how can I reshape jq output?

Question

I have the following json data:

[
     {"name":"JSON", "good":true}, 
     {"name":"XML", "good":false},
     {"name":"JSON", "good":false},
     {"name":"HTML", "good":false},
     {"name":"XML", "good":true},
     {"name":"XML", "good":false}
  ]

by using :

jq '.[] | select(.name =="XML") | .good', result will be :
false
true
false

How can I make it like [false,true,false] as a record?

Answer 1

Just try wrap the whole expression within an array constructor, []

jq '[.[] | select(.name =="XML") | .good]'
[
  false,
  true,
  false
]

Or in a same line using the --compact-output flag

jq --compact-output '[.[] | select(.name =="XML") | .good ]'
[false,true,false]

Answer 2

In short: gather the results as an array, and use the -c option, eg

$ jq -c 'map( select(.name =="XML") | .good )'

Output:

[false,true,false]
