ClipboardMarkersUtils (clipboard)

@ckeditor/ckeditor5-clipboard/src/clipboardmarkersutils

Properties

• readonly inherited

  editor : Editormodule:clipboard/clipboardmarkersutils~ClipboardMarkersUtils#editor

  See source

  The editor instance.

  Note that most editors implement the ui property. However, editors with an external UI (i.e. Bootstrap-based) or a headless editor may not have this property or throw an error when accessing it.

  Because of above, to make plugins more universal, it is recommended to split features into:

  • The "editing" part that uses the Editor class without ui property.
  • The "UI" part that uses the Editor class and accesses ui property.

• inherited observable

  isEnabled : booleanmodule:clipboard/clipboardmarkersutils~ClipboardMarkersUtils#isEnabled

  See source

  Flag indicating whether a plugin is enabled or disabled. A disabled plugin will not transform text.

  Plugin can be simply disabled like that:

  // Disable the plugin so that no toolbars are visible.
  editor.plugins.get( 'TextTransformation' ).isEnabled = false;
  

  You can also use forceDisabled method.

• internal

  _markersToCopy : Map<string, ClipboardMarkerConfiguration>module:clipboard/clipboardmarkersutils~ClipboardMarkersUtils#_markersToCopy

  See source

  Map of marker names that can be copied.

  bind( bindProperty1, bindProperty2 ) → DualBindChain<K1, ClipboardMarkersUtils[ K1 ], K2, ClipboardMarkersUtils[ K2 ]>module:clipboard/clipboardmarkersutils~ClipboardMarkersUtils#bind:DUAL_BIND

  See source

  Binds observable properties to other objects implementing the Observable interface.

  Read more in the dedicated guide covering the topic of property bindings with some additional examples.

  Consider two objects: a button and an associated command (both Observable).

  A simple property binding could be as follows:

  button.bind( 'isEnabled' ).to( command, 'isEnabled' );
  

  or even shorter:

  button.bind( 'isEnabled' ).to( command );
  

  which works in the following way:

  • button.isEnabled instantly equals command.isEnabled,
  • whenever command.isEnabled changes, button.isEnabled will immediately reflect its value.

  Note: To release the binding, use unbind.

  You can also "rename" the property in the binding by specifying the new name in the to() chain:

  button.bind( 'isEnabled' ).to( command, 'isWorking' );
  

  It is possible to bind more than one property at a time to shorten the code:

  button.bind( 'isEnabled', 'value' ).to( command );
  

  which corresponds to:

  button.bind( 'isEnabled' ).to( command );
  button.bind( 'value' ).to( command );
  

  The binding can include more than one observable, combining multiple data sources in a custom callback:

  button.bind( 'isEnabled' ).to( command, 'isEnabled', ui, 'isVisible',
  	( isCommandEnabled, isUIVisible ) => isCommandEnabled && isUIVisible );
  

  Using a custom callback allows processing the value before passing it to the target property:

  button.bind( 'isEnabled' ).to( command, 'value', value => value === 'heading1' );
  

  It is also possible to bind to the same property in an array of observables. To bind a button to multiple commands (also Observables) so that each and every one of them must be enabled for the button to become enabled, use the following code:

  button.bind( 'isEnabled' ).toMany( [ commandA, commandB, commandC ], 'isEnabled',
  	( isAEnabled, isBEnabled, isCEnabled ) => isAEnabled && isBEnabled && isCEnabled );
  

  Type parameters

  K1

  K2

  Parameters

  bindProperty1 : K1

  Observable property that will be bound to other observable(s).

  bindProperty2 : K2

  Observable property that will be bound to other observable(s).

  Returns

  DualBindChain<K1, ClipboardMarkersUtils[ K1 ], K2, ClipboardMarkersUtils[ K2 ]>

  The bind chain with the to() and toMany() methods.

  Parameters

  id : string

  Unique identifier, equal to the one passed in forceDisabled call.

  Returns

  void

• inherited

  decorate( methodName ) → voidmodule:clipboard/clipboardmarkersutils~ClipboardMarkersUtils#decorate

  See source

  Turns the given methods of this object into event-based ones. This means that the new method will fire an event (named after the method) and the original action will be plugged as a listener to that event.

  Read more in the dedicated guide covering the topic of decorating methods with some additional examples.

  Decorating the method does not change its behavior (it only adds an event), but it allows to modify it later on by listening to the method's event.

  For example, to cancel the method execution the event can be stopped:

  class Foo extends ObservableMixin() {
  	constructor() {
  		super();
  		this.decorate( 'method' );
  	}
  
  	method() {
  		console.log( 'called!' );
  	}
  }
  
  const foo = new Foo();
  foo.on( 'method', ( evt ) => {
  	evt.stop();
  }, { priority: 'high' } );
  
  foo.method(); // Nothing is logged.
  

