func MakeLineDiffsFromDMP

func MakeLineDiffsFromDMP(diffs []diffmatchpatch.Diff) []LineDiff

In order to make line diffs from github.com/seri/diffmatchpatch, you can make by steps shown below:

// Computing a line-mode diff by github.com/seri/diffmatchpatch
// @see https://github.com/google/diff-match-patch/wiki/Line-or-Word-Diffs
dmp := diffmatchpatch.New()
runes1, runes2, lineArray := dmp.DiffLinesToRunes(text1, text2)
diffs := dmp.DiffMainRunes(runes1, runes2, false)
diffs = dmp.DiffCharsToLines(diffs, lineArray)

// Make `[]LineDiff` from `[]diffmatchpatch.Diff`
lineDiffs := difffmt.MakeLineDiffsFromDMP(diffs)
