TrackChangesEditing
Provides editing part of the track changes plugin.
Properties
activeMarkers : Array<string>module:track-changes/trackchangesediting~TrackChangesEditing#activeMarkersList of names of active (highlighted) markers.
adapter : null | TrackChangesAdaptermodule:track-changes/trackchangesediting~TrackChangesEditing#adapterParameters
adapter : null | TrackChangesAdapter
module:track-changes/trackchangesediting~TrackChangesEditing#descriptionFactoryDescriptions factory which generates descriptions for the suggestions created by the track changes plugin.
module:track-changes/trackchangesediting~TrackChangesEditing#editorThe editor instance.
Note that most editors implement the
uiproperty. 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:
isEnabled : booleanmodule:track-changes/trackchangesediting~TrackChangesEditing#isEnabledFlag 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;Copy codeYou can also use
forceDisabledmethod.module:track-changes/trackchangesediting~TrackChangesEditing#trackChangesCommandReference to command that turns the track changes mode on and off.

bind( bindProperty1, bindProperty2 ) → ObservableDualBindChain<K1, TrackChangesEditing[ K1 ], K2, TrackChangesEditing[ K2 ]>inheritedmodule:track-changes/trackchangesediting~TrackChangesEditing#bind:DUAL_BINDBinds observable properties to other objects implementing the
Observableinterface.Read more in the dedicated guide covering the topic of property bindings with some additional examples.
Consider two objects: a
buttonand an associatedcommand(bothObservable).A simple property binding could be as follows:
button.bind( 'isEnabled' ).to( command, 'isEnabled' );Copy codeor even shorter:
button.bind( 'isEnabled' ).to( command );Copy codewhich works in the following way:
button.isEnabledinstantly equalscommand.isEnabled,- whenever
command.isEnabledchanges,button.isEnabledwill 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' );Copy codeIt is possible to bind more than one property at a time to shorten the code:
button.bind( 'isEnabled', 'value' ).to( command );Copy codewhich corresponds to:
button.bind( 'isEnabled' ).to( command ); button.bind( 'value' ).to( command );Copy codeThe 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 );Copy codeUsing a custom callback allows processing the value before passing it to the target property:
button.bind( 'isEnabled' ).to( command, 'value', value => value === 'heading1' );Copy codeIt is also possible to bind to the same property in an array of observables. To bind a
buttonto multiple commands (alsoObservables) 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 );Copy codeType parameters

clearForceDisabled( id ) → voidinheritedmodule:track-changes/trackchangesediting~TrackChangesEditing#clearForceDisabledClears forced disable previously set through
forceDisabled. SeeforceDisabled.Parameters
id : stringUnique identifier, equal to the one passed in
forceDisabledcall.
Returns
void
decorate( methodName ) → voidinheritedmodule:track-changes/trackchangesediting~TrackChangesEditing#decorateTurns 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.Copy codeNote: 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'Copy codeFinally, 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'Copy codeParameters

Returns
void
discardSuggestion( suggestion ) → voidmodule:track-changes/trackchangesediting~TrackChangesEditing#discardSuggestionenableCommand( commandName, [ callback ] ) → voidmodule:track-changes/trackchangesediting~TrackChangesEditing#enableCommandEnables command with given
commandNamein track changes mode.When a command gets enabled in track changes mode, its original
execute()method is overwritten by providedcallback()function. Thecallback()should provide alternative logic to be executed instead.The
callback()function is passed one or more parameters:- the first parameter is
executeCommand(), a function that upon calling will fire the originalexecute()method, - then, all the parameters passed to original
execute()call are passed.
Using those parameters it is possible to call the original command in the
callback()(or skip it) and also do something before and/or after that call.If
callbackis not set then the command will work the same both when track changes is on and off.See the Integrating track changes with custom features guide to learn more about enabling your feature in the suggestion mode.
Parameters
commandName : string[ callback ] : Function
Returns
void
- the first parameter is
enableDefaultAttributesIntegration( commandName ) → voidmodule:track-changes/trackchangesediting~TrackChangesEditing#enableDefaultAttributesIntegrationEnables default attributes suggestions integration for given command.
Parameters
commandName : stringName of the command to integrate.
Returns
void
fire( eventOrInfo, args ) → GetEventInfo<TEvent>[ 'return' ]inheritedmodule:track-changes/trackchangesediting~TrackChangesEditing#fireFires an event, executing all callbacks registered for it.
The first parameter passed to callbacks is an
EventInfoobject, followed by the optionalargsprovided in thefire()method call.Type parameters
Parameters
eventOrInfo : GetNameOrEventInfo<TEvent>The name of the event or
EventInfoobject 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 theevt.return's property (the event info is the first param of every callback).
forceDefaultExecution( callback ) → unknownmodule:track-changes/trackchangesediting~TrackChangesEditing#forceDefaultExecutionTemporarily disable track changes to accept or discard a suggestion without intercepting original calls.
Parameters
callback : Function
Returns
unknown
forceDisabled( id ) → voidinheritedmodule:track-changes/trackchangesediting~TrackChangesEditing#forceDisabledDisables 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.

