class (Functor m, MonadIO m, ExceptionMonad m, HasDynFlags m) => GhcMonad (m :: Type -> Type) where Source #

A monad that has all the features needed by GHC API calls.

In short, a GHC monad

allows embedding of IO actions,
can log warnings,
allows handling of (extensible) exceptions, and
maintains a current session.

If you do not use Ghc or GhcT, make sure to call initGhcMonad before any call to the GHC API functions can occur.
