Functional-Programming
Functional Programming concepts, examples and patterns
This repository is a tutorial collection showcasing functional programming concepts across multiple languages (Haskell, OCaml, Scala, Scheme, Clojure, Python). It provides reusable code snippets, examples, and case studies to illustrate FP ideas in a comparative manner. The purpose of this tutorial is to illustrate functional programming concepts in many languages by providing reusable and useful snippets of code, examples, case studies and applications. The project’s web site was updated and improved with a table of contents on side-bar. In addition, the new layout makes reading easier to read and browse the content. Those pages in the theme are in the gh-pages branch which can easy be downloaded for offline usage. -

GHC (Glasgow Haskell Compiler)
Mirror of the Glasgow Haskell Compiler
GHC (Glasgow Haskell Compiler) is the leading open-source compiler and interactive environment for the Haskell programming language, supporting the Haskell 2010 standard plus numerous language extensions. It compiles to native machine code (via LLVM or C), and includes the interactive GHCi REPL. For full information on building GHC, see the GHC Building Guide. Here follows a summary - if you get into trouble, the Building Guide has all the answers. For building library documentation, you'll need Haddock. To build the compiler documentation, you need Sphinx and Xelatex (only for PDF output). -

GHCJS
Haskell to JavaScript compiler, based on GHC
GHCJS is a Haskell-to-JavaScript compiler that reuses GHC’s front end to compile Haskell source into JavaScript for execution in browsers and Node.js. It aims to preserve Haskell’s semantics—including laziness and rich types—by shipping a small runtime and shims for core libraries. Developers write normal Haskell, use Cabal/Stack to build, then bundle the generated JavaScript alongside required support code. Interoperability with the JavaScript world is provided through a foreign-function interface, allowing Haskell code to call browser APIs or Node modules and to be called back from JS. The ecosystem includes packages tailored to GHCJS (for example DOM bindings and FRP libraries), enabling full single-page apps written in Haskell. Because it mirrors GHC closely, many pure Haskell libraries “just work,” making it practical to share code between server and client. -

GHCid
Very low feature GHCi based IDE
ghcid is a minimalist development tool for Haskell that runs GHCi as a daemon, watches source files for changes, reloads automatically, and shows compile errors instantly—providing a tight edit-feedback loop. In general, to use ghcid, you first need to get ghci working well for you. In particular, craft a command line or .ghci file such that when you start ghci it has loaded all the files you care about (check :show modules). If you want to use --test check that whatever expression you want to use works in that ghci session. Getting ghci started properly is one of the hardest things of using ghcid, and while ghcid has a lot of defaults for common cases, it doesn't always work out of the box. Expressions that read from standard input are likely to hang, given that Ghcid already uses the standard input to interact with Ghci. -

Gitit
A wiki using HAppS, pandoc, and git
Gitit is a wiki application written in Haskell that uses Happstack for serving and Pandoc for markup conversion. Wiki content and attachments are stored in Git, Darcs, or Mercurial repositories, allowing versioning via VCS or web editing. To run gitit, you'll need git in your system path. (Or darcs or hg, if you're using darcs or mercurial to store the wiki data.) Gitit assumes that the page files (stored in the git repository) are encoded as UTF-8. Even page names may be UTF-8 if the file system supports this. So you should make sure that you are using a UTF-8 locale when running gitit. (To check this, type locale.) The metadata block consists of a list of key-value pairs, each on a separate line. If needed, the value can be continued on one or more additional line, which must begin with a space. -

HLint
Haskell source code suggestions
HLint is a linter for Haskell that suggests stylistic improvements and potential simplifications in Haskell code. It parses Haskell source files and provides hints to refactor code for better readability, maintainability, or performance. HLint is highly configurable and supports custom rules, integrations with CI tools, and editor plugins. It is widely used in the Haskell ecosystem for maintaining consistent code standards. -

HaLVM
The Haskell Lightweight Virtual Machine (HaLVM)
HaLVM is a Haskell-based unikernel system that lets you write entire virtual machines in Haskell and run them directly on a hypervisor, traditionally Xen. Instead of deploying a full operating system, you compile a Haskell program into a tiny image that boots as its own VM, which reduces the attack surface and startup time. The project adapts GHC and the Haskell runtime to a minimal environment, providing the I/O, networking, and memory facilities necessary for standalone services. Its design encourages highly isolated services—each VM does one job—making it attractive for security-sensitive components and research on microservice-style architectures. Developers get to keep Haskell’s strong typing, concurrency abstractions, and functional style while targeting bare virtual hardware. Although device support is intentionally narrow compared to general-purpose OSes, the trade-off is predictability and very small, auditable deployments. -

Hakyll
A static website compiler library in Haskell
Hakyll is a Haskell library for building static websites. It uses a highly configurable domain-specific language (DSL) embedded in Haskell, enabling users to define content compilation pipelines in code. It’s ideal for blogs and small-to-medium websites, with support for Markdown, Pandoc, and syntax highlighting. Hakyll is a static site generator library in Haskell. More information (including a tutorial) can be found on the Hakyll homepage. You can install this library using cabal. If Stack fails, please see which Stackage snapshots contain Hakyll and specify one explicitly. -

Haskell Dockerfile Linter
Dockerfile linter, validate inline bash, written in Haskell
A smarter Dockerfile linter that helps you build best practice Docker images. The linter parses the Dockerfile into an AST and performs rules on top of the AST. It stands on the shoulders of ShellCheck to lint the Bash code inside RUN instructions. You can run hadolint locally to lint your Dockerfile. You can download prebuilt binaries for OSX, Windows and Linux from the latest release page. However, if this does not work for you, please fall back to container (Docker), brew or source installation. Configuration files can be used globally or per project. -

Haskell IDE Engine (HIE)
The engine for haskell ide-integration. Not an IDE
This project aims to be the universal interface to a growing number of Haskell tools, providing a fully-featured Language Server Protocol server for editors and IDEs that require Haskell-specific functionality. Supports plain GHC projects, cabal projects(sandboxed and non sandboxed) and stack projects. Fast due to caching of compile info. Uses LSP, so should be easy to integrate with a wide selection of editors. Diagnostics via hlint and GHC warnings/errors. Code actions and quick fixes via apply-refact. Type information and documentation(via haddock) on hover. Jump to definition. -

Haxl
Haskell library that simplifies access to remote data
Haxl is a Haskell library that simplifies access to remote data, such as databases or web-based services. Haxl can automatically batch multiple requests to the same data source, request data from multiple data sources concurrently, cache previous requests, and memoize computations. Having all this handled for you behind the scenes means that your data-fetching code can be much cleaner and clearer than it would otherwise be if it had to worry about optimizing data-fetching. To use Haxl in your own application, you will likely need to build one or more data sources: the thin layer between Haxl and the data that you want to fetch, be it a database, a web API, a cloud service, or whatever. There is a generic datasource in "Haxl.DataSource.ConcurrentIO" that can be used for performing arbitrary IO operations concurrently, given a bit of boilerplate to define the IO operations you want to perform.
