@hackage iconv-typed0.2.0.0

Type safe iconv wrapper

An experiment in bringing type safety to the iconv package.

Usage Example

This is almost a drop-in replacement. Compare the original code from iconv:

module Main where

import Codec.Text.IConv

main :: IO ()
main = print $ convert "UTF-8" "LATIN1" "hello"

With the equivalent in `iconv-typed`:

module Main where

import Codec.Text.IConv.Typed

main :: IO ()
main = print $ convert @"UTF-8" @"LATIN1" "hello"

As a result, this code will compile and run only if the passed encoding resolves to a supported encoding (as retrieved at compile time by calling "iconv -l"). For example, the following won't compile:

main = print $ convert @"UFT-8" "LATIN1" "hello"

As UFT is mispelled.

Using GHC < 8.0 that doesn't supports TypeInType? No problem, we've got you covered!

module Main where

import Codec.Text.IConv.Typed

main :: IO ()
main = print $ convert (E :: E "UTF-8") (E :: E "LATIN1") "hello"
