Test::Stream::Exporter(3)

NAME
Test::Stream::Exporter - Declarative exporter for Test::Stream and friends.

DEPRECATED
This distribution is deprecated in favor of Test2, Test2::Suite, and Test2::Workflow.

See Test::Stream::Manual::ToTest2 for a conversion guide.

DESCRIPTION
Test::Stream::Exporter is an internal implementation of some key features from Exporter::Declare. This is a much more powerful exporting tool than Exporter. This package is used to easily manage complicated export logic across Test::Stream and friends.

SYNOPSIS
    use Test::Stream::Exporter;

    # Export some named subs from the package
    default_exports qw/foo bar baz/;
    exports qw/fluxx buxx suxx/;

    # Export some anonymous subs under specific names.
    export         some_tool    => sub { ... };
    default_export another_tool => sub { ... };

    # Call this when you are done providing exports in order to cleanup your
    # namespace.
    no Test::Stream::Exporter;

    ...;

CONTROLLING IMPORTS

  IMPORTING SUBS WITH ALTERNATE NAMES
Note: If you import Test::Stream::Exporter functions under alternative names, "no Test::Stream::Exporter;" will not find and remove them like it normally would.

The rename syntax is borrowed from Exporter::Declare, which borrowed it from Sub::Exporter.

    use Some::Exporter an_export => {-as => 'new_name'}, other_export => {-as => 'other_name'};

You can also prefix and/or postfix to the names:

    use Some::Exporter an_export => {-preifx => 'my_', postfix '_tool'};

    # Now use it:
    my_an_export_tool(...);

  IMPORTING ALL SUBS
You can use "-all" to import ALL subs exported by a module.

    use Some::Exporter '-all';

This can be combined with aliasing:

    use Some::Exporter '-all', foo => { -as => 'my_foo' };

In this example "foo" will be imported as 'my_foo', all other subs will be imported with their original names. Order is not important here.

  IMPORTING DEFAULTS PLUS
You can use "-default" to import all default subs, then list others you want to import as well.

    use Some::Exporter '-default', qw/and_this and_that/;

If you want to import all the defaults AND rename one or more:

    use Some::Exporter '-default', foo => { -as => 'my_foo' };

In this example foo() will be imported as my_foo(). All other defaults will also be imported, but with their original names. Order is not important here.

CUSTOMIZING AN IMPORT METHOD
Sometimes you need to make a custom import method, but you still want to use the exporter tool to manage exports. here is how you do it:

    use Test::Stream::Exporter qw/export exports export_from/;
    export foo => sub { 'foo' };
    export qw/bar baz/;

    sub import {
        my $class = shift;
        my @exports = @_;

        # Do whatever you need to
        ...

        # Now go ahead and do the exporting with your list
        my $caller = caller;
        export_from($class, $caller, \@exports);
    }

    # This will cleanup the namespace, including 'export_from', do you need to
    # do it AFTER your import method.
    no Test::Stream::Exporter;

    sub bar { 'bar' }
    sub baz { 'baz' }

    1;

EXPORTS

  DEFAULT
METHODS

$class->import(@list)
    Your class needs this to function as an exporter.

FUNCTIONS

Note: All of thease are removed by default when you run "no Test::Stream::Exporter;"

export NAME => sub { ... }
default_export NAME => sub { ... }
    These are used to define exports that may not actually be subs in the current package.

exports qw/foo bar baz/
default_exports qw/foo bar baz/
    These let you export package subs en mass.

  OTHER AVAILABLE EXPORTS
METHODS

$class->export_to($dest)
$class->export_to($dest, \@symbols)
    Export from the exporter class into the $dest package. The seconond argument is optional, if it is omitted the default export list will be used. The second argument must be an arrayref with export names.

FUNCTIONS

Note: All of thease are removed by default when you run "no Test::Stream::Exporter;"

export_from($from, $to)
export_from($from, $to, \@symbols)
    This will export all the specified symbols from the $from package to the $to package.