listenTo( emitter, event, callback, [ options ] ) → voidinheritedmodule:track-changes/trackchangesediting~TrackChangesEditing#listenTo:BASE_EMITTERRegisters 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' );Copy codeAn event callback can stop the event and set the return value of the
firemethod.Type parameters
Parameters
emitter : EmitterThe object that fires the event.
event : TEvent[ 'name' ]The name of the event.
callback : GetCallback<TEvent>The function to be called on event.
[ options ] : GetCallbackOptions<TEvent>Additional options.
Returns

markAttributeChange( range, key, oldValue, newValue, attributes = { attributes.groupId, attributes.[key: string] } ) → Array<Suggestion>module:track-changes/trackchangesediting~TrackChangesEditing#markAttributeChangeMarks a single-range attribute suggestion on the given
range.Note: all nodes in the given
rangemust have the same current value ofkeyattribute.Note: if a block attribute is marked,
rangeshould include only a single model element.attributesis a required value and must includegroupId: stringproperty. The group id is used to group attribute suggestions together. All suggestions with the samegroupIdwill be put into one suggestion chain. By default, all attribute suggestions created during the same batch have the samegroupId.It's possible that more than one suggestion will be created by this method if there are already suggestions with the same
keybut a differentoldValueintersecting with the givenrange.It is guaranteed that there will be no "conflicting" suggestions, that is, there will be no two intersecting suggestions for the same attribute
key. If there is a conflicting suggestion, it will be partially or fully replaced by a new suggestion.This method should be used in
callback()inTrackChangesEditing#enableCommandto inform the track changes plugin about a suggestion that happened.Always call this method inside
model.change()ormodel.enqueueChange()block to ensure that all operations performed by this method are bound with one undo step.See Integrating track changes with custom features guide to learn more about enabling your feature in the suggestion mode.
Parameters
range : ModelRangeRange for which the attribute has changed.
key : stringKey of the attribute that changed.
oldValue : unknownPrevious value of the attribute.
newValue : unknownNew value of the attribute.
attributes : objectSuggestion attributes. Must include
groupId.Propertiesattributes.groupId : stringattributes.[key: string] : any
Returns
Array<Suggestion>
markBlockFormat( elementOrRange, formatData, affectedElements, subType, attributes ) → null | Suggestionmodule:track-changes/trackchangesediting~TrackChangesEditing#markBlockFormatMarks a block format suggestion on the given
range.Block format suggestions are directly coupled with editor commands and represent a command execution on the given range or element.
This type of format suggestion is suitable for formatting (attribute) changes on block elements. Changes like resizing image, applying block quote or changing header type use this type of format suggestion.
Pass element if the suggestion should be marked exactly on that element. This is suitable if the command modifies exactly given element (for example, changes an attribute of that element). If such element is split, an additional suggestion is created for the new element:
[<paragraph>Foobar]</paragraph> --> [<paragraph>Foo]</paragraph>[<paragraph>bar]</paragraph>Copy codePass range for suggestions representing commands that can be executed on multiple blocks at once. This is suitable for commands which modifies all the block elements found in given range (those commands usually operate on selection ranges). This creates only one suggestion for the whole range and do not create additional suggestions if blocks in the range are split:
[<paragraph>Foobar]</paragraph> --> [<paragraph>Foo</paragraph><paragraph>Bar]</paragraph>Copy codeExample of marking block format suggestion on an element:
trackChangesPlugin.markBlockFormat( paragraphElement, { commandName: 'heading', commandParams: [ { value: 'heading1' } ], formatGroupId: 'blockName' } );Copy codeExample of marking block format suggestion on a range:
plugin.markBlockFormat( selectionRange, { commandName: 'blockQuote', commandParams: [ { forceValue: true } ] } );Copy codeIf you pass a range, it should start before the first element to change and end:
- for blocks (like paragraph, list item, heading, etc.): at the end of the last element to change,
- for objects (like image, table, media embed, etc.): after the last element to change.
[<paragraph>Foo</paragraph><paragraph>Bar]</paragraph><paragraph>Xyz</paragraph> [<paragraph>Foo</paragraph><imageBlock src="foo.jpg"></imageBlock>]<paragraph>Xyz</paragraph>Copy codeThis method should be used in
callback()inTrackChangesEditing#enableCommandto inform the track changes plugin about a suggestion that happened.Always call this method inside
model.change()ormodel.enqueueChange()block to ensure that all operations performed by this method are bound with one undo step.When a format suggestion is accepted the command is executed based on parameters passed in
formatData.If a block format suggestion is marked inside the local user's insertion suggestion, the change is applied directly and no suggestion is created. Note that this does not support partial intersections with insertion suggestions (as opposed to inline format suggestions).
If possible, the new suggestion will be joined with an existing suggestion (of the same type). This happens only if the suggestions are created by the same user and have similar attributes (i.e. passed
attributesdo not conflict with the existing suggestion).See the Integrating track changes with custom features guide to learn more about enabling your feature in the suggestion mode.
Parameters
elementOrRange : ModelElement | ModelRangeElement or range on which the change happened.
formatData : SuggestionFormatDataCommand parameters and additional suggestion parameters.
affectedElements : Array<ModelElement>Elements (other than
elementOrRange) that are also affected by the command execution. This parameter is used when the effect of the command execution is larger thanelementOrRange. It is used when determining whether the change should be applied directly or if the suggestion should be created.Defaults to
[]subType : null | stringSuggestion
subTypeto set. If not set (which is the default and recommended use) the sub type value is a string hash generated fromformatData. This guarantees that all block format suggestions that perform the same changes have the same sub types (and can be properly handled).Defaults to

