This is a modified version of wl-pprint, which was based on Wadler's paper "A Prettier Printer". This version allows the library user to annotate the text with semantic information, which can later be rendered in a variety of ways.

This package provides a binary serialization library, similar to binary, that introduces an isolate primitive for parser isolation, and labeled blocks for better error messages.

Old-time is a package for backwards compatibility with the old time library. For new projects, the newer time library is recommended.

This library provides Pure Haskell solver routines for use by the diagrams framework. It currently includes routines for finding real roots of low-degree (n < 5) polynomials, and solving tridiagonal and cyclic tridiagonal linear systems.

This package provides the core modules underlying diagrams, an embedded domain-specific language for compositional, declarative drawing.

Haskeline wrapper for GHCi-like REPL interfaces. Composable with normal mtl transformers.

Basic file IO operations like Prelude, but for OsPath'.

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

This is the IRC core library for glirc. The client is available in its own glirc package.

This package provides instances to push and receive any datatype encodable as JSON to and from the Lua stack.

This tiny package contains the class ObjectName, which corresponds to the general notion of explicitly handled identifiers for API objects, e.g. a texture object name in OpenGL or a buffer object name in OpenAL.

This library provides functions for parsing and pretty printing Roman numerals. Because the notation of Roman numerals has varied through the centuries this package allows for some customisation using a configuration that is passed to the conversion functions.

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.

The YAML 1.2 format provides a much richer data-model and feature-set than the JavaScript Object Notation format. However, sometimes it's desirable to ignore the extra capabilities and treat YAML as if it was merely a more convenient markup format for humans to write JSON data. To this end this module provides a compatibility layer atop ghc-hsyaml ,which allows decoding YAML documents in the more limited JSON data-model while also providing convenience by reusing ghc-aeson's FromJSON instances for decoding the YAML data into native Haskell data types.

This package contains a MonadRef type class that abstracts over the details of manipulating references, allowing one to write code that can operate in either the ST monad or the IO monad.

This package is a compatibility package for a singleton data type . > data Solo a = Solo a . Note: it's not a @newtype@ . @Solo@ is available in @base-4.16@ (GHC-9.2).

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

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 Haskell package was originally present in classy-prelude.

This package provides a simple type class for converting values of different string types into values of other string types.

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

A UTF8 layer for Strings. The utf8-string package provides operations for encoding UTF8 strings to Word8 lists and back, and for reading and writing UTF8 without truncation.

This package provides a writer monad for multi-line string literals.

This package provides extensible exceptions for both new and old versions of GHC (i.e., < 6.10).
