=head1 NAME
Dpkg::Control - parse and manipulate official control-like information
=head1 DESCRIPTION
The Dpkg::Control object is a smart version of L<Dpkg::Control::Hash>.
It associates a type to the control information. That type can be
used to know what fields are allowed and in what order they must be
output.
The types are constants that are exported by default. Here's the full
list:
=over 4
=item CTRL_UNKNOWN
This type is the default type, it indicates that the type of control
information is not yet known.
=item CTRL_TMPL_SRC
Corresponds to the first source package stanza in a F<debian/control> file in
a Debian source package.
=item CTRL_TMPL_PKG
Corresponds to subsequent binary package stanza in a F<debian/control> file
in a Debian source package.
=item CTRL_REPO_RELEASE
Corresponds to a F<Release> file in a repository.
=item CTRL_REPO_SRC
Corresponds to a stanza in a F<Sources> file of a source package
repository.
=item CTRL_REPO_PKG
Corresponds to a stanza in a F<Packages> file of a binary package
repository.
=item CTRL_DSC
Corresponds to a .dsc file of a Debian source package.
=item CTRL_DEB
Corresponds to the F<control> file generated by dpkg-gencontrol
(F<DEBIAN/control>) and to the same file inside .deb packages.
=item CTRL_FILE_BUILDINFO
Corresponds to a .buildinfo file.
=item CTRL_FILE_CHANGES
Corresponds to a .changes file.
=item CTRL_FILE_VENDOR
Corresponds to a vendor file in $Dpkg::CONFDIR/origins/.
=item CTRL_FILE_STATUS
Corresponds to a stanza in dpkg's F<status> file ($Dpkg::ADMINDIR/status).
=item CTRL_CHANGELOG
Corresponds to the output of dpkg-parsechangelog.
=item CTRL_COPYRIGHT_HEADER
Corresponds to the header stanza in a F<debian/copyright> file in
machine readable format.
=item CTRL_COPYRIGHT_FILES
Corresponds to a files stanza in a F<debian/copyright> file in
machine readable format.
=item CTRL_COPYRIGHT_LICENSE
Corresponds to a license stanza in a F<debian/copyright> file in
machine readable format.
=item CTRL_TESTS
Corresponds to a source package tests control file in F<debian/tests/control>.
=item CTRL_INFO_SRC
Deprecated alias for CTRL_TMPL_SRC.
=item CTRL_INFO_PKG
Deprecated alias for CTRL_TMPL_PKG.
=item CTRL_PKG_SRC
Deprecated alias for CTRL_DSC.
=item CTRL_PKG_DEB
Deprecated alias for CTRL_DEB.
=item CTRL_INDEX_SRC
Deprecated alias for CTRL_REPO_SRC.
=item CTRL_INDEX_PKG

=head1 METHODS
All the methods of L<Dpkg::Control::Hash> are available. Those listed below
are either new or overridden with a different behavior.
=over 4
=item $c = Dpkg::Control->new(%opts)
Create a new deb822 control object.
Options:
=over
=item B<type>
Set the deb822 control type, used to setup default values for other options.
=back
See set_options() for more details.
=cut

    my ($this, %opts) = @_;
    my $class = ref($this) || $this;
    my $self = Dpkg::Control::Hash->new();
    bless $self, $class;
    $self->set_options(%opts);
    return $self;
}
HideShow 49 lines of Pod
=item $c->set_options(%opts)
Changes the value of one or more options.
Options:
=over
=item B<type>
Sets the deb822 control object type, used to define default values for others
options.
The output order is also set to match the ordered list returned by
Dpkg::Control::Fields::field_ordered_list($type).
=item B<name>
Sets a textual description of the type of control information.
=item B<allow_pgp>
Sets whether the parser accepts OpenPGP signatures around the deb822
control information.
By default it is set to 1 for CTRL_DSC, CTRL_FILE_CHANGES and
CTRL_REPO_RELEASE and to 0 otherwise.
=item B<allow_duplicate>
Sets whether the parser allows duplicate fields in deb822 control information.
=item B<keep_duplicate>
Sets whether the parser will keep values for duplicate fields found in
deb822 control information (when B<allow_duplicate> is enabled),
as array references.
=item B<drop_empty>
Sets whether empty fields are dropped during output.
By default it is set to 0 for CTRL_TMPL_SRC and CTRL_TMPL_PKG and
to 1 otherwise.
