Sub::Exporter::Tutorial is a friendly guide to exporting with Sub::Exporter.

Whats an Exporter?

When you use a module, first it is required, then its import method is called. The Perl documentation tells us that the following two lines are equivalent:

use Module LIST;

BEGIN { require Module; Module->import(LIST); }

The import method is the modules exporter.

The Basics of Sub::Exporter

Sub::Exporter builds a custom exporter which can then be installed into your module. It builds this method based on configuration passed to its setup_exporter method.

A very basic use case might look like this:

package Addition;
use Sub::Exporter;
Sub::Exporter::setup_exporter({ exports => [ qw(plus) ]});

sub plus { my ($x, $y) = @_; return $x + $y; }

This would mean that when someone used your Addition module, they could have its plus routine imported into their package:

use Addition qw(plus);

my $z = plus(2, 2); # this works, because now plus is in the main package

That syntax to set up the exporter, above, is a little verbose, so for the simple case of just naming some exports, you can write this:

use Sub::Exporter -setup => { exports => [ qw(plus) ] };
...which is the same as the original example -- except that now the exporter is built and installed at compile time. Well, that and you typed less.

Using Export Groups

You can specify whole groups of things that should be exportable together. These are called groups. Exporter calls these tags. To specify groups, you just pass a groups key in your exporter configuration:

package Food;
use Sub::Exporter -setup => {
exports => [ qw(apple banana beef fluff lox rabbit) ],
groups => {
fauna => [ qw(beef lox rabbit) ],
flora => [ qw(apple banana) ],
}
};

Now, to import all that delicious foreign meat, your consumer needs only to write:

use Food qw(:fauna);
use Food qw(-fauna);

Either one of the above is acceptable. A colon is more traditional, but barewords with a leading colon cant be enquoted by a fat arrow. Well see why that matters later on.

Groups can contain other groups. If you include a group name (with the leading dash or colon) in a group definition, it will be expanded recursively when the exporter is called. The exporter will not recurse into the same group twice while expanding groups.

There are two special groups: all and default. The all group is defined by default, and contains all exportable subs. You can redefine it, if you want to export only a subset when all exports are requested. The default group is the set of routines to export when nothing specific is requested. By default, there is no default group.

Everything we do online, what we browse, what feeds we read, what we search for, increasingly represents who we are. This "Attention Data" has real value and needs to be protected.

Until now, only companies on the other side of our clicking captured this value. AttentionTrust is a not-for-profit organization that attempts to place the user in control of his or her Attention data.

Attention Recorder is a Firefox extension that allows users to monitor their clickstream and browsing history. YOU alone are in sole control of this information, when it is stored locally on your desktop in an XML file. YOU alone can choose to share it with a service you trust.

AttentionTrust believes that you have the following rights to your Attention Data:

1. Property--You own your data
2. Mobility--You can copy or delete your data.
3. Economy--You can exchange your data with others your trust.
4. Transparency--You can see how your data is being used

Array::Each::Tutorial - POD giving various examples how to use Array::Each.

SYNOPSIS

man Array::Each
man Array::Each::Tutorial

or

perldoc Array::Each
perldoc Array::Each::Tutorial

Overview

This tutorial contains only POD, so dont do this:

use Array::Each::Tutorial; # dont do this

Rather, simply read the POD (as you are doing). But first, please read the docs for Array::Each, because the whole scoop is there.

This tutorial is intended to augment those docs with examples showing situations where you might want to use Array::Each instead of other techniques.

EXAMPLES

Parallel Arrays vs. Using a Hash

First of all, use a hash. Its almost always the best solution if you want to associate a "key" with a "value". And there are modules available that will let you do wonderful things with hashes, like keeping the keys sorted or keeping them in the order they were added.

So given a hash, you might at some point want to do this:

my %h = ( a=>1, b=>2, c=>3, d=>4, e=>5 );
while( my( $k, $v ) = each %h ) {
# ... do something with $k and $v ...
}

On the other hand, if parallel arrays better implement your algorithm, then you may find you want to do something like this:

my @k = qw( a b c d e );
my @v = qw( 1 2 3 4 5 );
for my $i ( 0 .. $#k ) {
my( $k, $v ) = ( $k[$i], $v[$i] );
# ... do something with $k and $v (and maybe $i) ...
}

Using Array::Each, you could do the same thing this way:

use Array::Each;
my @k = qw( a b c d e );
my @v = qw( 1 2 3 4 5 );
my $obj = Array::Each->new( @k, @v );
while( my( $k, $v, $i ) = $obj->each ) {
# ... do something with $k and $v (and maybe $i) ...
}

