QxWT: Find out API changes between Qooxdoo-Releases

While trying to update my qooxdoo wrapper to 1.3. I had the problem that I could find out easily which classes, methods and properties have been added/remove between e.g. 1.2 and 1.3 so that I could adjust my GWT-Wrappers.

This was until Andreas Ecker from the qooxdoo team pointed me to an interesting Meta-Data information the generator spits out for the API-Viewer. It took me about an hour to write a small Java-Programm which created a diff of those .json-Files.

Below you see an example output of a diff between Qooxdoo 1.2 and 1.3.

You can download the small utility from here. The usage is quite simply as long as you have Java installed on your system.

Usage: java -jar qxapidiff.jar -v0 $APIVIEWER_DIR_VERSION_0 -v1 $APIVIEWER_DIR_VERSION_1 [-a 0|1|2]
	* -v0 (mandatory) ... Path to old versions API-Viewers script directory e.g. /home/tom/qx-1.0-sdk/framework/api/script
	* -v1 (mandatory) ... Path to new versions API-Viewers script directory e.g. /home/tom/qx-1.3-sdk/framework/api/script
	* -a ................ Minum-Access-Level for Method diff: 0 = private, 1 = protected, 2 = public
	* -h ................ Prints this message

if you think you can improve it, you are free to do so (e.g. to add constructors and method-arguments to the diff calculation) because you can access the sources from my public SVN-Repository.

I think in future I can use this informations to e.g. write create wrappers or at least their stubs automagically 🙂 but until then I need to wrap them by hand.

  1. Hi Tom,

    sweet! Great to see my input was helpful and you could create this handy tool out of it. Lets see were we could use that ourselves … 😉

  2. Hi Tom,

    Great work! Many GWT programmers need now a rich widgets library. QxWT may become a third (and I think, best) alternative to SmartGWT and GXT. Do you consider to continue develpment or it is in abandoned state now?

    • Tom Schindl says:

      No it’s been stalled a bit but we restarted updating it to the latest qooxdoo-release (the API svn head is already adjusted). I hope to find the time to release it soon (1-2 weeks)

      • That would be very nice especially because version 1.2 of Qooxdoo framework used in QxWT does not work properly in Firefox (4). And this limits a lot the usage of QxWT in cross-browser applications.
        Thank you.
