Perl::Critic::Policy::CodeLayout::RequireTrailingCommas(3) Put a comma at the end of every multi-line list declaration, including the last one.


This Policy is part of the core Perl::Critic distribution.


Conway suggests that all elements in a multi-line list should be separated by commas, including the last element. This makes it a little easier to re-order the list by cutting and pasting.

    my @list = ($foo,
                $baz);  #not ok
    my @list = ($foo,
                $baz,); #ok


This Policy is not configurable except for the standard options.


In the PPI parlance, a ``list'' is almost anything with parentheses. I've tried to make this Policy smart by targeting only ``lists'' that have at least one element and are being assigned to something. However, there may be some edge cases that I haven't covered. If you find one, send me a note.
