This publication constitutes the completely refereed post-proceedings of the 4th overseas convention on software program Language Engineering, SLE 2011, held in Braga, Portugal, in July 2011.
The 18 papers awarded including four tool/language demonstration papers have been rigorously reviewed and chosen from various submissions. SLE’s optimum challenge is to inspire and arrange conversation among groups that experience generally checked out software program languages from varied, extra really good, and but complementary views. SLE emphasizes the elemental thought of languages in preference to any recognition in particular technical spaces.

Software architecture—the conceptual glue that holds each part of a venture jointly for its many stakeholders—is widely known as a serious aspect in smooth software program improvement. Practitioners have more and more stumbled on that shut consciousness to a software program system’s structure can pay beneficial dividends. with no an structure that's acceptable for the matter being solved, a undertaking will stumble alongside or, probably, fail. regardless of a good structure, if that structure isn't good understood or good communicated the venture is not going to succeed.
Documenting software program Architectures, moment variation, presents the main whole and present counsel, autonomous of language or notation, on tips to catch an structure in a quite often comprehensible shape. Drawing on their vast event, the authors first assist you come to a decision what info to record, after which, with directions and examples (in a number of notations, together with UML), allow you to exhibit an structure in order that others can effectively construct, use, and preserve a process from it. The booklet good points ideas for sound documentation, the targets and techniques of documentation, architectural perspectives and kinds, documentation for software program interfaces and software program habit, and templates for taking pictures and organizing details to generate a coherent package deal. New and enhanced during this moment edition:
* insurance of architectural types equivalent to service-oriented architectures, multi-tier architectures, and information models
* Deeper therapy of documentation of cause, reflecting most sensible business practices
* enhanced templates, reflecting years of use and suggestions, and extra documentation structure options
* a brand new, entire instance (available online), that includes documentation of an internet service-oriented system
* Reference courses for 3 vital structure documentation languages: UML, AADL, and SySML
This ebook constitutes a suite of the easiest papers chosen from nine workshops and a couple of symposia held at the side of types 2009, the 12 foreign convention on version pushed Engineering Languages and platforms, in Denver, CO, united states, in October 2009. the 1st sections comprise chosen papers from the Doctoral Symposium and the tutorial Symposium, respectively.

Nesting modules or connecting them by means of context references is a suﬃcient deﬁnition for context composition. The execution of model transformations ﬁrst requires the manual instantiation of modules into concrete application contexts (between concrete modeling artifacts), which implies the instantiation of data-ﬂow compositions. Second, for a set of instantiated modules, the execution engine automatically applies the represented model transformations in the required sequence determined by the data-ﬂow composition.
Epsilon allows black-box data-ﬂow composition of Epsilon tasks, deﬁned in E* languages20 or additional languages like ATL21 . The data-ﬂow composition is implemented with Ant22 scripts. In addition, Epsilon provides its own transformation language ETL. Within ETL, context compositions are possible. However, context compositions are not possible with other transformation languages as ETL and, as in the two approaches above, the traceability information of the context composition has to be interpreted by the transformation.
Comments and whitespace. This is especially relevant in the context of refactorings, which produce source code for human consumption. In this paper, we present an algorithm for fully automatic source code reconstruction for source-to-source transformations. The algorithm preserves the layout and comments of the unaffected parts and reconstructs the indentation of the affected parts, using a set of clearly defined heuristic rules to handle comments. 1 Introduction The successful development of new languages is currently hindered by the high cost of tool building.
