  abstract: "Developing web applications is difficult since (1) the client-server relationship is asymmetric: the server cannot update clients but only responds to client requests and (2) the navigation facilities of web browsers lead to a situation where servers cannot control the state of the clients. Page-centric web application frameworks fail to offer adequate solutions to model control flow at a high-level of abstraction. Developers have to work manually around the shortcomings of the HTTP protocol. Some approaches offer better abstractions by composing an application out of components, however they still fail to offer modeling control flow at a high level. Continuation-based approaches solve this problem by providing the facilities to model a control flow over several pages with one piece of code. However combining multiple flows inside the same page is difficult. This article presents Seaside. Seaside is a framework which combines an object-oriented approach with a continuation-based one. A Seaside application is built out of components (i.e., objects) and the logic of the application benefits from the continuation-based program flow infrastructure. Seaside offers a unique way to have multiple control flows on a page, one for each component. This enables the developer to write components that are highly reusable and that can be used to compose complex web applications with higher quality in less time."

  abstract: "Due to the size and the extreme complexity of legacy systems, it is nearly impossible to write from scratch tests before refactoring them. In addition object-oriented legacy systems present specific requirements to test them. Indeed late-binding allow subclasses to change fundamental aspects of the superclass code and in particular call flows. Moreover Object-oriented programming promotes a distribution of the responsibilities to multiple entities leading to complex scenario to be tested. In such a context one of the few trustable source of information is the execution of the application itself. Traditional forward engineering approaches such as unit testing do not really provide adequate solution to this problem. Therefore there is a need for a more expressive way of testing the execution of object-oriented applications. We propose to represent the trace of object-oriented applications as logic facts and express tests over the trace. This way complex sequences of message exchanges, sequence matching, or expression of negative information are expressed in compact form. We validated our approach by implementing TestLog a prototype tool and testing the Moose reengineering environment and a meta-interpreter."

  abstract: "Meta programming is the act of reasoning about a computational system. For example, a program in Prolog can reason about a program written in Smalltalk. Reflection is a more powerful form of meta programming where the same language is used to reason about, and act upon, itself in a causally connected way. Thus on the one hand we have meta programming that allows different languages or paradigms to be used, but without causal connection, while on the other hand we have reflection that offers causal connection but only for a single language. This paper combines both and presents inter-language reflection that allows one language to reason about and change in a causally connected way another language and vice versa. The fundamental aspects of inter-language reflection and the language symbiosis used therein, are discussed. Moreover the implementation of two symbiotic reflective languages is discussed: Agora/Java and SOUL/Smalltalk."

  abstract: "Inheritance is well-known and accepted as a mechanism for reuse in ob ject-oriented languages. Unfortunately, due to the coarse granularity of inheritance, it may be difficult to decompose an application into an optimal class hierarchy that maximizes software reuse. Existing schemes based on single inheritance, multiple inheritance, or mixins, all pose numerous problems for reuse. To overcome these problems we propose traits, pure units of reuse consisting only of methods. We develop a formal model of traits that establishes how traits can be composed, either to form other traits, or to form classes. We also outline an experimental validation in which we apply traits to refactor a non-trivial application into composable units."

  abstract: "Following last two years' workshop on dynamic languages at the ECOOP conference, the Dyla 2007 workshop was a successful and popular event. As its name implies, the workshop's focus was on dynamic languages and their applications. Topics and discussions at the workshop included macro expansion mechanisms, extension of the method lookup algorithm, language interpretation, reflexivity and languages for mobile ad hoc networks. The main goal of this workshop was to bring together different dynamic language communities and favouring cross communities interaction. Dyla 2007 was organised as a full day meeting, partly devoted to presentation of submitted position papers and partly devoted to tool demonstration. All accepted papers can be downloaded from the workshop's web site. In this report, we provide an overview of the presentations and a summary of discussions."

  abstract: "A class extension is a method that is defined in a module, but whose class is defined elsewhere. Class extensions offer a convenient way to incrementally modify existing classes when subclassing is inappropriate.  Unfortunately existing approaches suffer from various limitations. Either class extensions have a global impact, with possibly negative effects for unexpected clients, or they have a purely local impact, with negative results for collaborating clients. Furthermore, conflicting lass extensions are either disallowed, or resolved by linearization, with consequent negative effects. To solve these problems we present classboxes, a module system for object-oriented nguages that provides for method addition and replacement.  Moreover, the changes made by a classbox are only visible to that classbox (or classboxes that import it), a feature we call local ebinding. To validate the model we have implemented it in the Squeak Smalltalk environment, and performed benchmarks."

