Freeware Descriptions:
EiffelStudio is a full-featured IDE for the Eiffel programming language.
Here is complete features (taken from authors site):
- Complete compiler for the Eiffel programming language, with both high compile-time speed and high-performance executables
- Support for Windows, MacOS X, Linux, *BSD, Solaris and other operating systems
- Smart code editor
- Sophisticated multi-view browsing and viewing facilities
- Interactive debugger
- Graphical modelling tool for UML and BON with full roundtrip
- Refactoring support
- GUI development tool and fully portable GUI library
The Eiffel compiler creates C code that is then handed to a standard C compiler. As a result, Eiffel programs have a run-time performance comparable to those directly written in C or C++. At the same time, Eiffel is an object-oriented and strongly typed language. EiffelStudio uses a highly efficient compacting garbage collector to free the developer from the burden of memory management.
What’s New in version 6.4.77440:
- Taken into account attachment status of formal generic constraints when checking conformance and detecting VUTA errors when target type is a formal generic (this is a new ECMA feature).
- Fixed up precedence of the new `attached’ operator as previous version could cause some spurious syntax errors.
- Speed up C compilation of E1 directory under Windows using VS 2005 on 64-bit.
- Improved speed of errors and warnings when the number reaches more than a thousands errors.
- Fixed full class checking of inherited binary expression. Enabled proper evaluation in the debugger of equality expression a ~ b.
- Fixed memory corruption that could occur while accessing elements above the 4GB limits for arrays larger than 4GB in size.
