=head1 NAME

Perl::Critic::OptionsProcessor - The global configuration default values, combined with command-line values.


=head1 DESCRIPTION

This is a helper class that encapsulates the default parameters for
constructing a L<Perl::Critic::Config|Perl::Critic::Config> object.
There are no user-serviceable parts here.


=head1 INTERFACE SUPPORT

This is considered to be a non-public class.  Its interface is subject
to change without notice.


=head1 CONSTRUCTOR

=over

=item C< new( %DEFAULT_PARAMS ) >

Returns a reference to a new C<Perl::Critic::OptionsProcessor> object.
You can override the coded defaults by passing in name-value pairs
that correspond to the methods listed below.

This is usually only invoked by
L<Perl::Critic::UserProfile|Perl::Critic::UserProfile>, which passes
in the global values from a F<.perlcriticrc> file.  This object
contains no information for individual Policies.

=back

=head1 METHODS

=over

=item C< exclude() >

Returns a reference to a list of the default exclusion patterns.  If
onto by
L<Perl::Critic::PolicyParameter|Perl::Critic::PolicyParameter>.  there
are no default exclusion patterns, then the list will be empty.


=item C< force() >

Returns the default value of the C<force> flag (Either 1 or 0).


=item C< include() >

Returns a reference to a list of the default inclusion patterns.  If
there are no default exclusion patterns, then the list will be empty.


=item C< only() >

Returns the default value of the C<only> flag (Either 1 or 0).


=item C< profile_strictness() >

Returns the default value of C<profile_strictness> as an unvalidated
string.


=item C< single_policy() >

Returns the default C<single-policy> pattern.  (As a string.)


=item C< severity() >

Returns the default C<severity> setting. (1..5).


=item C< theme() >

Returns the default C<theme> setting. (As a string).


=item C< top() >

Returns the default C<top> setting. (Either 0 or a positive integer).


=item C< verbose() >

Returns the default C<verbose> setting. (Either a number or format
string).


=item C< color() >

Returns the default C<color> setting. (Either 1 or 0).


=item C< pager() >

Returns the default C<pager> setting. (Either empty string or the pager
command string).


=item C< allow_unsafe() >

Returns the default C<allow-unsafe> setting. (Either 1 or 0).


=item C< criticism_fatal() >

Returns the default C<criticism-fatal> setting (Either 1 or 0).

=item C< color_severity_highest() >

Returns the color to be used for coloring highest severity violations.

=item C< color_severity_high() >

Returns the color to be used for coloring high severity violations.

=item C< color_severity_medium() >

Returns the color to be used for coloring medium severity violations.

=item C< color_severity_low() >

Returns the color to be used for coloring low severity violations.

=item C< color_severity_lowest() >

Returns the color to be used for coloring lowest severity violations.

=item C< program_extensions() >

Returns a reference to the array of file name extensions to be interpreted as
representing Perl programs.