  abstract: "Recent years saw the development of a composition mechanism called Traits. Traits are pure units of behavior that can be composed to form classes or other traits. The trait composition mechanism is an alternative to multiple or mixin inheritance in which the composer has full control over the trait composition. To evaluate the expressiveness of traits, some hierarchies were refactored, showing code reuse. However, such large refactorings, while valuable, may not exhibit all possible composition problems, since the hierarchies were previously expressed using single inheritance and following certain patterns. This paper presents our work on designing and implementing a new trait-based stream library named Nile. It evaluates how far traits enable reuse, what problems can be encountered when building a library using traits from scratch and compares the traits solution to alternative composition mechanisms. Nile's core allows the definition of compact collection and file streaming libraries as well as the implementation of a backward-compatible new stream library. Nile method size shows a reduction of 40% compared to the Squeak equivalent. The possibility to reuse the same set of traits to implement two distinct libraries is a concrete illustration of trait reuse capability."

  abstract: "Wikis are often implemented using string-based approaches to parse and generate their pages. While such approaches work well for simple wikis, they hamper the customization and adaptability of wikis to the variety of end-users when more sophisticated needs are required (i.e., different output formats, user-interfaces, wiki managment, security policies, ...). In this paper we present SmallWiki, the second version of a fully object-oriented implementation of a wiki. SmallWiki is implemented with objects from the top to the bottom and it can be customized easily to accommodate new needs. In addition, SmallWiki is based on a powerful meta-description called Magritte that allows one to create user-interface elements declaratively."

  abstract: "Grammars for programming languages are traditionally specified statically. They are hard to compose and reuse due to ambiguities that inevitably arise. PetitParser combines ideas from scannerless parsing, parser combinators, parsing expression grammars and packrat parsers to model grammars and parsers as objects that can be reconfigured dynamically. Through examples and benchmarks we demonstrate that dynamic grammars are not only flexible but highly practical."

  abstract: "Nowadays, many complex applications are built with a                   web browser as their main user interface. However,                   despite the increasing popularity of the web as an                   application platform, implementing and maintaining                   web applications still remains difficult and lags                   behind conventional desktop application development.                   The underlying technologies such as HTTP for the                   interaction and XHTML/CSS for the presentation were                   originally built to display and link static                   documents.  Unfortunately, most mainstream                   frameworks provide only little abstraction over the                   page-oriented structure imposed by those                   technologies. Inevitably, the goto-like manner of                   how pages are linked leads to spaghetti code and                   hampers reuse. In this article we present Seaside, a                   web application framework that provides an uniform                   and pure object-oriented view on web                   applications. In this way, Seaside avoids the                   unwieldily goto-like style. Exploiting the                   reflective features of Smalltalk, Seaside                   reintroduces procedure call abstraction in the                   client-server context. Seaside's key concepts are:                   (i) a component architecture supporting multiple,                   simultaneously active control flows, (ii) a                   programmatic XHTML generation, and (iii) fully                   supported on-the-fly debugging, code-editing, and                   recompilation. In this article we discuss these key                   features of Seaside and explain how they are made                   possible by the dynamic nature and the reflective                   capabilities of Smalltalk."

  abstract: "Seaside is the open source framework of choice for developing sophisticated and dynamic web applications. Seaside uses the power of objects to master the web. With Seaside web applications is as simple as building desktop applications. Seaside lets you build highly dynamic and interactive web applications. Seaside supports agile development through interactive debugging and unit testing. Seaside is based on Smalltalk, a proven and robust language implemented by different vendors. Seaside is now available for all the major Smalltalk including Pharo, Squeak, GNU Smalltalk, Cincom Smalltalk, GemStone Smalltalk, and VA Smalltalk."

