\> get lambda

###Get Lambda

Get Lambda is a framework for writing Interactive Fiction in Haskell.

It aims to provide 

 + a good decoupled way of writing IF

 + text-based intermediate protocol for more representation freedom

 + means to implement complex logic in a clean fashion

 + and some more stuff

The engine concept can be described with this listing:

```

module Engine

( Object,

  Trait,

  Relation,

  Action,

) where

import Data.Map (Map)

import qualified Data.Map as Map

import Data.Set (Set)

import qualified Data.Set as Set

-- This module exports kinds, traits, relations, actions definitions

type Key     = String

data Value   = String | Number | Action

type KV      = Map.Map Key Value

type Action  = ([String] -> KV) -> KV

data Object  = Object { id :: String, kind :: String, traits :: Set.Set Trait, state :: KV }

data Trait   = Trait { trait :: String, actions :: Map.Map String Action }

data Relation a b = Relation { relation :: String, graph :: [(a -> b) -> Bool] }

```
