Create and access git repositories
==================================

gitlib provides methods to initialize new repositories.

Create a repository
-------------------

To initialize a new repository, use method `Admin::init`.

```php
// Initialize a bare repository
$repository = Gitonomy\Git\Admin::init('/path/to/repository');

// Initialize a non-bare repository
$repository = Gitonomy\Git\Admin::init('/path/to/repository', false);
```

Default behavior is to create a bare repository. If you want to
initialize a repository with a working copy,pass `false` as third
argument of Repository constructor.

Cloning repositories
--------------------

You can clone a repository from an URL by doing:

```php
// Clone to a bare repository
$repository = Gitonomy\Git\Admin::cloneTo('/tmp/gitlib', 'https://github.com/gitonomy/gitlib.git');

// Clone to a non-bare repository
$repository = Gitonomy\Git\Admin::cloneTo('/tmp/gitlib', 'https://github.com/gitonomy/gitlib.git', false);
```

Default behavior is to clone in a bare repository.

You can also clone a repository and point it to a specific branch. In a
non-bare repository, this branch will be checked out:

```php
// Clone to a bare repository
$repository = Gitonomy\Git\Admin::cloneBranchTo('/tmp/gitlib', 'https://github.com/gitonomy/gitlib.git', 'a-branch');

// Clone to a non-bare repository
$repository = Gitonomy\Git\Admin::cloneBranchTo('/tmp/gitlib', 'https://github.com/gitonomy/gitlib.git', 'a-branch', false);
```

Clone a Repository object
-------------------------

If you already have a Repository instance and want to clone it, you can
use this shortcut:

```php
$new = $repository->cloneTo('/tmp/clone');
```

Mirror a repository
-------------------

If you want to mirror fully a repository and all references, use the
`mirrorTo` method. This method takes only two arguments, where to mirror
and what to mirror:

```php
// Mirror to a bare repository
$mirror = Gitonomy\Git\Admin::mirrorTo('/tmp/mirror', 'https://github.com/gitonomy/gitlib.git');

// Mirror to a non-bare repository
$mirror = Gitonomy\Git\Admin::mirrorTo('/tmp/mirror', 'https://github.com/gitonomy/gitlib.git', false);
```
