=head1 NAME
Dpkg::Conf - parse dpkg configuration files
=head1 DESCRIPTION
The Dpkg::Conf object can be used to read options from a configuration
file. It can exports an array that can then be parsed exactly like @ARGV.
=head1 FUNCTIONS
=over 4
=item my $conf = Dpkg::Conf->new(%opts)
Create a new Dpkg::Conf object. Some options can be set through %opts:
if allow_short evaluates to true (it defaults to false), then short
options are allowed in the configuration file, they should be prepended
with a single hyphen.
=cut
sub new {
my ($this, %opts) = @_;
my $class = ref($this) || $this;
my $self = {
options => [],
allow_short => 0,
};
foreach my $opt (keys %opts) {
$self->{$opt} = $opts{$opt};
}
bless $self, $class;
return $self;
}
=item @$conf
=item @options = $conf->get_options()
Returns the list of options that can be parsed like @ARGV.
=cut
sub get_options {
my ($self) = @_;
return @{$self->{options}};
}
=item $conf->load($file)
Read options from a file. Return the number of options parsed.
=item $conf->parse($fh)
Parse options from a file handle. Return the number of options parsed.
=cut
sub parse {
my ($self, $fh, $desc) = @_;

while (<$fh>) {

s/\s+/=/ unless m/=/; # First spaces becomes = if no =

}
}
return $count;
}
=item $conf->filter(remove => $rmfunc)
=item $conf->filter(keep => $keepfunc)
Filter the list of options, either removing or keeping all those that
return true when &$rmfunc($option) or &keepfunc($option) is called.
=cut
sub filter {
my ($self, %opts) = @_;
if (defined($opts{remove})) {
@{$self->{options}} = grep { not &{$opts{remove}}($_) }

}
if (defined($opts{keep})) {
@{$self->{options}} = grep { &{$opts{keep}}($_) }
@{$self->{options}};
}
}
=item $string = $conf->output($fh)
Write the options in the given filehandle (if defined) and return a string
representation of the content (that would be) written.
=item "$conf"
Return a string representation of the content.
=item $conf->save($file)
Save the options in a file.
=cut

my ($self, $fh) = @_;
