Spell Checker for Zope
by Robert Leftwich 09 Sep '99

09 Sep '99

I am looking for a spell checker that I can integrate with Zope to allow users to spell check their pages. After a fairly exhaustive and unfruitful search on the net I though I would see if anyone has any suggestions. Ideally it would be open source, support multiple languages, custom dictionaries and run on windows and linux (at least). The closest to this is Aspell, but it currently only has a C++ interface - might be time to play with SWIG to generate a python wrapper for it. TIA Robert Leftwich

I still have no idea about this one. I just thought I'd add that I am using Zope 2 and that my other trees behave fine, and that this one behaves fine except for Expand All.

So what would happen if this wrapper object was passed back using a <dtml-return> call or even a __bobo_traverse_ method? Would further resolution in the object happen using the link or would it break and start trying to find objects in the local context?
