The Eclipe Eiffel Development Tools (EDT) are a set of plugins which implement a full-fledged, highly integrated Eiffel development environment based on the Eclipse Platform. The EDT plugins contribute a number of facilities specific to Eiffel, such as an Eiffel builder, a Cluster Explorer, and Refactorings.
Origo is a software development and collaboration platform. It provides services that help develop software, such as source control management, issue tracking, wiki, release management, chat, blog, and forum. It uses an API to unify different tools and provides a common way to stay informed about changes in your projects. The API also allows you to integrate other tools into the plaform easily.
EiffelStudio is an IDE for the Eiffel language (ECMA-367, ISO/IEC 25436, and ACM Software System Award 2006). It includes: Eiffel compiler, Eiffel editor, Eiffel code browsing tool, Eiffel testing tool, graphical design tool, refactoring tool, debugger, profiler, and Eiffel analysis tools (Metrics, Dependencies, etc.). Eiffel generates C or CLI for .NET or Mono. Eiffel applies O-O principles and Design by Contract for high-quality software. Many Eiffel libraries are included: ADT, network, GUI, database, parsing (including an Eiffel parser), XML, Web, COM, and more.
G2F3 (Generic Game Framework in eiFFel) 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. This software is written using GNU SmartEiffel. The package comes with six example games.
Pylon is a compact foundation library for writing portable Eiffel software. It provides the classic data structures (lists, stacks, queue, sets and various tables) with associated access objects like iterators. Other useful clusters provided include: date and time, a simple portable serialisation facility, along with a few other utilities for number formatting and string parsing.
SNiFF+ for Eiffel is a 'fuzzy parser' which extends the SNiFF+ development environment for use with the object-oriented language Eiffel. You get syntax highlight in the editor, a class browser, cross reference browsing, and much more. It works independent of your Eiffel compiler and can even cope with source files with syntax errors.
EDA is an Eiffel implementation of the General Decimal Arithmetic Specification. It allows unlimited precision decimal arithmetic. By implementing the GDA Specification version 1.08, the library conforms to the requirements of the ANSI/IEEE standard 854-1987, while supporting integer and unrounded floating-point arithmetic as a subset. EDA is part of the SAFE project.
