Open Source Eiffel Software

EiffelStudio is an Integrated Development Environment (IDE) that provides comprehensive facilities to programmers. It offers a comprehensive suite of tools that enable programmers to produce correct, reliable, and maintainable software while keeping control of the development process. If you want to create fast, robust, scalable applications, then EiffelStudio™ will offer you a cost-effective solution. Imagine being able to model your system as you think – capturing your requirements and your thought processes with EiffelStudio. When ready to design, you build upon the model you just created, still with EiffelStudio. Then you implement with EiffelStudio. You never need to throw anything out and start over. You don’t need extra tools to go back and safely make changes in your architecture. Roundtrip engineering? It’s built in by design. Testing, metrics and productivity tools? They’re built in. EiffelStudio accommodates quickly and efficiently new thoughts and changes.

FOX is an Extensible C++ Class Library for Multi-Platform GUI development. Platforms supported include Linux, Windows NT/9x/2K, and UNIX/X11 workstations (IRIX, Solaris, HP-UX, Tru64, AIX, FreeBSD, and others).

The Gobo Eiffel Project provides the Eiffel community with free and portable Eiffel tools and libraries.

MERMAID is an object-oriented domain modeling tool to create enterprise models using an UML class diagram, an object-event table and finite state machines. The CASE tool checks view consistency, has XMI support and code generation abilities.

Exploring the possibilities of doing an Operating System completely different than all of the existing ones. Instead of basing it upon concepts that are 40 years old, design it from the ground up object oriented, peer-to-peer, and for security.

Tecomp: A compiler for Eiffel (compliant with ECMA-367, ISO/IEC 25436). Tecomp is a command line compiler. It is committed to implement standard Eiffel. Tecomp works on Unix and Windows systems. The tecomp project is no longer under active development. Successor project: http://albatross-lang.sourceforge.net

Spanish translation and Eiffel adaption of the Open Book "How To Think Like a Computer Scientist", by Allen Downey. More information is in http://www.ibiblio.org/obp/thinkCS/

Free implementation of ELKS library

A calculator for programmers that does conversions between decimal, hex, octal, time, etc.

System for analysis of financial markets using technical analysis. Includes facilities for stock charting and futures charting, as well as automated generation of trading signals based on user-selected criteria. Operates on both daily and intraday data.

Stores and retrieves files in an encrypted archive. Also manages files stored on CDs and DVDs. Other functions are incomplete. PLEASE NOTE: you need to download both an Objectify release and a Public Objects release.

Referendum is a community-creation web toolkit focused around issues and resolution through voting. A web aplication used for understanding and empowering on-line communities through the democratic process, based on a completely open source foundation

The canvas widget is a EiffelVision2 widget that supports zooming, panning, and animation of the displayed graphical objects.

The Eiffel Windowing System is a small Eiffel library providing an SDL-based windowing system (and possibly other frontends in the future).

EWG (Eiffel Wrapper Generator) is a tool that generates Eiffel wrapper classes for C libraries. It can be used to create libraries that bridge the gap between Eiffel and C. It aims to work for arbitrary ANSI C and with all common Eiffel compilers.

EiffelRSS is an Eiffel library to parse and write RSS. The goal is to provide the Eiffel development community with an easy to use API for RSS. It also contains a simple RSS newsfeed reader written with EiffelVision.

Generic Game Framework in eiFFel (G2F3) aims to simplify the development of two player zero sum strategy games by separating game specific code from reusable generic code. So far, abstract board games are best supported.

The elj project aims to provide Eiffel software and libraries for the wider software development community.

Multi-functional batch sequence aligner incorporating Needleman-Wunsch, Smith-Waterman and Oommen-Kashyap algorithms along with compound alignment of secondary sequences.

A clone of the well-known Bust-A-Move game, completely written in Eiffel.

This project provides access to the collective works of the Colorado Eiffel Users Group (CEUG). It is intended that this site help promote and further the Eiffel language through a variety of portable Open Source initiatives.

These are simple command line audio tools to examine, change the gain, and convert wave and raw audio files.

CompuCell3D is a software framework for multimodel simulations of biocomplexity problems. It has been developed as an ongoing project for the Interdisciplinary Center for the Study of Biocomplexity at the university of Notre Dame.

**** THIS LIBRARY WAS MOVED INTO Boost **** New location: https://github.com/boostorg/contract C++ Contract Programming (a.k.a. Design by Contract or DbC). All Eiffel features supported: subcontracting, postcondition old and result values, optional contract compilation, customizable action on assertion failure, block invariants, loop variants, etc. Plus virtual specifiers, concept checking, named parameters.
