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.
ePeriodique is a graphical application which displays the periodic table of the elements. It shows basic data for each element, pictures, Bohr models, and lattice structures. It tries to use the EFL way and provide two themes, one for the desktop (default) and one for small displays (small).
EWG (Eiffel Wrapper Generator) is a tool that generates Eiffel wrapper classes for C libraries. It can be used to create libraries that bridge the gap between Eiffel and C. It aims to work for arbitrary ANSI C and with all common Eiffel compilers. It is ideal for creating cross-platform, cross-Eiffel-compiler, and cross-C-compiler C library wrappers. It can handle pretty much all ANSI C, but understands Visual C and GCC extensions as well.
