Thank you Diego. A follow up question, is it possible to detect if a string is only whitespace? As in, " "? Such "string" would consist of no characters but at the same time it would not evaluate to nothing, so the following reveal syntax would not detect it:
<$reveal state="!!input" type="nomatch" text=""/> I feel this could be accomplished with regex, but I'm no expert. What I'm trying to do is foolproof my text inputs against accidental empty strings because the consequences are not elegant so to speak :) Thank you again, Hubert On Monday, 2 December 2019 15:43:05 UTC, Diego Mesa wrote: > > Hey Hubert, > > Unless Im missunderstanding something, you can use the split operator and > the join operator to accomplish this: > > <$list filter="[[a black cat hides under a chair]split[ ]join[]]"> > <<currentTiddler>> > </$list> > > returns: ablackcathidesunderachair > > > On Monday, December 2, 2019 at 9:18:33 AM UTC-6, Hubert wrote: >> >> Hello, >> >> I'm looking for something beyond trim, a filter operator that would >> remove *all *spaces from an input (not just trailing spaces), like here: >> >> <$list filter="[[a black cat hides under a chair]whitespaceremove[]]"> >> <<currentTiddler>> >> </$list> >> >> Where the output would ideally be: *ablackcathidesunderachair* >> >> Is this possible? >> >> Thank you, >> Hubert >> >> -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
