Perl::Critic::Policy::Documentation::RequireEndBeforeLastPod

NAME

Perl::Critic::Policy::Documentation::RequireEndBeforeLastPod − require __END__ before POD at end of file

DESCRIPTION

This policy is part of the "Perl::Critic::Pulp" addon. It requires that you put an "__END__" before POD at the end of a file. For example,

    program_code();
    1;
    __END__     # good
    =head1 NAME
    ...

and not merely

    program_code();
    1;          # bad
    =head1 NAME
    ...

This is primarily a matter of personal preference, so the policy is low priority and only under the "cosmetic" theme (see " POLICY THEMES " in Perl::Critic). An "__END__" like this has no effect on execution, but it’s a fairly common convention since it’s a good human indication you mean the code to end there, and it stops Perl parsing through the POD which may save a few nanoseconds.

This policy is looser than "Documentation::RequirePodAtEnd" insofar as you’re allowed to have POD anywhere in among the code. The requirement is only that if the file ends with POD then you should have an "__END__" between the last code and last POD .

A file of all POD , or all code, or which ends with code, is ok. Ending with code is usual if you write your POD at the start of the file or in among the functions etc,

    =pod
    And that's all.
    =cut
    cleanup ();
    exit 0;     # good

A file using "__DATA__" is always ok, since you can’t have "__END__" followed by "__DATA__", wherever you want your POD . If the "__DATA__" is in fact "SelfLoader" code then it can helpfully have an "__END__" within it like this policy, but as of "perlcritic" version 1.092 no checks at all are applied to SelfLoader sections.

As always if you don’t care about "__END__" you can disable "RequireEndBeforeLastPod" from your .perlcriticrc in the usual way (see " CONFIGURATION " in Perl::Critic),
