Functions

func UnifiedDiff 

func UnifiedDiff(oldText, newText, path string, contextLines int) string

func UnifiedDiffExact 

func UnifiedDiffExact(oldText, newText, path string, contextLines int) string

UnifiedDiffExact emits a line diff without normalizing BOMs or line endings. It is used when the byte-level replacement itself is the operation being reported, rather than a normalized text edit.

Types

type AmbiguityError 

type AmbiguityError struct {
	Count int
	Lines []int
}

func (*AmbiguityError) Error 

func (e *AmbiguityError) Error() string

func (*AmbiguityError) Unwrap 

func (e *AmbiguityError) Unwrap() error

type Range
