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.

Please refer to the package description on Hackage for more information.

Get involved!

Please report bugs via the github issue tracker.

Master git repository:

  • git clone git://

There's also a Mercurial mirror:

  • hg clone

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


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, and he is the current maintainer.

You can’t perform that action at this time.
