Hey, #perl devs. Do you use DBIx::Class::Schema::Loader? Do you also use Perl::Tidy? You can get disappointed if Perl::Tidy reformats the dbic files, so drop this in your .perltidyrc to stop that:

Ignore DBIC-generated content

--format-skipping-begin='#(<<<| DO NOT MODIFY THE FIRST PART OF THIS FILE)'
--format-skipping-end='#(>>>| DO NOT MODIFY THIS OR ANYTHING ABOVE!)'

All you nutcases still using #Perl, what's actually wrong with it?

@tripleo If you want decent integration with 3rd party stuff (google APIs, amazon, etc...) you may need to write your own client stuff as most big service providers seem to have forgotten that #Perl exists

@tripleo #Perl’s “sharp edges” are mainly early syntax and features that later experience with large and networked #programming found dangerous, but are preserved for backward (and we do mean “backward”) compatibility.

See the details of the strict and warnings pragmas, and successively missing items in feature bundles:

• https://perldoc.perl.org/strict
• https://perldoc.perl.org/warnings
• https://perldoc.perl.org/feature#FEATURE-BUNDLES

Everyone! If your #business depends on #Perl or #RakuLang please consider supporting the communities you rely on!

One good way to ensure a sustainable future for #OpenSource ecosystems like these, is to support active and fertile venues for learning and teaching these technologies.

Right now, you can help by supporting the Perl and Raku Conference, and later this year, the London Perl Workshop.

Is this relevant for you? Forward it to your manager! 💯

#Copilot just wrote the following #Perl code for me, complete with the comment, which is correct.

my $UNINIT = bless => {}, 'Uninitialized::Vars::Variable';
sub uninit () { $UNINIT }
sub is_uninit ($var) { $var == $UNINIT } # XXX: This is wrong

So, I know it's sacrilege to make your own "Build System", but for fun, I decided to give it a go.

It's made up of 3 scripts:

  • build.pl: Builds the project
  • clean.pl: Cleans up artifacts
  • install.pl: Installs artifacts where they need to go in the system.

build.pl was the most complicated, but that's not saying much, it was incredibly easy to make and it's small. It even supports parallel jobs and not rebuilding an object if the source file is older than the object.

I just wasted 1hr, because I used == instead of eq and 'and' instead of && in

mjgardner,
@mjgardner@social.sdf.org avatar

@Serpent7776 use warnings; (or the -w switch for a one-line command) would have helped catch the first problem: https://perldoc.perl.org/warnings

You would then see “Argument "foo" isn't numeric in numeric eq (==)” along with the line number in the code and the string you were trying to compare instead of “foo”: https://perldoc.perl.org/perldiag#Argument-%22%25s%22-isn't-numeric%25s

If you have 2022’s version 5.36 or later, use v5.36; will enable warnings as well as other sane defaults.

@mjgardner@social.sdf.org avatar

@Serpent7776 I’m sorry to hear about the warnings lost in the output.

Since you’ve got v5.38.2, write use v5.38; and in addition to strict and warnings you enable the following niceties from https://perldoc.perl.org/feature :

bitwise
current_sub
evalbytes
fc
isa
module_true
postderef_qq
say
signatures
state
unicode_eval
unicode_strings

You’ll also disable these footgun “features”:

bareword_filehandles
indirect
multidimensional
switch

Give it a whirl!

Anyone here have experience updating a Dockerized Perl application? Specifically I am looking for help upgrading the app from 5.26 to 5.30 and how to rectify errors where some libraries (I think?) were built for Perl 5.26 and won't work under 5.30?

Started reading ‘Modern Perl’ on the train to work the other day. was the first programming language I learned, 20 years ago now, but I’ve hardly used it in probably 15 years now.

Not yet sure what I’d use it for, though. Better shell scripts? I’d normally choose Python/Ruby for that.

@profoundlynerdy@bitbang.social avatar

@benjamineskola There is a very new OOP system: https://ovid.github.io/articles/the-future-of-perl.html which looks good but I haven't actually used it myself.

I work Cybersecurity, I mostly use for quick one-off scans when someone asks me, "are we vulnerable to XYZ?" when XYZ has a (mis)configuration element to it.

A lot of my hobby code is using these days as I really enjoy the language's mutability.

You might even consider making a reasonable case to move the project’s remaining assets off #SourceForge. Impotently whinging about it here doesn’t change anything.
