text-show: Efficient conversion of values into Text

[ bsd3, library, text ] [ Propose Tags ]

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.

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.

text-show only provides instances for data types in the following packages:

This policy is in place to keep text-show's dependencies reasonably light. If you need a TextShow instance for a library that is not in this list, it may be covered by the text-show-instances library.

Flags

Automatic Flags
NameDescriptionDefault
base-4-9

Use base-4.9 or later.

Enabled
template-haskell-2-11

Use template-haskell-2.11.0.0 or later.

Enabled
new-functor-classes

Use a version of transformers or transformers-compat with a modern-style Data.Functor.Classes module. This flag cannot be used when building with transformers-0.4, since it comes with a different version of Data.Functor.Classes.

Enabled
integer-gmp

When building with a version of GHC older than 9.0, depend on the integer-gmp library. You can disable this if you do not wish to link against GMP, but at the expense of having a slower TextShow Natural instance.

Enabled

Use -f <flag> to enable a flag, or -f -<flag> to disable that flag. More info
