Well, apart from the fact that that is _not_ how you actually access
Perl help on all (and an ever-increasing number) of workstations, sure -
that's not the problem.
(Mac users, for example, have had about 16 years to get used to the idea
of accessing help from the "Help" menu.)
But that's an issue for the individual platform porters to address, and
not the obstacle I was raving on about.

Hmmm, yes, well. Larry Rosler and I have addressed this in (multiple)
previous posts. In a word - inadequate.

And I reply (again) that it's the _lack_ of approachable documentation
(documentation that newbies can comprehend) that ships with the standard
distribution that's got my goat.

I am failing to see this point. I appologize if my thick headedness
comes into play, but I count myself among the newbies. I am a
programmer by hobby only. I am not an educated programmer (my degrees
are in political science and foreign policy) or a professional one.
I just _like_ Perl. I am that neophyte you speak of, and I have
found the majority of the documents to be _very_ approachable.
When I have had questions, I come to the newsgroups and ask them.
Hopefully, if I've worded my question well and provided examples
of my problem, I will get help and continue learning. While in
the process of learning Perl, I decided to learn C as well. I
find it to be much more daunting, simply because documentation
for C _is_ sparse. Most C programmers are educated and learn
the syntax from textbooks, I guess. But I digress. My point is
that millions of newbies are able to comprehend things far beyond
what you are willing to give them credit for. And while the
docs could be cleaned up and more tutorials added, I think the
existing base is wonderfull and very approachable.

You may keep complaining that there isn't any readable documentation
yet, but as long as you're sticking to a 2 year old distro... nothing
could ever be added.
But, 5.6 on Mac is in the works. Including the updated docs.

document.all - broke just about everything. There are _many_ others.
(In the analogy, map your understanding of "compiler/interpreter" to a
"web browser" and the "extensions" as the "document object model" -
it'll probably help.)
NN: document.layers.bob.<blah>
IE: document.all.bob.<blah>
Which means to do any dynamic HTML, you had to write JavaScript (or, as
Microsft calls it, JScript) to browser sniff and then fork execution
depending on the browser type... and version... and platform...
So we ended up with the nightmare of:
if (nn4up && win) {
...
} elsif (nn4up && mac) {
...
} elsif (nn3up && win) {
...
} elsif (nn3up && mac) {
...
} elsif (unix) {
...
}
else {
...
}
Which meant that web authors spent 70%+ of their time writing browser
checking code and coming up with multiple versions of their page to try
get a consistent behaviour across browsers (types, platforms, versions).
They waste their time doing this, instead of building _better_ websites.
Imagine the sheer lunacy of:
if (MS_perl) {
#!C:\system\framework\perl\
} else {
#!/usr/bin/perl
}
if (MS_perl) {
$doc = new Object(text,"Hello World!\n");
print $doc;
} else {
print "Hello World!\n";
}
The rot has already started, with Microsofts
infection^H^H^H^H^H^H^Hjection of capital into ActiveState.
For those that haven't been paying attention, didn't you know that
"ActivePerl, [is already] the most complete Perl package available!"?
On Windows, it also installs (by default): PerlScript and Perl of
ISAPI...
PerlScript is an ActiveX scripting engine that allows you to use Perl
with any ActiveX scripting host. At this time, ActiveX scripting hosts
include:
* Internet Information Server 3.0+
* Peer Web Services 3.0+
* Microsoft Internet Explorer 4.0+
* Windows Scripting Host
Goodbye security; sorry, doesn't run on Unix or MacOS.
Perl for ISAPI is a plug-in designed to run Perl scripts faster on ISAPI
compliant Web servers. Requires ActivePerl and an ISAPI compliant Web
server such as Microsoft Internet Information Server 3.0+.
Goodbye mod_perl; sorry, doesn't run on Unix or MacOS.
MARK MY WORDS - We will see an ever-increasing number of posts on
c.l.p.m along the lines of:
"My Perl script works perfectly when I test it on my machine at home,
but when I upload it to my internet service provider's web server it
breaks - what's wrong?"
A little probing later will discover that they are using features (only
available in ActivePerl) which go along the lines of:
$agent->processForm($myForm);
$agent->getEmail($myMail);
$agent->filterSPAM();
$agent->toastBread(3);
$agent->bakeCake('banana');
$agent->createWebsite('dom.com');
$agent->tieShoes($mySneakers);
print "Hello World!";
That will reinforce the impression that Active State's Perl is "the most
complete Perl" and that _other_ Perls are lacking. That the standard
distribution is lacking!
Microsoft are masterful at "embrace/extend/destroy" tactics, and they've
already lined up Perl as the next target. Unless something is done to
stop them, they _will_ prevail.
And NO amount of pontificating in the microcosm that is Unix will change
that. The war _MUST_ be fought on the Windows desktop.

