codaCoda,
I have updated the content of "&" to return text only
<$text text={{{ [all[current]split[ ]] +[join[]] }}}/>
*Important guidance* is
- the "filter" given to the transclusion needs each value to be treated
as a title hence
- $:/string/ [<var>] / [{!!fieldname}] [[/suffix/]] [all[current]]
- except for literals without white space, we need to wrap it in at
least one [ ]
I think typically we are forced to use wikify still rather than set or vars
to get such variables to operate in a filter.
<$set name=ghost-tiddler value={{{ $:/ghost/ [all[current]] || & }}}>
<$link to=<<ghost-tiddler>>/>
<$list filter="[<ghost-tiddler>has[title]]" emptyMessage="No ghost">
Ghost tiddler <<ghost-tiddler>> exists
</$list>
</$set>
This does just not result in <<ghost-tiddler>> "$:/ghost/*currentTiddler*"
I have raised this issue
<https://github.com/Jermolene/TiddlyWiki5/issues/5110>, but Saq has an
argument that wikify is a poor performer.
Regards
Tony
