SmartEiffel 1.0 Released
·
· Score: 5, Informative
The ELJ project - http://elj.sourceforge.net/ has been successful in providing much needed multiplatform libraries to SmallEiffel/SmartEiffel developers.
There are even libraries for Regular Expressions and for those who like the perl way of doing things - see Perlish.
The 0.5 release announcement in comp.os.linux.announce gives more details. The ELJ project is undertaking the necessary work to move from SmallEiffel to SmartEiffel.
There are many other open source Eiffel projects:
GOBO - lex, yacc, xml, data structures, date/time libraries and
eposix which aims to provide a a 100% complete Eiffel binding to Standard C and POSIX.
Eiffel has come a long way over the years. Misconceptions still abound. You can now develop multiplatform applications using open source Eiffel tools and libraries. There are small hurdles to jump as there are with anything. Give it a try and become involved if there is something about Eiffel which you find appealing.
Given that the source isn't included, I can't help but wonder at what the code looks like
Just go up a level and you will find plenty of C++ and Eiffel code, along with Victor's notes including `Project Plan Summary', `Time Recording Log' `Defect Recording Log' for both C++/Eiffel versions. The previous link was just an Appendix.
given statements like In fact, Eiffel (by its use of copy-by-reference instead of by-value) could realize big wins over C++ , which shows an apparent unfamiliarity with C++ reference parameters, which can make huge differences in execution time with strings.
Victor has a strong background in C/C++ and has even developed game software that has brought in a little cash and the thrill of seeing my game on the "cheapware" racks at the local software store.
Eiffel is not for everyone, most can't even (and don't want to) read the Pascal/Ada syntax. The language landscape is incredibly competitive and it is just interesting to note that Eiffel has moved along with the rest. As I said in another post, SmallEiffel has added a new dimension to the Eiffel world. For most this doesn't matter, but at least we should know it exists.
There are a fair amount of blatent errors on that page in regards to C++. For example, "super()" is a java construct, not a C++ one.
If you can send me the list, I would appreciate it. I have had a few other contact me over the last couple of months and will do an update shortly (hopefully with your corrections).

The wxEiffel GUI library provides a comprehensive interface to the wxWindows GUI. Database interfaces to Firebird, sqlite, berkeley db, mysql, postgres.

Maybe your views are based on outdated information? For a more recent view see:
BTW, Ian's C++?? Critique is now a completely updated/rewritten book titled: Objects Unencapsulated: Eiffel, Java and C++??
From the Eiffel/C++ perspective, the following articles are worth a look:
( the application of Design by Contract in many contexts is also available)
( The results for compile time, Executable size and Executable speed may surprise a few!! SmallEiffel - The GNU Eiffel compiler - really adds a new dimension to the Eiffel World!! )
The Eiffel to C++ terminology mapping page is also worth a look.
