Synopsis

map1 :: (a -> a) -> [a] -> [a]
class Empty a where
- empty :: a
class GEmpty f where
- gempty :: f p

Documentation

strip :: Eq a => [a] -> [a] -> [a] Source #

A variant of stripPrefix that defaults to id if the prefix is not found.

map1 :: (a -> a) -> [a] -> [a] Source #

Version of map that applies the function to the first element only

class Empty a where Source #

Typeclass of things we can generate empty values of. This is used to quickly build values from parameters to PowerDNS, because you often only need a few fields. empty { someField = Just 1 , otherField = Just "foo" }
