This is the same example I gave above.
This is a link to "a [[b" followed by the text "]]"

I agree, +1.
We can't have links inside links. It doesn't make sense since none
of
our renderers will support this. I also haven't seen any output
format
supporting this so far (even XPointer doesn't AFAIK). Mikhail (from
wikimodel) is also strongly against it.
What I have implemented is images inside links. So if you have the
following:
[[hello [[nolink]]>>reference]]
it will mean:
A link pointing to the following reference: "hello [[nolink"
followed
by the text: ">>reference]]". Is the first (end) "]]" marker
associated with the first or the last
(start) "[[" marker? In other words, is the parsing based on a queue
or
on a stack?
I would expect it to use a stack. In this case I'm not clear why the
inner block cannot be a child of the outer block in the resulting
DOM-like tree. The previous text can be invalid (doesn't pass a DTD-
like
check), but I think it should be well-formed (start markers pair with
end markers), provided we allow wiki syntax inside link label.
I may be missing something since I don't know much about what the
rendering module does under the hood.
This is not the rendering module. It's WikiModel which is using JavaCC
to parse the content.
What you suggested is possible but every complex and leads to 2 major
problems (this is what I started doing yesterday and ended up
reverting):
* If you don't have a closing ]] you have to go till the end of the
document and thus the rest of the document will be the reference...
* It's very slow (since you have to manually count the opening and
closing tokens till the end of the document)
Thanks
