I've almost finished my "translation" to Python of the examples in the ORBit Beginners Documentation (v1.6)[1]. The last one is the multi-threaded calculator and I am not too sure how useful it'll be to do (except for my learning :-) so I've left it for now.
I would very much like to have some feedback on it all, suggestions for improvement are especially welcome. Also someone sent me a private email offering some help. Unfortunately I lost the email (I have been known to do some aggressive cleaning of my inbox at times), I'd love it if you contacted me again. You can find the page here: http://magnus.therning.org/pyorbit_beg_exs.html These are some of the things I've been pondering, any answers/comments are welcome: 1. I had a practical problem with putting Python code on a web page (<> got lost) and I went looking for a py2html pretty printer that didn't create outrageous stuff (basically I want something rather low-key, and preferably not full html pages with body-tags and all but rather output that can be included. I found nothing and swapped to texinfo for the moment. Anyone with a solution to the problem? 2. (This relates to the NameResolve example) I couldn't get CORBA.ORB_init() to accept sys.argv (and hence I couldn't register a name-service with -ORBInitRef NameService=IOR:... on the command line. I probably made some trivial mistake. Any pointers? 3. (This relates to the Factory example) With interfaces like this: module M { interface IA { .. }; interface IB { IA createA(); }; }; and Python classes like this: class myIA(M__POA): ... class myIB(M__POA): ... then myIB.createA() can't be naively implemented like this: def createA(self): return myIA() but has to 1. create, and keep an instance of myIA alive 2. return that instance's _this() Why is it like this? (I guess it has its positive sides to not have the CORBA server-side representation of an object keep the instance alive, but I can't quite see them.) Anyone with an idea of how to kill the server-side Python instance immediately? (I currently simply remove it from the list (the list is the way I keep the objects alive in the first place) and garbage collection will get around to them, can I make sure it happens sooner?) Well, that's it for now. Looking forward to being flooded with responses ;) /M 1. http://www.gnome.org/projects/ORBit2/orbit-docs/orbit/index.html -- Magnus Therning (OpenPGP: 0xAB4DFBA4) [EMAIL PROTECTED] http://magnus.therning.org/ Time is an illusion.
