Bye, bye?

Bye, bye?

[Wes Groleau]

Long, long, ago, I said that I would change careers
rather than do more than 10% C++.

I was a substitute teacher for two years, but the bills
caught up.  I'm still keeping my promise, though.
I do Visual Basic at work, and perl at home.  :-)

Actually, I kind of like both, but they're not Ada.
Someday I may get back to Ada at home.  But no amount
of wishing is going to make it happen at work.

(Consider this a troll and ignore it.  Just thinking out loud.)

Given all the free Ada tools out there, why not use it at home? I certainly 
have.

Dialup connection.  Upgrading the Mac developer tools to
prepare for installing GNAT will take approximately 26 hours.
We need to use our phone at least once per day.  I could buy
them on a CD, but that's $20.

But I'll do it someday.  I don't do enough home programming
to make it really urgent.

Wes,

well if you update to 10.4 then the dev tools are on the cd.

As the earlier version was when I got 10.3

Like I said, I'll get it someday.  Pay off a few bills
and then go broadband.  Or save up for the $20 CD.

Not like I have any time to use it....

Pray tell, what is it that you do in perl at home?

Very little.  But much of what I do depends on hashes
(associative arrays), which are built-in to perl.
Plus I attach the hash to a DBM file.

To do that in Ada, I'd have to not only upgrade Xcode
(not an option right now) and install Ada (easy, but
requires Xcode), but I'd also have to find or build
a hash package (not hard) and/or a DBM binding (a little
harder).

The right tool for the right job.  Ada _usually_ is,
but not always.

When all you have is a perl, everything looks like a string.

Also, I'm working in UTF-8, which perl handles
as easily as ASCII.

Associative arrays will be included in the next version of Ada, as part
of the standard container library:

ada.containers.hashed_maps
ada.containers.indefinite_hashed_maps

There will also be an ordered version (which does the same thing as the
hashed version, but with a different time complexity; it's also a bit
simpler to instantiate):

ada.containers.ordered_maps
ada.containers.indefinite_ordered_maps

There are also hashed and ordered sets (for use when you don't need a
separate key and element).

You can get a reference implementation in the ai302 subdirectory at the
charles.tigris.org website.

Look for the files named a-c*.ad[sb] .

If you like perl, how can you possibly object to C++?

I didn't say I _like_ perl, I said it's not bad.

To tell the truth, the reasons for my objection to C++
(some of them) might apply to perl, too.  But I never
made the pronouncement about perl that I made about C++.
:-)

Actually, perl does have some safety features that C++
had to forego due to the baggage it inherited from C.

Sometimes, reading a perl book, I am surprised that it's
able to do something Ada-like (though not as pretty to
Ada-accustomed eyes).

Other times, I am amazed at how many versions of perl
have stubbornly refused to incorporate anything resembling
a case (switch) statement.  Though rumors are they're
giving in to that in version 6.

I remember hearing a rumour that Larry Wall seriously considered writing Perl 6
in Ada.  One of his quotes on the language:

    I remember being impressed with Ada because you could write an infinite
    loop without a faked up condition. The idea being that in Ada the typical
    infinite loop would normally be terminated by detonation.

Maybe he found out how to do it in C/C++:

for (;;)
  {
  }

  They aren't the same.  Within the C language, that program's single
task would indeed only be terminated by detonation.  But an Ada program
could well have other tasks doing useful things at the same time as
the one task was in an infinite loop.

Well, I had the three ... missing indication that indeed something usefull
is happening inside the inifintive loop. Apart from that - you are right.

But it is a nice examample for readability:

loop
   ...
end loop;

vs.

for (;;)
  {
  ...
  }

C/C++ 10 characters of with 6 special characters - Ada 12 characters of with
only 1 special character. And the (;;) beeing specialy obscure.
