Zaya.Translator.Impl.Yandex 2.0.0

Zaya.Translator

Pluggable translation and translation-cache abstractions for the Zaya ecosystem — engines expose metadata and SettingDescriptors; hosts create translator sessions and optionally wrap them with a cache plugin.

Packages

Requires Zaya.Primitives 2.0.0. Plugin engines also use Zaya.Logging 1.0.0.

Update channels (GitHub Releases):

• Translator engines: plugin-Zaya.Translator-v2.0-latest
• Cache engine: plugin-Zaya.TranslatorCache-v2.0-latest

See versioning and CHANGELOG.

Docs: API & articles

Features

• ITranslatorService — engine id, localized name/description, Settings, CreateSessionAsync
• ITranslatorSession — TranslateAsync(string) / batch TranslateAsync(IReadOnlyList<string>)
• ITranslatorCacheService — wrap a raw session via WrapSessionAsync (exact/TTL settings on Memory)
• Failures surface as LocalizedException for host UI
• UI strings for engines/cache: en, ru, zh-Hans, uk, de, pt, ja, ko, fr, tr, pl

There is no separate InitializeAsync: create a session with defaults or an explicit settings dictionary.

Quick start (Google + Memory cache)

using Zaya.Translator.Impl.Google;
using Zaya.TranslatorCache.Impl.Memory;

using var translator = new GoogleTranslatorService();
using var cache = new MemoryTranslatorCacheService();

using var raw = await translator.CreateSessionAsync(new Dictionary<string, object>
{
    ["autoDetectLanguage"] = true,
    ["targetLanguage"] = "ru",
});
using var session = await cache.WrapSessionAsync(raw, new Dictionary<string, object>
{
    ["enableCache"] = true,
});

var text = await session.TranslateAsync("Hello, world!");
Console.WriteLine(text);

Or DI:

services.AddGoogleTranslator();
// services.AddYandexTranslator();
services.AddMemoryTranslatorCache();

Engine lifecycle

Resolve ITranslatorService (new / DI / Activator on entryPoint)
  → CreateSessionAsync(settings)
Resolve ITranslatorCacheService
  → WrapSessionAsync(rawSession, cacheSettings)
  → TranslateAsync(...)
  → Dispose session / services

Google / Yandex notes

• Both engines accept a hidden userAgent setting (default Chrome desktop UA) for HTTP requests.
• Google batch mode wraps segments as ([…]) when the text does not already contain those markers.
• Yandex: useApiKey = false → free browser endpoint (unofficial); useApiKey = true → Yandex Cloud Translate API v2.
• Yandex exposes a single Chinese code (zh); the UI shows one Chinese option (not Simplified/Traditional separately).
