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.
