Types ¶

type Differ ¶

type Differ struct {
	Cmd       string   // command
	MultiDiff bool     // diff accepts list of multiple pairs
	Args      []string // accumulated arguments
}

A Differ describes how to invoke diff.

func Find ¶

func Find() (*Differ, bool)

Find returns the differ to use, using various environment variables.

func (*Differ) Run ¶

func (d *Differ) Run() error

Run runs any pending diffs. For a single-pair diff program, Show already ran diff; Run is a no-op. For a multi-pair diff program, Run displays the diffs queued by Show.

func (*Differ) Show ¶

func (d *Differ) Show(old, new string) error

Show diffs old and new. For a single-pair diff program, Show runs the diff program before returning. For a multi-pair diff program, Show records the pair for later use by Run.
