My informal test, running the code below on TiddlyWiki.com, suggests that <currentTiddler> may be twice as fast as is[current]. Minutes and seconds are posted at the top and bottom of the process loop for comparison.
<<now "mm:0ss">> <$list filter="1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20"> <$list filter="[all[tiddlers+shadows]]"> <$list filter="[<currentTiddler>has[text]]"> .</$list> </$list> </$list> <<now "mm:0ss">> On Sunday, June 11, 2017 at 8:31:32 AM UTC-7, Danielo Rodríguez wrote: > > Hello, > > I was creating some template tiddlers when I suddenly discovered myself > using <currentTiddler> a lot within list widgets. > > This is what was natural for me at that moment, but I just remembered that > I before I normally use the filter operator [is[current]] or [all[current]] > and the doubt appeared.
