> Helpers for

> [`optparse-applicative`](https://hackage.haskell.org/package/optparse-applicative)

> to deal with [`Data.Text`](https://hackage.haskell.org/package/text).

## Example

```haskell

import qualified Data.Text                 as T

import qualified Options.Applicative       as Opt

import qualified Options.Applicative.Text  as OptT

data Options = Options { text    :: T.Text

                       , textArg :: T.Text

                       , textOpt :: T.Text }

  deriving (Eq, Show)

optParser :: Opt.Parser Options

optParser = Options <$> Opt.argument OptT.text ( Opt.metavar "TEXT" )

                    <*> OptT.textArgument ( Opt.metavar "TEXT2" )

                    <*> OptT.textOption ( Opt.long "textopt" )

```

## Alternatives

You may want to consider using

[optparse-generic](https://github.com/Gabriel439/Haskell-Optparse-Generic-Library)

which has built-in support for Text and provides a very convient generic

interface to optparse avoiding a lot of boilerplate.
