    Agda

    Agda

    Agda is a dependently typed programming language

    Agda is a dependently typed, total functional programming language and interactive theorem prover based on Martin-Löf’s type theory. It allows expressing programs and proofs in the same language, using the Curry–Howard correspondence. It features interactive development via Emacs, Atom, or VS Code. Agda is a dependently typed functional programming language. It has inductive families, i.e., data types which depend on values, such as the type of vectors of a given length. It also has parametrised modules, mixfix operators, Unicode characters, and an interactive Emacs interface which can assist the programmer in writing the program. Agda is a proof assistant. It is an interactive system for writing and checking proofs. Agda is based on intuitionistic type theory, a foundational system for constructive mathematics developed by the Swedish logician Per Martin-Löf. It has many similarities with other proof assistants based on dependent types, such as Coq, Epigram, Matita and NuPRL.

    ShellCheck

    ShellCheck

    A static analysis tool for shell scripts

    ShellCheck is a GPLv3 tool that provides warnings and possible suggestions for bash/sh shell scripts. ShellCheck finds bugs in your shell scripts. You can cabal, apt, dnf, pkg or brew install it locally right now. ShellCheck highlights and clarifies typical beginner's syntax mistakes and issues that cause a shell to give a cryptic error message. It shows typical intermediate level semantic problems that cause a shell to behave in a abnormally and counter-intuitively. It can also discover ssubtle caveats, corner cases and pitfalls that may cause an user's working script to fail under probable future circumstances. ShellCheck.net is always synchronized to the latest git version, and is the simplest way to give ShellCheck a go.

    The Aura Package Manager

    The Aura Package Manager

    A secure, multilingual package manager for Arch Linux

    Aura, a secure, multilingual package manager for Arch Linux. Aura's original purpose is as an AUR helper, in that it automates the process of installing packages from the Arch User Repositories. It is, however, capable of much more. Aura is a package manager for Arch Linux. Its original purpose is as an AUR helper, in that it automates the process of installing packages from the Arch User Repositories. It is, however, capable of much more. Aura doesn't just mimic pacman; it is pacman. All pacman operations and their sub-options are allowed. Some even hold special meaning in Aura as well. -S yields pacman packages and only pacman packages. This agrees with the above. In Aura, the -A operation is introduced for obtaining AUR packages. -A comes with sub-options you're used to (-u, -s, -i, etc.). PKGBUILDs from the AUR can contain anything. It's a user's responsibility to verify the contents of a PKGBUILD before building, but people can make mistakes and overlook details.

    Cabal

    Cabal

    Upstream development repository for Cabal and cabal-install

    Cabal is a system for building and packaging Haskell libraries and programs. It defines a common interface for package authors and distributors to easily build their applications in a portable way. Cabal is part of a larger infrastructure for distributing, organizing, and cataloging Haskell libraries and programs. The term cabal can refer to either: cabal-the-spec (.cabal files), cabal-the-library (code that understands .cabal files), or cabal-the-tool (the cabal-install package which provides the cabal executable); usually folks are referring to cabal-the-tool when they say cabal. To install the cabal executable you can use ghcup (if you're using Linux), the Haskell Platform, install the cabal-install package from your distributions package manager (if using Linux or Mac), or download the source or prebuilt binary from the Download page.

    BSC

    BSC

    Bluespec Compiler (BSC)

    BSC is the open source compiler toolchain for Bluespec SystemVerilog, a high-level, rule-based hardware design language. It translates Bluespec descriptions into synthesizable Verilog, letting developers bring typed, modular abstractions into mainstream FPGA/ASIC flows. The compiler performs scheduling of atomic rules, elaborates parameterized modules, and enforces interface contracts, producing predictable RTL that integrates with existing EDA tools. A companion simulator enables fast functional execution and debugging before handing designs to traditional verification and synthesis stages. The ecosystem includes standard libraries, FIFOs, interfaces, and utilities that encourage reuse and clean separation of datapaths and control. By raising the abstraction for hardware architecture while preserving efficient output, BSC helps teams explore complex designs—such as RISC-V cores or accelerators—more productively.

    Clash

    Clash

    Haskell to VHDL/Verilog/SystemVerilog compiler

    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.

    Unison

    Unison

    A friendly programming language from the future

    Unison is an open source functional programming language based on a simple idea with big implications: code is content-addressed and immutable. Unison’s core idea is that code is immutable and identified by its content. This lets us reimagine many aspects of how a programming language works. We simplify codebase management, Unison has no builds, no dependency conflicts, and renaming things is trivial. The same core idea forms the basis for a runtime that robustly supports dynamic code deployment, allowing a single Unison program to describe entire elastic distributed systems. Though a lot of the work on Unison is still experimental and ongoing, we’re sharing an early alpha release of the language for you to test out. We’ll make a more finished release generally available soon. In the meantime, anyone is welcome to help with alpha testing.

