I'll start by saying I am new to Perl.

Short Story: How can I rename the namespace of a Perl package? Either doing this on an already installed package OR do this on a new package before I compile it?

Long Story (if you are interested):

I have an existing Perl script that runs a package imported from a vendor named Infoblox that we use to automate changes to records on a server. The Perl packages are custom to Infoblox AND the version of their OS that happens to be on that server. We'll call this package version 7.

I need a way to, without disturbing existing functionality, run scripts from the same Linux machine that interact with a different Infoblox server that runs a newer version of the Infoblox operating system. Since they have released a newer version of their OS (version 8) they also have a newer version of their Perl package. After testing I am unable to make API calls to the version 7 server using the version 8 perl package. Likewise I am not able to make API calls to the version 8 server using the version 7 perl package. I tried installing them at the same time but since they use the same namespace of "Infoblox" that did not work out at all.

I have no experience creating perl packages but it seems that I should be able to alter something in the new package before I compile and install it which would give it a unique namespace. Any tips on where that would be? ALternatively I thought I could use CPAN or package or some kind to rename the existing (version 7) already installed package to something unique which would mean installing version 8 package would work okay. I found Package::Rename on metacpan.org but have been unable to figure out how to make it work.

Any help would be appreciated.

Hi Monks,
I have list of labels embedded in textarea.
After deleting/removing label from textarea, I want to update the value of remaining labels in textarea all the time.
Any help on this would be appreciated.

Thanks

Hi - the relevant lines of my script are

-------
use LWP::Simple;
$pass=1;
my $doc = get('http://forecast.weather.gov/MapClick.php?CityName=Sudbu
+ry&state=MA&site=BOX&lat=42.3667&lon=-71.4') || die {$pass=0};

This is part of a script that runs every 15 minutes that gets this webpage, parses some specific info from it (like temperature), and writes the info to a file so my home control program can later open the file and act on the data. My problem is that a few times a day, the get never returns, and the script hangs. I have another script running that detects the hang, and kills and restarts the script. But that's clunky. I'd like to either eliminate the hang, or detect the hang -within- the script. But that is a level of Perl that I haven't dealt with before so I'm wondering if anyone can point me to a recipe. Thanks!

Further background - using ActivePerl on a W7 machine this code never hung. Switched to W10 and ActivePerl stopped supporting the get properly so I switched to Strawberry Perl (which i like better overall) but where I am having this intermittent issue. (this is probably the "fanciest" thing I do with Perl on my PC so for everything else either Perl works fine).

Many Thanks!

I have some tab delimited data:

name1 \t data \t moredata \t evenmoredata \t
name2 \t data \t moredata \t evenmoredata \t
etc.

And a list of names which are interesting;

name1 name2 name3 name4

I have been using awk to extract rows from the tab delimited file where column 0 matches my name, and looping through my list of names in order to extract all matching rows. But as my data grows, this task gets very time consuming (6 hours for 200 mb worth of data; and I want to analyse files that are 10 gb!)

So I would like to user perl (I have no perl experience, previously worked in bash).

My plan:

Convert each entry in the data file to a key (the name column) and corresponding hashes (all the other data in each column).
Do a regex match between my list of names, and my hash keys.
Use the matching hashes to extract the keys.

But I have no idea where to start.

Any advice?

My goal is to develop an automated means to obtain the number of followers for each of a list of WordPress blog feeds (eg https://wordpress.com/read/feeds/93815501), which display the number of followers in a way that is captured by a copy-and-paste but is not in the HTML page source code. In order for these pages to display properly I need to be logged into a WordPress account and have JavaScript enabled in the browser.

So far I have the following code:

use strict;
use warnings;
use LWP::UserAgent;
use LWP::Simple;
use HTML::TreeBuilder;
print HTML::TreeBuilder->new_from_url('https://wordpress.com/read/feed
+s/94271045')->as_text;
[download]

This code produces the following output:

> WordPress.comPlease enable JavaScript in your browser to enjoy WordPress.com.

Naively it seems to me that since my browser can interpret a web page using JavaScript without any a priori information, Perl should be able to as well. Is this possible? If not, why not?

I'm a Perl novice who wants to get code running without learning Perl "from the ground up". My strategy has been to find working code samples that do pieces of what I want, then change them incrementally until they do all I want. I'm using Strawberry Perl on Windows.

Can you offer guidance or link to somewhere that explains it for novices like me? Thank you.

use strict;
use warnings;
use CGI::Carp qw(fatalsToBrowser);
use File::Copy;
use File::Path qw(remove_tree rmtree);
use File::Fetch;
$File::Fetch::WARN = 0;
use Fcntl;
use URI::Escape;

use English;

my $ff = 0;
eval { $ff = File::Fetch->new(uri => $PARAMS{url}); };

if (not $ff) {
  if ($DEBUG_OP_ADD_COVER_PHOTO) {
    $output .= "failed to retrieve image: " . $ff->error . "<br>\n";
  } else {
    print error_redir(redirrer($OP_QUERY, $OP_FILE_MANAGER, $FOLDER_QU
+ERY, $FOLDER), "Failed to Retrieve Image: " . $ff->error);
    exit 1;
  }
}

the fetching process emits a completely different error message, and it's printed (i presume to STDOUT) before i get to print anything to STDOUT! which causes "internal server error", and i can't get the thing to stop printing that damn junk out, it 'breaks' things!

Edit: Added "use" statements which may affect your answer. the code in this post is only a very small part of a much larger program.

Hi Monks,

what is difference between below two filenames/strings, as first one doesn't seems needed any utf-8 encoding and second one needed.

How can I check the difference between below two filename/strings or what condition will differentiate these two files.

1. test1℗ὓ.txt #this works without further encoding
2. 1669-SCC-HôpitauxdeSaint-Maurice-POC.PIF #but this needs utf-8 encoding.

Thanks.
