What is this thing?
A library for handling ASCII text.
What are the goals of this project?
Totality by default
Partial functions (and type classes which provide them) will not be included: everything is total. When we include anything unsafe, it will be explicitly firewalled into its own module, behind a newtype.
No boolean blindness
Boolean blindness is not
a good thing, for all the reasons listed in the link. Whenever possible, we'll
try and give more useful information than a
Compatibility with the
We want match the API of the
text package exactly. If you know how to use
you'll know how to use this package too. Exceptions are made for places where
text is either partial or boolean-blind.
Discoverability, documentation and user-friendliness
In addition to documenting everything with Haddocks, we have over 250 doctests,
which provide executable examples of how the API can be used, and how it will
behave. We aim to clarify every corner case left by the documentation of
text, and care strongly about making the API easy to follow, learn and
We currently use doctests, but plan to add support for more testing. No such thing as too much!
As far as possible, we aim to depend on GHC boot packages only. When we introduce more dependencies, we do it only when we have to. This way, we ensure this package builds quickly and doesn't 'lag' more than necessary due to GHC version changes.

What does this run on?
We support the latest three releases of GHC. Currently, these are:
