For many reasons I have to run old scripts made for perl4 under perl5,
and it's returning me tons of errors (else than \ before @). If anyone
has a fast solution or could tell me the differences between perl4 and
5, that'd of a great help to me.

This is a good solution except that there are other things in the file and

Thats right - you are, or at least if you arent you are asking in the
wrong place.
Please check out the module CGI.pm which is standard with all recent
versions of Perl - the documentation for that module has a section on
using a file upload field.

Of course this has all been discussed before on the appropriate group,
and it won't work. Did you want to raise some question about the

Obviuosly, this may fail if 2 different users, with same %ENV

I'm not sure exactly what you're trying to do here but ...
(My hubmlest appologies to everyone in c.l.p.m as I'm about to go a bit
off topic.)
If you're using client side Javascript you cannot start up a process on
the server unless you fire off a a url request, so if you have to have a
pre written javascript routine dynamically fill a variable from a perl
cgi then you could do the following.
Have your javascript app in a frame which occupys 100% of the screen,
with your perl cgi output in a hidden frame. Have the perl cgi write a
simple HTML file containing a form (for no other reason than because
it's really easy to get the value from a form field). Reference your
form field from the javascript.
This would work but I'm not sure if this exactly what you're after,
could you give a bit more detail.
I'm lacking inspiration today so forgive me if this isn't what you
wanted.

Message-Id: <37BD4FF3.E3EBB373@home.com>
Hello again Masters..
I found some info from a post by "Bart" to be an excellent
exmaple
of how I can use the S/R function to tweak text layout. But
I still have
a problem.. lend me thy wisdom..
To grab a substring of just alphanumeric items which are 80
characters or longer
and NO whitespace, I can find that with $text =~
m%(\w{80,})%;
But how do I pick out a substring of mixed character types
(letter, number and
symbol but not whitespace) that are >=80 characters long?
The encompassing text string is of variable length.
The placement of the troublesome periods, slashes and such
are variable.
EG: The substring could be
AB34567890AB34567890//34567890..34567890$$34567890AB34567890AB34567890AB34567890
and be burried within a paragraph of normal english words.

I think he wants a visual pointy-clicky Rapid Application Development
thing that spits out Perl at the back. Or some wizards or something.
After all, he compared it to FrontPage, where he doesn't have to write
any HTML tags but just "designs" a page.
Maybe he wants Visual Basic, or possibly a Perl consultant.

Subject: merging complex hashes?
Message-Id: <37BD44F2.B858D7B8@pc-plus.de>
Hi,
I have the sick desire to merge two complex hashes - more to the point,
I have
objects which contain objects which contain...., and when changes are
made, I
want to add those changes to the existing objects, without killing the
other
information.
ie:
$persobj = $newobj; # no good, data in $persobj gets deleted
%$persobj = ( %$persobj, %$newobj ); # better, but only merges the keys
of the
# top level hash.
I've written a routine to do a deep-merge, but it has problems, and I
was
wondering if anyone has already written a module to do this?
Many thanks in advance,

Subject: new to perl and a bit stupid
Message-Id: <7pjgph$km2$1@nnrp1.deja.com>
this is probably a very dumb question, but I've never used perl before
and I'm trying to write a script in it.........
I'm trying to extract some data from a file which is split up into
several sections, I'm only interested in data contained in one
particular section which has the form:-
SECTION HEADER
lots of text lines
that i want to do
something with
^$ (blank line marking end of section)
If I was writing this in awk I'd start at pattern /SECTION HEADER/ and
use the 'getline' function in a loop to get all the text lines until I
hit a blankline. Alas sob, sob there's no getline in perl so I'm stuck.
I've done a2p and this gives me a subroutine for getline (which
incidentally when I put it into my script doesn't work) but I'm not sure
that this is the best way to do it, I have an inkling that maybe I
should be putting the text lines of this section into an array and then
reading each $line of the array? but I haven't got a clue how to
construct it.
I'd greatly appreciate any help, and if somebody could spoon feed me the
code that would be even better.
Many thanks

The concept that an object is nothing more than a hash which knows
about itself is indeed very nice, and flexible, but I also have
problems with it. (although I must admit, I'm no OO guru)
For example, if you want to provide information about which attributes
an object may have, this is often done with a template hash in the
class, but derived classes can't use this template hash (although I
found several ways of passing information back and forth, they all had
their problems) - this is only partly because the class variables
aren't inherited - they really need to be 'merged' somehow (IMHO).
Another problem that I have is that methods defined in a base class
can't access the class variables of the class in which they are
called. Again I had trouble with this when checking for attribute
validity - the get and set methods could only access the attribute
template for the base clasee. (I know you can have an {'attributes'}
key in the object itself - but this causes problems when you have
persistent objects - the database get's filled with 'useless data')
Anyway - if you've got Sriram Srinivasan's "Advanced Perl Programming"
book, on page 135-137 he gives his 2c on the topic of inheritance.
Essentially he suggests that you think about 'interface
inheritance' instead of 'attribute inheritance'. I've now tried it,
and I must say I find it a better approach for perl programs - whether
it applies to OO in general I dare not speculate.
In essence, I reduced my classes to a minimum, and now have a lot of
'containers' which know about the interfaces of the objects they
contain. In my view not perfect, but quite OK.
Hope this helps,
Steve

