NAME
relative - Load modules with relative names
VERSION
Version 0.04
SYNOPSIS
package BigApp::Report;
use relative qw(Create Publish);
# loads BigApp::Report::Create, BigApp::Report::Publish
use relative qw(..::Utils);
# loads BigApp::Utils
use relative -to => "Enterprise::Framework" => qw(Base Factory);
# loads Enterprise::Framework::Base, Enterprise::Framework::Factory
DESCRIPTION
This module allows you to load modules using only parts of their name, relatively to the current module or to a given module. Module names
are by default searched below the current module, but can be searched upper in the hierarchy using the "..::" syntax.
In order to further loosen the namespace coupling, "import" returns the full names of the loaded modules, making object-oriented code
easier to write:
use relative;
my ($Maker, $Publisher) = import relative qw(Create Publish);
my $report = $Maker->new;
my $publisher = $Publisher->new;
my ($Base, $Factory) = import relative -to => "Enterprise::Framework"
=> qw(Base Factory);
my $thing = $Factory->new;
This can also be written using aliases:
use relative -aliased => qw(Create Publish);
my $report = Create->new;
my $publisher = Publisher->new;
use relative -to => "Enterprise::Framework", -aliased => qw(Base Factory);
my $thing = Factory->new;
IMPORT OPTIONS
Import options can be given as an hashref or an arrayref as the first argument:
# options as a hashref
import relative { param => value, ... }, qw(Name ...);
# options as an arrayref
import relative [ param => value, ... ], qw(Name ...);
In order to simplyfing syntax, options can also be given as dash-prefixed params:
import relative -param => value, qw(name ...);
Available options:
o "to" can be used to indicate another hierarchy to search modules inside.
Examples
# in a hashref:
import relative { to => "Some::Other::Namespace" }, qw(Other Modules);
# as dash-param:
import relative -to => "Some::Other::Namespace", qw(Other Modules);
o "aliased" will create constants, named with the last component of each loaded module, returning its corresponding full name. Yes, this
feature is very similar to what "aliased" does as it was added per Ovid request ":-)"
Examples
# in a hashref:
import relative { aliased => 1 }, qw(Whack Zlonk);
my $frob = Whack->fizzle;
# as dash-param:
import relative -aliased, qw(Whack Zlonk);
my $frob = Whack->fizzle;
"import" will "die" as soon as a module can't be loaded.
"import" returns the full names of the loaded modules when called in list context, or the last one when called in scalar context.
