# Contributor Covenant Code of Conduct
## Our Pledge
In the interest of fostering an open and welcoming environment, we as
contributors and maintainers pledge to making participation in our project and
our community a harassment-free experience for everyone, regardless of age, body
size, disability, ethnicity, gender identity and expression, level of experience,
nationality, personal appearance, race, religion, or sexual identity and
orientation.
## Our Standards
Examples of behavior that contributes to creating a positive environment
include:
* Using welcoming and inclusive language
* Being respectful of differing viewpoints and experiences
* Gracefully accepting constructive criticism
* Focusing on what is best for the community
* Showing empathy towards other community members
Examples of unacceptable behavior by participants include:
* The use of sexualized language or imagery and unwelcome sexual attention or
advances
* Trolling, insulting/derogatory comments, and personal or political attacks
* Public or private harassment
* Publishing others' private information, such as a physical or electronic
address, without explicit permission
* Other conduct which could reasonably be considered inappropriate in a
professional setting
## Our Responsibilities
Project maintainers are responsible for clarifying the standards of acceptable
behavior and are expected to take appropriate and fair corrective action in
response to any instances of unacceptable behavior.
Project maintainers have the right and responsibility to remove, edit, or
reject comments, commits, code, wiki edits, issues, and other contributions
that are not aligned to this Code of Conduct, or to ban temporarily or
permanently any contributor for other behaviors that they deem inappropriate,
threatening, offensive, or harmful.
## Scope
This Code of Conduct applies both within project spaces and in public spaces
when an individual is representing the project or its community. Examples of
representing a project or community include using an official project e-mail
address, posting via an official social media account, or acting as an appointed
representative at an online or offline event. Representation of a project may be
further defined and clarified by project maintainers.
## Enforcement
Instances of abusive, harassing, or otherwise unacceptable behavior may be
reported by contacting the project team at dev@caxy.com. All
complaints will be reviewed and investigated and will result in a response that
is deemed necessary and appropriate to the circumstances. The project team is
obligated to maintain confidentiality with regard to the reporter of an incident.
Further details of specific enforcement policies may be posted separately.
Project maintainers who do not follow or enforce the Code of Conduct in good
faith may face temporary or permanent repercussions as determined by other
members of the project's leadership.
## Attribution
This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
available at [http://contributor-covenant.org/version/1/4][version]
[homepage]: http://contributor-covenant.org
[version]: http://contributor-covenant.org/version/1/4/

Contributing
============
First of all, **thank you** for contributing, **you are awesome**!
Here are a few rules to follow in order to ease code reviews, and discussions before
maintainers accept and merge your work.
You MUST follow the [PSR-1](http://www.php-fig.org/psr/1/) and
[PSR-2](http://www.php-fig.org/psr/2/). If you don't know about any of them, you
should really read the recommendations. Can't wait? Use the [PHP-CS-Fixer
tool](http://cs.sensiolabs.org/).
You MUST run the test suite.
You MUST write (or update) unit tests.
You SHOULD write documentation.
Please, write [commit messages that make
sense](http://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html),
and [rebase your branch](http://git-scm.com/book/en/Git-Branching-Rebasing)
before submitting your Pull Request.
One may ask you to [squash your
commits](http://gitready.com/advanced/2009/02/10/squashing-commits-with-rebase.html)
too. This is used to "clean" your Pull Request before merging it (we don't want
commits such as `fix tests`, `fix 2`, `fix 3`, etc.).
Also, while creating your Pull Request on GitHub, you MUST write a description
which gives the context and/or explains why you are creating it.
Thank you!

For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights.
We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations.
Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and modification follow.
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program.
You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License.
c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program.
In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License.
3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable.
If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance.
5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License.
7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice.
This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation.
10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found.
one line to give the program's name and an idea of what it does.
Copyright (C) yyyy name of author
This program is free software; you can redistribute it and/or
modify it under the terms of the GNU General Public License
as published by the Free Software Foundation; either version 2
of the License, or (at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA.
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details
type `show w'. This is free software, and you are welcome
to redistribute it under certain conditions; type `show c'
for details.
The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright
interest in the program `Gnomovision'
(which makes passes at compilers) written
by James Hacker.
signature of Ty Coon, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Lesser General Public License instead of this License.

