Script within a script
Is it possible to execute a perl script within another perl script? I have advertisements on many of my pages of my site that are randomly picked using a random ad script.

Clearing Arrays
Hi I do not want to continue this thread to bag other users, but I do have a number or perl books and it did take me some time to find out how to clear an array. From the replies I got (and I thank those who did reply) confirmed I was using ' @array=()' correctly. In the end, I found the problem that was giving me grief. This is a good forum to subscribe to. I save all my emails into a database (1,000s so far) so I can search back if I have a problem. I did not find any reference to clearing arrays, hence my question to this forum.

As your system and objects, etc. become more complex there is a good chance you are going to find that using a flat list as method parameter passing is a nightmare, you may want to consider passing arguments in a named list manner, so that they can be unordered, optional, etc. This adds to the complexity of argument verification but in the long run adds flexibility to the interface. Some examples: my $object = new Class (value 1, value 2, value 3); In the above the new constructor takes three values that *must* be in the proper order (unless their type can be gleaned in other ways such as with ref or isa) and must all exist. For instance if you didn't need nor have 'value 2' you still must specify a place holder, like: my $object = new Class (value 1, undef, value 3); etc. Which makes the interface less flexible in the future, and harder to remember how it may(must) be used. I tend to advocate named parameter passing such as, my $object = new Class (key1 = value 1, key2 = value 2, key3 = value 3); Then when value 2 is needed or isn't known simply drop the key/value pair and nothing else in the method should need changing, assuming it wasn't required before. Certainly there are times when an interface needs to be simple and isn't likely to expand greatly, or a particular argument must *always* be provided, in which case this may be overkill but I thought I would mention it. Using named parameters may also make it easier to pass lists, which need to be passed as references, in which case explicitly naming them may help on both sides of the interface. As a side note to the list, I posted a message to Gary (trying to prevent the previous thread from becoming cluttered, which it has now anyways :-)) stating that I think his application (aside from the real time need) is perfectly suited for experiments into POE.

Unfortunately, this doesn't work. As Randal already said, it's not
possible to do both. You either print a page, or redirect to another
page. Here's a quote from CGI.pm POD:

The redirect() function redirects the browser to a different

The fetchrow_array method returns a list of data. In the first part of the 'if'
statement you're throwing that list away - nothing's being assigned to $_. In the
second part you're copying the list into array @row, so it should work fine.
Dereferencing $_ as an array with @$_ will work only if $_ holds an array
reference. You could rewrite the first loop as
while ($_ = $sel-fetchrow_arrayref) {
print OUTPUT '';
print OUTPUT join ',', map {$_||0} @$_;
print OUTPUT '',\n;
}
which will work because the fetchrow_arrayref method returns an array reference
and it's being stored in $_. Using $_ is only useful if there are several
operations to be done on the value that can take $_ as a default parameter. In
this case you have no such operations and you would be better off writing
while (my $row = $sel-fetchrow_arrayref) {
print OUTPUT '';
print OUTPUT join ',', map {$_||0} @$row;
print OUTPUT '',\n;
}

I still think that it will be a bit OTT for my project. It is pretty complicated, the tough part is that so is your project ;-)! As the others have expressed. I am concerned (take that loosely) that, while your attempts to learn OOP in this context are certainly worthwhile and giving you progress, the OOP may be hiding the complicated part of your problem that is yet to come which has been mentioned briefly before. In other words how do you keep the parts of the system running in a constant nature while attempting to receive inputs from external sources in possibly multiple ways. The problem I foresee is that you have multiple objects that are all possibly (usually?) doing something independently but also must detect and handle signals from other objects in some unscheduled manner which is fine to say, but the problem becomes that a single Perl process *blocks* (usually), which essentially means your objects can't work independently and concurrently. In more concrete terms, you have to have a way to have a train move along a track, have a signal box receiving signals, having a trainset manager (can't remember the name you gave it) inputting data (aka using the controls), having the controls waiting for inputs and handling them, etc. *at the same time* all the while with some way to get the various parts talking while they work. The problem becomes how to do this, how to prevent the blocking, three options come to mind (for me) threads, forked separate processes (using IPC or shared memory (yikes)), or some type of time slicing aka POE, Select, or Loop (group have I missed any?). I am curious if the discussion about the owner and managing all of those tasks is the reason why the object structure hasn't been as obvious as it should. Essentially this is the jump that must be made from simple scripts to long running programs, essentially a server, where rather than serving data of some sort you are really serving trainset events (which of course is just data), then a client plugs in to control those events. I am thinking that you can resolve your object system and make it seem like it will work, but when you go to flip the on switch it is just going to sit there because how to get the different parts moving hasn't been worked out fully in the design, that or you will have a series of events that must happen in the essentially in the same order at the same time, which is hardly like the real life system you are trying to emulate. But then I could just be off my rocker in the end if I am not loco, POE is going to be one easy way to get this type of system running. The idea of named parameters is worth considering as my project and therefore the methods is starting to get far more comprehensive and complex.

