Reference

func Diff(oldText, newText string, diffType DiffType) Result

It returns diff information from oldText/newText. diffType should be WordByWord or LineByLine.

Result.Unified(oldDocPath, newDocPath string, keepLines int, theme map[Tag]string) string

keepLines is like diff -U n. No changed lines count around diffs.

theme is a style text to create string representation. There is GooKitColorTheme and HTMLTheme. GooKitColorTheme has tags of github.com/gookit/color.

Result.Format(theme map[Tag]string) string

It doesn't omit unchanged line blocks instead of Unified().

Result.String() sring
