Postfix::Parse::Mailq(3pm) User Contributed Perl Documentation Postfix::Parse::Mailq(3pm)NAME
Postfix::Parse::Mailq - parse the output of the postfix mailq command
VERSION
version 1.001
SYNOPSIS
use Postfix::Parse::Mailq;
my $mailq_output = `mailq`;
my $entries = Postfix::Parse::Mailq->read_string($mailq_output);
my $bytes = 0;
for my $entry (@$entries) {
next unless grep { /@aol.com$/ } @{ $entry->{remaining_rcpts} };
$bytes += $entry->{size};
}
print "$bytes bytes remain to send to AOL destinations
";
WARNING
This code is really rough and the interface will change. Entries will be objects. There will be some more methods. Still, the basics are
likely to keep working, or keep pretty close to what you see here now.
METHODS
read_file
read_handle
read_string
my $entries = Postfix::Parse::Mailq->read_string($string, \%arg);
This methods read the output of postfix's mailq from a file (by name), a filehandle, or a string, respectively. They return an arrayref of
hashrefs, each hashref representing one entry in the queue as reported by mailq.
Valid arguments are:
spool - a hashref of { queue_id -> spool_name } pairs
if given, this will be used to attempt to indicate in which
spool messages currently are; it is not entirely reliable (race!)
parse_block
my $entry = Mailq->parse_block(@lines);
Given all the lines in a single entry's block of lines in mailq output, this returns data about the entry.

CSS - Object oriented access to Cascading Style Sheets (CSS)
SYNOPSIS
use CSS;
# create a CSS object with the default options
my $css = CSS->new();
# create a CSS object with a specific parser
my $css = CSS->new( { 'parser' => 'CSS::Parse::Lite' } );
my $css = CSS->new( { 'parser' => 'CSS::Parse::Heavy' } );
my $css = CSS->new( { 'parser' => 'CSS::Parse::Compiled' } );
# create a CSS object with a specific adaptor
my $css = CSS->new( { 'adaptor' => 'CSS::Adaptor' } );
my $css = CSS->new( { 'adaptor' => 'CSS::Adaptor::Pretty' } );
my $css = CSS->new( { 'adaptor' => 'CSS::Adaptor::Debug' } );
# parse some CSS from a string
$css->read_string( $css_data );
$css->read_string( ( $css_data, $more_css_data ) );
# parse some CSS from a file
$css->read_file( 'my_file.css' );
$css->read_file( ( 'my_file.css', 'my_other_file.css' ) );
# output the CSS using the current adaptor
print $css->output();
# set a new adaptor and then output the CSS
$css->set_adaptor( 'CSS::Adaptor::Foo' );
print $css->output();
# output the CSS using a tempory adaptor
print $css->output( 'CSS::Adaptor::Bar' );
# forget about the CSS we've already parsed
$css->purge();
DESCRIPTION
This module can be used, along with a CSS::Parse::* module, to parse CSS data and represent it as a tree of objects. Using a
CSS::Adaptor::* module, the CSS data tree can then be transformed into other formats.
NOTICE
From version 1.00 of this module onwards, backwards compatibility is broken. This is due to large changes in the way data is parsed and
then represented internally. Version 0.08 is still available on CPAN: http://search.cpan.org/author/IAMCAL/CSS-0.08/
<http://search.cpan.org/author/IAMCAL/CSS-0.08/>
TREE STRUCTURE
The CSS object is the head of the tree. It contains a list of CSS::Style objects which each represent a CSS ruleset. Each of these objects
contains a list of selectors and properties. Each selector is stored as a CSS::Selector object. Each property object is stored as a
CSS::Property object and contains a list of values. These values are stored as CSS::Value objects.
foo, bar {
baz: fop;
woo: yay houpla;
}
The above example would be represented as a single CSS::Style object. That object would then have two CSS::Selector objects representing
'foo' and 'bar'. It would also have two CSS::Property objects representing 'baz' and 'woo'. The 'baz' object then has a single child
CSS::Value object for 'fop', whilst the 'woo' object has two child objects for 'yay' and 'houpla'.
METHODS
CONSTRUCTOR
"new()" or "new( { ..options.. } )"
An optional hash can contain arguments:
parser module to use as the CSS parser
adaptor adaptor to use for output
ACCESSORS
"read_file( $filename )" or "read_file( @filenames )"
Read one or mores files and parse the CSS within them.
"read_string( $scalar )" or "read_string( @strings )"
Read one or more strings and parse the CSS within them.
"output()" or "output( 'CSS::Adaptor::Foo' )"
Return a string representation of the CSS tree, using either the current adaptor or the specified one.
"set_adaptor( 'CSS::Adaptor::Bar' )"
Set the current adaptor for the CSS tree.
"purge()"
Forget all the objects in the CSS tree;
"get_style_by_selector( 'selector_name' )"
Returns the first CSS::Style object with the specified selector name attached. Returns zero on failure.
