Wrong again.
Scientific method does not and never did require that theories
be formulated by observers in the field. In fact, many discoveries
were made by sharp minds who had never even visited the trenches.
It should be obvious that the authority in any given subject is
derived solely from one's understanding of that subject, rather
than from how many years one has spent doing this or that.

Nope, however it often takes the intake of spirits to consult
the perl source. :-)

Which is basically what my piezo perl internals was pointing
out.
Instead of exists($foo{bar}{baz}) doing (hv_fetch() || newHV()), etc
all the way down the tree until it can finally do pp_exists() on
"baz", why can't the first hv_fetch() that fails result in exists()
bailing out false?
It seems to me this would be *faster* for all cases. Why? If the
tree is complete and we can do pp_exists() on the final element, we
lose nothing (we have to fetch the entire tree anyway, which implies
a test of some kind or another (hv_fetch() returning false, I
think)). If the tree is not complete, we basically do the same
operation but we can bail out sooner.
Along similar (ok, a bit twisted:-) lines of logic, should:
-f "/path/to/some/file.txt"
First create the full directory structure, /path/to/some/, if it
does not exist? God I hope not. :-)
Note however, that I'm not speeking of assignment here, only the
special case of exists(). Indeed, $foo{bar}{baz} = "dog"; should
of course work as it currently does. I can not however, see a
single reason why an exists() test should be creating anything.
Not creating more structures is a primary (but not only, I'll
admit) reason for having exists() in the first place.

Subject: Manipulating Single lines in file...
Message-Id: <01bde761$72295fc0$4b8c41d8@dwalla.pacifier.com>
I am working on a glossary script and am almost complete; all i have left
is the admin script, which has been causing me some troubles. I have 26
files (one for each letter in the alphabet), in which the words and their
definitions are stored, so each file looks something like this:
word|number_assigned_2_word|definition
word2|another_number|definition
etc.
I have gotten as far as making the admin script that displays the word that
you wish to edit or delete, but i don't know how to manipulate single lines
in a file. Is it possible to open the desired file and delete the line i
wish to delete so i can replace it with the new, updated line (or not even
replace it if i just want to delete the record)?
If my previous paragraphs didn't make any sense, pretty much what i want to
know is how to delete individual lines from a file. If you can provide
information that would help me, it would be greatly appreciated. Thank
you.

:

Umm, not quite correct. This is an anonymous function, which is
only part of what a lambda function is. Indeed, it is not even
the most important or most interesting part.
: For example in perl I can go,
:
: $var = sub {
: $x =shift;
: $y =shift;
: return $x+$y;
: }
This is a function pointer to an anonymous function. A lambda style
function is more powerful as in addition to this aspect, it also holds
the state at the time it was defined. Perl example:
sub foo {
my $x = shift;
return sub {
return $x * 10;
};
}
my $this = foo(5);
my $that = foo(10);
print $this->(), "\n";
print $that->(), "\n";
## Prints:
## 50
## 100
Simply, the state of $x at the time the anonymous function was built
is stored as now an intrinsic aspect of the anonymous function.
Indeed, it is even similar to a field of an object. The paradigm
here however is reversed from traditional OO in that instead of the
data knowing how to do work on itself (an "object" of data with
methods), the work knows what data to work on.
Java can not do this. Not with interfaces, inner classes, or
anything else (well, except for JPL <evil grin>).
Would one build an entire system from lambda functions? Probably
not, however I have yet to see anyone, any language, or any other
methodology match them for call back operators, dynamic dispatch
tables, and similar highly dynamic operations. This is why even
Python (if memory serves me) has support for them.
Now for George, please show us how this aspect of lambda functions
(*not* function/method pointers) can be replicated in an OO framework.

A lambda function and a closure are the same.
An anonymous function is simply a function without a name. A
function pointer is the address of a function that may or may
not have a name.
Normal function:
sub foo { return "foo" }
Anonymous function:
my $foo = sub { return "foo" }
Function pointers to named functions:
my $foo = \&foo; ## "Hard" (ie address) reference/pointer
my $foo = "foo"; ## "Soft" (ie, by name) reference/pointer
Function pointer to an anonymous function:
my $foo = sub { return "foo" }

Subject: Perl with use/require doesn't work under cron
Message-Id: <6ucdtf$1n$1@nnrp1.dejanews.com>
Hi,
I have a perl script that that uses "use myPackage;". The script works fine
from the command line (AIX 4.1.4). When I try and run the script as a cron
job, the script never runs. I tested this by using some print statements to
a file and they never show up when under cron but work fine when run from
the command line.
I changed my script to use "require" and that did not work either from cron.
Again it worked fine from the command line.
If I take out the "use" and "require" statements from the script - then it
works fine from the command line and from cron.
The packages that I am using are some of my own located in the same
directory as the script.
Any ideas ? Has anyone encountered this problem ?
Thanks in advance.

