text: An efficient packed Unicode text type.

[ bsd2, data, library, text ] [ Propose Tags ] [ Report a vulnerability ]

An efficient packed, immutable Unicode text type (both strict and lazy), with a powerful loop fusion optimization framework.

The Text type represents Unicode character strings, in a time and space-efficient manner. This package provides text processing capabilities that are optimized for performance critical use, both in terms of large data quantities and high speed.

The Text type provides character-encoding, type-safe case conversion via whole-string case conversion functions. It also provides a range of functions for converting Text values to and from ByteStrings, using several standard encodings (see the 'text-icu' package for a much larger variety of encoding functions).

Efficient locale-sensitive support for text IO is also supported.

This module is intended to be imported qualified, to avoid name clashes with Prelude functions, e.g.

import qualified Data.Text as T

Text: Fast, packed Unicode strings, using stream fusion

This package provides the Data.Text library, a library for the space- and time-efficient manipulation of Unicode text in Haskell.

Normalization, conversion, and collation, oh my!

This library intentionally provides a simple API based on the Haskell prelude's list manipulation functions. For more complicated real-world tasks, such as Unicode normalization, conversion to and from a larger variety of encodings, and collation, use the text-icu package.

That library uses the well-respected and liberally licensed ICU library to provide these facilities.

Get involved!

Please report bugs via the bitbucket issue tracker.

Master Mercurial repository:

  • hg clone http://bitbucket.org/bos/text

There's also a git mirror:

  • git clone git://github.com/bos/text.git

(You can create and contribute changes using either Mercurial or git.)

Authors

The base code for this library was originally written by Tom Harper, based on the stream fusion framework developed by Roman Leshchinskiy, Duncan Coutts, and Don Stewart.

The core library was fleshed out, debugged, and tested by Bryan O'Sullivan bos@serpentine.com, and he is the current maintainer.
