.SH "NAME"
Dpkg::Conf \- parse dpkg configuration files
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The Dpkg::Conf object can be used to read options from a configuration
file. It can export an array that can then be parsed exactly like \f(CW@ARGV\fR.
.SH "METHODS"
.IX Header "METHODS"
.ie n .IP "$conf = Dpkg::Conf\->new(%opts)" 4
.el .IP "\f(CW$conf\fR = Dpkg::Conf\->new(%opts)" 4
.IX Item "$conf = Dpkg::Conf->new(%opts)"
Create a new Dpkg::Conf object. Some options can be set through \f(CW%opts:\fR
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.

Obsolete functions, use \fBget_options()\fR instead. They will croak.
.ie n .IP "$conf\->load($file)" 4
.el .IP "\f(CW$conf\fR\->load($file)" 4
.IX Item "$conf->load($file)"
Read options from a file. Return the number of options parsed.

.ie n .IP "$conf\->load_user_config($file)" 4
.el .IP "\f(CW$conf\fR\->load_user_config($file)" 4
.IX Item "$conf->load_user_config($file)"
Read options from a user configuration file. It will try to use the \s-1XDG\s0
directory, either \f(CW$XDG_CONFIG_HOME\fR/dpkg/ or \f(CW$HOME\fR/.config/dpkg/.
.Sp
Return the number of options parsed.
.ie n .IP "$conf\->load_config($file)" 4

Return the number of options parsed.
.ie n .IP "$conf\->parse($fh)" 4
.el .IP "\f(CW$conf\fR\->parse($fh)" 4
.IX Item "$conf->parse($fh)"
Parse options from a file handle. When called multiple times, the parsed
options are accumulated.
.Sp
Return the number of options parsed.
.ie n .IP "$conf\->filter(%opts)" 4
.el .IP "\f(CW$conf\fR\->filter(%opts)" 4
.IX Item "$conf->filter(%opts)"
Filter the list of options, either removing or keeping all those that
return true when \f(CW$opts\fR{remove}\->($option) or \f(CW$opts\fR{keep}\->($option) is called.
.ie n .IP "$string = $conf\->output([$fh])" 4
.el .IP "\f(CW$string\fR = \f(CW$conf\fR\->output([$fh])" 4
.IX Item "$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.
.ie n .IP """$conf""" 4
.el .IP "``$conf''" 4
.IX Item "$conf"
Return a string representation of the content.
.ie n .IP "$conf\->save($file)" 4
