Hello Torsten Thank you for the demo that it is actually possible to make it work! Thus I managed to build help topics for my app. It really very easy to add help topics! The source of the error was that I had spaces before the ! marks which mark a section title. Reason is that I had just copied the wiki text example from the help text to do the test. So this is clearly a bug leading people to think that wiki style help does not work. See at the bottom for a wiki string which works (just spaces removed in front of !) [1] Good that this is compatible with the Pillar syntax which I am using for other things. It offers many options, for example the class side method #helpString can pull out part or the whole of the class comment. Regards Hannes [1] ------------------------------------------------------------------------------------------------ Example of wiki style help text to be added on the class side The help browser parses this text when being opened Notes - There are no spaced in front of the ! marks - The class WikiStyleHelpBuilder does the job of parsing a subset of the Pillar/Pier syntax and building up the help nodes tree. ------------------------------------------------------------------------------------------------ helpString <wikiStyleHelp: #'My help book'> ^ ' !

Hi Hannes,

make sure - it is a class side method - you have no spaces before the ! marks - you reopen the help browser

then it works and creates subtopics. See screenshot attached.

Bye T.
