Perl::Critic::Policy::Documentation::RequireEndBeforeLastPod - require __END__ before POD at end of file
This policy is part of the
Perl::Critic::Pulp add-on. It requires that you put an
__END__ before POD which is 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 severity 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. This policy allows POD to be 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, 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),
