Hi Jeremy, Speaking of sequences, let's say I have a few titles in the list field of a ToC tiddler : [[Introduction]] [[My second chapter]] [[Here is the third one]].
I'd like to count the number of tiddlers before the current tiddler, in order to display for instance "Chapter *2* : My second chapter" from <$count filter="[all[current]operation-that-returns-the-sublist-upto-the-current-tiddler]"/>. Is there a way to achieve this from the set of operators available? Best regards, Xavier. -- Xavier Cazin On Mon, May 12, 2014 at 5:03 PM, Jeremy Ruston <[email protected]>wrote: > Hi Alain > > In 5.0.11 you'll be able to use the new before/after filter operators to > do what you want.
