The haskell-src package provides support for manipulating Haskell source code. The package provides a lexer, parser and pretty-printer, and a definition of a Haskell abstract syntax tree (AST). Common uses of this package are to parse or generate Haskell 98 code.

This is a set of macros to be used when writing Haskell FFI. They were designed to be able to fully describe C interfaces, so that hsc2hs can extract from them all Haskell code needed to mimic such interfaces. All Haskell names used are automatically derived from C names, structures are mapped to Haskell instances of Storable, and there are also macros you can use with C code to help write bindings to inline functions or macro functions.

This package provides an interface to the directory package for users of path. It also implements some missing stuff like recursive scanning and copying of directories, working with temporary files/directories, and more.

This library provides a continuation-based, backtracking, logic programming monad. An adaptation of the two-continuation implementation found in the paper "Backtracking, Interleaving, and Terminating Monad Transformers" available online.

This Haskell package provides interfaces and helper functions for the ghc-persistent package.

The Newtype typeclass represents the packing and unpacking of a newtype, and allows you to operate under that newtype with functions such as ala. Generics support was added in version 0.4, making this package a full replacement for the original newtype package, and an alternative to newtype-th.

This package extends https://hackage.haskell.org/package/process. It allows you to read process input and output as ByteStrings or Text, or write your own ProcessOutput instance. It also provides lazy process input and output, and a ProcessMaker class for more flexibility in the process creation API.

Compatibility layer for Data.Array.Byte providing boxed wrappers for ByteArray and MutableByteArray and relevant instances for GHC < 9.4.

This library provides an implementation of the older blaze-builder interface in terms of the new builder that shipped with bytestring-0.10.4.0. This implementation is mostly intended as a bridge to the new builder, so that code that uses the old interface can interoperate with code that uses the new implementation.

Utilities to parse, print, diff, and analyse data in CoNLL-U, a format used in linguistics to represent the syntactic annotation of sentences. See https://universaldependencies.org/format.html

This package provides tools to parse Haskell sources to the template-haskell abstract syntax.

This library provides file handling utilities for Haskell.

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.

This package provides a simple logging abstraction that allows multiple back-ends.

This package implements the bijection between JSON and CBOR defined in the CBOR specification, RFC 7049.

The conduit package is a solution to the streaming data problem, allowing for production, transformation, and consumption of streams of data in constant memory. It is an alternative to lazy I/O which guarantees deterministic resource handling, and fits in the same general solution space as enumerator/iteratee and pipes.

This library makes it easy to implement monads with tricky control flow. This is useful for: writing web applications in a sequential style, programming games with a uniform interface for human and AI players and easy replay capabilities, implementing fast parser monads, designing monadic DSLs, etc.

This Haskell package provides striped pooling abstraction for managing flexibly-sized collections of resources such as database connections.

The base library exposes the hGetEcho and hSetEcho functions for querying and setting echo status, but unfortunately, neither function works with MinTTY consoles on Windows. This library provides an alternative interface which works with both MinTTY and other consoles.

This package enables integration of terminal screen state in html pages.

Provides a small set of helper functions for testing Megaparsec parsers with Hspec.

This package contains basic primitives for the Foundation set of packages.

This Haskell package provides a replacement for Data.Conduit.List, as well as a convenient Conduit module.

This package provides Haskell bindings to bibutils, a library that interconverts between various bibliography formats using a common MODS-format XML intermediate.
