PS As Posted elsewhere this is the method I use for default parameters
I often use a variation of this when making my own macros to allow it to use current tiddler or another if provided. Basically it provides a default of the current tiddler *However you could use this for any input parameter.* \define mymacro(tiddlername) <$set name=selected-tiddler value="$tiddlername$" emptyValue=<< currentTiddler>> > Action: <<selected-tiddler>> </$set> \end <<mymacro>> <<mymacro "another tiddler">> This also illustrates another design principal, I almost always write my macros to operate on the current tiddler such that if placed in wikitext a list without a variable set the macros operate on the changing current tiddler, or it can be given a specific tiddler. If I use a variable in the list it uses the currentTiddler and the list will not change the currentTiddler value Regards Tony On Monday, April 1, 2019 at 9:40:08 PM UTC+11, TonyM wrote: > > S s > > Also in my request to format variables in the view widget, Jeremy points > out plans to introduce a format operator into filters.
