Bowing to the inevitable - Perl Hacks
Data Munging with Perl was published in February 2001. That was over 23 years ago. It's even 10 years since Manning took the book out of print and the rights to the content reverted to me.Dave Cross (Perl Hacks)
Its been a long time since i've had to hack some code together so here just asking for advice as to where to start.
I have a group of printers (all have same web interface) on the corporate network. I would like to make a simple script that can login, and upload a config file (really its a list of users that have can scan documents, it doesn't matter what).
I've tried to google this with limited results, so wanted to reach out here to see if PERL would be the best answer for this.
I guess my question is, what modules should I look at to connect to a webpage in order to login then access a page behind the login and upload a file?
I looked into Mechanize but I do not believe it can handle javascript. Any advice or test scripts that do something similar would be greatly appreciated.

I’m currently having to modify a library that used Smart::Match extensively since I can no longer turn off the zillions of lines of experimental warnings in recent Perls. For people who are in a similar situation it’s looking like Data::Compare can replace the situations where I was doing ‘@foo ~~ @bar’, and it’s easy enough to write a “does this hash have this key” helper.
Meta complaint: I was already a bit annoyed at the whole smartmatch “oh whoops actually this is now experimental” saga but now that I’m stuck fixing this breakage I’m $annoyed++. Im getting annoyed enough that I may choose an older Perl that was “good enough” and just stop using the new ones

Hello all I have a .pl CGI program that calls a module with lots of code I'll call it LotsOfCode.pm now I need to update a few subs in it and possibly add a dependency.
The pl file looks like this:
use LotsOfCode;
Lotsofcode->cat();
LotsOfCode->dog();
Lotsofcode->fish();
Now I'd like this to say the same but I need to improve fish and cat. Say LotsOfCode.pm looks like this:
package LotsOfCode
sub fish {}
sub dog {}
sub cat {}
1;
I'd like to
mkdir ./LotsOfiCode
nano LotsOfCode/fish.pm move sub fish{} here
nano LotsOfCode/dog.pm move sub dog {} here
nano LotsOfCode/cat.pm move sub cat {} here
what do I put in the top of these new files in \LotsOfiCode ?
package LotsOfCode::fish;
or
package fish; ?
or
nothing is what I have so far just
sub fish {}
then in LotsOfCode.pm
do I go:
package LotsOfCode
use LotsOfiCode::fish
use LotsOfiCode::dog
use LotsOfiCode::cat
1;
or
do LotsOfCode::fish;
do LotsOfCode::cat;
do LotsOfCode::dog;
Thank you all in advance I get the more than one way to do it idea of Perl but feel like I keep fumbling with mixing old and new code.

This might be Perl/docker-perl#161 but if I filed this in the wrong place, let me know. Keeping these things current is the sort of thing I'd pay for.
Pulling perl images locally give the same warnings for old perl versions, although my local docker will still run them:

I have an input string that has "comments" in it that are in the form of: everything after a ;
is considered a comment. I want to remove all comments from the string and get the raw text out. This is a pretty simple regexp replace except for the fact that ;
characters are valid non-comments inside of double quoted strings.
How can I improve the remove_comments()
function to handle quoted strings with semi-colons in them correctly?
```perl use v5.36;
my $str = 'Raw data ; This is a full-line comment More data ; comment after it Some data "and a quoted string; this is NOT a comment"';
my $clean = remove_comments($str);
print "Before:\n$str\n\nAfter:\n$clean\n";
sub remove_comments { my $in = shift();
$in =~ s/;.*//g; # Remove everything after the ; to EOL return $in;
} ```

Hi,
im looking to put my website written in perl that currently runs locally inside apache out on the internet.
I dont want to host myself, and i dont have lots of spare time to config or money to spend for a vps.
Does anyone have experiences and can recommend a webhoster for maybe 10-15 bucks a month where i can just get a simple interface with ssh, where i can put an index.cgi somewhere(dont care if its in cgi-bin or public_html or something else,
i want something where i can just checkout my git repo thta contains index.cgi in its root and just works.
Thank you in advance!

I know it is something of an obscure corner of everything that Perl can do, but Perl is excellent for "one-liners".
Has anyone developed a module of convenience functions for use with one-liners? I have something in progress but I'd like to see if there is established prior art.

Stack:
Nginx FCGI CGI::Fast HTML::Template::Compiled Redis CentOS Linux 7.9 spawn-fcgi
I have a Perl application that runs on the above stack.
On process init it does a lot of loading of big hashes and other data into global variables that are mostly preloaded and cached in a distributed Redis install.
To start the application spawn-fcgi creates 6-8 processes on a port nginx then connects to trhough their fcgi module.
The challenge:
— The init process is computing and time consuming; and doing that concurrently six times peaks CPU and overall leads to a ~20-25 second delay before the next web request can be served. And the initial request to each of the six processes has that delay.
I tried loading the content in question directly from Redis on demand but the performance keeping it in memory is naturally much better (minus the initial delay).
is there an architectural pattern that I am not considering here? I am thinking of things as eg. only spinning up one process, having it initialize and then clone(?) it a few times for serving more requests.
I could also think of a way where only 1 process is spawned at a time and once it completes initiation the next one starts; would need to verify that spawn-fcgi can support this.
So my question to this community is if I am missing an obvious better solution than what is in place right now / what I am considering.
Thanks in advance.

I am moving a pile of stuff off of an older Intel Mac Mini onto an M2. Have almost everything migrated, but am stuck on getting a Perl script that relies heavily on DBD::mysql to work. I finally got cpan to build the module, but when I try to use it in actual code, I get: dyld[82852]: missing symbol called. I go through this mess periodically with OS upgrades...and it's possible that this is (once again) OSX ignoring the module because it's not signed. But the given error sounds more like Perl not finding the dynamic library(s) the module was built with...if I just have a script containing "use DBD::mysql;", that doesn't throw an error, which suggests Perl found the module and loaded it. But chokes when it tries to use it.
I'd be fine with building this module with static libraries, if the process of doing so is easy. But have not seen an easy option to cpan to go that route. Suggestions?

This is the frame body I was using:
our $frame_body = $mw->Frame(-background => $color_theme_bg, -foreground => $color_theme_fg)->pack(-side => 'top');
And I have many widgets like labels, dropdowns, buttons, etc... within that frame like below:
$frame_body ->Label( -text => "@_", -font => $arial_font, -foreground => $color_theme_fg, -background => $color_theme_bg, -highlightthickness => 0, -takefocus => 0, -relief => "flat", -justify => 'center', )-> grid( -column => $mw_col_ctr, -row => $mw_row_ctr, -sticky => "nsew", );
May someone help me the best way to apply a "vertical scroll bar" on the right side of this frame?
Its also nice if automatically adjust incase I manually resize the window. 😀

Is it possible to display an image to the user, without loading all the trappings of a whole widget / event-loop environment like Prima, Tk, Wx, Win32::GUI, etc?
Specifically, I want something simple that I can execute in a BEGIN block to display a splash image to the user while the rest of the application is compiled and initializes, which takes about 5-10 seconds. The program in question is a perl Wx application running under MS Windows.

Vim highlights subs with a signature params as red/orange to alert you it's incorrect. Now that Perl actually supports signatures and this is no longer a syntax error I need to find a way to disable this. This is really a Vim question, but I'm sure some other Perl nerd out there has run into this before me.
Has anyone figured out how to disable this "warning" in Vim?

Hi, I recently got an offer for Senior SWE (current title at my company now) for a company that heavily utilizes Perl. I was wondering if folks from this community could offer some insight on what it's like working with Perl and also what, if any, potential long-term career implications are of becoming a Perl developer? Particularly I'm worried of pigeon-holing myself since Perl is not as heavily used in todays age and this company does not make use of modern cloud tools and deployments.
I am a Java developer (5 YOE) at a enterprise software company that is deployed in GCP. We are pretty regularly adopting new technologies so I'm gaining some valuable and relevant industry experience here but I am looking for a change and more opportunity to lead projects and mentor junior engineers.
The company seems good, great WLB, I liked the manager, and with the bonus (base is roughly the same) it would be about a ~8% TC increase plus a lot more stock (monopoly money, private RSUs).
Does anyone have experience transitioning from a Perl based company to a cloud based company with a more modern tech stack? Is this a backwards direction for me, should I continue with my Java development and instead look for opportunities that will offer more marketable skills?
Any input is appreciated, thank you for reading.
