Hi Tony,
yes I need the details, I already thought of the toc-macro...but I could
not figure out how limiting recursions is done there.
I think this is the more promising approach.
Thanks! Jan

Here is a quick high level answer, let me know if you want more details.
There are existing examples out there that avoid this like the
standard TOC however one method that comes to mind is as you iterate
each title add it to a variable "all members" (even a data tiddler)
and before doing so check it is not already named in that variable.
You can just change the action for it to do nothing, the recursion
will then move on with the next in line.
I have an algorithm (in a button) where I actually place the "all
members" variable into each tiddler as a field called
branch-branchname in your case this would be
thread-threadname thus each tiddler knows all its predecessors. The
thread name can be based on the first tiddler. This would allow
multiple threads to cross the same tiddlers without interfering with
the other thread. Since you know all the members of the thread you
could store the full thread in any tiddler.
Just some ideas
Tony

Hello,
want to show the title of a chain of tiddlers which mention the
next on in a field called thread.
This works fine like this
\define plotchain()
<$set name="chain" value="JJ/Das merkwürdige Tier">
$(chain)$
<<reku>>
</$set>
\end
\define chainer() [[$(chain)$]]
\define reku()
<$list filter="[list[$(chain)$!!thread]]
[list[$(chain)$!!storylink]]" variable="chain">
<<chainer>>
<<reku>>
</$list>
\end
<$vars chain="JJ/Das merkwürdige Tier">
<<chainer>>
<<reku>>
</$vars>
But if someone builds a cirle this crashes the wiki.
Is there a way of limiting recursions e.g. by using a filter with
math-operators?
Thanks!
Jan
