Starting my own index into the Monastery here, not much by now


Link types at PM (because i tend to forget :-):

  • [id://] a node id
  • [cpan://] searches CPAN
  • [jargon://] searches the Jargon file hosted at the University of Amsterdam.
  • [kobe://] is an alternate for the [cpan://] tag
  • [perldoc://] searches perldoc. The idea here is to provide a way of linking to current Perl documentation.
  • [pad://] is a shortcut to a user's scratch pad

SQL snippets

  • largest grouped sum:
    select key, sum(val) from table group by key order by sum(val) desc read only the first record

perl idioms

  • slurp a file: my $contents = do { local (@ARGV, $/) = $filename; <> };
  • set even elements of @list to 'bla': $_ % 2 or $list[$_] = 'bla' for 0..$#list;
  • getting indices sorted by value: my @indices = sort { $a[$a] <=> $a[$b] } 0..$#a;
  • initialize hash elements: @hash{@array} = (1) x @array
  • assign empty string defaults: $_ = '' for grep ! defined ( $foo, $bar, $baz );
  • blank padding:$str = pack('A40',$str);
