This package provides the ability to adapt to locale conventions such as date and time formats.

This Haskell package aims to be an RFC3986 compliant URI parser that uses ByteStrings for parsing and representing the URI data.

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.

Turtle is a reimplementation of the Unix command line environment in Haskell so that you can use Haskell as both a shell and a scripting language. Features include:

• Batteries included: Command an extended suite of predefined utilities.

• Interoperability: You can still run external shell commands.

• Portability: Works on Windows, OS X, and Linux.

• Exception safety: Safely acquire and release resources.

• Streaming: Transform or fold command output in constant space.

• Patterns: Use typed regular expressions that can parse structured values.

• Formatting: Type-safe printf-style text formatting.

• Modern: Supports text and system-filepath.

Read "Turtle.Tutorial" for a detailed tutorial or "Turtle.Prelude" for a quick-start guide. Turtle is designed to be beginner-friendly, but as a result lacks certain features, like tracing commands. If you feel comfortable using turtle then you should also check out the Shelly library which provides similar functionality.

This package provides functions to prevent or capture writing to stdout and other handles.

This library provides a type-safe embedded domain specific language (EDSL) for SQL queries that works with SQL backends as provided by ghc-persistent. Its language closely resembles SQL, so you don't have to learn new concepts, just new syntax, and it's fairly easy to predict the generated SQL and optimize it for your backend.

This package contains the C sources of LPeg, as well as some tiny Haskell helper to load the package. . <http://www.inf.puc-rio.br/~roberto/lpeg/>

This package profides a class for encoding and decoding UTF8 strings with instances for several common types. It also includes several functions for working with UTF8. It aims to be lightweight, depending only on Base and including only one module.

This package provides an URI manipulation interface. In network-2.6 the Network.URI module was split off from the network package into this package.

GHC 7.4 gave us the ability to talk about ConstraintKinds. They stopped crashing the compiler in GHC 7.6. This package provides a vocabulary for working with them.

Package providing a Choice type of labeled booleans to mitigate the Boolean blindness problem, which refers to the problem that boolean literals on their own aren't very informative (e.g., what does True mean in a given context?).

This package is a compatibility package for a singleton data type . > data Solo a = Solo a . Note: it's not a @newtype@ . @Solo@ is available in @base-4.16@ (GHC-9.2).

The zip-archive library provides functions for creating, modifying, and extracting files from zip archives in Haskell.

Checkers wraps up the expected properties associated with various standard type classes as QuickCheck properties. It also provides some morphism properties, arbitrary instances, and generator combinators for common data types.

Converting time to and from IS0 8601 text. Specifically the RFC3339 profile.

This package provides a version of ghc-hspec-expectations generalized to MonadIO.

Automatically discover and run Hspec tests . <http://hspec.github.io/hspec-discover.html>
