Methods
LHS manipulation (see also 'Pattern')
data LHSPatternView Source #
The next patterns are ...
(This view discards PatInfo.)
lhsPatternView :: [NamedArg Pattern] -> Maybe (LHSPatternView, [NamedArg Pattern]) Source #
Construct the LHSPatternView of the given list (if not empty).
Return the view and the remaining patterns.
lhsCoreApp :: LHSCore -> [NamedArg Pattern] -> LHSCore Source #
Add applicative patterns (non-projection / non-with patterns) to the right.
lhsCoreAddSpine :: LHSCore -> [NamedArg Pattern] -> LHSCore Source #
Append patterns to LHSCore, separating with patterns from the rest.
mapLhsOriginalPatternM :: (Functor m, Applicative m) => (Pattern -> m Pattern) -> LHS -> m LHS Source #
hasCopatterns :: LHSCore -> Bool Source #
Does the LHS contain projection patterns?
Generic fold
class CPatternLike p where Source #
Generic pattern traversal.

Methods
Arguments
| :: Monoid m | |
| => (Pattern -> m -> m) | Combine a pattern and the value computed from its subpatterns. |
| -> p | |
| -> m |
Fold pattern.
default foldrCPattern :: forall m (f :: Type -> Type) q. (Monoid m, Foldable f, CPatternLike q, f q ~ p) => (Pattern -> m -> m) -> p -> m Source #
Arguments
| :: (Applicative m, Functor m) | |
| => (Pattern -> m Pattern -> m Pattern) | Combine a pattern and the its recursively computed version. |
| -> p | |
| -> m p |
Traverse pattern with option of post-traversal modification.
default traverseCPatternA :: forall (f :: Type -> Type) q m. (Traversable f, CPatternLike q, f q ~ p, Applicative m, Functor m) => (Pattern -> m Pattern -> m Pattern) -> p -> m p Source #
Arguments
| :: Monad m | |
| => (Pattern -> m Pattern) |
|
| -> (Pattern -> m Pattern) |
|
| -> p | |
| -> m p |
Traverse pattern.
default traverseCPatternM :: forall (f :: Type -> Type) q m. (Traversable f, CPatternLike q, f q ~ p, Monad m) => (Pattern -> m Pattern) -> (Pattern -> m Pattern) -> p -> m p Source #
Instances
foldCPattern :: (CPatternLike p, Monoid m) => (Pattern -> m) -> p -> m Source #
Compute a value from each subpattern and collect all values in a monoid.
Arguments
| :: (CPatternLike p, Monad m) | |
| => (Pattern -> m Pattern) |
|
| -> p | |
| -> m p |
Traverse pattern(s) with a modification before the recursive descent.
postTraverseCPatternM Source #
Arguments
| :: (CPatternLike p, Monad m) | |
| => (Pattern -> m Pattern) |
|
| -> p | |
| -> m p |
Traverse pattern(s) with a modification after the recursive descent.
mapCPattern :: CPatternLike p => (Pattern -> Pattern) -> p -> p Source #
Map pattern(s) with a modification after the recursive descent.
Specific folds.
patternQNames :: CPatternLike p => p -> [QName] Source #
Get all the identifiers in a pattern in left-to-right order.
Implemented using difference lists.
patternNames :: Pattern -> [Name] Source #
Get all the identifiers in a pattern in left-to-right order.
hasWithPatterns :: CPatternLike p => p -> Bool Source #
Does the pattern contain a with-pattern? (Shortcutting.)
numberOfWithPatterns :: CPatternLike p => p -> Int Source #
Count the number of with-subpatterns in a pattern?
hasEllipsis' :: CPatternLike p => p -> AffineHole Pattern p Source #
Compute the context in which the ellipsis occurs, if at all. If there are several occurrences, this is an error. This only counts ellipsis that haven't already been expanded.
reintroduceEllipsis :: ExpandedEllipsis -> Pattern -> Pattern Source #
splitEllipsis :: IsWithP p => Int -> [p] -> ([p], [p]) Source #
