Item10183: FOR from ForEachPlugin does not work with start="1" stop="1" step="1".

The most simpel case of an FOR loop does not work (at least not on my system...).

%FOR{"VAR" start="1" stop="1" step="1"}% $VAR %NEXT{"VAR"}%

The topic never opens. Seems to become an endless loop.

This is pretty fatal, when you work with lists in combination with FOR. You never know when a list has only one item and if it has, the topic including this loop crashes.

Hi Enrik, thanks for the bug report. I'm not aware of anybody maintaining ForEachPlugin but maybe somebody will do it.

This is a very old plugin which uses commonTagsHandler for macro expansion. A more reliable way to process lists is use FilterPlugin or Foswiki 1.1's new VarFORMAT macro.

Please check out Support.Faq39 to see how to migrate from ForEachPlugin

Yes Paul, you are right, ForEach is old and replacable. But if i don't miss something, varFOR is not!

My case: I need to generate Lines for the EasyTimelinePlugin. A valid line looks like:

from:date till:date color:string text:string

I don't know how many items i have in advance. The dates, text and colors are a result from ActionTrackerPlugin and are each written into a list.

So i have 4 Lists: from_list , till_list , color_list , text_list. Currently, i'm using a nested code like this:

FOR{every item}

from:CALC{$LISTITEM(itemnumber,from_list)} till:CALC{$LISTITEM(itemnumber,till_list)} color:CALC{$LISTITEM(itemnumber,color_list)} text:CALC{$LISTITEM(itemnumber,text_list)}

NEXT ITEM

I don't see a way to do this elegantly with either FORMATLIST or varFORMAT. Is there a way?

Friendly,

I'm so sorry! Didn't see the $index token for type="string" operations. With this token, it's equivalent! Sorry again and thank you very much!
