Synopsis
type AssocList k v = [(k, v)]
lookupDef :: Eq k => v -> k -> AssocList k v -> v
lookup1 :: Eq k => k -> AssocList k [e] -> [e]
hasEntry :: Eq k => k -> AssocList k v -> Bool
addEntry :: Eq k => k -> v -> AssocList k v -> AssocList k v
addEntries :: Eq k => AssocList k v -> AssocList k v -> AssocList k v
delEntry :: Eq k => k -> AssocList k v -> AssocList k v
delEntries :: Eq k => [k] -> AssocList k v -> AssocList k v
Documentation
type AssocList k v = [(k, v)] | Source
lookupDef :: Eq k => v -> k -> AssocList k v -> v | Source
lookup with default value
lookup1 :: Eq k => k -> AssocList k [e] -> [e] | Source
lookup with empty list (empty string) as default value
hasEntry :: Eq k => k -> AssocList k v -> Bool | Source
test for existence of a key
addEntry :: Eq k => k -> v -> AssocList k v -> AssocList k v | Source
add an entry, remove an existing entry before adding the new one at the top of the list, addEntry is strict
addEntries :: Eq k => AssocList k v -> AssocList k v -> AssocList k v | Source
add a whole list of entries with `addEntry`
delEntry :: Eq k => k -> AssocList k v -> AssocList k v | Source
delete an entry, delEntry is strict
delEntries :: Eq k => [k] -> AssocList k v -> AssocList k v | Source
delete a list of entries with `delEntry`
