Building objects with jq - json

Question

Using jq I'd like to convert data of the format:
{
"key": "something-else",
"value": {
"value": "bloop",
"isEncrypted": false
}
}
{
"key": "something",
"value": {
"value": "blah",
"isEncrypted": false
}
}
To the format:
{
something: "blah",
something-else: "bloop"
}
Filtering out 'encrypted values' along the way. How can I achieve this? I've gotten as far as the following:
.parameters | to_entries[] | select (.value.isEncrypted == false) | .key + ": " + .value.value
Which produces:
"something-else: bloop"
"something: blah"
Close, but not there just yet. I suspect that there's some clever function for this.

Answer 1

Given the example input, here's a simple solution, assuming the stream of objects is available as an array. (This can be done using jq -s if the JSON objects are given as input to jq, or in your case, following your example, simply using .parameters | to_entries).
map( select(.value.isEncrypted == false) | {(.key): .value.value } )
| add
This produces the JSON object:
{
"something-else": "bloop",
"something": "blah"
}
The key ideas here are:
the syntax for object construction: {( KEYNAME ): VALUE}
add
One way to gain an understanding of how this works is to run the first part of the filter (map(...)) first.
Using keys_unsorted
If you want to avoid the overhead of to_entries, you might want to consider the following approach, which piggy-backs off your implicit description of .parameters:
.parameters
| [ keys_unsorted[] as $k
| if .[$k].isEncrypted == false
then { ($k) : .[$k].value } else empty end ]
