Apparently Anaconda is ActiveStating people and this may very well prove to be a significant issue in the dominance of Python in certain data science fields. Bioinformatics is a very good example of a field that got addicted to Python and the reliance of Anaconda is coming back to bite (the post and the responses raise the prospect of nightmarish scenarios for other environment managers like conda-forge/buoconda). The immediate solution for dependency management is to dockerize everything, but many tools require individual docker containers. If you have to combine more than one of them, chances are that your path will not be a rosy one.

Although this StackOverflow question about "islands and gaps" is titularly about Perl, the SQL answers are very nice. Apparently this is a FAQ for SQL.

However, this has bugged me for years on the CPAN side, but never enough to make me really do anthing about.

I thought there was a Perl module that did this, and it was in the context of a usenet reader that would take a list of article IDs, such as 1, 2, 3, 4, 5, 7, 10, 11, 15 and return something like 1-5,7,10-11,15 as a more space-efficient store of all the articles you had read.

Every time I've looked I've stopped after 15 minutes because I get distracted and I've never really needed this except to answer someone else's question. I'm not asking how to solve this because there are plenty of algorithm tutorials out there. Surely this is on CPAN somewhere.

There are plenty of options to go the other way and to ask if a number is in one of the ranges.

• Usenet was pre-web reddit, and comp.lang.perl and comp.lang.perl.misc are where I got my start in the Perl socials before there was "social".

Perl: makes array of item ids shortened

So, I have a large set of numbers, basically 1001 .. 150000 for a database using MySQL There are a ton of gaps in the IDs on the database, so not all IDs exist. It can go from 100000 - 10500, then ...

Good afternoon, all. I have a Perl script that connects to a bunch of REST-based services via LWP::Simple. I'm running on MacOS (Perl v5.30). One of these services moved to be SSL-based. I've been struggling to find an appropriate library to use for SSL with Perl. These libraries require a certain amount of certificate management on my Mac -- and integration with Perl via environment variables or such -- and the instructions are generally sparse/obtuse. Can anybody help with this? I'm not looking to do anything particularly fancy. Just call a REST service via HTTPS. Thanks in advance for your help.

We need to be able to work with parquet files. It is a must.

For anyone cares a solution could me a native DuckDB driver. It is a pitty we do not have it.

I'm getting an SSL failure , and I can’t figure out what isn’t migrated properly from the perl setup

'auto_upgrade' => 1 }, 'Mojo::Asset::Memory' ) }, 'Mojo::Content::Single' ), 'error' => [ 'IO::Socket::SSL 1.75 required for TLS support' ], 'finished' => 3, 'state' => 'finished'

It seems to be using the same exact local Perl config but after a long time chasing I have dumped out the module includes for perl and it is failing to load the file:

$VAR475 = 'IO/Socket/SSL.pm';
$VAR476 = undef;And $VAR161 = 'Net/SSLeay.pm';
$VAR162 = undef;

Whereas on the working (current, old server)It’s printing out correctly:

$VAR479 = 'IO/Socket/SSL.pm';
$VAR480 = '/var/home/tyeeapps/support.thetyee.ca/www/local/lib/perl5/IO/Socket/SSL.pm';$VAR161 = 'Net/SSLeay.pm';
$VAR162 = '/var/home/tyeeapps/support.thetyee.ca/www/local/lib/perl5/x86_64-linux/Net/SSLeay.pm';

I've reinstalled the revelant modules from yum at the system level, which shouldn't matter. As well as on the perlbrew install in play, and in Carton, which the app is using

relevant line of code:

https://github.com/TheTyee/support.thetyee.ca/blob/e5cf4fd189ea4256c7de2a4f91303908770125a7/app.pl#L705

which does:

$res

= $ua->post( $API

. 'subscriptions' =>

{ 'Content-Type' => 'application/xml', Accept => '*/*' } =>

$transxml )->res;

}

my $xml = $res->body;

If there was a mechanism to,

• Opt-into Markdown documentation on a per-file basis.
• Document your code with Markdown instead instead of POD

Assuming these concerns were met,

• A call to perldoc MyModule rendered the Markdown to text with something like mdcat which supports images, links
• No browser was required at all (mdcat works without a browser).
• Support for terminal-rendering of Markdown was a part of core.
• All of this was done merely by creating a distinction between a code-comment, and a doc-comment as demonstrated in this repo, where
  
  • A doc comment was marked with a line starting ##
  • Any other use of # continues to carry code-commenting semantics

  
  

Would you prefer it and use it?

