Path
Path arrays are a list of indexes that describe a node's exact position in a Slate node tree. Although they are usually relative to the root Editor object, they can be relative to any Node object.

Static methods

Retrieval methods

Path.ancestors(path: Path, options: { reverse?: boolean } = {}) => Path[]

Get a list of ancestor paths for a given path.
The paths are sorted from deepest to shallowest ancestor. However, if the reverse: true option is passed, they are reversed.

Path.common(path: Path, another: Path) => Path

Get the common ancestor path of two paths.

Path.compare(path: Path, another: Path) => -1 | 0 | 1

Compare a path to another, returning an integer indicating whether the path was before, at, or after the other.
Note: Two paths of unequal length can still receive a 0 result if one is directly above or below the other. If you want exact matching, use [[Path.equals]] instead.

Path.levels(path: Path, options?) => Path[]

Get a list of paths at every level down to a path. Note: this is the same as Path.ancestors, but includes the path itself.
The paths are sorted from shallowest to deepest. However, if the reverse: true option is passed, they are reversed.
Options: {reverse?: boolean}

Path.next(path: Path) => Path

Given a path, gets the path to the next sibling node. The method does not ensure that the returned Path is valid in the document.

Path.parent(path: Path) => Path

Given a path, return a new path referring to the parent node above it. If the path argument is equal to [], throws an error.

Path.previous(path: Path) => Path

Given a path, get the path to the previous sibling node. The method will throw an error if there are no previous siblings (e.g. if the Path is currently [1, 0], the previous path would be [1, -1] which is illegal and will throw an error).

Path.relative(path: Path, ancestor: Path) => Path

Given two paths, one that is an ancestor to the other, returns the relative path from the ancestor argument to the path argument. If the ancestor path is not actually an ancestor or equal to the path argument, throws an error.

Check methods

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

Path.endsAfter(path: Path, another: Path) => boolean

Check if a path ends after one of the indexes in another.

Path.endsAt(path: Path, another: Path) => boolean

Check if a path ends at one of the indexes in another.

Path.endsBefore(path: Path, another: Path) => boolean

Check if a path ends before one of the indexes in another.

Path.equals(path: Path, another: Path) => boolean

Check if a path is exactly equal to another.

Path.hasPrevious(path: Path) => boolean

Check if the path of previous sibling node exists

Path.isAfter(path: Path, another: Path) => boolean

Check if a path is after another.

Path.isAncestor(path: Path, another: Path) => boolean

Check if a path is an ancestor of another.

Path.isBefore(path: Path, another: Path) => boolean

Check if a path is before another.

Path.isChild(path: Path, another: Path) => boolean

Check if a path is a child of another.

Path.isCommon(path: Path, another: Path) => boolean

Check if a path is equal to or an ancestor of another.

Path.isDescendant(path: Path, another: Path) => boolean

Check if a path is a descendant of another.

Path.isParent(path: Path, another: Path) => boolean

Check if a path is the parent of another.

Path.isPath(value: any) => value is Path

Check is a value implements the Path interface.

Path.isSibling(path: Path, another: Path) => boolean

Check if a path is a sibling of another.

Transform method

Path.transform(path: Path, operation: Operation, options?) => Path | null

Transform a path by an operation.
Options: { affinity?: 'forward' | 'backward' | null }
