NAME¶

Debian::Control::Stanza - 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 is 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:

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:

looks_like_an_x_field($field)

Returns true if $field is considered appropriate to name a user-defined field.

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.
