NAME

Perl::Critic::Policy::Modules::ProhibitAutomaticExportation - Export symbols via @EXPORT_OK or %EXPORT_TAGS instead of @EXPORT.

AFFILIATION

This Policy is part of the core Perl::Critic distribution.

DESCRIPTION

When using Exporter, symbols placed in the @EXPORT variable are automatically exported into the caller's namespace. Although convenient, this practice is not polite, and may cause serious problems if the caller declares the same symbols. The best practice is to place your symbols in @EXPORT_OK or %EXPORT_TAGS and let the caller choose exactly which symbols to export.

    package Foo;

    use Exporter 'import';
    our @EXPORT      = qw(foo $bar @baz);                  # not ok
    our @EXPORT_OK   = qw(foo $bar @baz);                  # ok
    our %EXPORT_TAGS = ( all => [ qw(foo $bar @baz) ] );   # ok

CONFIGURATION

This Policy is not configurable except for the standard options.
