Object oriented structured programming language in the Algol family, originally designed by Bertrand Meyer and partially inspired by Simula and Modula-2. Much like Smalltalk, Eiffel has also suffered in the last few years due to companies that built commercial tools for the language have turned their attention to Java. The language has a reputation as the language you turn to when other languages and tools have failed, particularly with large programming projects, although this has been downplayed a little as more tools for "programming in the large" appear for more mainstream languages. However the clean object-orientation features of Eiffel really have no like in other languages even with other O-O languages such as Smalltalk and Java, this means that creating code that is easy to re-factor or change outright makes it a really coherent tool for prototyping and for software that needs to be adjusted frequently such as market trading software.

Eiffel was forked into another programming language called Sather fairly early on in its lifetime.

Standards

  • Bertrand Meyer: Standard Eiffel (revision of preceding entry), ongoing, 1997-present.
  • NICE - The "Nonprofit International Consortium for Eiffel" organisation, did some of the work on standards prior to ECMA-367.
  • Standard ECMA-367 Eiffel: Analysis, Design and Programming Language - 2nd edition (June 2006) - The first international formal Eiffel standard, later adopted by ISO as ISO/IEC 25436:2006.
