Range

Range objects are a set of points that refer to a specific span of a Slate document. They can define a span inside a single node or they can span across multiple nodes. The editor's selection is stored as a range.

interface Range {
anchor: Point
focus: Point
}

Static methods

Retrieval methods

Range.edges(range: Range, options?): [Point, Point]

Get the start and end points of a range, in the order in which they appear in the document.

Options: {reverse?: boolean}

Range.end(range: Range): Point

Get the end point of a range.

Range.intersection(range: Range, another: Range): Range | null

Get the intersection of one range with another.

Range.points(range: Range): Generator<PointEntry>

Iterate through all the point entries in a range.

Range.start(range: Range): Point

Get the start point of a range

Check methods

Check some attribute of a Range. Always returns a boolean.

Range.equals(range: Range, another: Range): boolean

Check if a range is exactly equal to another.

Range.includes(range: Range, target: Path | Point | Range): boolean

Check if a range includes a path, a point, or part of another range.

Range.isBackward(range: Range): boolean

Check if a range is backward, meaning that its anchor point appears after its focus point in the document.

Range.isCollapsed(range: Range): boolean

Check if a range is collapsed, meaning that both its anchor and focus points refer to the exact same position in the document.

Range.isExpanded(range: Range): boolean

Check if a range is expanded. This is the opposite of Range.isCollapsed and is provided for legibility.

Range.isForward(range: Range): boolean

Check if a range is forward. This is the opposite of Range.isBackward and is provided for legibility.

Range.isRange(value: any): value is Range

Check if a value implements the Range interface.

Transform methods

Range.transform(range: Range, op: Operation, options): Range | null

Transform a range by an op.

Options: {affinity: 'forward' | 'backward' | 'outward' | 'inward' | null}
