Any workaround to update a file inline without changing the whitespace.

[Bennet-Sunder]

Suppose I have a yml file like below, and I am doing some in place update to the file. The result joins the multiline file into a single one. With some huge file this might create a overhead to clean up even if it's the right thing. Is there a way we can avoid this problem and have only the updated value as the change in the original file. Or any workarounds to reduce this impact of whitespace.
I did read about an existing issue with whitespace from the docs. But wanted to know if there is a way I can avoid it for now.

Not at the moment sorry :( it's done by the underlying yaml parser and I don't have any control of it.

That said - it only affects the readability of the yaml document - the actual content is the same

true the actual content is the same. However in huge yaml document the diff become too much to keep track of.
