name: transformers version: 0.4.0.0 license: BSD3 license-file: LICENSE author: Andy Gill, Ross Paterson maintainer: Ross Paterson category: Control synopsis: Concrete functor and monad transformers description: A portable library of functor and monad transformers, inspired by the paper \"Functional Programming with Overloading and Higher-Order Polymorphism\", by Mark P Jones, in /Advanced School of Functional Programming/, 1995 (). . This package contains: . * the monad transformer class (in "Control.Monad.Trans.Class") and IO monad class (in "Control.Monad.IO.Class") . * concrete functor and monad transformers, each with associated operations and functions to lift operations associated with other transformers. . The package can be used on its own in portable Haskell code, in which case operations need to be manually lifted through transformer stacks (see "Control.Monad.Trans.Class" for some examples). Alternatively, it can be used with the non-portable monad classes in the @mtl@ or @monads-tf@ packages, which automatically lift operations introduced by monad transformers through other transformers. build-type: Simple extra-source-files: changelog cabal-version: >= 1.6 source-repository head type: darcs location: http://code.haskell.org/~ross/transformers flag ApplicativeInBase description: Use the current base package, including Applicative and other Functor classes. library if flag(ApplicativeInBase) build-depends: base >= 2 && < 6 else build-depends: base >= 1.0 && < 2, special-functors >= 1.0 && < 1.1 exposed-modules: Control.Applicative.Backwards Control.Applicative.Lift Control.Monad.IO.Class Control.Monad.Signatures Control.Monad.Trans.Class Control.Monad.Trans.Cont Control.Monad.Trans.Except Control.Monad.Trans.Error Control.Monad.Trans.Identity Control.Monad.Trans.List Control.Monad.Trans.Maybe Control.Monad.Trans.Reader Control.Monad.Trans.RWS Control.Monad.Trans.RWS.Lazy Control.Monad.Trans.RWS.Strict Control.Monad.Trans.State Control.Monad.Trans.State.Lazy Control.Monad.Trans.State.Strict Control.Monad.Trans.Writer Control.Monad.Trans.Writer.Lazy Control.Monad.Trans.Writer.Strict Data.Functor.Classes Data.Functor.Compose Data.Functor.Constant Data.Functor.Identity Data.Functor.Product Data.Functor.Reverse Data.Functor.Sum
