pull-merge

merge sorted pull-streams into one pull stream, while maintaining back-pressure. Source pull streams MUST be in order.

example

var pull = require('pull-stream')
var merge = require('pull-merge')
 
pull(
  merge(pull.values([1, 5, 6]), pull.values([2, 4, 7])),
  pull.collect(function (err, ary) {
    if(err) throw err
 
    console.log(ary)
    //=> [1, 2, 4, 5, 6, 7]
  })
)
 

signatures

merge(left, right, compare?)

return a stream that is the merge of left and right streams. merge pulls a chunk from both left and right and then compares them. compare has the same signature as Array#sort(compare). If the two chunks are compared the same, the chunk from the right stream is taken, but the left chunk is dropped. Otherwise, the lowest chunk is passed to the stream.

merge([streams...], compare?)

Merge a collection of steams. This calls the first signature recursively.
