make-stream.js

import stream from 'stream'

let Transform = stream.Transform

export default function makeStream(transform, flush) {
	let stream = new Transform({ objectMode: true })
	let push = stream.push.bind(stream)
	stream._transform = (file, enc, cb) => transform(file, push, cb)
	if (flush) {
		stream._flush = cb => flush(push, cb)
	}
