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.

书中穿插了不少诙谐故事、民俗谚语，调和了学术理论的严谨与抽象。譬如“韩延寿巧断争田案”中的“县官误解风土”，某郡太守向一县官问话：“此地风土如何？”县官不知道“风土”指的是风俗习惯，于是答道：“风不大，土沙也不乱飞。”太守又问：“黎庶还好吗？”县官更不懂“黎庶”指的是老百姓，回答说：“梨树今年开花少，估计要减产。”看似闲笔，实则暗合执法施政必须考察风土民情的道理，让读者在会心一笑中领会中华法系的吏治知识。