While this is good documentation and in the end does the right thing,
the part I don't like about it is when it reads:
You should not print out a header *as well*.
The problem is that, as well, implies that a header hasn't been
printed, but the fact is that the redirect is a header, or more
precisely is a line of the overall header, and one that specifically (at
least by today's browsers and the HTTP protocol itself) indicates that
there won't be a content type and data coming. So it isn't that you
can't print multiple headers, but that the client only respects the
first, so you can't print one, have it interpreted, then print another,
and have it interpreted as well. The difficult part is that the docs
are written by people who understand the protocol, and back in the day
most developers understood the protocol because HTTP was new and the
client/server model was older so the statement should be obvious (to the
point of not needing it), now days many web developers don't even know
that there is a protocol, let alone anything specific about it, so what
shouldn't need to be there becomes obvious, but the fact that it needs
to be there indicates that there needs to be more description along with
it...

redirect() does a header like header(), the first header
that gets sent is the header, the rest is content, even if
The contetn looks just like a header.
If you run that in a browser you'll probably see Location: /thanks.html
in your screen. Since that is content for the header() you did above it.
Make sense? I also remember hearing it's a better idea to use absolute
url's in your Location header.

RE: decoding a base64 file?
Hello folks,
If I encode a file with MIME::Base64 with the following
script, encode_base64.pl. The
question is; how do I decode the file? I use the following
script, decode_base64.pl to
decode back to the original source but that did not work.
Thank you...
[snip]
while (read(FILE_R, $buf, 60*57 )) {
$encoded = MIME::Base64::decode($buf);
print FILE_W $encoded ;
}
Try decodeing the entire encoded data instead of a line at a time.

RE: redirect with cgi.pm

Re: == eq gt
--As off Wednesday, January 14, 2004 10:34 AM -0500, Paul Kraus is alleged to have said: I understand that the eq and gt are for string comparisons but why not just use the mathematical ones of == or . This goes for functions open ... or compared to open .. || --As for the rest, it is mine. Because a string isn't a number. Sure, you can treat a string as a number, or a series of numbers, based on the ASCII values. But that leads to weirdness and confusion. For example: The best numeric representation of a string is a _series_ of (ASCII/UTF8/etc) numbers. The numeric comparison operators work on one number on each side. So, how do you convert a string to a single number? Do you add the array together, or work on the first only, or something else? Ok, so your next objection is that the operator should just know which you mean (numeric or string) and compare using the correct metric. Except, on occasion, you _want_ to compare two strings as if they were numbers. Perl will let you do that. (Even if 'use warnings' will tell you not to.) As for or vs ||... That is more of a precedence issue at the moment. Note that open ... or would _not_ do the same as open ... ||: The latter would do the comparison before the open. This could be useful: you could make the choice of what to open right then. But it wouldn't be the open ... or die trick we all know and love: for that the open has to be tried first. In conclusion, Perl has seeming duplicates often because they aren't duplicates, just near-duplicates. Sure, the language could get by with just one. It would just be more work for the programmers.