Perl is growing and adapting to the modern times, just like a new shiny Plug-In Hybrid car. Plug-in hybrid cars have the best of both worlds, an electric motor that has an average range of 20-60 miles and after its range is depleted it goes on the good old reliable gas motor for a few hundred miles.

Perl has many new shiny tech ( think of this as the Electric motor side of the Plug-In Hybrid car ) like Dancer2, Mojolicious , Starman and now COR which is a new OO system that is part of the language ( and many other cool new cpan modules that I might have missed * feel free to share your favorite new cpan module in the comments)

Perl has done a good job at keeping backwards compatibility ( now think of this as the gas engine side of the plugin hybrid car ) where many companies can still reliably run its perl code ( even after upgrading perl and obviously a few tweaks in the codebase here and there )

The Perl community is still active and its cpan modules continue to be maintained. Yes we have experienced a shrinking in the Perl community but the community has maintained a focus on improving the core modules that are shipped in the language and has paid close attention to widely used cpan modules ( read up on cpan river model - https://neilb.org/2015/04/20/river-of-cpan.html )

If you used to write Perl code or your curious about it then this is the best time to give Perl 5.40 a try and play around with some of its new web frameworks, cpan libraries and its new OO system COR.

Those who've been around long enough know that the use of programming languages was almost a religion a few years ago. For example, the .NET community made no secret of being a sect that branded other technologies as the devil's work. Admittedly, the Llama book was also considered a bible.

Until 20 years ago, Perl was regarded as an elite technology that one could boast about even barely mastering. Getting started with Perl was and still is tough and requires motivation. The reward for building Perl skills often comes years later when you calmly realize that even 10-year-old scripts still perform their duties perfectly - despite multiple system environment updates. Generally, even unoptimized Perl programs run more efficiently than new developments with technologies sold to us as the "hot shit."

One of Perl's top application areas is high-performance and robust web applications in mod_perl/2. To my knowledge, there's no comparable flexible programming language that can interact so closely with the web server and intervene in every layer of the delivery process. The language is mature, balanced, and the syntax is always consistent - at least for the Perl interpreter 😉 If you go to the official mod_perl page (perl.apache.org) in 2024, it recommends a manual written over 20 years ago, and even the link no longer works.

As a Perl enthusiast from the get-go and a full-stack developer, I feel today that - albeit reluctantly - I need to consider a technology switch. Currently, I'm still developing with mod_perl/2 and Perl Mason. As long as I'm working on interface projects, I'm always ahead of the game and can deliver everything in record time. However, when it comes to freelance projects or a new job, it's almost hopeless to bring in Perl experience, especially in Europe.

Throughout my career, I've also used other technologies such as Java Struts, PHP, C/C++, Visual Basic .NET, and I'd better not mention COBOL-85. I've always come back to Perl because of its stability. But I'm noticing that the language is effectively dead and hardly receives any updates or is talked about much. If I were forced to make a technology switch for developing full-stack applications, I would switch to React or Django. It's a shame.

I have been a Perl guy for 30+ years and have had the great idea to upgrade the Perl version of my large Perl APP to 5.40; after a lot of fiddeling around and overriding some Makefile.PL files I got the code and all required libraries to work on an AlmaLinux 9.4. Hoewever I am stuck on getting it to run locally on MacOS 14.5.

The two libraries currently roadblocking are Net::SSL and DBD::MariaDB. I am not fluent enough in C to understand how and if I can get things sorted; anyone able to help? Full compile errors below.

Net::SSL

Found libraries 'ssl, crypto, z' *** THIS IS NOT AN ERROR, JUST A MESSAGE FOR YOUR INFORMATION *** Do you really need Crypt::SSLeay? Starting with version 6.02 of LWP, https support was unbundled into LWP::Protocol::https. This module specifies as one of its prerequisites IO::Socket::SSL which is automatically used by LWP::UserAgent unless this preference is overridden separately. IO::Socket::SSL is a more complete implementation, and, crucially, it allows hostname verification. Crypt::SSLeay does not support this. At this point, Crypt::SSLeay is maintained to support existing software that already depends on it. However, it is possible that your software does not really depend on Crypt::SSLeay, only on the ability of LWP::UserAgent class to communicate with sites over SSL/TLS. If are using version LWP 6.02 or later, and therefore have installed LWP::Protocol::https and its dependencies, and do not explicitly use Net::SSL before loading LWP::UserAgent, or override the default socket class, you are probably using IO::Socket::SSL and do not really need Crypt::SSLeay.

Can one explain why perl is not as admired or desired as bash?

Hello,

Running CPAN behind a corporate proxy, it's not trusting the certs. The certs are installed on the machine so web browsing to https://cpan.org/r/perl/.rss works fine, but how can I modify the CPAN trust store to also trust these certs? I need to install a chain.

