Subject: Assoc Array in Complex Data Structure
Message-Id: <5ii8t1$hqf@netnews.upenn.edu>
I have a fairly complex data structure, included at the end of this
message. This holds scheduling data for classes -- lists of lists of
lists of lists. I'm very new to data structures of this magnitude in
Perl, and I'm finding it hard to keep track of all of the braces and
brackets. What I have now works just fine, but I'd like to make one
change:
Right now, CLASS is a list of hashes, and ID is one member of the
hash. Instead, I'd like CLASS to be an associative array of hashes,
with the value currently in ID as the key, and everything else in the
hash as the value (ie: key = scalar, value = hash). However, I'm
having trouble figuring out how to make an associative array of hashes
in the first place.
To give you a better idea, here's some code that works with the
current data structure:
| # Advance to next spot in list of classes
| $cidx = $#{$data->{CLASS}} + 1;
|
| $data->{CLASS}[$cidx]->{ID} = "$subj$num"; # <-- This is what I'd like
| $data->{CLASS}[$cidx]->{DESC} = "$desc"; # to use as the key
|
| foreach ... {
| # Advance to next spot in list of lectures
| $idx = $#{$data->{CLASS}[$cidx]->{GROUP}[$group]->{LEC}} + 1;
|
| $data->{CLASS}[$cidx]->{GROUP}[$group]->{LEC}[$idx]->{CU} = $cu;
| $data->{CLASS}[$cidx]->{GROUP}[$group]->{LEC}[$idx]->{PROF} = $prof;
| @{$data->{CLASS}[$cidx]->{GROUP}[$group]->{LEC}[$idx]->{TIMES}} = @sched;
| }
You can see how this would be improved by changing {CLASS}[$cidx] into
{CLASS}{$id} or something of the like. My primary problem is with
classes which are erroneously split into multiple pieces in the input
stream. When that happens now, I get entries with duplicate ID's. I
could search the structure for a matching ID rather than adding a new
record, but with the existence of associative arrays, that seems like
reinventing the wheel. And if nothing else, I'd really like to learn
the correct way to do this.
My data structure is below. Any help would be greatly appreciated.
Notes pointing out my insanity for creating such a monster are welcome
as well. :-) Thank you very much!
$data = {
CLASS => [ {
ID => "",
DESC => "",
GROUP => [ {
LEC => [ {
CU => 0,
PROF => "",
TIMES => [ () ]
} ],
REC => [ {
CU => 0,
PROF => "",
TIMES => [ () ]
} ],
LAB => [ {
CU => 0,
PROF => "",
TIMES => [ () ]
} ],
} ]
} ]
};

First off, I don't think that you meant /etc/passwd; /etc/hosts, maybe?
/etc/passwd shouldn't have anything to do with hostname lookups.
If Linux uses /etc/nsswitch.conf to determine name lookup order, verify
that the line beginning with "hosts:" has the keyword "dns" before the
keyword "files". This will cause name lookups to search the DNS system
for a match before referencing the /etc/hosts file when looking up a
name or address (that's how things work on a Solaris box, anyhow).
Other than that, check out your /etc/hosts file. If the host that you are
trying to look up is found in there, then my guess is that your system
won't bother to look it up using DNS.
Hope this helps :)

first off, this is a newsgroup, and the whole point of a newsgroup is

it's not compulsory for you as a single to give an answer, but the
newsgroup as a whole has some kind of obligation to answer *legitimate*
questions.
I can't understand why CGI question get answers like "this is the wrong
group and this is the answer", while mine, purely about perl OO features
I am trying to learn, was left unattended for days when anyone a little
bit more knowledgable than me could have found the answer with a single
look.

because the answer was not on the group, but by Email after I solicited
Tom personally (that's why I posted the answer). I did that because a
vague answer I had received did not clarify my situation at all.
It was not nice to involve Tom, who already does a lot for everybody
here, and I am embarassed to admit that I had to get in contact with him
privately. On the other hand I think the newsgroup sort of misbehaved.

Hi,
I am new to perl and I have a question:
I have this little counter program for my homepage, but everyone can use
it. I want to use it for one page only. How can I check that a variable
does not equal a given string?
Like :
(in Pascal)
if referer <> "http://www.hiero.daaro.com/~incognito/index.html"
then
begin
{store the hit}
end
{if not do nothing}
The source I have so far is this bit that stores the hit
<cut & paste>
open(LOG,">>$basepath$logfile");
#date&time
print LOG "$date\n";
#Remote Host
print LOG "$ENV{'REMOTE_HOST'}\n";
#Remote IP
print LOG "$ENV{'REMOTE_ADDR'}\n";
#referring page
print LOG "$ENV{'HTTP_REFERER'}\n";
#Type of Browser
print LOG "$ENV{'HTTP_USER_AGENT'}\n";
close (LOG);
</cut & paste>
The bit I am curious about is the if-it, the rest I understand I think.
Thank you!

That is an error message related to the chapter "Importing CGI methods"

The easiest solution should be to
use CGI qw(:standard);
...and &main::start_html will be defined.

Common Lisp users just don't believe in short identifiers.
They work with large libraries and very helpful interactive
development environments. Completion of names is only a keystroke
away. Macintosh Common Lisp is just fine for scripting other applications
(since it does support AppleEvents). People are using it all day for this.
Once you have to deal with libraries larger than just some GUI
stuff, then you will acknowledge descriptive names, a cool
object system, explicit datatypes and *interactive* use with
full speed of a native code Lisp compiler. You just don't
need the destinction between scripting and systems programming,
prototyping and delivery. Things start to become unified.

CS graduates make competent software engineers..... yeah right.
Studies have shown lobotimized rats make better programmers than CS
graduates. But seriously, Computer Science is not doing a good job of
training software engineers. I agree that production oriented
languages should be design to be simple, promote good "programming in
the large" software engineering and be easily understandable in a
human understanding sense (as opposed to some CS theoretic
masturbation sense) for both CS and non-CS graduates.

I believe certain languages will higher training costs than other
languages. If I made a OO/functional/logical/constraint
based/procedural/dynamic-static-inferenced typed language (probably
based on analogies with the string theory of quantum gravity), then
the training time will probably be huge, especially if the traines are
not exactly "Marilyn Vos Savants". If the language doesn't really
give you any big gains over let say Eiffel, then whats the point?
C/C++ is complex and is hard to learn by the average Joe programmer,
but this gives no credence to language designs that remove some of
C/C++'s complexities but then add a whole bunch of other complex
features. I am sick of bloated languages, but thats all thats
possible due to standards committees, marketing pressures and
"bizarre/fad concept of the day" oriented academics.

For many application areas, parallel programming is not trivial in any language.

There seems to be a bit of confusion here. Dynamic typing !=
no interface declaration/checking. See ObjC as an example.

Uhm, historical facts don't change. Or aren't Ritchie and Thompson
no longer the original authors of Unix anymore? Maybe nowadays
Unix was designed by Microsoft?

Administrivia:
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.
