See the included demo for reference or view a sample on Codepen.

<pre line-diff left-obj="left" right-obj="right"></pre>

Where left and right are defined on your scope. The options attribute can be used as well, but it’s optional.

$scope.options = {
  editCost: 4,
  attrs: {
    insert: {
      'data-attr': 'insert',
      'class': 'insertion'
    delete: {
      'data-attr': 'delete'
    equal: {
      'data-attr': 'equal'

editCost is specific to processingDiff and controls the tolerence for hunk separation. attrs can contain any/all/none of the following: insert, delete, and equal where the properties in those objects represent attributes that get added to the tags.

Add some style

  color: gray;
