This package provides a backend for the ghc-persistent library using the ghc-postgresql-simple package.

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>.

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

This package provides a modular backend for rendering diagrams created with the diagrams embedded domain-specific language (EDSL) to Scalable Vector Graphics (SVG) files.

This library provides parsers and printers for bencoded data. Bencode is the encoding used by the peer-to-peer file sharing system BitTorrent for storing and transmitting loosely structured data.

cassava is a library for parsing and encoding RFC 4180 compliant comma-separated values (CSV) data, which is a textual line-oriented format commonly used for exchanging tabular data.

cassava's API includes support for:

• Index-based record-conversion

• Name-based record-conversion

• Typeclass directed conversion of fields and records

• Built-in field-conversion instances for standard types

• Customizable record-conversion instance derivation via GHC generics

• Low-level bytestring builders (see Data.Csv.Builder)

• Incremental decoding and encoding API (see Data.Csv.Incremental)

• Streaming API for constant-space decoding (see Data.Csv.Streaming)

Moreover, this library is designed to be easy to use; for instance, here's a very simple example of encoding CSV data:

>>> Data.Csv.encode [("John",27),("Jane",28)]
"John,27
Jane,28
"

Concatenative gives Haskell Factor-style combinators and arrows for postfix notation. For more information on stack based languages, see https://concatenative.org.

This Haskell package uses a monad transformer approach for logging.

This package provides Template Haskell functions for determining source code locations of messages.

This package provides a library for generating 2D charts and plots, with backends provided by the Cairo and Diagrams libraries.

This package provides types and combinators for linear algebra on free vector spaces.

Various tasty helpers and utilities to test HsLua oparations. Built on top of tasty-hunit.

This Haskell package provides an API for constructing vectors. It provides the composable Builder abstraction, which has instances of the Monoid and Semigroup classes.

You would first use the Builder abstraction to specify the structure of the vector; then you can execute the builder to actually produce the vector.

Skylighting is a syntax highlighting library with support for over one hundred languages. It derives its tokenizers from XML syntax definitions used by KDE's KSyntaxHighlighting framework, so any syntax supported by that framework can be added. An optional command-line program is provided. Skylighting is intended to be the successor to highlighting-kate. This package provides generated syntax modules based on the KDE XML definitions provided by the skylighting-core package.

This package provides a compatibility layer for using GHC call stacks with different versions of the compiler.

This module allows tokens produced by skylighting-core to be rendered as ConTeXt commands.

This package provides a full-featured binding to the C libmagic library. With it, you can determine the type of a file by examining its contents rather than its name.

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.

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 helper functions for working with haskell-src-exts trees.

This Haskell library provides a place for lots of orphan instances for the ghc-vector package.

This package defines a Language.Haskell.TH.Syntax.Compat module, which backports the Quote and Code types to work across a wide range of template-haskell versions. On recent versions of template-haskell (2.17.0.0 or later), this module simply re-exports Quote and Code from Language.Haskell.TH.Syntax.

Haddock is a documentation-generation tool for Haskell libraries. These modules expose some functionality of it without pulling in the GHC dependency. Please note that the API is likely to change so specify upper bounds in your project if you can't release often. For interacting with Haddock itself, see the ‘haddock’ package.

This Haskell package provides additional data structures, and other added capabilities layered on top of the Par monad.

Utilities for dealing with IEEE floating point numbers, ported from the Tango math library; approximate and exact equality comparisons for general types.
