Optics as an abstract interface This package makes it possible to define and use Lenses, Traversals, Prisms and other optics, using an abstract interface. See the main module Optics for the documentation. This is the "batteries-included" variant with many dependencies; see the optics-core package and other optics-* dependencies if you need a more limited dependency footprint.
-
Binding to the Pango text rendering engine. This package provides a wrapper around the Pango C library that allows high-quality rendering of Unicode text. It can be used either with Cairo to output text in PDF, PS or other documents or with Gtk+ to display text on-screen.
-
Tests for Persistent Tests for Persistent. This is only for use in developing libraries that should conform to the persistent interface, not for users of the persistent suite of database libraries.

Safety for the pipes ecosystem This package adds resource management and exception handling to the pipes ecosystem. Notable features include:
- Resource Safety: Guarantee finalization using finally, bracket and more
- Exception Safety: Even against asynchronous exceptions!
- Laziness: Only acquire resources when you need them
- Promptness: Finalize resources early when you are done with them
- Native Exception Handling: Catch and resume from exceptions inside pipes
- No Buy-in: Mix resource-safe pipes with unmanaged pipes using hoist

A variety of alternative parser combinator libraries. A variety of alternative parser combinator libraries, including the original HuttonMeijer set. The Poly sets have features like good error reporting, arbitrary token type, running state, lazy parsing, and so on. Finally, Text.Parse is a proposed replacement for the standard Read class, for better deserialisation of Haskell values from Strings.

Reliable, persistent, fast priority queues. A fast, reliable priority queue implementation based on a binomial heap.
-
Weaken applicative functor on products Weaken applicative functor which allows only product construction. Product constructions and deconstructions are always isomorphic.
-
A lens-based implementation of protocol buffers in Haskell. The proto-lens library provides an API for protocol buffers using modern Haskell language and library patterns. Specifically, it provides:
- Composable field accessors via lenses
- Simple field name resolution/overloading via type-level literals
- Type-safe reflection and encoding/decoding of messages via GADTs
-
Alternative arbitrary instance for Text The usual Arbitrary instance for Text (in quickcheck-instances) only has single-byte instances and so isn't an ideal representation of a valid UTF-8 character. This package has generators for one-, two- and three-byte UTF-8 characters (all that are currently in use).
