Found this: <<tiddler {{"SomeTiddler".text!=0?"SomeTiddler":""}}>>
This works by itself so I'm trying to put in in the fET (which usually does
not have a problem with simple tiddler macros):
<<forEachTiddler where 'tiddler.tags.contains("foo")'
write '
"*[["+tiddler.title+"]]\n
** <<tiddler {{"+tiddler.title+".text!=0?"+tiddler.title+":"" $)) \n"'
>>
this gives error ( <<forEachTiddler ...>>: SyntaxError: missing ; before
statement )
but, as explained initially, my hope is for the result to be either *nothing
*or **text\n
I.e the bullets and newline are included in the result from the tiddler
macro. Maybe it's possible using "with:" and sending in bullets and newline
as parameters...?
...or if there's any better solution all together (hopefullystill with the
fET tho as it in actual application it contains more.)
Thoughts?
