This package provides an API to Haddock, the documentation-generation tool for Haskell libraries.

This library provides free monads, which are useful for many tree-like structures and domain specific languages. If f is a Functor then the free Monad on f is the type of trees whose nodes are labeled with the constructors of f. The word "free" is used in the sense of "unrestricted" rather than "zero-cost": Free f makes no constraining assumptions beyond those given by f and the definition of Monad.

wordexp(3) wrapper library for Haskell to perform word expansion like a posix-shell.

This package provides a pipe-based interface to the Aspell program (no dynamic linking required).

This Haskell library provides a type class for the error function, erf, and related functions. Instances for Float and Double.

This package provides a simple XML library for Haskell.

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 defines the type class MonadBaseControl, a subset of MonadBase into which generic control operations such as catch can be lifted from IO or any other base monad.

Brick helps you write terminal user interfaces (TUIs). You write an event handler and a drawing function and the library does the rest.

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.

This library provides tools for fast Unicode 12.1.0 normalization in Haskell (normalization forms C, KC, D, and KD).

This library provides fast base64 encoding and decoding for Haskell ByteStrings.

Type classes for convenient marshalling and calling of Lua functions.

This library defines a propositional equality data type, shims Data.Type.Equality as well as possible for older GHC versions (< 7.8).

data a :~: b where
  Refl :: a :~: a

The module Data.Type.Equality.Hetero shims @code:~~: equality, and for compilers with PolyKinds.

This library provides monad morphism utilities, most commonly used for manipulating monad transformer stacks.

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

This package provides the following modules: Math.NumberTheory.Logarithms and Math.NumberTheory.Powers.Integer from the arithmoi package, GHC.Integer.Logarithms.Compat and Math.NumberTheory.Power.Natural, as well as some additional functions in migrated modules.

This package provides a Haskell library for working with files and directories. It includes code for pattern matching, finding files, modifying file contents, and more.

The functions for creating temporary files and directories in the Haskelll base library are quite limited. This library just repackages the Cabal implementations of its own temporary file and folder functions so that you can use them without linking against Cabal or depending on it being installed.

Get terminal window height and width without ncurses dependency.

Haskell library for both generating and consuming project templates.

ost IDEs provide the concept of a project template: instead of writing all of the code for a project from scratch, you select a template, answer a few questions, and a bunch of files are automatically generated.

project-template tries to provide a canonical Haskell library for implementing the ideal templating system.

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 module allows tokens produced by skylighting-core to be rendered as LaTeX macros.

Efficient hashing-based container types. The containers have been optimized for performance critical use, both in terms of large data quantities and high speed.
