def ProofWidgets.Util.joinArrays {m : Type → Type} [Monad m] [Lean.MonadRef m] [Lean.MonadQuotation m] (arr : Array Lean.Term) : m Lean.Term

Sends #[a, b, c] to `(term| $a ++ $b ++ $c)

def ProofWidgets.Util.foldInlsM {α β : Type u_1} {m : Type u_1 → Type u_2} [Monad m] (arr : Array (α ⊕ β)) (f : Array α → m β) : m (Array β)

Collapse adjacent inl (_ : α)s into a β using f. For example, #[.inl a₁, .inl a₂, .inr b, .inl a₃] ↦ #[← f #[a₁, a₂], b, ← f #[a₃]].

def Lean.PrettyPrinter.Delaborator.delabListLiteral {α : Type} (elem : DelabM α) : DelabM (Array α)

Delaborate the elements of a list literal separately, calling elem on each.

def Lean.PrettyPrinter.Delaborator.delabArrayLiteral {α : Type} (elem : DelabM α) : DelabM (Array α)

Delaborate the elements of an array literal separately, calling elem on each.

class MonadSaveCtx (m : Type → Type) (n : outParam (Type → Type)) : Type 1

Certain monad transformers such as ReaderT and StateT/StateRefT provide additional context (read-only) and state (mutable). MonadSaveCtx m n means that m is a stack of contexts/states on top of n. It provides a way to suspend an m-action by saving the "current" value of this stack.

For example, m = Lean.MetaM is a stack of contexts and states on top of n = EIO Lean.Exception. Thus we have saveCtxM : Lean.MetaM α → Lean.MetaM (EIO Lean.Exception α).

• saveCtxM {α : Type} : m α → m (n α)

  Transform an action x : m α into an action m (n α) that

  • saves the current context/state of m; and
  • returns an action y : n α that would use the saved context/state if run. Note that because y no longer has access to m's state, any StateT changes that it makes when you run it later will be discarded.