  Note: The high priority listener has been used to execute this particular callback before the one which calls the original method (which uses the "normal" priority).

  It is also possible to change the returned value:

  foo.on( 'method', ( evt ) => {
  	evt.return = 'Foo!';
  } );
  
  foo.method(); // -> 'Foo'
  

  Finally, it is possible to access and modify the arguments the method is called with:

  method( a, b ) {
  	console.log( `${ a }, ${ b }`  );
  }
  
  // ...
  
  foo.on( 'method', ( evt, args ) => {
  	args[ 0 ] = 3;
  
  	console.log( args[ 1 ] ); // -> 2
  }, { priority: 'high' } );
  
  foo.method( 1, 2 ); // -> '3, 2'
  

  Parameters

  methodName : 'off' | 'on' | 'once' | 'listenTo' | 'stopListening' | 'fire' | 'delegate' | 'stopDelegating' | 'set' | 'bind' | 'unbind' | 'decorate' | 'destroy' | 'isEnabled' | 'editor' | 'forceDisabled' | 'clearForceDisabled' | '_registerMarkerToCopy' | '_copySelectedFragmentWithMarkers' | '_pasteMarkersIntoTransformedElement' | '_pasteFragmentWithMarkers' | '_forceMarkersCopy' | '_isMarkerCopyable' | '_hasMarkerConfiguration' | '_getMarkerClipboardConfig'

  Name of the method to decorate.

  Returns

  void

• inherited

  delegate( events ) → EmitterMixinDelegateChainmodule:clipboard/clipboardmarkersutils~ClipboardMarkersUtils#delegate

  See source

  Delegates selected events to another Emitter. For instance:

  emitterA.delegate( 'eventX' ).to( emitterB );
  emitterA.delegate( 'eventX', 'eventY' ).to( emitterC );
  

  then eventX is delegated (fired by) emitterB and emitterC along with data:

  emitterA.fire( 'eventX', data );
  

  and eventY is delegated (fired by) emitterC along with data:

  emitterA.fire( 'eventY', data );
  

  Parameters

  events : Array<string>

  Event names that will be delegated to another emitter.

  Returns

  EmitterMixinDelegateChain

• inherited

  destroy() → voidmodule:clipboard/clipboardmarkersutils~ClipboardMarkersUtils#destroy

  See source

  Destroys the plugin.

  Note: This method is optional. A plugin instance does not need to have it defined.

  Returns

  void

• inherited

  fire( eventOrInfo, args ) → GetEventInfo<TEvent>[ 'return' ]module:clipboard/clipboardmarkersutils~ClipboardMarkersUtils#fire

  See source

  Fires an event, executing all callbacks registered for it.

  The first parameter passed to callbacks is an EventInfo object, followed by the optional args provided in the fire() method call.

  Type parameters

  TEvent : extends BaseEvent

  The type describing the event. See BaseEvent.

  Parameters

  eventOrInfo : GetNameOrEventInfo<TEvent>

  The name of the event or EventInfo object if event is delegated.

  args : TEvent[ 'args' ]

  Additional arguments to be passed to the callbacks.

  Returns

  GetEventInfo<TEvent>[ 'return' ]

  By default the method returns undefined. However, the return value can be changed by listeners through modification of the evt.return's property (the event info is the first param of every callback).

• inherited

  forceDisabled( id ) → voidmodule:clipboard/clipboardmarkersutils~ClipboardMarkersUtils#forceDisabled

  See source

  Disables the plugin.

  Plugin may be disabled by multiple features or algorithms (at once). When disabling a plugin, unique id should be passed (e.g. feature name). The same identifier should be used when enabling back the plugin. The plugin becomes enabled only after all features enabled it back.

  Disabling and enabling a plugin:

  plugin.isEnabled; // -> true
  plugin.forceDisabled( 'MyFeature' );
  plugin.isEnabled; // -> false
  plugin.clearForceDisabled( 'MyFeature' );
  plugin.isEnabled; // -> true
  

  Plugin disabled by multiple features:

  plugin.forceDisabled( 'MyFeature' );
  plugin.forceDisabled( 'OtherFeature' );
  plugin.clearForceDisabled( 'MyFeature' );
  plugin.isEnabled; // -> false
  plugin.clearForceDisabled( 'OtherFeature' );
  plugin.isEnabled; // -> true
  

  Multiple disabling with the same identifier is redundant:

  plugin.forceDisabled( 'MyFeature' );
  plugin.forceDisabled( 'MyFeature' );
  plugin.clearForceDisabled( 'MyFeature' );
  plugin.isEnabled; // -> true
  

  Note: some plugins or algorithms may have more complex logic when it comes to enabling or disabling certain plugins, so the plugin might be still disabled after clearForceDisabled was used.

