I've played with LWP before, and it worked okay. Another option is to use the lynx web browser to fetch the page source. As far as I know, lynx cannot parse XML, so you'd have to use a separate XML parser after fetching the page with lynx. More options for fetching pages are curl (the module) and curl (the program).

newlines on win32, old mac, and unix
I have to write a simple function which strips out the various
newlines on text files, and replaces them with the standard unix
newline \nafter reading the perlport doc, I'm even more confused
now.
LF eq \012 eq \x0A eq \cJ eq chr(10) eq ASCII 10
CR eq \015 eq \x0D eq \cM eq chr(13) eq ASCII 13
| Unix | DOS | Mac |
---
\n | LF | LF | CR |
\r | CR | CR | LF |
\n * | LF | CRLF | CR |
\r * | CR | CR | LF |
---
* text-mode STDIO
In text-mode, I open the file, and do the following:
while (defined(my $line = INFILE))
{
my $outline;
if ($line =~ m/\cM\cJ/)
{
print dos\n;
($outline = $line) =~ s/\cM\cJ/\cJ/; #win32
} elsif ($line =~ m/\cM(?!\cJ)/) {
print mac\n;
($outline = $line) =~ s/\cM/\cJ/g; #mac
} else {
print other\n;
$outline = $line; #default
}
print OUTFILE $outline;
}
It works fine on unix when I run the unit tests on old mac files, win,
and unix files and do a hexdump -C on themhowever, when I run it
on win32 perl 5.6.1, it is not doing any replacement. Teh lines remain
unchanged.
My understanding is that \n is a reference (depending on which OS your
perl is running on) to CR (mac), CRLF (dos), and LF (unix) in
text-mode STDIO. So replacing CR (not followed by LF) with LF should
work on mac, and CRLF with LF on dos, and leaving LF untouched on *nix
(other)then it shouldn't be a problem...however it appears that
\cJ is actually different on win32 than it is on unix.
so is \cJ is actually \cM\cJ on win32?

On 6/8/06, Graeme McLaren [EMAIL PROTECTED] wrote: Hi all, this class that I have written lists the contents of a log table when the $log-view method is invoked. There is some hardcoded SQL in this method and all I do is pass it a number which then looks up the relevant records. This really isn't a reusable class as far as I understand it because it assumes that anyone else using it would have a log table with various fields of a certain name defined. How can I make this completely reuseable, should it be documented saying that you need to create a log table with various fields before using it or should I code it so that the table name and fields have to be passed in and the script would then take care of it? Your thoughts and comments are as always - appreciated. Cheers, G :) Interesting. Reusable by who? Is it part of a package you're going to distribute? is there an included mypkg.sql file they have to run? Typically, package installs come with a config file where a user can specify tablename_prefix. so it would be pretty seamless if all they had to do was edit mypkg.conf and change: table_prefix = mypkg_ so then log_table would become mypkg_log_table, while columns would remain the same. You could have your module simply read the config file inside the implementation of $log-view(); The table structure(s) should stay the same, but give them a chance to override the table names incase they collide with pre-existing tables. I've found this to be the best way to ensure not dropping tables on accident, especially if you load an sql file with drop table foo if foo exists. I almost did that at work the other day on a table with 1 character diff in the name (i was lucky, and added dp_ to all my table namespaces). -- Anthony Ettinger Signature: http://chovy.dyndns.org/hcard.html -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/ http://learn.perl.org/first-response

Hi all, I've just been reading a bit about accessor get/set methods. I
have a method:
sub even{
my $self = shift;
my $even = shift;
$self-{_even} = $even if defined($even);
return $self-{_even};
}
This basically does what a get and set method would do. So why would I
need a set/get methods? This value is passed to the object like so:
It's a question of style, largely. Some people prefer their code to be
very clear about whether your getting or setting. Using explicit set and get
methods can also help prevent bugs; you won't accidentally make a read-only
value writeable, because you will avoid writing a set_ro_value method -- if you
only have a get-and-set ro_value method, you might forget to special-case it to
be get-only.
Also, you'd probably avoid bugs like the one you introduced above. What
happens if I want to clear the even value?
$obj-even(undef);
This does not affect the value; I can't undef even.
You probably wanted:
sub even {
my $self = shift;
return $self-{even} unless @_;
return $self-{even} = shift @_;
}

