RE: How do I document my perl code?
POD - Plain Old Documentation You'll find this in the perl doc as perlpod basically you use the = in column one with a keyword. Perl parser ignores anything betweeen a beginning = and the final marker =cut. Typically its: =pod =head1 DESCRIPTION blah, blah, blah... =cut code.. Other notes: 1. the = =cut markers can also be used to comment out code rather than each line as in: =comment code.. =cut 2.

Printing a multipart HTML output
Hi all, Please tell me how can I create a multipart html file that includes html text and images. I know that Mime::Lite can create such a thing for sending an email with attachments, but I don't know if it is possible to use it for creating common HTML pages with multipart content. Thank you.

Re: Printing a multipart HTML output
Hi all, Please tell me how can I create a multipart html file that includes html text and images. I know that Mime::Lite can create such a thing for sending an email with attachments, but I don't know if it is possible to use it for creating common HTML pages with multipart content. I was not aware that this was even possible. It does appear that some browsers, specifically in the Netscape class could handle this at least once upon a time. I found a link through google to chapter 13 of the definitive HTML book from ORA (illegal copyright violation so I will not provide it), that talks about how to do this, specifically in an HTTP push application (like streaming media, etc.) so apparently it can be done. This is going to be very, very browser implementation specific I imagine, because the browser has to know how to deal with multipart data transmissions, etc. but assuming your target app can handle it then it appears to work almost exactly as MIME does in e-mail. Aka you specify a content-type of multipart/*, with a boundary string, then just print your multiple parts separated by the boundary. Having said that you might be able to coerce MIME::Lite into doing this, though it might be overkill, since you may not have to deal with encoding, etc. since it isn't mail going through an intermediary. Either way you should look into some of the server-push applications available and see what they do. Of course, not sure why you would want to do this with text and images anyways, why not just serve up a normal img tag?

Re: POST and GET and CGI.pm
Greetings, While reading some of the Perl newsgroups, I've seen a few examples of people getting CGI parameters by either parsing the query-string (for GETs) or reading in some of the content (for POSTs). I've been working with CGI (using Perl) for a little while now and I've always used the param() method in CGI.pm and it is working for both GETs and POSTs. I'm wondering if I'm missing something and if there are times when using the CGI.pm param() method is not advised. Thanks. You're not the one missing out. 'param' specifically isn't always the best way, for instance sometimes I like to pull them all at once with the 'Vars' method. Or in the case of file uploads I generally use the newer upload interface methods. Point being, you should rarely if ever need to parse the query string/post yourself. To me, using the CGI module would never be the wrong way to do it, whereas the other would be. mod_perl not in consideration at this point, aka there is the Apache::Request (I think?) for that, etc. http://danconia.org -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/ http://learn.perl.org/first-response
help with adjusting log file data?
Hi guys,
Needing a little help with adjusting the data a log file reads to.
It goes like this currently
@env_vars = keys(%ENV);
foreach $variable (@env_vars)
{
$log_entry .=$ENV{$variable}\|;
}
I am wanting to change this to include $http_referrer
So,I am presuming that I should be doing this:
foreach $variable (@env_vars)
{
$log_entry .=$ENV{'http_referrer}\|$ENV{$variable}\|;
}
Is this correct??
thanks in advance

There is no need to escape '|' in a double quoted string.
This is equivalent to the loop, though I don't know why the
extra '|' at the end would be wanted.
my $log_entry = ( join '|', values %ENV ) . '|';
: I am wanting to change this to include $http_referrer
If http_referer has anything in it it will be included
already.
: So,I am presuming that I should be doing this:

There is a typo in there.
$log_entry .=$ENV{http_referrer}|$ENV{$variable}|;
}
: Is this correct??
My first thought was: What happened when you tried it? Then
I wondered what you meant by correct. In my mind, even after
fixing the typo this is incorrect.
You are defining every other pipe separated field with the
referrer. At some point, assuming the referrer is defined, there
may be three such fields in a row. I don't think that is
really what you want. This looks more like it:
my $log_entry = join '|', values %ENV );
The next thing I wondered was whether you were aware that
newlines are embedded in at least one Apache field
('SERVER_SIGNATURE'), thus $log_entry won't be one line in
the log and won't be able to be retrieved as one line.
Here's a script that generates $log_entry with newlines
(\n) instead of pipes ('|').
#!/usr/bin/perl
use strict;
use warnings;
use CGI;
my $q = CGI-new();
# bold the referrer if present
$ENV{http_referer} = $q-b( $ENV{http_referer} )
if exists $ENV{http_referer};
my $log_entry = join \n, values %ENV;
print
$q-header(),
$q-start_html(),
$q-pre(
qq|Referrer (if any): $ENV{http_referer}\n|,
$log_entry,
),
$q-br(),
$q-a( { href = $q-url() }, 'again' );
$q-end_html();
__END__
Type the url into the browser address bar the first time.
The second time, click the again link. When I tried it on my
local system (Apache on Windows) I got a referrer only after
clicking the link.
Notice that the referrer is included in the list when it
is defined.

Hi There,

I am writing one script which displays one report to user and then

User need to see complete file. To solve this, I thought I can call
`more in the script and continue.
But looks loke it is not possible.
You didn't post your script, so I can only guess.
You can't use backticks, since they capture the output. If more is writing
to a non-tty (because you're capturing the output), it obviously has no way
to pause at a screenful, so it just passes the entire input to the output.
You need to use system() instead.
Also, it's customary to respect $ENV{PAGER}. I have my pager set to less,
for example.
Read perldoc perlopentut and search for PAGER to see an example of how to
do this kind of thing.

Re: if -s clause
I have tried all three methods if -s OUT, if -f $filename and if -s
@arrayname with no evail.
I did make a test.pl file so that I am just testing whether the file is
greater than 0 bytes. Here is the code.
autoflush is turned on. Is this the correct spot for this?
Is it this tedious to test if a file is greater than 0 bytes
I thought perl is supposed to be this great language for UNIX and C
people???

Well theoretically that might work since the def in the docs indicates a
filehandle is possible. I am wondering if maybe it is because your
output does not contain a new line and is buffered. One of the gurus
with internals knowledge would be better suited to answer that. You
might try turning on autoflush for the handle before printing it, or
alternatively as I already suggested close the filehandle, which will
force the flush to occur (and conveniently force you to test the file
rather than the handle which is my next suggestion). This is probably
the copout approach, but to me the easiest least worrisome approach. No
guesses needed.
Please excuse my indentation as I cut and pasted it. My goal is to send
a mail
message using MIME:Lite if the file is greater than 0 bytes else just
touch a file.
The reason for opening the RUNFILE is b/c I wanted to create a file to
verify
there the if -s clase produced no output. In other words, there is no
data
being appended to $foreigntapes variable.
thank you!

Re: Yet Another Regex Problem
On Jun 8, Francesco del Vecchio said:
I have to find URLs in a text file (so, cannot use LWP or HTML parser)
I'm curious why you can't use a module to extract URLs, but I'll continue
anyway.
/(http.:\/\/.*\s)/
That regex is broken in a few ways. First, it does NOT match 'http:', it
only matches 'http_:', where there is some character between the p and the
colon. Second, the .* in it is greedy (it matches as much as it can).
Third, it requires your URL to be followed by a space, which won't always
be the case.
try to click here http://www.yahoo.com or there http://www.google.com;
I would suggest trying:
@urls = $string =~ m{(https?://\S+)}g;
Using \S+ makes it match one or more non-whitespace characters. The only
problem with this is that if there happens to be punctuation after the
URL, it'll get included. An example is this:
Go to http://www.yahoo.com, and you'll see what I mean.
That will match `http://www.yahoo.com,' (including the comma).

autoflush is turned on. Is this the correct spot for this?
1. Autoflush is not turned on for the handle OUT. To do that, you would
need
to use:
my $svsel = select; select OUT; $| = 1;
or, better yet:
use IO::Handle;
OUT-autoflush(1);
2. Because of buffering, even though you have printed to OUT, the data has
not actually been written to disk yet (still in the stdio buffers), so
3. -s OUT returns 0 (which is true)
The proper test for your program is
if (@ftapes)
This evaluates the array in boolean (scalar) context, which gives the
number
of elements in the array. If the array is not empty, the test is true,
regardless of what's going on with the file.

