Perl Style: Parallelism

Jan 1, 1998 by Tom Christiansen

• Code legibility is dramatically increased by consistency and parallelism. Compare

      my $filename =    $args{PATHNAME};
      my @names    = @{ $args{FIELDNAMES} };
      my $tab      =    $args{SEPARATOR};
  

  with

      my $filename = $args{PATHNAME};
      my @names = @{$args{FIELDNAMES}};
      my $tab = $args{SEPARATOR};
  

• Line up your # comments or your || die all at one column:

      socket(SERVER, PF_UNIX, SOCK_STREAM, 0) || die "socket $sockname: $!";
      bind  (SERVER, $uaddr)                  || die "bind $sockname: $!";
      listen(SERVER,SOMAXCONN)                || die "listen $sockname: $!";
  

Forward to Embrace && and || for Control and Values
