Pearify — Like Browserify, For PEAR compliance

Pearify is a tool to rewrite PSR-0 and PSR-4 PHP class names to the PEAR naming conventions. Pearify is based on the excellent PHP class-rewriting project by Michael Tibben.

Requirements

Pearify requires PHP version 5.4 or greater.

Installation

The simplest way to get Pearify is via Packagist. Simply add mridang/pearify to your composer JSON's list of requirements and run composer install.

About

Pearify relies heavily on Composer and works only on Composer-based projects. Pearify uses the classmap generated by Composer to get a list of PHP classes to be renamed.

Pearify requires that you have dumped the optimised autoload classmap so it can include the array of file paths. You can generate the classmap by invoking

composer dump-autoload --optimize

Running the aforementioned command, will generate a file called autoload_classmap.php in the vendor\composer directory. More information on the dump-autoload directive can be found at https://getcomposer.org/doc/03-cli.md#dump-autoload.

The classmap contains an exhaustive list of all the PHP classnames (including paths of dev dependencies) and the relative file paths. While this file contains classes from development dependencies as well, they are automatically excluded by Pearify.

Pearify reads your project's composer.json file to recursively deduce all the production dependencies of your project and only select classes from the classmap belonging to your project's production dependencies.

If you had a PHP class file called MyClass.php in the directory vendor/myname/myproject/

namespace MyName\MyProject;

use DateTime;

class MyClass {

    public function getDate() {
        return new DateTime("2014-10-20");
    }
}

It would be renamed and copied over to a file name lib\MyName\MyProject\MyClass.php

class MyName_MyProject_MyClass {

    public function getDate() {
        return new DateTime("2014-10-20");
    }
}

The original file is left untouched and the new file is created (or overwritten) with all the use and namespace statements removed.

Gotchas

Pearify has quite a few shortcomings. If you'd like to see support for one of the following added to Composer, please create a pull-request.

• Only the vendor directory is processed. No support for the vendor-dir property as shown at https://getcomposer.org/doc/06-config.md#vendor-dir
• No support for the suggested dependencies using the suggests property as shown at https://getcomposer.org/doc/04-schema.md#suggest
• Files without any classes are excluded
• Resources in the dependencies are excluded
• Tests in the dependencies are excluded
