README

State-agnostic class files finder, based on Composer autoload information, without actually applying autoloader in PHP process. The scope of this package is to retrieve the file location for classes of particular Composer-based projects.

This way classes can be resolved standalone without actually loading them into memory, since class loading is not invoked at all.

Plain Composer

<?php
require_once __DIR__ . '/vendor/autoload.php';

$directory = '/other/project/vendor';
$finder = \OliverHader\ComposerClassFinder\TYPO3::resolveFinder($directory);
$filePath = $finder->findFile('Vendor\\Project\\Some\\Utility');

TYPO3 specific

resolving composer-mode of a project

This basically resolves information concerning TYPO3 "composer-mode".

$bool = \OliverHader\ComposerClassFinder\TYPO3::isComposerMode($directory);

$directory set to location of root composer.json returns true (given there actually is a valid TYPO3 composer-based installation)
$directory set to location to web-root (containing index.php and typo3conf/autoload/) returns false

applying corresponding autoload information

Same rules as in previous composer-mode section apply for $directory. The library won't do much directory traversing - exceptions are thrown when providing invalid directories. Thus, it's your job to provide correct values.

Information is fetched from either composer-based data (just vendor/) or in non-composer-mode from <typo3_src>/vendor/ and <web-root>/typo3conf/autoload/.

$finder = \OliverHader\ComposerClassFinder\TYPO3::resolveFinder($directory);
$filePath = $finder->findFile('BK2K\\BootstrapPackage\\Backend\\ToolbarItem\\VersionToolbarItem');

Thanks to Composer Folks

Basically this package is just a wrapper for existing Composer class-loader, the corresponding code has been duplicated from https://github.com/composer/composer.

Thanks a bunch for your great work! 👍
