Domain-specific Language Integration with Compile-time Parser Generator Library

ACM SIGPLAN NOTICES 2011年第2期46卷 137-146页

作者： Porkolab, Zoltan Sinkovics, Abel Eotvos Lorand Univ Dept Programming Languages & Compilers H-1117 Budapest Hungary

Smooth integration of domain-specific languages into a general purpose host language requires absorbing of domain code written in arbitrary syntax. the integration should cause minimal syntactical and semantic overhead and introduce minimal dependency on external tools. In this paper we discuss a DSL integration technique for the C++ programming language. the solution is based on compile-time parsing of the DSL code. the parser generator is a C++ template metaprogram reimplementation of a runtime Haskell parser generator library. the full parsing phase is executed when the host program is compiled. the library uses only standard C++ language features, thus our solution is highly portable. As a demonstration of the power of this approach, we present a highly efficient and type-safe version of printf and the way it can be constructed using our library. Despite the well known syntactical difficulties of C++ template metaprograms, building embedded languages using our library leads to self-documenting C++ source code.

international conference on Distributed Computing Systems Workshop

作者： D. Wagelaar System and Software Engineering Laboratory Vrije Universiteit Brussel Brussels Belgium

Portable and embedded devices form an increasingly large group of computers, often referred to as ambient intelligence (AmI). this new variety in computing platforms cause a corresponding diversity in software/hardware platforms and other context factors. component-based middleware platforms offer a uniform environment for software, but they do not take away specific context differences, such as hardware resources, user identity/role and logical/physical location. Specialised component versions and/or configurations have to be made for each computing context if that computing context is to be used to its full extent. this is because the fine differences between component versions cannot be separated into finer components with the current component models. Aspect-oriented programming and generative programming technologies can be used to provide the fine-grained modularity that is necessary. In addition, the diversity of component-based platforms themselves form an extra reason for different component versions. We propose using a context-driven framework for the development of AmI components, which is based upon a gradual refinement mechanism. this refinement mechanism can cope with the course-grained differences between component models as well as the fine-grained differences between computing configurations.

Tutorial on Generative Software Development

international Software Product Line conference (SPLC)

作者： K. Czarnecki University of Waterloo Canada

Software product line engineering (SPLE) [5] seeks to exploit the commonalities among systems from a given problem domain while managing the variabilities among them in a systematic way. In SPLE, new system variants can be rapidly created based on a set of reusable assets, such as a common architecture, components, and models. generative software development [6] aims at modeling and implementing product lines in such a way that a given system can be automatically generated from a specification written in one or more textual or graphical domain-specific languages (DSLs) [13, 4, 15, 8, 3, 1, 12, 14].

Code Clones in Feature-Oriented Software Product Lines

引用

ACM SIGPLAN NOTICES 2011年第2期46卷 103-112页

作者： Schulze, Sandro Apel, Sven Kaestner, Christian Univ Magdeburg D-39106 Magdeburg Germany Univ Passau Passau Germany Univ Marburg D-35032 Marburg Germany

Some limitations of object-oriented mechanisms are known to cause code clones (e. g., extension using inheritance). Novel programming paradigms such as feature-oriented programming (FOP) aim at alleviating these limitations. However, it is an open issue whether FOP is really able to avoid code clones or whether it even facilitates (FOP-related) clones. To address this issue, we conduct an empirical analysis on ten feature-oriented software product lines with respect to code cloning. We found that there is a considerable number of clones in feature-oriented software product lines and that a large fraction of these clones is FOP-related (i.e., caused by limitations of feature-oriented mechanisms). Based on our results, we initiate a discussion on the reasons for FOP-related clones and on how to cope with them. We show by means of examples how such clones can be removed by applying refactorings.

