Perl::Critic::Policy::BuiltinFunctions::RequireBlockMap

NAME

Perl::Critic::Policy::BuiltinFunctions::RequireBlockMap − Write "map { $_ =~ /$pattern/ } @list" instead of "map /$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.
