intoRegularSublists :: [Int] -> [a] -> [[a]] Source #
Splits the input second argument into sublists each one containing the n
elements where the number is taken as the
sequential element in the first argument starting from the left to the right. If the number is less than 1 then the
corresponding sublist is empty. If all the elements in the first argument are less than 1 then returns an infinite lazy list of
[] as its elements (probably not the needed case). When all the elements of the first argument ends and there are elements in
the second argument being not already processed then the function reinitializes itself with the prior first argument and the
rest of the unprocessed elements in the second argument. This leads to the *cycling behaviour*.
Similar functions are in the list-grouping
and split
packages, but they do not have cycling behaviour and have another realization.
:: Monad m | |
=> (a -> m [Int]) | A monadic function to obtain the argument for the regularization. |
-> a | An initial element (seed) for the monadic function. |
-> [b] | A list to be splitted into the sublists. |
-> m [[b]] |
A monadic variant of the intoRegularSublists
where the first argument is taken from the monadic function.
