Question

I want to list the siblings of a topic.

If I could easily get back the parent topic name (not a link, just the name), I think this would be fairly simple. However, ParentTopicVariable implies that getting the parent topic name is nontrivial (unless this has changed in a year).

Does anyone have a chunk of (Search and Spreadsheet?) code that will give me the siblings of a given topic?

VarMETA ("parent") didn't seem to work for me on TWiki 4.2, so I went with this:

<!--
   * Set PARENT = %SEARCH{"%TOPIC%" nonoise="on" scope="topic" format="$parent"}%
-->
Siblings:
%SEARCH{"META\:TOPICPARENT.*\"%PARENT%\"" type="regex" nonoise="on" format="   * [[$topic]]" excludetopic="%TOPIC%"}%

I couldn't get the sequence of escapes worked out to get that onto one line, but it works.