php-htmldiff is a library for comparing two HTML files/snippets and highlighting the differences using simple HTML.
This HTML Diff implementation was forked from [rashid2538/php-htmldiff][upstream] and has been modified with new features,
bug fixes, and enhancements to the original code.
For more information on these modifications, read the [differences from rashid2538/php-htmldiff][differences] or view the [CHANGELOG][changelog].
## Installation
The recommended way to install php-htmldiff is through [Composer][composer].
Require the [caxy/php-htmldiff][badge_packagist] package by running following command:
```sh
composer require caxy/php-htmldiff
```
This will resolve the latest stable version.
Otherwise, install the library and setup the autoloader yourself.
### Working with Symfony
If you are using Symfony, you can use the [caxy/HtmlDiffBundle][htmldiffbundle] to make life easy!
## Usage
```php
use Caxy\HtmlDiff\HtmlDiff;
$htmlDiff = new HtmlDiff($oldHtml, $newHtml);
$content = $htmlDiff->build();
```
## Configuration
The configuration for HtmlDiff is contained in the `Caxy\HtmlDiff\HtmlDiffConfig` class.
There are two ways to set the configuration:
1. [Configure an Existing HtmlDiff Object](#configure-an-existing-htmldiff-object)
2. [Create and Use a HtmlDiffConfig Object](#create-and-use-a-htmldiffconfig-object)
#### Configure an Existing HtmlDiff Object
When a new `HtmlDiff` object is created, it creates a `HtmlDiffConfig` object with the default configuration.
You can change the configuration using setters on the object:
```php
use Caxy\HtmlDiff\HtmlDiff;
// ...
$htmlDiff = new HtmlDiff($oldHtml, $newHtml);
// Set some of the configuration options.
$htmlDiff->getConfig()
->setMatchThreshold(80)
->setInsertSpaceInReplace(true)
;
// Calculate the differences using the configuration and get the html diff.
$content = $htmlDiff->build();
// ...
```
#### Create and Use a HtmlDiffConfig Object
You can also set the configuration by creating an instance of
`Caxy\HtmlDiff\HtmlDiffConfig` and using it when creating a new `HtmlDiff`
object using `HtmlDiff::create`.
This is useful when creating more than one instance of `HtmlDiff`:
```php
use Caxy\HtmlDiff\HtmlDiff;
use Caxy\HtmlDiff\HtmlDiffConfig;
// ...
$config = new HtmlDiffConfig();
$config
->setMatchThreshold(95)
->setInsertSpaceInReplace(true)
;
// Create an HtmlDiff object with the custom configuration.
$firstHtmlDiff = HtmlDiff::create($oldHtml, $newHtml, $config);
$firstContent = $firstHtmlDiff->build();
$secondHtmlDiff = HtmlDiff::create($oldHtml2, $newHtml2, $config);
$secondHtmlDiff->getConfig()->setMatchThreshold(50);
$secondContent = $secondHtmlDiff->build();
// ...
```
#### Full Configuration with Defaults:
```php
$config = new HtmlDiffConfig();
$config
// Percentage required for list items to be considered a match.
->setMatchThreshold(80)
// Set the encoding of the text to be diffed.
->setEncoding('UTF-8')
// If true, a space will be added between the <del> and <ins> tags of text that was replaced.
->setInsertSpaceInReplace(false)
// Option to disable the new Table Diffing feature and treat tables as regular text.
->setUseTableDiffing(true)
// Pass an instance of \Doctrine\Common\Cache\Cache to cache the calculated diffs.
->setCacheProvider(null)
// Set the cache directory that HTMLPurifier should use.
->setPurifierCacheLocation(null)
// Group consecutive deletions and insertions instead of showing a deletion and insertion for each word individually.
->setGroupDiffs(true)
// List of characters to consider part of a single word when in the middle of text.
->setSpecialCaseChars(array('.', ',', '(', ')', '\''))
// List of tags to treat as special case tags.
->setSpecialCaseTags(array('strong', 'b', 'i', 'big', 'small', 'u', 'sub', 'sup', 'strike', 's', 'p'))
// List of tags (and their replacement strings) to be diffed in isolation.
->setIsolatedDiffTags(array(
'ol' => '[[REPLACE_ORDERED_LIST]]',
'ul' => '[[REPLACE_UNORDERED_LIST]]',
'sub' => '[[REPLACE_SUB_SCRIPT]]',
'sup' => '[[REPLACE_SUPER_SCRIPT]]',
'dl' => '[[REPLACE_DEFINITION_LIST]]',
'table' => '[[REPLACE_TABLE]]',
'strong' => '[[REPLACE_STRONG]]',
'b' => '[[REPLACE_B]]',
'em' => '[[REPLACE_EM]]',
'i' => '[[REPLACE_I]]',
'a' => '[[REPLACE_A]]',
))
;
```

Differences from rashid2538/php-htmldiff
========================================
.. contents:: Table of Contents
Code Styling and Clean-up
-------------------------
* Added namespaces, split up classes to their own files, some code styling changes
Enhancements
------------
* Allow the specialCaseOpeningTags and specialCaseClosingTags properties to be modified by passing an array into the constructor or using set/add/remove functions
* Updated the demo to accept input and diff via AJAX
* Added static properties for the default config variables
Bug Fixes
---------
* Fixed an index out of range bug (may have been fixed on the original repo since): c9ba1fa_
* Check for empty oldText or newText before processing del or ins in processReplaceOperation function
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>
