Yii 2 Composer Installer
========================

This is the composer installer for [Yii framework 2.0](http://www.yiiframework.com) extensions.
It implements a new composer package type named `yii2-extension`,
which should be used by all Yii 2 extensions if they are distributed as composer packages.

Usage
-----

To use Yii 2 composer installer, simply set `type` to be `yii2-extension` in your `composer.json`,
like the following:

```json
{
    "type": "yii2-extension",
    "require": {
        "yiisoft/yii2": "*"
    },
    ...
}
```

You may specify a bootstrapping class in the `extra` section. The `init()` method of the class will be executed each time
the Yii 2 application is responding to a request. For example,

```json
{
    "type": "yii2-extension",
    ...,
    "extra": {
        "bootstrap": "yii\\jui\\Extension"
    }
}
```

The `Installer` class also implements a static method `setPermission()` that can be called after
a Yii 2 projected is installed, through the `post-create-project-cmd` composer script.
The method will set specified directories or files to be writable or executable, depending on
the corresponding parameters set in the `extra` section of the `composer.json` file.
For example,

```json
{
    "name": "yiisoft/yii2-app-basic",
    "type": "project",
    ...
    "scripts": {
        "post-create-project-cmd": [
            "yii\\composer\\Installer::setPermission"
        ]
    },
    "extra": {
        "writable": [
            "runtime",
            "web/assets"
        ],
        "executable": [
            "yii"
        ]
    }
}
```
