens in the copied language)

				 *     // at its original position
				 *     'comment': { ... },

				 *     'color': /\b(?:red|green|blue)\b/

				/**
				 * Inserts tokens _before_ another token in a language definition or any other grammar.
				 *
				 * ## Usage
				 *
				 * This helper method makes it easy to modify existing languages. For example, the CSS language definition
				 * not only defines CSS highlighting for CSS documents, but also needs to define highlighting for CSS embedded
				 * in HTML through `<style>` elements. To do this, it needs to modify `Prism.languages.markup` and add the
				 * appropriate tokens. However, `Prism.languages.markup` is a regular JavaScript object literal, so if you do
				 * this:
				 *
				 * ```js
				 * Prism.languages.markup.style = {
				 *     // token
				 * };
				 * ```
				 *
				 * then the `style` token will be added (and processed) at the end. `insertBefore` allows you to insert tokens
				 * before existing tokens. For the CSS example above, you would use it like this:
				 *
				 * ```js
				 * Prism.languages.insertBefore('markup', 'cdata', {
				 *     'style': {
				 *         // token
				 *     }
				 * });
				 * ```
				 *
				 * ## Special cases
				 *
				 * If the grammars of `inside` and `insert` have tokens with the same name, the tokens in `inside`'s grammar
				 * will be ignored.
				 *
				 * This behavior can be used to insert tokens after `before`:
				 *
				 * ```js
				 * Prism.languages.insertBefore('markup', 'comment', {
				 *     'comment': Prism.languages.markup.comment,
				 *     // tokens after 'comment'
				 * });
				 * ```
				 *
				 * ## Limitations
				 *
				 * The main problem `insertBefore` has to solve is iteration order. Since ES2015, the iteration order for object
				 * properties is guaranteed to be the insertion order (except for integer keys) but some browsers behave
				 * differently when keys are deleted and re-inserted. So `insertBefore` can't be implemented by temporarily
				 * deleting properties which is necessary to insert at arbitrary positions.
				 *
				 * To solve this problem, `insertBefore` doesn't actually insert the given tokens into the target object.
				 * Instead, it will create a new object and replace all references to the target object with the new one. This
				 * can be done without temporarily deleting properties, so the iteration order is well-defined.
				 *
				 * However, only references that can be reached from `Prism.languages` or `insert` will be replaced. I.e. if
				 * you hold the target object in a variable, then the value of the variable will not change.
				 *
				 * ```js
				 * var oldMarkup = Prism.languages.markup;
				 * var newMarkup = Prism.languages.insertBefore('markup', 'comment', { ... });
				 *
				 * assert(oldMarkup !== Prism.languages.markup);
				 * assert(newMarkup === Prism.languages.markup);
				 * ```
				 *
				 * @param {string} inside The property of `root` (e.g. a language id in `Prism.languages`) that contains the
				 * object to be modified.
				 * @param {string} before The key to insert before.
				 * @param {Grammar} insert An object containing the key-value pairs to be inserted.
				 * @param {Object<string, any>} [root] The object containing `inside`, i.e. the object that contains the

	 * Creates a debounced function that delays invoking `func` until after `wait`
	 * milliseconds have elapsed since the last time the debounced function was
	 * invoked. The debounced function comes with a `cancel` method to cancel
	 * delayed `func` invocations and a `flush` method to immediately invoke them.
	 * Provide `options` to indicate whether `func` should be invoked on the
	 * leading and/or trailing edge of the `wait` timeout. The `func` is invoked
	 * with the last arguments provided to the debounced function. Subsequent
	 * calls to the debounced function return the result of the last `func`
	 * invocation.

	 * **Note:** If `leading` and `trailing` options are `true`, `func` is
	 * invoked on the trailing edge of the timeout only if the debounced function
	 * is invoked more than once during the `wait` timeout.
	 *
	 * If `wait` is `0` and `leading` is `false`, `func` invocation is deferred
	 * until to the next tick, similar to `setTimeout` with a timeout of `0`.

	     * 开始进行懒加载
	     *
	     * **关于实现方式的思考**
	     * 实现图片懒加载一般有三种方式：
	     *  1、监听滚动事件，滚动到视野内的图片开始加载
	     *  2、定时检测当前视窗内是否有图片需要加载
	     *  3、当前一张图片加载完成后，自动加载下一张图片
	     *
	     * 方式1监听滚动事件的弊端：
	     *  1、需要限频率
	     *  2、不能实现自动加载所有图片的功能（autoLoadImgNum = -1）
	     *  3、如果业务方对预览区域做了个性化加工，有可能导致监听不到滚动事件
	     *  4、在自动滚动到锚点的场景，会在页面滚动时加载图片，图片的加载会导致锚点上方的元素高度发生变化，最终导致锚点定位失败
	     *      （所以在这个场景下，需要特殊处理图片加载的时机，但并不好判断是否锚点引发的滚动）
	     *  5、浏览器尺寸发生变化或者浏览器缩放比例发生变化的场景（当然还有横屏竖屏切换、系统分辨率改变等）不好监听和响应
	     *
	     * 方式2轮询的弊端：
	     *  1、需要额外的逻辑来控制并发
	     *  2、消耗计算资源，所以需要尽量优化单次计算量，并尽量避免在轮询里进行大范围dom操作
	     *  3、两次图片加载中间可能有最大轮询间隔的空闲时间浪费
	     *
	     * 方式3依次加载的弊端：
	     *  1、没办法实现滚动到视野内再加载图片
	     *
	     * 综合考虑决定用方式2（轮询）+方式3（依次加载）的组合方式，并且每次只做一次dom写操作
	     * 轮询带来的性能开销就让受摩尔定律加持的硬件和每月都会更新版本的浏览器们愁去吧

	// Notable changes from Slick.Parser 1.0.x

	// The parser now uses 2 classes: Expressions and Expression
	// `new Expressions` produces an array-like object containing a list of Expression objects
	// - Expressions::toString() produces a cleaned up expressions string
	// `new Expression` produces an array-like object
	// - Expression::toString() produces a cleaned up expression string
	// The only exposed method is parse, which produces a (cached) `new Expressions` instance
	// parsed.raw is no longer present, use .toString()
	// parsed.expression is now useless, just use the indices
	// parsed.reverse() has been removed for now, due to its apparent uselessness
	// Other changes in the Expressions object:
	// - classNames are now unique, and save both escaped and unescaped values
	// - attributes now save both escaped and unescaped values
	// - pseudos now save both escaped and unescaped values