Nope. You are testing, and the file is 0 bytes.

Re: use lib(''); Apache httpd.conf

Subject: XML::DOM::Parser question !
All,
I am trying to parse a XML file and change an element value.
Below is code of mine where I am doing this. However, setAttribute doesn't
work and it doesn't give any error message too.
I spent enough time and doesn't make sense to me. I get right value using
getAttribute('value).
XML file is also pasted at the end of this mail. Any help or pointer is
greatly appreciated.
Any suggestions in writing better code for this task is also appreciated.
Thank you,
Ravi.

Retrieving Cookie from header
Folks:
I am using the Net::HTTP package in building a small http client. I am
trying to reuse an existing mechanism to talk to a db service through a
servlet rather than code a new application in perl.
Since I need to issue several http GET requests, cookies are used to
keep session state. The problem is that the Net::HTTP package does not
expose the cookie.
Here is the perl http client code:
use Net::HTTP;
$product_id = $ARGV[0];
$doc_title = $ARGV[1];
$hname = $ARGV[2];
my $buf;
#log into the host
print SENDING login command\n;
my $s = Net::HTTP-new(Host = $hname, keep_alive = TRUE) || die $@;
$login_request = /XXX/home.jsp?NT_ID=ntid;
$s-write_request(GET = $login_request, 'User-Agent' =
Mozilla/5.0);
($code, $mess, %h) = $s-read_response_headers;
print LOGIN CODE: , $code, \nMESS , $mess, \nh , %h,\n;
#read login response page
print READING login request\n;
while (1) {
my $n = $s-read_entity_body($buf, 4096);
last unless $n;
#print $buf;
}
-
The line ($code, $mess, %h) = $s-read_response_headers; returns some
header info but not access to the cookie. I believe the cookie is
embedeed in the %h hash. Does anyone have any ideas?

Exception Handling - Professionally
Greetings, For you professional Perl programmers: how do you approach exception-handling in the your world? I know there are a lot of ways Perl gives us to do this: basic 'die', eval'ing blocks of code and the Exception.pm module but is there a standard in the real world for handling exceptions? If I was assigned to modify some existing Perl code, what type of x-handling should I expect to see?

Greetings, For you professional Perl programmers: how do you approach exception-handling in the your world? I know there are a lot of ways Perl gives us to do this: basic 'die', eval'ing blocks of code and the Exception.pm module but is there a standard in the real world for handling exceptions? In my world, and a scary place it tis', I use a home grown object and just throw it as a return value. Subs generally then return either undef or the exception, or in the case I need a return value back I just check that return value to see if it is an instance of my exception object type. At the time, I was weary of using the die/eval model, if I had it to do over again (aka I will probably switch in the future) I would probably use a combination of the two since die/eval allows you to throw objects. perldoc Carp Might also be a useful read. If I was assigned to modify some existing Perl code, what type of x-handling should I expect to see? This is a trick question right? From the code I have seen/inherited I would have to answer: None. ;-) Being that this is a TMTOWTDI world I would imagine code you inherit could deal in multiple types of exception/error handling, especially depending on how many CPAN modules it might use.

Glossary
I'm in the process of learning perl (hmm - right at the beginning of this process), and I'm having great difficulty working my way through the man pages. I'm a Windows user and perl is the first language I'm learning, so *everything* is new to me. I am also having to get to grips with using my shell account which is just adding to the difficulties. What would really make my life easier right now is a glossary of programming specific terms so that I'm not struggling to find meanings for the terminology used in some of the man pages (specifically I'm trying to work my way through man screen) every other word. Does such a glossary exist? I'm aware of the Jargon Files and I'm aware that many of these terms have man pages of their own (but my entire reason for reading man screen is to learn how to have different windows open with different things going on in each window!).