If you dont need $i at all, you can leave it out, e.g.,

while( my( $k, $v ) = $obj->each ) {
# ... do something with $k and $v ...
}

If you have more than two parallel arrays, include them all in the call to new() and add as many "capture" variables as you need, e.g.,

my @k = qw( a b c d e );
my @v = qw( 1 2 3 4 5 );
my @p = qw( - + ~ = : );
my $obj = Array::Each->new( @k, @v, @p );
while( my( $k, $v, $p, $i ) = $obj->each ) {
# ... do something with $k, $v, and $p (and maybe $i) ...
}

Privateer Gemini Gold is a remake of Wing Commander Privateer.
Back in 1993 Privateer was released as part of the Wing Commander series and became a great success in the gaming industry. Over 10 years later a small group of privateer enthusiasts reintroduce the game with a new graphic engine and real 3d spaceflight.
As Grayson Burrows you inherited a small old scout class ship from your grandfather, to start over as a Privateer in a new and sparsely populated sector of the Confederation. Take your chance and become a pirate, merchant or hunter upgrade your ship and experience the hard truth in a border sector where noone has anything to give away...
This project is different from Privateer Remake in that it focuses on recreating the original Privateer without additional fan created content, it however shares the source with Privateer Remake.
Enhancements:
- new paradigm model with turrets
- new "New Constantinople Superbase" model
Bugfixes:

JOpt.SDK library is a routing software for Java that uses specialized genetic algorithms to calculate an optimized allocation of orders and stops to mobile resources.
The algorithm not only provides tours at minimum costs but also considers an arbitrary set of constraints for each tour. You may define your own constraints and optimization goals in order to customize JOpt.SDK to your specific planning needs or you decide to use one of our best practices addons in order to achieve a fast application of our optimization algorithms to selected industries.
JOpt.SDK can solve nearly any problem that can be classified by one of the following types:
TSP - Traveling Salesman Problem. JOpt.SDK finds the shortest or fastest path for your mobile resources
VRPTW - Vehicle routing problem with time windows - like TSP but for a set of vehicles. JOpt.SDK finds an optimal allocation of orders and stops within a vehicle fleet. It may also consider different constraints for vehicles, drivers and stops.
JOpt.SDK functionality can be accessed via Java API and thus fits seamlessly into any JAVA application. Software developers may integrate the JOpt.SDK component into their application in order to offer their customers a consistent solution including optimization of mobile workforce schedules.
Enhancements:
- The tutorial has been revised to reflect some major API changes introduced since JOpt 2.0.0.

Test::LectroTest::Tutorial is a Perl module that contains documentation on how to use LectroTest to test your software.

SYNOPSIS

LectroTest is an automated, specification-based testing system. To use it, declare properties that specify the expected behavior of your software. Then invoke LectroTest to test whether those properties hold.

LectroTest does this by running repeated random trials against your software. If LectroTest finds that a property doesnt hold, it emits the counterexample that "broke" your software. You can then plug the counterexample into your software to debug the problem. (Its also a good idea to add the counterexample to your list of regression tests.)

Think of your softwares behavior as a haystack that youre searching for needles. Each error is a needle. You want to find the needles and remove of them. LectroTest will search the haystack for you -- its nice that way -- but first you must tell it about the shape of the haystack and how to recognize a needle when it sees one.

The Haystack

The shape of the haystack is defined by a set of "generator bindings," in which variables are bound to the output of value generators:

x = 0;

The above asserts for each point in the haystack that the output of the function the_thing_we_are_testing must be non-negative.

Put them together to make a Property

The generator bindings and needle recognizer are combined to make a property:

Property {
##[ x = 0;
}, name => "the_thing_we_are_testing(...) is non-negative";

Youll note that we also added a meaningful name. Although not strictly required, its an excellent practice that makes life easier. (Youll also note that we placed the generator bindings inside of the magic delimiters ##[ ]##. This tells Perl that our bindings are bindings and not regular Perl code.)

We can read the above property like so: "For all integers x and all characters c in the range A through Z, we assert that the_thing_we_are_testing is non-negative."

Testing whether your Properties hold

After you define properties for your software, just add them to a small Perl program that uses the Test::LectroTest module:

# MyProperties.l.t

use MyModule; # provides the_thing_we_are_testing
use Test::LectroTest;

Property {
##[ x = 0;
}, name => "the_thing_we_are_testing(...) is non-negative";

Then you can test your properties simply by running the program:

$ perl MyProperties.l.t

If your properties check out, youll see something like this:

1..1
ok 1 - the_thing_we_are_testing(...) is non-negative (1000 attempts)

If something goes wrong, however, LectroTest will tell you where it happened:

1..1
not ok 1 - the_thing_we_are_testing(...) is non-negative
falsified in 23 attempts
# Counterexample:
# $x = 4
# $c = "R"

What this says is that at the point (x=4, c="R") in the haystack, there is a needle (i.e., your property doesnt hold). With this information, you can examine your code to determine the cause of the error.
