🌍 Easy AI18n

Easy AI18n is a modern internationalization tool library for Python3. It supports AI translation, multi-user scenarios, and full string formatting syntax, making globalization of your project more elegant and natural.

✨ Key Features:

• 🚀 Easy to Use: Implement i18n with just a few lines of code
• ✨ Elegant Syntax: Use _() to wrap translatable texts, seamlessly integrating into your code
• 🤖 AI Translation: Supports translation using large language models (LLMs) for high-quality results
• 📝 Full Formatting Support: Fully supports all Python string formatting syntaxes
• 🌐 Multi-language Support: Choose languages using [] selector for multilingual support

🔍 Comparison with Other i18n Tools

Other i18n Tools	EasyAI18n
Requires manual maintenance of keys and i18n files, high development cost	Automatically extracts translation content, no manual file maintenance needed
Supports only partial formatting syntax	Fully supports all formatting syntax
No real-time multi-language switching, unsuitable for multi-user scenarios	Supports default language and multi-language switching, adaptable to multi-user environments

⚡ Quick Start

📦 Installation

pip install easy-ai18n

🧪 Simple Example

/i18n.py

from easy_ai18n import EasyAI18n

i18n = EasyAI18n()

_ = i18n.t()

if __name__ == "__main__":
    i18n.build(["ja"])

/main.py

from i18n import _


def main():
    print(_("Hello, world!")['ja'])


if __name__ == "__main__":
    main()

📘 Usage Tutorial

🛠️ Custom Translation Function Names

from easy_ai18n import EasyAI18n

i18n = EasyAI18n(
    func_name=["_t", '_']  # Custom translation function names
)

_t = i18n.t()
_ = _t

print(_t("Hello, world!"))
print(_("Hello, world!"))

🤖 Use AI for Translation

from easy_ai18n import EasyAI18n
from easy_ai18n.translator import OpenAIYAMLTranslator

translator = OpenAIYAMLTranslator(api_key=..., base_url=..., model='gpt-4o-mini')

i18n = EasyAI18n()
i18n.build(target_lang=["ru", "ja", 'zh-Hant'], translator=translator)

_ = i18n.t()

print(_("Hello, world!")['zh-Hant'])

👥 Multi-user Language Scenarios (e.g. Telegram Bot)

Use custom language selector to dynamically select languages in multi-user environments:

/i18n.py:

from pyrogram.types import Message
from easy_ai18n import EasyAI18n, PostLanguageSelector


class MyPostLanguageSelector(PostLanguageSelector):
    def __getitem__(self, msg: Message):
        # ......
        lang = msg.from_user.language_code
        return super().__getitem__(lang)


i18n = EasyAI18n()

_ = i18n.t(post_lang_selector=MyPostLanguageSelector)

if __name__ == "__main__":
    i18n.build(target_lang=['en', 'ru'])

/bot.py:

from pyrogram import Client
from pyrogram.types import Message
from i18n import _

bot = Client("my_bot")


@bot.on_message()
async def start(__, msg: Message):
    await msg.reply(_[msg]("Hello, world!"))


if __name__ == "__main__":
    bot.run()
