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.

«Стакан апельсинового фреша 250 мл это 100–130 ккал. Облепиховый напиток с медом 300–400 миллиграмм это 150–250 килокалорий. Смузи из банана, ягод, йогурта и меда это 200–350 килокалорий. Модный боул с фруктами, гранолой, орехами и медом легко тянет на 400–700 килокалорий. И все это поверх обычной еды, а не вместо», — сказал эксперт.
