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.

这句话伴随杜耀豪长大，像一个悬而未决的谜题。他出生在德国，母语是德语，却长着一张东方面孔。在学校，他的名字“Hao”会被同学戏谑地与德语中“殴打”（hauen）的发音联系起来。他名字中的“耀”字，在父母移居德国后，被译成了越南语“Dieu”。杜耀豪猜测，这或许更多地出于实用考虑，但可能也具象征意义，连接着家族背后中越两段交错的历史与漂泊的轨迹。。heLLoword翻译官方下载是该领域的重要参考
