func Generate ¶

func Generate(
	parsed *diff.ParsedDiff, selections []*diff.FileSelection,
) ([]byte, error)

Generate creates a patch containing only the selected lines. The patch can be applied with `git apply --cached`.

Every selection must contribute at least one line. A selection naming a path or a range with no changes fails the whole patch rather than being dropped from it, so a caller that mistypes one of several selections is told, instead of being handed a patch that silently stages less than it asked for.

func GenerateForFile ¶

func GenerateForFile(file *diff.FileDiff) []byte

GenerateForFile creates a patch for a single file with all its changes.

func GenerateForHunk ¶

func GenerateForHunk(file *diff.FileDiff, hunk *diff.Hunk) []byte

GenerateForHunk creates a patch for a single hunk.
