Here is yet another statistical proof of Ada's success as a mainstream
programming language: the thread "Ada vs Eiffel - Ada programmer
approach" had 12 different contributors here on comp.lang.ada whereas
the symmetric thread on comp.lang.eiffel had just one (the OP) and not
a single response. Therefore, there are 12 times more Ada programmers
as Eiffel programmers.

I agree with the conclusion, but not with the way you came to it. (:-))

Yes it looks plausible that Ada is more popular than Eiffel, but measuring
it by number of responses is barely representative.

Like Dimitry, I'm not sure such a conclusion can comes from such a
fact. But it is sure by the way that Ada is more widely used than
Eiffel. Ada is more impressive than Eiffel. May be somebody (I did it)
come first to Eiffel and then after goes to Ada, after they understand
that Eiffel cannot fulfill requirements of real world.

What is sure, is that Ada user like the spirit of Eiffel, and Bertrand
Meyer, the author of Eiffel, was largely inspired from Ada.

There is a kind of friendship between Ada and Eiffel.

I'll leave you to work out the common enemy! :-)

But he hates Ada for some reasons I have never understood... I talk to
him (back in 1990 or 1991) one time the reaction was so bad...

Except from the Eiffel inventor, sad but true!

Are you talking about Bertrand Meyer ?


What do you mean ?

How could he be inspired from a language he hated ?

Yes.

Not sure he has said that Eiffel was inspired from Ada, maybe on the
early days... IIRC, in his book Object-Oriented Software Construction
there is very few (if any) references to Ada.

Hi,

In the second edition of this book, there are around 75 references to
Ada in the index.
And there is also a 20 pages chapter called "O-O programming and Ada".

By the way, in one of these pages, Oberon (which I completely forgot)
was also mentioned !

In the edition I'm looking at (1988), Chapter 18 is called "Object-
Oriented programming and Ada". That's a whole chapter that discusses
this language (more than is done for any other individual language; C+
+ just gets a one-page subsection). Plus, looking just at the index,
there appear to be 13 references to Ada outside of this chapter. The
beginning of Chapter 3.5 says, "Modular languages such as Modula-2 and
Ada offer a first step towards more appropriate solutions." (But I
guess that's not the same thing as saying he was "inspired" by it.)
Also, the Wikipedia entry for Eiffel lists Ada (along with Simula and
Z) as an influence---as a sidebar, with no attribution, so I don't
know how accurate that is.

A Google search didn't turn up much. It appears that Meyer has some
criticisms of Ada, but I couldn't find anything that would indicate
that he hates it. His Eiffel site has an article about the Ariane 5
crash, but he said there that the language couldn't really be blamed
because the problem could have been caught using Ada's exception
mechanism (even though I gather he doesn't like this mechanism) if the
programmers had used it properly.

Ok, so I've misremembered this part or I'm confused about which book it
was! Sorry about that.
