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
This library is implemented as bindings to the well-respected ICU library (which is not bundled, and must be installed separately).
brew install icu4c
brew link icu4c --force
You might need:
export PKG_CONFIG_PATH="$(brew --prefix)/opt/icu4c/lib/pkgconfig"
sudo apt-get update
sudo apt-get install libicu-dev
sudo dnf install unzip libicu-devel
nix-shell --packages icu
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
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
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.
Please report bugs via the github issue tracker.
