This post explains how to execute a single unit test (or even a single test method) instead of running the complete unit test suite. In order to run the unit tests of your rails application, basically you have these official possibilities: rake test: runs all unit, functional and integration tests. rake test:units: runs all the unit tests. rake test:functionals: runs all the functional tests. rake test:integration: runs all the integration tests.

I’m really pleased to announce that latest version of QJson on master is working on Symbian. You can find the installation instruction here. Since I’m not a Symbian developer it has been a little hard for me to achieve that. I would like to thank Antti Luoma for his help. There are also good news for Windows developers: now building QJson under Windows is easier. Checkout the new installation instruction page.

Just a quick note: I have just moved QJson source code to this git repository hosted by gitorious. I’ll keep the code on KDE’s svn synchronized with the git repository.

Some days ago I introduced the possibility to serialize a QObject instance to JSON. Today I’m going to show you the opposite operation: initializing a QObject using a JSON object. I refactored a bit my latest changes: I created a new class called QObjectHelper that provides the methods required to convert a QObject instance to a QVariantMap and vice-versa. This class can be used in conjunction with the Serializer and Parser classes to serialize and deserialize QObject instances to and from JSON.

I have just committed into trunk a couple of changes that make easier to serialize a QObject instance to JSON. This solution relies on the awesome Qt’s property system. Suppose the declaration of Person class looks like this: {% codeblock [class definition] [lang:cpp ] %} class Person : public QObject { Q_OBJECT Q_PROPERTY(QString name READ name WRITE setName) Q_PROPERTY(int phoneNumber READ phoneNumber WRITE setPhoneNumber) Q_PROPERTY(Gender gender READ gender WRITE setGender) Q_PROPERTY(QDate dob READ dob WRITE setDob) Q_ENUMS(Gender)

Some weeks have passed since the announcement of kaveau. I’m really proud and happy about this project because I received a lot of positive feedback messages and it has been chosen as one of the best Hackweek’s projects. In the meantime I kept working on kaveau, so let me show you what has changed: rdiff-backup has been replaced by rsync. the setup wizard has been improved according to the feedback messages I received.

Recently lots of people asked me how to build QJson under Windows. Most of them reported build/link errors, so I decided to try personally. The good news is that QJson can be successfully built under Window, I can show you proof ;) {% img /images/qjson/qjson_windows_1.png %} {% img /images/qjson/qjson_windows_2.png %} I have written the build instructions on QJson website: just take a look here. One last note: if you have problems with QJson please subscribe to the developer mailing list and post a message.

During the last week I had the possibility to work on anything I wanted, Novell’s hackweek is so cool :) I decided to dedicate myself to an idea that has been obsessing me since a long time. Last December my brand new hard disk suddenly died, making impossible to recover anything. Fortunately I had just synchronized the most important documents between my workstation and my laptop, so I didn’t lose anything important.

Gran Canaria Desktop Summit has been great and really productive. I had the pleasure to meet people interested in QJson, chat with them but also hack with them. In fact we hacked a lot, doing lots of changes to QJson: the API has been cleaned, now it can be considered stable unicode support has been completely rewritten it’s now possible to convert QVariant objects into JSON ones So it’s with a great pleasure that I announce the release of QJson 0.

Now that I have booked both the flights and the hotel it’s official: I’ll attend the Gran Canaria Desktop Summit. On Thursday 9th July I’ll give a BoF about QJson. During the talk I will show: the advantages brought by QJson. the usage of QJson. some real programs using QJson. See you soon!
