FineDiff
========

[](#finediff)

Originally written by Raymond Hill () FineDiff has been tweaked to bring it up to date with the modern world. That means documented, nicely formatted, tested code that can be easily extended.

[![Build Status](https://camo.githubusercontent.com/c8e78a0cc9fb8cb5b4bc6a4482c47726356412ad16cdca823bd842bd429d51d7/68747470733a2f2f7472617669732d63692e6f72672f6261726965772f46696e65446966662e706e673f6272616e63683d6d6173746572)](https://travis-ci.org/bariew/FineDiff)

Installation
------------

[](#installation)

**Composer**

The preferred way of using FineDiff is through [Composer](http://getcomposer.org).

Add the following to your composer.json file:

```
{
    "require": {
        "bariew/finediff": "0.3.*"
    }
}
```

Upgrading
---------

[](#upgrading)

**0.3.x** introduces a backwards incompatible version, so if you have stored opcodes do not upgrade!

`0.3.x` fixes a double encoding issue that generates a longer opcode than is needed.

Usage
-----

[](#usage)

**Render HTML**

Render as HTML the difference between two strings:

```
$diff = new bariew\FineDiff\Diff;
echo $diff->render('string one', 'string two');
```

This would then output:

```
string twone
```

You could change the granularity to `bariew\FineDiff\Granularity\Word` so the output is:

```
string onetwo
```

You do this by passing it into the Diff constructor:

```
$granularity = new bariew\FineDiff\Granularity\Word;
$diff        = new bariew\FineDiff\Diff($granularity);
```

**Grab opcode instructions**

Opcode instructions are what tell FineDiff how to change one string into another.

```
$diff = new bariew\FineDiff\Diff;
echo $diff->getOpcodes('string one', 'string two');
```

This would then output:

```
c7d3i3:two
```

Render text using the opcodes:

```
$render = new bariew\FineDiff\Render\Text;
echo $render->process('string one', 'c7d3i3:two');
```

Would output:

```
string two
```

Same with HTML:

```
$render = new bariew\FineDiff\Render\Html;
echo $render->process('string one', 'c7d3i3:two');
```