    Unused

    Unused

    A command line tool to identify unused code

    Unused identifies unused code in Rails, Phoenix, and other types of applications, improving developer productivity. By default, unused leverages a different memory allocator called mimalloc. For my local benchmarks, it speeds up execution by a significant amount (which is documented in the commit introducing mimalloc), but currently runs into sporadic issues on Apple M1 devices. If you run into issues with segmentation faults, consider reinstalling unused with the stock Rust allocator. It is strongly recommended you install Universal Ctags to generate tags files. Universal Ctags supports more languages and has native parsers for a good number of them, resulting in faster tags generation time.

    Wasp

    Wasp

    A programming language that understands what a web app is

    Wasp (Web Application Specification Language) is a declarative DSL (domain-specific language) for developing, building and deploying modern full-stack web apps with less code. Concepts such as app, page, user, login, frontend, production, etc. are baked into the language, bringing a new level of expressiveness and allowing you to get more work done with fewer lines of code. While describing high-level features with Wasp, you still write the rest of your logic in your favorite technologies (currently React, NodeJS, Prisma). Wasp is in alpha and is therefore likely to change a lot, have bugs and miss important features. Due to its expressiveness, you can create and deploy a production-ready web app from scratch with very few lines of concise, consistent, declarative code. When you need more control than Wasp offers, you can write code in existing technologies such as js/html/css/... and combine it with Wasp code!

    Echidna

    Echidna

    Ethereum smart contract fuzzer

    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.

    Nix Output Monitor

    Nix Output Monitor

    Pipe your nix-build output through the nix-output-monitor

    nix-output-monitor (also known as nom) is a workflow tool that enhances the readability and usability of nix-build output by providing pretty, parsed summaries and highlighting important events during Nix builds. This was an experiment to write something fun and useful in Haskell, which proved to be useful to quite a lot of people. By now, nom is quite fully featured with support for nix v1 commands (e.g. nix-build) and nix v2 commands (e.g. nix build). At this point it seems like I will maintain nom until better UX options for nix arrive. Every entry in the nom tree stands for one derivation. No build will be printed twice in the tree, it will only be shown for the lowermost dependency. Use the colors from above to read the summary.

    Obelisk

    Functional reactive web and mobile applications, with batteries

    Functional reactive web and mobile applications, with batteries included. Obelisk's goal is to represent a cohesive, highly-curated set of choices that Obsidian Systems has made for building these types of applications in a way that is extremely fast but does not compromise on production readiness. Obelisk allows you to build high-quality web and mobile applications very quickly using Reflex. In minutes you can go from an empty directory to an interactive application that works on web, iOS, and Android, all sharing the same Haskell codebase! Obelisk's development environment also enables extremely rapid development and feedback. You can take advantage of Haskell's type system across the frontend and backend boundary. This means changes to your backend that would break your frontend are immediately detected during development and vice versa. Obelisk uses Haskell's compiler to give you a complete "TODO list" of what needs to be updated.

    Reflex Platform is a curated package set and set of tools that let you build Haskell packages so they can run on a variety of platforms. Reflex Platform is built on top of the nix package manager. The core packages in Reflex Platform are known to work together and are tested together. the core packages in Reflex Platform are cached so you can download prebuilt binaries from the public cache instead of building from scratch. Nix locks down dependencies even outside the Haskell ecosystem (e.g., versions of C libraries that the Haskell code depends on), so you get completely reproducible builds. Reflex Platform is designed to target iOS and Android on mobile, JavaScript on the web, and Linux and macOS on desktop. It's Haskell, everywhere. Reflex Platform comes packaged with tools to make development easier, like a hoogle server that you can run locally to look up definitions.

    Rome

    Rome

    Carthage cache for S3, Minio, Ceph, Google Storage, Artifactory, etc.

    Carthage cache for S3, Minio, Ceph, Google Storage, Artifactory and many others. Rome is a tool that allows developers on Apple platforms to use Amazon's S3, Minio, Ceph, other S3-compatible object stores or/and a local folder. The Rome binary is also attached as a zip to each release on the releases page here on GitHub. Suppose you're working a number of frameworks for your project and want to share those with your team. A great way to do so is to use Carthage and have team members point the Cartfile to the new framework version (or branch, tag, commit) and run Carthage update. Unfortunately, this will require them to build from scratch a new framework. This is particularly annoying if the dependency tree for that framework is big and/or takes a long time to build. Use a cache. The first team member (or a CI) can build the framework and share it, while all other developers can get it from the cache with no waiting time.

    Semantic

    Semantic

    Parsing, analyzing, and comparing source code across many languages

    semantic is a Haskell library and command line tool for parsing, analyzing, and comparing source code. Run semantic --help for complete list of up-to-date options. Semantic uses tree-sitter to generate parse trees, but layers in a more generalized notion of syntax terms across all supported programming languages. We'll see why this is important when we get to diffs and program analysis, but for now let's just inspect some output. It helps to have a simple program to parse. Symbols are named identifiers driven by the ASTs. This is the format that github.com uses to generate code navigation information allowing c-tags style lookup of symbolic names for fast, incremental navigation in all the supported languages. The incremental part is important because files change often so we want to be able to parse just what's changed and not have to analyze the entire project again.
