If you have a question on how to do something in Perl, or you need a Perl solution to an actual real-life problem, or you're unsure why something you've tried just isn't working... then this section is the place to ask. Post a new question!

However, you might consider asking in the chatterbox first (if you're a registered user). The response time tends to be quicker, and if it turns out that the problem/solutions are too much for the cb to handle, the kind monks will be sure to direct you here.

what is a pure perl equivalent for "net user username /domain"?

    Hi; what is a pure perl equivalent for "net user username /domain"? I need to programmatically remove inactive accounts (defined as those no longer employed by the firm) and the mechanism I currently am using, via Perl on Cygwin is to run "net user username /domain" for every username that I have for the two applications for which I am responsible for account management. Is there a Pure Perl module that will return a yes/no answer to the question "is xyz currently an employee?" Thanks, Ken Wolcott
Verilog parse:vhier to get input/output ports

    Hey perl monks! I'm trying to parse a verilog file and would like to get all the module names, input/output port names, whether they're inputs/outputs and the input/output sizes for them. For example:
    module mux_test( din_0 , din_1 , sel , mux_out ); input din_0, din_1, sel ; output [7:0] mux_out; //just as an example //stuff, stuff, and more stuff endmodule
    I'd like to get: inputs = din_0, din_1, sel;
    input size = 1 (for each of them);
    outputs = mux_out;
    output size = 8;
    module name = mux_test.
    I tried using vhier but I could only get module names with: vhier <name> --modules
    Is there any other tool I can use to do this and an example related to mine above would be appreciated.
    Thanks for your help!

    Hi Folks

    I am using www::mechanize module to download a file from website and i could not find how long it's take to complete so i need a progress amount for downloading status, my code is shown below

    $mech->save_content($filename,":content_cb" => \&callback); sub callback { my( $data, $response, $proto ) = @_; $progress_amount+= length($data); my $size = $response->header('Content-Length'); print floor(($progress_amount/$size)*100),"% downloaded\n"; # +print percent downloaded }

    It is not working

    Any Idea...

[SOLVED]:Upgrading Perl 5.8 program to 5.22

on May 23, 2016 at 06:58

    I would like a Perl program I made years ago to run the latest version of Perl 5.22. But the biggest problem I face with this task is the size of the program. The only way I see this happening is if I rebuild the hole framework from scratch under 5.22 while trying to recycle and convert some methods.

    There is no other reason I can see why i need to upgrade other than the fact that the program is stuck at Perl 5.8 and to upgrade to 5.22 would need a major overhaul to the hole framework.

    Are there any advantages of using the latest Perl version that I missed?

    The lesson was... Don't use Exporter in a file you have named "exporter" to keep your variables in scope. But you can use Exporter in a file called "foo" and it will work fine.

    $temp="https://www.ctslink.com/a/document.html?key=2988562"; $mech->get($temp); $mech->save_content();

    The above mentioned url is a pdf file link and url has only key value there is no extension or file name, my question is how do i extract the pdf file name? even i used $mech->title() to get title but it seems a null string only

    Any Idea...

    Hi,

    The output I am getting from SHA256 is different from what I get from other online tools:
    use Digest::SHA qw(sha256_hex); print sha256_hex(5472151337331275); # 32838cef9e4571b4fa9a5297e265cf860a31774de3ca339878d87238af604a45 #result from other online tools: # b5951ee4a7cbfdc9df6b1b74de2d1ba865de40796c756cebe88a806c5a7b9e60

    Am I missing something? Could someone enlighten me?

    Thanks in advance :)

Plack/PSGI Application Deployment

    Hey guys, I am in the process of porting an old CGI based web app to PSGI.

    I am just seeking some clarification about how to best configure my environment for hot deployment / CI.

    Environment (so far)

    • CentOS 6.7
    • Perlbrew
    • PSGI WebApp
    • Starman
    • Server::Starter (??)

    Here is what I want to be able to do:

    1. Have the server start on boot (CentOS Service possibly?)
    2. Deploy code to host (most likely using whiskey_disk or possibly git hooks)
    3. Gracefully restart server

    Where I am really looking for guidance is how to best configure the server/application on the CentOS machine so that it will start on boot and can easily be managed (start/stop/graceful restart).

    Once I have that in place I can automate my deployment fairly easily using various tools.

    I just can't get my head around how to use Server::Starter properly in this instance.

    Thanks in advance! Russ

Are you using Perl 6 in production?

    I've dabbled with it here-and-there (the last real tests I've done were about two years ago). Perl 5 is my favourite language, and I now program in Python professionally.

    I dabbled in p6 prior to learning Python, and there are some obvious similarities, but p6 still has a perl-esque feel.

    It's a slow day here, so I thought I'd ask if anyone here is using p6 in any real-world prod situations, and if so, for what.

    As an aside, I'm curious to know how p6 handles external modules. Yes, I can go do homework, but I thought I'd ask in order to get some feedback here so many people can be apprised. It doesn't appear as though the CPAN handles p6 modules.
