text-icu: Bindings to the ICU library

[ bsd3, data, library, text ] [ Propose Tags ]

Haskell bindings to the International Components for Unicode (ICU) libraries. These libraries provide robust and full-featured Unicode services on a wide variety of platforms.

Features include:

  • Both pure and impure bindings, to allow for fine control over efficiency and ease of use.

  • Breaking of strings on character, word, sentence, and line boundaries.

  • Access to the Unicode Character Database (UCD) of character metadata.

  • String collation functions, for locales where the conventions for lexicographic ordering differ from the simple numeric ordering of character codes.

  • Character set conversion functions, allowing conversion between Unicode and over 220 character encodings.

  • Unicode normalization. (When implementations keep strings in a normalized form, they can be assured that equivalent strings have a unique binary representation.)

  • Regular expression search and replace.

  • Security checks for visually confusable (spoofable) strings.

  • Bidirectional Unicode algorithm

  • Calendar objects holding dates and times.

  • Number and calendar formatting.

Text-ICU: Comprehensive support for string manipulation

This package provides the Data.Text.ICU library, for performing complex manipulation of Unicode text. It provides features such as the following:

  • Unicode normalization

  • Conversion to and from many common and obscure encodings

  • Date and number formatting

  • Comparison and collation

Prerequisites

This library is implemented as bindings to the well-respected ICU library (which is not bundled, and must be installed separately).

macOS

brew install icu4c
brew link icu4c --force

You might need:

export PKG_CONFIG_PATH="/usr/local/opt/icu4c/lib/pkgconfig"

Debian/Ubuntu

sudo apt-get update
sudo apt-get install libicu-dev

Fedora/CentOS

sudo dnf install unzip libicu-devel

Nix/NixOS

nix-shell --packages icu

Windows/MSYS2

Under MSYS2, ICU can be installed via pacman.

pacman --noconfirm -S mingw-w64-x86_64-icu

Depending on the age of the MSYS2 installation, the keyring might need to be updated to avoid certification issues, and pkg-config might need to be added. In this case, do this first:

pacman --noconfirm -Sy msys2-keyring
pacman --noconfirm -S mingw-w64-x86_64-pkg-config

Windows/stack

With stack on Windows, which comes with its own bundled MSYS2, the following commands give up-to-date system dependencies for text-icu-0.8.0 (tested 2022-02-07):

stack exec -- pacman --noconfirm -Sy msys2-keyring
stack exec -- pacman --noconfirm -S mingw-w64-x86_64-icu
stack exec -- pacman --noconfirm -S mingw-w64-x86_64-pkg-config

Compatibility

Upstream ICU occasionally introduces backwards-incompatible API breaks. This package tries to stay up to date with upstream, and is currently more or less in sync with ICU 70.

Minimum required version is ICU 62.
