SmartEiffel is the GNU Eiffel Compiler. It is intended to be a complete, though small and very fast, Eiffel compiler. The current distribution includes an Eiffel to C compiler, documentation tools, a pretty printer, and various other tools including an Eiffel debugger. It also includes a large library of classes distributed under the terms of the MIT/X Consortium License. Eiffel is an advanced object-oriented programming language that emphasizes the design and construction of high-quality and reusable software.
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.
Amber for Parrot is an object-oriented scripting language for the Parrot virtual machine. It combines the traditional advantages of scripting languages with support for software correctness and large-scale software engineering. Amber for Parrot has syntax and semantics somewhere between those of Eiffel and Ruby.