This is the error:

HTTP::Tiny failed with an internal error: SSL connection failed for cpan.org: SSL connect attempt failed error:0A000086:SSL routines::certificate verify failed

Thanks!

I haven't been able to use the site in the last week or so. If it loads at all, it shows a Timeout Error after 30 seconds instead. Is it broken, and how long has it been this way?

I am new to this subreddit, but not new to Perl, though I've been flirting with Python for a little over two years so I'm a little out of the loop.

If I wanted to create a RESTful API using Catalyst and have my Swagger docs generated automatically, are there any toolchain recommendations that anyone can make?

Thanks.

As you may know, the release of a new version of Perl triggers the process to elect a new Perl Steering Council. That process has been taking place over the last few weeks and the results were announced a few days ago.

Congratulations to returning members Philip Bruhat and Graham Knop and to new member Aristotle Pagaltzis. And many thanks to retiring member Paul Evans.

An analyzer has been implemented for the Perl track on exercism.org. Currently it uses Perl::Critic to give feedback when a user submits an implementation of an exercise.

The list of policies in use is quite lean at the moment, but hopefully the feedback should prove useful to newbies getting to grips with Perl!

I'm using h2xs to make glue code for a C library to a module. Imagine this scenario in the C header:

struct foo; struct foo * new_foo(); void set_foo_member(struct foo * f, int value); int get_foo_member(const struct foo * f); 

struct foo * new_foo() int get_foo_member(f) const struct foo * f void set_foo_member(f, value) struct foo * f int value 

const struct foo * T_PTROBJ struct foo * T_PTROBJ 

my $foo = new_foo(); $foo->set_foo_member(123); print "Foo member is: " . $foo->get_foo_member(); 

get_foo_member: Expected f to be of type const struct FooPtr; got struct FooPtr=SCALAR(0x2ecd9c2dd768) instead at ... 

What's the solution here? Do I remove all const keywords in my XS code? Is there some switch or setting to make xsubpp treat both as the same type? Something else?

I have a Perl script that takes several hours to run, I need to know when it's done, but I sometimes forget to keep checking.

It's running on Strawberry in Windows Server 2019. How easy would it be to write another script to send an email? I could run them as a batch I'm thinking.

I'm very weak at programming, I really only dabble.

It's gotta be me, but I'm at a loss. Installing with cpan: I can build XML::LibXML (lots of warnings) but the test suite refuses to run cleanly, staring with errors:

t/02parse.t ........................................ 1/533

# Failed test 'error parsing <!DOCTYPE X SYSTEM "example/ext\_ent.dtd">

# <X>\&foo;</X>

# '

# at t/02parse.t line 887.

# got: ''

# expected: anything else

# Looks like you failed 1 test of 533.`

and then getting worse from there.

I've installed the module on other Macs including other Intel boxes.

I've re-installed MacPorts (which is what I used to install LibXML2 and all the other prereqs).

I've built from source - same experience. Build succeeds, tests all fail.

I'm trying to figure out how to run the tests individually to see what's going on in better detail, but if anyone has seen and solved this funky issue of getting XML::LibXML to build and run cleanly on Mac OSX, please -I'd love to hear it. Everything else builds/tests/installs fine. reports does show some failed Mac builds.

I have a Mac M1 chip laptop.

While I have managed to install a couple of modules, most fail to install.

I tried perlbrew, but that was a struggle to even get it to install perl itself, but when it was installed it wasn't working the way I needed it to.

Just wondering if I am missing something with CPAN or if this is an issue because it's an M1 chip?

The final installment in the series:

"The-Quest-For-Performance" from my blog Killing It with #perl

Discussing #python #numpy #numba, #rstats #openMP enhancements of Perl code and #simd

Bottom line: I will not be migrating to Python anytime soon.

Food for thought: The Perl interpreter (and many of the modules) are deep down massive C programs. Perhaps one can squeeze real performance kicks by looking into alternative compilers, compiler flags and pragmas ?

I would be interested to know why you chose Perl and how long you have been using it and what for.

I have just returned to Perl after many years away, think decades rather than a couple of years. Consider me a noob as I've long forgotten anything I knew about the language.

I run a small home webserver, Apache on Windows 10 with Strawberry Perl, and recently started some projects starting with moving away with things like Google Analytics and going back to some old log analyzers such as AWStats, which is still being maintained, and W3Perl, which is not. Even more recently I have started using Ringlink.

Perl is still being developed, Strawberry, Active State, CPAN etc. but lost out to PHP and Python. Just like COBOL, I can easily imagine thousands of systems depend on Perl.
