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.
Hot-reloading automatically converts global and module-local variables to use the heap, then automatically inserts dereferences whenever they are accessed. This allows the programmer to make changes to functions and dynamically reload them without losing state. This feature is excellent for facilitating iterative, low-latency development. Add that to the build system, and you have a fast, simple, and convenient development environment。关于这个话题，新收录的资料提供了深入分析
