README

Yii Aliases

The package aim is to store path aliases, i.e. short name representing a long path (a file path, a URL, etc.). Path alias value may have another value as its part. For example, @vendor may store path to vendor directory while @bin may store @vendor/bin.

Requirements

• PHP 7.4 or higher.

Installation

The package could be installed with composer:

composer require yiisoft/aliases --prefer-dist

General usage

A path alias must start with the character '@' so that it can be easily differentiated from non-alias paths.

use Yiisoft\Aliases\Aliases;

$aliases = new Aliases([
    '@root' => __DIR__,
]);
$aliases->set('@vendor', '@root/vendor');
$aliases->set('@bin', '@vendor/bin');

echo $aliases->get('@bin/phpunit');

The code about would output "/path/to/vendor/bin/phpunit".

Note that set() method does not check if the given path exists or not. All it does is to associate the alias with the path.

The path could be:

• a directory or a file path (e.g. /tmp, /tmp/main.txt)
• a URL (e.g. http://www.yiiframework.com)
• a path alias (e.g. @yii/base). It will be resolved on {@see get()} call.

Any trailing / and \ characters in the given path will be trimmed.

To bulk translate path aliases into actual paths use getArray() method:

$aliases = new Aliases([
    '@root' => '/my/app',
]);

// Value will be ['src' => '/my/app/src', 'tests' => '/my/app/tests']
$directories = $aliases->getAll(['src' => '@root/src', 'tests' => '@root/tests']);

Alias priorities

In case multiple aliases are registered with same root (prefix), then the most specific has precedence:

use Yiisoft\Aliases\Aliases;

$aliases = new Aliases([
    '@vendor' => __DIR__ . '/vendor',
    '@vendor/test' => '/special/location'    
]);
echo $aliases->get('@vendor/test');

That would output /special/location since @vendor/test is more specific match than @vendor.

Alias removal

If you need to remove alias runtime:

use Yiisoft\Aliases\Aliases;

$aliases = new Aliases([
    '@root' => __DIR__,
]);
$aliases->remove('@root');
