in thread YAML newbie help

Indeed, answering my own question after reading more of the long, but well-written specification: a more concise, but equivalent version, is of course: 
 -
  date: 2005-06-01
  team: [ Jack, Jill, Joe ]
  boss: Clara
 -
  date: 2005-06-02
  team: [ Harry, Hillary, Howie ]
  boss: Victoria

Even more concise, each day can be made to fit on one line: 
 - { date: 2005-06-01,  team: [ Harry, Hillary, Howie ],  boss: Clara 
+   }
 - { date: 2005-06-02,  team: [ Jack,  Jill,    Joe   ],  boss: Victor
+ia }

which makes it more readable as a table.

I wonder if you can simplify even further, by factoring out the hash keys? Something on the order of: 

# INCORRECT YAML SYNTAX
 - { date:,      team:,                     boss:    }
 - { 2005-06-01, [ Harry, Hillary, Howie ], Clara    }
 - { 2005-06-02, [ Jack,  Jill,    Joe   ], Victoria }

Probably not.

    I see. I always start with `perldoc YAML', so I would've approached the problem the same way grinder would, akin to 
    use YAML;

my( @foo ) = ({
    'date' => '2005-06-01',
    'boss' => 'Clara',
    'team' => [
      'Jack',
      'Jill',
      'Joe'
    ]
  },
  {
    'date' => '2005-06-02',
    'boss' => 'Victoria',
    'team' => [
      'Harry',
      'Hillary',
      'Howie'
    ]
  }
);
local $YAML::Indent = 4;
local $YAML::UseFold = 1;
print Dump( \@foo );
__END__

    Too bad there isn't an option yet to compress sequences.

    I run a Win32 PPM repository for perl 5.6.x and 5.8.x -- I take requests (README).

      That's what I did too, but the synopsis actually starts with YAML, not with Perl structures.

      grinder and your technique is great for those who are good at thinking in, and writing, Perl data structures. I must shamefully confess that, despite long experience programming Perl, I have trouble distinguishing braces from brackets from curlies, and remembering which does what. So I thought to myself: "Hey, YAML, human-readable! Maybe it can save me from wearing out my AltGr key! (on French keyboard)". But YAML turned out not to be as DWIM as I expected, which isn't surprising. Hence the need for lots of examples for lazy newbies like me.

      Maybe as penance (and when I have time, this was all supposed to be a timesaver...) I'll write up a translation of perldsc into YAML.

        Excellent idea, go for it! I don't recall seeing Manual Guilt work so well before :D Just scan for Declaration of and YAML::Dump() it, shouldn't take long at all
