.SH NAME
Perl::Critic::Policy::Subroutines::ProhibitManyArgs \- Too many arguments.
.SH AFFILIATION
.IX Header "AFFILIATION"
This Policy is part of the core Perl::Critic
distribution.
.SH DESCRIPTION
.IX Header "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.
.SH CONFIGURATION
.IX Header "CONFIGURATION"
By default, this policy allows up to 5 arguments without warning.  To
change this threshold, put entries in a \fI.perlcriticrc\fR file like
this:
.PP
.Vb 2
\&  [Subroutines::ProhibitManyArgs]
\&  max_arguments = 6
.Ve
.PP
To ignore \f(CW$self\fR or \f(CW$class\fR in your argument count, as long as they're
the first argument, use:
.PP
.Vb 2
\&  [Subroutines::ProhibitManyArgs]
\&  skip_object = 1
.Ve
.SH CAVEATS
.IX Header "CAVEATS"
PPI doesn't currently detect anonymous subroutines, so we don't check
those.  This should just work when PPI gains that feature.
.PP
We don't check for \f(CW@ARG\fR, the alias for \f(CW@_\fR from English.pm.
That's deprecated anyway.
.SH CREDITS
.IX Header "CREDITS"
Initial development of this policy was supported by a grant from the
Perl Foundation.
