Within a perl CGI.pm script I've generated a perl hash. How can I get
the contents of that hash into a two dimensional javascript array so I
can validate against it?
TIA

Umm, I must be missing something here. Won't it be a *lot*
easier to validate 'against' the hash in Perl, using the functions
Perl has for working with hashes? This doesn't look to me
like a good application for JavaScript. Look up these Perl
functions and see if they'll cover what you need:
delete()
each()
exists()
keys()
values()

Yes, it would be a snap in Perl but I want to do the validations before the
form is submitted.
The user is editting a list of employee numbers and the javascript function
would lookup and return job titles on the fly.
I can do this easily after the form is submitted but I thought it would be
slicker to do it interactively.
That said, can it be done?

If I understand what you are asking, then I think the answer is
no. If you write a JavaScript script which can do the validations
on the fly before the form is submitted, then it needs to do all
the validation before the Perl program *sees* the submission.
If you send the pieces to JavaScript via your Perl program,
then it goes through the Perl program first on its way, and the
validation could be done easier in Perl.
So either I'm missing something you're doing in your CGI script
which you haven't shown us, or else you may want to consider
asking in a group like comp.infosystems.www.authoring.cgi .
Or getting a smarter responder. :-)
HTH,
David

Hello, World!
Has anyone tried compiling Perl with Borland C++ Builder 4 on a
Win98 box?
How about embedding Perl in a Builder application, or vice-versa?
If it hasn't been done yet, I would be very willing to help with
the effort. Is there someone knowledgeable who would be willing to
lead?

I think the significant debate is specifically about whether XSL should be
used for formatting. I trust that the transformation part of XSL is not
considered to be "useless". :-)
In any case, if one is really seriously doing XML it's necessary to
recognize that there are more tools available on Java than there are in
Perl. Use Perl when you can, but use Java when you must. An XSL problem,
in particular, pretty much requires you to use Java at the present.
There are some really handy lists of XML tools by standard. Go to the
SGML/XML page on http://www.oasis-open.org/

Folks,
Is there a way to make perl-debugger read the debugger commands from a
file? Also is there a way to set initial break-points using the
~/.perldb file?
Even the aliases I create in the ~/.perldb file are NOT working. The
alias
$DB::alias{pc} = 'print "alias for pc\n";';
defined in ~/.perldb works; but the alias
$DB::alias{pas} = c_debug::c_print_assoc;
does NOT. Any idea why the above alias does NOT work?
Thanks for your help.

Subject: Perl Everywhere : That's what I want
Message-Id: <7lhnb3$3q6$1@nnrp1.deja.com>
hi,
i love perl and programming with it. it's a great language for quick
prototyping and now with lots of modules is great for writing big apps
as well. I'd like to see more apps written in Perl - I'd like to see
Perl everywhere.
However, the things commonly stated as Perl's shortcomings are that :
1) It's horrible to maintain Perl code
2) It's not quick
3) It's only good for CGI and short&dirty scripts.
Also, we know that Perl was a platform-independent language much before
Java. We know that Java is S-L-O-W. We know that Java & Perl are both
compiled-interpreted. We know that Perl is FUN.
So, why don't we have Perl Everywhere ?? Also, what should be done for
us to see Perl as a more dominant force in the Land of Programming
Languages ??
What changes does the language require & is it moving to those changes
??
I'd like you all to put you collective thoughts in coming up with
suggestions to see Perl Everywhere

While all is relative, that's pretty easily argued against.

However, the Perl community does not spend millions of $$$ on
PR to spout off about the wonders of its language, as some do.
Hence:
> However, the things commonly stated as Perl's shortcomings are that :
Note that there is a huge difference between what is 'commonly
stated' and what is true. Example case: Is Paul dead?
> 1) It's horrible to maintain Perl code
It's horrible to maintain ghastly Perl code. Just as it's
horrible to maintain ghastly C code, and C++ code, and...
It's the programmer, not the language. Take a look inside
the Perl modules, and you'll see that Perl can be beautiful.
> 2) It's not quick
Au contraire. Try reading Kernighan and Pike. What was faster
than Perl in their test case? C, by a factor of 3 - 5 times.
That was it. Perl came out faster than C++ some of the time.
Perl was light-years ahead of Java.
People who say this usually have a single test case for their
'proof', at least in my experience. But running Perl for CGI
without using mod_perl or fast_cgi or PerlEx is just cheating.
It's not at all the way you would do it in the real world,
which is what really matters.
> 3) It's only good for CGI and short&dirty scripts.
True, if all you do is CGI and short&dirty scripts. False
otherwise. Actually, there is nothing I do in my job which
is not suitable for Perl.. well, except for getting the
coffee. The Fetch::Drink module still needs a lot of work.