Except the stash. Indeed, "Daughter::" is a key in the stash
%Grandmother::Mother:: . Why? Dunno. It seems silly, and inefficient to
me, that Perl has to traverse the tree main:: -> Grandmother:: ->
Daughter:: to find the variable $foo in
$Grandmother::Mother::Daughter::foo.

try Vim 5.4 from http://www.vim.org - it has binaries for Win9x and UNIX,

Choose Vim, Emacs, Ultraedit or whatever but don't use notepad for Perl :-)

Yes. Go to the links list at
<http://www.perl.com/reference/query.cgi?section=editors>; in particular
the link to "Perl for Win32 Editors".
One that is (still) missing from that list is the GWD text editor,
downloadable from <www.gwdsoft.com>. Not free, but not expensive either,
it has a (crude) syntax highlighter for Perl, and if you install Perl as
a "tool", you can launch the script from within Perl, and capture the
output into a window. Nice.

I want to learn more about the upcoming 5.6 perl threads model.
I have built a large, production-quality system on the current model (I
know, that's not recommended, but I had my reasons) and what to
understand what's coming so I can plan for it (and comment on it).
I have seen Sarathy's realaudio comment (but not heard it--firewalls
stop realaudio).
Thanks for any pointers you can provide.

Subject: Perl without C compiler.
Message-Id: <37BD4D4D.5B71612@midwal.ca>
Dear Experts!
I have to move my programs and perl scripts from a development machine
to a production one. By convention we have no C compiler at our
production environment. Both computers are Sun UNIX boxes.
1) Is it possible to install perl without C compiler (just copy a file
structure from one computer to another)?
2) Theoretically, I can install C for a short time at production
computer, install perl and delete C. Will perl work after these actions?
In other words: "Does perl need C compiler?"
3) Is it possible to install new perl modules without C compiler?
4) Are there any other solutions for this job?
Regards,
Serguei.

Doran got my vote on this one too..
Chances are you might want to consider uninstalling Apache, PHP3, mysql,
Mod_perl and the like and reinstalling from the source code... it may take
time and grief but NOTHING compard to the grief of manuals and docs that
relate to links that Redhat in it's wisdom has ignored when putting togther
the RPM's.
The benefits are docs, etc.. that MAKE SENSE... and trouble shooting that
you can actually use...nothing beats that ever

This comes close:
$\ ="\n";
for ([1,2], [3,4], [5,6]) {
my($i,$j) = @$_;
print $i+$j;
}
although it's probably not the same. And then, there's this:
$\ ="\n";
my @ary = ((1,2), (3,4), (5,6)); # = (1 .. 6)
while (@ary) {
my($i,$j) = splice @ary, 0, 2;
print $i+$j;
}
I bet you want this effect, but without the need for the temporary
array.

Hmm that's a bit harsh. You'll have to go a long way to find (big) sites
designed specifically with lynx in mind. Perhaps that's why you
keep going to plain text archives (come back gopher, all is forgiven).
I like the cookbook snippets, the colour scheme & general design,
the discussion/articles (eg recent ones on prototypes).
A useful non-WWW addition would be a news server (news.perl.com?)
with many specific groups on DBI, CGI, XML, daemons, win32, etc.
Perhaps with a web interface to this as well.
And existing mailing lists (eg modperl) could be mirrored there.
For content, I *really* like http://tpi.perl.org/news.html

_What's_ a bit harsh? If you have a point in mind, then quote that
point. (Not the entire posting, frchrissake).
What the heck do you think you mean, "sites designed specifically with
lynx in mind". If a site is designed _for_ the WWW, then Lynx is not
excluded. While it's possible to apply a few simple tips that produce
better results for Lynx without doing any harm to anyone else, I don't
know of anyone (except perhaps where Lynx is the specific topic of
discussion) who designs _specifically_ for Lynx: that would be to
pervert the whole idea of the WWW.
> Perhaps that's why you

What the heck are you doing here if you have a religious objection to
plain text? Look, O Purveyor of worn out Straw Man Arguments, it isn't
about plain text, it's about proper techniques of graceful fallback on
the World Wide Web.

It wont, in fact cant possibly help: most of the garbage in this group
is the result of the clueless posting inappropriate things in the first
place - creating new groups will just create more targets for these
inappropriate posts. If people arent clueful enough now to post their,
say, CGI,HTML,Webserver questions to the correct group and not here I
cant possibly see how this can help.
These kind of suggestions come up every once in a while like some kind of
weird ritual and the conclusion is always the same - we dont need more
groups we need more clueful posters.

The technical term is that each item must be an "L-value": you must be
able to put it on the left side of an assignment, as in { $x = 3 }.
>Cool.
Indeed. Also try this variation:
@a = ('A'..'Z');
$x = 1; $y = 2;
foreach ($x, @a[5..8], $y) {
$_ = "Bonzo was here!";
}
print "\$x = $x\n";
print "\@a = @a\n";
print "\$y = $y\n";
Inside the loop, $_ serves as an "alias" for the original scalar, so you
end up modifying the originals.
