Types

type LValue

type LValue []string

LValue represents a field (path) that can be written to.

func (LValue) Delete

func (a LValue) Delete() Statements

Delete removes a (potentially nested) key from its parent maps, if that key exists.

func (LValue) DeleteIf

func (a LValue) DeleteIf(cond Value) Statements

Delete removes a (potentially nested) key from its parent maps, if that key exists.

func (LValue) IsPresent

func (a LValue) IsPresent() Value

IsPresent returns true if the field is recursively present (with any value)
