Right now, getclassmetatags("myclass") and getvariablemetatags("myvar")
return an slist of all the tags for their respective class or variable.
In 3.9.0, I found myself needing a specific tag value instead of all of
them, so I was doing
regex_replace(nth(grep("^foo=.*", getclassmetatags("myclass")), 0),
"^foo=", "", "T")
to get the value of the "foo=bar" tag of "myclass". So I would love to
have an optional second argument getclassmetatags("myclass", "foo") and
getvariablemetatags("myvar", "foo") that give me a slist of the specific
tag values, removing the key. What do you think? It would be backwards
compatible and fairly easy to implement.
