Constructors

Hole

Hole

Ctxt f [Term f v] (Ctxt f v) [Term f v]

Non-empty context

Instances

(Eq v, Eq f) => Eq (Ctxt f v)

Methods

(==) :: Ctxt f v -> Ctxt f v -> Bool

(/=) :: Ctxt f v -> Ctxt f v -> Bool

(Ord v, Ord f) => Ord (Ctxt f v)

Methods

compare :: Ctxt f v -> Ctxt f v -> Ordering

(<) :: Ctxt f v -> Ctxt f v -> Bool

(<=) :: Ctxt f v -> Ctxt f v -> Bool

(>) :: Ctxt f v -> Ctxt f v -> Bool

showList :: [Ctxt f v] -> ShowS

Important operations

ofTerm :: Term f v -> Pos -> Maybe (Ctxt f v)

Create a context from a term by placing the hole at a specific position.

apply :: Ctxt f v -> Term f v -> Term f v

Apply a context to a term (i.e., replace the hole in the context by the term).
