In this blog post I’ll describe my experience in preparing an Oomph setup for a non-trivial Xtext project, Xsemantics. This setup was kind of challenging because of the following features of my project, but I guess most of them can be found in any Xtext project: generated sources are not stored in the Git repository […]
The problem I was having when running SWTBot tests in Travis CI was that I could not use the new container-based infrastructure of Travis, which allows to cache things like the local maven repository. This was not possible since to run SWTBot tests you need a Window Manager (in Linux, you can use metacity), and […]
I’ve just started using the brand new Eclipse installer, and I’d like to report my experiences here. First of all, a big praise to Ed Merks and Eike Stepper for creating Oomph, on which the installer is based. 🙂 First of all, the installer is currently available in the “Developer Builds” section: Once you downloaded […]
This is the follow up of my previous post about building a custom Eclipse distribution. In this post I’ll show how to deploy the p2 site and the zipped products on Sourceforge. Concerning the p2 site, I’ll use the same technique, with some modifications, for building a composite update site and deploy it with rsync […]
In this tutorial I’ll show how to build a custom Eclipse distribution with Maven/Tycho. We will create an Eclipse distribution including our own features/plugins and standard Eclipse features, trying to keep the size of the final distribution small. The code of the example can be found at:Â https://github.com/LorenzoBettini/customeclipse-example First of all, we want to mimic the […]
This can be seen as a follow-up post of my previous post on building Eclipse p2 composite repositories. In this blog post I’ll show an automatic way for publishing an Eclipse p2 (composite) repository (a.k.a. update site) on Sourceforge, using rsync for synchronization. You may find online many posts about publishing update sites on Github pages […]
I like to build p2 composite repositories for all my Eclipse projects, to keep all the versions available for consumption. Quoting from https://wiki.eclipse.org/Equinox/p2/Composite_Repositories_(new) The goal of composite repositories is to make this task easier by allowing you to have a parent repository which refers to multiple children. Users are then able to reference the parent repository […]
I recently started to play with Sonarqube to reduce “technical debt” and hopefully improve code quality (see my previous post). I’d like to report on my experiences about using Sonarqube to analyze Xtend code. Xtend compiles into Java source code, so it looks like it is trivial to analyze it with Sonarqube; of course, Sonarqube will analyze […]
I recently started to play with Sonarqube to reduce “technical debt” and hopefully improve code quality. I’d like to report on my experiences about using Sonarqube to analyze Xsemantics, a DSL for writing rule systems (e.g., type systems) for Xtext languages. I was already using the Jenkins Continuous Integration server, and while building I was […]
This is a followup of my previous post, Switching from an inferred Ecore model to an imported one in your Xtext grammar. The rationale for switching to manually maintained metamodel can be found in the previous post. In this post, instead of using an Ecore file, we will use Xcore, Xcore is an extended concrete syntax […]
When you use Xtext for developing your language the Ecore model for the AST is automatically derived/inferred from the grammar. If your DSL is simple, this automatic meta-model inference is usually enough. However, there might be cases where you need more control on the meta-model and in such cases you will want to switch from an inferred Ecore […]
Revision History 18 April 2014 Modified the SWTBot test so that it can be reused also in a test suite (see the comments to this post). I happened to give a lecture at the University of Florence on Test Driven Development; besides the standard Junit tests I wanted to show the students also some functional […]
Up to now, I was always putting the Xtend generated Java files in my git repositories (for my Xtext projects), since I still hadn’t succeeded in invoking the Xtend standalone compiler in a Buckminster build. Dennis HĂĽbner published a post with some hints on how to achieve that, but that never worked for me (and apparently it […]
My book on Xtext, “Implementing Domain-Specific Languages with Xtext and Xtend” is now available on Packt website! Get it while it’s hot! 🙂 You can find the outline and an example chapter at http://www.packtpub.com/implementing-domain-specific-languages-with-xtext-and-xtend/book Many thanks to the reviewers of the book: Jan Koehnlein, Henrik Lindberg, Pedro J. Molina, and Sebastian Zarnekow! The sources of the examples presented […]
I’m happy to announce that my book “Implementing Domain-Specific Languages with Xtext and Xtend” is now available for pre-order on Packt website! 🙂 http://www.packtpub.com/implementing-domain-specific-languages-with-xtext-and-xtend/book
I know that Xtext 2.4 has not been released yet, but I could not resist blogging about a very cool new feature in Xbase: improved automatic import functionalities! Actually, import functionalities were already great when using Xbase also in previous versions of Xtext, but now they provide a much better experience for the user of […]
Revision History 9 May 2013 Updated listings to reflect the git repository sources. Put a tip on using a mirror aggregated with b3. In this tutorial I’ll show how to use Buckminster to build an Eclipse RCP Product, both in the IDE and headlessly (with ant). The application I’m building is the standard Eclipse Mail […]
In a previous post, I blogged about mirroring Eclipse repositories with the p2.mirror Ant task; Since this Ant task needs to be run via the Eclipse antRunner application, you need a full installation of Eclipse on the machine that will run the task and I showed how to run this task from the command line. […]
I used to have many Eclipse installations in my machines; typically they were different Juno versions downloaded from ecipse.org, for instance, Eclipse for RCP developers, Eclipse for DSL developers, Eclipse Modeling Tools, etc. Moreover, most of them were customized with the same plugins (for instance, Mylyn connectors) which I had to install on all of […]
Inspired by this nice blog post, I decided it was time to try to mirror some Eclipse repositories to speed up my builds that depend on target platforms insulate myself from outside servers be able to build also without an Internet connection reduce network traffic 🙂 To do this I’m using p2 ant tasks for […]
