-- | Library to deal with rhythmicity of short sequences
--   
--   The library deals with the model similar to the one given at the work
--   <a>https://oleksandrzhabenko.github.io/uk/rhythmicity/PhLADiPreLiO.Eng.21.pdf</a>
--   and
--   <a>https://hackage.haskell.org/package/phonetic-languages-simplified-examples-array</a>
@package rhythmic-sequences
@version 0.2.0.0


-- | Functions for Rhythmicity.MarkerSeqs module that additionally
--   "catches" some hashing logics so that they can influence in the
--   predictable way the peculiarities of the results for PhLADiPreLiO.
module Rhythmicity.BasicF
hashPosLF2 :: Int8 -> [Integer] -> Integer
hashBalancingLF2 :: Int8 -> [Integer] -> Integer
hashBasicLF2 :: Int8 -> [Integer] -> Integer


-- | Data and algorithmic basics to evaluate rhythmicity of the lists of
--   <a>Ord</a> instance data type. Similar to
--   <tt>phonetic-languages-rhythmicity</tt> on Hackage.
module Rhythmicity.MarkerSeqs

-- | The similar function is since <tt>base-4.16.0.0</tt> in the
--   <tt>Numeric</tt> module. Is not used further, is provided here mostly
--   for testing purposes.
showBin :: Int -> [Char]

-- | Basic counting of the same bits in the <a>Bits</a> arguments.
unionCount :: Bits a => a -> a -> Integer

-- | Some idea function to evaluate the rhythmicity data. Is not used
--   further in the package, can be thought of as an alternative way of
--   computation.
countWeightsQs :: Foldable t => [t a -> Int] -> [t a] -> [[Int]]

-- | Data type used to provide somewhat 'array sorting with its indices'.
data Sort2 a
S2 :: Int8 -> a -> Sort2 a
[id] :: Sort2 a -> Int8
[val] :: Sort2 a -> a

-- | Data type to contain the needed for hashing algorithm information
--   about the sorted 'array sorting with its indices'.
data ASort3 a
As3 :: Int8 -> Int8 -> a -> ASort3 a
[id3] :: ASort3 a -> Int8
[orD] :: ASort3 a -> Int8
[val3] :: ASort3 a -> a

-- | Split the list into lists of <tt>n</tt> elements where <tt>n</tt> is
--   the first parameter.
splitF :: Int -> [a] -> [[a]]

-- | Function to get basic data for hash-based evaluation of the
--   rhythmicity of the list data. Is used internally in the
--   <a>countHashesG</a>. Provided here mostly for testing purposes.
getHashes2 :: Ord a => Int8 -> [Int8] -> [a] -> [[Integer]]

-- | Convert hashes into basic simler data to evaluate rhythmicity of the
--   list data.
countHashesPrioritized :: Bits b => [[b]] -> [[Integer]]

-- | Mostly for testing.
count1Hashes :: Ord a => Int8 -> [Int8] -> [a] -> Integer

-- | Data type to encode the changes that are introduced by the position of
--   the group of values in general sequence to the general result of the
--   <tt>createHashesG</tt> function. If the second parameter in the
--   <a>HashCorrections</a> is 1 then the result is more sensitive to
--   beginning of the line; if it is set to 2 then the result is more
--   sensitive to ending of the line; if it is greater than 2 then the
--   result is sensitive to some user weights provided as the first
--   parameter to <a>HashCorrections</a> and otherwise the computation
--   result does not depend on the first parameter to
--   <a>HashCorrections</a> (this one can be considered the basic option
--   for the computation).
data HashCorrections
H :: [Int8] -> Int8 -> HashCorrections
hashCorrections2F :: HashCorrections -> Int8 -> [Integer] -> Integer

-- | If the second parameter in the <a>HashCorrections</a> is 1 then the
--   result is more sensitive to beginning of the line; if it is set to 2
--   then the result is more sensitive to ending of the line; if it is
--   greater than 2 then the result is sensitive to some user weights
--   provided as the first parameter to <a>HashCorrections</a> and
--   otherwise the computation result does not depend on the first
--   parameter to <a>HashCorrections</a> (this one can be considered the
--   basic option for the computation).
hashList :: HashCorrections -> [Int8]

-- | If you would like to specify just your own values then specify the
--   <a>Lexeme</a> "3..." where instead of dots specify some digits that
--   are the beginning of the [<a>Int8</a>] list in <a>HashCorrections</a>.
--   Caution: &gt; readHashCorrections . show $ xs /= xs &gt; show .
--   readHashCorrections $ xs /= xs in general case. The default value is
--   <tt>H [0,0..] 0</tt>.
readHashCorrections :: String -> HashCorrections

-- | This is used to provide the second and the third argument to
--   <a>countHashesG</a> function. The default value is <tt>(2,[2,1])</tt>
--   that should be related to disyllables metrical feet.
grouppingR :: String -> (Int8, [Int8])

-- | General implementation of the hash-based algorithm to evaluate the
--   level of rhythmicity of the list data. The relatively greater result
--   (for PhLADiPreLiO) corresponds to greater detected periodicity.
countHashesG :: Ord a => HashCorrections -> Int8 -> [Int8] -> [a] -> [Integer]

-- | Provided for testing.
createNewHash :: [Integer] -> Integer

-- | General implementation of the second hashing of the data for the
--   algorithm.
createHashG :: (Int8 -> [Integer] -> Integer) -> Int8 -> [Integer] -> Integer

-- | A variant of the <a>createHashG</a> that actually must be equal to the
--   <a>createNewHash</a> for the second argument lists with less than 8
--   elements. For greater values is not correctly defined, so do not use
--   it for the lists with 8 or more elements in them. Actually should be
--   equal to <a>createNewHash</a> for the second argument.
createNHash :: [Int8] -> [Integer] -> Integer

-- | Function to filter the elements by the second parameter of the
--   <a>ASort3</a> data and then to get the first ones.
idList :: Eq a => [Int8] -> [ASort3 a] -> [Int8]

-- | Function to create bitwise representation of the intermediate data for
--   the algorithm. Should be very optimized to run fast.
toNum :: [Int8] -> Integer

-- | The alternative implementation of the <a>toNum</a> (on the Linux
--   x86_64 for some CPU is slower than the former one).
