A shell (like Bash) provides built-in commands and scripting features to easily solve and automate various tasks. External commands like grep, sed, Awk, sort, find, or parallel can be combined to work with each other. Sometimes you can use Perl either as a single replacement or a complement to them for specific use cases.

Perl is the most robust portable option for text processing needs. Perl has a feature rich regular expression engine, built-in functions, an extensive ecosystem, and is quite portable. However, Perl may have slower performance compared to specialized tools and can be more verb…

If you’re reading this article, you’re likely looking for a simple way to download and install the Perl programming language. Or you already have Perl installed as part of your operating system, but it’s older than the currently-supported versions (5.32.1 or 5.30.3) and you’d like to use the latest and greatest features. The download options may seem daunting, especially if you’re new to computers or programming. We’ll take things step by step, and soon you’ll be on your way to…

Paul “LeoNerd” Evans is a CPAN author, blogger, and core Perl contributor. He introduced the experimental isa operator in Perl 5.32 and the try/catch syntax in an upcoming version.

Lets see—I’m going to do this in reverse chronological order.

Currently I’m a self-employed contractor, splitting my time between Perl and other computery things, and electronics. Most of the jobs I’ve had before I did that were based on Perl, with the minor exception of a little Internet startup company called &ldqu…

Before I became a computer programmer, I tried my hand at being a human programmer, in the form of a wordsmith, as I called myself then. I had various jobs as a writer, editor, translator and journalist, but I met with little success, for two main reasons. In those days you needed a publisher to find your work interesting enough to publish before anyone could read it, and that was a pretty high bar. And in the second place, it was difficult to get the humans to react to the content I wrote (I’m still exercised that the movie reviewer would get more letters to the editor than I did after…

For a week we lost control of the Perl.com domain. Now that the incident has died down, we can explain some of what happened and how we handled it. This incident only affected the domain ownership of Perl.com and there was no other compromise of community resources. This website was still there, but DNS was handing out different IP numbers.

First, this wasn’t an issue of not renewing the domain. That would have been a better situation for us because there’s a grace period.

Second, to be very clear, I’m just an editor for the website that uses the Perl.com domain. This means that I’m…

Perl uses a simple form of garbage collection (GC) called reference counting. Every variable created by a Perl program has a refcnt associated with it. If the program creates a reference to the variable, Perl increments its refcnt. Whenever Perl exits a block it reclaims any variables that belong to the block scope. If any are references, their referenced values’ refcnt are either decremented or they’re reclaimed as well if no other references to them remain.

Reference counting has some nice properties. As GC is deterministic, it is usually not a cause of variable program performance fr…

The Perl Foundation is among the thirty open-source software organizations that Google has chosen to participate in 2021's Season of Docs program. Through this program, Google will fund a comprehensive audit of Perl's core documentation collection, a project proposed by Jason McIntosh earlier this year.

For this project a hired expert will perform a gap analysis of the documentation's content and presentation. This work will compare the documentation's present state with Perl 7's goal to put a new focus on newcomers--while retaining the docs' role as a thorough reference for all programmers.

The Perl Foundation kicked off 2021 with a survey to find out how we (both the Perl Foundation and the broader Perl community) can make Perl more welcoming to beginners. In this blog we: * Describe who responded to the survey. * Summarise the types of support they need. * Explain the work TPF is now undertaking to address these needs. * Explain how you can help, and how the TPF can support you. * A link to the raw data (minus email addresses).

Of the 513 respondents, 454 (88.5%) said they would welcome more support. For the purposes of this blog, we’re respon…

March didn't see me doing that many grant hours; I was keeping my keyboard time down for the first half of the month, and then had a lot to catch up on in the second half (and still needed to avoid putting in more than a usual working day). On the upside, the time that was spent was productive: I got some way into implementing more of Raku's multiple dispatch semantics in terms of the new dispatcher. I've written a blog post about that work (although some of the work it covers was done during April).

Dear TPF Board members,

We want to express our disappointment with the recent transparency reports and associated actions from the Community Affairs Team (CAT).

On Monday 19th March, a first Transparency Report was issued, which said that an individual had been investigated for (1) behaviour on IRC and Twitter, and (2) behaviour at a Perl event in 2019. The report also reported that they had "found many instances of communication which alone may not have constituted unacceptable behavior, but when taken together did constitute unacceptable behavior", but no further details were given on those.

