Perl::Critic::Policy::Variables::ProhibitLocalVars(3pm) User Contributed Perl DocumentationPerl::Critic::Policy::Variables::ProhibitLocalVars(3pm)

NAME

       Perl::Critic::Policy::Variables::ProhibitLocalVars - Use "my" instead of "local", except when you have to.

AFFILIATION

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

DESCRIPTION

       Since Perl 5, there are very few reasons to declare "local" variables.  The most common exceptions are Perl's magical global variables.	If
       you do need to modify one of those global variables, you should localize it first.  You should also use the English module to give those
       variables more meaningful names.

	   local $foo;	 #not ok
	   my $foo;	 #ok

	   use English qw(-no_match_vars);
	   local $INPUT_RECORD_SEPARATOR    #ok
	   local $RS			    #ok
	   local $/;			    #not ok

CONFIGURATION

       This Policy is not configurable except for the standard options.

NOTES

       If an external module uses package variables as its interface, then using "local" is actually a pretty sensible thing to do.  So
       Perl::Critic will not complain if you "local"-ize variables with a fully qualified name such as $Some::Package::foo.  However, if you're in
       a position to dictate the module's interface, I strongly suggest using accessor methods instead.