I'm still learning. I wrote my first perl script three years ago. Since then
I've been through every other language until I was tasked to kick out some
killer perl scripts. When I'm done I'll never go back to any of the others.

Those as well, including Perl by Example (Redbook),
Advanced Perl, Web Client programming, Lincoln Stein's CGI.pm,
But mainly I have learned, and am still learning, from others
- Other peoples code (good and bad) and from people here
on comp.lang.perl.misc.
Also, I find that I gain the most insight from doing examples
and testing out ideas. Some things work, some don't; but
all in all I find find Perl most helpful :]
And I admit that I should read the 'included docs' more, but
some sections I just can't stomach, sorry...

I've been trying to find some way to pull this off and I'm hoping that
someone here has gotten it to work.
I have a form on a website that I'm designing for a university group
that hires students to help other students improve writing skills. There
is an online application for interested students to sign up. Part of the
application process is the submission of two writing samples. I wrote a
CGI script in Perl 5 that calls sendmail and sends the submission to the
responsible person. I would also like to be able to offer the ability
for the student to submit their writing samples online as well, using
the file upload feature of Netscape. I would then want the submitted
files to be included as attachments when sendmail sends the data to the
recipient. Does anybody know if this is possible? I know how to write
the HTML for the form, however, I am unclear of the coding on the Perl
side and sendmail attachments. Any help or advice would be appreciated.

One might note that the original problem specification was explicitly
to include commenting the regex. I guess the only way that CPerl
meets this spec is by noting that the spec doesn't say how much
commenting.
I guess that I would use CPerl in emacs to indent my code, wheras I
might use regdecl to save the hassle of poring over regex doc to
decode some obtuse regex that uses features I haven't seen before...
Where do I get CPerl?

Message-Id: <3609BFFD.29AFA9E5@OBJS.com>
I am trying to simply call cat (win95) with three vars, but they are treated as literals...
Why?
E.g.
system ( 'cat i:\foo.txt $_ > $mytmpfile');
Doing a print works:
print $_ ;
or
print "Processing file: $_" ;
so, why is the variable handled like a literal in the system call??????
Were's this darn oddity documented in "Programming Perl"?
Thanks SO much (in advance)!
Paul.
[please respond directly to me.]
p.s.[I am using File::Find, and all I want to do is insert a few lines at the top of every
file in a directory (including subdirs) -- the file traversing works, just not the insertion.]

Lynx and ncftp are just command line operations - not much to go wrong.
Normal ftp needs to use ~.netrc or a chat on a pipe so it is more
fragile under program control.

Administrivia:
Special notice: in a few days, the new group comp.lang.perl.moderated
should be formed. I would rather not support two different groups, and I
know of no other plans to create a digested moderated group. This leaves
me with two options: 1) keep on with this group 2) change to the
moderated one.
If you have opinions on this, send them to
perl-users-request@ruby.oce.orst.edu.
The Perl-Users Digest is a retransmission of the USENET newsgroup
comp.lang.perl.misc. For subscription or unsubscription requests, send
the single line:
subscribe perl-users
or:
unsubscribe perl-users
to almanac@ruby.oce.orst.edu.
To submit articles to comp.lang.perl.misc (and this Digest), send your
article to perl-users@ruby.oce.orst.edu.
To submit articles to comp.lang.perl.announce, send your article to
clpa@perl.com.
To request back copies (available for a week or so), send your request
to almanac@ruby.oce.orst.edu with the command "send perl-users x.y",
where x is the volume number and y is the issue number.
The Meta-FAQ, an article containing information about the FAQ, is
available by requesting "send perl-users meta-faq". The real FAQ, as it
appeared last in the newsgroup, can be retrieved with the request "send
perl-users FAQ". Due to their sizes, neither the Meta-FAQ nor the FAQ
are included in the digest.
The "mini-FAQ", which is an updated version of the Meta-FAQ, is
available by requesting "send perl-users mini-faq". It appears twice
weekly in the group, but is not distributed in the digest.
For other requests pertaining to the digest, send mail to
perl-users-request@ruby.oce.orst.edu. Do not waste your time or mine
sending perl questions to the -request address, I don't have time to
answer them even if I did know the answer.
