--- %YAML:1.0
test: Simple Sequence
brief: |
    You can specify a list in YAML by placing each
    member of the list on a new line with an opening
    dash. These lists are called sequences.
yaml: |
    - apple
    - banana
    - carrot
php: |
    array('apple', 'banana', 'carrot')
---
test: Sequence With Item Being Null In The Middle
brief: |
    You can specify a list in YAML by placing each
    member of the list on a new line with an opening
    dash. These lists are called sequences.
yaml: |
    - apple
    -
    - carrot
php: |
    array('apple', null, 'carrot')
---
test: Sequence With Last Item Being Null
brief: |
    You can specify a list in YAML by placing each
    member of the list on a new line with an opening
    dash. These lists are called sequences.
yaml: |
    - apple
    - banana
    -
php: |
    array('apple', 'banana', null)
---
test: Nested Sequences
brief: |
    You can include a sequence within another
    sequence by giving the sequence an empty
    dash, followed by an indented list.
yaml: |
    -
     - foo
     - bar
     - baz
php: |
    array(array('foo', 'bar', 'baz'))
---
test: Mixed Sequences
brief: |
    Sequences can contain any YAML data,
    including strings and other sequences.
yaml: |
    - apple
    -
     - foo
     - bar
     - x123
    - banana
    - carrot
php: |
    array('apple', array('foo', 'bar', 'x123'), 'banana', 'carrot')
---
test: Deeply Nested Sequences
brief: |
    Sequences can be nested even deeper, with each
    level of indentation representing a level of
    depth.
yaml: |
    -
     -
      - uno
      - dos
php: |
    array(array(array('uno', 'dos')))
---
test: Simple Mapping
brief: |
    You can add a keyed list (also known as a dictionary or
    hash) to your document by placing each member of the
    list on a new line, with a colon separating the key
    from its value.  In YAML, this type of list is called
    a mapping.
yaml: |
    foo: whatever
    bar: stuff
php: |
    array('foo' => 'whatever', 'bar' => 'stuff')
---
test: Sequence in a Mapping
brief: |
    A value in a mapping can be a sequence.
yaml: |
    foo: whatever
    bar:
     - uno
     - dos
php: |
    array('foo' => 'whatever', 'bar' => array('uno', 'dos'))
---
test: Nested Mappings
brief: |
    A value in a mapping can be another mapping.
yaml: |
    foo: whatever
    bar:
     fruit: apple
     name: steve
     sport: baseball
php: |
    array(
      'foo' => 'whatever',
      'bar' => array(
         'fruit' => 'apple',
         'name' => 'steve',
         'sport' => 'baseball'
       )
    )
---
test: Mixed Mapping
brief: |
    A mapping can contain any assortment
    of mappings and sequences as values.
yaml: |
    foo: whatever
    bar:
     -
       fruit: apple
       name: steve
       sport: baseball
     - more
     -
       python: rocks
       perl: papers
       ruby: scissorses
php: |
    array(
      'foo' => 'whatever',
      'bar' => array(
        array(
            'fruit' => 'apple',
            'name' => 'steve',
            'sport' => 'baseball'
        ),
        'more',
        array(
            'python' => 'rocks',
            'perl' => 'papers',
            'ruby' => 'scissorses'
        )
      )
    )
---
test: Mapping-in-Sequence Shortcut
todo: true
brief: |
     If you are adding a mapping to a sequence, you
     can place the mapping on the same line as the
     dash as a shortcut.
yaml: |
     - work on YAML.py:
        - work on Store
php: |
    array(array('work on YAML.py' => array('work on Store')))
---
test: Sequence-in-Mapping Shortcut
todo: true
brief: |
     The dash in a sequence counts as indentation, so
     you can add a sequence inside of a mapping without
     needing spaces as indentation.
yaml: |
     allow:
     - 'localhost'
     - '%.sourceforge.net'
     - '%.freepan.org'
php: |
     array('allow' => array('localhost', '%.sourceforge.net', '%.freepan.org'))
---
todo: true
test: Merge key
brief: |
     A merge key ('<<') can be used in a mapping to insert other mappings.  If
     the value associated with the merge key is a mapping, each of its key/value
     pairs is inserted into the current mapping.
yaml: |
     mapping:
       name: Joe
       job: Accountant
       <<:
         age: 38
php: |
     array(
       'mapping' =>
       array(
         'name' => 'Joe',
         'job' => 'Accountant',
         'age' => 38
       )
     )
