[SOLVED] Node.js - Javascript - Parsing file into nested objects

Node.js - Javascript - Parsing file into nested objects

I'm new to Javascript and am having trouble with a function I wrote. I'm using array.reduce() to do the job, but it is failing on Windows (testing on Mac works fine).

The file I have is formatted like this:

ford.car.focus.transmission=standard
ford.car.focus.engine=four-cylinder
ford.car.focus.fuel=gas

ford.car.taurus.transmission=automatic
ford.car.taurus.engine=V-8
ford.car.taurus.fuel=diesel

purchased=Ford Taurus

I would like to have the structure look like this:

{ ford:
  { car:
    { focus:
      {
        transmission: 'standard',
        engine: 'four-cylinder',
        fuel: 'gas'
      }
    }
    { taurus:
      {
        transmission: 'automatic',
        engine: 'V-8',
        fuel: 'diesel'
      }
    }
  }
  purchased: 'Ford Taurus'
}

I'm storing file lines in an array, splitting on '\n'. I'm trying to write a method that would be called in a loop, passing my global object like this:

var hash = {};
var array = fileData.toString().split("\n");
for (i in array) {
  var tmp = array[i].split("=");
  createNestedObjects(tmp[0], tmp[1], hash);
}

My current function looks like this:

function create_nested_object(path, value, obj) {
  var keys = path.split('.');
  keys.reduce(function(o, k) {
    if (k == keys[keys.length-1]) {
      return o[k] = value;
    } else if (o[k]) {
      return o[k];
    } else {
      return o[k] = {};
    }
  }, obj);
}

I would like to turn this into a for loop. I have new code that looks like this (I tried converting the array.reduce() code):

function create_nested_object(path, value, obj) {
  var keys = path.split('.');

  for (var i = 0; i < keys.length; i++) {
    if (keys[i] == keys[keys.length-1]) {
      obj[keys[i]] = value;
    } else if (obj[keys[i]] == keys[i]) {
      obj;
    } else {
      obj = obj[keys[i]] = {};
    }
  }
}

But it only returns the last items in each nest:

{
  "ford": {
    "car": {
      "taurus": {
        "fuel": "diesel"
      }
    }
  },
  "purchased": "Ford Taurus"
}

I know I'm missing something, but I can't figure out what's wrong. Any help would be appreciated!

Solution

EDIT to use os.EOL

solution in the comments: In the OP code:

var array = fileData.toString().split("\n");

And, as @Marty suggested, Needs to be:

var array = fileData.toString().split(os.EOL);

In Windows.