markInlineFormat( range, formatData, subType, attributes ) → nullmodule:track-changes/trackchangesediting~TrackChangesEditing#markInlineFormatMarks an inline format suggestion on the given
range.This type of format suggestion is suitable for formatting (attribute) changes on inline elements and text. Changes like adding bold or setting a link use this type of format suggestion.
Inline format suggestions are directly coupled with editor commands and represent a command execution on given
range.trackChangesPlugin.markInlineFormat( formattedRange, { commandName: 'bold', commandParams: [ { forceValue: true } ] } ); trackChangesPlugin.markInlineFormat( formattedRange, formatData, 'customSubType' );Copy codeThis method should be used in

formatData.If an inline format suggestion is marked inside the local user's insertion suggestion, the change is applied directly and no suggestion is created. This supports partial intersections with insertion suggestions.
If possible, the new suggestion will be joined with an existing suggestion (of the same type). This happens only if the suggestions are created by the same user and have similar attributes (i.e. passed
attributesdo not conflict with the existing suggestion).See the Integrating track changes with custom features guide to learn more about enabling your feature in the suggestion mode.
Parameters

markMultiRangeBlockFormat( elementsOrRanges, formatData, affectedElements, subType, attributes ) → null | Suggestionmodule:track-changes/trackchangesediting~TrackChangesEditing#markMultiRangeBlockFormatMarks a multi-range block format suggestion on given
elements.See
TrackChangesEditing#markBlockFormat()to learn more about block format suggestions. Note that this method can be used only on elements (not on ranges).This method is useful for creating a format suggestion on multiple elements which are not siblings, so one range cannot be used.
This method should be used in

markMultiRangeDeletion( ranges, subType, attributes ) → null | Suggestionmodule:track-changes/trackchangesediting~TrackChangesEditing#markMultiRangeDeletionMarks a multi-range deletion suggestion spanning over given
ranges.Each range of a multi-range deletion suggestion should contain exactly one element and should not be created on a text content.
If the
rangesto mark contain or are contained in insertion suggestions created by the local user, those insertion suggestions may be removed together with their content.trackChangesPlugin.markMultiRangeDeletion( deletedRanges ); trackChangesPlugin.markMultiRangeDeletion( deletedRanges, 'customDeletion' );Copy codeThis method should be used in
callback()inTrackChangesEditing#enableCommandto inform the track changes plugin about a suggestion that happened.Always call this method inside
model.change()ormodel.enqueueChange()block to ensure that all operations performed by this method are bound with one undo step.If possible, the new suggestion will be joined with an existing suggestion (of the same type). This happens only if the suggestions are created by the same user and have similar attributes (i.e. passed
attributesdo not conflict with the existing suggestion).See the Integrating track changes with custom features guide to learn more about enabling your feature in the suggestion mode.
Parameters
ranges : Array<ModelRange>Ranges which should be marked as deletion suggestion.
subType : stringSuggestion
subTypeto set. Only suggestions with the same sub type will be joined.Defaults to
'multi'attributes : Record<string, unknown>Custom suggestion attributes.
Defaults to
{}
Returns
null | SuggestionSuggestion created or expanded as a result of execution of this method.
markMultiRangeInsertion( ranges, subType, attributes ) → Suggestionmodule:track-changes/trackchangesediting~TrackChangesEditing#markMultiRangeInsertionMarks a multi-range insertion suggestion spanning over given

