Hi Tobias In general, I am guessing usage cases and writing filters which might be of use. The reason I adopted the filter expression method for list operators in the first instance was for this very reason -- it is difficult to guess what users will do with lists.
With this approach, the $action-listops widget remains simple, the complexity being confined to the filter expression. As usage cases become better defined, it may be necessary to add other filters and may also be possible to eliminate a few. regards On Tuesday, 27 October 2015 11:31:19 UTC+2, Tobias Beer wrote: > > Hi Metabele, > > >> I have updated the append[] and prepend[] operators to understand a >> prefix and suffix.
