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?
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.
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...)
This code should help with this, too!
