#perlcritic — Public Fediverse posts

@regehr @commodore @dev There is even a (low-severity, a/k/a “cruel”) #PerlCritic policy to discourage everything but $_, @_, $], and numbered #RegularExpression capture variables: https://metacpan.org/pod/Perl::Critic::Policy::Variables::ProhibitPunctuationVars

https://metacpan.org/pod/Perl::Critic::Policy::Variables::ProhibitMatchVars already protects you against the performance-sapping $`, $&, and $' match variables

And you can configure your own prohibited list with https://metacpan.org/pod/Perl::Critic::Policy::Variables::ProhibitEvilVariables

#Perl #RegEx #RegExp #RegExes #RegExps

@sjn @cb 99% of the “#Perl is line noise” complaints are because of unformatted #RegularExpressions. Every language worth anything eventually supports them, but only @Perl (and #awk, earlier) makes them first-class citizens. And with Perl you can format and comment them for readability: https://perldoc.perl.org/perlretut#Embedding-comments-and-modifiers-in-a-regular-expression

We format the rest of our code for humans. Why not #regexps?

#PerlCritic can warn against bad regexps: https://metacpan.org/search?size=200&q=module%3APerl%3A%3ACritic%3A%3APolicy%3A%3ARegularExpressions
