This package implements a language similar to YAML or JSON but with fewer special cases and fewer dependencies. It emphasizes layout structure for sections and lists, and requires quotes around strings.

This package provides types and combinators for linear algebra on free vector spaces.

This library provides peek and poke functions for network byte order.

This package defines a class for types with a default value, and provides instances for types from the base, containers, dlist and old-locale packages.

Chell is a simple and intuitive library for automated testing. It natively supports assertion-based testing, and can use companion libraries such as chell-quickcheck to support more complex testing strategies.

This package provides variants of the show and print functions that do not escape non-ascii characters.

This package provides a library implementing the XDG Base Directory spec.

Lua module wrapping Text.DocLayout.

This package is a Haskell library for the representation, parsing, and pretty-printing of GLSL 1.50 code.

This package provides testing utilities that are useful in conjunction with the Validity typeclass.

More complex tests for chell.

This package provides a quasiquoter for non-interpolated strings, texts and bytestrings.

Module with function for creating, modifying, and extracting files from zip archives.

This package provides a type called @DMap@ which generalizes @Data.Map.Map@, allowing keys to specify the type of value that can be associated with them.

Rose (n-ary) trees with both upwards- (i.e. cached) and downwards-traveling (i.e. accumulating) monoidal annotations. This is used as the core data structure underlying the diagrams framework, but potentially has other applications as well.

Hslogger lets each log message have a priority and source be associated with it. The programmer can then define global handlers that route or filter messages based on the priority and source. It also has a syslog handler built in.

This package provides two simple conduit wrappers around STM channels: a source and a sink.

Types that are parametric on a functor are like Barbies that have an outfit for each role. This package provides the basic abstractions to work with them comfortably.

This package provides strict versions of some standard Haskell data types, such as pairs, Maybe and Either. It also contains strict IO operations.

This package provides a library to parse and render YAML documents.

This package provides access to platform dependent file locking APIs. There are alternative file locking packages:

• GHC.IO.Handle.Lock in base >= 4.10 is good enough for most use cases. However, uses only Handles so these locks cannot be used for intra-process locking.

• ghc-filelock doesn't support OFD locking.

This library provides various semigroups, specialized containers and a general map/reduce framework for Haskell.

This library defines an existential type Some'. . @ data Some f where \ Some :: f a -> Some f @ . in few variants, and utilities to work with it. . If you are unsure which variant to use, use the one in "Data.Some" module.

This library provides implementations of concurrent FIFO queues (for both general boxed and primitive unboxed values) that are fast, perform well under contention, and offer a Chan-like interface. The library may be of limited usefulness outside of x86 architectures where the fetch-and-add instruction is not available.
