A collection of machine-checkend mathematical proofs
The Archive of Formal Proofs is a collection of proof libraries, examples, and larger scientifc developments, mechanically checked in the theorem prover Isabelle. It is organized in the way of a scientific journal. Submissions are refereed.
The Eta Programming Language, a dialect of Haskell on the JVM
...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.
We extend the Eclipse IDE with tools for development in Haskell, a functional programming language, providing support for a wide range of tools (compilers, interpreters, doc tools etc.) in a coherent, convenient and configurable environment.
foundation of the General Intelligence Operating System
HSPL is Human Speakable Programming Language, allowing for communication between human-to-computer and human-to-human in the same language.
This project has moved to http://sourceforge.net/p/spel
We are currently working on human-to-computer programming-language with mostly English base vocabulary.
Though once we have that, we plan to add support for other world Languages, including Chinese, Spanish, Russian, Arabic, Hindi, among others.
Eventually HSPL shall be the...
Paessler: Easy to Use With Enterprise Power. Free Trial
A low-code dashboard makes monitoring intuitive for any admin, while scripting and custom sensors give experts full control.
You shouldn't have to choose between a monitoring tool that's easy to use and one that's powerful enough for a complex environment. PRTG's low-code interface lets any admin build dashboards, set alerts and monitor devices without scripting, while custom sensors and full API access are there when your team needs deeper control. One platform, no compromise. Download a free 30-day trial now.
wikit is another wiki engine suited for small teams. It’s written in Haskell with using Yesod Web Framework. It’s cross platform and was designed to be running as a desktop service application servicing wiki articles and providing some basic capabilities in terms of searching and storing data.
It’s perhaps most distinct feature is that it relies on backing Git distributed source control system. And keeps it’s articles in markdown format. Which makes it very easy to port out of the wiki...
Xcerpt is a Query and Transformation Language for XML and Semistructured data. Instead of the navigational approach of XPath-based languages like XSLT or XQuery, Xcerpt uses patterns for querying and is based on concepts of logic programming like unifica
An R5RS Scheme interpreter and library written in Haskell. Provides advanced features including continuations, hygienic macros, and the full numeric tower.
Can you recover when it matters most? Take this quick assessment to identify gaps and build greater recovery confidence.
Is your recovery strategy as strong as you think? Take this quick self-assessment to check your recovery readiness and gain tailored insights. In only 2 minutes, you'll learn where you fall on the recovery readiness scale.
MUgen is an emulator generator which works in a way similar to yacc. It takes an input machine description and outputs a source file which is a fully implemented emulator of that system. This is the open-source system.
This is the extended euclidean algorithm implemented in haskell.
It will put every single step of the algorithm in a file and show the actual result and everything in between.
Fusion is a powerful high level programming language that merges several feature from Ruby, Python, Java, C++, Visual Basic, etc, in a only language. It's implemented by means of a compiler written in Haskell that generates Ruby code.
A wrapper around Gtk+ 2.x for the functional language Haskell featuring full memory management, Unicode awareness and of course the new features of Gtk2.
Agda is a system for incrementally developing proofs and programs. This is the sourceforge project for the PREVIOUS Agda (Agda 1). A newer version of Agda (Agda 2) in beta testing is available from: http://wiki.portal.chalmers.se/agda/
More Than Parsing is a parser generator for context free grammars defined in a BNF-like format. It generates scanners, parsers, ASTs, etc. This sf project is no longer active, development will continue in a different place.
Functional Networked Integrated Environment (FUNNIE) is a networked CSCW programming environment specifically tuned to the needs of students and instructors, based on a subset of Haskell.
JHaskell provides a Haskell interpreter and compiler for the JVM. The goal is to make Haskell a viable language for development for the Java platform and also to allow existing Haskell programs to run on the JVM.
A set of MediaWiki extensions and other tools developed for the Twelf wiki (http://twelf.plparty.org) that enable a wiki to naturally incorporate logic Twelf in a number of meaningful and useful ways.
A command line tool that allows a semi-automated scientific articles management. It assumes an existence of a directory of a specific format in the file system. The tool interprets the data stored in the directory (called a repository), extend it via the usage of some automatic tools such as pdftotext, and search the text as well as some metadata.
