ex::lib(now lib::abs)

(thanks to A. Shrub ;)

use lib::abs (ex::lib)

use lib::abs '../lib';

use lib::abs '../../*/lib';

use, use, use?

use utf8;use strict;use warnings;use Carp;use Data::Dumper;use open qw(:utf8 :std);use mro 'c3';use feature qw(say state switch);

use warnings?

Use of uninitialized value...

common::sense?

- No utf8 until v3.0
- No open :utf8 support for v3.0+
- No require perl 5.10+ for features
- No Carp
- No mro

use uni::perl ':dumper';

use strict;use feature qw(say state switch);no warnings;use warnings qw(FATAL ...);no warnings qw(exec newline);use utf8;use open (:utf8 :std);use mro 'c3';use autouse 'Carp';use autouse 'Data::Dumper';

Secret feature ;) (pluggable)

Fun syntax

- lvalue- self::init- accessors-fast- constant-def

lvalue

sub mysub : lvalue {get {return 'result for get';}set {my $set_value = shift; # ...}}

self::init

use self::init\-a => qw(a b),\-b => (),\-c => qw( c c ),;

vs

__PACKAGE__->a(qw(a b));__PACKAGE__->b();__PACKAGE__->c(qw(c c));

accessors::fast

use accessors::fast
qw(field1 field2);

vs

use base 'Class::Accessors::Fast';__PACKAGE__->mk_accessors(qw(field1 field2));

constant::def

use constant::abs 'My::DEBUG' => 1;use constant::defDEBUG => 0;

vs

BEGIN { *My::DEBUG = sub () { 1 }; }BEGIN {defined &DEBUG or*DEBUG = sub () { 0 };}

Daemond (github)

- Correct daemonization-Detach- redirection of output- keeping the fileno for STD* handles- chroot- change user- Pluggable engine- Built-in CLI (Command-line interface)- Pidfile- Scoreboard- Different packages for child and parent- Child monitoring for parent death- Timers for termination

Simple Daemond

package SampleD;

use Daemond -parent;name 'test';cli; # Command line controlproc; # Alter $0children 1; # How many childrenpid '/var/run/test.pid';

child {$SIG{USR2} = sub { exit; };while() {do_job();}};

Daemond CLI

Usage: [options] [start|stop|restart|check]Options:-v, --verboseincrease verbosity level-f, --nodetachrun in nodetach mode-c N, --children Nredefine count of children
