Perl::Critic::Policy::BuiltinFunctions::ProhibitStringySplit(3)
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.
