Programming languages are complex systems that are usually implemented as monolithic interpreters and compilers. In recent years, researchers and practitioners gained interest in product line engineering to improve the reusability of language assets and the management of variability-rich systems, introducing the notions of language workbenches and language product lines (LPLs). Nonetheless, language development remains a complex activity and design or implementation flaws can easily waste the efforts of decomposing a language specification into language features. Poorly designed language decompositions result in high inter-dependent components, reducing the variability space of the LPL system and its maintainability. One should detect and fix the design flaws posthaste to prevent these risks while minimizing the development overhead. Therefore, various aspects of the quality of a language decomposition should be quantitatively measurable through adequate metrics. The evaluation, analysis and feedback of these measures should be a primary part of the engineering process of a LPL. In this paper, we present an exploratory study trying to capture these aspects by introducing a design methodology for LPLs; we define the properties of a good language decomposition and adapt a set of metrics from the literature to the framework of language workbenches. Moreover, we leverage the LPL engineering environment to perform an empirical evaluation of 26 -based LPLs based on this design methodology. Our contributions form the foundations of a design methodology for -based LPLs. This methodology is comprised of four different elements: i) an engineering process that defines the order in which decisions are made, ii) an integrated development environment for LPL designers and iii) some best practices in the design of well-structured language decomposition when using , supported by iv) a variety of LPL metrics that can be used to detect errors in design decisions.

“…Oliveira et al [20] propose a metric suite to support evaluation of product line architectures based on McCabe's cyclomatic complexity of their core components, which is computed using the control flow graph of the program and measures the number of linearly independent paths through a program's source code. Her et al [10] suggest a metric to measure reusability of product line core assets based on their ability to provide functionality to many products of the same SPL, the number of SPL variation points that are realized by an asset, the number of replaceable components in a core asset and more. Hoek et al [28] describe metrics for measuring service utilization of SPL components based on the percentage of provided and required services of a component.…”

Abstract. In this paper, we consider the problem of refactoring related software products specified in UML into annotative product line representations. Our approach relies on identifying commonalities and variabilities in existing products and further merging those into product line representations which reduce duplications and facilitate reuse. Varying merge strategies can lead to producing several semantically correct, yet syntactically different refactoring results. Depending on the goal of the refactoring, one result can be preferred to another. We thus propose to capture the goal using a syntactic quality function and use that function to guide the merge strategy. We define and implement a quality-based mergerefactoring framework for UML models containing class and statechart diagrams and report on our experience applying it on three case-studies.

Software Product Line (SPL) is an approach for de facto reusing of software artifacts for a given domain. Amongst the artifacts developed in the context of SPL is the Product-Line Architecture (PLA). It is one of the central artifacts of the SPL core assets responsible for abstracting a common architecture for specific products. Organizations should continuously evaluate the quality of their products by managing their PLA evolution and variabilities. Thus, the PLA evaluation should be taken into consideration as one of the most important activities throughout a SPL life cycle. Existing literature presents different PLA evaluation methods, from which metrics are most used. Thus, metrics allow different PLA quality attributes to be prioritized when deriving existing products, most of the time by trading-off them. Size, Coupling and Cohesion are examples of important attributes related to Maintainability from ISO/IEC 25010. Metrics for size, coupling and cohesion have successfully been applied in SPL, however, not taking into account commonalities and variabilities. Therefore, this paper proposes metrics for measuring Size, Coupling and Cohesion of PLA, as well as their experimental validations. Such validations are performed correlating the values collected for each metric to participants rating for each quality attribute. Results indicate a weak positive correlation for the size and coupling metrics and a weak negative correlation for the Cohesion metric. In view of the presented evidence, new studies and/or investigations must be carried out to make results generalizable.
