Rattus

Contents

Description

The bare-bones Rattus language. To program with streams and events, you can use Rattus.Stream and Rattus.Events; to program with Yampa-style signal functions, you can use Rattus.Yampa.

Synopsis

Rattus language primitives

Strict data types

Annotation

data Rattus Source #

Use this type to mark a Haskell function definition as a Rattus function:

{-# ANN myFunction Rattus #-}

Or mark a whole module as consisting of Rattus functions only:

{-# ANN module Rattus #-}

If you use the latter option, you can mark exceptions (i.e. functions that should be treated as ordinary Haskell function definitions) as follows:

{-# ANN myFunction NotRattus #-}

By default all Rattus functions are checked for use of lazy data types, since these may cause memory leaks. If any lazy data types are used, a warning is issued. These warnings can be disabled by annotating the module or the function with AllowLazyData

{-# ANN myFunction AllowLazyData #-}

{-# ANN module AllowLazyData #-}

Applicative operators

(|*|) :: Box (a -> b) -> Box a -> Box b Source #

Applicative operator for Box.

(|**) :: Stable a => Box (a -> b) -> a -> Box b Source #

Variant of |*| where the argument is of a stable type..

(<*>) :: O (a -> b) -> O a -> O b Source #

Applicative operator for O.

(<**) :: Stable a => O (a -> b) -> a -> O b Source #

Variant of <*> where the argument is of a stable type..

box for stable types

box' :: Stable a => a -> Box a Source #

Variant of box for stable types that can be safely used nested in recursive definitions or in another box.
