+/**
+ * This command manage fixtures creations based on given template.
+ *
+ * Fixtures are one of the important paths in unit testing. To speed up developers
+ * work this fixtures can be generated automatically, based on prepared template.
+ * This command is a simple wrapper for the fixtures library [Faker](https://github.com/fzaninotto/Faker).
+ * 
+ * You should configure this command as follows (you can use any alias, not only "faker:fixture"):
+ * 
+ * ~~~
+ *	'controllerMap' => [
+ *		'faker' => [
+ *			'class' => 'yii\faker\FixtureController',
+ *		],
+ *	],
+ * ~~~
+ * 
+ * To start using this command you need to be familiar (read guide) for the Faker library and
+ * generate fixtures template files, according to the given format:
+ * 
+ * ~~~
+ * #users.php file under $templatePath
+ * 
+ * return [
+ *	[
+ *		'table_column0' => 'faker_formatter',
+ *		...
+ *		'table_columnN' => 'other_faker_formatter
+ *		'table_columnN+1' => function ($fixture, $faker, $index) {
+ *			//set needed fixture fields based on different conditions
+ *			return $fixture;
+ *		}
+ *	],
+ * ];
+ * ~~~
+ * 
+ * If you use callback as a attribute value, then it will be called as shown with three parameters:
+ * * $fixture - current fixture array. 
+ * * $faker - faker generator instance
+ * * $index - current fixture index. For example if user need to generate 3 fixtures for tbl_user, it will be 0..2
+ * After you set all needed fields in callback, you need to return $fixture array back from the callback.
+ * 
+ * After you prepared needed templates for tables you can simply generate your fixtures via command
+ * 
+ * ~~~
+ * php yii faker/generate users
+ * 
+ * #also a short version of this command (generate action is default)
+ * php yii faker users
+ * ~~~
+ * 
+ * In the code above "users" is template name, after this command run, new file named same as template
+ * will be created under the $fixturesPath folder.
+ * You can generate fixtures for all templates by specifying keyword "all_fixtures"
+ * 
+ * ~~~
+ * php yii faker/generate all_fixtures
+ * ~~~
+ * 
+ * This command will generate fixtures for all template files that are stored under $templatePath and 
+ * store fixtures under $fixturesPath with file names same as templates names.
+ * 
+ * You can specify how many fixtures per file you need by the second parameter. In the code below we generate
+ * all fixtures and in each file there will be 3 rows (fixtures).
+ * 
+ * ~~~
+ * php yii faker/generate all_fixtures 3
+ * ~~~
+ * 
+ * You can specify different options of this command:
+ * 
+ * ~~~
+ * #generate fixtures in russian languge
+ * php yii faker/generate users 5 --language='ru_RU'
+ * 
+ * #read templates from the other path
+ * php yii faker/generate all_fixtures --templatePath='@app/path/to/my/custom/templates'
+ * 
+ * #generate fixtures into other folders, but be sure that this folders exists or you will get notice about that.
+ * php yii faker/generate all_fixtures --fixturesPath='@tests/unit/fixtures/subfolder1/subfolder2/subfolder3'
+ * ~~~
+ * 
+ * You also can create your own data providers for custom tables fields, see Faker library guide for more info (https://github.com/fzaninotto/Faker);
+ * After you created custom provider, for example:
+ * 
+ * ~~~
+ * 
+ *	class Book extends \Faker\Provider\Base
+ *	{
+ *		public function title($nbWords = 5)
+ *		{
+ *			$sentence = $this->generator->sentence($nbWords);
+ *			return mb_substr($sentence, 0, mb_strlen($sentence) - 1);
+ *		}
+ *
+ *		public function ISBN()
+ *		{
+ *			return $this->generator->randomNumber(13);
+ *		}
+ *	}
+ * ~~~
+ * 
+ * you can use it by adding it to the $providers property of the current command. In your console.php config:
+ * 
+ * ~~~
+ *	'controllerMap' => [
+ *		'faker' => [
+ *			'class' => 'yii\faker\FixtureController',
+ *			'providers' => [
+ *				'app\tests\unit\faker\providers\Book',

+Faker Extension for Yii 2
+===============================
+
+This extension provides a [`Faker`](https://github.com/fzaninotto/Faker) fixture command for Yii 2.
