I am fairly new to Perl. I did a lot with it in the mid 90s and came back about 8 months ago. There is a lot I dont know and probably a lot of things I have forgotten.

I picked up Perl to write a couple of applications that I was hoping could run on MacOS, Linux,OpenBSD, and Windows. Perl runs on all of them and many come with Perl built in. Simple scripts I have written run pretty well. (Lets forget about Windows for now).

When I start using libraries(packages?) there is a world of hurt.

Now some libraries pretty much usually work, but many do not. Which works and which do not seems to be dependent upon the operating system and distro.

Then I have to start with what version of Perl is running everywhere. That is annoying.

I end up spending a lot of time on a new machine when I want to run my application, doing nothing else than trying to get the libraries installed.

So I decided to adopt PerlBrew (havent tried it on OpenBSD yet) That should give me a stable version across the differnt platforms.

Then I decided I wanted to write a shell script that would handle installing all of the libarires I might use once and for all so I would know they were all accounted for.

perlbrew exec -q --with perl-5.40.0 cpanm install DBI

Then libraries I have pulled from CPAN do not work.

Google here and Google there.

Ok install GCC and make (I should have known this) More problems:

I found a few of these: "Why are you using CPAN for this? Use the compiled packages that come with <OS><type>"

Hmm I would have thought that CPAN shold be the best source? How do I know what exists as pre built packages on what platform?

Using apt search "perl" or "-perl" or "perl" does not help that much.

I have XML::LibXML working on Mac but getting it working on Ubuntu 22 I have been able to do. I have even tried to start OpenBSD yet)

Is writing cross platform applications in Perl meant to be this difficult?

Should I avoid libraries at all costs and write an aweful lot of code myself?

Is there an easy way to guess what libraries will almost certainly work and what libraries will most likely never work? Some kind of warning system?

Should I look into using pp? I havent yet figured out how to make it compile for Ubuntu,MacOs,OpenBSD yet.

In GoLang its a couple of flags to set for each architecture and off it goes.

ShouldI look into Par files? (or was it Far) that are supposesd to contain the nessescary libraries within itself?

What am I doing wrong?

Libraries in my current set Given all the experimenting some of them are now wrong.

Array::Set, Array::Unique, Bundle::LWP, Data::Dump, Data::Dumper, DateTime, DBD::SQLite, DBI, Digest::file, Digest::MD5, Digest::MD5::File, File::Basename, File::Compare, File::Copy, File::Find, File::Find::Rule, File::Glob, File::Path, File::Slurp, File::Spec, Image::ExifTool, Image::Info, IO::All, List::Compare, List::Gen, List::MoreUtils, List::SomeUtils, List::Util, List::UtilsBy, Log::Minimal, LWP, LWP::Simple, Path::Tiny, Term::ANSIColor, Text::Fuzzy, Type::Tiny,Moose,MooseX::Types,WWW::Mechanize

You may have noticed the slow pace of Corinna development. As it turns out, there's an easy way to speed up the development: tell Paul.

I had a call with Paul "LeoNerd" Evans last night and this, including his email address, is being shared with his permission.

As you might imagine, being a core Perl developer, Paul has many things on his plate. Currently has has tons of PRs against the Perl core, he's doing new work such as experimenting with data checks (don't call them "types"!), and is active on the Perl steering council and in P5P. However, he's previously mentioned that he doesn't get much feedback on his work. For adding something as important as Corinna, just blindly adding it without hearing from the community is bad. Yes, we had a multi-year design phase and Corinna is much better for it, but that doesn't mean it's perfect and we don't want to screw this up.

So here's where you come in. Email Paul at leonerd at leonerd.org.uk. Tell him your thoughts about Corinna. He's he one implementing it and working in isolation as he is, despite his work with Object::Pad, isn't good. Tell him what you like, what you don't like, what you'd like to see next, what bugs you've encountered, and so on. Without hearing from you, he has no way of judging community thoughts/support for this project, so he needs your help.

If you'd like a quick refresher on the new syntax, I've written a short introduction. Here's a dead-simple LRU cache written in the new syntax:

use feature 'class'; class Cache::LRU { use Hash::Ordered; field $cache = Hash::Ordered->new; field $max_size :param :reader = 20; method set( $key, $value ) { $cache->unshift( $key, $value ); # new values in front if ( $cache->keys > $max_size ) { $cache->pop; } } method get($key) { return unless $cache->exists($key); my $value = $cache->get($key); $cache->unshift( $key, $value ); # put it at the front return $value; } }

• Add tests for error parameters.
• Rewrite the tests so that the functional tests are first and then the errors.

