Blaming files
=============

Line-per-line iteration
-----------------------

To iterate on lines of a blame:

```php
$blame = $repository->getBlame('master', 'README.md');

foreach ($blame->getLines() as $lineNumber => $line) {
    $commit = $line->getCommit();
    echo $lineNumber.': '.$line->getContent().'    - '.$commit->getAuthorName().PHP_EOL;
}
```

The *getLines* method returns an array indexed starting from 1.

As you can see, you can access the commit object related to the line you
are iterating on.

If you want to access directly a line:

```php
$line = $blame->getLine(32);
```

The Line object
---------------

LineObject represents an item of the blame file. It is composed of those
informations:

```php
$line->getCommit();  // returns a Commit
$line->getContent(); // returns text

// you can access author from commmit:
$author = $line->getCommit()->getAuthorName();
```

Group reading by commit
-----------------------

If you plan to display it, you'll probably need a version where lines
from same commit are grouped.

To do so, use the *getGroupedLines* method that will return an array
like this:

```php
$blame = array(
    array(Commit, array(1 => Line, 2 => Line, 3 => Line)),
    array(Commit, array(4 => Line)),
    array(Commit, array(5 => Line, 6 => Line))
)
```
