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.

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.

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).

Fine is a derivitive of the SmallEiffel compiler. However, in an effort to improve (?) upon the Eiffel language it has some additional and modified features. Every effort will be made to keep it upward compatible.

Multimedia Library for Eiffel

Basic-level XSLT 2.0 processor, written in Eiffel.

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.

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

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

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

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.

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.

Even in the simplified two dimensional HP-model (hydrophob/polar) the prediction of proteinfolding is NP complete. We implement a brute force algorithm with serial and parallel execution to solve short inputs of HP sequences (0-1 bitstrings). Selbst im vereinfachten zweidimensionalen HP-Modell (hydrophob/polar) ist die Proteinfaltung bereits NP-vollständig. Hier implementieren wir einen brute-force Algorithmus zur Lösung kurzer Eingabesequenzen (0-1-Bitstrings) für die Proteinfaltung.

Design Pattern Wizard GUI - Design and implementation of the wizard (GUI and “business model”) in Eiffel

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

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.

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.

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/

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.

This program is for a (chinese) restaurant to take orders for takeout or delivery. It keeps a database of customer information (for repeat customers). It prints 3 copies of the order (store, kitchen, customer) and tallies the orders each day.

Free implementation of ELKS library

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

Attempt of a portable cross-language object-oriented benchmark . So far supporting C++, Objective-C, and Java. Support for Smalltalk, CLOS, CSharp, and Eiffel is in development.

Queue is a 3D billiard game. It features a realistic physics engine and supports different billiard variants.

**** 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.
