This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.

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"
