Installation

For PHP5, use 1.3

composer require wamania/php-stemmer "^1.3"

For PHP7 use 2.x (branch 2.x is backward compatible with 1.x)

composer require wamania/php-stemmer "^2.0"

For PHP^7.3 and PHP^8.0 use 3.x (backward compatible, but phpunit^9 don't work with php < 7.3)

composer require wamania/php-stemmer "^3.0"

Usage

For 2.x, you should use the factory

use Wamania\Snowball\StemmerFactory;

// use ISO_639 (2 or 3 letters) or language name in english
$stemmer = StemmerFactory::create('fr');
$stemmer = StemmerFactory::create ('spanish');

// then 
$stem = $stemmer->stem('automóvil');

Or the manager

use Wamania\Snowball\StemmerManager;

$manager = new StemmerManager();
$stem = $manager->stem('automóvil', 'es');

In 1.3, you must instantiate manually

use Wamania\Snowball\French;

$stemmer = new French();
$stem = $stemmer->stem('anticonstitutionnellement');
