NAME
namespace::autoclean - Keep imports out of your namespace
VERSION
version 0.08
SYNOPSIS
package Foo;
use namespace::autoclean;
use Some::Package qw/imported_function/;
sub bar { imported_function('stuff') }
# later on:
Foo->bar; # works
Foo->imported_function; # will fail. imported_function got cleaned after compilationDESCRIPTION
When you import a function into a Perl package, it will naturally also be available as a method.
The namespace::autoclean pragma will remove all imported symbols at the end of the current package's compile cycle. Functions called in the package itself will still be bound by their name, but they won't show up as methods on your class or instances.
This module is very similar to namespace::clean, except it will clean all imported functions, no matter if you imported them before or after you used the pagma. It will also not touch anything that looks like a method, according to Class::MOP::Class::get_method_list.
If you're writing an exporter and you want to clean up after yourself (and your peers), you can use the -cleanee switch to specify what package to clean:
package My::MooseX::namespace::autoclean;
use strict;
use namespace::autocleanclean (); # no cleanup, just load
sub import {
namespace::autoclean->import(
-cleanee => scalar(caller),
);

PARAMETERS
-also => [ ITEM | REGEX | SUB, .. ]
-also => ITEM
-also => REGEX
-also => SUB
Sometimes you don't want to clean imports only, but also helper functions you're using in your methods. The -also switch can be used to declare a list of functions that should be removed additional to any imports:
use namespace::autoclean -also => ['some_function', 'another_function'];If only one function needs to be additionally cleaned the -also switch also accepts a plain string:
use namespace::autoclean -also => 'some_function';In some situations, you may wish for a more powerful cleaning solution.
The -also switch can take a Regex or a CodeRef to match against local function names to clean.
use namespace::autoclean -also => qr/^_/
use namespace::autoclean -also => sub { $_ =~ m{^_} };
use namespace::autoclean -also => [qr/^_/ , qr/^hidden_/ ];
use namespace::autoclean -also => [sub { $_ =~ m/^_/ or $_ =~ m/^hidden/ }, sub { uc($_) == $_ } ];