Well, I think that your expectations about what the documentation should
be is what is causing you problems. The Perl documentation set is supposed
to tell us what Perl does, not how to program. To that end, it does
an admiral job.
A person completely devoid of any programming experience or expertise
is going to find *any* documentation or specifications daunting.

Then you shouldn't start with the docs, you should start with something
designed to help you learn to program. Now, I am on the side of the
fence that thinks Perl is an excellent language to start with, *primarily*
due to the wealth of documentation available.
Once a new programmer understands the things common to almost all
languages, the documentation becomes a great resource.

Every document I listed ships with the 5.6 distribution. I don't
know Macintosh, but if it doesn't ship with the complete doc set,
I'd say it's broken.

It's good to advocate. Advocation for clearer documentation is a good
thing, and you should continue to do so. In fact, I'm not in total
disagreement with you regarding the tools necessary to access the docs.
They could be better.

Nope, the value in _your_ variable $length is now 2.

clpm isn't exactly a love-in :)
And while I have great hopes for 'Visual Perl' and it's offspring, I would
doubt that they will reclaim ground in shops that have chosen other
technologies since changing a production site from the ground up is a big
job that VP may not be compelling enough to warrant. Time will tell.

No I'm not. But your @INC is funky. The installation procedure should
have added the "site" folder to @INC. It looks like it's missing on your
install, so it looks like part of the installation failed. I just wonder
if the fact that this is Win2k, has anything to do with that failure. If
anyone has experience with this, please share!
I'll have a copy of Win2k in a week or so, so I'll be able to test it

Assuming you mean pdflib by Thomas Merz (http://www.pdflib.com/), it
does come with bindings for Perl -- just not very good ones. Christian
Kirsch (the name similarity is purely coincidental) of the iX magazine
has made a rudimentary object-orientated wrapper for it, which is

don't know Christian's position on releasing and/or maintaining this

Anyone interested in this matter should probably contact Christian

Close, but you have the logic backwards. The OP wants to split on spaces,
not on words.

Of course the values of those are:
[0] "this
[1] is
[2] some
[3] text"
Are those quotes necessary?

You are looking to 'split' the string into its tokens.
@array = split (/ /, $text);
perldoc -f split

Don't do it this way. Check the perlop documentation under the
subheading "Quote and Quote-like Operators" and you will see that qw()
doesn't interpolate variables. So qw($variable) is interpreted as a
string literal, '$variable' and not as the variable holding the value
"this is some text"

I tried to install the module using PPM from Jenda's repository and it does
not seem to work. There is
something not working properly in the package. Is
there another location that I can get this package from.
I tried to copy the .gz file down and compile it myself,
but there is not Makefile.pl associated with it.
Any other ideas?

Hello James,
The MS operating systems are fussy about deleting or overwriting
open files. The else path of your if ( !opendir(...) ) should
closedir(DIR1). Of course, if you are just trying to check for
existence, or directoryness, there is an easier way -- if (-e
$dir ) for existence, or if (-d $dir ) for directoryness -- no
need to do a dummy open when no reading is intended.
Cheers,
Peter

Subject: Symbolic reference under Strict: any alternative?
Message-Id: <3946BB55.85AF3598@ark.ch.nospam>
Hi everybody,
When working under Strict, it's normaly not possible to make any
symbolic reference (unless you desactivate Strict..). Is there any trick
to get the value of the a variable by having its name only (e.g. with
eval)?
use Strict;
$var1='foo';
$var2='var1';
$$var2 can't be used under Strict... how to do?
(This is very useful in case of templates for example).
Thanks,
Christophe D.

If $var1 is a global (package) variable, you *could* do:
{no strict 'refs';
$var3=$$var2;
}
The block limits the scope of the relaxation.
However, if $var1 is a lexical (my) variable, you can't take a symbolic
reference to it as it won't be in the symbol table.

Hashes make more sense in the case of templates.

Try that with a 50K program that you left out a '}' in. EOF errors are no
help. :-)

I currently do this by converting Windows to UTF-8, and then UTF-8 to
Mac. Or vice versa. The reason is that UTF-8 encoding is
Unicode-compatible, and Unicode character mappings are available from
<ftp://ftp.unicode.org/Public/MAPPINGS/>. Well... you could use plain
Unicode (2 bytes per character) too, I guess.
Populating a substitution hash from the mapping files from the site
mentioned, is pretty simple, and a simple s/(PATTERN)/$subst{$1}/g will
do.
