  • Culprit tracking : improved lazy marking for better GUI performance

    Creator:
    Atwood, John Wesley
    Abstract:
    Culprit Tracking is a technique to make lazy evaluation in a programming language even lazier. We sought to develop such a technique after noting poorly-distributed performance characteristics of graphical user interfaces (GUIs) programmed in lazy languages. A characteristic aspect of GUI programs is the intensive screen I/O. These programs are...

  • Generalizing abstractions in form-based visual programming languages : from direct manipulation to static representation

    Creator:
    Yang, Sherry
    Abstract:
    We believe concreteness, direct manipulation and responsiveness in a visual programming language increase its usefulness. However, these characteristics present a challenge in generalizing programs for reuse, especially when concrete examples are used as one way of achieving concreteness. In this thesis, we present a technique to solve this problem by...

  • Graphical definitions : expanding spreadsheet languages through direct manipulation and gestures

    Creator:
    Gottfried, Herkimer John
    Abstract:
    Until now, attempts to extend the one-way constraint evaluation model of the spreadsheet paradigm to support complex objects, such as colored circles or user-defined types, have led to approaches featuring either a direct way of creating objects graphically or strong compatibility with the spreadsheet paradigm, but not both. This inability...

  • The expressive power and declarative attributes of exception handling in Forms/3

    Creator:
    Agrawal, Anurag
    Abstract:
    Exception handling is a programming language feature that can help increase the reliability of programs. However, not much work has been done on exception handling in visual programming languages. We present an approach for improving the exception handling mechanism in Forms/3, a declarative visual programming language based on the spreadsheet...

  • Similarity inheritance : a model of inheritance for declarative visual programming languages

    Creator:
    Djang, Rebecca W. (Rebecca Walpole)
    Abstract:
    Declarative visual programming languages (VPLs), including spreadsheets, make up a large portion of both research and commercial VPLs. Spreadsheets in particular enjoy a wide audience, including end users. Unfortunately, spreadsheets and most other declarative VPLs still suffer from some of the problems that have been solved in other languages, such...

  • Guarantees and requirements : implementation and complexity analysis of a new model of types for declarative visual programming languages

    Creator:
    Chen, Roger Ding-Fu
    Abstract:
    Djang et al. [1998] introduced a new model of types for declarative visual programming languages (VPLs). Implicit static typing is used in their type model, in order to eliminate the programming mechanisms associated with type declarations, provide immediate visual feedback with respect to type errors and guarantee type safe programs....

  • A methodology for testing spreadsheet grids

    Creator:
    Sheretov, Andrei
    Abstract:
    Although there has been research into ways to design spreadsheet systems to improve the processes of creating new spreadsheets and of understanding existing ones, little attention has been given to helping users of these environments test their spreadsheets. To help address this need, we introduce two visual approaches to testing...

  • An integrated testing and fault localization methodology for spreadsheet languages

    Creator:
    Reichwein, James
    Abstract:
    Spreadsheet languages, which include commercial spreadsheets and various research systems, have proven to be flexible tools in many settings. Research shows, however, that spreadsheets often contain faults. This thesis presents an integrated testing and fault localization methodology for spreadsheets. This methodology allows spreadsheet developers to engage in modeless development, testing...

  • Extensions to the WYSIWYT methodology

    Creator:
    Ren, Bing
    Abstract:
    Researchers in the Forms/3 group have previously developed the WYSIWYT methodology, exploring a way of systematically testing spreadsheet languages. The previous work presented the WYSIWYT methodology for individual spreadsheet cells, and later partially extended it to large grids in which some cells share the same formula. The Forms/3 spreadsheet language...

    Creator:
    Chekka, Sudheer Kumar
    Abstract:
    E-commerce has begun to evolve beyond simple web pages to more sophisticated ways of conducting e-business transactions, such as through electronic advertising, negotiation, and delivery. However, to participate in these advances requires the skills of professional programmers, and end-user owners of small businesses often cannot justify this expense. In this...
