In this tutorial I’ll show how to use Jacoco with Maven/Tycho to create a code coverage report of multiple Eclipse plug-in projects. The code of the example is available here: https://github.com/LorenzoBettini/tycho-multiproject-jacoco-report-example. This is the structure of the projects: Each project’s code is tested in a specific .tests project. The code consists of simple Java classes doing […]
The second edition of the Xtext book, Implementing Domain-Specific Languages with Xtext and Xtend, was published at the end of August: https://www.packtpub.com/web-development/implementing-domain-specific-languages-xtext-and-xtend-second-edition. So… get it while it’s hot 🙂 Please, see my previous post for details about the novelties in this edition. Sources of the examples are on github: https://github.com/LorenzoBettini/packtpub-xtext-book-2nd-examples. Hope you’ll enjoy the book!
The second edition of the Xtext book should be published soon! In the meantime it is already available for preorders. At the time of writing, you can benefit for discounts and preorder it at 10$. I’ll detail the differences and novelties of this second edition. But, first things first! A huge thank you to Jan Köhnlein, for reviewing […]
HiDPI support in KDE Plasma has been recently improved! I’m afraid what’s not improved is the procedure for using that. In this post I’ll detail the steps to use HiDPI with KDE if you have a high resolution display (for example, I have that in my Linux Dell M3800). Remember that the settings you change […]
In a previous post I showed how to manage an Eclipse composite p2 repository and how to publish an Eclipse p2 composite repository on Sourceforge. In this post I’ll show a similar procedure to publish an Eclipse p2 composite repository on Bintray. The procedure is part of the Maven/Tycho build so that it is fully […]
After I upgraded my Dell Precision m3800 to the new Kubuntu Wily 15.10 I had a very bad surprise: the screen was continuously flickering in a way that it was unusable. This happens only if you are NOT using the default highest resolution 3200×1800 which, at least for me, is really too small. I thought it was […]
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 […]
Hi I’d like to spread the world about the “Day Against DRM” campain from Packt Publishing: http://bit.ly/1EQrkF7 All ebooks and videos are 10$ You could take a chance to get my Xtext book “Implementing Domain-Specific Languages with Xtext and Xtend“. 🙂
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: 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 […]
I recently had to install Linux Kubuntu 13.10 Saucy Salamander (at the time of writing I’ve already upgraded it to 14.04 Trusty Tahr) on a Dell Precision M3800 (a really cool and powerful laptop, see the details here). The installation went really smooth, and I’m enjoying a very fast and stable Linux OS on this laptop. […]
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 […]
