NAME

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

DESCRIPTION

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

Compatibility::ConstantPragmaHash

Version declaration for hash style multi-constants.

Compatibility::Gtk2Constants

New enough Gtk2 version for its constants.

Compatibility::PerlMinimumVersionAndWhy

Check Perl version declared against features used.

Compatibility::PodMinimumVersion

Check Perl version declared against POD features used.

Documentation::RequireEndBeforeLastPod

Put __END__ before POD at end of file.

Miscellanea::TextDomainPlaceholders

Check args to __x, __nx, etc.

Miscellanea::TextDomainUnused

Notice Locale::TextDomain imported but not used.

Modules::ProhibitPOSIXimport

Don't import the whole of POSIX.

Modules::ProhibitUseQuotedVersion

Don't quote required version like use Foo '1.5'

ValuesAndExpressions::ConstantBeforeLt

Avoid problems with FOO < 123

ValuesAndExpressions::NotWithCompare

Avoid problems with ! $x == $y

ValuesAndExpressions::ProhibitEmptyCommas

Stray consecutive commas ,,

ValuesAndExpressions::ProhibitNullStatements

Stray semicolons ;

ValuesAndExpressions::UnexpandedSpecialLiteral

Literal use of __PACKAGE__ etc.

Roughly half are bugs and half cosmetic. You can always enable or disable the ones you do or don't want. It's normal to pick and choose what you want reported.

There's a lot of perlcritic builtin and add-on policies and they range from helpful to restrictive to bizarre and in some cases are even mutually contradictory. Many are building blocks for particular restricted house styles. If you tried to pass all you'd give away half the language. If you're not turning off or customizing up to half then either you're not trying or you're much too easily lead!

OTHER NOTES

In most of the perlcritic docs, including Pulp here, policy names appear without the full Perl::Critic::Policy::... class name. In Emacs try the author's man-completion.el to automatically get the man page from 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 paste or follow. Here's a good format you can put in your .perlcriticrc for file:line:column: which Emacs will recognise. See Perl::Critic::Violation for all the % escapes.

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

perlcritic.el has patterns to match the perlcritic builtin formats, but it's easier to print file:line:column: in the first place.
