Clash is a functional hardware description language that borrows both its syntax and semantics from the functional programming language Haskell. It provides a familiar structural design approach to both combinational and synchronous sequential circuits. The Clash compiler transforms these high-level descriptions to low-level synthesizable VHDL, Verilog, or SystemVerilog. Clash is an open-source project, licensed under the permissive BSD2 license, and actively maintained by QBayLogic. The Clash project is a Haskell Foundation affiliated project. Clash is built on Haskell which provides an excellent foundation for well-typed code. Together with Clash's standard library it is easy to build scalable and reusable hardware designs. Load your designs in an interpreter and easily test all your component without needing to setup a test bench. Although Clash offers many features, you sometimes need to directly access VHDL, Verilog, or SystemVerilog directly.

Corrode is an experimental translator that converts C code into Rust, intended to help migrate existing C codebases toward safer Rust idioms. It parses C, maps C types and constructs into Rust equivalents, and generates code that compiles under rustc, introducing unsafe only when necessary. The tool seeks to produce readable Rust that a developer can then refine by hand, rather than a perfect one-to-one mechanical translation. It handles common C features such as pointers, structs, enums, arrays, and function calls, while flagging areas that need attention during the migration. Preprocessor handling and tricky macro patterns are approached pragmatically, aiming for working output over exhaustive transformation. As a proof-of-concept, it demonstrates how automated tooling can accelerate moving from legacy C to a memory-safe language without a full rewrite.

A pretty sweet 4px wide pixel font. I never found the pixel font that was perfect for me, so I decided to roll my own with creep. It is a pretty compact (only 4px wide!) font that's great for smaller screens (like my 11" laptop). I'm constantly adding in new characters (diacritics, box-drawing characters, etc.), so I figured I'd put it up on GitHub for people to reap benefits of this. I also recently added some nice Haskell features (that can be used in other languages too)! Creep has most of the basic box drawing characters implemented. Therefore creep usually works with most ncurses-type programs or with tmux window-splitting for example. Creep supports all the symbols needed for Lokaltog's awesome powerline plugin for vim. Creep has the necessary symbols for creating sparklines. This is cool for tools like rainbarf and others. I've added support for a better-looking Haskell syntax. Take a look at the Haskell wiki page to get an idea of how it looks and how to use it in vim.

A programming language designed for searching and manipulating tree-structured data, particularly corpora of natural languages encoded in an s-expression-like format.

Cryptol is a domain-specific language (DSL) for specifying and verifying cryptographic algorithms. Developed by Galois, Cryptol provides a high-level mathematical syntax for describing cryptographic primitives and enables formal verification of algorithm properties. It is used in academic, research, and defense sectors to validate correctness and security through symbolic execution and model checking, ensuring critical cryptographic code is free of design flaws.

A cross-platform unit testing framework for C++.

Dickinson is a text-generation language. You can try out the language on the web without installing anything. Binaries for some platforms are available on the releases page. There is an install script that will try to download the right release for your computer.

The Dolphin Project is intended to be a research project aggregating tools related to Open Source Satisfiability Solver tools and tools related to them like Bounded Model Checkers and Software Verifiers.

Prototype to examine techniques of generating web services at run-time (not compile time) from a static service description.

Echidna is a weird creature that eats bugs and is highly electrosensitive (with apologies to Jacob Stanley) More seriously, Echidna is a Haskell program designed for fuzzing/property-based testing of Ethereum smarts contracts. It uses sophisticated grammar-based fuzzing campaigns based on a contract ABI to falsify user-defined predicates or Solidity assertions. We designed Echidna with modularity in mind, so it can be easily extended to include new mutations or test specific contracts in specific cases. Optional corpus collection, mutation and coverage guidance to find deeper bugs. Powered by Slither to extract useful information before the fuzzing campaign. Source code integration to identify which lines are covered after the fuzzing campaign. Curses-based retro UI, text-only or JSON output.

ElixirFM is a high-level implementation of Functional Arabic Morphology. The core of ElixirFM is written in Haskell, while interfaces in Python and Perl support lexicon editing and other interactions. http://github.com/otakar-smrz/elixir-fm

Encode Arabic provides tools for encoding and decoding Arabic in Haskell, Python, Perl, or LaTeX. Interprets the ArabTeX notation to generate original orthography or phonetic transcription. Supports Buckwalter and other romanizations. Converts legacy byte encodings into Unicode. http://github.com/otakar-smrz/encode-arabic

A powerful programming language to build concurrent & distributed systems on the JVM. Eta is a pure, lazy, strongly typed functional programming language on the JVM. It brings two big ecosystems, the JVM and Haskell, together. This allows you to harness the best of both ecosystems to build your applications quickly and effectively. Eta's concurrency support helps you to build highly scalable systems. Eta has a strongly-typed Foreign Function Interface (FFI) that allows you to safely interoperate with Java. Eta has global type inference, giving you a dynamic language experience, but with a strong typing hidden underneath. Eta offers a wide range of strategies for handling concurrency including Software Transaction Memory (STM), MVars, and Fibers. Using the powerful and type-safe Servant web framework, we define our API as a type and the handler types for each endpoint are automatically generated and conversions happen automatically.

Eve is intended to be a Haskell-derived language with more familiar (Python/Rubyish) syntax. Short term, think of it as a gateway drug to Haskell for Python/Ruby programmers. Long-term, it's intended to be a practical (DB/webapp/GUI-enabled) Haskell.

Here we have fun developing software related to embedded extension languages and small languages in many application domains, using existing languages and/or creating new ones.

Extism is a plug-in system for everyone. We've carefully designed it to be flexible, fitting into codebases of all shapes and sizes, but opinionated enough so that things Just Work™ the way they should. Extism's goal is to make all software programmable. You can use Extism in your codebase, regardless of the programming language. We support several environments through our official Host SDKs, and are adding more language support all the time. A plug-in system is software that enables your users or customers to add some logic into certain points in your application. You decide where this logic runs, and your users decide what the plug-in does. Many engineering teams face an ever-growing list of feature requests, often exceeding their bandwidth several times over. How can you ever keep up? Making your product extensible by its end-users is a great way to move some of those features outside the core, and empower customers to make your software more useful for them.

Fay is a compiler for a proper subset of Haskell that type-checks using GHC and compiles to JavaScript. It supports pure functional programming, a Fay-specific monad, FFI, optional tail-call optimization, and integration with Cabal packages. GHC-compatible type checking, ensuring correctness. Lazy, pure functional semantics with a distinct Fay monad. Foreign Function Interface (FFI) to integrate native JS code. Compatible with standard Haskell packaging tools like Cabal.

Seamlessly deploy websites and store secure user data. Fission is built inside of a pure Nix shell via the Stack integration. This means that you should only need to type stack build to do a complete build of all packages. If you're using a nix shell, you can use cachix to prevent re-building dependencies.

The Fluxion framework is a prototype data integration system using Semantic Web technologies.
