perl::critic::policy::builtinfunctions::prohibitstringysplit

Perl::Critic::Policy::BuiltinFunctions::ProhibitStringySUser(Contributed Perl DocPerl::Critic::Policy::BuiltinFunctions::ProhibitStringySplit(3pm)

NAME

       Perl::Critic::Policy::BuiltinFunctions::ProhibitStringySplit - Write "split /-/, $string" instead of "split '-', $string".

AFFILIATION

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

DESCRIPTION

       The "split" function always interprets the PATTERN argument as a regular expression, even if you specify it as a string.  This causes much
       confusion if the string contains regex metacharacters.  So for clarity, always express the PATTERN argument as a regex.

	   $string = 'Fred|Barney';
	   @names = split '|', $string; #not ok, is ('F', 'r', 'e', 'd', '|', 'B', 'a' ...)
	   @names = split m/[|]/, $string; #ok, is ('Fred', Barney')

       When the PATTERN is a single space the "split" function has special behavior, so Perl::Critic forgives that usage.  See "perldoc -f split"
       for more information.

CONFIGURATION

       This Policy is not configurable except for the standard options.