Hi! Asking for a wisdom here...

We have a module that modifies signal handler $SIG{__DIE__} to log information and to die afterwards. Hundreds of scripts relied on this module which worked fine in perl 5.10.1.

Recently we had the opportunity to install several Perl versions but unfortunately a large number of scripts that used to work with Perl 5.10.1 now behave differently:

• Failed in 5.14.4: /home/dev/perl-5.14.4/bin/perl -wc test.pl RECEIVED SIGNAL - S_IFFIFO is not a valid Fcntl macro at /home/dev/perl-5.14.4/lib/5.14.4/File/stat.pm line 41
• Worked without changes in 5.26.3: /home/dev/perl-5.26.3/bin/perl -wc test.pl test.pl syntax OK
• Worked without changes in 5.38.2: /home/dev/perl-5.38.2/bin/perl -wc test.pl test.pl syntax OK

Many of the scripts can only be updated to 5.14.4 due to the huge jumps between 5.10 and 3.58; But we are stuck on that failures.

Was there an internal Perl change in 5.14 which cause the failures but works on other recent versions without any update on the scripts?

Cheerio!

My environment is perl/5.18.2 on CentOs 7

I'm trying to use a SWIG generated module in perl, which has a c plus plus backend. The backend.cpp sets an environment variable, $MY_ENV_VAR =1

But when I try to access this in perl, using $ENV{MY_ENV_VAR} this is undef.

However doing something like print echo $MY_ENV_VAR works

So the variable is set in the process, but it's not reflected automatically since nothing updates the $ENV data structure.

I'm assuming it may work using some getEnv like mechanism, but is there a way to reset/ refresh the $ENV that it rebuilds itself from the current environment?

Im working on a script to test using a jump server to reach remote devices.

I'm able to connect to the jump server using Net::SSH::Expect, however, I'm not sure how to then ssh to a remote device (network element).

Is there a way to create that ssh to the remote device inside the jump server's connection?

First things first, I am a data engineer but have little experience in Perl. I've been able to make some easy updates to scripts in the past but this one is a bit tougher.

I have been asked to update a Perl cgi web app that someone wrote ages ago that is used to view and manipulate text files. Currently it is hosted on server (X) and manipulates the files on that same server. However, we have to have backups/mirrors of the data on a dev server and another prod sever (Y). I.e., if I push the button to move the file to a different folder, it should do that on all three servers instead of just X. I added code to do this, referencing the additional servers with their UNC names, but I just get an error "No such file or directory" (which is not true). Googling has suggested that there may be an issue with permissions, but I can bring up the Y and DEV servers from a windows file explorer using the same path so I don't think that is necessarily the issue.

Example: Here we are trying to copy the file with a letter appended a given number of times. It works fine on the X server, its when trying to make it also work on the Y and DEV servers I get an error.

our $DIR_X = "\\\\serverX\\folder\\subfolder" ; our $DIR_Y = "\\\\serverY\\folder\\subfolder"; our $DIR_DEV = "\\\\serverDEV\\folder\\subfolder"; . . . }elsif ($query->param('action') eq 'split' && $query->param('fileNum') ne "") { my $fileNum $query->param('fileNum'); my $fileX=$DIR_X . "\\" . $fileNum . ".txt"; my $fileY $DIR_Y . "\\" . $fileNum . ".txt"; my $fileDEV = $DIR_DEV . "\\" . $fileNum . ".txt"; my $splitNbr = $query->param('splitNbr'); my @letters1("a".. "z"); for (my $i = 0; $i < $splitNbr; $i++) { my $FileNew_X = $DIR_X . "\\" $fileNum. $letters[$i]=.txt"; my $FileNew_Y = $DIR_Y . "\\" $fileNum. $letters[$i]=.txt"; my $FileNew_DEV = $DIR_DEV . "\\" $fileNum. $letters[$i]=.txt"; copy($fileX, $FileNew_X) or die "WARNING: copy failed: $!\n"; ---->>>>>ERROR AT NEXT LINE copy($fileY, $FileNew_Y) or die "WARNING: copy failed: $!\n"; copy($fileDEV, $FileNew_DEV) or die "WARNING: copy failed: $!\n"; }
