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.

Simple and effective frameworks in Eiffel : persistence, user interaction, report generation, communication. Add an abstraction layer on top of existing Open Source libraries (eiffel or other languages). Help developers focus on application requirement,

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

Various command line utilities to process files, one to replace strings in files, dump a file in hexadecimal little endian order, convert line feeds, 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.

A version of the SmallEiffel compiler (smalleiffel.loria.fr) with extra features, such as multiple threads, mysql database library, curses library, BeOS API library and built in option for boehm garbage collector.

Vtgrep stands for Visual Tree Grep and is a GUI to tgrep. It allows the user to build graphical representations of tree structures and then translates them into the tgrep syntax. provides search functionality, as well as search and result logging.

E.N.M.L. means Environmental Noise Model Language. The target of the project is the definition of a XML specification model mainly devoted to electronic acoustic data exchange. ENML aims to format ANY kind of noise measurement.

This project provides a multi-OS (Win32, Linux, QNX, etc) TCP/IP API layer for Eiffel. SmallEiffel and ISE Eiffel are currently supported. Others have not been tested as far as I know.

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.

eInteractive is a library written in Eiffel of software components that address the specific needs of interactive applications.

The Eiffel Zone is a resource center for multimedia, 2D and 3D graphics programming in Eiffel. This open source project covers DirectX Programming in Eiffel as well as the new EiffelFURY graphics and multimedia library.

ePalm aims to be a general-purpose library for allowing the SmallEiffel eiffel compiler to generate m68k-compatible code, and a series of classes which wrap the palm API such that an Eiffel developer can write a PalmOS application entirely in Eiffel.

The purpose of this project is to create an Open Source portable GUI library for Eiffel. It started as the "translation" of the excellent GUI library named FOX from C++ to Eiffel, but I hope it'll become independent soon.

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.

Multimedia Library for Eiffel

Secom is an object-oriented library of portable, reusable components for communicating over serial devices. With secom you can develop an application that will compile and execute on Posix and Windows, with little to no changes to the source code.

SEIF is a tool to process, compile and run PHP like scripts. In fact the SEIF scripts look like PHP scripts and should have at least the same power, but they use an Eiffel syntax. The goal of SEIF is not to create a new langage, but to make it possible

Extended BON is a superset of BON, a clear and concise graphical and textual specification language for software systems. This tool suite consists of a scanner, parser, documentation generator, and design model checker for Extended BON.

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 purpose of the UniLoop project is to create universal loop construction which will be effective and handy. Modify SmartEiffel(smarteiffel.loria.fr) to introduce this new loop construction.

ePolyglot is a set of libraries, classes, and tools which enable Eiffel to interoperate with Python and, to an extent, Haskell. Features for using Python objects from Eiffel, Eiffel objects from Python, and Haskell functions from Eiffel are included.

eXML is a XML Parser Framework for Eiffel. It features a native Eiffel parser and expat (using a C-bridge). Please note that we are using the mailing list at http://www.egroups.com/group/exml (and not the one on SF)