modifying @INC permanently
Is there a way to modify @INC for the perl installation as a whole? All my scripts have logic to push the same directory to @INC. It's rather repetative. I know I can export PERL_LIB environment variable, but I need something for all system users (including win32). -- Anthony Ettinger Signature: http://chovy.dyndns.org/hcard.html -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/ http://learn.perl.org/first-response
Re: modifying @INC permanently
You do not need logic to do that. It would seem better to use: use lib '/path/to/my/misplaced/perl-modules'; The point is to not have to specify a local path at all: use lib qw(/path); push(@inc, '/path'); Each script tests for OS: linux/sunos, and win32, and pushes the path to @INC accordingly, based on path names. I tried File::Spec, but use lib won't take a variable as it's evaluated before runtime, so that left me with push. -- Anthony Ettinger Signature: http://chovy.dyndns.org/hcard.html -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/ http://learn.perl.org/first-response

definitely the better way to handle it, although you don't need
the || unless you want a default value. Setting it as empty is still a
value, so you potentially could have empty values in your database. if
(defined($name)) would be better, but can be rather cumbersome.

This might be a little more clear if you break down the way arguments

you're aware that the arguments are passed in as a list name @_, it
looks like the arguments are something like this:
@_ = ( # A list
{ _name = 'something' }, # a hash reference (objects are
hashes in perl)
'some set name string' # a string
);
The first version extracts the arguments so that you can refer to
them by names that might have some meaning to someone maintaining
your code latter on. The second version accesses them directly.
sub name{ #version 1
my $self=shift;
shift is going to give you $_[0]
my $set_name=shift;
This sets $set_name to $_[1]
$self-{_name}=$set_name if defined $set_name;
So this is equivalent to
$_[0]-{_name} = $_[1] if defined $_[1]
the '-' is to dereference the hash reference stored in $_[0].
return $self-{_name}
}
Another version for the subroutine name
sub name{ #verstion 2
$_[0]-{_name}=$_[1] if defined }$_[1];
{$_[0]-{_name}
}
I feel a little bit confuse about the verion 2
subroutine name. The way it gets the value of
attribute name looks like this to me:
array element-{_name}
(I know that the $_[0] in the default array @_ is
actually an object $self. )
Hope this helps

I could also write one monster program that combines all six programs. That

Perhaps I could have a switch statement to only require those modules

if it's a standalone script you want to run, use system() or `` if you
need to capture output.
if it's just a bunch of routines you want to execute, you could put
the main routine in the script into a sub called from within your
wrapper script, including the library script with
require('/path/to/script.pl'); at the top. (no need for shebang line
here).
require('/path/to/foo.pl');
foo(); # call main::foo sub routine defined inside foo.pl

i wrote a program some months back which utilised a compelx regex sub

don't know how to give the regex the full line of text, and assign the
extracted value into a variable for use later on.
i'd really like to get my head round this. if anyone's got any good guides,

What do you mean by import? Variables aren't imported from BEGIN
blocks. They're declared in BEGIN blocks, and a variable declared in a
BEGIN block should be no differnt than a variable declared at the top
of your script. Except, of course, that you guarantee compile-time
execution and you can put the block anywhere. But none of that effects
the way the variable declaration functions. If you're having trouble,
get rid of the BEGIN and END blocks and just declare your variables
right after 'use strict' and 'use warnings'. You can go back and put
them in the BEGIN block later.
Anyway, none of us can really help you unless you send real code.
If I do *not* import with our $foo; inside main::something(); I get
the following errors:
The you've done something wrong somewhere else.

Again, what do you mean by import? You're sample pseudo-script does
not exhibit the beavior you describe, nor does it import any variables
. Are you actually importing the variable from somewhere else? Another
file perhaps? Are there other packages in your file you haven't shown
us? What errors, if any, does the following script produce in your
Perl? Perhaps your installation is buggy. This should print 'foo' and
exit:
#!/usr/bin/perl
BEGIN {
use strict;
use warnings;
our $foo = 'foo';
our $baz = 'baz';
}
sub bar {print $foo;}

Yes, I did look, it wasn't too descriptive.
What I ended up doing was reverting back to the deprecated method of
use vars qw($foo); at the top of the library.
using our within the sub routine to import globals seemed to work,
but one of my machines is v5.6 so that won't work.

Correct, I should've provider a better example of what I'm trying to do.
I need to require(logger.pl); at the top of a bunch of scripts (ie -
tool.pl), and I want to log start/end times without touching
tool.pl. So I accomplish this with BEGIN/END blocks from within
logger.pl, which set the start time when the tool.pl is executed, and
then calls log_time(); from the END block when the tool.pl is
finished.
The tools are such that there is no use strict; or -w in use (and
I'd rather avoid touching these beasts if I can help it at all).
Here's a clearer example of logger.pl that I will be including in my tools:
#!/usr/bin/perl -w
use vars qw($start_time $end_time);
use strict;
BEGIN {
$start_time = time();
}
sub log_time {
my $exit_code = shift;
my $elapsed_time = $end_time - $start_time;
print $elapsed_time, \n;
}
END {
$end_time = time();
log_time($?);
}
__END__
I had originally posed the question using our inside log_time(); to
import the globals defined in BEGIN/END blocks (which works by the
way); however I have since discovered that one of my systems is using
a version of Perl 5.6, inwhich our is not supported, so the above
method, although deprecated, works across the board for my
environment. (I'm not the admin, and getting Perl upgraded is not a
viable option at this time).
The only change I have to make to each tool-N.pl is:
require(logger.pl); at the top.

