pull-regenerate v0.0.0

pull-regenerate

A source that masks other sources over its lifetime.

Install

npm i pull-regenerate

Usage

regenerate(initial, swap)

Create a pull-stream source that masks other sources over its lifetime. Instead of aborting when the initial stream aborts, it uses a new source returned from swap(nth, abort), where nth is the amount of times it has swapped and abort is a function that lets you actually abort.

The stream also has abort() and set(stream) methods attached.

let source = regenerate(
    values([ 1, 2, 3 ]),
    (nth, abort) => {
        if (nth > 10) return abort()
        return values([ i + 1, i + 2, i + 3 ])
    }
)

if (something) {
    source.set(
        values([0, 1, 2, 3])
    )
} else if (otherthing) {
    source.abort()
}

pull(
    source,
    collect((err, data) => {
        console.log(data)
    })
)
