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.

「但之後你開始出去，看到鯨魚、海豹、搭船前往小島，然後坐小型飛機短途飛行。你會想：『這真是太棒了。』今年，我非常幸運地看到了一個帝企鵝族群。那景象就像大衛·艾登堡（David Attenborough）紀錄片裡的一樣。」

В среднем первая декада марта финиширует с положительной температурной аномалией в 2-3 градуса. Вторая декада марта будет менее теплой и по своей температуре окажется близкой к климатической норме, что также не способствует бурному таянию снега. В третей декаде первого весеннего месяца возможны возвраты холодов.
