Documentation

Overview

Package jsonpath reads one value out of a decoded JSON document by a path an operator writes: "$" for the document itself, ".name" or "['name']" for an object member, and "[n]" for an array element, as in "$.data.events" or "$.contact['id']" (#1870).

It is the subset of JSONPath that addresses one value. There are no wildcards, filters or recursive descent: a webhook source uses a path to find its event array, and an event's id, type and key, and each of those is one place in the document.

Functions

func Scalar 

func Scalar(v any) string

Scalar renders a looked-up value as the text a column stores: a string as itself, a number as written, true and false as words, null as empty, and an object or array as its compact JSON.

Types

type Path 

type Path struct {
	// contains filtered or unexported fields
}

Path is a parsed path.

func Parse 

func Parse(text string) (Path, error)

Parse reads a path. The leading "$" may be omitted: "data.id" is "$.data.id".

func (Path) Lookup 

func (p Path) Lookup(doc any) (any, bool)

Lookup returns the value the path addresses in doc, and false when any step is missing or of the wrong kind.

func (Path) String 

func (p Path) String() string

String is the path as it was written.
