The MFlow package

[Tags: bsd3, library]

MFlow run stateful server processes. This version is the first stateful web framework that is as RESTful as a web framework can be.

The routes are expressed as normal, monadic haskell code in the FlowM monad. Local links point to alternative routes within this monadic computation just like a textual menu in a console application. Any GET page is directly reachable by means of a RESTful URL.

All the flow of requests and responses are coded by the programmer in a single procedure. Allthoug single request-response flows are possible. Therefore, the code is more understandable. It is not continuation based. It uses a log for thread state persistence and backtracking for handling the back button. Back button state syncronization is supported out-of-the-box

The MFlow architecture is scalable, since the state is serializable and small

The processes are stopped and restarted by the application server on demand, including the execution state (if the Wokflow monad is used). Therefore session management is automatic. State consistence and transactions are given by the TCache package.

The processes interact trough widgets, that are an extension of formlets with additional applicative combinators, formatting, link management, callbacks, modifiers, caching, byteString conversion and AJAX. All is coded in pure haskell.

The interfaces and communications are abstract, but there are bindings for blaze-html, HSP, Text.XHtml and byteString , Hack and WAI but it can be extended to non Web based architectures.

Bindings for hack, and hsp >= 0.8, are not compiled by Hackage, and do not appear, but are included in the package files. To use them, add then to the exported modules and execute cabal install

It is designed for applications that can be run with no deployment with runghc in order to speed up the development process. see http://haskell-web.blogspot.com.es/2013/05/a-web-application-in-tweet.html

This release includes:

The version 0.2 added better WAI integration, higher level dynamic Widgets, content management, multilanguage, blaze-html support, stateful ajax for server-side control, user-defined data in sessions and widget requirements for automatic installation of scripts, CSS and server flows.
