1. package Color

   Color spaces and conversions between them Please see the README on GitHub at https://github.com/lehins/Color#readme

2. package FontyFruity

   A true type file format loader A haskell Truetype file parser. You can load a font file and extract some curves to be drawed with a library like Rasterific .

3. package Rasterific

   A pure haskell drawing engine. Rasterific is a vector drawing library (a rasterizer) implemented in pure haskell. Can render vector graphics to an image and export vector data to PDF.

4. package STMonadTrans

   A monad transformer version of the ST monad A monad transformer version of the ST monad. Warning! This monad transformer should not be used with monads that can contain multiple answers, like the list monad. The reason is that the state token will be duplicated across the different answers and this causes Bad Things to happen (such as loss of referential transparency). Safe monads include the monads State, Reader, Writer, Maybe and combinations of their corresponding monad transformers.

5. package abstract-deque

   Abstract, parameterized interface to mutable Deques. An abstract interface to highly-parameterizable queues/deques. Background: There exists a feature space for queues that extends between:

   • simple, single-ended, non-concurrent, bounded queues
   • double-ended, threadsafe, growable queues
   ... with important points inbetween (such as the queues used for work-stealing). This package includes an interface for Deques that allows the programmer to use a single API for all of the above, while using the type-system to select an efficient implementation given the requirements (using type families). This package also includes a simple reference implementation based on IORef and Data.Sequence.

6. package aeson-casing

   Tools to change the formatting of field names in Aeson instances. Tools to change the formatting of field names in Aeson instances. This includes CamelCasing, Pascal Casing and Snake Casing.

7. package aeson-gadt-th

   Derivation of Aeson instances for GADTs Template Haskell for generating ToJSON and FromJSON instances for GADTs. See README.md for examples.

8. package amqp

   Client library for AMQP servers (currently only RabbitMQ) Client library for AMQP servers (currently only RabbitMQ)

9. package annotated-exception

   Exceptions, with checkpoints and context. Please see the README on Github at https://github.com/parsonsmatt/annotated-exception#readme

10. package ap-normalize

    Self-normalizing applicative expressions An applicative functor transformer to normalize expressions using (<$>), (<*>), and pure into a linear list of actions. See ApNormalize to get started.
