So I have two yaml files A and B and I want the contents of A to be inserted inside B, either spliced into the existing data structure (eg. an array), or as a child of an element, eg. the value for a certain hash key.
Is this possible at all? How? If not, any pointers to a normative reference?
You could treat file A as a string inside file B. Here's an example inspired by a comment on another question that uses YAML's literal style for strings:
B.yaml: |
- heading:
name: A name
taco: Yes
age: 32
- heading:
name: Another name
taco: No
age: 27
When loaded, you'll get a mapping from "B.yaml" to the text of file B. Just load this resulting text to get the data in the second file out.
Here's how it looks in Python, using PyYAML:
from pprint import pprint
import yaml
fileA = """
fileB: |
- heading:
name: A name
taco: Yes
age: 32
- heading:
name: Another name
taco: No
age: 27
"""
dataA = yaml.load(fileA)
dataB = yaml.load(dataA["fileB"])
pprint(dataA) # A mapping to the text of the inner file
pprint(dataB) # The data from that inner file
