Caveat

Flower was an interesting prototype, but I stopped working on it in 1995.

Flower CASE Tool

I have a working prototype of a Case tool that I'm calling "flower" for now. It's written in Eiffel, and used Tcl/Tk for the GUI layer. I'm developing it under Linux, but it should run under any platform that supports the ISE Eiffel environment and Tcl/Tk (Tcl version 7.4, and Tk version 4.0). As soon as Tck/Tk are available for Windows/NT, this tool should work there. It should port to TowerEiffel and SiG's compiler without much effort.

The prototype is still a little rough around the edges, but it can be used to edit diagrams, and it supports loading and saving them. It supports a subset of the symbols on a Rumbaugh class diagram (Class, Association, Aggretation, and Generalization). Here's some of what it doesn't support:

Many of the symbols needed for proper Rumbaugh class diagrams, like objects and attributed relationships.
Labels or roles on relationships.
Free text on diagrams.
Printing. It looks like Tk does most of the work for me, but I haven't implemented this yet.
Anything that's not on a Rumbaugh class diagram.
Deleting figures from a diagram.
Closing or deleting a diagram.

Also, the code could stand a bit of cleanup and refactoring, and I've made no effort whatsoever to make it fast. Like I said, it's a prototype! :-)

The source, and linux binaries from 1995 are available on github at https://github.com/zathras/flower. Here is a sample diagram.

I'm interested in feedback!

If you've taken a look at Flower, I'm like your feedback. I'd like to know:

How much interest there is in my making a complete, polished version.
Any comment (good or bad) you might have on the design of the tool.
Any comments on my Eiffel coding style. This is the first project I've done in Eiffel, so I'd like to know how I did :-)