Re: check whether file is ascii or ebcdic

If you were referring to strict ASCII, the 8th bit would be clear and so, assuming you are talking about text files, you would look to see whether the 8th bit was used much, because most printable characters in EBCDIC have the 8th bit set. However, the picture is a bit muddied by the fact that there are character set extensions to ASCII that set the 8th bit. So the mere presence of a set 8th bit doesn't rule out ASCII. I suggest you do some tests on samples of the kinds of files you'll be dealing with and print out the percentage of characters they contain that has the 8th bit set, and look at the ASCII vs EBCDIC ones.

First of all, what is that module?
It is the very module you were using in this moment (bundled with its
prerequisites, hence it's a 'bundle'). I'd always keep it up-to-date so
it's a good idea to do a 'install Bundle::CPAN'.
Second of, I have noticed that it installed Readline, so my CPAN shell

I don't know. It's certainly not related to Perl in any way.
Could anyone guide me to a document talking about .pm's? I didn't think

Can you be more specific? Those files are Perl modules and thus they are
written in Perl (they are usually the meat of any stuff you download
from the CPAN). That means that these never need to be compiled. Around
95% of the CPAN will not require any compilation. Perl modules written
in (or containing) C need a C-compiler.
As for 'make', this is not doing the compilation, if any. 'make'
processes a Makefile that contains certain rules. It is most often used
for building and installing a piece of software. Most of the modules on
the CPAN contain a file 'Makefile.PL' that - when run - produces a file
called 'Makefile'. After you have that, you can continue with
make
make test
make install
The first line will do any necessary preparations (this could also be
compiling C code when the module contains bits of it). The second line
triggers the rule 'test' which will run any tests enclosed in the
package. The last one finally installs the module.
When you use the cpan shell, all the above happens behind the scenes.
More precisely, in this order:
perl Makefile.PL
make
make test
make install

Because perl is expecting an array (@_) to be returned and you are
putting it into a scalar.

The split() function returns a list, not a scalar. When you tried to assign it to a

RE: Apel of VIM was Emacs Wizards
Incidently, emacs has a 'dired mode' (directory editor) which is very nice... much like the old 'list' shareware in DOS land of the dark past you can bring up a list of files (like 'ls -l'), then view and selectively execute or delete all that you mark. It's very nice, and it can also be used when accessing remote servers. Not to mention it allows syntax highlighting. As driex pointed out, it is the start-up time that is preferred in vi/vim. But again, a true emacs die-hard never exits the editor and does all his/her tasks inside the of it. Not to mention, the learning curve for emacs is horrific. JW ~ Bradley A.

strange sort order
Hello,
I do not have access to the sort operation. All I have is a file that is
sorted but I don't know exactly the mechanism by which it was sorted.
What I am trying to do is write a comparison function--given any two
lines in this file, return -1, 0, 1 as perl's cmp function does. I don't
have to sort the whole file, I just need to be able to tell, given two
lines, which should come before the other in the sorted ordering. (I
need this to do a binary search over the file, which is quite large).
Anyhow, I'm posting the function I wrote to do this. It is quite long
and to me is naive. It is also pretty slow. I have tested function in a
larger script that I wrote. As a method of comparison, the script takes
23 sec to run over a 500k file using my function. When I substituted
perl's cmp for my function, the same script ran in 12 sec. I'd really
like to get this running more quickly as I have to run my script on
files MUCH larger than 500k.
I'm thinking the way the file is sorted is something simple, yet
something I don't recgonize! As a result, you'll see that my method is
probably very over-complicated.
I have also posted some more data that is representative of what I have
to work with. Both the comparison function I'm using and the sample data
are attached if anyone wants to check it out. I appreicate any suggestions.

I have a file that appears to be somewhat sorted, but is not sorted

this sorted file, any tips on doing that in the most efficient way
possible would be helpful. Thanks.
Examples. I give some sets of strings to indicate which comes before the
other in the sorted file. The first one in each pair is less than the
second. Each set is independent of the others. set x doesnt necessarily
come before set y in the file if x y.
Set 1:
0-CELEBRITY-0
0-CELEBRITY
Set 2:
0-0-7
0-0
Set 3:
000-AAA
000
Set 4:
000
Set 5:
0908
09088122595
09088122595
0909-114
We could make guesses as to the sort algorithm, but there is very little data
here to go on. If you sort stringwise on the first fragment of the string up to
the dash then you will get exactly this order. But several strings have the same
first fragment (all of Set 1 and Set 2, for instance, start with the value '0').
Do you have access to the sort operation so that you can sort arbitrary data?
This can be decided properly only by seeing how contrived test data is sorted.

