man Debian::Control::Stanza (3): single stanza of Debian source package control file

SYNOPSIS

package Binary;
use base 'Debian::Control::Stanza';
use constant fields => qw( Package Depends Conflicts );
1;

DESCRIPTION

Debian::Control::Stanza ins the base class for Debian::Control::Stanza::Source and Debian::Control::Stanza::Binary classes.

FIELDS

Stanza fields are to be defined in the class method fields. Typically this can be done like:

    use constant fields => qw( Foo Bar Baz );

Fields that are to contain dependency lists (as per ``is_dependency_list'' method below) are automatically converted to instances of the Debian::Dependencies class.

CONSTRUCTOR

new

new( { field => value, ... } )

Creates a new Debian::Control::Stanza object and optionally initializes it with the supplied data. The object is hashref based and tied to Tie::IxHash.

You may use dashes for initial field names, but these will be converted to underscores:

    my $s = Debian::Control::Stanza::Source( {Build-Depends => "perl"} );
    print $s->Build_Depends;

METHODS

is_dependency_list($field)

Returns true if $field contains a list of dependencies. By default returns true for the following fields:

Build_Depends
Build_Depends_Indep
Build_Conflicts
Build_Conflicts_Indep
Depends
Conflicts
Enhances
Replaces
Breaks
Pre_Depends
Recommends
Suggests

is_comma_separated($field)

Returns true if the given field is to contain a comma-separated list of values. This is used in stringification, when considering where to wrap long lines.

By default the following fields are flagged to contain such lists:

All fields that contain dependencies (see above)
Uploaders
Provides

get($field)

Overrides the default get method from Class::Accessor with Tie::IxHash's FETCH.

set( $field, $value )

Overrides the default set method from Class::Accessor with Tie::IxHash's STORE. In the process, converts $value to an instance of the Debian::Dependencies class if $field is to contain dependency list (as determined by the ``is_dependency_list'' method).

as_string([$width])

Returns a string representation of the object. Ready to be printed into a real debian/control file. Used as a stringification operator.

Fields that are comma-separated use one line per item, except if they are like "${some:Field}", in which case they are wrapped at $widthth column. $width defaults to 80.
