Functions

func Diff

func Diff(x, y cue.Value) (Kind, *EditScript)

Diff is a shorthand for Schema.Diff.

func Print

func Print(w io.Writer, es *EditScript) error

Print the differences between two structs represented by an edit script.

Types

type Edit

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

Edit represents a single operation within an edit-script.

func (Edit) Kind

func (e Edit) Kind() Kind

func (Edit) XPos

func (e Edit) XPos() int

func (Edit) YPos

func (e Edit) YPos() int

type EditScript

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

EditScript represents the series of differences between two CUE values. x and y must be either both list or struct.

func (*EditScript) LabelX

func (es *EditScript) LabelX(i int) string

Label returns a string representation of the label.

func (*EditScript) LabelY

func (es *EditScript) LabelY(i int) string

func (*EditScript) Len

func (es *EditScript) Len() int

Len returns the number of edits.

func (*EditScript) ValueX

func (es *EditScript) ValueX(i int) (v cue.Value)

ValueX returns the value of X involved at step i.

func (*EditScript) ValueY

func (es *EditScript) ValueY(i int) (v cue.Value)

ValueY returns the value of Y involved at step i.

type Kind

type Kind uint8

Kind identifies the kind of operation of an edit script.

const (
	// Identity indicates that a value pair is identical in both list X and Y.
	Identity Kind = iota
	// UniqueX indicates that a value only exists in X and not Y.
	UniqueX
	// UniqueY indicates that a value only exists in Y and not X.
	UniqueY
	// Modified indicates that a value pair is a modification of each other.
	Modified
)

type Profile

type Profile struct {
	Concrete bool
}

Profile configures a diff operation.

func (*Profile) Diff

func (p *Profile) Diff(x, y cue.Value) (Kind, *EditScript)

Diff returns an edit script representing the difference between x and y.
