The Future of Xtext

Sven Efftinge , Sebastian Zarnekow

Xtext has been around for a couple of years now, proving itself as a solid basis for language development in large and small scale projects. It is used in commercial products in all kinds of vertical industries and has been a basis for many research projects.
In this session we discuss where the framework is heading and how existing users will benefit from future development.

ESON - The EMF Simple Object Notation

Michael Vorburger

The session presents ESON, the EMF Simple Object Notation, which looks, sings, dances and smells (almost) like JSON, but retains EMF's strong typing, and is in effect an alternative to the XMI XML syntax for EMF. ESON is internally implemented with Xtext, but is "dynamic" and can be used as new serialization format by any EMF users having a standard ecore (or Xcore) model - WITHOUT requiring a dedicated Xtext grammar. ESON was presented at EclipseCon EU 2013 (at the Modeling Symposium) and at EclipseCon NA 2014 (full talk), and has meanwhile become a formal sub-project of EMF on eclipse.org. This talk is an opportunity to revisit where it's at since.

Oomph: Eclipse the Way You Want It

Ed Merks , Eike Stepper

Each time you set up a fresh development environment for a particular project you go through a vast number of tedious tasks: You must install an IDE with appropriate plugins, check out a specific branch of a repository, import the appropriate projects in the workspace, define and materialize the appropriate target platform, apply the project’s team settings and preferences, install your personal tools, and manage your personal preferences. These tasks need to be well documented and evolve from release to release. No wonder new team members usually need a couple of days to get started.
Instead of writing this done in wikis or other informal documents, we should explain our machines how to do the job: let’s automate it. With Eclipse Oomph all these tasks are formalized. You will leave this session with a good understanding of how to author a fully automated script that always produces an Eclipse development environment exactly the way you want it.

Bring Your Language to IntelliJ IDEA

Anton Kosyakov , Stefan Oehme

Xtext goes multi platform! First stop: IntelliJ. Jetbrains' IDE is quickly becoming a favorite among developers, especially with Google basing its new Android Studio on it. This has resulted in many requests to get Xtend support on IntelliJ. But we didn't stop with Xtend. You can now generate an IntelliJ plugin for any Xtext language!
Best of all, you can reuse a lot of the code you already have, like scoping and validation. Other parts like the parser are generated for you. And of course everything is configurable. In this session you will learn how to create an IntelliJ plugin for your language and get an overview of the main differences to developing for Eclipse.

Introduction to Xbase

Holger Schill

Xtext makes it easy to define domain specific languages, but making your DSL a first class programming artifact with support for expressions and integration with Java is a hard thing if you do it from scratch. The Xbase library is an integral part of the Xtext framework. Xbase implements the bridge from DSLs to Java. It greatly simplifies your language implementation, if you want to run your DSL on the JVM. Xbase consists of a very powerful Java-like expression grammar and implements all the necessary infrastructure to link your DSL against existing Java types, compile it to executable code and validate it against the JVM specific constraints. In this session I want to explain how Xbase works under the covers and dive into its APIs. You will see, how to enhance your language and make it highly expressive and powerful without introducing an artificial gap to the Java platform. If you want your DSL to be a first class programming artifact, come to this session and see how to benefit best from Xbase.

Model based migration of legacy software

Arjan Mooij

Industrial software must continuously be maintained. This is caused by external constraints (such as the obsolescence of technologies like Windows XP) and by internal technology changes. After several years of maintenance, a software redesign is needed to support further innovation. This is often postponed, because it is time consuming and it does not immediately create new product features.
The challenge is to obtain a cost effective solution for software migration in an industrial context.Starting from scratch using a green field approach is not feasible; the domain knowledge must be maintained. As documentation is usually out-dated, the legacy software itself becomes the primary information source. This information can be revealed by analysing the source code and by learning from the observable behaviour.
In this talk we present our experiences with the field service procedures for the interventional X-ray machines of Philips HealthCare. The legacy software has evolved over many years into a large code base that is difficult and costly to maintain and extend. Model-based migration extracts models from the legacy software, and transforms these models to a new model-based design. In comparison to manual migration, we estimate that model-based migration gives an 80% effort reduction.

