// marker continues beyond the start/end of the line. Markers have
// links back to the lines they currently touch.

/**
 * The Component object represents a single node of our template structure, so when you update its properties the changes are
 * immediately reflected on the canvas and in the code to export (indeed, when you ask to export the code we just go through all
 * the tree of nodes).
 * An example on how to update properties:
 * ```js
 * component.set({
 *  tagName: 'span',
 *  attributes: { ... },
 *  removable: false,
 * });
 * component.get('tagName');
 * // -> 'span'
 * ```
 *
 * @typedef Component
 * @property {String} [type=''] Component type, eg. `text`, `image`, `video`, etc.
 * @property {String} [tagName='div'] HTML tag of the component, eg. `span`. Default: `div`
 * @property {Object} [attributes={}] Key-value object of the component's attributes, eg. `{ title: 'Hello' }` Default: `{}`
 * @property {String} [name=''] Name of the component. Will be used, for example, in Layers and badges
 * @property {Boolean} [removable=true] When `true` the component is removable from the canvas, default: `true`
 * @property {Boolean|String} [draggable=true] Indicates if it's possible to drag the component inside others.
 *  You can also specify a query string to indentify elements,
 *  eg. `'.some-class[title=Hello], [data-gjs-type=column]'` means you can drag the component only inside elements
 *  containing `some-class` class and `Hello` title, and `column` components. Default: `true`
 * @property {Boolean|String} [droppable=true] Indicates if it's possible to drop other components inside. You can use
 * a query string as with `draggable`. Default: `true`
 * @property {Boolean} [badgable=true] Set to false if you don't want to see the badge (with the name) over the component. Default: `true`
 * @property {Boolean|Array<String>} [stylable=true] True if it's possible to style the component.
 * You can also indicate an array of CSS properties which is possible to style, eg. `['color', 'width']`, all other properties
 * will be hidden from the style manager. Default: `true`
 * @property {Array<String>} [stylable-require=[]] Indicate an array of style properties to show up which has been marked as `toRequire`. Default: `[]`
 * @property {Array<String>} [unstylable=[]] Indicate an array of style properties which should be hidden from the style manager. Default: `[]`
 * @property {Array<String>} [style-signature=''] This option comes handy when you need to remove or export strictly component-specific rules. Be default, if this option is not empty, the editor will remove rules when there are no components, of that type, in the canvas. Eg. '['.navbar', '[navbar-']'. Default: `''`
 * @property {Boolean} [highlightable=true] It can be highlighted with 'dotted' borders if true. Default: `true`
 * @property {Boolean} [copyable=true] True if it's possible to clone the component. Default: `true`
 * @property {Boolean} [resizable=false] Indicates if it's possible to resize the component. It's also possible to pass an object as [options for the Resizer](https://github.com/artf/grapesjs/blob/master/src/utils/Resizer.js). Default: `false`
 * @property {Boolean} [editable=false] Allow to edit the content of the component (used on Text components). Default: `false`
 * @property {Boolean} [layerable=true] Set to `false` if you need to hide the component inside Layers. Default: `true`
 * @property {Boolean} [selectable=true] Allow component to be selected when clicked. Default: `true`
 * @property {Boolean} [hoverable=true] Shows a highlight outline when hovering on the element if `true`. Default: `true`
 * @property {Boolean} [void=false] This property is used by the HTML exporter as void elements don't have closing tags, eg. `<br/>`, `<hr/>`, etc. Default: `false`
 * @property {String} [content=''] Content of the component (not escaped) which will be appended before children rendering. Default: `''`
 * @property {String} [icon=''] Component's icon, this string will be inserted before the name (in Layers and badge), eg. it can be an HTML string '<i class="fa fa-square-o"></i>'. Default: `''`
 * @property {String|Function} [script=''] Component's javascript. More about it [here](/modules/Components-js.html). Default: `''`
 * @property {Array<Object|String>} [traits=''] Component's traits. More about it [here](/modules/Traits.html). Default: `['id', 'title']`
 * @property {Array<String>} [propagate=[]] Indicates an array of properties which will be inhereted by all NEW appended children.
 *  For example if you create a component likes this: `{ removable: false, draggable: false, propagate: ['removable', 'draggable'] }`
 *  and append some new component inside, the new added component will get the exact same properties indicated in the `propagate` array (and the `propagate` property itself). Default: `[]`
 * @property {Array<Object>} [toolbar=null] Set an array of items to show up inside the toolbar when the component is selected (move, clone, delete).
 * Eg. `toolbar: [ { attributes: {class: 'fa fa-arrows'}, command: 'tlb-move' }, ... ]`.
 * By default, when `toolbar` property is falsy the editor will add automatically commands like `move`, `delete`, etc. based on its properties.
 * @property {Collection<Component>} [components=null] Children components. Default: `null`

    * Editor contains the top level API which you'll probably use to customize the editor or extend it with plugins.
    * You get the Editor instance on init method and you can pass options via its [Configuration Object](https://github.com/artf/grapesjs/blob/master/src/editor/config/config.js)
    *
    * ```js
    * const editor = grapesjs.init({
    *    // options

    * ```
    *
    * ## Available Events
    *
    * You can make use of available events in this way

    *    // do something
    * })
    * ```
    *

    * * `block:drag` - Dragging block, the block's model and the drag event are passed as arguments
    * * `block:drag:stop` - Dragging of the block is stopped. As agruments for the callback you get, the dropped component model (if dropped successfully) and the model of the block
    * ### Assets

    * Selectors in GrapesJS are used in CSS Composer inside Rules and in Components as classes. To get better this concept let's take
    * a look at this code:
    *
    * ```css
    * span > #send-btn.btn{
    *  ...
    * }
    * ```
    * ```html
    * <span>
    *   <button id="send-btn" class="btn"></button>
    * </span>
    * ```
    *
    * In this scenario we get:
    * * span     -> selector of type `tag`
    * * send-btn -> selector of type `id`
    * * btn      -> selector of type `class`
    *
    * So, for example, being `btn` the same class entity it'll be easier to refactor and track things.
    *
    * You can customize the initial state of the module from the editor initialization, by passing the following [Configuration Object](https://github.com/artf/grapesjs/blob/master/src/selector_manager/config/config.js)
    * ```js
    * const editor = grapesjs.init({
    *  selectorManager: {
    *    // options
    *  }
    * })
    * ```
    *
    * Once the editor is instantiated you can use its API. Before using these methods you should get the module from the instance
    *
    * ```js
    * const selectorManager = editor.SelectorManager;
    * ```
    *
    * * [getConfig](#getconfig)
    * * [add](#add)
    * * [addClass](#addclass)
