=head1 NAME

Perl::Critic::Utils::Constants - Global constants.

=head1 DESCRIPTION

Defines commonly used constants for L<Perl::Critic|Perl::Critic>.


=head1 INTERFACE SUPPORT

This is considered to be a public module.  Any changes to its
interface will go through a deprecation cycle.


=head1 IMPORTABLE CONSTANTS

=over

=item C<$PROFILE_STRICTNESS_WARN>

=item C<$PROFILE_STRICTNESS_FATAL>

=item C<$PROFILE_STRICTNESS_QUIET>

=item C<$PROFILE_STRICTNESS_DEFAULT>

=item C<%PROFILE_STRICTNESSES>

Valid values for the L<perlcritic/"-profile-strictness"> option.
Determines whether recoverable problems found in a profile file appear
as warnings, are fatal, or are ignored.
C<$PROFILE_STRICTNESS_DEFAULT> is set to C<$PROFILE_STRICTNESS_WARN>.
Importable via the C<:profile_strictness> tag.


=item C<$PROFILE_COLOR_SEVERITY_HIGHEST_DEFAULT>

Default for the -color-severity-highest option. Importable via the
C<:color_severity> tag.

=item C<$PROFILE_COLOR_SEVERITY_HIGH_DEFAULT>

Default for the -color-severity-high option. Importable via the
C<:color_severity> tag.

=item C<$PROFILE_COLOR_SEVERITY_MEDIUM_DEFAULT>

Default for the -color-severity-medium option. Importable via the
C<:color_severity> tag.

=item C<$PROFILE_COLOR_SEVERITY_LOW_DEFAULT>

Default for the -color-severity-low option. Importable via the
C<:color_severity> tag.

=item C<$PROFILE_COLOR_SEVERITY_LOWEST_DEFAULT>

Default for the -color-severity-lowest option. Importable via the
C<:color_severity> tag.

=item C<@STRICT_EQUIVALENT_MODULES>

=item C<@WARNINGS_EQUIVALENT_MODULES>

As the names suggest, these are lists of modules that are equivalent to
applying the L<strict|strict> or L<warnings|warnings> pragma when loaded. At
the moment, both lists are exactly the same. B<Note:> These lists are not
exhaustive; they only include the most commonly used modules. Policies that
use these lists should permit configuration of additional modules.