Extending the Xbase Type System

Sebastian Zarnekow

The Xbase type system implements the type computation for all Xbase library expressions. It resolves overloaded methods with the same semantics as in Java, implements the array to list conversion, boxing or unboxing logic and the assignability for lambda expressions. On top of that, it is integrated with the scoping and validation rules of Xbase languages. Given the central role that the type system plays, it is worthwhile to look under the covers. How do you customize the type system and which knobs have to be turned to add new expressions to your language? How do you introduce own library types with global extension functions? What's the best hook to tweak the assignability according to your needs? And what's the deal with all these type references. In this session you'll get a deep dive and learn the gory details about the Xbase type system. No PhD in type theory required.

Enhancing Graphical Editors with Xtext

Miro Spönemann

There are two aspects of graphical editing to which Xtext can add significant value: the persistence format and the editing of object details, which is usually done through the Properties view. In this session we will walk through examples realizing the integration of Xtext with GMF, Graphiti, and Sirius. For such an integration to work reliably, we have to be careful how to design the graphical and the textual concrete syntax and the mapping to model elements (abstract syntax). We also have to learn about the serialization infrastructure of Xtext and the synchronization concepts of the different frameworks, equipping you with a sound overview for enhancing your own graphical editors.

Lightweight Xtext Editors as SWT Widgets

Moritz Eysholdt

You probably know the Xtext editor as the smart text editor that is registered for certain file extensions in your Eclipse Workbench. But there are more use cases where an Xtext editor comes in handy: Inside wizards, previews, preferences dialogs, property views, graphical editors, form-based editors, you name it. This all becomes feasible by using the Embedded Xtext Editor, which is in fact an SWT widget. In this talk I will demo how to integrate the Embedded Xtext Editor into an RCP application and I will explain possibilities and important considerations.

Sustainable Service Design through Xtext

Dr. Michael Bischoff

This talk introduces the Bonaparte DSL collection and serialization library and describes how they have been used in the Omni Channel Order Management system “aroma” at arvato Systems. An order management system has to interface with a variety of external systems, such as web shops, logistic systems, finance systems etc. An ESB can help to convert between the variety of formats, but adds to the overall complexity of the system landscape and also is not desirable in scenarios where low latency is important, for example online price calculations. Using Xtext DSLs, it is possible to define APIs in a technology agnostic form. Examples are given how to connect with the Apache Camel, the vert.x event bus or the netty channel handlers.
The second part of the talk covers add on DSLs related to data persistence. Bonaparte provides code generators for JPA 2 entities as well as generators for compact serialization formats as required for off heap caching solutions such as Terracotta or Hazelcast.

Continuous Integration for Xtext languages

Stefan Oehme

Xtext languages should be built, tested and deployed continuously. It's the only way to quickly and reliably get new features and bug fixes into your user's hands . This session explains how Xtext languages can be built and published using Maven Tycho and how the languages can then be used by both Maven and Gradle clients.

EMF Parsley

Francesco Guidieri

In this talk we will present our project EMF-Parsley that is built on top of EMF. We like to consider our framework an Xtext-success-story because of several mechanisms that have been re-used as well as in Xtext. In fact EMF Parlsey provides some components like Tree, Table and Forms that can be easily customized thanks to the Dependency Injection. Moreover we used a polimorphic dispatcher to let the user customize parts depending of EMF types. Last but not least, we implemented a DSL to deeply customize all aspect of our framework, thanks to Xbase.
In this talk we will present how we did it and the lastest new features.

