Awesome Eiffel

Below is a curated list of awesome Eiffel and Eiffel libraries, resources and tools.

About Eiffel

• Eiffel is an open source ISO/EMCA standard programming language.
• Eiffel is statically typed, class based and object-oriented.
• Eiffel is easy to learn with a simple clear syntax.
• Eiffel has an excellent open source IDE, compiler and debugger in EiffelStudio.
• Eiffel has a large range of libraries available including web, database and GUI libraries.
• The Eiffel compiler provides static protection against calls on null references.
• With Design by Contract tightly integrated into the Eiffel language, one can create better, safer software.
• Eiffel has a easy to use built-in concurrency model called SCOOP.
• Eiffel has automatic memory management with garbage collection.
• Eiffel allows simple multiple inheritance.
• Eiffel exposes lambda calculus as Agents, or objects that wrap computations and closures.
