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

[](#installation)

```
composer require superscanner/finediff
```

Usage
-----

[](#usage)

### Render HTML

[](#render-html)

Render the difference between two strings as HTML:

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

This would then output:

```
string twone
```

You could change the granularity to `CogPowered\FineDiff\Granularity\Word`

```
$diff = new FineDiff\Diff(new FineDiff\Granularity\Word());
// Or via the setter method:
$diff->setGranularity(new FineDiff\Granularity\Word());
```

so the output is:

```
string onetwo
```

You do this by passing it into the Diff constructor:

### Grab opcode instructions

[](#grab-opcode-instructions)

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

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

This would then output:

```
c7d3i3:two
```

Render text using the opcodes:

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

Would output:

```
string two
```

Same with HTML:

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