Re: [Haskell-cafe] IO in HApps handler ?

Subject: IO in HApps handler ? I am trying to add a handler that would run an external command in HApps 0.8.8, and I got a type issue I do not know how to get around..

can we have IO in a handler ?

http://www.haskell.org/haskellwiki/HAppS_tutorial#Application "The MACID monad lets you update your state and *schedule* side-effects. To be clear, MACID is not in the IO monad so you cannot execute side effects, you can only schedule them. The framework takes care of making sure they are executed at-least-once (if they can be completed by a deadline you specify)." I don't know the specifics. Tim Newsham http://www.thenewsh.com/~newsham/
