where are the non pretty options?

I see these:

https://godocs.io/github.com/sergi/go-diff/diffmatchpatch#DiffMatchPatch.DiffPrettyText

how to create a diff without color?

looks like it would just be like this:

func DiffText(diffs []Diff) string {
   var buf strings.Builder
   for _, diff := range diffs {
      buf.WriteString(diff.Text)
   }
   return buf.String()
}

What output do you get from that? I just get the same text as the colored output without color. Which is meaningless because there are no + or - or any symbols to tell which text is added/removed in the diff:

text1 := `abc
x123
def
feg`

text2 := `abc
deg
feg
ooo`

diffs := dmp.DiffMain(text1, text2, false)

With the code above I get this output:

abc
x123
defg
feg
ooo

good catch, looks like this would do it:

func diff_text(diffs []Diff) string {
   var b strings.Builder
   for _, diff := range diffs {
      switch diff.Type {
      case DiffInsert:
         b.WriteByte('+')
         b.WriteString(diff.Text)
      case DiffDelete:
         b.WriteByte('-')
         b.WriteString(diff.Text)
      case DiffEqual:
         b.WriteString(diff.Text)
      }
   }
   return b.String()
}

@sergi I miss that feature, too

btw, I use that package now. It has a simple way to get a unified diff: https://pkg.go.dev/github.com/akedrou/textdiff#Unified
