Uh, doesn't query-replace-regexp do exactly that? The syntax of the regexp
may be slightly different, but I think the capability is there.

Sure it doesn't work as well as it used to,

Jamie, you gotta learn to recognize sarcasm when you see some. Unless I'm

No, he's just being sarcastic.

Agreed, but still, having more powerful regexps in emacs won't be bad.
Of course, embedding perl in emacs for only that reason is ridiculous.

What's wrong with perl? To me perl is the triumph of utalitarianism.

Well; I can't imagine any other language that would allow me to
to do Newsgroup server scan and looking for specific articles by
just few lines of Perl5 OO code. Hey; i can even do batch Http
search on selected URL pointers with handfull of code.

It's simply amazingly powerfull compared to any other language.
And if you comment your code well, it's not that hard to understand
at all.

Cheers!

=o= I would say Bourne shell and Lisp, except not really Lisp,
more like awk, and not in a "worst aspects" way, either.

=o= It corrects my one and only complaint about Emacs Lisp, in
that it uses egrep-style regexps instead of grep-style regexps
(hence, no "backslash-itis").

=o= GUILE would win me back over by doing the same.

The two points are valid, and I doubt that anyone in the so-called "higher
ranks" of Perl would try to put these ideas forward. A current interview with
Larry Wall (the creator of Perl) in SunWorld OnLine shows that certainly
doesn't buy into the one-universal-tool theory. But on what grounds do you
label Perl "braindead"? I speak from the standpoint of managing the development
of a product that includes over 50,000 lines of Perl code, a system that has
to run identically and cleanly on more than 5 different architectures, a
requirement that Perl meets very smoothly. I have many tools in my box, Perl is
just one, and for the things it is suited to, it is the best tool. XEmacs is
another, as are Lisp in general, C, various symbolic debuggers, etc.

Jamie> Some people, when confronted with a problem, think "I know,
Jamie> I'll use regular expressions." Now they have two problems.

The first of which is assuming that one solution fits universally to the whole
set of problems, yes. My guess is, the second problem is an irrational
resistance to new tools and techniques to solve problems.

Check out Python. It can do all this and more. It might be
minimally more verbose than equivalent Perl, but then you might also
have a hope of reading your own code a month later.

The Pattern Extraction and Reporting Language making extensive use

Perl might be an abomination, but at least it's free.

Sounds like a certain GUI application that pretends to be a web browser cum
mail user agent cum newsreader, that spends most of its time making 49 Meg
core dumps on my HP workstation. But then, I'm not running a Micro$oft box,
so I'm not a real concern.

Well, I was going to keep this "debate" fairly civil, but if you wish to
resort to sniping, I'd say working for Netscape and criticising other software
as "brain-dead" must really define "living in a glass house".

Jamie> If Perl gets you through the day, great; more power to you.

Compared to what? C? Is that what you rocket scientists are using to code
Netscape? I have a (supposedly) stable release version of NS 3.01, as my
company has a corporate-wide license agreement with NC. This "stable" released
product last week dumped a core nearly 50 Meg in size. What was it doing at
the time? Sitting on my internal (intranet) webserver's home page, a page with
no cutesy animated gifs or such, and Netscape was iconified. *YOU* may wish
to label Perl as braindead, but it is a considerably more stable piece of
software than anything I've seen come out of your company's domain.

You still don't explain why Perl is *wrong*. What is *wrong* about it. You
don't like the syntax? None of C, C++, Java or even Lisp are any more
naturally readable to a person new to the language.

Well, that's nice if it would make you happy, but what if there are people
and companies out here for which a CLOS/Lisp Machine environment is not the
best approach to the problems at hand to be solved? Or do you think that if
CLOS is your hammer, all the world's problems *really are* just nails?

Yes, the regex engine is one of the strongest features. I'd much rather do any
form of data processing in Perl than Lisp. Maybe programmers with less
experience take simplistic approaches; that doesn't make a language itself
bad. If so, I'd love to see what havoc a novice Lisp programmer can wreak on
the repuatation of Lisp itself.

I have no idea to what extent you have evaluated Perl, or to what other
languages and standards you are comparing it. I wouldn't dream of trying the
tasks I am responsible for in Lisp, and they would be very difficult in C
since one of the requirements is an ability to run on 5 or more different
architectures (none of which is a Lisp Machine). It's really kind of insulting
to listen to someone rave on about how flawed Perl is as a language and
development tool. I expect this sort of I-know-whats-best elitism from someone
like Richard Stallman, but I don't accept it from him, either.

Jamie> Maybe Java will save the day, once someone straps a Java
Jamie> front end onto the gcc back end.

Maybe no one language will ever save the day. Maybe we're doomed to have to
always choose from a variety of tools to select the one most suited to the job.

While we are at flaming netscape, I should tell about something much

Those kinds of unsolicited and unauthorized control messages get more

Any questions?! :-E
