Hi vincent
Now I'm working on the costume implementation of the IDocument Partitioner which uses the XDOM parser. But in order to to register partitions with the IDocument,requires the offset and the length of each token returned by the parser.
Did you get Marius' input on this?
I don't think I'll need the offset and length for any of the new WYSIWYG editor's features but if we're going to implement syntax highlighting in the wiki editor at some point, then they will be required for the same reason: determine what block is located at a specific location in the source document. So I guess Vincent's rendering component could provide you the offset and length, and you could compute the rest by yourself.
I remember I said:
" * Re the offset and lengthn I think this is something interesting that could be added to the new rendering module. Since the underlying parsers (wikimodel, doxia) don't pass this information to us we would need to compute it. It would allow us to answer the question "what block is located at location NN in the source document". * We need to get Marius' input since he's working on the new WYSIWYG editor for XWiki and maybe he has some similar needs/issues. "
The reason I said this is because if the only requirement is for your use case then you could easily compute the offset/lenght for your use case only (by writing a very simple Listener and running XDOM.traverse(yourllistener). However if the need is generic then it makes sense to have it in the rendering component itself.
I'm still hesitating about the generic need about this.
If we agree to add it in the rendering component then I can implement it for you.
Another question for you: once you have this information what's the algorithm for finding the block that corresponds to a given location in the source document? Dichotomy on the tree?
Thanks -Vincent
But the current implementation of the parser don't have that information.Do I need to look at that issuer as well or what? I have very little understanding of the implementation of the parser and I will be difficult for me to implement that functionality.
Vincent can you help me on this issuer.
