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).

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 (see Data.Text). It also provides a range of functions for converting Text values to and from ByteStrings, using several standard encodings (see Data.Text.Encoding).

Efficient locale-sensitive support for text IO is also supported (see Data.Text.IO).

These modules are intended to be imported qualified, to avoid name clashes with Prelude functions, e.g.

import qualified Data.Text as T

ICU Support

To use an extended and very rich family of functions for working with Unicode text (including normalization, regular expressions, non-standard encodings, text breaking, and locales), see the text-icu package based on the well-respected and liberally licensed ICU library.

Flags

Manual Flags

Name	Description	Default
developer	operate in developer mode	Disabled
simdutf	use simdutf library, causes Data.Text.Internal.Validate.Simd to be exposed	Enabled
pure-haskell	Don't use text's standard C routines NB: This feature is not fully implemented. Several C routines are still in use. When this flag is true, text will use pure Haskell variants of the routines. This is not recommended except for use with GHC's JavaScript backend. This flag also disables simdutf.	Disabled
extendedbenchmarks	Runs extra benchmarks which can be very slow.	Disabled

Use -f <flag> to enable a flag, or -f -<flag> to disable that flag. More info

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. Transition from UTF-16 to UTF-8 is by Andrew Lelechenko.
