Project description
📂 LDT Nexus
LDT Nexus — это сверхбыстрое ядро на Rust для управления настройками и локализацией в Python-приложениях. Вдохновлено QSettings, но усилено асинхронностью, сигналами и высокой производительностью[cite: 4].
✨ Почему Nexus?
- Rust Core: Обработка данных и нормализация путей на стороне Rust.
- Многопоточность: Параллельная загрузка файлов конфигурации и переводов.
- Реактивность: Полная поддержка сигналов через
psygnalдля мгновенного обновления UI. - Гибкость драйверов: Поддержка JSON, JSON5, TOML, YAML и Memory-режима из коробки.
⚙️ LdtSettings: Управление конфигурацией
LdtSettings — это основное хранилище, которое заменяет стандартные парсеры конфигов.
Базовое использование
from ldt.nexus import LdtSettings
# Автоматический sync() на диск при выходе из контекста
with LdtSettings("config.toml", driver="toml") as cfg:
cfg.setValue("ui.theme", "dark")
cfg.setValue("window.size", [1920, 1080])
# Доступ через группы (аналог QSettings)
with cfg.localGroups("editor", "font"):
cfg.setValue("family", "Fira Code") # Итоговый ключ: editor/font/family
Реактивность и Сигналы
Вы можете подписаться на изменения в конфиге, чтобы ваш код реагировал на них автоматически.
cfg = LdtSettings("settings.json")
# Сигнал срабатывает при каждом изменении ключа
cfg.signals.valueChanged.connect(lambda key, val: print(f"Update: {key} = {val}"))
# Массовое обновление без лишних сигналов
with cfg.blockSignals():
cfg.update(theme="light", language="ru")
🌍 LdtTranslator: Реактивная локализация
Новый модуль для работы с переводами, построенный на базе LdtSettings в памяти.
Параллельная загрузка и кэширование
Переводчик умеет загружать десятки файлов локализации параллельно, используя все ядра процессора.
from ldt.nexus.engine import LdtTranslator
translator = LdtTranslator("locales/")
translator.load(parallel=True) # Быстрая загрузка через ThreadPoolExecutor
# Использование сигналов смены языка
translator.signals.language_changed.connect(lambda lang: print(f"Язык изменен на {lang}"))
translator.set_lang("ru")
print(translator.tr("app.title")) # Поддержка контекста и переменных
Поддержка Плюралов (Множественные числа)
# 'apples': {'1': '{n} яблоко', '2': '{n} яблока', '5': '{n} яблок'}
print(translator.plural("apples", 21)) # 21 яблоко
🛠 Возможности ядра
| Особенность | Описание |
|---|---|
| Normalizer | Автоматическая замена . на / в путях на уровне Rust. |
| Drivers | JSON, JSON5, TOML, YAML, Memory. |
| Serializers | Регистрация кастомных типов через @LdtSettings.register_type. |
| Caching | Встроенный TTLCache в переводчике для мгновенного доступа к UI-строкам. |
🚀 Установка
# Базовая версия
pip install ldt-nexus
# С поддержкой сигналов
pip install ldt-nexus[signals]
