allR Source #

Arguments

:: forall m. Monad m 
=> Transform m

The transformation to apply to the subtrees

-> Transform m 

Apply a transformation on the subtrees of an term

(!->) :: Rewrite m -> Rewrite m -> Rewrite m infixr 5 Source #

Only apply the second transformation if the first one succeeds.

(>-!) :: Rewrite m -> Rewrite m -> Rewrite m infixr 5 Source #

Only apply the second transformation if the first one fails.

(>-!->) :: Monad m => Transform m -> Transform m -> Transform m infixr 6 Source #

Apply two transformations in succession, and perform a deepseq in between.

(>->) :: Monad m => Transform m -> Transform m -> Transform m infixr 6 Source #

Apply two transformations in succession

bottomupR :: Monad m => Transform m -> Transform m Source #

Apply a transformation in a bottomup traversal

repeatR :: Rewrite m -> Rewrite m Source #

Keep applying a transformation until it fails.

topdownR :: Rewrite m -> Rewrite m Source #

Apply a transformation in a topdown traversal

bottomupWhenR :: Monad m => (TransformContext -> Term -> m Bool) -> Transform m -> Transform m Source #

Only traverse downwards when the assertion evaluates to true
