-- | Filters a list based on a fuzzy string search
--   
--   Fuzzily is a library that filters a list based on a fuzzy string
--   search. Uses <a>TextualMonoid</a> to be able to run on different types
--   of strings.
@package fuzzily
@version 0.2.0.0


-- | Fuzzy string search in Haskell. Uses <tt>TextualMonoid</tt> to be able
--   to run on different types of strings.
module Text.Fuzzily

-- | Included in the return type of <a>match</a> and <a>filter</a>.
--   Contains the original value given, the rendered string and the
--   matching score.
data Fuzzy val prettyText

data CaseSensitivity
IgnoreCase :: CaseSensitivity
HandleCase :: CaseSensitivity
null :: TextualMonoid s => s -> Bool

-- | Returns the rendered output and the matching score for a pattern and a
--   text. Two examples are given below:

filter :: TextualMonoid text => CaseSensitivity -> (text, text) -> (value -> text) -> text -> [value] -> [Fuzzy value text]

-- | Return all elements of the list that have a fuzzy match against the

--   matches, as case insensitive.
