Add object containing double quotes to array

[don-attilio]

Hello,
My starting yaml file is something like:

a:
  b:
    - e1: 'variable1 == "string1"'

I would like to add another element to b and this is what I came up with:

yq e '.a.b + {"e2":"variable2 == '"string2"' | .. style="single"}' myfile.yaml
output:
a:
  b:
    - e1: 'variable1 == "string1"'
    - e2: 'variable2 == string2'

Unfortunately string2 is not surrounded by double quotes.
If I remove from the previous command the single quotes surrounding the double quotes I get this error:

Error: Parsing expression: Lexer error: could not match text starting at 1:50 failing at 1:51.
	unmatched text: "s"

Is there any way to do that?

Thanks,
Attilio

Sorry for the delay, best way I could think of doing it is with an environment variable:

VAL='variable2 == "string2"' ./yq e '.a.b += {"e2": strenv(VAL)} | .. style="single"' data.yaml
