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

The ghc-lib-parser-ex package contains GHC API parse tree utilities.

This library provides finger trees, a general sequence representation with arbitrary annotations, for use as a base for implementations of various collection types. It includes examples, as described in section 4 of Ralf Hinze and Ross Paterson, "Finger trees: a simple general-purpose data structure".

This package provides the ShortText type which is suitable for keeping many short strings in memory. This is similar to how ShortByteString relates to ByteString.

The main difference between Text and ShortText is that ShortText uses UTF-8 instead of UTF-16 internally and also doesn't support zero-copy slicing (thereby saving 2 words). Consequently, the memory footprint of a (boxed) ShortText value is 4 words (2 words when unboxed) plus the length of the UTF-8 encoded payload.

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.

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.

With this package you can build a Storable instance of a record type from Storable instances of its elements in an elegant way. It does not do any magic, just a bit arithmetic to compute the right offsets, that would be otherwise done manually or by a preprocessor like C2HS. There is no guarantee that the generated memory layout is compatible with that of a corresponding C struct. However, the module generates the smallest layout that is possible with respect to the alignment of the record elements.

This Haskell package provides some useful control operators for looping.

Haskellers are usually familiar with monoids and semigroups. A monoid has an appending operation <> (or mappend), and an identity element, mempty. A semigroup has an appending <> operation, but does not require a mempty element. A Semiring has two appending operations, plus and times, and two respective identity elements, zero and one. More formally, a Semiring R is a set equipped with two binary relations + and *, such that: (R,+) is a commutative monoid with identity element 0, (R,*) is a monoid with identity element 1, (*) left and right distributes over addition, and . multiplication by 0 annihilates R.

This package makes it possible to define schemas for use when loading configuration files using the config-value format. These schemas can be used to process a configuration file into a Haskell value or to automatically generate documentation for the file format.

Type classes for convenient marshalling and calling of Lua functions.

This package provides a library to parse and render YAML documents.

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

This package provides an implementation of n-ary sums and n-ary products. The module Data.SOP is the main module of this library and contains more detailed documentation. The main use case of this package is to serve as the core of generics-sop.

This library provides a utility function liftType, which accepts a type application argument and returns the Template Haskell Type representation of it.

This Haskell package provides a family of type-safe templates with simple variable interpolation. Shakespeare templates can be used inline with a quasi-quoter or in an external file and it interpolates variables according to the type being inserted.

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.

Async provides a library to run IO operations asynchronously, and wait for their results. It is a higher-level interface over threads in Haskell, in which Async a is a concurrent thread that will eventually deliver a value of type a.

This library provides various semigroups, specialized containers and a general map/reduce framework for Haskell.

This Haskell library provides a Template Haskell deriver for unboxed vectors, given a pair of coercion functions to and from some existing type with an Unbox instance.

This package provides functions to prevent or capture writing to stdout and other handles.

This package provides tools to measure the memory usage of a Haskell value or function.

This package defines a class, Hashable, for types that can be converted to a hash value. This class exists for the benefit of hashing-based data structures. The package provides instances for basic types and a way to combine hash values.

This package provides a pure interface for compressing and decompressing LZMA streams of data represented as lazy ByteStrings. A monadic incremental interface is provided as well.
