Data.Unicode.NormalizationInsensitive

This module is intended to be imported qualified. May I suggest:

import           Data.Unicode.NormalizationInsensitive  ( NI )
import qualified Data.Unicode.NormalizationInsensitive as NI

Documentation

data NI s

A NI s provides Normalization Insensitive comparison for the string-like type s (for example: String, Text, ByteString, etc.).

Note that NI s has an instance for IsString which together with the OverloadedStrings language extension allows you to write normalization insensitive string literals as in:

> ("\12399\12441" :: NI Text) == ("\12400" :: NI Text)
True

Instances

Eq s => Eq (NI s)

Data s => Data (NI s)

Ord s => Ord (NI s)

(Read s, Normalizable s) => Read (NI s)

Show s => Show (NI s)

(IsString s, Normalizable s) => IsString (NI s)

(Monoid s, Normalizable s) => Monoid (NI s)

NFData s => NFData (NI s)

Hashable s => Hashable (NI s)

Normalizable (NI s)

Typeable (* -> *) NI

mk :: Normalizable s => s -> NI s

Make the given string-like value normalization insensitive.

original :: NI s -> s

Retrieve the original string-like value.

map :: Normalizable s2 => (s1 -> s2) -> NI s1 -> NI s2

Transform the original string-like value but keep it normalized.

class Normalizable s where

Class of string-like types that support normalization.

Methods
