Description
A few helpers to work with the AST annotations
- removeAnnotations :: Traversable t => t a -> t ()
- reannotate :: Traversable t => (a -> b) -> t a -> t b
- addExtraAnnotationField :: Traversable t => b -> t a -> t (a, b)
- removeExtraAnnotationField :: Traversable t => t (a, b) -> t a
- assignUniqueIds :: Traversable t => Int -> t a -> (t (a, Int), Int)
- class HasAnnotation a where
- getAnnotation :: a b -> b
Documentation
removeAnnotations :: Traversable t => t a -> t ()Source
Removes annotations from a tree
reannotate :: Traversable t => (a -> b) -> t a -> t bSource
Changes all the labels in the tree to another one, given by a function.
addExtraAnnotationField :: Traversable t => b -> t a -> t (a, b)Source
add an extra field to the AST labels (the label would look like
(a, b) )
removeExtraAnnotationField :: Traversable t => t (a, b) -> t aSource
remove an extra field
Arguments
| :: Traversable t | |
| => Int | starting id |
| -> t a | tree root |
| -> (t (a, Int), Int) |
Assigns unique numeric (Int) ids to each node in the AST. Returns a pair: the tree annotated with UID's and the last ID that was assigned.
