Perl::Critic::Policy::Bangs::ProhibitDebuggingModules - Prohibit loading of debugging modules like Data::Dumper |

=head1 DESCRIPTION |
17
|
|
|
|
|
|
|
|
18
|
|
|
|
|
|
|
This policy prohibits loading common debugging modules like L<Data::Dumper>. |
19
|
|
|
|
|
|
|
|
20
|
|
|
|
|
|
|
While such modules are incredibly useful during development and debugging, |
21
|
|
|
|
|
|
|
they should probably not be loaded in production use. If this policy is |
22
|
|
|
|
|
|
|
violated, it probably means you forgot to remove a C<use Data::Dumper;> line |
23
|
|
|
|
|
|
|
that you had added when you were debugging. |

To add more modules that shouldn't be loaded unless you're actively debugging |
38
|
|
|
|

|
something, add them in F<.perlcriticrc> using the C<deubgging_modules> option. |
