Perl::Critic::Policy::Subroutines::ProhibitManyArgs.3pm

NAME

Perl::Critic::Policy::Subroutines::ProhibitManyArgs - Too many arguments.

AFFILIATION

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

DESCRIPTION

Subroutines that expect large numbers of arguments are hard to use because programmers routinely have to look at documentation to remember the order of those arguments. Many arguments is often a sign that a subroutine should be refactored or that an object should be passed to the routine.

CONFIGURATION

By default, this policy allows up to 5 arguments without warning. To change this threshold, put entries in a .perlcriticrc file like this:

   [Subroutines::ProhibitManyArgs]
   max_arguments = 6
 
 

CAVEATS

PPI doesn't currently detect anonymous subroutines, so we don't check those. This should just work when PPI gains that feature.

We don't check for @ARG, the alias for @_ from English.pm. That's deprecated anyway.

TO DO

Don't include $self and $class in the count.

CREDITS

Initial development of this policy was supported by a grant from the Perl Foundation.
