get :: Path -> JSON -> Maybe JSON

Attempts to get the value at the path in a JSON document.

print :: Path -> String

Prints the path as a basic JSONPath expression.

extend :: Path -> Path -> Path

Extends the tip of the first path with the second path.

For example, $.data[0] extended with $.info.title would result in $.data[0].info.title.

findCommonPrefix :: Path -> Path -> Path

Finds the common prefix of two paths. If they have nothing in common the result will be the root.

stripPrefix :: Path -> Path -> Maybe Path

Attempts to strip the first path from the start of the second path. Nothing is returned if the second path does not start with the prefix.

For example, stripping a prefix of $.data[0] from $.data[0].info.title would result in $.info.title.
