@vertana/context-memory

Translation memory context sources for Vertana.

Features

This package provides a pluggable translation memory store interface, an in-memory reference implementation, and a passive context source for looking up prior translations during translation.

• TranslationMemoryStore: A storage interface for adding and searching translation memory entries.
• InMemoryTranslationMemoryStore: A deterministic in-memory backend for tests, examples, and small local memories.
• lookupMemory: A passive context source factory that exposes translation memory lookup as a tool.