15:40 - 16:10

Integrating DSLs in Web Applications

Miro Spönemann

A major benefit of domain-specific languages is to create abstractions over the technical details of platforms or programming languages. This abstraction is particularly important for domain experts with no programming experience. However, installing and maintaining an Eclipse-based client application providing an IDE for your DSLs might not always be feasible. From the perspective of such users, accessing the required features in a web browser would be much easier and faster. In this session I will present the current roadmap for the wedding of Xtext and the web, focusing on what we have achieved so far as well as what you can expect for the near future. The session is accompanied by a demonstration of XRobots: a browser game that uses an Xtext DSL to control Lego Mindstorms robots for sumo fighting.

Testing with Xpect

Moritz Eysholdt

Xtext comes with Junit4 support out of the box, which is great for unit testing. Xpect on the other hand allows to define test expectations right within your DSL inside comments. As a result everyone who understands your DSL can write and read the tests. This is especially beneficial when working with more domain-related people, such as a Quality Assurance (QA) department.

Xtext editors in JavaFX

Tom Schindl

JavaFX 8 is a modern UI-Framework allowing to construct slick UI applications and Xtext is a powerful cross-platform DSL-Framework allowing people to define editors in a very simply way.
So far Xtext editors have only been available for SWT (Eclipse), however the latest developments allow to use more and more of the editor services in other environments as well. In this talks I will demonstrate how you can add support for Xtext languages to your JavaFX applications with a similar feature set than the ones you know from Eclipse/IntelliJ.

Making Xbase look like Java

Lorenzo Bettini

In one of our Xbase DSL we needed the expressions to be Java expressions; such language is a reduced Java without OOP features, aiming at teaching programming to students, so that they get familiar with Java, Eclipse IDE and its features, without the burden of dealing with OOP features. We will show how we customized Xbase grammar rules to parse Java expressions, while reusing the whole Xbase infrastructure. We also show how to customize Xbase model, type system and code generator accordingly. In particular, we will detail the problems we had to face. Such customizations are not coupled with our DSL, and we believe they could be reusable. The language will be open-sourced soon.

17:00 - 17:30

Getting Rid of Backtracking

Dr. Jan Köhnlein

The more your language grows, the more likely you will encounter syntactic ambiguities. Enabling backtracking eliminates the warnings of Antlr, but it will neither remove the cause nor perform acceptably. In the session you will learn why ambiguities arise, how to track them down and finally how to eliminate them efficiently.

Using Xcore models with Xtext

Holger Schill

Xcore is a textual format to define ecore models. This not only makes editing and reading much more convenient but has other cool advantages as well. Xcore, for instance, allows to embed Xbase expressions to define logic within EOperations and the like.
In this session you will learn, why and when using Xcore is a good idea and how to use it with Xtext languages. I will explain talk about which URIs to use, and how to properly configure the MWE2 file as well as more complicated setups, with multiple languages and mixtures of ecore, xcore and generated models.

Lightweight Diagrams for your DSLs

Christian Schneider

Textual notations have proven extremely helpful. On the other hand, mistakes can be hidden very well in chunks of keywords and characters. The Kieler Lightweight Diagrams (KlighD) toolkit assists you in creating visual representations of your data. Simply tell KLighD how to visualize the data by implementing a translation into a uniform and self-contained view model. The toolkit offers automatic layout, collapsing, expanding, and scaling of single diagram elements, diagram clipping, cropping, zooming, and more. I'll demonstrate the usage of KLighD combined with Xtext, implementing a diagram synthesis using an internal DSL on top of Xtend, and introducing interactivity via click actions.

From Spaghetti to Xsemantics - Practical experiences migrating typesystems

Andreas Heiduk , Steffen Skatulla

Handwritten typesystems are quite easy in the beginning. Since the DSLs themself tend to grow and gather more complexity the typesystem gets unmainaintable quite soon. In our case there are 12 interconnected DSLs used by several development teams and a huge existing model...
We will talk about our experience migrating from a "historically grown" typesystem to a clean, rule bases typsystem using Xsemantics. First we share our experiences with the language and tooling of Xsemantics. Then we describe how to create a common typesystem for multible languages efficiently and round up with tips & tricks for smooth migration of existing models.

