Arguments
| :: (Monad m, Fresh m) | |
| => Bool | Freshen variable references in abstracted terms |
| -> Transform m | The transformation to apply to the subtrees |
| -> Transform m |
Apply a transformation on the subtrees of an term
(>->) :: Monad m => Transform m -> Transform m -> Transform m infixr 6 Source #
Apply two transformations in succession
(>-!->) :: Monad m => Transform m -> Transform m -> Transform m infixr 6 Source #
Apply two transformations in succession, and perform a deepseq in between.
unsafeTopdownR :: Rewrite m -> Rewrite m Source #
Apply a transformation in a topdown traversal. Doesn't freshen bound variables
bottomupR :: Fresh m => Transform m -> Transform m Source #
Apply a transformation in a bottomup traversal
unsafeBottomupR :: Fresh m => Transform m -> Transform m Source #
Apply a transformation in a bottomup traversal. Doesn't freshen bound variables
(!->) :: 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.
bottomupWhenR :: Fresh m => ([CoreContext] -> Term -> m Bool) -> Transform m -> Transform m Source #
Only traverse downwards when the assertion evaluates to true
