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.

====Sather====
Eiffel was forked into another programming language called [[Sather]] fairly early on in its lifetime.
Eiffel was forked into another programming language called Sather fairly early on in its lifetime, the main complaints the original authors of Sather had with Eiffel was that it was not available in a free version and that its performance was slow. Sather is more strongly typed than Eiffel in the [[Modula-2|Wirthian]] sense and takes on some of the features of [[Oberon]], it was quite popular for a while but interest in the language waned after the popularisation of [[Java]] as with all other object oriented languages, but also Eiffel itself over time has gained some of the characteristics that the authors of Sather were aiming for. There were a few dialects of Sather available, the main two were '''Sather-K''' developed by the Institut für Programmstrukturen und Datenorganisation (IPD) at the University of Karlsruhe  and the original version developed at the International Computer Science Institute (ICSI) at the University of California, the Sather-K version got mothballed after the IPD turned its attention to Java and the ICSI version died a quiet death after being handed over to the [[Free Software Foundation]] (GNU) for further development.  


There was at one time a EMX Sather port available for OS/2 but it has been lost in time, you can actually compile and run the ICSI, Sather-K and GNU versions and run it on eComStation but since there are no OS/2 bindings available any more that is a bit pointless exercise. The main advantage Sather still has over Eiffel is that it is slightly simpler and thus easier to learn, but as Eiffel is very easy to learn as well the difference is not great.

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.
