I've looked around a bit on the free editors without finding anything I like so I'm thinking it might be worth trying a commercial editor. What do you guys use? Emacs :-) It takes a bit of work to get it set up nicely, but there are some really nice features like good pdb integration. e.g. try this: put a pdb.set_trace() somewhere in your code, and then run the program from a shell within emacs - e.g. you can start a shell by typing M-x shell, and then type the command to run your program. When you enter pdb, you can step around the code and emacs shows you where you are in another buffer, opening modules as you step into them. I've said it before: All hail Ken Manheimer! I'm sure plenty of IDEs can do stuff like that, but I'm surprised how many emacs users don't seem to know it's there. (dunno if all that works on Windows, never tried.) The code-completion support is pretty rudimentary, though. It seems to only be good for repeating symbols already in your source file.

Re: [Zope] Permissions, files and folders
Ok. I didn't find any epidoc on plone at a first googleing, but I have a closer look and post the link here if I find it. I solved some of the API doc problem by starting a local pydoc server (ex. pydoc -p 8079) which cover even the zope modules when I put them in the python path. But I'm still somewhat surprised that there is no more complete documentation on Zope. I will post my comments about this in a new thread since it no longer has anything to do with permissions and stuff. Anyway, thank you very much for your help Dieter.

[Zope] Permissions, files and folders
Hi!I just started looking at zope, so this might be a pretty nooby question, but I didnt find an answere anywhere, so...I want to create a DTML Method that lists the files in a folder that the current user has access to. Problem is that the objectValues-method returns all files simultaniously, so I get a
AccessControl.unauthorized.Unauthorized exception when I call the method. I did a litle python script that iterates over the objectValues and catches the errors raised from unauthorized files as folows:files = []
fileIterator = iter(container.objectValues('File'))while True: try: files.append(fileIterator.next()) except Exception, e: if isinstance(e,StopIteration): break
else: files.append(e)return files
This works
fine, except that it's a bit clumsy and has one big error; I catch just any
exception that arises from the files.append(fileIterator.next())-call, and swallow
it. I've tried catching only the Unauthorized-exception, but an anonymus user
does not have access to the Unauthorized-exception, so I can't specify is in my
except-declaration without getting a new authorization error. All thaw it works fine to catch all exceptions for a simple
directory listing like this, its defiantly nothing I wanna put into a larger application.
So my question
is, how do I do this in a nicer way?
Thanx /Erik
