func Capture ¶

func Capture(writers ...io.Writer) gloo.Command[[]byte, []byte]

Capture returns a Command that passes every line through unchanged while writing it (newline-terminated) to each provided writer. Place it anywhere in a pipeline to capture the stream into one or more buffers without altering it; with no writers it is a pass-through.

Capturing is a side-effect, so Capture is a Tap: the line continues downstream after being written.
