Type ReadTerm

type ReadTerm src ss ts = Source src => Inj_Source (TypeVT src) src => Inj_Source (KindK src) src => Inj_Source (AST_Type src) src => Constable (->) => Name2Type src -> CtxTy src ts -> AST_Term src ss -> Either (Error_Term src) (TermVT src ss ts)

Convenient type alias for readTerm and related functions.

readTerm :: forall src ss ts. ReadTerm src ss ts

Read a TermVT from and AST_Term.

teVar :: forall ss src ts. Source src => NameTe -> CtxTy src ts -> Either (Error_Term src) (TermVT src ss ts)

teApp :: Source src => Constable (->) => Term src ss ts '[Proxy (a :: Type), Proxy (b :: Type)] (() #> ((a -> b) -> a -> b))

reduceTeApp :: AST_Term src ss -> AST_Term src ss

Reduce number of Token_Term_App in given AST_Term by converting them into BinTree2.

NOTE: Token_Term_App exists only to handle unifix operators applied to arguments.

Type ReadTermCF

newtype ReadTermCF src ss

Like ReadTerm, but CtxTe-free.

Useful in readTermWithCtx to help GHC's type solver, which "Cannot instantiate unification variable with a type involving foralls".

ReadTermCF

Fields

• unReadTermCF :: forall ts. ReadTerm src ss ts

readTermWithCtx :: Foldable f => Source src => Inj_Source (TypeVT src) src => Inj_Source (KindK src) src => Inj_Source (AST_Type src) src => Constable (->) => f (NameTe, TermT src ss '[] '[]) -> Name2Type src -> AST_Term src ss -> Either (Error_Term src) (TermVT src ss '[])

Like readTerm but with given context, and no more.

readTermWithCtxPush :: Foldable f => f (NameTe, TermT src ss '[] '[]) -> (forall ts'. ReadTerm src ss ts') -> ReadTerm src ss ts

Like readTerm but with given context.

readTermWithCtxPush1 :: (NameTe, TermT src ss '[] '[]) -> (forall ts'. ReadTerm src ss ts') -> ReadTerm src ss ts

Like readTerm but with given TermT pushed onto CtxTy and CtxTe.

readTermWithCtxClose :: (forall ts'. ReadTerm src ss ts') -> Source src => Inj_Source (TypeVT src) src => Inj_Source (KindK src) src => Inj_Source (AST_Type src) src => Constable (->) => Name2Type src -> AST_Term src ss -> Either (Error_Term src) (TermVT src ss '[])

Close a ReadTerm context.
