New submission from Harshini <[email protected]>:
I observed that the indentation is not preserved when I load and dump a YAML
file using round_trip_dump from ruamel.yaml. For example, I have an input file
with the data:
Inventory:
- name: Apples
count: 10
vendors:
- - vendor_name: xyz
boxes: 2
- name: Bananas
number: 20
vendors:
- - vendor_name: abc
boxes: 1
- vendor_name: xyz
boxes: 4
I wrote a simple script that just loads and dumps the same data into a new YAML
file:
import sys
import os
import ruamel.yaml
yaml = ruamel.yaml.YAML()
input_file = sys.argv[1]
output_yaml = r"data_output.yaml"
output = open(output_yaml, 'w+')
with open(input_file, 'r') as f:
data = yaml.load(f)
ruamel.yaml.round_trip_dump(data, output)
I would expect the output yaml to be the same as the input yaml but what is see
is:
Inventory:
- name: Apples
count: 10
vendors:
- - vendor_name: xyz
boxes: 2
- name: Bananas
number: 20
vendors:
- - vendor_name: abc
boxes: 1
- vendor_name: xyz
boxes: 4
It is missing the indentation under Inventory as there should be a tab before
"- name" .