We present a no-reference image-quality - assessment algorithm based on active reasoning module. this algorithm has three modules: the feature extraction module, the active reasoning module, and the quality assessment module. the active reasoning module incorporates the generator component of the generative adversarial network and enhances its structure with the Res2Net architecture. By integrating this module into the backbone feature extraction network, we improve the receptive field of each convolutional layer, enabling the network to capture information at different scales of the image. To preserve the texture information of the image, we input the gradient map of the distorted image, the distorted image itself, and the image features generated by the generator into the quality assessment module, which has a multi-feature regression networks. this module establishes a mapping model from image-feature to image-quality scores. We conducted experimental analysis of this algorithm on three widely used public datasets, confirming the excellent performance and superiorities of the presented algorithm. the results validate the effectiveness of the designed algorithm and its ability to assess image quality accurately.

IEEE international conference on Natural Language Processing and Knowledge engineering (NLP-KE)

作者： Pawan Kumar Arun Kumar Rathaur Rashid Ahmad Mukul K Sinha Rajeev Sangal Expert Software Consultants Limited Noida India International Institute of Information Technology Hyderabad India

the paper presents a software integration, testing and visualization tool, called Dashboard, which is based on pipe-lined backboard architecture for family of natural language processing (NLP) application. the Dashboard helps in testing of a module in isolation, facilitating the training and tuning of a module, integration and testing of a set of heterogeneous modules, and building and testing of complete integrated system as well. It is also equipped with a user-friendly visualization tool to build, test, and integrate a system (or a subsystem) and view its component-wise performance, and step-wise processing as well. the Dashboard is being successfully used by a consortium of eleven academic institutions to develop a suite of bi-directional machine translation (MT) system for nine pairs of Indic languages, and six MT systems have already been deployed on web. the MT systems are being developed by reusing / re-engineering previously developed NLP modules, by different institutions, in different programming languages, using Dashboard as the testing and integration tool. the paper also discusses the experiences of developing MT products in consortium mode, using Dashboard as its integrating and testing platform, and its proposed enhancements.

Composition of Dynamic Analysis Aspects

引用

ACM SIGPLAN NOTICES 2011年第2期46卷 113-122页

Aspect-oriented programming provides a convenient high-level model to define several kinds of dynamic analyses, in particular thanks to recent advances in exhaustive weaving in core libraries. Casting dynamic analyses as aspects allows the use of a single weaving infrastructure to apply different analyses to the same base program, simultaneously. However, even if dynamic analysis aspects are mutually independent, their mere presence perturbates the observations of others: this is due to the fact that aspectual computation is potentially visible to all aspects. Because current aspect composition approaches do not address this kind of computational interference, combining different analysis aspects yields at best unpredictable results. It is also impossible to flexibly combine various analyses, for instance to analyze an analysis aspect. In this paper we show how the notion of execution levels makes it possible to effectively address these composition issues. In order to realize this approach, we explore the practical and efficient integration of execution levels in a mainstream aspect language, AspectJ. We report on a case study of composing two out-of-the-box analysis aspects in a variety of ways, highlighting the benefits of the approach.

At thales Defense Mission Systems, software products first go through an industrial prototyping phase. We elaborate evolutionary prototypes which implement complete business behavior and fulfill functional requirements. We elaborate and evolve our solutions directly with end-users who act as stake-holders in the products' design. Prototypes also serve as models for the final products development. Because software products in the defense industry are developed over many years, this prototyping phase is crucial. therefore, reusing software is a high-stakes issue in our activities. component-oriented development helps us to foster reuse throughout the life cycle of our products. the work presented in this paper stems from 15 years of experience in developing prototypes for the defense industry. We directly reuse component implementations to build new prototypes from existing ones. We reuse component interfaces transparently in multiple prototypes, whatever the underlying implementation solutions. this kind of reuse spans prototypes and final products which are deployed on different execution platforms. We reuse non-component legacy software that we integrate in our component architectures. In this case, we seamlessly augment standard classes with component behavior, while preserving legacy code. In this paper, we present our component programming framework with a focus on component reuse in the context of evolutionary prototyping. We report three scenarios of reuse that we encounter regularly in our prototyping activity.
