NAME¶
Perl::Critic::Policy::BuiltinFunctions::RequireBlockGrep - Write "grep { $_ =~ /$pattern/ } @list" instead of "grep /$pattern/, @list".
AFFILIATION¶
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION¶
The expression forms of "grep" and "map" are awkward and hard to read. Use the block forms instead.
@matches = grep /pattern/, @list; #not ok @matches = grep { /pattern/ } @list; #ok @mapped = map transform($_), @list; #not ok @mapped = map { transform($_) } @list; #ok
CONFIGURATION¶
This Policy is not configurable except for the standard options.
