NAME

Perl::Critic::Policy::BuiltinFunctions::RequireBlockGrep - Write "grep { /$pattern/ } @list" instead of "grep /$pattern/, @list".

CONTENTS

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.
