I have a dictionary which looks like:

cat dictionary.json
[
 
 "key": "key01",
 "value": "value01"
 ,
 
 "key": "key02",
 "value": "value02"
 ,
 
 "key": "key03",
 "value": "value03",
 "extraProperty": 
 "foo": "bar"
 
 ,
 
 "key": "key04",
 "value": "value04"
 
]

Then, I have an array which is:

echo $array
key01 key02 key03

Expected output:

value01 value02 value03

I have some trouble to make jq using an array which is not json format.
I tried various solutions that I found, but none of them worked.
This post jq - How to select objects based on a 'whitelist' of property values seems to solve a similar problem but it doesn't work with my input:

echo $array | jq --argfile whitelist dictionary.json 'select(any(.key== $whitelist; .value))'
parse error: Invalid numeric literal at line 1, column 6

I also tried to use

jq -n --arg array $array --argfile whitelist dico.json 'select(any(.key== $whitelist; .valuee))'
jq: error: key02/0 is not defined at <top-level>, line 1:
key02
jq: 1 compile error

Thanks!

Here

jq -r --arg array "$array" 
 'from_entries | .[($array | split(" "))]' 
 dictionary.json

Output

value01
value02
value03

See man jq for further information.

Using INDEX/2, which constructs a dictionary:

echo 'key01 key02 key03' |
 jq -Rr --argfile dict dictionary.json '
 INDEX($dict; .key) as $d
 | split(" ") | map( $d[.]|.value )
 | join(" ")'

yields:

value01 value02 value03

If your jq does not have INDEX, then now would be an excellent time to upgrade to jq 1.6; alternatively, you can simply snarf its def by googling: jq "def INDEX"
