Abstract:Package managers are legion. Every programming language and operating system has its own solution, each with subtly different semantics for dependency resolution. This fragmentation prevents multilingual projects from expressing precise dependencies across language ecosystems; it leaves external system and hardware dependencies implicit and unversioned; it obscures security vulnerabilities that lie in the full dependency graph. We present the \textit{Package Calculus}, a formalism for dependency resolution that unifies the core semantics of diverse package managers. Through a series of formal reductions, we show how this core is expressive enough to model the diversity that real-world package managers employ in their dependency expression languages. By using the Package Calculus as the intermediate representation of dependencies, we enable translation between distinct package managers and resolution across ecosystems.

人的智能有三个方面：信息的收集、信息的处理产生认知、基于认知的行动。大语言模型目前主要的应用形态是ChatGPT这样的聊天机器人（Chatbot），能力集中在前两个方面。但更加有用的机器智能不只停留在“理解”和“说话”，如果能像一个或一群优秀的人才那样帮我们“做事”，显然能创造更大的价值。这就需要AI智能体（Agent）。，推荐阅读heLLoword翻译官方下载获取更多信息
