@mjg @coocook @metacpan @demiguise #Perl 5.42 is now available on Docker Hub! 🎉

https://hub.docker.com/_/perl

Merged 42 minutes ago as I write this 😎

#DockerHub

Great stuff! (Of course #perl has had that all along :p )

Here’s another information-packed #Perl weekly newsletter, enjoy!

@metacpan Maybe this adds to the saying that you should never release on Fridays. That might be true for programming languages as well.

#Perl #Friday #FridayRelease

@demiguise @coocook As @dboehmer said but didn’t tag you two, since #Perl’s is an official #Docker image it’s a two-step process. We are now waiting on this PR before v5.42.0 is available on #DockerHub.

@metacpan I have seen that before but took another look. The PR was already merged 2 days ago but it seems we’re now waiting for #Docker themselves to merge this followup PR:
https://github.com/docker-library/official-images/pull/19396

It’s been opened on Friday after 8pm so it probably isn’t going to be handled over the weekend. Hopefully we’ll have #Perl 5.42 by Monday.

I've uploaded a new version of Test::Mixed scripts to #CPAN. It's for #security testing #Perl distributions for mixed #unicode scripts.

The latest version supports testing for just 7-bit ASCII.

I've uploaded a new #Perl utility to #CPAN for writing author tests. It gathers a list of files in a distribution.

https://metacpan.org/dist/Test2-Util-DistFiles

The motivation is to avoid repeating the code in author and release testing modules all do.

Why do I keep making subtle mistakes on uploading CPAN modules!

What are your tips on creating a FOSS release without unwanted/wrong information?

I just uploaded Math-Permutation-0.0211, this is the third release I made within two days. Then I found the licensing info on README text file is incorrect. The mistake was made because I recreated the folder structure by Module-Starter, because I kept getting MYMETA.yml and MYMETA.json after "perl Makefile.PL; make". On Math-Permutation-0.0210, I found the MANIFEST text file has an unwanted listing "Math-Permutation-0.0201.tar.gz" .

I was slightly too young in my career to really get to use #perl professionally. I know more ruby than I do perl. I really have always secretly wanted to learn it but I can never come up with a problem to solve with it

I wrote a little tool to show what "board.*" defines for a #CircuitPython build. I got tired for always trawling through ports/*/boards for it. It's called "cirpy-showpins" and its output looks like the below. I used #Perl originally but here's it in Python: https://gist.github.com/todbot/e91853b9d5e021405bb9a85081a39163

@metacpan How long does it take #DockerHub to pick up #Perl 5.42? The Pull Request is merged but there’s no mention of 5.42 on Docker Hub yet:
https://hub.docker.com/_/perl

I’ve introduced a new contributor to @coocook today and we’ve been working on it all day. Yesterday I was glad to install 5.42 via Perlbrew just 1 day before today 🤩

Unfortunately our feature branch to upgrade to Perl 5.42 failed in CI because that image is not yet available 😔

PWC 328 is about replacing strings, and calling one of the problems "Good" made me think of a song my wife claims is mostly forgotten by mainstream fans of Queen: Good Old-Fashioned Lover Boy. So let's crank out some good old-fashioned code. #PerlWeeklyChallenge #raku #perl #python #elixir
