.SH "NAME"
Dpkg::Control \- parse and manipulate official control\-like information
.SH "DESCRIPTION"
.IX Header "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.
.PP
The types are constants that are exported by default. Here's the full
list:
.IP "\s-1CTRL_UNKNOWN\s0" 4
.IX Item "CTRL_UNKNOWN"
This type is the default type, it indicates that the type of control
information is not yet known.
.IP "\s-1CTRL_INFO_SRC\s0" 4
.IX Item "CTRL_INFO_SRC"
Corresponds to the first block of information in a debian/control file in
a Debian source package.
.IP "\s-1CTRL_INFO_PKG\s0" 4
.IX Item "CTRL_INFO_PKG"
Corresponds to subsequent blocks of information in a debian/control file
in a Debian source package.
.IP "\s-1CTRL_INDEX_SRC\s0" 4
.IX Item "CTRL_INDEX_SRC"
Corresponds to an entry in a Sources file of a source package
repository.
.IP "\s-1CTRL_INDEX_PKG\s0" 4
.IX Item "CTRL_INDEX_PKG"
Corresponds to an entry in a Packages file of a binary package
repository.
.IP "\s-1CTRL_PKG_SRC\s0" 4
.IX Item "CTRL_PKG_SRC"
Corresponds to a .dsc file of a Debian source package.
.IP "\s-1CTRL_PKG_DEB\s0" 4
.IX Item "CTRL_PKG_DEB"
Corresponds to the control file generated by dpkg-gencontrol
(DEBIAN/control) and to the same file inside .deb packages.
.IP "\s-1CTRL_FILE_CHANGES\s0" 4
.IX Item "CTRL_FILE_CHANGES"
Corresponds to a .changes file.
.IP "\s-1CTRL_FILE_VENDOR\s0" 4
.IX Item "CTRL_FILE_VENDOR"
Corresponds to a vendor file in /etc/dpkg/origins/.
.IP "\s-1CTRL_FILE_STATUS\s0" 4
.IX Item "CTRL_FILE_STATUS"
Corresponds to an entry in dpkg's status file (/var/lib/dpkg/status).
.IP "\s-1CTRL_CHANGELOG\s0" 4
.IX Item "CTRL_CHANGELOG"
Corresponds to the output of dpkg-parsechangelog.
.SH "FUNCTIONS"
.IX Header "FUNCTIONS"
All the methods of Dpkg::Control::Hash are available. Those listed below
are either new or overridden with a different behaviour.
.ie n .IP "my $c = Dpkg::Control\->new(%opts)" 4
.el .IP "my \f(CW$c\fR = Dpkg::Control\->new(%opts)" 4
.IX Item "my $c = Dpkg::Control->new(%opts)"
If the \*(L"type\*(R" option is given, it's used to setup default values
for other options. See \fIset_options()\fR for more details.
.ie n .IP "$c\->set_options(%opts)" 4
.el .IP "\f(CW$c\fR\->set_options(%opts)" 4
.IX Item "$c->set_options(%opts)"
Changes the value of one or more options. If the \*(L"type\*(R" option is changed,
it is used first to define default values for others options. The option
\&\*(L"allow_pgp\*(R" is set to 1 for \s-1CTRL_PKG_SRC\s0 and \s-1CTRL_FILE_CHANGES\s0 and to 0
otherwise. The option \*(L"drop_empty\*(R" is set to 0 for \s-1CTRL_INFO_PKG\s0 and
\&\s-1CTRL_INFO_SRC\s0 and to 1 otherwise. The option \*(L"name\*(R" is set to a textual
description of the type of control information.
.Sp
The output order is also set to match the ordered list returned by
Dpkg::Control::Fields::field_ordered_list($type).
.ie n .IP "$c\->\fIget_type()\fR" 4
.el .IP "\f(CW$c\fR\->\fIget_type()\fR" 4
.IX Item "$c->get_type()"
Returns the type of control information stored. See the type parameter
set during \fInew()\fR.
