NAME

Perl::Critic::Pulp - some add-on perlcritic policies

DESCRIPTION

This is a collection of add-on policies for Perl::Critic, summarized below. They're under a "pulp" theme plus other themes according to their purpose (see "POLICY THEMES" in Perl::Critic).

Roughly half are code related and half cosmetic. You can always enable or disable the ones you do or don't want. It's normal to pick and choose things reported. There's a lot of perlcritic policies both built-in and add-on and they range from helpful things catching problems through to the bizarre or restrictive, and in some cases mutually contradictory! Many are only intended as building blocks for enforcing a house style. If you try to pass everything then you'll give away big parts of the language, so if you're not turning off or customizing about half then you're either not trying or you're much too easily lead!

Documentation

Avoid C<> in NAME section, bad for man's "apropos" output.

Documentation::ProhibitVerbatimMarkup

Verbatim paragraphs not expanding C<> markup etc.

Documentation::RequireLinkedURLs

Use L<> markup on URLs.

OTHER NOTES

In most of the perlcritic documentation, including the Pulp stuff here, policy names appear without the full Perl::Critic::Policy::... class part. In Emacs try man-completion.el to have M-x man automatically expand a suffix part at point, or ffap-perl-module.el to go to the source similarly.

http://user42.tuxfamily.org/ffap-perl-module/index.html

In perlcritic's output you can ask for %P for the full policy name to copy or follow. Here's a good format you can put in your .perlcriticrc, including file:line:column: style Emacs will recognise.

verbose=%f:%l:%c:\n %P\n %m\n

See Perl::Critic::Violation for all the % escapes. perlcritic.el has patterns for Emacs to match the builtin perlcritic formats, but it's easier to print file:line:column:.
