Hi,
Does anyone know why the ‘Created date’ 00010101000000000 (01.01.0001) in tiddlers cannot be filtered in the list below. While other dates such as 1000010100000000 or 16000229000000000 does work.
<$vars day={{{[<now 0MM0DD>]}}}><$list filter="[all[tiddlers]![xyz]!created[00010101000000000]!tag[Quote]!tag[*Function]!is[system]!sort[created]]! :filter[{!!created}else[]format:date[0MM0DD]match<day>]" emptyMessage="...">
I’m not exactly sure what you are trying to do and I didn’t try your filter with actual tiddlers. It might help if you wrote out in words the logic you are trying to produce.
I also see several filter syntax problems:
![xyz] needs some kind of filter operator before the [xyz] operand. Maybe !match[xyz]
! following the end of the first filter run: ...!sort[created]]!
:filter[...] filter run, the initial reference to {!!created} will ALWAYS have a value. If the created field doesn’t exist, it will produce a blank value. Thus, the else[] that follows it will never be triggered. Perhaps you mean: :filter[{!!created}format:date[0MM0DD]match<day>]???-e
Hi Erik, thanks for the reply.
I have to admit, I don’t know much about programming and I’ve just scraped together the programming rules shown on this forum.
The wiki is a “what happened today in history” version.
Each tiddler has a footer that shows all other events on that day, regardless of the year.
The displayed listing filters out the tiddlers I don’t want to see in the footer.
And you know what, it works fine. Except when I use a tiddler with the created date 01.01.0001. As mentioned, all other dates work fine.
I know I can use a tag for tiddlers with that date, but I really want to use this date.
I hope it’s a bit clearer now what I mean.