ok, I can ditch the BEGIN block altogether and use $^T - time(); in the END

I would have to move the call to log_time(); to the END block, since it

Perl Hash Question.
Hi there everybody, I have a question and I am pretty stumped for the answer.
I have a program that does the following:
A = Reads URI from URIHASH.
Visits site A.
Parses all URIS on site A and for each URI found adds the URI to the URIHASH.
A = Reads next URI from URIHASH.
Visits site A.
And so on... until the MAX URIHASH size is reached.
My question is, is there any way to iterate through a hash in this manner.
I tried foreach():
foreach $key (keys %URIHASH){}
and this does not work. What occurs is the entry that exists in the
URIHASH when the foreach loop is entered, is processed.
any additional entries that are added during the loop are not processed.
I also tried each():
while (($key, $entry) = each %URIHASH){}
When additional entries are added during the loop, this seems to
produce unexpected behaviour. In my case an infinite loop.
I should also mention that the URIHASH is tied to a file on the disk.
Any help at all would be appreciated.
Thank you very much.

that data.

$data{ext2} = 9;
$data{ext3} = 10;
# Dummy Test Formula
$formula{Addition} = ext1 + ext2;
$formula{Subtraction} = ext3 - ext2;
$formula{Brackets} = (ext2 + ext3) - ext1;
# I can quite easily print these out and I could put the $data{extX}

Merging Hashes
Hi,
I'm new to hashes, and I've been playing around with the
following for a while... I'm just not getting it.
I have two hashes, one containing data read in from a file,
one with current data. I'd like to merge the two, adding
any new keys and values into the hash, and for any keys that
exist in both, I'd like the append the values onto the values
for the same key in the original hash.
An example...
Hash 1 (from a file)
host1=760,760,759
host2=765,760,760
host5=130,200
Hash 2 (Current)
host1=758
host2=760
host4=450
host5=210
I'd like the merged hash to be:
host1=760,760,759,758
host2=765,760,760,760
host5=130,200,210
host5=450
I'm using an example out of the perl cookbook, and trying to
modify it to do what I want, but it isn't working out...
The three hashes are:
%host_list (Hash 1 in the example)
%current_list (Hash 2 in the example)
%final_list (The result of the merge)
Here's the code I have so far for the merge (this is borrowed
heavily from the Perl Cookbook):
foreach $item ( \%host_list, \%current_list) {
while (($key, $value) = each %$item) {
if (exists $final_list{$key}) {
$value .= ,$current_list{$key};
}
$final_list{$key} = $value;
}
}
Can someone point me in the right direction?
- Tony

}
But now I am having problems counting if there is one record of that line?

I'm attempting to use the following code on an AIX machine to
monitor the error log (using the errpt command).
I'm sure parts of it are very ugly, but it's (mostly) working.
The part that isn't is the foreach loop. What it's supposed to
do is as follows:

RE: Microsoft Services for UNIX/LINUX
Glad you've found a solution. Just thought I'd drop a note about some of the things I've had success with. We have a few scripts (originally written as shell scripts in csh) that I've converted to perl. They reside on a box running AIX 5.1. On a win2k box I've installed the Windows services for unix 3.0 NFS gateway, which allows client machines to map to windows shares, which are just gateways to NFS exports on the AIX host. The windows clients have activestate perl installed, and are configured to map the NFS share on log in. The end result is that the users can double click on the perl apps without needing to know they're even touching a *nix box. - Tony -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Tuesday, January 06, 2004 11:17 AM To: Kevin Old Cc: [EMAIL PROTECTED] Subject: Re: Microsoft Services for UNIX/LINUX Hello, Putty has this: Plink (a command-line interface to the PuTTY back ends) http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html Thanks to all again.

