Referring to: https://tiddlywiki.com/prerelease/#is%20Operator It states !is[tiddler] is equal to is[missing]
In page: https://tiddlywiki.com/prerelease/#all%20Operator It states missing is all non-existent tiddlers to which there is at least one hard link <https://tiddlywiki.com/prerelease/#Hard%20and%20Soft%20Links> Can I check if a title is a tiddler or NOT? I mean does it check also for system and shadow tiddlers? If so, does the documentation needs to be revised? Example Check if all names refer to an existing tiddler (shadow, system, tiddler) <$list filter="[subfilter<names>] +[!is[missing]]"> Mohammad -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