Thanks for your support and encouragement ...

I had many ups and downs in the month of April. In all these, I have recieved plenty of supporting voices.

First, we had the start of Ramadan. I feel fortunate to be able to fast in this holy month. However I had to break my fast for two days because I suffered by Vertigo. Luckily I recovered very fast, thanks to ALLAH s.w.t.

As you all know, I have started taking part in the weekly challenge after rather a long break. Although I am only sharing solutions in Perl for the time being. Soon, I would start doing in Raku and Swift. Having said, I started l…

Gee almost a year since my lat post. I better start posting again or Mohammad will catch up with me ;).

Been quite a year for every one on this big blue marble. I hope you are all good.

Ok here is the very short post for today.

I just did my first build and upload of PAWS to CPAN

Expect Version 0.43 to be up there later today some time.

It was a bit of an epic on my part as this whole releasing thingy, made some real bad goofs (deleting then checking in a folder), thank goodness for 'git revert' and getting the version number wrong.

Hopefully is comes out ok.

Look for more releases in the future.

Two weeks ago, we learned that the CPAN Request Tracker was closing down early next year. I proposed a plan that CPAN authors could follow to ensure that their users can still find somewhere to report bugs in modules (and, perhaps more importantly, to see what bugs have already been reported in modules).

But that’s only part of the problem. In fact, it’s probably a minor part of the problem. If you’re an active CPAN author, then you probably already knew about the impending closure and had already made plans to deal with it. It’s likely that you had already moved your bug tracking to a new syst…

CPAN RT is going away. CPAN authors have until the beginning of March to extract any useful information from it.

RT is the “Request Tracker”, a bug tracking system that is written by Best Practical. For almost as long as I can remember, anyone who uploads a module to CPAN gets a free ticket queue for their module at rt.cpan.org. MetaCPAN assumes that’s where people should report bugs in your module and helpfully adds an “issues” link that goes to the appropriate page in RT.

But now that system is going away. It will be switched off on the 1st March 2021. The Perl NOC team is spread pretty thinly…

Blog posts are like busses. You wait months for one and then two come along on consecutive days!

Yesterday I wrote about how we didn’t need a blogging platform for the Perl community – all we really needed was a good-looking feed aggregator. I mentioned Perlsphere as one such aggregator.

Then Matthew commented, saying that Perlsphere looked a bit broken as Dave Cantrell’s posts from a few years ago frequently pop up there as new posts. I had a quick look at the problem and couldn’t quite work out what was going on. His web feed seems valid, but Perlsphere didn’t seem to recognise the dates of th…

I think it was at YAPC Copenhagen in 2008 that a small group of us first discussed the idea of building a shared blogging platform for the Perl community. It was over a year later that we launched blogs.perl.org.

I remember a lot of discussions over that time where we tried to thrash out exactly what we wanted to build. I know that one of my main drivers was that I wanted to replace the journals feature of use.perl. For those of you too young to remember, use.perl was a Perl community web site from the dawn of time. The site ran Perl news on its front page, but users could also have their own j…

Last week I was in Riga for this year’s European PerlCon (the conference formerly known as YAPC::Europe). As has become traditional, here’s my report of the conference.

My conference began on Tuesday night at the pre-conference meet-up. Most people get into town on the night before the conference starts and the organisers always designate a local bar as a meeting place. This time, as the conference was being held in a hotel, the meeting place was a room in the hotel just outside the main conference room. It’s always good to meet up with friends who you might not have seen since the previous con…

Today I was invited to join Gabor Szabo for a live pair programming session, where we worked on adding Docker and CI to his course management application. You can view the video of our informal competition who is the worst typist here.

At first I was bit skeptical about the concept of live coding (who wants to watch people google^w code for two hours?), but in the end it was a funny and informative (for me) session. Maybe I'm just totally deprived of live human interaction (thanks, Corona), but I think I'd enjoy similar sessions also under normal circumstances.

During the great RT will be shutdown craze earlier this year, I updated my Dist::Zilla setup to use a custom author bundle (Dist::Zilla::PluginBundle::Author::DOMM) so I can unify my Dist::Zilla config in one place (instead of copying dist.ini from project to project, adding & modifying it from time to time, but never backporting improvements to older projects).