Life of an Xtext Resource

Sven Efftinge

In this talk I will walk through the different life cycles of an Xtext resource. You will learn about the different phases and what their responsibilities and contracts are. The differences between how things work in the builder, an editor and a standalone build will be discussed as well.

EAI and Xtext DSLs

André Lehner , Dietmar Stoll

To improve the integration of their heterogeneous applications that run on different platforms and use various communication protocols, the Zurich Cantonal Bank (ZKB) renewed their integration platform. Domain specific languages (DSL) are used to describe integration artifacts. From these descriptions, business objects, connectors and documentation are generated. The presentation highlights results and lessons learned from the effort. In addition, it gives an outlook to a new project which involves describing batch jobs and their dependencies using DSLs and a model-driven approach to migrate legacy batch jobs from mainframe code.

The New Formatter API

Moritz Eysholdt

Good code is nicely formatted. But doing formatting by hand is tedious and formatting styles should not vary across team members. Luckily formatting is easy to automate.
In version 2.8, Xtext introduces a new and far more powerful API to implement formatters. A primary objective is to support domain-specific formatting, e.g. align tokens in columns or even arrange text in tables. Another use case is pattern-aware formatting. In contrast to the old API, it is possible to make formatting decisions based on the AST and format the tokens of terminal- and datatype-rules. In this talk, I will give an introduction to the new API and explain use cases based on examples.

Scaling Xtext

Lieven Lemiengre , Hendrik Eeekhaut

Using Xtext for the first time is usually a very positive experience. Although Xtext is a complex generic framework, it is very easy to create your first Xtext-based editor, because of Xtext’s smart defaults and intuitive APIs. Even with minimal initial effort, the results are quite spectacular. Unfortunately the initial excitement often turns into disillusion as soon as you use your plugin on a big project.
Many development teams hit a performance wall as their plugin gets deployed and has to support larger projects. Internally, Xtext is a complex beast. The internals are carefully hidden from the user, but understanding them is critical to understand where the performance bottlenecks come from.
At Sigasi we have built commercial tool support for complex hardware description languages (VHDL, Verilog, SystemVerilog) using the Xtext framework. Our plugin needs to handle big industrial sized projects (>400k lines of code) that include large generated files (2 to 10 MB). To handle these kinds of projects we have developed a set of techniques over the last four years.
In this talk we will cover some performance critical pieces of the Xtext framework and evaluate what can be done to optimize it (think: parallel loading, caching, fast linking,…). We will also discuss some workarounds that can be used if nothing else works (light-weight editors, reducing the workload of the compiler).

Improving the Responsiveness of Your Xtext-based IDE

Dr. Jan Köhnlein

Only a fast IDE is a good IDE. Users expect immediate feedback on their actions, and they hate to be blocked by processes like the auto-build. In this session we will uncover the performance improvements we implemented in the recent releases and give you hints what you can do to keep your Xtext IDE live and responsive.

DeltaJ - Enhancing Software Product Line Development

Sven Schuster

Although Software Product Lines (SPL) gain momentum, developing SPLs efficiently is still quite a challenge. Consequently, modular programming techniques, such as Delta-Oriented Programming (DOP) following a transformational approach, emerged in recent years. In such modular languages, especially scoping and type checking are difficult to realize. In this session, we present DeltaJ, a delta-oriented Java 5 dialect developed using Xtext. We describe how we tackled the issue of scoping a modular language in the current (bleeding-edge) prototype and propose a way of implementing a type system for DeltaJ with Xtext.

Scoping Tips and Tricks

Sebastian Zarnekow

The scoping implementation is often considered to be one of the most complicated parts of a language implementation. Though in fact it can be seen as a few concepts that have to be combined orthogonally, it is often not obvious how the existing abstractions can be used most efficiently. The scoping tips and tricks include guidelines how to best leverage the API and gain most from the default implementations. You will learn how to drive the validation directly from the scoping implementation, detect unused elements on the fly or how to provide aliases for elements from the scope. You will also see which bogus patterns should be avoided, why scope filtering is error prone and how content assist uses the scoping to create proposals. If you ever got stuck in your scoping logic, this is the right session for you.

