Re: [Haskell-beginners] MonadThrow, MonadReader and shake

I've swapped the args above, it should be:

liftIO $ runReaderT (toRuchePath attachements) stateBeforeCallingShake

Hello, I was struggling with strange errors :). Now it works. thanks a lot. I am just wondering if the best it not to add a parameter to my toRuchePath function and avoid the Reader Monad. this would simplify the code I gess.

With additional `MonadThrow Action` and `MonadReader Beamline Action` instances it should work. But the MonadReader one is really specific to your use case.

I will try also this. thansk a lot. Frederic
