NAME
Perl::Critic::Policy::Documentation::RequireEndBeforeLastPod - require __END__ before POD at end of file
DESCRIPTION
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.
Disabling
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),
[-Documentation::RequireEndBeforeLastPod]