Two of my decisions might have been not too smart (as indicated by various pull requests), so I'm now looking for feedback...

I stopped generating META.yml files and now only generate META.json. As far as I can tell…

In some regards, I'm a very old school person. For example I do not like the concept of streaming audio (via Spotify et.al.). I want MP3s on my hard disk (and/or vinyl on my record player). I want access to my music when I'm offline (and I'm offline a lot) and without using a so-called smart phone (I prefer vintage USB-stick MP3 players). My partner thinks the same (I guess 25+ years of my propaganda had some influence..).

But "modern" sites make it rather hard to actually download content (even if it's free). They offer links to a myriad of apps, but often no download button. At least a lot of…

This was another fun one. It took me some time to get the logic right (or left?), but in the end I came up with a nice solution. BTW, this will be the last daily blog post, as I'll have to finish some work projects, and start with some holiday projects.

Today I needed quite a bit of code, so let's split it up:

I have for some time been the maintainer of the Perl distribution: Crypt::OpenSSL::X509. The implementation is a wrapper on the OpenSSL C libraries, relying on XS.

I took over the maintenance from Dan Sully, because we where using the distribution at work and it need some maitaining. O am not a C-programmer, XS wizard or compiler expert - anyway I thought I could learn something from taking on the maintainer role.

Over time I have made releases, when there was something obvious or somebody sent PRs to the repository.

Release 1.54 has been released, but I could not find the time to write a proper announcement, so with some delay here goes.

The release is a minor feature release, in adds a few improvements in regard to making some APIs public, promoting these from private APIs (please see the Change log below for details). The private APIs are kept intact for backwards compatibility, in case somebody has implementations relying on these.

Also the documentation has had some improvements, in regard to removal of parts, which made no sense based. It might have been design notes more than actual implementation doc…

Challenge, My solutions

You are given a string path, starting with a slash /.

Write a script to convert the given absolute path to the simplified canonical path.

Outside the challenge, I would use the swiss army-knife of Path::Tiny to do this. Regularly readers of my blog post will know that I don't use modules outside Perl core in completing a task.

Therefore I split the supplied path by each forward slash into @parts. I then take three actions depending on the part.

• If it is empty, do nothing. This handles the first slash, the trailing slash, and any…

Let’s assume for the moment that you’re writing a Perl module or application. You’d like to maintain some level of software quality (or kwalitee), so you’re writing a suite of test scripts. Whether you’re writing them first (good for you for practicing test-driven development!) or the application code is already there, you’ll probably be reaching for Test::Simple, Test::More, or one of the Test2::Suite bundles. With the latter two you’re immediately confronted with a choice: do you count up the number of tests into a plan, or do you forsake that in favor of leaving a done_testing() call at the…

Modules (and CPAN) are one of the "killer feature" of Perl, this article will discuss module loading/calling and some subtleties around this topic.

It is something important to understand early when you learn Perl programming, how you will load a module does not dictate its future package name (how it will be called).

Let's start with a simple example with a empty module stored in a File.pm in a subdirectory:

Directory
└── Directory
    └── File.pm

File.pm contains nothing but a true return value:

1;

The import is done by pointing to the path…

There are times when I am confused by the context of Perl. I wrote a tool to reduce this confusion.

If you plug in the contextual_diag subroutine where you want to know Perl context, it will alert you to the context.

The following code explores the context when evaluating the value of a hash reference:

use Contextual::Diag;

# Here...
my $a = { key => 'value' };

# Do this...
my $a = { key => contextual_diag 'value' };

# Then this happens!
# => wanted LIST context

In Contextual::Diag, the first step is to use…

Back when we started this service, it filled a need by providing a place for CPAN authors to track bug reports and feature requests. In recent years github.com and other sites have added issue tracking to their git repo hosting and many CPAN authors have migrated to these sites.

Back in mid-November 2020, I noticed that Hackage (the Haskell package repository) probably has roughly the same daily upload rate as CPAN, or even higher.

Since the Hackage API does not provide a way to list releases (uploads), I had to download the recent additions page periodically, parse each page, and merge the results into a single large list. Because I have just collected the recent additions page since mid-November, I'm looking at December 2020 period.
