There’d been some discussions about this before. A straightforward macro like this can cause problems if not used carefully.
There are some subtle assumptions that filter execution is deterministic (ie, a given filter string will evaluate to the same list every time it is executed in the context of the same tiddler store values). For example, the list widget re-evaluates the filter each time it is refreshed, and detects changes to the list. If there were a randomising filter operator then the filter would be deemed to have changed every time, leading to continuous repeated refreshing of the list widget content. Matt Lauber has contributed a shuffle operator that should be more robust, but has yet to be finished off: https://github.com/Jermolene/TiddlyWiki5/pull/3712 <https://github.com/Jermolene/TiddlyWiki5/pull/3712> Best wishes Jeremy > On 23 Apr 2020, at 15:07, TonyM <[email protected]> wrote: > > Hubert, > > Thanks for sharing ! > > Tony > > On Thursday, 23 April 2020 22:24:22 UTC+10, Hubert wrote: > OK, I've written this quick and dirty one-liner JavaScript macro that takes > two arguments: min and max (ideally integers; any floats are floored down on > output).