  Parameters

  id : string

  Unique identifier for disabling. Use the same id when enabling back the plugin.

  Returns

  void

• inherited

  listenTo( emitter, event, callback, [ options ] ) → voidmodule:clipboard/clipboardmarkersutils~ClipboardMarkersUtils#listenTo:BASE_EMITTER

  See source

  Registers a callback function to be executed when an event is fired in a specific (emitter) object.

  Events can be grouped in namespaces using :. When namespaced event is fired, it additionally fires all callbacks for that namespace.

  // myEmitter.on( ... ) is a shorthand for myEmitter.listenTo( myEmitter, ... ).
  myEmitter.on( 'myGroup', genericCallback );
  myEmitter.on( 'myGroup:myEvent', specificCallback );
  
  // genericCallback is fired.
  myEmitter.fire( 'myGroup' );
  // both genericCallback and specificCallback are fired.
  myEmitter.fire( 'myGroup:myEvent' );
  // genericCallback is fired even though there are no callbacks for "foo".
  myEmitter.fire( 'myGroup:foo' );
  

  An event callback can stop the event and set the return value of the fire method.

  Type parameters

  TEvent : extends BaseEvent

  The type describing the event. See BaseEvent.

  Parameters

  emitter : Emitter

  The object that fires the event.

  event : TEvent[ 'name' ]

  The name of the event.

  Additional options.

  Returns

  void

• inherited

  off( event, callback ) → voidmodule:clipboard/clipboardmarkersutils~ClipboardMarkersUtils#off

  Returns

  void

• inherited

  on( event, callback, [ options ] ) → voidmodule:clipboard/clipboardmarkersutils~ClipboardMarkersUtils#on

  See source

  Registers a callback function to be executed when an event is fired.

  Shorthand for this.listenTo( this, event, callback, options ) (it makes the emitter listen on itself).

  Type parameters

  TEvent : extends BaseEvent

  The type descibing the event. See BaseEvent.

  Type parameters

  TEvent : extends BaseEvent

  The type descibing the event. See BaseEvent.

  Parameters

  event : TEvent[ 'name' ]

  The name of the event.

• inherited

  set( values ) → voidmodule:clipboard/clipboardmarkersutils~ClipboardMarkersUtils#set:OBJECT

  See source

  Creates and sets the value of an observable properties of this object. Such a property becomes a part of the state and is observable.

  It accepts a single object literal containing key/value pairs with properties to be set.

  This method throws the observable-set-cannot-override error if the observable instance already has a property with the given property name. This prevents from mistakenly overriding existing properties and methods, but means that foo.set( 'bar', 1 ) may be slightly slower than foo.bar = 1.

  In TypeScript, those properties should be declared in class using declare keyword. In example:

  public declare myProp1: number;
  public declare myProp2: string;
  
  constructor() {
  	this.set( {
  		'myProp1: 2,
  		'myProp2: 'foo'
  	} );
  }
  

  Parameters

  values : object

  An object with name=>value pairs.

  Returns

  void

• inherited

  _copySelectedFragmentWithMarkers( action, selection, getCopiedFragment ) → DocumentFragmentmodule:clipboard/clipboardmarkersutils~ClipboardMarkersUtils#_copySelectedFragmentWithMarkers

  See source

  Performs copy markers on provided selection and paste it to fragment returned from getCopiedFragment.

  1. Picks all markers in provided selection.
  2. Inserts fake markers to document.
  3. Gets copied selection fragment from document.
  4. Removes fake elements from fragment and document.
  5. Inserts markers in the place of removed fake markers.
  

  Due to selection modification, when inserting items, getCopiedFragment must always operate on `writer.model.document.selection'. Do not use any other custom selection object within callback, as this will lead to out-of-bounds exceptions in rare scenarios.

  Parameters

  action : ClipboardMarkerRestrictedAction

  Type of clipboard action.

  selection : Selection | DocumentSelection

  Selection to be checked.

  getCopiedFragment : ( Writer ) => DocumentFragment

  Callback that performs copy of selection and returns it as fragment.

  Defaults to ...

  Returns

  DocumentFragment

• internal

  _forceMarkersCopy( markerName, executor, config ) → voidmodule:clipboard/clipboardmarkersutils~ClipboardMarkersUtils#_forceMarkersCopy

  See source

  In some situations we have to perform copy on selected fragment with certain markers. This function allows to temporarily bypass restrictions on markers that we want to copy.

  This function executes executor() callback. For the duration of the callback, if the clipboard pipeline is used to copy content, markers with the specified name will be copied to the clipboard as well.

  Parameters

  markerName : string

  Which markers should be copied.

  executor : VoidFunction

  Callback executed.

  config : ClipboardMarkerConfiguration

  Optional configuration flags used to copy (such like partial copy flag).

  Defaults to ...

