I’ve been waiting for that for months already. I’ve been whining and whining again about the lack of an internal SSH2 implementation in IntelliJ. And now, it is there! As you perhaps already know by reading my weblog, I’m a Groovy developper. And the Groovy project is hosted at Codehaus which makes use of SSH2 for accessing the CVS repository. I had tried, but without success, different alternatives, such as using Putty/pling/pageant, but I didn’t manage to create a connection. Read more...

Based on a suggestion made by Jamie McCrindle, I decided it was time to add some missing Groovy methods related to sockets. So far, I have added a bunch of IO/streams methods enhancing the JDK core classes, but there were no methods dealing with sockets. But now, this time is over. I have added two methods: Socket.withStreams(Closure) which takes a closure as argument, and has acces to an input stream and an output stream, and ServerSocket. Read more...

Unit tests aren’t really new for me, but so far, on the different projets on which I worked recently, I haven’t really had the opportunity to develop “test firt”. Moreover, I could not test much because those projects were not pretty test-friendly (static instances all around, nothing close to IoC/DI anywhere around). And also, on web-based and GUI projects, it is not that easy to write tests (when I have time, I should definitely have a look at those HTTP and Swing testing frameworks). Read more...

Over the week-end, I implemented new groovy methods, as defined in GROOVY-208 Plus a few complementary methods. getText(): BufferedReader.getText() File.getText() File.getText(encoding) Process.getText() You can now easily read the full content of a file or of a buffered reader and get it as a String. // retrieve the content of the file def content = new File("myFile.txt").text // you can specify the encoding of the file // note that since getText() has a parameter, // you cannot call it with something like text("UTF-8") content = new File("myFile.

When you want to make some optimizations to your code, you often use the good old System.currentTimeMillis() method to time certain parts of your application. I wanted to do a similar thing when hacking some Groovy scripts recently, and the idea came to me that I could simply create a timing closure! So here it is, for your eyes only: timer = { closure -> start = System.currentTimeMillis() closure() println System. Read more...

A year ago, Codehaus saw the light of day. And since, it gathered a lot of bright and talented persons working on innovative and very good quality projects. And moreover, those projects have a friendly licence scheme (I’m not a GPL/LGPL lover). For a few months, I’ve been part of the Hausmates, thanks to my efforts in developing some code for Groovy, and I’m really proud of beeing part of it. Read more...

Perhaps you noticed recently that there’s a new interesting page on Groovy’s website ? Well, all pages are interesting of course! But there’s a new page describing the Groovy methods enhancing the core JDK classes. In groovy, you have additional methods that you can call on standard Java classes. For instance, you can use the eachLine() method on java.io.File. With this method, you’ll be able to easily read a text file line after line, and do whatever with this line inside a closure without having to care about things like closing streams. Read more...

Yesterday, I was granted commit rights on the Groovy source tree, at Codehaus. Of special interest for me : I developed a utility class which helps Groovy create new Readers for text files with the correct encoding already set (I’m really keen on charset/encodings issues), Adding some new Groovy methods to the core JDK classes, Working on an automatic documentation generation engine “a la” Javadoc, so that it may be possible to browse all the methods that have been added to the core JDK classes.

That’s incredible, but Robert S. Sfeir is at it again in the EAP forum. He produced one more prayer that we should all be repeating again and again. (I hope he won’t mind me from quoting his holy words) Our IDEA who art in heaven Hollowed be thy name Thy IDE come, the EAP done On earth as it is in heaven, Give us this day our daily build, And forgive our bug reports, Read more...

After my suggestion of Miranda as a code name for the upcoming EAP of IntelliJ IDEA, there was a funny quote from Robert S. Sfeir in the forums regarding this suggestion. It’s a new version of the Miranda Rights : You have the right to refactor. Anything you refactor can be used against you in your code and calls. You have the right to have IDEA present now and during any future refactorings. Read more...
