=head1 NAME
strictures - turn on strict and make all warnings fatal
=head1 SYNOPSIS
use strictures 2;
is equivalent to
use strict;
use warnings FATAL => 'all';
use warnings NONFATAL => qw(
exec
recursion
internal
malloc
newline
experimental
deprecated
portable
);
no warnings 'once';
except when called from a file which matches:
(caller)[1] =~ /^(?:t|xt|lib|blib)[\\\/]/
and when either C<.git>, C<.svn>, or C<.hg> is present in the current directory
(with the intention of only forcing extra tests on the author side) -- or when
C<.git>, C<.svn>, or C<.hg> is present two directories up along with
C<dist.ini> (which would indicate we are in a C<dzil test> operation, via
L<Dist::Zilla>) -- or when the C<PERL_STRICTURES_EXTRA> environment variable is
set, in which case it also does the equivalent of
no indirect 'fatal';
no multidimensional;
no bareword::filehandles;
Note that C<PERL_STRICTURES_EXTRA> may at some point add even more tests, with
only a minor version increase, but any changes to the effect of C<use
strictures> in normal mode will involve a major version bump.
If any of the extra testing modules are not present, L<strictures> will
complain loudly, once, via C<warn()>, and then shut up. But you really
should consider installing them, they're all great anti-footgun tools.
=head1 DESCRIPTION
I've been writing the equivalent of this module at the top of my code for
about a year now. I figured it was time to make it shorter.
Things like the importer in C<use Moose> don't help me because they turn
warnings on but don't make them fatal -- which from my point of view is
useless because I want an exception to tell me my code isn't warnings-clean.
Any time I see a warning from my code, that indicates a mistake.
Any time my code encounters a mistake, I want a crash -- not spew to STDERR
and then unknown (and probably undesired) subsequent behaviour.
I also want to ensure that obvious coding mistakes, like indirect object
syntax (and not so obvious mistakes that cause things to accidentally compile
as such) get caught, but not at the cost of an XS dependency and not at the
cost of blowing things up on another machine.
Therefore, L<strictures> turns on additional checking, but only when it thinks
it's running in a test file in a VCS checkout -- although if this causes
undesired behaviour this can be overridden by setting the
C<PERL_STRICTURES_EXTRA> environment variable.
If additional useful author side checks come to mind, I'll add them to the
C<PERL_STRICTURES_EXTRA> code path only -- this will result in a minor version
increase (e.g. 1.000000 to 1.001000 (1.1.0) or similar). Any fixes only to the
mechanism of this code will result in a sub-version increase (e.g. 1.000000 to
1.000001 (1.0.1)).
=head1 CATEGORY SELECTIONS
strictures does not enable fatal warnings for all categories.
=over 4
=item exec
Includes a warning that can cause your program to continue running
unintentionally after an internal fork. Not safe to fatalize.
