# The codo-notation package

Requires the `TemplateHaskell`

and `QuasiQuotes`

extensions.

Example 1:

{-# LANGUAGE TemplateHaskell #-} {-# LANGUAGE QuasiQuotes #-} import Control.Comonad import Language.Haskell.Codo foo :: (Comonad c, Num a) => c a -> a foo = [codo| x => extract x + 1 |]

Example 2:

import Data.Monoid instance Monoid Double where mempty = 0.0 mappend = (+) differentiate f = ((f 0.001) - f 0) / 0.001 minima :: (Double -> Double) -> Bool minima = [codo| f => f' <- differentiate f f'' <- differentiate f' (extract f' < 0.001) && (extract f'' > 0) |]

Further explanation of the syntax can be found in the following (short) paper: http://www.cl.cam.ac.uk/~dao29/drafts/codo-notation-orchard-ifl12.pdf with a numer of examples.

Further examples can be found here: https://github.com/dorchard/codo-notation.
