Dpkg::Control(3perl)

NAME
Dpkg::Control - parse and manipulate official control-like information

DESCRIPTION
The Dpkg::Control object is a smart version of 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:

CTRL_UNKNOWN
    This type is the default type, it indicates that the type of control information is not yet known.

CTRL_TMPL_SRC
    Corresponds to the first source package stanza in a debian/control file in a Debian source package.

CTRL_TMPL_PKG
    Corresponds to subsequent binary package stanza in a debian/control file in a Debian source package.

CTRL_REPO_RELEASE
    Corresponds to a Release file in a repository.

CTRL_REPO_SRC
    Corresponds to a stanza in a Sources file of a source package repository.

CTRL_REPO_PKG
    Corresponds to a stanza in a Packages file of a binary package repository.

CTRL_DSC

CTRL_DEB
    Corresponds to the control file generated by dpkg-gencontrol (DEBIAN/control) and to the same file inside .deb packages.

CTRL_FILE_BUILDINFO
    Corresponds to a .buildinfo file.

CTRL_FILE_CHANGES
    Corresponds to a .changes file.

CTRL_FILE_VENDOR
    Corresponds to a vendor file in $Dpkg::CONFDIR/origins/.

METHODS
All the methods of Dpkg::Control::Hash are available. Those listed below are either new or overridden with a different behavior.

$c = Dpkg::Control->new(%opts)
    Create a new deb822 control object.

    Options:

    type
        Set the deb822 control type, used to setup default values for other options.

    See set_options() for more details.

$c->set_options(%opts)
    Changes the value of one or more options.

    Options:

    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).

    name
        Sets a textual description of the type of control information.

    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.

    allow_duplicate
        Sets whether the parser allows duplicate fields in deb822 control information.

    keep_duplicate
        Sets whether the parser will keep values for duplicate fields found in deb822 control information (when allow_duplicate is enabled), as array references.

    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.

$c->get_type()
    Returns the type of control information stored. See the type parameter set during new().