off( event, callback ) → voidinheritedmodule:track-changes/trackchangesediting~TrackChangesEditing#offStops executing the callback on the given event. Shorthand for
this.stopListening( this, event, callback ).Parameters
event : stringThe name of the event.
callback : FunctionThe function to stop being called.
Returns
void
on( event, callback, [ options ] ) → voidinheritedmodule:track-changes/trackchangesediting~TrackChangesEditing#onRegisters 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
Parameters
event : TEvent[ 'name' ]The name of the event.
callback : GetCallback<TEvent>The function to be called on event.
[ options ] : GetCallbackOptions<TEvent>Additional options.
Returns
void
once( event, callback, [ options ] ) → voidinheritedmodule:track-changes/trackchangesediting~TrackChangesEditing#onceRegisters a callback function to be executed on the next time the event is fired only. This is similar to calling
onfollowed byoffin the callback.Type parameters
Parameters
event : TEvent[ 'name' ]The name of the event.
callback : GetCallback<TEvent>The function to be called on event.
[ options ] : GetCallbackOptions<TEvent>Additional options.
Returns
void
recordAttributeChanges( callback ) → voidmodule:track-changes/trackchangesediting~TrackChangesEditing#recordAttributeChangesExecutes given callback and then finds all attribute and rename changes that have been made during that callback. For all these changes, creates proper attribute suggestions. Additionally cleans up existing, conflicting attribute suggestions if they intersect with the newly created suggestions.
Parameters
callback : () => voidFunction to call and check for attribute and rename changes. Usually this executes an editor command.
Returns
void
registerBlockAttribute( attributeKey ) → voidmodule:track-changes/trackchangesediting~TrackChangesEditing#registerBlockAttributeRegisters given attribute key for tracking as a block attribute (i.e. an attribute made on a block element).
Parameters
attributeKey : string
Returns
void
registerInlineAttribute( attributeKey ) → voidmodule:track-changes/trackchangesediting~TrackChangesEditing#registerInlineAttributeRegisters given attribute key for tracking as an inline attribute (i.e. an attribute made on an inline element).
Parameters
attributeKey : string
Returns
void
set( values ) → voidinheritedmodule:track-changes/trackchangesediting~TrackChangesEditing#set:OBJECTCreates 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-overrideerror if the observable instance already has a property with the given property name. This prevents from mistakenly overriding existing properties and methods, but means thatfoo.set( 'bar', 1 )may be slightly slower thanfoo.bar = 1.In TypeScript, those properties should be declared in class using
declarekeyword. In example:public declare myProp1: number; public declare myProp2: string; constructor() { this.set( { 'myProp1: 2, 'myProp2: 'foo' } ); }Copy codeParameters
values : objectAn object with
name=>valuepairs.
Returns
void
set( name, value ) → voidinheritedmodule:track-changes/trackchangesediting~TrackChangesEditing#set:KEY_VALUECreates and sets the value of an observable property of this object. Such a property becomes a part of the state and is observable.

startTrackingSession( [ id ] ) → null | stringmodule:track-changes/trackchangesediting~TrackChangesEditing#startTrackingSessionStarts a new tracking session, stopping all newly created suggestions from being joined with the previously existing ones, even if they meet the merging criteria. It returns an id that can be later used to continue the session by calling this method with said id as an argument.
Parameters
[ id ] : null | string
Returns
null | string
stopDelegating( [ event ], [ emitter ] ) → voidinheritedmodule:track-changes/trackchangesediting~TrackChangesEditing#stopDelegatingStops delegating events. It can be used at different levels:
- To stop delegating all events.

Returns
void
stopListening( [ emitter ], [ event ], [ callback ] ) → voidinheritedmodule:track-changes/trackchangesediting~TrackChangesEditing#stopListening:BASE_STOPStops listening for events. It can be used at different levels:
- To stop listening to a specific callback.
- To stop listening to a specific event.
- To stop listening to all events fired by a specific object.
- To stop listening to all events fired by all objects.