Wiggings,
I should of been more clear. It does work, but does not

properly.
C:\xml_parseperl -MXML::Simple -e print $XML::Simple::VERSION
2.12
That helps. I am assuming you are talking about how it is folding
the
single tags into attributes. This seems kind of contrived but I
believe
the following produces the same structure (aka out of order but
that
isn't strict),
#!/usr/local/bin/perl
use strict;
use warnings;
use XML::Simple;
use Data::Dumper;
my $ref = XMLin('./NMS.xml',
ForceArray = [
'itemList','menu','startPage','display','sortby','define','item','a','page'
],
KeyAttr = [],
) or die $!\n;
#print Dumper($ref);
print XMLout($ref, XMLDecl = 1, RootName = 'root', NoAttr = 1);
exit;
The main changes are the list I had to pass to ForceArray, turning
off
the KeyAttr default list, not keeping the root element, but then
also
setting what the root element string should be, and finally
telling it
that none of the tags should be folded into attributes on output.
I haven't come up with a good way to figure all of this out yet,
usually
I just do a lot of guess and test until it produces exactly what I
want.
Generally messing with ForceArray and KeyAttr has gotten me where
I
needed to go. You might re-examine the docs on these particular
attributes.
Helps?

RE: Query Oracle, show results (need help!!)
I think you should turn on errors... by debault DBI will supress them.
After the DB connection, put this...
$db-{RaiseError} = 1;
Once you do this you will see that your prepare failed, your SQL syntax is
not valid.
select * from ban where row num 100
It should be rownum, not row num.

display on the page. I wrote the following as part of the script. I get the
error 'Can't coerce array into hash' at the first 'if' into the loop. What am I
doing wrong?
my $sth2 = $dbh-prepare(SELECT id FROM people ORDER BY lname, fname, mname);
$sth2-execute;
my $people = $sth2-fetchall_arrayref;
my $lastperson, $nextperson;
for my $lv (0..$#{$people}) {
if($people-[$lv]-{id} eq $id) {
if(!$lv) {
$lastperson = $people-[$lv-1]-{id};
} else {
$lastperson = -1;
}
if($lv != $#{$people}) {
$nextperson = $people-[$lv+1]-{id};
} else {
$nextperson = -1;
}
}
}

I'm loving Data::Dumper more and more. Apparently, it doesn't return a ref to an array of hashrefs like I figured it would. It it an array of array refs.

Calling subroutines from another file
Hi all. I have a main script file, a package in a separate 'package_name.pm' file and a file 'stuff.pl' that contains functions that both the main script and the package need to use. I've tried adding: require stuff.pl; to both the main script and the package. I can then call functions in 'stuff.pl' from the main script, but when I try from the package, I get: *** Undefined subroutine package_name::function_name called at package_name.pm line 545. So Perl is only looking inside the package for functions, it that right? How do I tell it to look outside the package for functions? -- Daniel Kasak IT Developer NUS Consulting Group Level 5, 77 Pacific Highway North Sydney, NSW, Australia 2060 T: (+61) 2 9922-7676 / F: (+61) 2 9922 7989 email: [EMAIL PROTECTED] website: http://www.nusconsulting.com.au -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/ http://learn.perl.org/first-response

Probably. It's hard to tell without the code.
: How do I tell it to look outside the package for functions?
IMO, the easiest thing to do in the log run is to change
stuff.pl into a module called (perhaps) stuff.pm. The you
can use it. You might end up with something like this:
package stuff;
require Exporter;
@ISA = qw(Exporter);
@EXPORT_OK = qw( foo );
sub foo {
return 'foo';
}
1;
It would be called like this:
#!/usr/bin/perl
use strict;
use warnings;
use lib '.';
use stuff 'foo';
print foo();
__END__
Read the docs for Exporter on how to export functions and
variables easily. Read perlmod for more info on writing modules.
