Method PathFrom

tree/nodebase.go:250–263

PathFrom returns the path to this node from the given parent node, using [Node.Name]s separated by / delimeters. Any existing / characters in names are escaped to \\ The paths that it returns exclude the name of the parent and the leading slash; for example, in the tree a/b/c/d/e, the result of d.P

(parent Node)

// automatically gets the [NodeBase.This] version of the given parent,
// so a base type can be passed in without manually accessing [NodeBase.This].
func (n *NodeBase) PathFrom(parent Node) string {
	if n.This == parent {
		return ""
	}
	// critical to get `This`
	parent = parent.AsTree().This
	// we bail a level below the parent so it isn't in the path
	if n.Parent == nil || n.Parent == parent {
		return EscapePathName(n.Name)
	}
	ppath := n.Parent.AsTree().PathFrom(parent)
	return ppath + "/" + EscapePathName(n.Name)

}

// FindPath returns the node at the given path from this node.
// FindPath only works correctly when names are unique.
