Composing Software

All software design is composition: the act of breaking complex problems down into smaller problems and composing those solutions. Most developers have a limited understanding of compositional techniques. It's time for that to change.In "Composing Software", Eric Elliott shares the fundamentals of composition, including both function composition and object composition, and explores them in the context of JavaScript. The book covers the foundations of both functional programming and object oriented programming to help the reader better understand how to build and structure complex applications using simple building blocks.You'll learn: Functional programmingObject compositionHow to work with composite data structuresClosuresHigher order functionsFunctors (e.g., array.map)Monads (e.g., promises)TransducersLensesAll of this in the context of JavaScript, the most used programming language in the world. But the learning doesn't stop at JavaScript. You'll be able to apply these lessons to any language. This book is about the timeless principles of software composition and its lessons will outlast the hot languages and frameworks of today. Unlike most programming books, this one may still be relevant 20 years from now.This book began life as a popular blog post series that attracted hundreds of thousands of readers and influenced the way software is built at many high growth tech startups and fortune 500 companies

Software components and component-based software development (CBSD) are acknowledged as the best approach for constructing quality software at reasonable cost. Composing Software Components: A Software-testing Perspective describes a 10-year investigation into the underlying principles of CBSD. By restricting attention to the simplest cases, startling results are obtained: • Components are tested using only executable code. Their behavior is recorded and presented graphically. • Functional and non-functional behavior of systems synthesized from components are calculated from component tests alone. No access to components themselves is required. • Fast, accurate tools support every aspect of CBSD from design through debugging. Case studies of CBSD also illuminate software testing in general, particularly an expanded role for unit testing and the treatment of non-functional software properties. This unique book: • Contains more than a dozen case studies of fully worked-out component synthesis, with revealing insights into fundamental testing issues. • Presents an original, fundamental theory of component composition that includes persistent state and concurrency, based on functional software testing rather than proof-of-programs. • Comes with free supporting software with tutorial examples and data for replication of examples. The Perl software has been tested on Linux, Macintosh, and Windows platforms. Full documentation is provided. • Includes anecdotes and insights from the author’s 50-year career in computing as systems programmer, manager, researcher, and teacher. Composing Software Components: A Software-testing Perspective will help software researchers and practitioners to understand the underlying principles of component testing. Advanced students in computer science, engineering, and mathematics can also benefit from the book as a supplemental text and reference.

This book constitutes the refereed proceedings of the 8th International Symposium on Software Composition, SC 2009, held in Zurich, Switzerland, in July 2009. The workshop has been organized as an event co-located with the TOOLS Europe 2009 conference. The 10 revised full papers presented together with 2 invited lectures were carefully reviewed and selected from 34 submissions. The papers reflect current research in software composition to foster developing of composition models and techniques by using aspect- and service-oriented programming, specification of component contracts and protocols, methods of correct components composition, as well as verification, validation and testing techniques - even in pervasive computing environments and for the Web.

Invasive software composition as a new, component-based way to construct software systems is presented. To improve reuse, this method regards software components as greybox and integrates them during composition. Components are distinct in design, but are merged in implementations, leading to highly integrated and more efficient systems. Building on a minimal set of program transformations, composition operator libraries can be developed that parameterize, extend, connect, mediate, and aspect-weave components. Invasive software composition unifies several software engineering techniques such as generic programming, architecture systems, inheritance, and aspect-oriented programming. The book is centered around the JAVA language and a freely available demonstrator library called COMPOST. The book provides a wealth of material for researchers, students and professional software architects alike.

Composing Our Future is the ideal book for music teacher educators seeking to learn more about composition education. It provides resources to guide the development of undergraduate and graduate curricula, specific courses, professional development workshops, and environments where composition education can flourish.

Multimodal Composing provides strategies for writing center directors and consultants working with writers whose texts are visual, technological, creative, and performative—texts they may be unaccustomed to reading, producing, or tutoring. This book is a focused conversation on how rhetorical, design, and multimodal principles inform consultation strategies, especially when working with genres that are less familiar or traditional. Multimodal Composing explores the relationship between rhetorical choices, design thinking, accessibility, and technological awareness in the writing center. Each chapter deepens consultants’ understanding of multimodal composing by introducing them to important features and practices in a variety of multimodal texts. The chapters’ activities provide consultants with an experience that familiarizes them with design thinking and multimodal projects, and a companion website (www.multimodalwritingcenter.org) offers access to additional resources that are difficult to reproduce in print (and includes updated links to resources and tools). Multimodal projects are becoming the norm across disciplines, and writers expect consultants to have a working knowledge of how to answer their questions. Multimodal Composing introduces consultants to key elements in design, technology, audio, and visual media and explains how these elements relate to the rhetorical and expressive nature of written, visual, and spoken communication. Peer, graduate student, professional tutors and writing center directors will benefit from the activities and strategies presented in this guide.
