  • Design and Application of Variational Representations

    Creator:
    Smeltzer, Karl J.
    Abstract:
    Variability is an important and widely studied topic across domains such as version control, software product lines, and metaprogramming. This dissertation presents an investigation into the process of systematically adding variability to data structures and programs, leading to guidelines for variational data structures and implications for programs that create, manipulate,...

  • A Formal Foundation for Variational Programming Using the Choice Calculus

    Creator:
    Hubbard, Spencer
    Abstract:
    In this thesis, we present semantic equivalence rules for an extension of the choice calculus and sound operations for an implementation of variational lists. The choice calculus is a calculus for describing variation and the formula choice calculus is an extension with formulas. We prove semantic equivalence rules for the...

  • The choice calculus : a formal language of variation

    Creator:
    Walkingshaw, Eric
    Abstract:
    In this thesis I present the choice calculus, a formal language for representing variation in software and other structured artifacts. The choice calculus is intended to support variation research in a way similar to the lambda calculus in programming language research. Specifically, it provides a simple formal basis for presenting,...

  • View-based editing of variational code

    Creator:
    Van de Wetering, Miles
    Abstract:
    This paper discusses the merits of providing users variational views when editing variational code. I provide a plugin for the popular Atom Integrated Development Environment (IDE) which replaces #ifdef annotations commonly used by the C PreProcessor (CPP) with colored backgrounds, thus reducing code clutter and attempting to help programmers quickly...

  • Representing Program Edits with the Choice Calculus

    Creator:
    Xu, Keying
    Abstract:
    The problem of supporting more advanced selective undo operations has received a lot of attention. However, selective undo is generally missing in commonly used editors. Moreover, partial selective undo, the ability of undoing just part of some edit so that other edits may be undone, is not supported at all....

  • Variational Typing and Its Applications

    Creator:
    Chen, Sheng
    Abstract:
    The study of variational typing originated from the problem of type inference for variational programs, which encode numerous different but related plain programs. In this dissertation, I present a sound and complete type inference algorithm for inferring types of all plain programs encoded in variational programs. The proposed algorithm runs...

  • Variational Satisfiability Solving

    Creator:
    Young, Jeffrey M.
    Abstract:
    Over the last two decades, satisfiability and satisfiability-modulo theory (SAT/SMT) solvers have grown powerful enough to be general purpose reasoning engines throughout software engineering and computer science. However, most practical use cases of SAT/SMT solvers require not just solving a single SAT/SMT problem, but solving sets of related SAT/SMT problems....

  • Imperative Programming with Variational Effects

    Creator:
    Grasley, Alexander B.
    Abstract:
    Variation is a commonly encountered element of modern software systems. Recent research into variation has led to increasing interest in the development of variational programming languages and corresponding variational models of execution. Variational imperative languages pose a particular challenge due to the complex interactions between side effects and variation. The...

  • Implementation Techniques for Variational Data Structures

    Creator:
    Meng, Meng
    Abstract:
    Many applications require not only representing variability in software and data, butalso computing with it. To do so efficiently requires variational data structures thatmake variability explicit in the underlying data and the operations used to manipulate it.Variational data structures have been developed ad hoc for many applications, but thereis little...

    Abstract:
    Appropriate representations of variational software simplify the analysis of their properties.This thesis proposes tailored representations of two kinds variational softwares: difference files of merge commits in Git and feature models. For the former, we use the Choice Edit Model, which is based on the choice calculus, to represent changes introduced...
