Installing

composer require phil/translation-memory

It is a library, not a bundle: there is nothing to register. Its services hold no state between two calls — build them once and keep them:

use Phil\TranslationMemory\Memory\InMemoryStore;
use Phil\TranslationMemory\Memory\TranslationMemory;
use Phil\TranslationMemory\Segmentation\Granularity;
use Phil\TranslationMemory\Segmentation\UjoSegmenter;

$segmenter = new UjoSegmenter(Granularity::Block);
$memory = new TranslationMemory(new InMemoryStore(), minimum: 0.7, limit: 5);

The memory needs a store: InMemoryStore for tests and small memories loaded from a file, or an implementation of MemoryStore over the application's database. In a Symfony application, phil/translation-bundle provides a Doctrine store, keeps the segments and wires everything as services.
