YAML Adapter

The built-in YAML adapter uses js-yaml for YAML parsing and serialization.

Usage

from yaml to object
transform
  set name = name
  set age  = age

from object to yaml
transform clone

from yaml to yaml
transform
  set key   = key
  set value = value

Options

Options are forwarded directly to the underlying js-yaml functions.

Parse options (yaml.load)

Option	Type	Description
schema	string	YAML schema to use (default: DEFAULT_SCHEMA)
json	boolean	Allow duplicate keys (last value wins, like JSON)

Serialize options (yaml.dump)

Option	Type	Default	Description
indent	number	2	Number of spaces per indentation level
lineWidth	number	80	Max line width before wrapping (-1 = no limit)
noRefs	boolean	false	Disable YAML anchors/aliases for duplicate objects
sortKeys	boolean	false	Sort object keys alphabetically
flowLevel	number	-1	Level at which to switch to flow style (-1 = block)

Examples

// 4-space indent, no line wrapping
from object to yaml(indent=4, lineWidth=-1)
transform clone

// Parse with duplicate keys allowed
from yaml(json=true) to object
transform clone
