text: An efficient packed Unicode text type.
An efficient packed, immutable Unicode text type (both strict and lazy), with a powerful loop fusion optimization framework.
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.
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.
Efficient locale-sensitive support for text IO is also supported.
These modules are intended to be imported qualified, to avoid name clashes with Prelude functions, e.g.
import qualified Data.Text as T
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
—— RELEASE NOTES ——
Changes in 0.11.2.0:
String literals are now converted directly from the format in which GHC stores them into
Text, without an intermediate transformation through
String, and without inlining of conversion code at each site where a string literal is declared.