  Returns

  void

• internal

  _getMarkerClipboardConfig( markerName ) → null | ClipboardMarkerConfigurationmodule:clipboard/clipboardmarkersutils~ClipboardMarkersUtils#_getMarkerClipboardConfig

  See source

  Returns marker's configuration flags passed during registration.

  Parameters

  markerName : string

  Name of marker that should be returned.

  Returns

  null | ClipboardMarkerConfiguration

• internal

  _isMarkerCopyable( markerName, action ) → booleanmodule:clipboard/clipboardmarkersutils~ClipboardMarkersUtils#_isMarkerCopyable

  See source

  Checks if marker can be copied.

  Parameters

  markerName : string

  Name of checked marker.

  action : null | ClipboardMarkerRestrictedAction

  Type of clipboard action. If null then checks only if marker is registered as copyable.

  Returns

  boolean

• internal

  _pasteFragmentWithMarkers( fragment ) → Rangemodule:clipboard/clipboardmarkersutils~ClipboardMarkersUtils#_pasteFragmentWithMarkers

  See source

  Pastes document fragment with markers to document. If duplicateOnPaste is true in marker config then associated markers IDs are regenerated before pasting to avoid markers duplications in content.

  Parameters

  fragment : DocumentFragment

  Document fragment that should contain already processed by pipeline markers.

  Returns

  Range

• internal

  _pasteMarkersIntoTransformedElement( markers, getPastedDocumentElement ) → Elementmodule:clipboard/clipboardmarkersutils~ClipboardMarkersUtils#_pasteMarkersIntoTransformedElement

  See source

  Performs paste of markers on already pasted element.

  1. Inserts fake markers that are present in fragment element (such fragment will be processed in `getPastedDocumentElement`).
  2. Calls `getPastedDocumentElement` and gets element that is inserted into root model.
  3. Removes all fake markers present in transformed element.
  4. Inserts new markers with removed fake markers ranges into pasted fragment.
  

  There are multiple edge cases that have to be considered before calling this function:

  * `markers` are inserted into the same element that must be later transformed inside `getPastedDocumentElement`.
  * Fake marker elements inside `getPastedDocumentElement` can be cloned, but their ranges cannot overlap.
  * If `duplicateOnPaste` is `true` in marker config then associated marker ID is regenerated before pasting.
  

  Parameters

  markers : Map<string, Range> | Record<string, Range>

  Object that maps marker name to corresponding range.

  getPastedDocumentElement : ( Writer ) => Element

  Getter used to get target markers element.

  Returns

  Element

  _insertFakeMarkersIntoSelection( writer, selection, action ) → Record<string, Array<Element>>module:clipboard/clipboardmarkersutils~ClipboardMarkersUtils#_insertFakeMarkersIntoSelection

  See source

  First step of copying markers. It looks for markers intersecting with given selection and inserts $marker elements at positions where document markers start or end. This way $marker elements can be easily copied together with the rest of the content of the selection.

  Parameters

  writer : Writer

  An instance of the model writer.

  selection : Selection | DocumentSelection

  Selection to be checked.

  action : ClipboardMarkerRestrictedAction

  Type of clipboard action.

  Returns

  Record<string, Array<Element>>

  _removeFakeMarkersInsideElement( writer, rootElement ) → Record<string, Range>module:clipboard/clipboardmarkersutils~ClipboardMarkersUtils#_removeFakeMarkersInsideElement

  See source

  Removes all $marker elements from the given document fragment.

  Returns an object where keys are marker names, and values are ranges corresponding to positions where $marker elements were inserted.

  If the document fragment had only one $marker element for given marker (start or end) the other boundary is set automatically (to the end or start of the document fragment, respectively).

  Parameters

  writer : Writer

  An instance of the model writer.

  rootElement : Element | DocumentFragment

  The element to be checked.

  Returns

  Record<string, Range>

  See source

  Fired when a property value is going to be set but is not set yet (before the change event is fired).

  You can control the final value of the property by using the event's return property.

  observable.set( 'prop', 1 );
  
  observable.on<ObservableSetEvent<number>>( 'set:prop', ( evt, propertyName, newValue, oldValue ) => {
  	console.log( `Value is going to be changed from ${ oldValue } to ${ newValue }` );
  	console.log( `Current property value is ${ observable[ propertyName ] }` );
  
  	// Let's override the value.
  	evt.return = 3;
  } );
  
  observable.on<ObservableChangeEvent<number>>( 'change:prop', ( evt, propertyName, newValue, oldValue ) => {
  	console.log( `Value has changed from ${ oldValue } to ${ newValue }` );
  } );
  
  observable.prop = 2; // -> 'Value is going to be changed from 1 to 2'
                       // -> 'Current property value is 1'
                       // -> 'Value has changed from 1 to 3'
