multi_language.py

"""
    Translate this project to other languages (experimental, please open an issue if there is any bug)
    
    
    Usage:
        1. modify config.py, set your LLM_MODEL and API_KEY(s) to provide access to OPENAI (or any other LLM model provider)

        2. modify LANG (below ↓)
            LANG = "English"

        3. modify TransPrompt (below ↓)
            TransPrompt = f"Replace each json value `#` with translated results in English, e.g., \"原始文本\":\"TranslatedText\". Keep Json format. Do not answer #."

        4. Run `python multi_language.py`. 
            Note: You need to run it multiple times to increase translation coverage because GPT makes mistakes sometimes.
           (You can also run `CACHE_ONLY=True python multi_language.py` to use cached translation mapping)

        5. Find the translated program in `multi-language\English\*`
   
    P.S.
    
        - The translation mapping will be stored in `docs/translation_xxxx.json`, you can revised mistaken translation there.
        
        - If you would like to share your `docs/translation_xxxx.json`, (so that everyone can use the cached & revised translation mapping), please open a Pull Request

        - If there is any translation error in `docs/translation_xxxx.json`, please open a Pull Request
        
        - Welcome any Pull Request, regardless of language
