Static Typing of Complex Presence Constraints in Interfaces

Authors: Nathalie Oostvogels, Joeri De Koster, and Wolfgang De Meuter

Published in: LIPIcs, Volume 109, 32nd European Conference on Object-Oriented Programming (ECOOP 2018)

Abstract
Many functions in libraries and APIs have the notion of optional parameters, which can be mapped onto optional properties of an object representing those parameters. The fact that properties are optional opens up the possibility for APIs and libraries to design a complex "dependency logic" between properties: for example, some properties may be mutually exclusive, some properties may depend on others, etc. Existing type systems are not strong enough to express such dependency logic, which can lead to the creation of invalid objects and accidental usage of absent properties. In this paper we propose TypeScriptIPC: a variant of TypeScript with a novel type system that enables programmers to express complex presence constraints on properties. We prove that it is sound with respect to enforcing complex dependency logic defined by the programmer when an object is created, modified or accessed.

Static Typing of Complex Presence Constraints in Interfaces (Artifact)

Authors: Nathalie Oostvogels, Joeri De Koster, and Wolfgang De Meuter

Published in: DARTS, Volume 4, Issue 3, Special Issue of the 32nd European Conference on Object-Oriented Programming (ECOOP 2018)

Abstract
This artifact is based on TypeScriptIPC, a statically typed programming language with interfaces in which complex presence constraints can be defined. This enables developers to express inter-property constraints on interface properties. The need for these inter-property constraints stems from web APIs, which often impose a complex "dependency logic" between properties. For example, some properties may be mutually exclusive, or the presence of a property may depend on the presence of others, etc. TypeScriptIPC is a variant of TypeScript, in which interfaces are extended to express constraints over multiple properties, using propositional logic. This artifact contains documentation on how to build and run TypeScriptIPC, such that the code snippets from the paper can be run.
