Dpkg::Control::Info(3)						   libdpkg-perl 					    Dpkg::Control::Info(3)

NAME

       Dpkg::Control::Info - parse files like debian/control

DESCRIPTION

       It provides an object to access data of files that follow the same syntax than debian/control.

FUNCTIONS

       $c = Dpkg::Control::Info->new($file)
	   Create a new Dpkg::Control::Info object for $file. If $file is omitted, it loads debian/control. If file is "-", it parses the standard
	   input.

       $c->reset()
	   Resets what got read.

       $c->load($file)
	   Load the content of $file. Exits in case of errors. If file is "-", it loads from the standard input.

       $c->parse($fh, $description)
	   Parse a control file from the given filehandle. Exits in case of errors.  $description is used to describe the filehandle, ideally it's
	   a filename or a description of where the data comes from. It's used in error messages.

       $c->[0]
       $c->get_source()
	   Returns a Dpkg::Control object containing the fields concerning the source package.

       $c->get_pkg_by_idx($idx)
	   Returns a Dpkg::Control object containing the fields concerning the binary package numbered $idx (starting at 1).

       $c->get_pkg_by_name($name)
	   Returns a Dpkg::Control object containing the fields concerning the binary package named $name.

       $c->get_packages()
	   Returns a list containing the Dpkg::Control objects for all binary packages.

       $c->output($filehandle)
	   Dump the content into a filehandle.

       "$c"
	   Return a string representation of the content.

       @{$c}
	   Return a list of Dpkg::Control objects, the first one is corresponding to source information and the following ones are the binary
	   packages information.
