isUnique function is to check whether the given element is unique in the list or not.

It returns Nothing when the element does not present in the list. Examples:

isUnique 'f' "foo bar" == Just True
isUnique 'o' "foo bar" == Just False
isUnique '!' "foo bar" == Nothing

Since 0.4.7.2

isRepeated is a reverse function to isUnique

Since 0.4.7.2

removeDuplicates removes the duplicates of elements. Example:

removeDuplicates "foo bar" == " abrfo"

repeated finds only the elements that are present more than once in the list. Example:

 repeated  "foo bar" == "o"

The repeatedBy function behaves just like repeated, except it uses a user-supplied equality predicate.

repeatedBy (>2) "This is the test line" == " stei"

unique gets only unique elements, that do not have duplicates.

unique  "foo bar" == " abrf"

allUnique checks whether all elements of the list are unique

allUnique "foo bar" == False
allUnique ['a'..'z'] == True
allUnique [] == True (!)

Since 0.4.7.2

count of each element in the list. Example:

count "This is the test line" == [(' ',4),('s',3),('T',1),('t',3),('e',3),('h',2),('i',3),('l',1),('n',1)]

count_ of each elements in the list, it sorts by their number. Example:

 count_ "This is the test line" == [('n',1),('l',1),('T',1),('h',2),('i',3),('e',3),('t',3),('s',3),(' ',4)]
