NAME

Perl::ToPerl6::Annotation - A "## no mogrify" annotation in a document.

SYNOPSIS

use Perl::ToPerl6::Annotation;
$annotation = Perl::ToPerl6::Annotation->new( -element => $no_mogrify_ppi_element );

$bool = $annotation->disables_line( $number );
$bool = $annotation->disables_policy( $policy_object );
$bool = $annotation->disables_all_transformers();

($start, $end) = $annotation->effective_range();
@disabled_policy_names = $annotation->disabled_transformers();

DESCRIPTION

Perl::ToPerl6::Annotation represents a single "## no mogrify" annotation in a PPI:Document. The Annotation takes care of parsing the annotation and keeps track of which lines and Policies it affects. It is intended to encapsulate the details of the no-mogrify annotations, and to provide a way for Transformer objects to interact with the annotations (via a Perl::ToPerl6::Document).

INTERFACE SUPPORT

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

CLASS METHODS

create_annotations( -doc => $doc )

Given a Perl::ToPerl6::Document, finds all the "## no mogrify" annotations and constructs a new Perl::ToPerl6::Annotation for each one and returns them. The order of the returned objects is not defined. It is generally expected that clients will use this interface rather than calling the Perl::ToPerl6::Annotation constructor directly.

CONSTRUCTOR

new( -element => $ppi_annotation_element )

Returns a reference to a new Annotation object. The -element argument is required and should be a PPI::Token::Comment that conforms to the "## no mogrify" syntax.

METHODS

disables_line( $line )

Returns true if this Annotation disables $line for any (or all) Policies.

disables_policy( $policy_object )

disables_policy( $policy_name )

Returns true if this Annotation disables $polciy_object or $policy_name at any (or all) lines.

disables_all_transformers()

Returns true if this Annotation disables all Policies at any (or all) lines. If this method returns true, disabled_transformers will return an empty list.

effective_range()

Returns a two-element list, representing the first and last line numbers where this Annotation has effect.

disabled_transformers()

Returns a list of the names of the Policies that are affected by this Annotation. If this list is empty, then it means that all Policies are affected by this Annotation, and disables_all_transformers() should return true.

element()

Returns the PPI::Element where this annotation started. This is typically an instance of PPI::Token::Comment.
