Vodka is a joke "drunk" application behavior that intercepts the response at a given probability (default is 0.75) and replaces it with some "quote" from the default or custom generators. Works for both web and console application.

Installation ¶

The preferred way to install this extension is through composer.

Either run

$ composer require tebazil/yii2-vodka-behavior

or add

"tebazil/yii2-vodka-behavior": "*"

to the require section of your composer.json file.

Basic usage ¶

VodkaBehavior is a typical yii2 behavior, that can be attached to the application. The most simple way is to attach the behavior in application's config section:

return [
    'id' => 'basic-console',
    'basePath' => dirname(__DIR__),
    'bootstrap' => ['log', 'gii'],
    ...
	'as vodka'=> [
		'class'=>'tebazil\yii2\behaviors\vodka\VodkaBehavior',
	],
	...
	'components'=>[
	...
	],
	...

There. Now when you call your application (even with non existent routes), "quotes" will appear in browser/console at a given probability.

Advanced usage ¶

You may also benefit from some additional configuration. You can configure generators, probability, and phrase to further customize a drunk behavior.
phrase (string) - is a prefix phrase to generator's output. The default value is VODKA BEHAVIOR says:
probability (float) - is a probability from 0 to 1 at which the output will be intercepted. 0 means behavior never fires. 1 means it fires all the time. The default value is 0.75. generators is the array of anonymous functions that generate the output. When you define this parameter, the default generators are replaced with the ones you specified. The anonymous function takes no parameters and returns output. For universal usage, make sure you return string from a generator. The default value of generators is array of two bundled generators.

Here is the example of full configuration:

return [
    'id' => 'basic-console',
    'basePath' => dirname(__DIR__),
    'bootstrap' => ['log', 'gii'],
    ...
	'as vodka'=> [
		'class'=>'tebazil\yii2\behaviors\vodka\VodkaBehavior',
		'probability'=>0.95,
		'phrase'=>'Hi, I am your application ... Intrigued, huh? Here is what I have to say:',
		'generators'=>[
		function() {
		  return 'I think everything is possible. You just have to listen to your heart and work hard.';
		},
		function() {
		    $coreDevs = ['Quang','Cebe','Samdark','Will Smith'];
		    $tails = [
		        'The resemblance is unique.',
		        'Sometimes they drink tea together.',
		        'But only in the dark.',
		    ];
		    $randMember = function($arr) use { return $arr[array_rand($arr)]; };
		    return $randMember($coreDevs).' looks like '.$randMember($coreDevs).'. '.$randMember($tails);
		    
		}
		]
	],
	...
	'components'=>[
	...
	],
	...

How it works ¶

When Application::EVENT_BEFORE_REQUEST happens, the probability is being calculated. If, by probability, it is not time to run - nothing happens. If it is time to run:

• In case of WebApplication, the data attribute of response is set, then the response is sent.
• In case of ConsoleApplication the output is echoed, then the the application execution ends.

Advanced generator usage ¶

You can return objects and arrays in generators. In case of ConsoleApplication, they will be displayed via print_r. In case of WebApplication the result would depend on what format you are trying to output generator's result in. For example, you might be getting error with array and object without __toString() implementation in case of html format.
