Hi Eric
Indeed it is a bit more tricky because I would like to use it in a FET :
<<forEachTiddler
> where
> 'tiddler.tags.contains("$1") && tiddler.tags.contains("$2") &&
> !tiddler.tags.contains("attachment")'
> sortBy
> tiddler.title
> ascending
> write
> '((index == 0) ? "" : " - ")+"<<wikify [[%0|"+tiddler.title+"]]
> text@"+tiddler.title+"$))"'
> >>
>
Because of the " of the wikify syntax I can't have it work ... I am not
sticking to FET and this case may be a limit.
Looking forward to read from you
