cpan::meta::feature
CPAN::Meta::Feature(3) User Contributed Perl Documentation CPAN::Meta::Feature(3)
NAME
CPAN::Meta::Feature - an optional feature provided by a CPAN distribution
VERSION
version 2.120921
DESCRIPTION
A CPAN::Meta::Feature object describes an optional feature offered by a CPAN distribution and specified in the distribution's META.json (or
META.yml) file.
For the most part, this class will only be used when operating on the result of the "feature" or "features" methods on a CPAN::Meta object.
METHODS
new
my $feature = CPAN::Meta::Feature->new( $identifier => \%spec );
This returns a new Feature object. The %spec argument to the constructor should be the same as the value of the "optional_feature" entry
in the distmeta. It must contain entries for "description" and "prereqs".
identifier
This method returns the feature's identifier.
description
This method returns the feature's long description.
prereqs
This method returns the feature's prerequisites as a CPAN::Meta::Prereqs object.
BUGS
Please report any bugs or feature using the CPAN Request Tracker. Bugs can be submitted through the web interface at
http://rt.cpan.org/Dist/Display.html?Queue=CPAN-Meta <http://rt.cpan.org/Dist/Display.html?Queue=CPAN-Meta>
When submitting a bug or request, please include a test-file or a patch to an existing test-file that illustrates the bug or desired
feature.