'print' output on one line
I have a perl program ( with DBI ) which prints out a line to STDOUT
after every 100 database commits. I would like the 'print' to just
refresh the current line every time but - not knowing how to get around
it - the program instead prints a new line every 100 commits like so:
INFO 3: start deleting rows.
Rows deleted: 100
Rows deleted: 200
Rows deleted: 300
Rows deleted: 400
.
.
.
INFO 4: delete_rows.pl program ended.
I would like the output to just stay on one line and just update the
count as the program proceeds. So the output - when done - would just
be
INFO 3: start deleting rows.
Rows deleted: 400
INFO 4: delete_rows.pl program ended.
Is there a 'print' option/escape character the sends the file pointer (
for STDOUT in this case ) back to the beginning of the line?
Here is the current code segment - the focus here is on the last 'print'
statement:
print INFO 3: start deleting rows.\n;
while(($row_data) = $sth1-fetchrow) {
if(! defined ($sth2-execute($row_data))) { # execute DELETE
print ERROR 4: execute of DELETE statement failed.\n;
exit(int 4);
}
$row_counter = $row_counter + 1;
if($row_counter = 100) {
$dbh-commit;
$rows_deleted = $rows_deleted + $row_counter;
print Rows deleted: $rows_deleted\n;

RE: 'print' output on one line (thread closed)
Alright, gents, you and I were both right...\r works, as it should. It turns out that these computers today - and Perl - are even faster than I thought. My test data set was only 300 rows so by the time the program ran - and deleted - 300 rows the Perl program had only enough time to print the output once, making it 'appear' to not work. I had a suspicion that that may be the problem so I increased my test data set to 6000 and it worked fine. Thanks all!

RE: Timing several processes
AIX 5.1, actually. Though eventually linux, windows,
and possibly other OS's will be in the mix.
I'm writing this with the idea of it being very modular
in that each server will do it's own check ever 15
minutes or so, and that the webserver will only connect
and grab that data when someone goes to the page (using
a cgi to parse it up and display it in a heirarchical
fashion). The server will access the data via NFS (the
NFS exports are already in place due to another project)
Writing to a file gives me a history of data should any
individual box go down. (Especially the webserver in
this case, since it is periodically taken offline during
the course of any given week due to its role in the
overall project these machines run)
I also plan on the actual programs that are called to be
set up in a config file. Something along the lines of:
APP1_HANDLE = sar
APP1_EXEC = sar 5 5
APP1_LOG = /log/monitor/delta/sar.out
APP1_PARSE = /log/monitor/parse_sar.pl
APP1_SUMMARY = /log/monitor/delta/sar.summary
I'm planning on figuring out how to put all of those into
a hash, and then using a foreach loop to exec each one, and
another foreach loop to wait for each to complete, and a
final foreach loop that runs the parse for each one and
generates a summary. The summary files will all be in a
standard format that the webserver will use to genrate
its display.
I had not thought of stderr from the commands, so
you're right that catching it is something I need to
think on.
The other bit I'm working on is to make an options
file for each server (generated before the summaries
are parsed) that contains info like number of processors,
and tuning options (set with schedtune and vmtune, etc)
that can be used by the APP_PARSE scripts in calculating
results. (Thrashing detection, etc).
I know, it's all a little complex, but the individual
pieces are fairly simple in design. And in the end it
will meet the goal that management put forth, which is
what keeps me paid :)

and you will notice that the sar command will
take about 25 seconds and the vmstat about 20.
but then there is that minor nit about
exec vmstat 5 5 /log/monitor/delta/vmstat.out
or die cannot exec vmstat: $!;
since in theory exec WILL not return, so if it failed
why not keep it in the proper context...
Then there is that Minor Nit about not controlling 'stderr' which can
lead to things like:
vladimir: 60:] ./st*.plx
Running vmstat
Running sar
sh: /log/monitor/delta/vmstat.out: cannot create
sh: /log/monitor/delta/sar.out: cannot create
Waiting...
done!
vladimir: 61:]
So while you are in the process of learning
fork() and exec() why not think a bit more
agressively and go with say a pipe to pass
back the information so as not to buy
the IO overhead of writing to files?
While the following was written for a command
line 'let us get interactive' type of solution,
it might be a framework you could rip off
and use:

Timing several processes
Hi all! I'm wanting to write a simple web-based tool to see the status of several servers at a glance. I know there are many solutions existing, but I can't learn as much about perl by just using one of those as I can by writing my own. The first step I want to do is call a script from cron that runs several basic monitoring tools (sar, vmstat, df, iostat, etc) and saves the output of each to a file. Then I'd parse those files up, and write a summary file. Easy enough. And I could certainly do it with by calling the tools one at a time. However, I'd like to get roughly 1 minute of vmstat, iostat, and sar output Simultaneously. So I'm supposing I'd want to fork off each process, and then when those are all done come back and run a script that then parses those results out for the individual statistics I'm looking for. I've never used fork before, and while it looks fairly straight forward what I am not sure of is how to make sure all of those forked processes have completed before moving on and parsing the files. Any pointers? Thanks in advance -Tony -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
