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_INFO_SRC Corresponds to the first stanza in a F<debian/control> file in a Debian source package. =item CTRL_INFO_PKG Corresponds to subsequent 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_INDEX_SRC Corresponds to a stanza in a F<Sources> file of a source package repository. =item CTRL_INDEX_PKG Corresponds to a stanza in a F<Packages> file of a binary package repository. =item CTRL_PKG_SRC Corresponds to a .dsc file of a Debian source package. =item CTRL_PKG_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 package tests control file in F<debian/tests/control>. =back =head1 METHODS All the methods of Dpkg::Control::Hash are available. Those listed below are either new or overridden with a different behaviour. =over 4 =item $c = Dpkg::Control->new(%opts) If the "type" option is given, it's used to setup default values for other options. See set_options() for more details. =cut sub new { my ($this, %opts) = @_; my $class = ref($this) || $this; my $self = Dpkg::Control::Hash->new(); bless $self, $class; $self->set_options(%opts); return $self; } =item $c->set_options(%opts) Changes the value of one or more options. If the "type" option is changed, it is used first to define default values for others options. The option "allow_pgp" is set to 1 for CTRL_PKG_SRC, CTRL_FILE_CHANGES and CTRL_REPO_RELEASE and to 0 otherwise. The option "drop_empty" is set to 0 for CTRL_INFO_PKG and CTRL_INFO_SRC and to 1 otherwise. The option "name" is set to a textual description of the type of control information. The output order is also set to match the ordered list returned by Dpkg::Control::Fields::field_ordered_list($type). =cut sub set_options { my ($self, %opts) = @_; if (exists $opts{type}) { my $t = $opts{type}; $$self->{allow_pgp} = ($t & (CTRL_PKG_SRC | CTRL_FILE_CHANGES | CTRL_REPO_RELEASE)) ? 1 : 0; $$self->{drop_empty} = ($t & (CTRL_INFO_PKG | CTRL_INFO_SRC)) ? 0 : 1; if ($t == CTRL_INFO_SRC) { $$self->{name} = g_('general section of control info file'); } elsif ($t == CTRL_INFO_PKG) { $$self->{name} = g_("package's section of control info file"); } elsif ($t == CTRL_CHANGELOG) { $$self->{name} = g_('parsed version of changelog'); } elsif ($t == CTRL_COPYRIGHT_HEADER) { $$self->{name} = g_('header stanza of copyright file'); } elsif ($t == CTRL_COPYRIGHT_FILES) { $$self->{name} = g_('files stanza of copyright file'); } elsif ($t == CTRL_COPYRIGHT_HEADER) { $$self->{name} = g_('license stanza of copyright file'); } elsif ($t == CTRL_TESTS) { $$self->{name} = g_("package's tests control file"); } elsif ($t == CTRL_REPO_RELEASE) { $$self->{name} = sprintf(g_("repository's %s file"), 'Release'); } elsif ($t == CTRL_INDEX_SRC) { $$self->{name} = sprintf(g_("stanza in repository's %s file"), 'Sources'); } elsif ($t == CTRL_INDEX_PKG) { $$self->{name} = sprintf(g_("stanza in repository's %s file"), 'Packages'); } elsif ($t == CTRL_PKG_SRC) { $$self->{name} = sprintf(g_('%s file'), '.dsc'); } elsif ($t == CTRL_PKG_DEB) { $$self->{name} = g_('control info of a .deb package'); } elsif ($t == CTRL_FILE_BUILDINFO) { $$self->{name} = g_('build information file'); } elsif ($t == CTRL_FILE_CHANGES) { $$self->{name} = sprintf(g_('%s file'), '.changes'); } elsif ($t == CTRL_FILE_VENDOR) { $$self->{name} = g_('vendor file'); } elsif ($t == CTRL_FILE_STATUS) { $$self->{name} = g_("stanza in dpkg's status file"); } $self->set_output_order(field_ordered_list($opts{type})); } # Options set by the user override default values $$self->{$_} = $opts{$_} foreach keys %opts; } =item $c->get_type() Returns the type of control information stored.
