Functions ¶

func Coalesce ¶

func Coalesce(spec *Config, data []byte) ([]byte, error)

Coalesce checks multiple keys and returns the first matching key found in raw []byte.

func Concat ¶

func Concat(spec *Config, data []byte) ([]byte, error)

Concat combines any specified fields and literal strings into a single string value with raw []byte.

func Default ¶

func Default(spec *Config, data []byte) ([]byte, error)

Default sets specific value(s) in output json in raw []byte.

func Delete ¶

func Delete(spec *Config, data []byte) ([]byte, error)

Delete deletes keys in-place from the provided data if they exist keys are specified in an array under "keys" in the spec.

func Extract ¶

func Extract(spec *Config, data []byte) ([]byte, error)

Extract returns the specified path as the top-level object in raw []byte.

func HandleUnquotedStrings ¶

func HandleUnquotedStrings(value []byte, dt jsonparser.ValueType) []byte

jsonparser strips quotes from returned strings, this adds them back

func Pass ¶

func Pass(spec *Config, data []byte) ([]byte, error)

Pass performs no manipulation of the passed-in data. It is useful for testing/default behavior.

func Shift ¶

func Shift(spec *Config, data []byte) ([]byte, error)

Shift moves values from one provided json path to another in raw []byte.

func Timestamp ¶

func Timestamp(spec *Config, data []byte) ([]byte, error)

Timestamp parses and formats timestamp strings using the golang syntax

func UUID ¶

func UUID(spec *Config, data []byte) ([]byte, error)

UUID tries to generate a UUID based on spec components

Types ¶

type Config ¶

type Config struct {
	Spec         *map[string]interface{} `json:"spec"`
	Require      bool                    `json:"require,omitempty"`
	InPlace      bool                    `json:"inplace,omitempty"`
	KeySeparator string                  `json:"keySeparator"`
}

Config contains the options that dictate the behavior of a transform. The internal `spec` object can be an arbitrary json configuration for the transform.
