=head1 NAME
Dist::Metadata::Struct - Enable Dist::Metadata for a data structure
=head1 VERSION
version 0.925
=head1 SYNOPSIS
my $dm = Dist::Metadata->new(struct => {
files => {
'lib/Mod.pm' => 'package Mod; sub something { ... }',
'README' => 'this is a fake dist, useful for testing',
}
});
=head1 DESCRIPTION
This is a subclass of L<Dist::Metadata::Dist>
to enable mocking up a dist from perl data structures.
This is mostly used for testing
but might be useful if you already have an in-memory representation
of a dist that you'd like to examine.
It's probably not very useful on it's own though,
and should be used from L<Dist::Metadata/new>.
=head1 METHODS
=head2 new
$dist = Dist::Metadata::Struct->new(files => {
'lib/Mod.pm' => 'package Mod; sub something { ... }',
});
Accepts a C<files> parameter that should be a hash of
C<< { name => content, } >>.
Content can be a string, a reference to a string, or an IO object.
=head2 default_file_spec
C<Unix> is the default for consistency/simplicity
but C<file_spec> can be overridden in the constructor.
=head2 file_content
Returns the string content for the specified name.
=head2 find_files
Returns the keys of the C<files> hash.
