Table of Contents (ToC) ----------------------- [](#table-of-contents-toc) - [Introduction](#introduction) - [Features](#features) - [Requirements](#requirements) - [Usage](#usage) - [Installation](#installation) - [Testing](#testing) - [Contributing](#contributing) - [Credits](#credits) - [License](#license) Introduction ------------ [](#introduction) This component is inspired by the method [`java.lang.Object.toString`](http://docs.oracle.com/javase/7/docs/api/java/lang/Object.html#toString() "Object (Java Platform SE 7)") of the [Java](http://java.com "Java") programming language. **Component\\Core\\DebugPrint** consists of two artifacts: 1. The interface [`FlorianWolters\Component\Core\DebugPrintInterface`](src/main/php/DebugPrintInterface.php "FlorianWolters\Component\Core\DebugPrintInterface"): Indicates that an implementing class provides a *Debug Print Method* for objects. 2. The trait [`FlorianWolters\Component\Core\DebugPrintTrait`](src/main/php/DebugPrintTrait.php "FlorianWolters\Component\Core\DebugPrintTrait"): Provides a default *Debug Print Method* implementation for objects. Features -------- [](#features) - Offers a default hash code value implementation for objects via the method `toString` of the trait [`FlorianWolters\Component\Core\DebugPrintTrait`](src/main/php/DebugPrintTrait.php "FlorianWolters\Component\Core\DebugPrintTrait"). Refer to the section [Usage](#using-the-default-implementation) below for an example. - Allows to create a custom hash code value implementation by implementing the interface [`FlorianWolters\Component\Core\DebugPrintInterface`](src/main/php/DebugPrintInterface.php "FlorianWolters\Component\Core\DebugPrintInterface"), more precisely implementing the public method `toString` of that interface. Refer to the section [Usage](#using-a-custom-implementation) below for an example. - Artifacts tested with both static and dynamic test procedures: - Dynamic component tests (unit and integration tests) implemented with [PHPUnit](https://phpunit.de "PHPUnit"). - Static code analysis performed using the following tools: - [PHP\_CodeSniffer](https://pear.php.net/package/PHP_CodeSniffer "PHP_CodeSniffer"): Style Checker - [PHP Mess Detector (PHPMD)](http://phpmd.org "PHPMD - PHP Mess Detector"): Code Analyzer - [PHP Depend](http://pdepend.org "PHP Depend - Software Metrics for PHP"): Code Metrics - [phpcpd](https://github.com/sebastianbergmann/phpcpd "sebastianbergmann/phpcpd · GitHub"): Copy/Paste Detector (CPD) - [phpdcd](https://github.com/sebastianbergmann/phpdcd "sebastianbergmann/phpdcd · GitHub"): Dead Code Detector (DCD) - [SensioLabs Security Checker](https://github.com/sensiolabs/security-checker "SensioLabs Security Checker"): Security Checker - Continuous Integration (CI) using the following web services: - [Scrutinizer CI](https://scrutinizer-ci.com "Scrutinizer CI") - [SensioLabsInsight](https://insight.sensiolabs.com "SensioLabsInsight") - [Coveralls](https://coveralls.io "Coveralls") - [VersionEye](https://versioneye.com "VersionEye") - [Depending](https://depending.in "Depending") - [Waffle](https://waffle.io "Waffle") - Provides a [Packagist](https://packagist.org "Packagist") package which can be installed using the dependency manager [Composer](https://getcomposer.org "Composer"). Click [here](https://packagist.org/packages/florianwolters/component-core-debugprint "florianwolters/component-core-debugprint - Packagist") for the package on [Packagist](https://packagist.org "Packagist"). - Provides a complete Application Programming Interface (API) documentation generated with the documentation generator [Sami](https://github.com/fabpot/sami "fabpot/sami · GitHub"). Click [here](http://blog.florianwolters.de/PHP-Component-Core-DebugPrint "Application Programming Interface (API) documentation") for the API documentation. - Follows the following "standards" from the [PHP Framework Interoperability Group (FIG)](http://php-fig.org "PHP-FIG — PHP Framework Interop Group"). PSR stands for PHP Standards Recommendation: - [PSR-0](http://php-fig.org/psr/psr-0 "PSR-0 requirements for autoloader interoperability"): Autoloading Standards > Aims to provide a standard file, class and namespace convention to allow plug-and-play code. - [PSR-1](http://php-fig.org/psr/psr-1 "PSR-1 basic coding style guide"): Basic Coding Standard > Aims to ensure a high level of technical interoperability between shared PHP code. - [PSR-2](http://php-fig.org/psr/psr-2 "PSR-2 coding style guide"): Coding Style Guide > Provides a Coding Style Guide for projects looking to standardize their code. - [PSR-4](http://php-fig.org/psr/psr-4 "PSR-4: Improved Autoloading"): Autoloader > A more modern take on autoloading reflecting advances in the ecosystem. - Follows the [Semantic Versioning](http://semver.org "Semantic Versioning") (SemVer) specification version 2.0.0. Requirements ------------ [](#requirements) ### Production [](#production) - [PHP](https://php.net "PHP: Hypertext Preprocessor") >= 5.4 - [Composer](https://getcomposer.org "Composer") ### Development [](#development) - [PHPUnit](https://phpunit.de "PHPUnit") - [phpcpd](https://github.com/sebastianbergmann/phpcpd "sebastianbergmann/phpcpd · GitHub") - [phpdcd](https://github.com/sebastianbergmann/phpdcd "sebastianbergmann/phpdcd · GitHub") - [PHP\_CodeSniffer](https://pear.php.net/package/PHP_CodeSniffer "PHP_CodeSniffer") - [PHP Mess Detector (PHPMD)](http://phpmd.org "PHPMD - PHP Mess Detector") - [Sami](https://github.com/fabpot/sami "fabpot/sami · GitHub") - [SensioLabs Security Checker](https://github.com/sensiolabs/security-checker "SensioLabs Security Checker") - [php-coveralls](https://github.com/satooshi/php-coveralls "satooshi/php-coveralls · GitHub") Installation ------------ [](#installation) **Component\\Core\\DebugPrint** should be installed using the dependency manager [Composer](https://getcomposer.org "Composer"). > [Composer](https://getcomposer.org "Composer") is a tool for dependency management in [PHP](https://php.net "PHP: Hypertext Preprocessor"). It allows you to declare the dependent libraries your project needs and it will install them in your project for you. The [Composer](https://getcomposer.org "Composer") installer can be downloaded with `php`. ``` php -r "readfile('https://getcomposer.org/installer');" | php ``` > This will just check a few [PHP](https://php.net "PHP: Hypertext Preprocessor") settings and then download `composer.phar`to your working directory. This file is the [Composer](https://getcomposer.org "Composer") binary. It is a PHAR ([PHP](https://php.net "PHP: Hypertext Preprocessor") archive), which is an archive format for [PHP](https://php.net "PHP: Hypertext Preprocessor") which can be run on the command line, amongst other things. > To resolve and download dependencies, run the `install` command: ``` php composer.phar install ``` If you are creating a component that relies on **Component\\Core\\DebugPrint**, please make sure that you add **Component\\Core\\DebugPrint** to your component's `composer.json` file: ``` { "require": { "florianwolters/component-core-debugprint": "0.3.*" } } ``` Usage ----- [](#usage) The best documentation for **\\Component\\Core\\DebugPrint** are the unit tests, which are shipped in the package. The most important usage rule: > Always implement the interface [`DebugPrintInterface`](src/main/php/DebugPrintInterface.php "FlorianWolters\Component\Core\DebugPrintInterface") if using the trait [`DebugPrintTrait`](src/main/php/DebugPrintTrait.php "FlorianWolters\Component\Core\DebugPrintTrait"), since that allows [Type Hinting](https://php.net/language.oop5.typehinting "PHP: Type Hinting - Manual"). The class [`DebugPrintExample`](resources/php/DebugPrintExample.php "FlorianWolters\Example\DebugPrintExample") can be run via the command `php resources/php/DebugPrintExample.php` from the root of the project. ### Default *Debug Print Method* [](#default-debug-print-method) The class [`DebugPrintDefaultImpl`](src/test/resources/DebugPrintDefaultImpl.php "FlorianWolters\Example\DebugPrintDefaultImpl.php") uses the default implementation of the trait [`DebugPrintTrait`](src/main/php/DebugPrintTrait.php "FlorianWolters\Component\Core\DebugPrintTrait"). ### Custom *Debug Print Method* [](#custom-debug-print-method) The class [`DebugPrintCustomImpl`](src/test/resources/DebugPrintCustomImpl.php "FlorianWolters\Example\DebugPrintCustomImpl.php") implements a custom implementation, which fulfills the design contract for a *Value Object*.
