Preserve quote style while changing a YAML file #671
Description
I have Rails I18n en.yml file which contains values with or without qoutes.
I want to change this file programmatically, but if I use Psych#load and Psych#dump approach it removes all the quotes from values. I don't want to change styling of existing values, how can I do that?
As I understand parsing the ast is the way, but I want to preserve simplicity of working with YAML as the hash and then simply dump it back as the original file but with a few new key/values.
Input:
en:
account:
invoices:
empty: 'It''s empty here'
tabs:
donations: Donations
giftcards: 'Gift Cards'
membership: Membership
purchases: Purchases
subscription: Subscription
title: 'Invoices History'
Expected result (all styling preserved, new key added):
en:
account:
invoices:
empty: 'It''s empty here'
tabs:
donations: Donations
giftcards: 'Gift Cards'
membership: Membership
purchases: Purchases
subscription: Subscription
my_new_key: New Value
title: 'Invoices History'