Set 4 was: 000 and yes, that appears in the file in that order. Also, the sample data I gave in the last email exists as listed as well. So in set 4, we'd scan the first 3 corresponding characters but the first would run out. If we treated it as a null, which has ASCII value = 0, then 000 would come before and we have the right ordering. However, the last two lines int he sample file i gave are: ABC-MARKET.ABC-MARKET ABC-MARKET Here, the first 10 characters correspond but then the second string runs out. Using our rule, we'd order ABC-MARKET before ABC-MARKET.ABC-MARKET, which is wrong. I guess I could try following that rule, but if the character position in the longer string that corresponds to the first position in the shorter string where there is no character is a - or a ., then the longer string is less. Just a thought. I'll have to check out the data more and try it out.

--As for the rest, it is mine.
You actually have two seperate problems here... First off, you
aren't reading more than one line at a time, since the readline
operator stops at a newline. Then, a regrex normally stops at a
newline too, unless you specifically tell it to continue past those.
( The 'm' operator, mentioned in other posts.)
The first problem is actually the bigger one: The obvious solution of
reading the whole file to an array/scalar first has preformance
problems, especially with large files. (Worst case: A file bigger
than avalible memory...)
Kent's solution neatly sidesteps that, if you don't care that the
program has no idea of which records go together. (His solution just
prints each record line, assuming they are in the correct order
already.) Otherwise you are going to need some sort of temporary
storage where you put the records back together, or read the file in
chunks.

Here, the first 10 characters correspond but then the second string runs

position in the shorter string where there is no character is a - or a

check out the data more and try it out.

Since you've already been shown the super easy way, I'll dare to be a
little different:
#!/usr/bin/perl
use strict;
use warnings;
$/ = '';# enter paragraph mode
while () { # call with: perl script_name file1
my %contact = map { /^(\w+):\s*(.+)$/ } split /\n/, $_;
print $_: $contact{$_}\n foreach qw(Name City State);
print \n
}
__END__
The first way your were shown is probably a little easier, but this
method is probably better if you want to do anything more complicated
than simple printing, since you have the whole hash to play with. It's
a different way of thinking about the problem at least.
Good luck.

If this is a 'real' sort operation this isn't necessary, and
shouldn't even work. Perl will do this for you.
my $asciiDASH = 45;
my $asciiDOT = 46;
These are legitimate constants. Declare them as such, outside of the
subroutine. Then these assignments will only happen once, at compile
time. (Instead of _every_ time the sort calls this routine.)
my @a = unpack(C*, $a);
my @b = unpack(C*, $b);
This can also be done with a:
my @a = split //, $a; # (That is a null pattern.)
I'm not sure if split or unpack is faster, I'll have to benchmark in
the morning.

Thanks for posting this. My first thought was a hash, thinking in terms
of key-item but I couldn't figure out how to populate the hash. This
code will give me something to analyze. The map function looks like
voodoo to me:)

RE: multiline matching
Just for the sake of showing another solution (even though I'm not doing any
multi-line matching), how about:
##
use strict;
use warnings;
open(INFILE,myfile.txt) || die Couldn't open myfile.txt for writing!\n;
while(INFILE){
my %person;
$person{name} = $_;
$person{city} = INFILE;
$person{state} = INFILE;
$person{address} = INFILE;
$person{age} = INFILE;
#do whatever you want with your lines here
}
##
This gets you the whole record in a hash that goes out of scope after each record so
that you don't have to slurp the file, but you have the flexibility to do whatever you
want with the data. You can replace the city and state lines with just INFILE; on
its own line if you don't need the data for anything. Of course I'm assuming the file
is in order, but I figured that was implied by the three consecutive lines part of
your question.
