Predicates on lists.

Please see the README on GitHub at https://github.com/pgujjula/list-utilities/tree/master/list-predicate#readme.

list-predicate

list-predicate is a library for predicates (True/False queries) on lists.

Features

The following features have been implemented and extensively tested:

• allEqual, allEqualBy: Whether all the elements of a list are equal
• sorted, sortedBy: Whether the elements are in sorted order.
• allUnique, allUniqueBy: Whether the elements are all unique.
• ascSequential, descSequential: Whether a list of Enums is ascending or descending sequentially (one-by-one)
• palindrome: Whether the list is a palindrome

Full documentation can be built with Haddock (see instructions below). Once this package is added to Hackage, documentation will be available there as well.

git clone https://github.com/pgujjula/list-utilities/list-predicate
