This package provides a type-safe tool for generating XML code via quasi-quoting built on top of ghc-shakespeare.

This package provides tools to measure the memory usage of a Haskell value or function.

This library provides instances of Binary for the types defined in the vector package, making it easy to serialize vectors to and from disk. We use the generic interface to vectors, so all vector types are supported. Specific instances are provided for unboxed, boxed and storable vectors.

This library provides the natural numbers for Haskell.

This is an industrial-strength monadic parser combinator library. Megaparsec is a feature-rich package that strikes a nice balance between speed, flexibility, and quality of parse errors.

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

This package provides low-dependency functionality commonly needed by various Haskell streaming data libraries, such as conduit and pipes.

This library encourages an error-handling style that directly uses the type system, rather than out-of-band exceptions.

This package attempts to provide support for using Amazon Web Services like S3 (storage), SQS (queuing) and others to Haskell programmers. The ultimate goal is to support all Amazon Web Services.

This package provides first class functional references. In addition to the usual operations of getting, setting and composition, plus integration with the state monad, lens families provide some unique features:

• Polymorphic updating

• Traversals

• Cast projection functions to read-only lenses

• Cast toList functions to read-only traversals

• Cast semantic editor combinators to modify-only traversals

For optimal first-class support use the lens-family package with rank 2/rank N polymorphism. Lens.Family.Clone allows for first-class support of lenses and traversals for those who require Haskell 98.

This package includes backported versions of types that were added to transformers in transformers 0.3 and 0.4 for users who need strict transformers 0.2 or 0.3 compatibility to run on old versions of the platform, but also need those types.

This package provides 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.

This package provides some handy Template Haskell splices for including the current git hash and branch in the code of your project. This is useful for including in panic messages, --version output, or diagnostic info for more informative bug reports.

This package provides semigroups for Haskell. In mathematics, a semigroup is an algebraic structure consisting of a set together with an associative binary operation. A semigroup generalizes a monoid in that there might not exist an identity element. It also (originally) generalized a group (a monoid with all inverses) to a type where every element did not have to have an inverse, thus the name semigroup.

This package provides several functions to quickly search for substrings in strict or lazy ByteStrings. It also provides functions for breaking or splitting on substrings and replacing all occurrences of a substring (the first in case of overlaps) with another.

This library provides Numeric.Interval.Interval, which represents a closed, convex set of floating point values.

This Haskell library provides a place for lots of orphan instances for the ghc-vector package.

This library provides a SOCKS proxy (version 5) implementation.

This package provides a set of helper programs necessary to build the Gtk2Hs suite of libraries. These tools include a modified c2hs binding tool that is used to generate FFI declarations, a tool to build a type hierarchy that mirrors the C type hierarchy of GObjects found in glib, and a generator for signal declarations that are used to call back from C to Haskell. These tools are not needed to actually run Gtk2Hs programs.

A rich drop-in replacement for base. For details and documentation please visit the project's home page.

This is a Haskell library for writing CGI programs.

Please see the README and documentation at <https://www.stackage.org/package/githash>

This library provides the Data.Primitive.Addr module that was a part of the primitive library before primitive-0.7.0.0.

This package provides a bunch of ad hoc classes for accessing parts of a container. In practice this package is largely subsumed by the ghc-lens, but it is maintained for now as it has much simpler dependencies.
