Diff support

diff

Decide on which of the 3 outputs you prefer?

#1 is a cleaned name printed with spaces between components.
#2 is a cleaned name printed with "~" between components.
#3 is every component printed using "~" to separate these.

I like the first, but it is hard to tell if they have moved a component from one field to another, and multipart names are difficult to judge the boundaries between components.

regarding the name

No, I'm not changing the technical name, just the project page title (I probably have to update the .info file at some stage to)

I decided on very generic name "Name" as CCK => Fields was in full swing, but Field does seem to have caught on. From Rays suggestion, moved to Name Field, but the code name, or module prefix or Drupal URL, etc, is staying as name.

The code for number 3 is:

<,code>

/**
 * Implementation of CCK's hook_content_diff_values().
 */
function name_content_diff_values($node, $field, $items) {
  $return = array();
  foreach ($items as $delta => $item) {
    $return[] = implode('~', $item);
  }
  return $return;
}

Committed #3. Needs porting to Drupal 7 version.

The current Diff implementation is nasty. Will try and get a push for the Diff 7 api to be modified before returning to this...

I've pushed through a version that supports the new Diff 7.x-3.x branch.

Retroactively tagging.