  abstract: "In pure object-oriented languages, classes are objects, instances of other classes called metaclasses. In the same way as classes define the properties of their instances, metaclasses define the properties of classes. It is therefore very natural to wish to reuse class properties, utilizing them amongst several classes. However this introduced metaclass composition problems, i.e., code fragments applied to one class may break when used on another class due to the inheritance relationship between their respective metaclasses. Numerous approaches have tried to solve metaclass composition problems, but they always resort to an ad-hoc manner of handling conflicting properties, alienating the meta-programmer. We propose a uniform approach that represents class properties as traits, groups of methods that act as a unit of reuse from which classes are composed. Like all the other classes in the system, metaclasses are composed out of traits. This solution supports the reuse of class properties, and their safe and automatic composition based on explicit conflict resolution. The paper discusses traits and our solution, shows concrete examples implemented in the Smalltalk environment Squeak, and compares our approach with existing models for composing class properties."

  abstract: "Meta-programming is the act of using one system or language to reason about another one. Reflection describes systems that have access to and change a causally connected representation of themselves, hence leading to self-extensible systems . Up to now, most of the reflective languages have been implemented in the same paradigm. In this paper, we propose \\emph{symbiotic reflection} as a way to integrate a meta programming language with the object-oriented language it reasons about and is implemented in. New to this approach is that any element of the implementation language can be reasoned about and acted upon (not only the self representation), and that both languages are of different paradigms. Moreover, every language implementer that is faced with the problem of allowing the base language to access the underlying meta-language has to solve the problem of enabling entity transfer between both worlds. We propose a uniform schema, called upping/downing, to this problem that avoid explicit wrapping or typechecking. We illustrate this with SOUL (the Smalltalk Open Unification Language), a logic programming language in symbiotic reflection with the object-oriented language Smalltalk. We show how SOUL does logic reasoning directly on Smalltalk objects, and how to use this to implement type snooping"

  abstract: "Wikis are often implemented using string-based                   approaches to parse and generate their pages. While                   such approaches work well for simple wikis, they                   hamper the customization and adaptability of wikis                   to the variety of end-users when more sophisticated                   needs are required (i.e., different output formats,                   user-interfaces, wiki managment, security policies,                   ...). In this paper we present SmallWiki, the second                   version of a fully object-oriented implementation of                   a wiki. SmallWiki is implemented with objects from                   the top to the bottom and it can be customized                   easily to accommodate new needs. In addition,                   SmallWiki is based on a powerful meta-description                   called Magritte that allows one to create                   user-interface elements declaratively."

  abstract: "Developing applications that end users can customize                   is a challenge, since end users are domain experts                   but still have concrete requirements. In this master                   thesis we present how we used a meta-driven approach                   to support the end user customization of Web                   applications. We present Magritte, a recursive                   meta-data meta-model integrated into the Smalltalk                   reflective meta-model. The adaptive model of                   Magritte enables to not only describe existing                   classes but also let end users build their own                   meta-models on the fly. Further on we describe how                   meta-interpreters automatically build views,                   reports, validating editors and persistency                   mechanisms.  As a complete example of how we applied                   a meta-model to a Web application we present Pier,                   the second version of a fully object-oriented                   implementation of a content management system and                   Wiki engine. Pier is implemented with objects from                   the top to the bottom and is designed to be                   customizable to accommodate new needs. The                   integration of a powerful meta-description layer                   makes it a breeze to extend the running system with                   new functionality without having to patch the core                   engine.  We describe the lessons learned from using                   the Magritte meta-model to build applications. Both                   projects described in this thesis are open source                   and can be downloaded from the Web site of the                   author."

  abstract: "Lint-like program checkers are popular tools that ensure code quality by verifying compliance with best practices for a particular programming language. The proliferation of internal domain-specific languages and models, however, poses new challenges for such tools. Traditional program checkers produce many false positives and fail to accurately check constraints, best practices, common errors, possible optimizations and portability issues particular to domain-specific languages. We advocate the use of dedicated rules to check domain-specific practices. We demonstrate the implementation of domain-specific rules, the automatic fixing of violations, and their application to two case-studies: (1) Seaside defines several internal DSLs through a creative use of the syntax of the host language; and (2) Magritte adds meta-descriptions to existing code by means of special methods. Our empirical validation demonstrates that domain-specific program checking significantly improves code quality when compared with general purpose program checking."
