README
A package that creates PHP classes using PHP. That's it.
Installation
Install Classidy
through Composer:
$ composer require rougin/classidy
Basic Usage
Creating a simple class
Creating a PHP class only requires the Classidy
and Generator
classes:
// index.php use Rougin\Classidy\Classidy; use Rougin\Classidy\Generator; use Rougin\Classidy\Method; // ... // Create a new class definition --- $class = new Classidy; // --------------------------------- // Define the details of the class ------------ $class->setComment('Sample class for Acme.'); $class->setNamespace('Acme'); $class->setPackage('Acme'); $class->setAuthor('John Doe', 'jdoe@acme.com'); $class->setName('Greet'); // -------------------------------------------- // Add a "greet" method in the class --- $method = new Method('greet'); $method->setCodeEval(function () { return 'Hello world!'; }); $class->addMethod($method); // ------------------------------------- // Generate the class -------- $generator = new Generator; echo $generator->make($class); // ---------------------------
$ php index.php <?php namespace Acme; /** * Sample class for Acme. * * @package Acme * * @author John Doe <jdoe@acme.com> */ class Greet { public function greet() { return 'Hello world!'; } }
The setCodeLine
method can also be used for specifying code of a method in a line based format. This may be useful in adding conditions in generating code of a method:
// index.php // ... $shout = false; $method->setCodeLine(function ($lines) use ($shout) { if ($shout) { $lines[] = "return 'HELLO WORLD!';"; } else { $lines[] = "return 'Hello world!';"; } return $lines; }); // ...
Adding parent class, interfaces
The class can be added with a parent class using extendsTo
:
// index.php use Acme\Hello\Greeter; // ... // Define the details of the class --- // ... $class->extendsTo(Greeter::class); // ... // ----------------------------------- // ...
$ php index.php <?php namespace Acme; use Acme\Hello\Greeter; /** * Sample class for Acme. * * @package Acme * * @author John Doe <jdoe@acme.com> */ class Greet extends Greeter { public function greet() { return 'Hello world!'; } }
Note
If the added parent class or interface is not from the same namespace of the class to be generated, Classidy
will automatically import the said parent class/interface.
For adding interfaces, the addInterface
method can be used:
// index.php use Acme\Greetable; use Acme\Helloable; // ... // Define the details of the class ---- // ... $class->addInterface(Greetable::class); $class->addInterface(Helloable::class); // ... // ------------------------------------ // ...
$ php index.php <?php namespace Acme; use Acme\Hello\Greeter; /** * Sample class for Acme. * * @package Acme * * @author John Doe <jdoe@acme.com> */ class Greet extends Greeter implements Greetable, Helloable { public function greet() { return 'Hello world!'; } }
Adding traits
Similar in defining class and interfaces, adding a trait is possible using addTrait
:
// index.php use Acme\Hello\Traitable; // ... // Define the details of the class --- // ... $class->addTrait(Traitable::class); // ... // ----------------------------------- // ...
$ php index.php <?php namespace Acme; use Acme\Hello\Traitable; /** * Sample class for Acme. * * @package Acme * * @author John Doe <jdoe@acme.com> */ class Greet { use Traitable; public function greet() { return 'Hello world!'; } }
Adding methods
Based from the first example, the addMethod
can be used to add a method to the class:
// index.php // ... // Add a "greet" method in the class --- $method = new Method('greet'); $method->setCodeEval(function () { return 'Hello world!'; }); $class->addMethod($method); // ------------------------------------- // ...
To add arguments in a specified method, kindy use the following methods below:
// index.php // ... $method = new Method('greet'); $method->addBooleanArgument('shout') ->withDefaultValue(false); $method->setReturn('string'); $method->setCodeEval(function () { return 'Hello world!'; }); $class->addMethod($method); // ...
$ php index.php <?php namespace Acme; use Acme\Hello\Greeter; /** * Sample class for Acme. * * @package Acme * * @author John Doe <jdoe@acme.com> */ class Greet extends Greeter implements Greetable, Helloable { /** * @param boolean $shout * * @return string */ public function greet($shout = false) { return 'Hello world!'; } }
To add a class argument without being its type declared, add withoutTypeDeclared
after addClassArgument
:
// index.php // ... $method = new Method('greet'); $method->addClassArgument('test', 'Acme\Test') ->withoutTypeDeclared(); $method->setReturn('string'); $method->setCodeEval(function ($test) { return $test->hello(); }); $class->addMethod($method); // ...
$ php index.php <?php namespace Acme; use Acme\Hello\Greeter; /** * Sample class for Acme. * * @package Acme * * @author John Doe <jdoe@acme.com> */ class Greet extends Greeter implements Greetable, Helloable { /** * @param \Acme\Test $test * * @return string */ public function greet($test) { return $test->hello(); } }
A method can also be defined as protected
or private
:
// index.php // ... $method = new Method('greet'); // Set the method as "protected" --- $method->asProtected(); // --------------------------------- // Set the method as "private" --- $method->asPrivate(); // ------------------------------- // ...
Note
By default, all of the specified methods are in public
visibility.
The method can be alternatively be specified as a @method
tag in the class:
// index.php // ... $method = new Method('greet'); // ... // Set as "@method" in the class --- $method->asTag(); // --------------------------------- // ...
$ php index.php <?php namespace Acme; use Acme\Hello\Greeter; /** * Sample class for Acme. * * @method string greet(boolean $shout = false) * * @package Acme * * @author John Doe <jdoe@acme.com> */ class Greet extends Greeter implements Greetable, Helloable { }
Adding properties
Similiar to adding arguments in a method, adding properties to a class can be done by the following:
// index.php // ... $class->addStringProperty('text') ->withDefaultValue('Hello world!'); // ... // Modify "greet" method to access "text" property --- $method->setCodeEval(function () { return $this->text; }); // --------------------------------------------------- // ...
$ php index.php <?php namespace Acme; use Acme\Hello\Greeter; /** * Sample class for Acme. * * @package Acme * * @author John Doe <jdoe@acme.com> */ class Greet extends Greeter implements Greetable, Helloable { /** * @var string */ protected $text = 'Hello world!'; /** * @param boolean $shout * * @return string */ public function greet($shout = false) { return $this->text; } }
To change a visibility of a property, the methods asPublic
and asPrivate
can be used:
// index.php // ... $class->addStringProperty('text') ->asPrivate() ->withDefaultValue('Hello world!'); // ...
Note
By default, all of the specified properties are in protected
visibility.
Alternatively, the property be specified as a @property
tag in the class:
// index.php // ... $class->addStringProperty('text')->asTag(); // ...
$ php index.php <?php namespace Acme; use Acme\Hello\Greeter; /** * @property string $text * * Sample class for Acme. * * @package Acme * * @author John Doe <jdoe@acme.com> */ class Greet extends Greeter implements Greetable, Helloable { }
Setting an empty class
The setEmpty
method can be used to clear any methods and properties previously specified. This maybe useful when generating empty classes without specifying a new Classidy
class:
// index.php // ... $class->setEmpty(); // ...
$ php index.php <?php namespace Acme; use Acme\Hello\Greeter; /** * Sample class for Acme. * * @package Acme * * @author John Doe <jdoe@acme.com> */ class Greet extends Greeter implements Greetable, Helloable { }
