pass thru of arrays

[Michael Nielsen]

Hi

Thank you for a nice diff library. Our need is simply to get the new/updated array passed back as the diff. Having options to diff(.., {returnArray:true}) would be nice.

The code:
in diff/index.js justafter line 55
if (Array.isArray(r)) {
return r;
}

Regards
Michael

Hey @michaelreflective thanks for raising an issue.

I'm not quite sure I understand what you're asking for, would you mind adding a code example?

Hi Thank you for your time. Sure I will explain more what is our simple need. We simply see arrays as a value, that if different from existing will simply override the full array. And yes if there is a big structure under, it will be overriden, but that is fine. So, array is to be seen and interpreted as a scalar. If different then just return rhs. In the types we have in the datamodel, usage of arrays, are limited to list of values, so no deep structure under. If you like to have more control over the change, the existing solution gives you all the information needed. Perhaps an indication of that the left value was an array, could be handy. Code: index.js from line: 49 var diff = function diff(lhs, rhs) { if (lhs === rhs) return {}; // equal return no diff if (!(0, _utils.isObject)(lhs) || !(0, _utils.isObject)(rhs)) return rhs; // return updated rhs var l = (0, _utils.properObject)(lhs); var r = (0, _utils.properObject)(rhs); // MN: Pass arrays on right thru if it != left // perhaps have a 3. arg: options: {scalarArray: true} // I have imp. Array.protocol.equals, also. if (Array.isArray(r)) { if (l.equals(r) === false) { return r; } } // and done

Hey sorry @michaelreflective for not coming back to you sooner! I'm still not sure if I understand the issue you are having. Would you mind taking a look at #23 to see if it is the same issue and if my comments are relevant to your use case? Thanks!
