th-reify-many provides functions for recursively reifying top level declarations. The main intended use case is for enumerating the names of datatypes reachable from an initial datatype, and passing these names to some function which generates instances.

List type for Lua, with a Haskell interface.

This package provides an implementation of MurmurHash2, a good, fast, general-purpose, non-cryptographic hashing function. See https://sites.google.com/site/murmurhash/ for details. This implementation is pure Haskell, so it might be a bit slower than a C FFI binding.

Set- and Map-like types that remember the order elements were inserted

Word8 library to be used with Data.ByteString.

This Haskell library contains type definitions for Universally Unique Identifiers or UUIDs, and basic conversion functions.

This is a pretty printing library based on Wadler's paper "A Prettier Printer". It has been enhanced with support for ANSI terminal colored output using the ansi-terminal package.

This package allows you to work with WAVE and RF64 files in Haskell.

This package provides a Storable instance for pairs and triples which should be binary compatible with C99 and C++. The only purpose of this package is to provide a standard location for this instance so that other packages needing this instance can play nicely together.

A library for generating concise pretty printers based on precedence rules.

This library provides phantom types for Haskell 98, to avoid having to unsafely pass dummy arguments.

The Union/Find algorithm implements these operations in (effectively) constant-time:

1. Check whether two elements are in the same equivalence class.

2. Create a union of two equivalence classes.

3. Look up the descriptor of the equivalence class.

Random shuffle implementation, on immutable lists. Based on perfect shuffle implementation by Oleg Kiselyov.

This package provides ANSI terminal support for Haskell. It allows cursor movement, screen clearing, color output showing or hiding the cursor, and changing the title.

This package provides Haskell bindings for libcmark, the reference parser for CommonMark, a fully specified variant of Markdown. It includes bundled libcmark sources, and does not require prior installation of the C library.

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 library provides a pure Haskell implementation of the Unicode Collation Algorithm described at http://www.unicode.org/reports/tr10/. It is not as fully-featured or as performant as text-icu, but it avoids a dependency on a large C library. Locale-specific tailorings are also provided.

language-python is a Haskell library for lexical analysis, parsing and pretty printing Python code. It supports versions 2.x and 3.x of Python.

This package provides a module to use Skylighting to perform syntax highlighting and display the results in Brick-based interfaces.

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

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 package provides functions to marshal values from Haskell to Lua, and /vice versa/. . This package is part of HsLua, a Haskell framework built around the embeddable scripting language <https://lua.org Lua>.

This library provides the POSIX regex backend used by the Haskell library regex-base.

Simple yet powerful monadic streams that are used as a backbone for vector package fusion functionality.
