Perl::Critic::Policy::BuiltinFunctions::ProhibitStringySplit - Write
$string instead of
This Policy is part of the core Perl::Critic distribution.
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.
This Policy is not configurable except for the standard options.
