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="$(brew --prefix)/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-pkgconf

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 2023-09-30):

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

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 72.

Minimum required version is ICU 62.
