tagref()

tagref(<tag>)
istag(<string>)
listtags([<object>])
tagmatch(<pattern>)

Functions over the tags @tag and @ltag keep. A tag is looked up as #<tag> is: the world’s tag of that name, else one of your own.

tagref() returns the dbref <tag> names, or #-1. A leading # is allowed. RhostMUSH calls it tag(); here tag() writes HTML.
istag() returns 1 when <string> is # followed by a tag that names an object, else 0.
listtags() returns every tag as <tag>|<dbref>. Given <object>, it returns the names of the tags that name it.
tagmatch() returns the names of the tags that match the wildcard <pattern>.

listtags() and tagmatch() need the config.admin permission. Each covers the world’s tags and your own.

> think tagref(weather) [istag(#weather)] [listtags(#42)]
#42 1 weather

Output: weather names #42.