Lightweight Code Generation with Active Annotations

Stefan Oehme

Code generation has a long tradition in Java-land. Modeling languages and code generators have advanced in recent years and have become a very helpful tool to get rid of structural boilerplate. On the downside, using modeling languages, you typically leave the fancy Java IDE behind and cannot mix and match your modeling language with real code. Additionally the turn around times when evolving a domain specific language and a corresponding code generator are often not good and the distribution of the plug-ins for a modeling language add a significant burden to the project.
For developer centric code generation, Xtend's active annotations are a much more lightweight and simpler approach. It lets you implement code generators and DSLs as a library, so you can easily enhance and distribute your code generation solution. No need to install a new plug-in everytime you have changed your DSL or the generator. And the best is, that the Eclipse IDE is fully aware of your DSL and will adapt the changes as you type.
In this session you will learn about active annotations in Xtend and how to apply them in any standard Java project.

Graphical Views for Xtext with FXDiagram

Dr. Jan Köhnlein

FXDiagram is a framework for diagram tools based on JavaFX. It puts a strong focus on user experience and offers an easy-to-use high-level API for Xtext-based languages. In this session you will learn how to integrate diagram views to visualize and explore Xtext-based models in your IDE. These views are highly customizable, have a modern look & feel and are actually fun to use.

Headless Compiler with Xtext

Torsten Krämer

How to develop a headless compiler for a non-trivial Xtext-based language, which is independent of core eclipse-workspace centric file handling and data management? Considering automation many projects face the need to integrate language-artefact processing into automated server-side or script-based workflows. Such scenarios often lack the availability of a workspace or actively try to avoid it. This has a major impact on the way the language is processed. Thinking of libraries, projects, modules, imports and exports, runtime-provision and runtime-dependencies many challenges arise in processing interdependent artefacts. The way towards a single runnable jar as the entry-point for compiling such projects - either file by file or in one go - are outlined and presented based on a real world project.

How to build a Python IDE with Xtext

Sebastian Zarnekow

Indentation based languages are quite popular in the language community. After all, semantic whitespace is an implicit means to get rid of formatting flame wars. The idiomatic formatting is implicit due the meaning of spaces and tabs. Even though it was possible to implement that with Xtext for quite some time, with Xtext 2.8, it finally became feasible without digging into the glory details of Antlr lexing and parsing. Just apply a few tweaks to the grammar and the language configuration, and you are good to go. You want to create a pythonesque language with Xtext? Come to this session and learn how to get rid of curly braces!

Model based migration of a large oracle forms application

Karsten Thoms , Max Vollmer

As part of the corporate's IT strategy, RHENUS Logistics decided to migrate Oracle Forms applications towards Java based approaches and fade out Oracle Forms from the technology stack. The main application consists of 16 subsystems and over 1200 forms. After the evalution of different products and approaches, RHENUS decided to build an Eclipse based tool chain to support the migration towards a DSL based development environment. With means of code generation, Oracle Forms metadata is transformed to the newly defined DSL languages. A second code generator translates the DSL models into a fully working application skeleton. While a great amount of the existing forms can nearly completely be translated, some manual implementation effort remains for forms with complex PL/SQL based business logic. After the initial migration of the Oracle Forms modules, RHENUS developers will use the new tool chain to develop the application further in the future. After successful migration of TMS, the tools will be used to migrate other remaining Forms based application.
The complete tool chain is based on Eclipse technologies, with Xtext, Xtend, EMF playing a major role. The application's target architecture is based on Eclipse Scout for the (Web-/RAP-based) client and service layer, and EclipseLink for the integration with the Oracle database.
We will discuss in this talk the migration approach against other approaches the customer considered in their evaluation. Further we will share our experience in using the Scout framework in this large user scenario and how the application developers, which have a strong Oracle but little to no Java background at all, perceived the new development environment.
