text-show offers a replacement for the Show typeclass intended for use with Text instead of Strings. This package was created in the spirit of bytestring-show.
At the moment, text-show provides instances for most data types in the array, base, bytestring, and text packages. Therefore, much of the source code for text-show consists of borrowed code from those packages in order to ensure that the behaviors of Show and TextShow coincide.
For most uses, simply importing TextShow will suffice:
module Main where
import TextShow
main :: IO ()
main = printT (Just "Hello, World!")See also the naming conventions page.
Support for automatically deriving TextShow instances can be found in the TextShow.TH and TextShow.Generic modules.
