README

NAME
    strictures - turn on strict and make all warnings fatal

SYNOPSIS
      use strictures 1;

    is equivalent to

      use strict;
      use warnings FATAL => 'all';

    except when called from a file where $0 matches:

      /^x?t\/.*(?:load|compile|coverage|use_ok).*\.t$/

    and when either '.git' or '.svn' is present in the current directory
    (with the intention of only forcing extra tests on the author side) - or
    when the PERL_STRICTURES_EXTRA environment variable is set, in which
    case

      use strictures 1;

    is equivalent to

      use strict;
      use warnings FATAL => 'all';
      no indirect 'fatal';
      no multidimensional;
      no bareword::filehandles;

    Note that _EXTRA may at some point add even more tests, with only a
    minor version increase, but any changes to the effect of 'use
    strictures' in normal mode will involve a major version bump.

    Be aware: THIS MEANS THE EXTRA TEST MODULES ARE REQUIRED FOR AUTHORS OF
    STRICTURES USING CODE - but not by end users thereof.

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 '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, strictures turns on indirect checking only when it thinks
    it's running in a compilation (or pod coverage) test - though if this
    causes undesired behaviour this can be overridden by setting the
    PERL_STRICTURES_EXTRA environment variable.

    If additional useful author side checks come to mind, I'll add them to
    the _EXTRA code path only - this will result in a minor version increase
    (i.e. 1.000000 to 1.001000 (1.1.0) or similar). Any fixes only to the
    mechanism of this code will result in a subversion increas (i.e.
    1.000000 to 1.000001 (1.0.1)).

    If the behaviour of 'use strictures' in normal mode changes in any way,
    that will constitute a major version increase - and the code already
    checks when its version is tested to ensure that

      use strictures 1;

    will continue to only introduce the current set of strictures even if
    2.0 is installed.

METHODS
  import
    This method does the setup work described above in "DESCRIPTION"

  VERSION
    This method traps the strictures->VERSION(1) call produced by a use line
    with a version number on it and does the version check.
