This package provides Haskell bindings to bzlib and Conduit support for streaming compression and decompression.

Long lived application data typically should not contain any thunks. This library can be used to examine values for unexpected thunks, which can then be used in assertions. This can be invaluable in avoiding memory leaks, or tracking down existing ones.

This package provides a small cross-platform library for reading and modifying the system clipboard. It uses xclip or xsel at runtime.

This package provides a basic random number generation library, including the ability to split random number generators.

This package provides tools to parse and produce literals efficiently from strict or lazy bytestrings.

This package contains basic definitions related to indexed profunctors. These are primarily intended as internal utilities to support the optics and generic-lens package families.

Protolude gives you sensible defaults for writing custom Preludes to replace the standard one provided by GHC.

Haskell-Source with Extensions (HSE, haskell-src-exts) is an extension of the standard haskell-src package, and handles most registered syntactic extensions to Haskell. All extensions implemented in GHC are supported. Apart from these standard extensions, it also handles regular patterns as per the HaRP extension as well as HSX-style embedded XML syntax.

Text.Regex.Base provides the interface API for regex-posix, regex-pcre, regex-parsec, regex-tdfa, regex-dfa.

This package provides the ShortText type which is suitable for keeping many short strings in memory. This is similar to how ShortByteString relates to ByteString.

The main difference between Text and ShortText is that ShortText uses UTF-8 instead of UTF-16 internally and also doesn't support zero-copy slicing (thereby saving 2 words). Consequently, the memory footprint of a (boxed) ShortText value is 4 words (2 words when unboxed) plus the length of the UTF-8 encoded payload.

This package provides an implementation of n-ary sums and n-ary products. The module Data.SOP is the main module of this library and contains more detailed documentation. The main use case of this package is to serve as the core of generics-sop.

The word-wrap Haskell library wraps long lines of text.

This library implements unicode-casemap, the simple, non locale-sensitive unicode collation algorithm described in RFC 5051. Proper unicode collation can be done using text-icu, but that is a big dependency that depends on a large C library, and rfc5051 might be better for some purposes.

This package provides a canonical anonymous 1-tuple type missing from Haskell for attaching typeclass instances.

There is also the OneTuple package which by using a boxed data-type provides a 1-tuple type which has laziness properties which are more faithful to the ones of Haskell's native tuples; whereas the primary purpose of Only is to provide the traditionally so named type-wrapper for attaching typeclass instances.

This library lets you write interactive programs without callbacks or side-effects. Functional Reactive Programming (FRP) uses composable events and time-varying values to describe interactive systems as pure functions. Just like other pure functional code, functional reactive code is easier to get right on the first try, maintain, and reuse. Reflex is a fully-deterministic, higher-order FRP interface and an engine that efficiently implements that interface.

Manipulate identifiers and structurally non-complex pieces of text by delimiting word boundaries via a combination of whitespace, control-characters, and case-sensitivity.

Has support for common idioms like casing of programmatic variable names, taking, dropping, and splitting by word, and modifying the first character of a piece of text.

Caution: this library makes heavy use of the text library's internal loop optimisation framework. Since internal modules are not guaranteed to have a stable API there is potential for build breakage when the text dependency is upgraded. Consider yourself warned!

This package provides fast unicode character sets for Haskell, based on complemented PATRICIA tries.

This package provides a simple network library for all your connection needs. It provides a very simple API to create sockets to a destination with the choice of SSL/TLS, and SOCKS.

ResourceT is a monad transformer which creates a region of code where you can safely allocate resources.

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.

This Haskell package aims to reexport all the non-conflicting and most general definitions from the "base" package.

This includes APIs for applicatives, arrows, monoids, foldables, traversables, exceptions, generics, ST, MVars and STM.

This package will never have any dependencies other than "base".

Versioning policy:

The versioning policy of this package deviates from PVP in the sense that its exports in part are transitively determined by the version of "base". Therefore it's recommended for the users of ghc-base-prelude to specify the bounds of "base" as well.

This package provides Type-level booleans.

This package provides efficient vector-based hashtable implementation similar to .NET Generic Dictionary implementation (at the time of 2015).

This Haskell package provides an either monad transformer.
