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.
「很多人認為，只要用一些神奇的詞語，就能讓大型語言模型解決問題，」美國范德比爾特大學（Vanderbilt University）研究生成式AI的電腦科學教授朱爾斯·懷特（Jules White）說，「但關鍵不在於用詞，而在於你如何從根本上表達你想要做的事情。」
