分享一下我过去几个月和 Claude 一起合作用 Rust 开发的新一代编程语言 AIScript！

我过去几个月在和 Claude 合作使用 Rust 开发了一门新语言 AIScript，现在正式开源。这门语言最大的特点是内置 AI 特性以及把语言和 Web 框架合二为一。

在 AIScript 里 prompt/ai/agent 都是关键字，使用 prompt "text" 就可以跟 AI 交互，任何使用了 prompt 的函数都需要显示声明是 ai 函数。定义一个 agent 跟定义一个 class 一样简单，支持类似 OpenAI Swarm 那种多 agent 编排。

只需要使用简单明了的 DSL 就可以写 web 接口，并且自动生成 OpenAPI docs ，JWT 或者 Google 社交账号登录用一个 @auth 或 @sso 指令即可。

$ export OPENAI_API_KEY=<your-openai-api-key>

$ cat web.ai
get / {
    """An api to ask LLM"""

    query {
        """the question to ask"""
        @string(min_len=3, max_len=100) // validate params with builtin directive @string
        question: str
    }

    // `ai` and `prompt` are keywords
    ai fn ask(question: str) -> str {
        let answer = prompt question;
        return answer;
    }

    // use query.name or query["name"] to access query parameter
    let answer = ask(query.question);
    return { answer };
}

$ aiscript serve web.ai
Listening on http://localhost:8080

$ curl http://localhost:8080
{
    "error": "Missing required field: question"
}

$ curl http://localhost:8080?question=Hi
{
    "error": "Field validation failed: question: String length is less than the minimum length of 3"
}

$ curl http://localhost:8080?question=What is the capital of France?
{
    "answer": "The capital of France is Paris."
}

agent Researcher {
    instructions: "You are a research assistant...",
    
    fn search_web(query: str) -> str {
        """
        Search the web for information about a topic.
        """
        // Implementation
        return "search results";
    }
    
    fn save_notes(content: str) -> bool {
        """
        Save notes about a topic.
        """
        // Implementation
        return true;
    }
}

@sso(provider="google")
get /auth/google {
    let url = sso.authority_url();
    print(url);
    return temporary_redirect(target=url);
}

@sso(provider="google")
get /auth/google/callback {
    query {
        code: str,
        state: str,
    }

    print("code", query.code);
    print("state", query.state);
    let user_info = sso.verify(code=query.code);
    print(user_info);
    return { user_info };
}
