Synopsis

Documentation

A type that implements Resolvable provides a way to perform a shallow scope-aware traversal.

Methods

rtraverse :: (Applicative f, [alg :: Alg f]) => a -> Scope -> f aSource

Instances

(Typeable a, GTraversable Resolvable a) => Resolvable a
Resolvable SrcSpan
Resolvable SrcSpanInfo
(Resolvable l, SrcInfo l, Data l) => Resolvable [Stmt l]
(Resolvable l, SrcInfo l, Data l) => Resolvable (Decl l)
(Resolvable l, SrcInfo l, Data l) => Resolvable (DeclHead l)
(Resolvable l, SrcInfo l, Data l) => Resolvable (Binds l)
(Resolvable l, SrcInfo l, Data l) => Resolvable (Match l)
(Resolvable l, SrcInfo l, Data l) => Resolvable (ConDecl l)
(Resolvable l, SrcInfo l, Data l) => Resolvable (FieldDecl l)
(Resolvable l, SrcInfo l, Data l) => Resolvable (GuardedRhs l)
(Resolvable l, SrcInfo l, Data l) => Resolvable (Type l)
(Resolvable l, SrcInfo l, Data l) => Resolvable (Exp l)
(Resolvable l, SrcInfo l, Data l) => Resolvable (Pat l)
(Resolvable l, SrcInfo l, Data l) => Resolvable (PatField l)

(Resolvable l, SrcInfo l, Data l) => Resolvable (GuardedAlt l)
Typeable a => Resolvable (Scoped a)

newtype Alg w Source

The algebra for rtraverse. It's newtype-wrapped because an implicit parameter cannot be polymorphic.

Constructors

Alg
Fields runAlg :: forall d. Resolvable d => d -> Scope -> w d

rmap :: Resolvable a => (forall b. Resolvable b => Scope -> b -> b) -> Scope -> a -> aSource

Analogous to gmap, but for Resolvable

rfoldMap :: (Monoid r, Resolvable a) => (forall b. Resolvable b => Scope -> b -> r) -> Scope -> a -> rSource

Analogous to gmap, but for Resolvable

Contains information about the node's enclosing scope. Can be accessed through the lenses: gTable, lTable, nameCtx, wcNames.

Describes how we should treat names in the current context

Constructors

Create an initial scope

Information about the names being introduced by a record wildcard

During resolving traversal, we always (lazily) construct this list when we process PRec or RecConstr, even if it doesn't contain a wildcard.

Then, if the pattern or construction actually contains a wildcard, we use the computed value.

Information about a field in the wildcard

Constructors

WcField
Fields wcFieldName :: Name () the field's simple name wcFieldOrigName :: OrigName the field's original name wcExistsGlobalValue :: Bool whether there is a global value in scope with the same name as the field but different from the field selector
