perl::critic::policy::regularexpressions::prohibitunusedcapture
Perl::Critic::Policy::RegularExpressions::ProhibitUnusedUseruContributed Perl Perl::Critic::Policy::RegularExpressions::ProhibitUnusedCapture(3pm)
NAME
Perl::Critic::Policy::RegularExpressions::ProhibitUnusedCapture - Only use a capturing group if you plan to use the captured value.
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
Perl regular expressions have multiple types of grouping syntax. The basic parentheses (e.g. "m/(foo)/") captures into the magic variable
$1. Non-capturing groups (e.g. "m/(?:foo)/" are useful because they have better runtime performance and do not copy strings to the magic
global capture variables.
It's also easier on the maintenance programmer if you consistently use capturing vs. non-capturing groups, because that programmer can tell
more easily which regexps can be refactored without breaking surrounding code which may use the captured values.
CONFIGURATION
This Policy is not configurable except for the standard options.
CAVEATS
"qr//" interpolation
This policy can be confused by interpolation of "qr//" elements, but those are always false negatives. For example:
my $foo_re = qr/(foo)/;
my ($foo) = m/$foo_re (bar)/x;
A human can tell that this should be a violation because there are two captures but only the first capture is used, not the second. The
policy only notices that there is one capture in the regexp and remains happy.
"@-", "@+", $LAST_MATCH_START and $LAST_MATCH_END
This policy will only recognize capture groups referred to by these variables if the use is subscripted by a literal integer.
$^N and $LAST_SUBMATCH_RESULT
This policy will not recognize capture groups referred to only by these variables, because there is in general no way by static analysis to
determine which capture group is referred to. For example,
m/ (?: (A[[:alpha:]]+) | (Nd+) ) (?{$foo=$^N}) /smx
makes use of the first capture group if it matches, or the second capture group if the first does not match but the second does.
CREDITS
Initial development of this policy was supported by a grant from the Perl Foundation.
