func GenerateDiff ¶

func GenerateDiff(specRaw string, patches []schema.Patch, w io.Writer) string

GenerateDiff converts schema.Patch entries into a unified diff string suitable for writing to --patch-out. Patches that cannot be located in the spec are skipped with a warning written to w (may be nil). Both before and after are normalized before diffing to avoid spurious whitespace diffs.
