KDE—The Next Generation
Now let's go back to some more basic components. The KDE configuration files have always been pure text files. This had the advantage that nothing could go corrupt—you could, if necessary, edit the text files by hand or use a Perl script to change the configuration files of a few hundred users at once. So, text-based configuration files are desirable. However, a typical KDE desktop has hundreds of these files not only for each application, but also for each MIME type, each service type and so on. This led to slow application startup, because all these files had to be opened and parsed. The solution to this is KSycoca, the KDE system configuration cache. KSycoca is a sort of daemon running in the background and watching for changes in the configuration files. KSycoca reads all configuration files and builds a binary database which can be accessed much faster than the individual, text-based files. However, those are still the authoritative source of all configuration information, so you can edit them by hand or by scripts. In case anything goes wrong with KSycoca, it can simply dump its database, because it is nothing more than a cache and contains no information unavailable elsewhere. Compare that to operating systems with binary registers which can get messed up so badly you cannot boot up your operating system!
We have already talked about some internal changes in KOffice. The development of new features is also progressing. Implementing import filters is a very hard task, but Werner Trobin has already made some progress, so there is hope that KWord (see Figure 4) will be able to import Word 97 documents in the not too distant future. KPresenter (see Figure 5) now supports presentation templates, and KSpread (see Figure 3) has also received many more features too numerous to list here—check it out yourself. However, there are (besides the “old” applications KSpread, KWord, KPresenter, KIllustrator, KChart and KFormula) two new kids on the block. KImageShop is a multi-threaded image-manipulation program that aims at being as powerful as the GIMP, but easier to use. Also, KImageShop has a very clean C++ design that will make extensions much easier. KImageShop will not be ready for public use any time soon, but shows some very promising results. Finally, kdatabase is a database front end that aims at making database power more accessible for the end user, and of course, features embedding into other KOffice applications.
KDevelop, the KDE Integrated Development Environment (IDE), is one of the sub-projects that is perhaps making the most progress. By the time you read this, version 1.0 should be out, and it features, among other new things, support for Objective-C and a very nice class tree view. KDevelop's development is a bit decoupled from KDE, i.e., it does not follow the same release plans. However, the KDevelop people put much effort into ensuring KDevelop always works with the current KDE versions.
Another important change comes from the documentation team. All the documentation is moving from the LinuxDoc SGML DTD to the more powerful and professional DocBook DTD that most professional publishers use. This move is also being executed by the LinuxDoc people, so that DocBook will become the pre-eminent standard for Linux documentation in the future.
All those changes, new features and new applications, impressive as they may seem, are simply nothing against the one true KDE killer application that has appeared recently: ky, the KDE implementation of the classic UNIX yes tool!
