Special thanks to all the twitterites who recommended UML modeling tools. Umbrello UML Modeler appears to be the one I was looking for. Here are a couple of quick notes about what I had to do to get it running on my Mac, mainly for my own future reference, but I hope these also help someone else.
First, make sure you have the Apple Xcode tools installed, along with X11.app.
$ sudo port install kde
The KDE installation can take quite a while, depending on your system. On my PowerBook G4, it took well over 7 hours. My Intel iMac was considerably shorter, but still took a couple of hours.
Once KDE is installed, you should have all the necessary libraries to build Umbrello. Download the Umbrello source and get to work:
$ wget http://prdownloads.sourceforge.net/uml/umbrello-1.5.8.tar.bz2?download $ tar jxf umbrello-1.5.8.tar.bz2 $ cd umbrello-1.5.8 $ ./configure --prefix=/opt/local --with-qt-includes=/opt/local/include/qt3/ \ > --with-qt-libraries=/opt/local/lib/qt3/ --with-extra-libs=/opt/local/lib \ > --with-extra-includes=/opt/local/include --without-arts $ make $ sudo make install
Umbrello is now ready to run. To run it, just open X11.app and enter the command:
That’s all there is to it!
Umbrello seems to be just the tool I needed. It appears to be a much more intuitive and easier-to-use UML modeling program than any others I have tried, and it will generate PHP 5 code. It doesn’t generate everything quite as well as I had hoped, but it gets the class stubs in place, and I can go back in and correct things for my coding standards and update the comment blocks as needed.
Also, another observation: applications built using the KDE libraries (i.e. Umbrello) do not appear to run as clunky on the Mac through X11 as those using GTK. They actually run quite smoothly.
