jq retain missing array objects from capturing group and update array

Question

Input

[{
        \"tags\": [{
                \"value\": \"domain:sourcing\"
            },
            {
                  


        

Answer 1

Here's another approach. This assumes your tags array will only contain the names you expect.

map(
    reduce (.tags[].value | split(":")) as [$k,$v] (
        {domain:"-",apiname:"-"};
        .[$k] = $v
    )
)

For a more general solution that doesn't assume fixed names and just flattens the tags, I'd do this:

map(
    reduce (.tags[].value | split(":")) as [$k,$v] (
        del(.tags);
        .[$k] = $v
    )
)

Then as you access the fields, just use the alternative operator to set the default value.

(.domain // "-") as $domain
