I've been reading Meyer's book on Object Oriented Software Construction, and I see a lot of things about Eiffel that look appealing. In particular, assertions, multiple inheritance, and the extensive library functions caught my eye. Also the regular way Eiffel deals with all 'features' of objects. Has anybody had any real-life experience with Eiffel, and does anyone know the details of the 'Research and Teaching' license for CS Departments? -- ----------------------------------------------------------------- | Vince Heuring Dep't of Electrical & Computer Engineering | | University of Colorado - Boulder heuring@colorado.EDU | -----------------------------------------------------------------

I started working with Eiffel and feel quite confident with the language. What I was wondering is what applications have already been written by others. How well/fast/robust are these applications running? Have you been able to use the graphic library in a reasonable way? Any practical information concerning Eiffel and graphics would be most welcomed (I have had my own share of theory!). I, myself, want to write a graphical editor with Eiffel.

I have found, through my use of the software and my phone calls to ISE, that: 1) The documentation does not reflect the state of the software. Some documented classes/routines do not work (ISE admitted this to me) and some routines are present in the software and are not documented. 2) Event handling is slow. I found it best to mask out mouse motion completely or the application gets bogged down. 3) ISE misrepresented their product to me when the failed to tell me, when I purchased the software, that Eiffel 2.1 does not work well with any color monitor. The literature I received made no mention of this fact. I was told by technical support that ISE had no color monitors when they developed 2.1, so they just ignored them. I am not very happy with ISE's support of Eiffel right now. I've been hearing since July 24 that 2.2 will ship "at the end of the week". I did get them to send me a tape, but my machine could not read it, so I had to send it back. Has anyone out there received the upgrade to version 2.2? I'm anxiously awaiting 2.2 since I'm sure all the problems I've encountered so far have been fixed in the new release. :-) Steve Belle belle@skipper.dfrf.nasa.gov
