Operational +Control.Applicative

package operational
package
This library makes it easy to implement monads with tricky control flow. This is useful for: writing web applications in a sequential style, programming games with a uniform interface for human and AI players and easy replay capababilities, implementing fast parser monads, designing monadic DSLs, etc. See the project homepage http://haskell.org/haskellwiki/Operational for a more detailed introduction and features. Related packages: MonadPrompt http://hackage.haskell.org/package/MonadPrompt. Version 0.2.2.1
package free-operational
package
A reimplementation of the operational package (http://hackage.haskell.org/package/operational) using free monads (from http://hackage.haskell.org/package/free). This implements ideas discussed here: * http://stackoverflow.com/questions/14263363/is-operational-really-isomorphic-to-a-free-monad * http://www.reddit.com/r/haskell/comments/17a33g/free_functors_the_reason_free_and_operational_are/ To understand the basic concepts you can do no better than read Heinrich Apfelmus' operational tutorial: * http://apfelmus.nfshost.com/articles/operational-monad.html In addition to that, this package supplies operational-style modules for Applicative, Alternative and MonadPlus. Applicative and Alternative programs easily admit of static analysis.  See these references for discussion and examples: * http://gergo.erdi.hu/blog/2012-12-01-static_analysis_with_applicatives/ (discussion: http://www.reddit.com/r/haskell/comments/143wpd/static_analysis_with_applicatives/) * http://paolocapriotti.com/blog/2013/04/03/free-applicative-functors/ (discussion: http://www.reddit.com/r/haskell/comments/1bnql3/free_applicative_functors_icfp_submission/) See Control.Applicative.Operational for the bulk of the documentation. Control.Alternative.Operational also has some significant examples. Version 0.5.0.0
package minioperational
package
This package provides tiny implementation of operational monad. Version 0.4.2
