# sebastian/diff
|
|
|
|
Diff implementation for PHP, factored out of PHPUnit into a stand-alone component.
|
|
|
|
## Installation
|
|
|
|
You can add this library as a local, per-project dependency to your project using [Composer](https://getcomposer.org/):
|
|
|
|
composer require sebastian/diff
|
|
|
|
If you only need this library during development, for instance to run your project's test suite, then you should add it as a development-time dependency:
|
|
|
|
composer require --dev sebastian/diff
|
|
|
|
### Usage
|
|
|
|
The `Differ` class can be used to generate a textual representation of the difference between two strings:
|
|
|
|
```php
|
|
use SebastianBergmann\Diff\Differ;
|
|
|
|
$differ = new Differ;
|
|
print $differ->diff('foo', 'bar');
|
|
```
|
|
|
|
The code above yields the output below:
|
|
|
|
--- Original
|
|
+++ New
|
|
@@ @@
|
|
-foo
|
|
+bar
|
|
|
|
The `Parser` class can be used to parse a unified diff into an object graph:
|
|
|
|
```php
|
|
use SebastianBergmann\Diff\Parser;
|
|
use SebastianBergmann\Git;
|
|
|
|
$git = new Git('/usr/local/src/money');
|
|
|
|
$diff = $git->getDiff(
|
|
'948a1a07768d8edd10dcefa8315c1cbeffb31833',
|
|
'c07a373d2399f3e686234c4f7f088d635eb9641b'
|
|
);
|
|
|
|
$parser = new Parser;
|
|
|
|
print_r($parser->parse($diff));
|
|
```
|
|
|
|
The code above yields the output below:
