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
)
)
