Data.Generics.Biplate

Description

DEPRECATED: Use Data.Generics.Uniplate.Operations instead.

Requires multi-parameter type classes, so is no longer Haskell 98. These operations are easier to use and construct than the equivalent Data.Generics.UniplateStrOn methods, but perform the same operation.

It is recommended that instead of importing this module, you import one of the following modules, to construct instances:

Data.Generics.PlateDirect - does not require overlapping instances, highest performance but requires O(n^2) instances in the worst case.
Data.Generics.PlateTypeable - requires the Data.Typeable class for all data structures.
Data.Generics.PlateData - requires Data.Generics and the Data class, which is only available on GHC, but automatically infers instances.

Synopsis

descendBi :: Biplate from to => (to -> to) -> from -> from
descendBiM :: (Monad m, Biplate from to) => (to -> m to) -> from -> m from
universeBi :: Biplate from to => from -> [to]
childrenBi :: Biplate from to => from -> [to]
transformBi :: Biplate from to => (to -> to) -> from -> from
transformBiM :: (Monad m, Biplate from to) => (to -> m to) -> from -> m from
rewriteBi :: Biplate from to => (to -> Maybe to) -> from -> from
rewriteBiM :: (Monad m, Biplate from to) => (to -> m (Maybe to)) -> from -> m from
contextsBi :: Biplate from to => from -> [(to, to -> from)]
holesBi :: Biplate from to => from -> [(to, to -> from)]
biplateList :: Biplate from to => from -> ([to], [to] -> from)
