Preserve LHS quotes when converting to properties style

[geekosphere-net]

Saw discussion 699 when trying to migrate from v3 to v4 where we used --printMode pv to "flatten" or convert our yaml to a property string, and while it works for most of our files we just ran into a case where we have a value in the YAML that is quoted and we lose the quotes, any idea how to preserve them?

YAML:

one:
  "two.three":
    four: "five"

when we use the suggestion in 699 we get

one.two.three.four=five

but what we would like to see is

one."two.three".four=five

Is that possible? Not all that familiar with jq. Tried looking at using style="double" or --unwrapScalar=false but neither seemed to help.
Thanks in advance

The quotes on that key are part of the yaml formatting style as opposed to the value - so they do not come through when processing the data.

The closest I can get is to wrap all the properties:

yq eval '.. | select((tag == "!!map" or tag == "!!seq") | not) | (path | .[] |= sub("(.*)", "\"${1}\"") | join(".")) + "=" + .' examples/data1.yaml

to get:

"one"."two.three"."four"=five

Not sure if that helps?

Note that this requires v4.9.1 to be able to escape double quotes in a double quoted string.

It may be possible to come up with an expression that only wraps strings with . in their value by counting how many elements in split('.') there are - that expression would start getting pretty hairy though I think

Thanks for that query I don't think I would have ever figured that out, and having more strings/quotes is better than not having them.
As we are using this as part of a CI/CD process I might be able to use awk or something to determine which strings have a . in them and need special attention.

Thanks!
