What it is and what it does
i18nice is a translation library for Python that brings Rails-style i18n functionality to Python applications. It allows you to store translations in YAML or JSON files, organize them by locale and namespace, and retrieve translated strings at runtime with support for dynamic placeholders and pluralization rules.
The library handles common i18n patterns: you define translations either programmatically or via files, set a current locale, and call the translation function to fetch translated strings. It supports fallback locales when a translation is missing, lazy-loads translation files to avoid unnecessary I/O, and provides configuration options for different file structures and naming conventions. With no external runtime dependencies, it is lightweight and easy to integrate into existing Python projects.
Use it for
- Build a web application that serves content in multiple languages with locale-specific fallbacks
- Add pluralization rules to user-facing messages (e.g., 'You have 1 mail' vs. 'You have 5 mails')
- Manage translations for a CLI tool or desktop application using YAML or JSON files
- Organize translations hierarchically by feature or module using directory and file namespaces
- Store and retrieve translated strings with placeholder substitution for dynamic content
