test: Single ending newline
|
|
brief: >
|
|
A pipe character, followed by an indented
|
|
block of text is treated as a literal
|
|
block, in which newlines are preserved
|
|
throughout the block, including the final
|
|
newline.

yaml: |
|

Foo

test: The '+' indicator
|

The '+' indicator says to keep newlines at the end of text
|
|
blocks.

test: Three trailing newlines in literals
|
|
brief: >
|
|
To give you more control over how space
|
|
is preserved in text blocks, YAML has
|
|
the keep '+' and chomp '-' indicators.
|
|
The keep indicator will preserve all
|
|
ending newlines, while the chomp indicator
|
|
will strip all ending newlines.
|
|
yaml: |
|
|
clipped: |
|
|
This has one newline.
|
|
|
|
|
|
|
|
same as "clipped" above: "This has one newline.\n"
|
|
|
|
stripped: |-
|
|
This has no newline.
|
|
|
|
|
|
|
|
same as "stripped" above: "This has no newline."
|
|
|
|
kept: |+
|
|
This has four newlines.
|
|
|
|
|
|
|
|
same as "kept" above: "This has four newlines.\n\n\n\n"
|
|
php: |
|
|
array(
|
|
'clipped' => "This has one newline.\n",
|
|
'same as "clipped" above' => "This has one newline.\n",
|
|
'stripped' => 'This has no newline.',

test: Extra trailing newlines with spaces
|
|
todo: true
|
|
brief: >
|
|
Normally, only a single newline is kept
|
|
from the end of a literal block, unless the
|
|
keep '+' character is used in combination
|
|
with the pipe. The following example
|
|
will preserve all ending whitespace
|
|
since the last line of both literal blocks
|
|
contains spaces which extend past the indentation
|
|
level.
|
|
yaml: |
|
|
---
|
|
this: |
|
|
Foo
|
|
|
|
|
|
kept: |+
|
|
Foo
|

test: Folded Block in a Sequence
|
|
brief: >
|
|
A greater-then character, followed by an indented
|
|
block of text is treated as a folded block, in
|
|
which lines of text separated by a single newline
|
|
are concatenated as a single line.
|
|
yaml: |
|
|
---
|
|
- apple
|
|
- banana

|

|

the beauty of yaml?

test: Folded Block as a Mapping Value

|
brief: >
|

Both literal and folded blocks can be
|
|
used in collections, as values in a
|
|
sequence or a mapping.
