Create Tags

constructTag :: NonEmpty TagNode -> Tag

deconstructTag :: HasCallStack => Tag -> NonEmpty TagNode

Creating Tag Trees

tagTree :: (Eq a, Default a) => Map Tag a -> Forest (TagNode, a)

Construct the tree from a list of hierarchical tags

Searching Tags

mkTagPattern :: Text -> TagPattern

mkTagPatternFromTag :: Tag -> TagPattern

tagMatch :: TagPattern -> Tag -> Bool

Working with Tag Trees

foldTagTree :: (Eq a, Default a) => Forest (TagNode, a) -> Forest (NonEmpty TagNode, a)
