uses for lines, token properties?
The documentation seems sparse to nonexistent on the subject of the lines and tokens property types. And I've seen reference to a tuple property type, but it's not an option using the UI. Could someone enlighten me as to the uses of these properties? I know I can iterate thru lines, and if I knew more about parsing strings in the Zope environment I could probably use them as I would like (generating links to anchors in a document body [that I'll hard code anchors into]).(He said, sneakily embedding yet another question...) Hints, pointers to documentation or code or examples? Thanks.

Tokens are just a list of words, lines are a list of lines. In each case you can scan through them. If you need spaces use lines. I think Ztables does tuples but I haven't had time to look at it yet. Here is some code that I originally stole from zope.org. Don't tell! :) <!--#if menu_contents--> <H4><!--#var title_or_id--></h4> <p> <!--#in menu_contents--> <!--#if sequence-item--> <!--#var expr="REQUEST.set('sc', _.string.split(_vars['sequence-item'],'|'))" fmt=""--> <!--#if expr="PATH_INFO == sc[1]"--> <IMG WIDTH="8" HEIGHT="12" ALIGN="top" SRC="<!--#var BASE1-->/images/arrow" BORDER="0" VALIGN="center"> <STRONG> <!--#var expr="sc[0]"--><BR></STRONG> <!--#else--> <IMG WIDTH="8" HEIGHT="12" ALIGN="top" SRC="<!--#var BASE1-->/images/blank" BORDER="0" VALIGN="center"> <A HREF="<!--#var BASE1--><!--#var expr="sc[1]"-->"> <!--#var expr="sc[0]"--></A><BR> <!--#/if--> <!--#/if--> <!--#/in--> </P> <!--#/if menu_contents--> menu_contents is a lines property of the folder. If it doesn't exist is is inherited. So you only need to declare it when you want the menu to change. Each line is a menu item and a URL seperated by a '|'. The code splits it. It even checks if a URL is the current URL and puts in a pointer and the menu item in bold. (Full credit to zope.org, It would have taken me forever to come up with this!) Phil A.

This code should help with this, too!
