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!")If you desire it, there are also monomorphic versions of the showb function available in the submodules of Text.Show.Text. See the naming conventions page for more information.
Support for automatically deriving TextShow instances can be found in the TextShow.TH and TextShow.Generic modules.
