Agda is a dependently typed functional programming language: it has inductive families, which are similar to Haskell's GADTs, but they can be indexed by values and not just types. It also has parameterised modules, mixfix operators, Unicode characters, and an interactive Emacs interface (the type checker can assist in the development of your code). Agda is also 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 and NuPRL.

This Emacs mode enables interactive development with Agda. It also aids the input of Unicode characters.

SQIR is a Small Quantum Intermediate Representation for quantum programs. Its intended use is as an intermediate representation in a Verified Optimizer for Quantum Circuits (VOQC), but we have also used it to implement verified versions of several quantum algorithms.

QuantumLib is a Coq library for verifying the ZX Calculus.

This development encodes category theory in Coq, with the primary aim being to allow representation and manipulation of categorical terms, as well realization of those terms in various target categories.

This package provides a collection of theories and plugins that may be useful in other Coq developments.

inQWIRE's QuantumLib is a Coq library for reasoning about quantum computation and quantum programs.

Emacs major mode for working with egglog (e-graphs, EqSat + Datalog).

Emacs major-mode for editing GAP files.

Emacs major mode for editing Agda code embedded in Org (.lagda.org) files

Provides font-lock, REPL integration ( via comint ) and a basic help documentation for the J programming language.

This package provides a completion system for mathematical symbols.

This package provides an org babel mode for evaluating blocks of egglog code in org mode.

Snac is a simple, minimalistic ActivityPub instance written in portable C.

It features:

• Lightweight, minimal dependencies

• Extensive support of ActivityPub operations, e.g. write public notes, follow users, be followed, reply to the notes of others, admire wonderful content (like or boost), write private messages, etc.

• Multiuser support

• Mastodon API support, so Mastodon-compatible apps can be used

• Simple but effective web interface

• Easily-accessed MUTE button to silence users

• Tested interoperability with related software

• No database needed

• Totally JavaScript-free; no cookies either

PolyGlot is a "UCI adapter". It connects a UCI chess engine to an xboard interface.

PolyGlot tries to solve known problems with other adapters. For instance, it detects and reports draws by fifty-move rule, repetition, etc...

Speed Dreams is a car racing simulator featuring high-quality 3D graphics and an accurate physics engine, aiming for maximum realism. Initially forked from TORCS, it features improvements to the graphics and physics simulation, and supports modern input methods such as gamepads by use of the SDL library. It features more than 20 tracks and more than 80 cars to race with. Extra (freely licensed) assets can be downloaded via the in-game download manager.

QVGE is a multiplatform graph editor written in C++/Qt. Its main goal is to make possible visually edit two-dimensional graphs in a simple and intuitive way.

Context Free is a program that generates images from written instructions called a grammar. The program follows the instructions in a few seconds to create images that can contain millions of shapes.

A flexible Haskell implementation of minimum, maximum, minimum-priority, maximum-priority and custom-ordered heaps.

Lazy SmallCheck is a library for exhaustive, demand-driven testing of Haskell programs. It is based on the idea that if a property holds for a partially-defined input then it must also hold for all fully-defined refinements of the that input. Compared to eager input generation as in SmallCheck,Lazy SmallCheck may require significantly fewer test-cases to verify a property for all inputs up to a given depth.

This package implements functions, analogous to those from Data.List, to create and manipulate infinite lists: data Stream a = Cons a (Stream a). It provides alternative definitions for those Prelude functions that make sense for such streams. Note that this package has (almost) nothing to do with the work on Stream Fusion by Duncan Coutts, Roman Leshchinskiy, and Don Stewart.

ThreadScope is a graphical viewer for thread profile information generated by the Glasgow Haskell compiler (GHC).

The Threadscope program allows us to debug the parallel performance of Haskell programs. Using Threadscope we can check to see that work is well balanced across the available processors and spot performance issues relating to garbage collection or poor load balancing.

This is the core library of the Gtk2Hs suite of libraries for Haskell based on Gtk+. Gtk+ is an extensive and mature multi-platform toolkit for creating graphical user interfaces.
