  - embDef :: QName -> b
  }

- class GetDefs a where
  - getDefs :: MonadGetDefs m => a -> m ()

# Documentation

getDefs' :: (GetDefs a, Monoid b) => (MetaId -> Maybe Term) -> (QName -> b) -> a -> b Source #

`getDefs' lookup emb a` extracts all used definitions (functions, data/record types) from `a`, embedded into a monoid via `emb`. Instantiations of meta variables are obtained via `lookup`.

Typical monoid instances would be `[QName]` or `Set QName`. Note that `emb` can also choose to discard a used definition by mapping to the unit of the monoid.

type GetDefsM b = ReaderT (GetDefsEnv b) (Writer b) Source #

Inputs to and outputs of `getDefs'` are organized as a monad.

data GetDefsEnv b Source #

class GetDefs a where Source #

Getting the used definitions.

Note: in contrast to `foldTerm` `getDefs` also collects from sorts in terms. Thus, this is not an instance of `foldTerm`.
