Expected behaviour for multiline formats

[homonecloco]

In case that a "unit" of information is contained in more than one line, what should be done in the readline method? Intuitively, I would say read the whole unit.
R.

Buffer the current unit in the instance.
Have a look at biojs-io-matrix

var mParser = new MParser();
mParser.parseLine("A 1");
mParser.parseLine("B 2 3");
var matrix = mParser.buildMatrix();

In the future we should also use streams and there the pattern gets more obvious and easier to understand. However atm I am a bit worried about the increased size when I add them (#1).

input.on("chunk", function(d){
  if(d = "--"){
    out.write(this.buffer);
   this.buffer = [];
  }else{
   buffer.push(JSON.parse(d)); // adding the current line to the buffer
  }
})

input.on("end", function(d){
  out.write(this.buffer);
})