+
+Installation
+------------
+
+The preferred way to install this extension is through [composer](http://getcomposer.org/download/).
+
+Either run
+
+```
+php composer.phar require yiisoft/yii2-faker "*"
+```
+
+or add
+
+```json
+"yiisoft/yii2-faker": "*"
+```
+
+to the require section of your composer.json.
+
+Usage
+-----
+
+To use this extension,  simply add the following code in your application configuration (console.php):
+
+```php
+'controllerMap' => [
+	'faker' => [
+		'class' => 'yii\faker\FixtureController',
+	],
+],
+```
+To start using this command you need to be familiar (read guide) for the Faker library and
+generate fixtures template files, according to the given format:
+
+```php
+#users.php file under template path (by default @tests/unit/fixtures/templates)
+return [
+	[
+		'table_column0' => 'faker_formatter',
+		...
+		'table_columnN' => 'other_faker_formatter
+		'table_columnN+1' => function ($fixture, $faker, $index) {
+			//set needed fixture fields based on different conditions
+			return $fixture;
+		}
+	],
+];
+~~~
+```
+
+If you use callback as a attribute value, then it will be called as shown with three parameters:
+
+* $fixture - current fixture array. 
+* $faker - faker generator instance
+* $index - current fixture index. For example if user need to generate 3 fixtures for tbl_user, it will be 0..2.
+
+After you set all needed fields in callback, you need to return $fixture array back from the callback.
+
+After you prepared needed templates for tables you can simply generate your fixtures via command
+
+```php
+#generate fixtures for the users table based on users fixture template
+php yii faker/generate users
+
+#also a short version of this command ("generate" action is default)
+php yii faker users
+```
+
+In the code above "users" is template name, after this command run, new file named same as template
+will be created under the fixtures path (by default ```@tests/unit/fixtures```) folder.
+You can generate fixtures for all templates by specifying keyword "all_fixtures"
+
+```php
+php yii faker/generate all_fixtures
+```
+
+This command will generate fixtures for all template files that are stored under template path and 
+store fixtures under fixtures path with file names same as templates names.
+You can specify how many fixtures per file you need by the second parameter. In the code below we generate
+all fixtures and in each file there will be 3 rows (fixtures).
+
+```php
+php yii faker/generate all_fixtures 3
+```
+You can specify different options of this command:
+
+```php
+#generate fixtures in russian language
+php yii faker/generate users 5 --language='ru_RU'
+
+#read templates from the other path
+php yii faker/generate all_fixtures --templatePath='@app/path/to/my/custom/templates'
+
+#generate fixtures into other folders, but be sure that this folders exists or you will get notice about that.
+php yii faker/generate all_fixtures --fixturesPath='@tests/unit/fixtures/subfolder1/subfolder2/subfolder3'
+```
+
+You also can create your own data providers for custom tables fields, see [Faker]((https://github.com/fzaninotto/Faker)) library guide for more info;
+After you created custom provider, for example:
+
+```php
+class Book extends \Faker\Provider\Base
+{
+	public function title($nbWords = 5)
+	{
+		$sentence = $this->generator->sentence($nbWords);
+		return mb_substr($sentence, 0, mb_strlen($sentence) - 1);
+	}
+
+	public function ISBN()
+	{
+		return $this->generator->randomNumber(13);
+	}
+
+ }
+```
+
+You can use it by adding it to the $providers property of the current command. In your console.php config:
+
+```php
+'controllerMap' => [
+	'faker:fixture' => [
+		'class' => 'yii\faker\FixtureController',
+		'providers' => [
+			'app\tests\unit\faker\providers\Book',
+		],
+	],
+]
+```
