Lightweight Project Fluent localisation manager with automatic locale fallback.

Installation

pip install fluent-manager

Features

• Supports multiple preferred locales in priority order

Directory structure

locales/
├── en/
│   └── messages.ftl
├── uk/
│   └── messages.ftl
└── pl/
    └── messages.ftl

Usage

from fluent_manager import FluentManager

lang_manager = FluentManager(
    locales=["uk", "pl"],
    locales_path="/path/to/locales",
    default_locale="en",
)

# Returns localised string in the first matching locale
message = lang_manager.get("welcome-message", user_name="Andrii")

Fallback behaviour

Situation	Result
Key exists in first preferred locale	Renders in first preferred locale
Key missing in first locale, exists in next	Renders in next preferred locale
Key exists only in default locale	Renders in default locale
Key missing in all locales	Returns the key itself