I suggest that you start a massive, multi-million dollar,
international ad campaign showing a Perl camel kicking the
tar out of a tiger, a rhino, a sea lion, and a couple slender
lorises.
Maybe a mastodon and a lion and a jersey cow too.
And get James Earl Jones to do the voiceovers. That should

Subject: Perl Exensions without XS
Message-Id: <7lin58$f6p$1@nnrp1.deja.com>
For a while I've been thinking about writing a Perl extension, but have
come a cropper with the XS stuff, to me it all seems very opaque. I've
written extensions to Python before, and was looking to get into
extension for perl in much the same way... anyway I finally sat down and
figured it out.. So I thought I'd post my little test program in case
anybody else was having the same idea...

BEGIN { $| = 1; print "1..9\n"; }
END {print "not ok 1\n" unless $loaded;}
use Test;
$loaded = 1;
print "ok 1\n";
######################### End of black magic.
# Insert your test code below (better if it prints "ok 13"

Depends on what you mean by "long term". Someone coming out of
college/university has at least about a 40-year career ahead of him/her.
In this field, who can predict what's going to happen even ten years from
now? Ten years ago, how many people had heard of Perl? How many people
had heard of the WWW? How many people were programming in C++? Etc.
The only things that will remain constant are fundamental algorithmic and
problem-solving skills, and the ability and willingness to learn new
technologies.

I totally agree - it is a matter of adaptability - I have been programming
for the best part of twenty years now and I would say that the stuff I am
working with now is not going to be what I am going to be working with in
twenty years time. Learning to learn is possibly the most important thing.
That said I would not recommend anyone to learn PHP as a career move as
I wouldnt recommend anyone to learn Javascript - they are special rather
than general purpose languages.

No, but PHP just might stand for "PHP H'aint Perl".

The standard formats can be found under the listing for sprintf().

Thanks for correcting me. I wasn't sufficiently familiar with the HTML

Subject: Pls hlp with regex
Message-Id: <7lihge$cmg$1@nnrp1.deja.com>
I'm looking for a regex that replaces all occurrences of anything like
<a href=javascript:OpenPlayer('nfl','4290') >
by "xxx".
I.e. I want to replace all hyperlinks that contain the
string "javascript".
My solution:
s/a[^>].*?href.*?javascript.*?>/xxx/gims
does not work. It kicks in with the first <a href...> tag it finds,
even though if that does not contain the string "javascript".
Thank you for your help.

Why do you need the href in the regex? There's no other place for
'javascript' to show up in an a tag... As long as you specify the space
after the a you are only affecting a tags...

That will convert:
<p>a sentence about hrefs and javascript</p>
into:
<p>xxx
Uh oh...
: >does not work. It kicks in with the first <a href...> tag it finds,
: >even though if that does not contain the string "javascript".
: s/<a .*?javascript.*?>/xxx/gis;
: Why do you need the href in the regex?
That will convert:
<a name="about_javascript">
into:
xxx
Uh oh...

: 'javascript' to show up in an a tag...
Says you.

Using regular expressions to parse HTML is futile. They do not
have the expressive power required for that job.
HTML::Parser can do it though...

I rechecked this:
I got this error message for example when trying to execute a file with the
right execute permission in the correct cgi-bin directory when this file is for
example a html page.
So can it be that this system you are trying to get this script running does
not know how to execute it?
Either at the beginning of your script this line is missing: #!/usr/bin/perl -w
or something with your perl interpreter is just not right.
Anyway the problem is definitly, that your script is not executed but
interpreted in a way by your webserver.
Hope this helps.

No. Your script probably runs. Otherwise, you'd get an "internal server
error". But I bet it doesn't print a "Content-type: text/html\n\n" line
at the very start.
