Path API
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.
type Path = number[]
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 shallowest to deepest 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 }
