I think the opposite is true, Splitters and Volcabularies seem to be limited to
only being used by TextIndexes within PlugginIndexes.
I just put a bug in the collector about one aspect of this.
I think Vocabularies might be generically useful in Zope, not just to ZCatalog,
likewise splitters.
I'd love to be able to do:
context.mySplitter.split('the quíck brown f0x')
...for example.
But, it does seem exraordinarily hard to register new types of splitter.
Currently, the only way I can think to do it would be something like:
import MySplitter
from Products.PluginIndexes.TextIndex import Splitter
aS = Splitter.availableSplitters # why isn't availableSplitters a dictionary?!
aS = aS + ("MySplitter","My Special Funky Splitter")
Splitter.availableSplitters = aS
# worse still...
setattr(Splitter,'MySplitter',MySplitter)
...and I'm not even sure that'd work :(
Maybe Vocabularies should be in their own Product and maybe (although maybe not)
Splitters and Lexicons should be in their own Products too?
cheers,
Chris
