New Features
------------
Isolated Diffing of certain HTML elements
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
This is the one of the largest changes from the original repository.
For more information, see the release notes for tag `0.0.6`_
List Diffing
^^^^^^^^^^^^
Similar to the Isolated Diffing feature, but specifically for HTML lists.
More information is to come on this, and there will definitely be some tweaks and configuration options added for this
feature. Currently there is no easy way to enable/disable the feature, so if you're having issues with it I suggest
using the `0.0.6`_ or earlier release.
Table Diffing
^^^^^^^^^^^^^
Similar to the Isolated Diffing and List Diffing features, but specifically for HTML tables.
More information to come on this soon.
New option to group together diffed words by not matching on whitespace-only. Option is enabled by default.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
This was a specific requirement for an application we use this library for. The original library would replace
single words at a time, but enabling this feature will group replacements instead. See example below.
Old Text::
testing some text here and there
New Text::
testing other words here and there
With $groupDiffs = false (original functionality)::
testing <del>some</del><ins>other</ins> <del>text</del><ins>words</ins> here and there
With $groupDiffs = true (new feature)::
testing <del>some text</del><ins>other words</ins> here and there
Change diffing to strike through entire words/numbers if they contain periods or commas within the word
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
This change introduced a new property ``$specialCaseChars``, which defaults to the following characters: ``.`` ``,`` ``(`` ``)`` ``'``
This feature can be "disabled" by simply setting the $specialCaseChars to an empty array i.e. ``$diff->setSpecialCaseChars(array())``
In the original library, special characters are treated as their own "words" even if they are in the middle of a word.
This causes weird things to happen when diffing numbers that have a comma or a period in the middle of the number.
For example, diffing ``10,000.50`` against ``11,100.75`` gives you:
Original Functionality::
<del class="diffmod">10</del><ins class="diffmod">11</ins>,<del class="diffmod">000</del><ins class="diffmod">100</ins>.<del class="diffmod">50</del><ins class="diffmod">75</ins>
This is very difficult to read, so the new feature allows you to add ``.`` and ``,`` to the ``$specialCaseChars`` array in order
to get output that looks like::
<del class="diffmod">10,000.50</del><ins class="diffmod">11,100.75</ins>
Note: It will *not* treat the specialCaseChars as part of the word if it is at the beginning or end of the word,
so normal periods or commas at the end of words will still be diffed like the original.
Added option to insert a space between ``<del>`` and ``<ins>`` tags. Disabled by default.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
This was a requirement for one our applications that uses this library.
New property ``$insertSpaceInReplace`` was added, and setting it to true will simply add a space between
the ``<del>`` and ``<ins>`` tags in replace operations, which was requested for easier reading.
Enable it by calling ``$diff->setInsertSpaceInReplace(true);``
Original Functionality::
<del>Old</del><ins>New</ins>
New Functionality::
<del>Old</del> <ins>New</ins>
