Data.Repa.Nice

Documentation

class Nicer a where

Convert some value to a nice form.

In particular:

• Nested Arrays are converted to nested lists, so that they are easier to work with on the ghci console.
• Lists of characters are wrapped into the Str data type, so that they can be pretty printed differently by follow-on processing.

As ghci automatically pretty prints lists, using nice is more fun than trying to show the raw Repa array representations.
