Creating a Select Menu in bash using JSON input - json

Question

I am trying to create a menu using the select function in bash. I am accessing an API which will return its output in json format. I will then process what the API returns into a select statement where a user can then interact with.
Here is the API call and how I parse the output:
curl -H "Authorization:Bearer $ACCESS_TOKEN" https://api.runscope.com/buckets \
| python -mjson.tool > output.json
This will send the output from the curl through python's json parsing tool and finally into the output.json file.
I then create an array using this json blob. I had to set IFS to \n in order to parse the file properly:
IFS=$'\n'
BUCKETS=("$(jq '.data | .[].name' output.json)")
I then add an exit option to the array so that users have a way to quit the selection menu:
BUCKETS+=("Exit")
Finally, I create the menu:
select BUCKET in $BUCKETS;
do
case $BUCKET in
"Exit")
echo "Exiting..."
break;;
esac
echo "You picked: $BUCKET"
done
Unfortunately, this does not create the exit option. I am able to see a menu consisting of every other option I want, except the exit option. Every option in the menu and in the array has quotes around them. How do I get the Exit option to show up?

Answer 1

$BUCKETS is expanding to the first element of the BUCKETS array.
Which is then being word-split and used as your select entries.
This makes sense since you wrapped the jq subshell in double quotes which prevented word-splitting from happening there (and means the IFS change isn't doing anything I believe).
Iff your entries can contain spaces and you want that assigned to an array properly the way to do that is by reading the output of jq with a while IFS= read -r entry; do loop.
BUCKETS=()
while IFS= read -r entry; do
BUCKETS+=("$entry")
done < <(jq '.data | .[].name' output.json)
Then appending your exit item to the array.
BUCKETS+=(Exit)
and then using
select BUCKET in "${BUCKETS[#]}"; do
(Both select a in l; do or select a in l\ndo there's no need for ; and \n there.)
That all being said unless you need output.json for something else you can avoid that too.
BUCKETS=()
while IFS= read -r entry; do
BUCKETS+=("$entry")
done < <(curl -H "Authorization:Bearer $ACCESS_TOKEN" https://api.runscope.com/buckets | python -mjson.tool | jq '.data | .[].name')

Answer 2

Instead of
jq '.data | .[].name' output.json
try
jq -r '.data | .[].name' output.json
(-r : raw data without quotes)
And the most important part :
select BUCKET in "${BUCKETS[#]}"
